For a moment, Niu Xiaozhuang was caught in the middle and didn't have much to say. In terms of friendship, he must have wanted to help Zhang Yifu, but he couldn't say too much to Qiu Ling. Even if his father came, it would be convenient to directly interfere with the department management. In theory, Zhang Yifu was indeed too arrogant. When the newcomer came, it was normal for him to be familiar with the power plant after reading the information for a few days, but he was arrogant and could not stand this boring job. It was wrong for Zhang Yifu.

"How about this." Qiu Ling raised his lips, "Call everyone in our department, draw a stack of information and ask a question, and you answered it. Even if you write it down, you can naturally move back to the office after you complete the task."

"As soon as possible." Zhang Yifu nodded directly.

"We have to say ugly words before." Qiu Ling added in a sinister voice, "If there are still things I can't remember clearly, I'm afraid I'll have to study in the information room for a while."

"Of course, please allow me to talk about ugly things ahead." Zhang Yifu stood up and said silently, "If I pass, I hope the section chief will not assign these tasks again. I respect the management of the leader and the individual leader. I hope the leader will also give me enough respect."

"What are you saying? When will I disrespect you?" Qiu Ling's face darkened and he quickly explained to Niu Xiaozhuang, "Xiaozhuang, this is Zhang Yifu's sensitiveness. I have always treated everyone equally."

"I understand, I understand." Niu Xiaozhuang frowned, "Yifu, you have figured it out."

"No problem." Zhang Yifu smiled and rushed to Li Weifeng who had been afraid to speak, "Weifeng, go and call Lao Wang and Sister Zhao over."

Li Weifeng looked at the section chief, and then set off after seeing Qiu Ling nodding.

Niu Xiaozhuang is here, and everyone from the technical department is here. The always deserted data room has become lively. Even the people from several offices around him are attracted. One passes to ten, ten passes to hundreds. In the end, even the office and production department are running here on the floor. Old friends Wen Tianming and Zhen Tian are also among them. Everyone surround the data room.

It doesn't matter to Qiu Ling. He expected that Zhang Yifu would fail. This kid should lose someone once and pay the price for his arrogance.

When everyone is here, the assessment begins.

"Old Wang, you go first." Qiu Lingchong said a little as he spoke, "Just pick it casually."

"Yeah." Old Wang was quite calm and did not forget to say to Zhang Yifu, "Yifu, technical matters are hard skills, no discussions, what information I got and what questions I asked for."

"No need to make things difficult, just be just."

So, Lao Wang walked to a cabinet with his hands behind his back, and without thinking much, he casually drew a stack of documents, turned a page casually, and asked:

"Well... this paragraph is about the water circulation system. Please briefly talk about it. Our factory has used several cooling water and scale prevention methods and briefly describe its principles."

After hearing this question, Zhang Yifu had not answered it yet, and the onlookers had already started to take action.

When a thermal power plant generates power, it requires heating a large amount of water, which generates steam to drive the impeller to rotate and generate electricity. When the steam completes the work, it naturally cannot be wasted. Most of them need to be re-incorporated into the water circulation system, which needs to be cooled, purified, and included in the boiler for heating again. In this process, due to the influence of temperature, pH value, trace elements, etc., scaling is inevitable in the cooling equipment and its pipelines. Because the water circulation in the power plant is huge, if there is no treatment measure, scale will accumulate very quickly. Perhaps in just a few days, the equipment will be scrapped and the pipelines will be blocked.

The question Lao Wang casually found was about scaling treatment. In power plant technology, it belongs to the relatively marginal category, and it is basically not mentioned in the textbooks of power systems.

Among the people present, only 30% of them could answer this question, but it is understandable that this is an office building after all. As for the three technical departments, it is probably only Lao Wang who is confident that he will answer this question without reading the information.

Lao Wang chose this question as unbiased and examined a not-so-simple basic concept.

But in the eyes of most people, it is unlikely that Zhang Yifu can answer perfectly.

It's very simple. Zhang Yifu may have read about this in school. Maybe Zhang Yifu is a top student and memorized all this part, but so what? Lao Wang's question was clearly stated. This time he asked not only the concept but also the reality. He had to answer what measures had been taken in the actual situation of the Jibei Power Plant. As for this question, it is impossible for him to answer accurately without the master of Jibei Power Plant.

Wen Tianming clenched his fists, and felt uneasy in his heart. He whispered to Zhen Tian next to him: "I have talked to Yifu. He knows a lot, really a lot... But he doesn't have time to understand this kind of problem yet."

"Let's just see." Zhen Tian looked on the sideliness, "I heard that Qiu Ling was deliberately trying to waste Zhang Yifu and asked him to watch things in the information room. When the newcomers come, they have to endure the job first. Only after impressing the leader will he send work. But Zhang Yifu couldn't bear it for a day and insisted that he had recorded it all. If he was so arrogant and had a scene, he would not blame others for being embarrassed?"

"That's what I said..." Wen Tianming said unwillingly, "But how could I write down so much information? I can't do it even if I give it a year."

These spectators have their own thoughts, and some people who understand technology have begun to answer questions secretly.

Zhang Yifu didn't think about it for too long and quickly replied: "The pollutant discharge method and internal treatment method were used."

When Qiu Ling heard this answer, he waved his hand immediately: "If you want to say it carefully, anyone can answer it in such a general way."

"If you are meticulous, you will have to endorse it."

"If you have the ability, just memorize it."

"Then stop me in time when you hear enough." Zhang Yifu coughed and started to do it clearly. "When the water source is sufficient, after the supplementary water is concentrated, if the carbonate hardness is lower than the limit carbonate hardness of the circulating cooling water, and the sewage can be fully utilized, the sewage discharge method is preferred. Since our factory is facing...... sewage can... so this method is mainly used, but considering the dry season and potential water shortage, our factory also has internal treatment methods and equipment at the time of design. In fact, it is also used when cleaning the equipment. This method is commonly used with acid additives... PH value is 7.2 to 7.8... Phosphate... Ethyldiaminetetramethylmethoxyphosphate... Negative divalent mercaptobenzothiazole......"

Before I knew it, three minutes had passed, and Zhang Yifu's mouth still showed no sign of stopping like a snoring. At the beginning, those words occasionally could be understood, but the more they were said, the more they were like the heavenly book. It didn't matter whether they were right or not. Even if they could instantly compile these magical words, it would be enough to make people worship it.

After about four and a half minutes, Zhang Yifu felt that he had finished speaking. He looked up and looked at his dull faces, scratched his head and asked, "Do you still need to continue? If you continue, it will involve the design drawings. It will take a long time to draw."
