Chapter 27 Sediment Control Steam Turbine Power Generation

Just finished recruiting students, Lu Chengxiang and Lu Bingyi came to find Zhang Zhimu together.

Seeing the two of them, Zhang Zhimu didn't arrive at the reception room, so he asked Yang Yulin to serve this year's Ming Qian tea in his office. Now several giants in Yaogang look like they are all in high spirits. They have reason to be happy, and they have reason to be a little more relaxed.

The three of them tasted tea for a while. Lu Bingyi said: "Good news to Mr. Zhang! After our fertilizer is divided, the effect is simply great. Now the crops are growing black and strong, and the old farmers who have been farming for many years also say that they have never seen crops that grow so well. Mr. Lu and I are here to suggest to you that we should expand the production capacity of chemical fertilizers. At present, our fertilizer production cannot meet the needs of Shanxi, let alone Shaanxi, which is about to be considered. ”

"Huh! I have asked Qingfengzi to expand an ammonia plant. With this set of ammonia plant, the production capacity of chemical fertilizers will be greatly improved. Our fertilizers now have phosphorus and nitrogen fertilizers, but less potassium fertilizers. We're going to do synthetic fertilizer in the future. Mr. Lu, the group that you are working on the use of chemical fertilizers needs to be strengthened. In the future, we will measure which kind of soil is lacking in that kind of fertilizer and then apply fertilizer as needed. And what crops have a good fertilization effect at what time must be observed and analyzed. You can even make some experimental fields and do comparative analysis. ”

"That's right! I'll arrange this when I get back. Lu Bingyi said, "This is a matter directly related to grain production. ”

"In my opinion, it is not enough to build another fertilizer production line." Lu Chengxiang said, "We have more and more land reclaimed in Baotou and Dongshengzhou. More and more fertilizers will be needed. ”

"I've thought about this, and we're going to build another large-scale ammonia production plant in Baotou in the future," Zhang Zhimu said, "and this matter should be considered together with the Baotou master plan." ”

Lu Bingyi asked: "Mr. Zhang! I heard that you are planning to build a large iron and steel enterprise in Baotou? ”

"Yes! We're going to look into this next. Zhang Zhimu said, "However, I want to study the issue of the Yellow River and the Fen River with the two of you today. ”

Lu Chengxiang and Lu Bingyi glanced at each other, but they didn't understand why Zhang Zhimu wanted to study the two rivers.

Zhang Zhimu asked them: "You all know that the water of the Yellow River and the Fen River has a high sediment content, why is that?" ”

"The Loess Plateau has a thick soil layer, so there is more sediment washed down?" Lu Bingyi said.

"If this continues, the dams in the lower reaches of the Yellow River will have to be built higher and higher, and they will never be bigger." Zhang Zhimu said, "Since we are about to take charge of Shanxi and Shaanxi, which are the source of sediment in the Yellow River, we should find a way to solve this problem." ”

Lu Bingyi's eyes lit up when he heard Zhang Zhimu's words, "If this problem can be solved, it will be a great merit!" Do you have a way? ”

"We haven't thought about it yet, but there's one thing we have to do. It's probably going to be a bit tougher. "We first need to plant trees and grass on both sides of the Yellow River and the Fen River to reduce soil erosion and reduce the amount of sediment entering the river." Returning all the slopes along the river to forests, and building a shelterbelt along the river. Felling of trees along rivers is prohibited, as well as in the tributaries of the Yellow River and the Fen River. Violators will be punished heavily! ”

"It's really difficult," Mr. Lu said, "and we have to enact strict laws, and we have to have people strictly inspect and enforce them." However, if the problem of sediment can be solved, it must be done as well. ”

Lu Bingyi also said: "Those slopes by the river don't produce much, but they do a lot of harm. Let's make up our minds to solve these problems first. However, we also need to consider the issue of compensation for those who have returned farmland to forests. ”

"It's not a matter of saying yet. First of all, our officials should count the number of acres of land along the river, and then issue a decree to return farmland to forests within a time limit. Compensation is then made on a case-by-case basis. Lu Chengxiang said.

"Also, we are going to build several nurseries from now on to nurture saplings. For those riverside areas, it is best to plant some shrubs such as wicker, which have a well-developed root system and a strong sand-fixing effect. Then it is paired with fast-growing tree species and drought-tolerant tree species to take a generation to control the worsening problem of soil erosion. Zhang Zhimu said.

