Desulfurizing tower is installed on the ground, comprises tower tube 11, the built-in spray equipment of tower tube, and the tower tube is provided with into mouth 13, outlet flue 14, doctor solution import 15 and scavenge port 12.Advance mouth 13 and outlet flue 14 and lay respectively at the bottom and the top of desulfurizing tower with the form of pipeline, doctor solution import 15 and scavenge port 12 lay respectively at the top and the bottom of desulfurizing tower, advance mouth and link to each other with boiler flue, and these are the essential structure of desulfurizing tower.
Spray equipment is positioned at tower tube internal upper part, constitute by uniform nozzle array, adopt the mode desulfurization of water curtain, and the water inlet of spray equipment communicates with the doctor solution import, serial connection one kinetic pump in the middle of both, this kinetic pump is transported to the liquid in the doctor solution liquid storage tank in the tower tube, and the liquid in the doctor solution liquid storage tank preferentially adopts the industrial wastewater of this enterprise.
Doctor solution liquid storage tank 5 is connected with desulfurizing tower scavenge port 12 with the U-shaped pipe 22 of demist duct bottom respectively, and doctor solution import 15 is connected to doctor solution liquid storage tank 5 through pump 6, forms a closed circulation, and waste water absorbs sulfur in smoke, and can be recycled.
The circulating path of doctor solution is: doctor solution liquid storage tank → doctor solution import → spray equipment → tower tube inner chamber → scavenge port → doctor solution liquid storage tank.
A small amount of cooling sweetening liq of collecting in the pipe of demist simultaneously also is back to the doctor solution liquid storage tank
In the tower tube, doctor solution falls from top to bottom, drives in the wrong direction with the boiler smoke that rises from bottom to top, and chemical reaction takes place.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
