Putting aside the lengthy research process, if you look directly at the conclusions-

Advantages of both:

Dry desulfurization, simple industry, no sewage, low energy consumption, fast flue gas emission.

Wet desulfurization, desulfurization efficiency is higher, and the by-products of some processes can be sold for two dollars.

Disadvantages of both:

Dry desulfurization, expensive.

Wet desulfurization, wastewater.

So the results are clear, the wastewater is not my business, but the cost of waste water is affecting my livelihood.

Therefore, due to the price disadvantage of dry desulfurization, the use of wet desulfurization accounts for the absolute majority, and the same is true in the world. If it has to be said, the choice of desulfurization method is certainly not so reckless, and it should be determined according to the type of coal, the supply of preparations, the utilization of by-products, and various factors including geography, environment, climate and so on.

The flue gas is sprayed out of the boiler, first of all, through the baptism of deamination equipment and electrostatic precipitation, and the non-mainstream pollution is put into the ash pipe, and the mainstream flue gas enters the desulfurization equipment, in which the reaction occurs, due to the intervention of H2O (water), the process is more efficient, and the preparation is less, and the final product includes a large amount of gypsum in addition to calcium sulfate. If there is a demand in the market and the transportation cost is reasonable, you can sell the plaster, or throw it away, and you don't feel distressed.

So the plaster stuff is always very cheap!

To put it simply, in fact, dozens of large and small devices are needed in this process, and Zhang Yifu also requires a monitoring function, which involves microcomputer automation, and it is also necessary to reserve the interface with the Hengdian automation system to complete the great cause of Hengdian automation.

R&D from scratch will be a huge and complicated project, so most of the enterprises in this area in the previous life were directly engaged in the introduction of foreign technology. Hengdian was not introduced though. But Zhang Yifu himself is equivalent to living technology, all the equipment that is too demanding is inevitably imported from abroad, from the current report, Siemens can meet all the needs, of course, a few points, including Mitsubishi and other companies do better. This is a question for the future optimization phase.

Restricted by the office research and development conditions of the original second repair plant, as well as the requirements of the "Jijing City Air Pollution XXXX Regulations", it is difficult for Chang Siping's team to carry out the next step of the test in Beijing, and can only continue to carry out component production research and development, theoretical calculations, etc., and even has been docking automation with the Changjiang working group, so the factory in northern Hebei must be completed as soon as possible, so they can make a full set of products and assembly tests. Tons of gypsum are manufactured.

It can be said that the stage of theoretical research was easier than Zhang Yifu expected. Professor Chang Siping's level is not ordinary, he started working after a period of time, he is like a laid-off worker re-employed, very cherished, very motivated, very desperate, and now has entered the stage of production experiment. They need a platform, and it's urgent. If you delay the construction of the factory for a day, you will delay for a day to make money.

The train entered the station and greeted the lineup, which greatly surprised Zhang Yifu.

Although it surrounds the capital of Jijing, Ji Province has never been considered a rich province, with coal in the west, people in the south, and the sea in the east, and a great capital in the middle. It is like a hard-working elder sister, always feeding the capital, but never asking for anything, honestly doing its duty, and now the capital has thrown heavy industry and heavy pollution over. She had to obey the center, and then blew beautifully.

This is not a bad thing, as far as northern Hebei is concerned, in addition to the northern Hebei power plant and donkey meat does not seem to have much to get their hands on, a considerable amount of GDP is supported by power plants, and they also hope to have a factory with excellent benefits to settle here, and develop northern Hebei into a big city and a famous city.

It can be said that Hengdian is the first large-scale enterprise that intends to settle in northern Hebei, so the local government from the mayor, secretary, to various office directors, almost all came, forming a team of more than ten people to greet the entrepreneur, to let the entrepreneur feel the enthusiasm of the people of northern Hebei.

Zhang Yifu was stunned as soon as he got off the train, and this meeting was almost in time for the inspection of the central leaders, and he even arranged for a class of primary school students to come forward to deliver flowers wearing school uniforms.

Although the little girl who gave the flowers was full of smiles, her expression was very nervous, and she was acting out at first glance. She jumped up and down in front of Zhang Yifu according to the leader's instructions, and held a bouquet of flowers in both hands: "Welcome Uncle Zhang to settle down in northern Hebei!"

"Thank you, and I wish you to study hard and make progress every day. Zhang Yifu bowed down and took the bouquet.

Soon, several people in the entourage were treated similarly.

Everyone held the bouquet of flowers, and did feel the enthusiasm of the northern Hebei side, but also felt a little embarrassed, how could they let the children in the class put down their studies and wait here for an hour to send flowers to themselves?

At this time, several leaders stepped forward and shook hands with the Hengdian team one by one.

One-on-one, Zhang Yifu almost remembered the mayor because his name was too easy to remember - Chow Yun-fat.

However, in terms of appearance, temperament and conversation, he has nothing to do with Fa Ge, but is more like Niu Dameng, a swarthy man, who speaks very routinely, looks rough and chats finely.

To his surprise, Zhang Yifu found the old brother at the back of the greeting procession.

"Xiaozhuang?" Zhang Yifu saw Niu Xiaozhuang silently at the back of the team from afar, this guy has more beard, and he is fatter, and he is a little closer to the "orangutan" in Xia Xue's cognition, but he now has a little more of the taste of old-fashionedness, and it is also the taste of being a father.