"Hey! The land of Sanqin was originally lush with trees, and later Qin Shi Huang repaired the Afang Palace and cut down all the trees. The 800-mile Qinchuan River was originally a place to supply grain to the Sanjin Dynasty, but now it has to use wood and grain from Shaanxi. Lu Chengxiang said, "If we don't plant trees, I don't know what will happen there in the future." ”

"Tree felling is not a matter of Qin Shi Huang's generation," Mr. Lu said, "but I think even that will reduce some sediment." The bottom of the Yellow River is cut into the Loess Plateau, and it will wash away a lot of soil, which is no choice. ”

"Actually, I see that your sewage treatment plant treats sewage and presides down impurities, which can be used for the treatment of Yellow River water." Zhang Zhimu said.

"How big a treatment plant do you have to build?" Lu Chengxiang felt that Zhang Zhimu's idea was a bit outrageous.

"Huh! You can listen to me before commenting. Zhang Zhimu said, "We will build a large reservoir on the left and right sides of the main trunk of the Yellow River, and the reservoir will be dug deeper. We first put the water of the Yellow River into the reservoir on the right, and when the reservoir is full, it continues to the downstream channel through the outlet. Due to the large size of the reservoir, the flow rate of the Yellow River water into the reservoir area decreases, and the sediment sinks to the bottom of the reservoir, and after a few years the reservoir bottom is filled with sediment, we close the entrance and exit of the reservoir on the right. Open the inlet and outlet of the reservoir on the left and filter the sediment through the sediment of the reservoir on the left. At this time, the reservoir on the right, which has no water source, will slowly dry up, so we will dig up the sediment from the bottom of the water and transport it out. In this way, if we change the reservoir every few years, will we be able to filter the sediment of the Yellow River? ”

"That's a good idea," Mr. Lu said, "and we could build a few of these projects in the Yellow River Basin." Even several tributaries can build such a filtration reservoir. ”

"How much work does it take, how much manpower does it take?" Lu Chengxiang was speechless when he heard it.

"It's worth it compared to building a dam every year and not knowing when it will burst." Zhang Zhimu said, "In the future, we will also build a flood storage dam on the Yellow River to ensure the flow rate of the Yellow River water during the dry season, scouring the river channel and reducing the sediment deposition of the Yellow River." Comprehensive management of the Yellow River. ”

"If the Yellow River can be managed well, the world will be at peace." Lu Bingyi said, "Mr. Zhang, we have done it, no matter how many difficulties we have, we can overcome them." ”

"Hey, hey!" Lu Chengxiang said, "Hearing you say this, I have an idea. There are many deep canyons in the mountains on the edge of the Yellow River, can we dig the mountains and bring in the water of the Yellow River, and wait for the sediment of the Yellow River to fill the valleys, and then plug the openings, can we create good land? ”

"Absolutely! But you need to find such a place. Zhang Zhimu said, "This is the best thing to do with one stone." ”

"We should have prepared for this kind of thing earlier. I think we will build a large seedling base outside the customs, and I will do this. We can also build a few such bases in Shanxi, because the demand for saplings will be very high. Lu Bingyi said, "As for the matter of returning farmland to forests, we still need to discuss it together and work out detailed and feasible policies." If you don't plan things in detail, you can't carry them out. ”

"Okay! I'll leave this matter to Yan Xing and Li Yan to study in detail. Let's take out an opinion first, and then we will study and supplement. Zhang Zhimu said.

The good news that the leaders of a kiln gang were looking forward to finally came, and the Niutoushan steam turbine generator could finally generate electricity. Before this power generation, Li Di replaced all the transformers used in the existing power grid, because now with transformer oil, transformer oil insulation is much better than air, and it is easy to dissipate heat. They also upgraded the 10,000-volt grid to 110,000 volts. To this end, Li Di and his team built an electric power laboratory in a ravine in the suburbs. A large number of experiments were carried out there on high-voltage insulation. Although there are many results from the experiment, such as the number of porcelain bottles that need to be hung on the 110,000-volt line. However, due to unease, a few more insulated porcelain bottles were added to the high-voltage wire. Due to the increase in voltage, the diameter of the high-voltage wire transmitted from Niutoushan to Yaogang has been reduced a lot, and a lot of copper has been saved. In order to reduce the high-voltage line towers and increase the spacing of the high-voltage towers, Li Di adopted Zhang Zhimu's suggestion to erect steel cables between the high-voltage towers first, and then hang copper wires.

Due to the experience of the previous generators connected to the grid, the grid connection of the 10 MW generator was very smooth. The grid-connected ceremony of this generator set was also attended by the leaders of the kiln, and the radio station also broadcast it live. After visiting this generator set, Zhang Zhimu and the others also visited the construction site of the 100-megawatt generator set.

