Early the next morning, Geng Zhiyuan took Song Chen and Chen Xin to get in the car and rushed to the Haibin County Fertilizer Factory. On the road, Geng Zhiyuan had been meditating with his eyes closed, considering countless possible causes and consequences, as well as solutions, and the atmosphere in the carriage seemed slightly solemn under the silence.

In this atmosphere, Song Chen felt very depressed, and couldn't help but complain: "Teacher, I don't know the technology of the nitrate project that we provide, and the equipment conditions are also proposed by the science and technology, why should you look for us if there is a problem?" ”

Geng Zhiyuan opened his eyes and smiled slightly: "Xiao Song, you can't say that." ”

Song Chen pouted and said, "What's wrong?"

"The truth is this, but after all, the drawings are from our hospital, and we will help solve the problem if there is a problem, and shirking responsibility will not help solve the problem, and it will also ruin the relationship. ”

Geng Zhiyuan explained carefully: "If we push the responsibility to the science and technology, we think it is a matter of course, but the factory will not think so, they will think that we are unwilling to help them solve the problem, how can people give us the design fee owed." ”

Chen Xin said on the side: "What if we can't solve the problem?"

Geng Zhiyuan sighed and said: "We have done our best to have a clear conscience, if the factory resolutely refuses to give, our design institute has no way at all." If you don't believe it, the money owed to our hospital outside must be millions. ”

The driver, Master Zheng, turned his head and said: "Geng Gong is right, none of these enterprises served by our hospital do not owe us money." Tens of thousands, hundreds of thousands, and hundreds of thousands, add up to an astonishing amount. ”

"Isn't there a contract, can you file a lawsuit?" Song Chen was puzzled.

Geng Zhiyuan smiled bitterly: "If our institute files a lawsuit with the company for design fees, I'm afraid no one will ask us to do projects in the future." ”

"Why? There are so many chemical companies in the country, he doesn't look for us, let's look for someone else?" Chen Xin asked with a glare.

Geng Zhiyuan saw that the two girls were too young, so he had to explain: "I remember telling you that there is no perfect design in the world, and any design will have more or less problems. ”

"Well, we've heard you. Song Chen nodded.

Geng Zhiyuan said: "It is too easy for enterprises to find a design institute to make mistakes, and it can be said that from the moment the drawings are delivered, the design institute will hand over its handle to the other party." In this case, do you think we can win the lawsuit?"

The two girls couldn't help but shake their heads, and Geng Zhiyuan continued: "If you can't win a lawsuit, people can still use the lawsuit to stink your reputation, and the original friendship between them is gone." For the sake of a lawsuit, the money was not obtained and the reputation and good relationship with the company were lost, do you say, is it worth it or not?"

The two girls suddenly realized at this point, and shook their heads and said, "It's not worth it!"

Therefore, it is the norm to owe design fees, and those who do not owe design fees are true friends. Geng Zhiyuan sighed: "As for those units that owe us design fees, our institute not only dare not offend, but also have to greet them with a smile, in order to find us to do it if there is another project." ”

"Alas!" Geng Zhiyuan sighed and said: "The name of the Provincial Design Institute sounds lofty, but in fact it is just a weak person who looks up to others and begs for food. ”

Master Zheng sighed with emotion: "Geng Gong is worthy of being an old comrade, and he can see it very accurately!"

At more than nine o'clock in the morning, the group arrived at the fertilizer factory in Haibin County. Geng Zhiyuan went to convey his intentions, and Zhang Chengjin finally gave some face, and informed them to allow them to enter the factory.

Finally seeing Zhang Chengjin, Geng Zhiyuan squeezed out a smile and said: "Director Zhang, I heard that there is something wrong with nitrate, and the hospital sent us to help the factory solve it." ”

Zhang Chengjin is not a technical cadre, although he knew that there was a problem with nitrate, but he couldn't say why, he touched his chin and was cold for a while before saying: "Okay, let's go to the scene and talk about it." ”

Geng Zhiyuan didn't know what kind of medicine he was selling in his gourd, so he put on a hard hat and followed Zhang Chengjin to the production site of the nitrate plant.

Zhang Chengjin called Li Yan, the director of the nitrate workshop, and instructed him: "Director Li, this is from the design institute, you tell them what the problem is." ”

During the design of the nitrate project, Li Yan had dealt with Geng Zhiyuan and others and were very familiar with each other. Li Yan is an open person, and said without scruples: "What happens in production has nothing to do with the design institute, and the process is not theirs, so it's useless to complain about others." ”

Zhang Chengjin's face was gloomy when he heard this: "Why doesn't it matter?

Geng Zhiyuan saw that he insisted on going his own way, and hurriedly grabbed Li Yan and said, "Li Gong, you tell us about the situation first." ”

Li Yan glanced at Zhang Chengjin and introduced kindly: "The absorption effect of the absorption tower is not good, not to mention the high concentration of tail gas, and the concentration of the mother liquor cannot be raised." ”

"Have you clarified your question?" Geng Zhiyuan asked in a low voice.

Li Yan glanced at Zhang Chengjin and whispered: "The factory didn't give the promised money to Lao Liu, and played tricks on the two of them, where am I embarrassed to ask others." ”

"Oh? That's a problem. Geng Zhiyuan took a cool breath and said.

