The pipeline that caused the accident was the vent pipe of a safety valve on the gas ammonia pipeline before the ammonia water cooler, and the vent pipe, which should have been vertically upward, was almost lying flat on the ground, and the outlet elbow touched the ground to form a support, otherwise the whole pipeline would be broken.

Geng Zhiyuan took a closer look at the safety valve and found that the tee connected to the main pipeline was also bent into a 45-degree angle. Thankfully, there were no fractures in the elbow and no ammonia leakage.

Geng Zhiyuan shook his head when he saw it, he could see at a glance that the root cause of this accident was that the pipeline was not properly arranged, and the end of the vertical venting pipe should not be designed to be discharged horizontally.

Geng Zhiyuan stood up, pointed to the safety valve and said, "He Gong, the problem is still in the piping." ”

He Fengwen frowned: "What's the matter?"

Geng Zhiyuan explained: "This accident is almost the same as what happened in Jingzhou Petrochemical that year, and the root cause is that the safety valve is emptying the pipe outlet without support, and the pipeline deformation caused by the discharge reaction force. ”

He Fengwen frowned and said, "Is it......?"

Han Zhiqiang was unconvinced: "How is it possible? The original drawings were matched like this, why didn't there be an accident?"

Geng Zhiyuan glanced at him and said, "Just because there was no accident in the past doesn't mean that there won't be an accident, but it's just that it's not time for an accident yet." ”

Han Zhiqiang is a master's student in the Department of Chemistry of Tunghai University, who only came last year, and he has a high degree of self-education, and he looks down on Geng Zhiyuan, who graduated from the bachelor's degree. In his view, Geng Zhiyuan was just shirking his responsibilities, so as not to be seen as incapable of finding the real cause of the accident.

"Is what you say? Who do you think you are?" Han Zhiqiang directly forced him, without saving face for Geng Zhiyuan.

Geng Zhiyuan saw him playing a trick, and said coldly: "This is just my personal opinion, if you don't agree with it, you can tell me your opinion." ”

Last year, when the synthetic tower was hoisted, He Fengwen owed Geng Zhiyuan a good favor, and when he saw that Han Zhiqiang was not polite to speak, he hurriedly said: "Xiao Han, how can you talk to Geng Gong? Geng Gong is an expert in stress analysis in our hospital, is what people say casually?"

Shi Jingen had seen Geng Zhiyuan's ability to deal with it on the spot, and believed that his analysis was reasonable, so he asked: "How does Geng Gong think that this place will not be changed so that there will be no more accidents?"

Geng Zhiyuan thought for a while, picked up a stone and said while drawing on the ground: "It stands to reason that the discharge port should be upward, and the bottom should be set up with tear holes to drain the water, but the ammonia pipeline here is too thin, and the tear holes are easy to freeze in winter. ”

Du Hongyi said: "There are a lot of such pipes, should you change them all?"

Geng Zhiyuan said with a smile: "Not necessarily something will happen, the reaction force is related to the pressure and the size of the pipe." The pipe is thin, but the vertical pipe is too long. The vent reaction force at the outlet is not necessarily large, but if it is applied horizontally to the pipe end, the torque transmitted to the root of the safety valve will be too large, so it will be bent. If there was a support at the end of the pipe, this would not happen at all. ”

After He Fengwen understood, he said: "Go back, I will ask the designers of each section to check again, and if there are problems, they will be changed according to your requirements." ”

Han Zhiqiang is still unconvinced, thinking that he copied the original drawings and should not blame himself for the problem.

Geng Zhiyuan was annoyed when he heard him mutter, turned his head and reprimanded: "Even if the old drawings are designed like this, nothing has happened to them." The current installation is installed according to the drawings you designed, who do you want to find if something happens?"

