Aside from the lengthy research process, it is directly from the conclusion

Advantages of both:

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

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

Disadvantages of both:

Dry desulfurization is expensive.

Wet desulfurization, wastewater.

Therefore, the result was very clear. Wastewater was not my business, but it affected my livelihood.

Therefore, due to the price disadvantage of dry desulfurization, wet desulfurization accounts for an absolute majority, and the same is true in the international community. If you have to say it, choosing a desulfurization method is definitely not so reckless. It must be determined based on coal types, preparation supply, by-product utilization, and other factors including geography, environment, climate, etc.

What Chang Siping conquered this time was the "lime-gypsum method" with the highest popularity in wet desulfurization. The flue gas sprayed out from the boiler. First, it must be baptized by deammonia equipment and electro-dust removal. Those non-mainstream pollution can be brought into the ash delivery pipe, and the mainstream flue gas will then enter the desulfurization equipment to react in it. Due to the intervention of h2o (water), this process is more efficient and requires less preparations. In addition to calcium sulfate, the final product also includes a large amount of gypsum. If there is demand in the market and the transportation costs are reasonable, the gypsum can be sold or thrown away without feeling distressed.

So gypsum is always very cheap!

To put it simply, in fact, dozens of equipment are needed in this process. This time, Zhang Yifu also requires monitoring functions, which involves the matter of microcomputer automation. In addition, an interface with the Constant Electric Automation system is required to complete the great cause of Constant Electric Automation.

Research and development from scratch will be a huge and complicated project. Therefore, most companies in this area have directly introduced foreign technology in their previous lives. Although Hengdian did not introduce it, Zhang Yifu himself is equivalent to living technology. All equipment with too high requirements will inevitably be introduced from abroad. Judging from the current report, Siemens can meet all needs. Of course, other companies, including Mitsubishi, have done better, which is a problem in the future optimization stage.

Due to the restrictions on the office development conditions of the second repair factory and the requirements of the "Jijing Air Pollution XXXX Regulations", Chang Siping's team found it difficult for him to conduct the next test in Beijing. He could only continue to carry out component production and research and development, theoretical calculations, etc., and was even connected with Changjiang's working group to automate. Therefore, the factory in northern Jilin must be completed as soon as possible. They can produce a complete set of products, assemble and test, and manufacture tons of gypsum.

It can be said that the theoretical research stage is easier than Zhang Yifu expected. Professor Chang Siping's level is not ordinary. After a period of time, he started working. He was like a laid-off worker re-employed, cherishing, motivating, and working very hard. Now he has entered the stage of production testing. They need a platform, which is a hurry, delaying the construction of a factory for one day, and delaying the making of money for one day.

The train entered the station and the welcome lineup was beyond Zhang Yifu's expectations.

Although it surrounds Jijing City, Hebei Province has never been a wealthy province. There is coal in the west, there are people in the south, there are sea in the east, and there is a great capital in the middle. It is like a hardworking elder sister who always nurtures the capital. But she has never asked for anything, and is honest and dedicated. Now the capital has thrown heavy industry and heavy pollution over again, and she has to obey the central government. Beautiful and beautiful and bright.

This time it was not a bad thing. As for northern Hebei, there seems to be not much to be found except for the power plant and donkey meat. A considerable number of GDP are supported by the power plant. They also hope that a factory with excellent efficiency will be settled 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. Therefore, the local government has almost all come from mayors, secretarys, and directors of various offices to form a welcome team of more than ten people, so that this entrepreneur can feel the enthusiasm of our people in northern Hebei.

Zhang Yifu was stunned as soon as he got off the train. This scene was almost over the inspection by the central leaders, and even arranged for a class of elementary school students to come forward to deliver flowers in school uniforms.

Although the little girl who sent the flowers smiled, her expression was very nervous. She seemed to be performed. She jumped to Zhang Yifu according to the leader's instructions, holding a bouquet of flowers in her hands: "Welcome Uncle Zhang to settle down in Jibei!"

"Thank you, I wish you study hard and improve every day." Zhang Yifu bowed and took the bouquet.

Soon, the few people accompanying him were treated similarly.

Everyone held the bouquet and did feel the enthusiasm of northern Hebei, but they also felt a little embarrassed. What kind of virtue do they have to let the children in class give up their studies and wait here for an hour to deliver flowers to themselves?

Several leaders came up and shook hands with the Hengdian team one by one to introduce them.

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

However, his appearance and temperament have nothing to do with Brother Fa. He is more like Niu Dameng, a dark man. He speaks very routinely, looks rough and chats in detail.

Surprisingly, Zhang Yifu found the old brother behind the welcoming team.

"Xiaozhuang?" Zhang Yifu saw Niu Xiaozhuang silently behind the team from afar. This guy has a little more beard and fatter, which is closer to the "orangutan" that Xia Xue knows. However, he now has a bit more mature smell, which is also the smell that a father should have.

