Sintering flue gas cloud dynamic atomization desulfurization and white elimination technology has solved the technical problems of low resistance wet desulfurization and condensation white elimination of sintering machine, and the first construction project has been successful, and the steel production capacity of Liugang has increased by 800,000 tons/year after completion.

Problems in flue gas ammonia desulphurization system of a steel 110m2 sintering machine

1, the flue gas flow rate is too large;

2, particulate matter emissions exceed the standard;

3, smoke into the tower smoke temperature is high;

4. Escaping ammonia is easy to form high particles and water vapor in the flue gas

Concentration aerosol, smoke trailing and crystal rain phenomenon are serious;

5, the flow field and temperature field in the tower are uneven, and the desulfurization efficiency is low;

6, the slurry oxidation effect is poor;

Innovative technology and characteristics of desulfurization and whitening in Wuhan P&G

1, low wind resistance cloud dynamic swirl atomization and condensation technology;

2, slurry deep cooling smoke temperature control technology;

3, low wind resistance fog removal and condensation combined tower breaking technology;

4, condensing high-efficiency tube bundle and scraper type fog removal technology;

5. Anti-clogging composite packing technology with both cooling and wet film adhesion;

6, ultra-low temperature cooling water technology;

7, thick slurry thiamine and mineral powder double recovery integrated sludge treatment technology;

8, smoke cyclone flow field technology;

9, efficient multi-channel fog removal technology;

10, composite screen fog removal technology;

11. The flue gas resistance of the system formed by the overall process is low, which is of great help to the improvement of sintering capacity and the reduction of operation energy consumption.

12, the environmental protection effect is outstanding, to ensure the exhaust "three" (no acid rain, no white smoke, no aerosol).

13, Liusteel ammonia desulfurization and ammonium sulfide preparation process is the most familiar, desulfurization process details are good, the overall process is more complete.

14, the emission indicators fully meet the ultra-net emission standards, and have a larger richness.