"Who's to say it isn't. Li Yan complained: "This set of things shouldn't have been put on in the first place, and after it was built, it didn't even achieve a day's normal production, so it was parked here in vain, and all the money invested in it was wasted." ”

Although this is the case, since it is here, it is necessary to find out the cause and find a way to solve the problem anyway. Geng Zhiyuan looked up at the absorption tower dozens of meters high: "Please ask someone to open the manhole cover at the top of the tower, I will go up and take a look, and pump the liquid to the top of the tower to see the effect." ”

Li Yan said kindly: "It's raised, it's dangerous on top, I'll just let the workers go up, don't go up." ”

Only with first-hand information can we find out what the problem is, Geng Zhiyuan insisted: "No problem, it's not like I haven't climbed the tower." I've been up to hundreds of meters of granulation towers, and this tower is nothing. ”

Li Yan saw that he was resolute and admired: "Geng Gong is really a dedicated person, I will arrange for someone to go up immediately." ”

Song Chen and Chen Xin looked up at the absorption tower dozens of meters high and the simple ladders and platforms, and said in fear: "Geng Gong...... Shall we both go up too?"

Geng Zhiyuan handed the bag he was carrying into her hand, and smiled indifferently: "Don't go, I'll just go up by myself." ”

The two girls' hearts warmed, and they told them repeatedly, "You have to pay attention to safety." ”

"Don't worry, you can't fall off. Geng Zhiyuan fastened his helmet, walked to the bottom of the absorption tower, raised his hand to grab the bottom beam of the straight ladder, and slowly climbed up with his hands and feet.

The absorption tower is generally set up with a rest platform of three to five meters, and the platforms are connected by straight ladders. After climbing three straight ladders in succession, Geng Zhiyuan took a breath on the rest platform, and then continued to climb up, climbing to the top maintenance platform of 27.5 meters in one breath.

The so-called platform is nothing more than a steel grille with a width of only about one meter, and when you look down, you can see the tower and the ground through the grille holes. Standing on the narrow platform hanging high above the tower wall, people have a kind of psychological fear of being overwhelmed by the cold.

The manhole at the top of the tower has been opened, the workers are flashing to the side, Geng Zhiyuan probe looks inside, and the trough disc liquid distributor and the sieve tray plate are clearly displayed in front of him.

"Tell the underground to turn on the pump. Geng Zhiyuan said a word to the worker, and the worker picked up the walkie-talkie and shouted a few words. When the circulating pump is turned on, the yellow-green mother liquor gushes out of the feed pipe and is distributed to the sieve tray through the trough distributor.

"Huh......" Geng Zhiyuan was taken aback, only to see that the yellow-green liquid was tightly distributed on less than half of the tray, and the rest of the trays had no liquid distribution at all.

"Tell me, is it the material that is delivered according to the normal flow rate?" Geng Zhiyuan asked the worker again. The worker took the walkie-talkie and asked a few words, and then replied: "It has been hit up according to the maximum flow." ”

"That's not right!" Geng Zhiyuan said in his heart: "Even if there is no gas support, it shouldn't only soak half of the tray." It seems that this is the problem. ”

"Alright, tell them to stop pumping, let's go down. Since the root of the problem has been found, there is no point in staying any longer, Geng Zhiyuan commanded, and then began to climb down.

When you climb the ladder straight up, you can't feel the height of the position, and the human psychology is not too scared. When climbing down, you need to keep an eye on the landing place from time to time, and you have to step on the beam, so you have to look down.

Twenty or thirty meters tall was enough to make people dizzy, Geng Zhiyuan held his breath, forcing himself to focus on the rhythm of his feet, trying not to think about the height and danger.

Finally came to the ground, and as soon as his feet stepped on the ground, his heart finally relaxed. At this time, he realized that his two hands were already covered with rust due to grasping the ladder.

"Is there a gain?" Li Yan hurriedly came over to support him.

Geng Zhiyuan steadied himself and nodded, "I can see something." ”

"Oh?" Li Yan asked curiously, "What's going on?"

Geng Zhiyuan squatted down on the spot, picked up a small stone and drew a circle: "The mother liquor soaked half of the tray at most, I suspect that the diameter of the sieve plate hole is a bit large, the liquid distribution is uneven, and the absorption effect will of course be not good." ”

"Well, that makes sense. Li Yan asked again: "The towers are all erected, is there any way?"

Geng Zhiyuan thought for a while and said: "Let's go back and calculate, if the hole is really big, you can use a PTFE rod to plug it, and then make a small hole in the rod." ”

"Good idea!" Li Yan turned his head to Zhang Chengjin beside him and said, "Director Zhang, is this plan okay?"

Zhang Chengjin knew whether to do it or not, and said vaguely: "Ah...... This one...... Let's talk about research. ”

Li Yan knew his details, and secretly laughed but didn't dare to show it, but just said: "Then trouble Geng Gong to calculate the results as soon as possible, and we can improve it." ”

"Okay. Geng Zhiyuan breathed a sigh of relief and said in his heart: "Anyway, it is a good thing to be able to give an explanation to the factory, at least it can reflect our sincerity and level." ”

In the end, you have to rely on the level of technology to survive.
