| Wet Desulphurization System |
 Desulphurization principle |
Changshu Hua Neng and the Dalian technical university passes through many years to cooperate the successful development hard law haze desulphurization, is one new aqueous method haze desulphurization craft, this craft obtained the obtained the expert group which the Ministry of Education organized to appraise the committee carrying unanimously.
The iron filings law haze desulphurization craft is one kind of resources absorption method haze desulphurization craft, this method in does not add under other catalyst conditions, the use clear water took the absorption fluid, add iron filings into the center of the absorption chamber, through the reaction between the iron filings and the acid , the hard ion initiation liquid phase catalyzed oxidation SO2 response occurrence which produces, during maintenance higher absorption fluid pH and desulphurization rate, obtains the highly concentrated ferrous sulfate solution by-product ,and may further oxidize into polymerization iron sulfate product. |

| Characters |
 Mainly use the waste iron filings as the raw material, which is quite rich in iron and steel enterprise, so-called it uses its resources. But the overseas technology has the region on the raw material
The wastage has the widespread market, it may serve as the waste water processing medicinal preparation, achieve the goal of waste governing the waste, also can have the certain economic efficiency
The entire technological process does not have two times of pollution, is a green technology |
| advantages |
 Invests few, which is only 1/3 of the overseas technical
The desulphurization rate is high, which is above 95%
running and maintenance cost are low
small area needed
automatist high and simple operation
short construction cycle
advanced craft, technology mature reliable, simple operation, maintains easily
The entire craft does not have two times of pollution productions |
| Application area |
| This craft is not only suitable to sintering, but also may apply in other profession waste gas the sulphur dioxide government, like metallurgy, chemical industry, electric power and so on |
| project example |
| No.4 Sintering of Wu Steel |