Han Zhiqiang stiffened his neck and defended himself: "I copied it according to his drawings, of course you can't blame me if something happens." ”

"Then who should blame the designer of the old drawing? Is it someone begging you to copy it?" Geng Zhiyuan sneered: "You can copy the right one, you can copy the wrong one, who will you find if something happens?"

Han Zhiqiang was unconvinced, He Fengwen had to reproach: "Okay, fortunately, nothing serious, Geng Gong taught you a few sentences, you just remember not to make the same mistake in the future?"

The cause of the accident was found so quickly, and a solution was given, and the big problem became a small thing in an instant. Shi Jingen finally put his mind at ease and said to Geng Zhiyuan with a smile: "Geng Gong, please have a drink at night?"

Geng Zhiyuan waved his hand again and again: "Mr. Shi, you know that I don't drink, just have a light meal." ”

"That's not going to work. Shi Jingen pointed at He Fengwen and said: "I have learned He Gong's amount of wine, and I have to have a good drink with you this time." ”

He Fengwen never left his body for smoking and drinking, he was not only a drunkard but also a smoker, and laughed when he heard the words: "Okay, I'll have a good drink with him, let's not get drunk and go home." ”

Drinking and smoking are the two magic weapons that bring the relationship between the two sides closer, but it's a pity that Geng Zhiyuan doesn't touch any of them, so when it comes to the ability to engage in relationships, compared with He Fengwen, it can't be compared with heaven and earth.

Shi Jingen and others had to deal with other issues on the spot, so Geng Zhiyuan and He Fengwen rushed to the town's fertilizer factory guest house by car. Along the way, Han Zhiqiang still held his head high angrily and refused to pay attention to Geng Zhiyuan, and He Fengwen, who was watching it, could only shake his head secretly: "Xiao Han is still too tender, isn't this offending people for no reason? It is really unwise for young people to be angry with old comrades! Alas!"

When the car arrived at the guest house, Geng Zhiyuan got out of the car and suddenly saw many people on the street shouting and running in the direction of the fertilizer factory. He was surprised, and asked the doorman, "Man, what's going on?"

Seeing that there was no one left and right, the doorman whispered in his ear: "There was an accident in the factory the day before yesterday, and a squad leader in the nitric acid workshop died. The family thought it was a work injury, but the factory did not agree, and it was not this afternoon that the family took someone to block the gate of the factory. Alas, miserable!"

"Oh?" Geng Zhiyuan's heart sank. The chemical industry deals with high-temperature, high-pressure, toxic and flammable media all day long, and despite all the safety measures currently considered, it is impossible to avoid all accidents and can only minimize the possibility of accidents.

Geng Zhiyuan once compared the image of chemical production to dancing on the tip of a knife. Only the most daring can dance on the tip of a knife, but even the most skilled dancers must always be careful, because the slightest carelessness can be life-threatening, and if you don't do it well, your life will be lost.

It can be seen that it is not easy for the chemical workers who support their families to earn this money.

During the construction of the nitric acid plant of the Haibin County Fertilizer Plant, Geng Zhiyuan had served here for several months, so he was familiar with it and had a special feeling.

Hearing that something happened in the factory, Geng Zhiyuan couldn't help but want to go and see what was going on. After saying hello to He Fengwen, he opened his legs and hurriedly walked towards the fertilizer factory.

The gate of the fertilizer plant was closed, and the door was densely packed with people. A young woman wearing a white belt and filial piety knelt on the ground with a three- or four-year-old child in her arms and cried, and several relatives were constantly persuading her. Behind him were several banners with black letters and white backgrounds, which were written in bold and bold words such as shouting grievances.

Geng Zhiyuan was looking at it with affection, and suddenly someone stabbed him lightly and whispered in his ear: "Geng Gong, why are you here?"

Geng Zhiyuan turned his head to look, and behind him was Sun Daqi, the director of the nitric acid workshop of the fertilizer plant!