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

"What do you care about?"

The two laughed and hugged each other. The hug was still the same as the old feeling, and they were so angry!

Seeing this, Mayor Zhou Zhou also smiled and said, "Didn't you hear that Mr. Zhang had worked in our Hebei Power Plant before? I've been bothered by the comrades from the power plant to come."

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

"Yes, go to a place to talk first."

Everyone got on the bus while chatting and laughing, and headed straight to the Jibei Hotel.

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

In less than five years, Jijing can be said to be changing with each passing day and has changed a lot. Every day, high-rise buildings are built, old houses are disappearing every day, roads are widening, cars are increasing, and people are becoming more beautiful. But when I come to northern Jilin again, I see the changes that are pitifully small. Even the snack stalls outside the train station are still the boss and that guy.

If you don’t say anything, places like Baozhou, Shijiazhuang, and Lingfang in Hebei Province may change more, or even Chengde. Perhaps they will be built because of tourism profits, but northern Hebei really has no opportunity. They are closer to Inner Mongolia, there is no large industry, and no one will come here specifically to eat donkey meat. They really have limited livelihoods.

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

Because northern Hebei is never a good place for enterprises to settle down. First, it is a certain distance from the expressway, which is a shortcoming for logistics; second, the economy is not good. Talents are unwilling to come, and they cannot be kept even if they come; third, the environment is not very pleasant; fourth, the current economy has completed the transfer from the northeast to the southeast, and building factories in some places to the south will make the supply chain more comfortable.

As Zhang Yifu himself, it is almost the first time that he has made such a "imperfect" choice that seems hasty.

He actually didn't think so much, he just wanted to give back to this city or the countryside.

On the other hand, the Hebei government attaches great importance to it. It is also hoped that this may be the only opportunity to retain this company.

In the car, the mayor spared no effort to talk about the plan for northern Hebei. What will be the expressway within a few years, and the school and hospitals are following the construction, and they always want to add some points to northern Hebei.

Of course, Zhang Yifu would not pour cold water on him. After showing similar amazement and expectations, he also began to brag about several major projects of Hengdian. This time, the environmental protection factory has unlimited opportunities. If it is completed, it will definitely drive the economic development of the entire northern Hebei region and employment will be deeper.

There is no way. People who are not so familiar with this kind of conversation are trying every means to raise their own value. Zhang Yifu seems low-key and is not as good as the class.

When they entered the hotel, Zhang Yifu and his party went to the room to rest, while people from northern Hebei arranged in the banquet hall.

Niu Xiaozhuang and Zhang Yifu came to the room, and when he entered the room, he became anxious first.

"Fuck! There are such rooms in Jibei Hotel?" Niu Xiaozhuang was so angry. A large suite with a small size of 200 square meters, with international standards. Why does Jibei still have such existence? "This must be used to welcome big people. The presidential suite is just like this? Is it hoped that the president and the prime minister and other big leaders will come one day, but you will get a bargain!"

"It's really true." Zhang Yifu was not surprised. This room is quite luxurious, but in fact it's a bit inferior to Kunming's room. It's just that Niu Xiaozhuang has never seen the world. "If our factory really settled here, maybe the Prime Minister will come one day."

"Just brag." Niu Xiaozhuang laughed and said with a smile, "Then I have to wait for my dad to become the prime minister, right? I just heard you and the mayor brag in the car, and I got goosebumps all over my body."

"It's rare and strange." Zhang Yifu also smiled and cursed, put down his luggage and walked into the bathroom. "I feel uncomfortable on the train, so I'll wash my face first."

Niu Xiaozhuang was not seen, but leaned against the bathroom door to chat.

"How are your child?"

"That's so good. When you finish your work, you'll go and see it. It runs faster than you." Niu Xiaozhuang smiled happily, "Originally, I wanted to have another one, but my father refused to let me go, saying that unless I don't want to be a cadre."

"Forget it, the discipline is here. You are a power plant leader, so how can you take the lead in over-birth?" Zhang Yifu also advised him Uncle Niu.

"Why don't you allow me to support me?" Niu Xiaozhuang still disagreed. "Besides, if you don't become a cadre, you won't be a cadre. I'll just ask you for it?"

"Private enterprises also have discipline. Family planning is a national policy. If someone has more than one child, all aspects will be under pressure." Zhang Yifu continued to help him Uncle Niu.

"If we have a relationship, you will get me away if you give me some pressure?"

"That's a big deal. I don't even open your nose when the Prime Minister pointed at me. Your son is also my son!"

"What you said, why does it sound so awkward to me!"

"Haha." Zhang Yifu wiped his face with a towel and laughed, "To be honest, if you want to have one more, you can use legal means to live in the next life, which is a little more trouble."

"How to give birth?"