Li Di said: "We have not finished the design of the 100-megawatt unit, but the civil part has been completed, in order to be in a hurry. Carry out civil works that can be built first. Now with this 10-megawatt unit, we are aiming to be able to generate 100-megawatt units next year. Because there is no need to repeat the construction of ancillary facilities such as coal transportation and crushing coal, only the generator set will be built this time. So the construction will be fast. ”

The third child of Niutou Mountain can no longer see the appearance of the original mountain king. Although Niutou Mountain is now full of people and miscellaneous people, the third child manages Niutou Mountain in an orderly manner. Zhang Zhimu was also very happy to look at it. Yan Xing has also been busy for a long time and hasn't come back, and he is even happier to see that the third child has done Niutoushan so well.

Of course, the two newspapers of Yaogang made a more auspicious report on the grid-connected power generation of this unit the next day. A large photograph of Tomoki cutting the ribbon was also published.

With sufficient electricity, Liu Baoxue also opened the experimental electrolytic furnace of electrolytic aluminum and electrolytic magnesium in the smelting field for trial production. Although the aluminum and magnesium produced by the electrolytic furnaces of these two experiments were not enough to produce anything else, they still provided actual samples for Qingfengzi to conduct chemical experiments.

After getting some aluminum and magnesium ingots, Zhang Zhimu called Li Yunhe and invited him over.

As soon as Li Yunhe entered Zhang Zhimu's office, he saw two large pieces of silver shining on the table, and joked: "Mr. Zhang doesn't have to be so polite, give me such two pieces of silver!" ”

"Humph! Beautiful you! Zhang Zhimu pointed to two pieces of things and said, "You pick it up and weigh it!" ”

Li Yunhe went over and picked up these two things and turned them upside down, saying, "It's not silver, the weight is wrong." It will be metal aluminum and metal magnesium. I heard from my father that they had already started producing this thing. ”

"You're smart!" Zhang Zhimu said, "This is exactly a piece of aluminum and a piece of magnesium. ”

"Didn't you give it to me?"

"I want you to make flares out of them." Zhang Zhimu said.

Seeing Zhang Zhimu talking about business, Li Yunhe put away and sat down with a smile, "Tell me specifically, what's going on with this flare?" ”

"When the aluminum and magnesium are burned, they emit a high amount of heat and emit a dazzling light, and the effect of burning magnesium powder and aluminum powder together will be more obvious. In this way, you use aluminum and magnesium to beat aluminum and magnesium into powder with a ball mill in isolation from the air. Then use shellac to bond magnesium powder, aluminum powder, and sodium nitrate together to make a column, and you hang it and light it from one end, and it will emit a dazzling light until this column is burned. If you shoot them into the air with a mortar and open a parachute in the air, they will slowly land, and then you will ignite the pillar with a time-delay fuse, and they will burn in the air, and they will shine brightly underground. That's what flares are. Of course, you can also develop flares fired from guns. It's up to you to experiment with how to do that. Zhang Zhimu gestured and said.

"Why do you need to add sodium nitrate?" Li Yunhe asked.

"Because sodium nitrate produces a lot of oxygen after combustion, which helps magnesium and aluminum burn." Zhang Zhimu explained, "The shellac is both a binder and an insulating agent to ensure that they don't burn out all at once. A flare can burn for twenty to thirty seconds. ”

"I didn't expect this thing to have this effect." Li Yunhe sighed.

"Not only that," Zhang Zhimu said, "You can say that if you add ten percent of the aluminum powder to the *****, then the power of the elevator aluminum ** will be much higher, and the explosion temperature will be much higher than that of pure *****." ”

"Oh my God, the aluminum plant in Baode doesn't know when it will be put into operation." Li Yunhe said, "I can't wait. ”

"You can add some aluminum powder to Lu Wenchen's flux, and their welding temperature will be increased a lot, and the welding will be easier and the quality will be better." Zhang Zhimu said, "The top priority is that you can make a water bottle for the soldiers out of aluminum, which is not easy to rust and is light." ”

"What? You want to make a kettle for a soldier out of baby aluminum. Li Yunhe was a little surprised.

"Hey, hey! You're wrong, there's a lot more aluminum than copper. There are aluminum mines everywhere, and as soon as the aluminum plant in Baode is put into operation, aluminum is not a new thing? ”

"Oh!" Li Yunhe looked at Zhang Zhimu a little confused and asked, "How do you know this?" Are you really a god? ”

"Nonsense, I'm an immortal and I still use your hard work to get this." Zhang Zhimu said, "As for how I know, I need to keep it a secret." Do as I say! ”

Autumn has arrived, and the happy events of Yaogang are also one after another, first of all, the railway to Datong has been opened. On behalf of the prince, he personally sent people to the kiln gang and invited Zhang Zhimu and the leaders of the kiln gang to Datong to attend the opening ceremony.

There was no way, so several leaders of Yaogang decided to participate as much as possible if they could, so as not to disappoint the prince on behalf of him.