"Shaw. Niu Xiaozhuang looked at Zhang Yifu and laughed, "Why are you a big boss, and you are still so unsophisticated?"

"What do you have to offer?"

The two laughed and hugged each other, this hug is still the old feeling, and it is angry!

Seeing this, Mayor Chow Yun-fat and Mayor Zhou also smiled and said: "Didn't you hear that Mr. Zhang used to work in our Jibei Power Plant, and he specially troubled the comrades of the power plant to come over." ”

"No trouble, no trouble. Niu Xiaozhuang still had this temper, and said to Zhang Yifu, "Let's not stay here, it will affect other people, and the children will not be able to go back." ”

"Yes, yes, let's go somewhere to talk. ”

Everyone got on the bus and went straight to the Jibei Hotel.

Zhang Yifu looked at the street scenes along the way and sighed slightly.

In less than 5 years, Jijing can be said to be changing with each passing day, changing a lot, and high-rise buildings are being built every day. Every day, the old houses disappear, the roads are getting wider, the cars are getting more, and the people are becoming more beautiful. Even the food stall outside the train station is still the boss, the guy.

If you don't say it, places like Baozhou, Shijiazhuang, and Langfang in Hebei Province may change greatly, and even Chengde may also be built because of tourism profits, but Northern Hebei really doesn't have this opportunity. It is close to Inner Mongolia, there is no big industry, and no one will come here to eat donkey meat, so it is really limited in livelihood.

It is precisely because of this that they attach so much importance to the settlement of Hengdian.

Because northern Hebei has never been a good place for enterprises to settle down, first, there is a certain distance from the highway, which is a short board for logistics, and secondly, the economy is not good. Talented people do not want to come, and they cannot be retained; third, the environment is not very pleasant; and fourth, the current economy has completed the transfer from the northeast to the southeast. It would be more comfortable to build factories in some places to the south, and the supply chain would be more comfortable.

As Zhang Yifu himself, it is almost the first time to make such a seemingly sloppy "imperfect" choice.

He didn't really think about it that much, he just wanted to give back to the city, or the countryside.

Look the other way around. The government of northern Hebei attaches great importance to it, and it is also hoped to seize this may be the only opportunity to retain this company.

In the car. The mayor has spared no effort to talk about the planning of northern Hebei, which will be opened to the highway in a few years, and the school hospital is also following the construction of Yunyun, always wanting to add a few points to northern Hebei.

Zhang Yifu naturally will not pour cold water, after showing similar amazement and expectation, he also began to blow, advocating several large projects of Hengdian, this time the unlimited opportunity of the environmental protection plant, if completed, will definitely drive the economic development of the entire northern Hebei Yunyun, employment will be deeper.

No, this kind of conversation between characters who are not so familiar with each other are trying to raise their own value, and Zhang Yifu seems to be low-key but not in the stream.

Entering the hotel, Zhang Yifu and his entourage first went to the room to rest, and the people from the northern Hebei side arranged in the banquet hall.

Niu Xiaozhuang came to the room with Zhang Yifu, and he was anxious when he entered the room.

"Fuck! There is still this kind of room in the North Hebei Hotel?" Niu Xiaozhuang is so angry, a large suite of 200 square meters, international standards, how can there still be such an existence in North Hebei, "This must be for the reception of big shots, and the presidential suite is like this, right? Looking forward to the chairman and prime minister or something, the big leader will come over one day, but it turns out that your kid will pick up the cheap!"

"Don't say it. Zhang Yifu is not surprised, this room is quite luxurious, but in fact, it is still slightly inferior to Kunming's room, but Niu Xiaozhuang has never seen the world, "If our factory is really settled here, I wonder if the prime minister will really come one day." ”

"You can blow it. Niu Xiaozhuang smiled disapprovingly, "Then I have to wait for my dad to become the prime minister, right? I just heard you brag with the mayor in the car, and I got goosebumps all over my body." ”

"Rare and weird. Zhang Yifu also scolded with a smile, put down his luggage, and walked into the bathroom, "It's uncomfortable on the train, I'll wash my face first." ”

Niu Xiaozhuang didn't see outside, just leaned against the bathroom door and chatted.

"How's your kid?"

"That's good, when you're done, go and see, you can run faster than you. Niu Xiaozhuang smiled and said, "Originally, I wanted to have another one, but my father refused to let me live or die, saying that unless I didn't want to be a cadre." ”

"Forget it, discipline is here, you are also a power plant leader, how can you take the lead in superbirth. Zhang Yifu also helped him persuade Uncle Niu.

"If you can afford it, why don't you let it?" Niu Xiaozhuang still disagreed, "Besides, if you are not a cadre, you are not a cadre, I can't just ask you to do it?"

"Private enterprises also have discipline, family planning is a national policy, some people have more children, and all aspects will be under pressure. Zhang Yifu continued to help him Uncle Niu.

"We have a relationship, and you will fire me if you put some pressure?"

"That's, I won't open you when the prime minister points at my nose, and your son is also my son!"

"Why does it sound so awkward to me!"

"Haha. Zhang Yifu wiped his face with a towel and laughed, "Seriously, if you want to have one more, you can use legal means to give birth, but it's a little troublesome." ”

"What's the matter?"

"You divorce Jingjing, the child is given to you, she is single and finds a man who has never given birth to a child to get married, and then gives birth to one with you, with Jingjing's surname, they will leave again, you two will get married again, if you want to, change the child's surname, and ...... with your surname" (to be continued......)
