Chapter 484 Gypsum Flue Gas Desulfurization!
Chapter 484 Gypsum Flue Gas Desulfurization!
No more harmful substances?
Everyone was stunned, and then looked at each other.
Wang Ben touched his head and said suspiciously:
"Boy Su Yu, what kind of oxygen and sulfur are you so obedient, if you don't let him expel it, he won't expel it?
Su Yu chuckled: "It's just so obedient.
"what?"
This time, not only Wang Ben was stunned, but Lao Zhao and the others were also stunned.
Could it be, what special abilities does Su Yu have?
For this problem, in fact, Su Yu found a relatively complete solution under the prompt of the system as early as on his way home.
At that time, the first idea that appeared in his mind was to use de-"813" sulfur and denitrification coal.
In modern times, more than two thousand years later, the use of coal is still very extensive.
However, in terms of environment and air, it is much better than the previous hundreds of years.
The main reason, in addition to scientific management, is that the coal used is desulfurized coal.
Or the soot has been desulfurized.
There are many methods of coal desulfurization, but most of them require certain knowledge of modern physics and chemistry, and even the support of science and technology.
With the current technological level of Daqin, it is simply impossible to grasp.
However, coal desulfurization is difficult to achieve, but the flue dust desulfurization method is possible.
Among them, the gypsum flue gas desulfurization method is currently the most suitable flue gas desulfurization method in Daqin.
This method is relatively simple to operate and has high desulfurization efficiency.
It is also the main flue gas desulfurization method used by most modern thermal power stations.
The most important thing is that after the flue gas desulfurization is completed, a more useful substance will be produced.
The limestone powder is added with water to make a slurry, which is pumped into the absorption tower also built as an absorbent, and is fully contacted and mixed with the flue gas.
The sulfur dioxide in the flue gas is oxidized with the calcium carbonate in the slurry and the air blown from the lower part of the tower to form calcium sulfate.
When calcium sulfate reaches a certain saturation, it will crystallize to form dihydrate gypsum.
This dihydrate gypsum is also known as raw gypsum.
This is definitely a good thing.
Raw gypsum is calcined, ground and other processes to obtain B-type hemihydrate gypsum, namely building gypsum, also known as plaster of paris and plaster.
If the calcination temperature is 190C, model gypsum can be obtained, and its fineness and whiteness are higher than those of building gypsum.
If the raw gypsum is calcined at 400~500C or higher than 800C, the floor gypsum is obtained, and its coagulation and hardening are slow.
However, the strength, wear resistance and water resistance after hardening are better than ordinary building gypsum.
The most important thing is that even the most common gypsum has strong medicinal value.
Whether in the face of ordinary flu or major plagues, it can play a good role.
As long as the gypsum flue gas desulfurization is popularized, the air pollution problem can be solved.
And after treatment, the concentration of flue gas is also greatly reduced.
With the current ultra-high vegetation coverage in this world, it can be easily metabolized.
"Is this really possible?" Wang Ben widened his eyes, finding it difficult to understand the mysteries.
After all, the chemical conversion between substances is still somewhat mysterious to everyone present.
The only one of them understood Lao Zhao and couldn't help sighing: "The effect of this chemistry is really powerful.
"This is just the tip of the iceberg, and his strength is far more than that. Su Yu is also a little sighed.
For Su Yu's words, Lao Zhao agrees very much.
At the same time, after this time, he also began to ponder secretly in his heart.
It seems that Da Qin's efforts to promote the two natural disciplines of physics and chemistry should be greater.
At this moment, Zhang Liang suddenly raised his hand and said with a little hesitation: "Actually...I still have a question...
Su Yu looked at Zhang Liang: "Oh? Tell me.
Everyone also quieted down, and everyone's eyes were focused on Zhang Liang.
Although it is said that among them, Zhang Liang's age is very young.
But his point of view is always very tricky.
Always be able to hit the nail on the head.
This is true whether it is in military warfare or in national policy affairs.
"As far as I know, today's mechanical masters are developing some small-volume steam engines for use in the cars mentioned above. 99
"In addition to the fact that the trains will be put into use in the future, there is no way to install a cumbersome filter system for these mobile steam engines, right?
"Once the number of these steam engines increases, it will still cause such problems over time.
Everyone's heart skipped a beat.
Yeah, how did they forget about it?
Ever since Qiyu first proposed the concept of the car, it has been constantly improving.
Now it has come to an end.
In addition, railway transportation is also the key to the further development of Daqin in the future.
But now that this kind of problem suddenly occurs in the steam engine, Total 5.0 cannot put these two things on hold indefinitely.
Wouldn't that be too wasteful?
Faced with this question raised by Zhang Liang, Su Yu just said calmly:
"Tell them to continue to improve the transmission and other structures. I will solve the problem of the power source later."5
Seeing Su Yu's confident look, everyone's originally heavy hearts were relieved a lot.
Su Yu rarely promises anything, but once he does, it shows that he has great confidence in it.
Since he said so, there must be some solution.
I didn't say it now, it should just be that the time is not yet ripe.