"Huh, Director Sun?" Suddenly seeing an old friend, Geng Zhiyuan hurriedly shook hands with him and said, "Oh, I haven't seen you for several years." ”

"Don't call me Director Sun. Sun Daqi smiled bitterly: "I am no longer a director, I have been dismissed and laid off." ”

"Why are you laid off?" Sun Daqi is slightly older than Geng Zhiyuan, just when he is in the prime of life, he is still a middle-level cadre in the factory, how can he be laid off?

Sun Daqi sighed and said: "Director Chen is gone, and our group of people who follow him to do practical things can still be accommodated in the factory?

"And ...... you now?"

Sun Daqi's face darkened and said: "As a squad leader in a small factory, I earn food to eat, and I can't starve to death." ”

"That's a shame. Geng Zhiyuan said regretfully: "You are an expert in the normal pressure method and the medium pressure method of nitric acid, and it is too short-sighted for the factory to drive you away like this, right?"

"Alas!" Sun Daqi sighed: "If I were still here, how could I let Liu Dazi give away his life this time." ”

Liu Dazi is Liu Xiaowen's nickname, and he is the most capable squad leader in the nitric acid workshop, and he can deal with general mechanical and electrical failures. Geng Zhiyuan had dealt with him a few times, and he was quite familiar with him.

"What's the matter?" said Geng Zhiyuan, who had an accident.

"Yes, that's him. Sun Daqi told the story in detail, and Geng Zhiyuan learned the truth.

After the county fertilizer plant downsized, the output was calculated by shift, and bonuses were issued according to the output. The night before yesterday, it happened that Liu Xiaowen's team was on night duty, and not long after taking over, the dilute nitric acid pump leaked.

It stands to reason that in this case, the pump should be stopped for maintenance, and the backup pump should be turned on at the same time to maintain continuous production. However, the backup pump has long been damaged and has not been returned to the manufacturer for repair. At this time, if the dilute nitric acid pump is serviced, the dilute nitric acid sent to the concentrated nitric acid plant will be stopped, resulting in the shutdown of the entire concentrated nitric acid plant.

The shutdown of the plant will not only affect the efficiency of the workshop, but also lead to the cancellation of the bonus of the shift team. In order not to be deducted from his bonus and salary, Liu Xiaowen put on a gas mask and forcibly overhauled the dilute nitric acid pump during operation.

Although the fault was eliminated, Liu Xiaowen inevitably inhaled a large amount of nitrogen oxide gas and acid mist during the maintenance process, which could not be completely isolated even if he wore a gas mask.

After returning to the office, Liu Xiaowen felt unwell, drank a large glass of condensed milk, and soon began to vomit blood. Colleagues rushed him to the hospital, where the emergency doctor said that his lungs had been almost completely eroded to the point of erosion, and he died of pain not long after.

Because Liu Xiaowen violated the operating procedures and caused his own injuries, the factory refused to recognize him as a work-related injury. In the end, the family members were forced to come to the factory gate to block the door and shout grievances.

"Lost your life for a bonus of twenty or thirty yuan, do you think it's worth it?" Sun Daqi said indignantly.

Geng Zhiyuan secretly said that it was a pity, and Sun Daqi said again: "It doesn't matter if he dies, leaving his wife and three-year-old child, his wife has no job yet." You say, how will they live in the future?"

Geng Zhiyuan sighed, counted out a thousand yuan from his wallet and said, "Once you get acquainted, you have to do some favors." You helped me give this thousand yuan to his daughter-in-law, which is a little bit of my heart. ”

"Oh, what's so embarrassing about this? How can I make you pay for it?" Sun Daqi looked at the money that was shoehorned in his hand, and said with some emotion.

"Take it. Geng Zhiyuan couldn't bear to look at it any longer, turned around and said, "I'm leaving." Old grandson, take care of yourself!"

"Thank you!" Sun Daqi looked at his lonely back in the distance, and said to himself: "Geng Gong is really a good person, I don't know if I will have the opportunity to meet him again in the future." ”