Zhang Zhimu: They went to Datong by train this time. Due to the convenience of the road, Huang Yukun also went with Zhang Zhimu, and the red lady and Mrs. Zhou Yuji, seeing Huang Yukun go, they also followed. Due to the small size of the child, Yang Yulin can't go, and she can't be in a hurry. Xiao Hongyu heard that there was such a thing, so how could she miss it, so she also followed.

On the train to Datong, everyone was very relaxed and came to the dining car to drink tea.

Ouyang He said to Zhang Zhimu: "Now that the train is connected to Datong, even if our northern Shanxi is connected, it is easy for us to support each other if there is something in the north." ”

Zhang Zhimu said: "This time, we are going to bring Zhou Yuji on the road. After arriving in Datong, I also want to talk to Jiang Zhuo's general soldiers, and when we send troops next year, we can borrow troops from them if we don't have enough troops. My only concern was that when we sent our troops, the Manchus and Mongols would make moves in the north, and we were a little nervous at that time. I'd like to say hello to them sooner, but hopefully I don't need them. ”

"As long as General Zhou sends people to watch over several passes on the Great Wall of more than 1,000 kilometers in Shaanxi. In fact, we are on the front line of Baotou and Dongshengzhou, and we can completely block the threat from the north, and if it were not for the large-scale attack of the Manchus and the Mongols, ours would be able to block it there. The reason why General Zhou was asked to send troops to guard those passes was also to keep them from being destroyed. I don't think the Great Wall will be of much significance in the future, but it will only be able to block a little bit of the wind and sand in the north. ”

Chen Yufeng said: "After we go back, we should enter the final stage of preparation. In the spring of next year, as soon as the Yellow River opens, we will be able to act. Our soldiers are coaxing one by one, I don't know what will happen then? ”

"Huh! We're ready for it. Ouyang He said, "I think that our march into Shaanxi is completely military training." One is to train the army, and the other is to train our officials. There is basically no suspense. Just pay as little as possible. ”

When he arrived in Datong, Zhang Zhimu did not expect that the acting prince and Jiang Zongbing would arrange a grand welcome ceremony at the train station. Not only did Jiang Zhuo personally greet him at the station, but even the royal guards came out to greet him. A large row of steel spring carriages took Zhang Zhimu and his party to an inn chartered by the Datong branch. Due to a few stops on the road, it was a little late to Datong, but the prince still personally set up a banquet in the palace to entertain Zhang Zhimu and them. This touched everyone.

At the royal banquet, not to mention the wine and food, it is extremely luxurious. During the banquet, after the prince introduced his own princes to Zhang Zhimu and all of them, he said to his princes: "If you don't talk about anything else today, let's talk about the banquet." You might think our wine is already a big deal, don't you? ”

The princes did not answer, apparently not objecting. But the king said to them, "But if these are compared with the dishes of the Yaogang Hotel, we are just the coarse tea and light rice of the countrymen." "What Dai Wang said is a bit exaggerated, but their dishes really can't be compared with the dishes made by masters such as Huaiyang cuisine, Fuzhou cuisine, and Sichuan cuisine.

Looking at the princes' expressions of disbelief, the acting king said, "If I hadn't stayed in the Yaogang Hotel for a few days, I wouldn't have believed in such a thing. Let me tell you, if our Daiwang Mansion is compared with the Yaogang Hotel, it will be an earthen house. Now that the railway is open, you should not all stay at home, but also go out to the kiln to have a look, and if you don't go out, just look at the things in front of you. Never know what's going on out there. ”

Zhang Zhimu hurriedly said: "Welcome to the princes to our kiln!" ”

The acting prince is really not an ordinary prince, he took over and said: "Zhang Dongjia listens to me. In the future, no matter who goes to Yaogang to live in Yaogang Hotel, he must spend silver according to the price, even if I go again, I should spend a penny of silver. And so they should go. ”

"Will that work?" Zhang Zhimu couldn't agree.

"That's right," said the acting prince, "if I can do this, I can go to the kiln a few more times." To be honest, I have long wanted to go to the Yaogang Hotel for a few more days. But when I go, you won't let me spend money. I'm too embarrassed to go again. Originally, I also wanted them to go to the kiln to have a look, but I was also afraid that you would break the bank. So I've been letting them go all the time. ”

"It's all a small thing." Zhang Zhimu hurriedly said.

"I think this is Zhang Dongjia, no matter who we are, we have to talk about friendship. From now on, whether it is me or them, no matter who goes, the money of the room will be spent on whatever kind of room you live. In fact, in the past, they didn't necessarily have to live in that kind of superb large suite. The junior suites are already very good. As for me going, you invite me, and when I come to Datong, I will invite you, it's nothing. If you could promise me. We could go a few more times. ”

"Alright! Just listen to the king. Zhang Zhimu had no choice but to say this.
