The invention has the following advantages and positive effects:
1. the invention has the advantages of simple and reasonable structure, convenient operation and use, small occupied area and low operation cost due to the adoption of the structure, and particularly, the dust removal device has better dust removal effect due to the adoption of the double-layer white steel mesh cloth filter barrel.
2. In the invention, the flue gas with slurry fog drops and dust is blown to the slurry D by a fan through a flue gas inlet pipe, the flue gas is contacted with alkaline limestone slurry fog drops sprayed from top to bottom, and the acidic oxide SO is contained in the flue gas2Other pollutants HCL, HF and the like are absorbed, so that the flue gas is fully purified; absorption of SO2The slurry is reacted to generate CaSO3In-situ forced oxidation and crystallization to form CaSO4•2H2And O, dehydrating to obtain a commercial grade desulfurization byproduct, namely gypsum, and finally realizing the comprehensive treatment of the sulfur-containing flue gas.
3. The invention sprays smoke with dust through a first spray header to form a smoke dust mixture with slurry fog drops, the smoke dust mixture with the slurry fog drops is blown to slurry D through a fan to be firstly purified, is turned back and then is sprayed through a second spray header arranged in a chamber A, so that redundant smoke dust is mixed with the slurry again, enters the slurry D in a chamber B after being mixed, is filtered through a double-layer white steel mesh cloth filter barrel arranged above the chamber B after being turned back to obtain third purification, and then is sprayed through a third spray header and a fourth spray header, and clean smoke is discharged from a smoke outlet, so that the dust removal is thorough and the effect is good.
