A kind of flue gas dedusting method

Abstract

The invention relates to a smoke dust removal method. The smoke dust removal method comprises a shell (1), an air inlet pipe (3), an air outlet pipe (11), an overflow groove (6), an overflow plate (7), a liquid supplementing pipe (5), a rotating separation plate (8), a floating barrel (9), a rotating beam (10), a liquid inlet pipe (16), a liquid outlet pipe (17), a liquid inlet pipe control valve (18), a liquid outlet pipe control valve (19), a rotating separation plate contact (20), an overflow plate contact (21), a fog removal device (12), a fan blade (15), a motor (23) and a controller (22); the rotating separation plate rotates by virtue of the floating barrel on the lower part of the rotating separation plate and by virtue of floating force of absorption liquid, so that the distance between the rotating separation plate and the overflow plate is adjusted, and the circulation throughput of smoke is adjusted. By adopting the smoke dust removal method, the purifying efficiency of solid particles in gas can be improved.

Description

technical field [0001] The invention relates to a flue gas dust removal method. Background technique [0002] The dust removal mechanism of industrial dust removal methods in my country can be divided into two basic types: "dry type" and "wet type". Wet dust removal can be divided into various types according to the way of collecting dust: water bath, water film, impact type, Venturi tube and so on. Wet dedusting is to use water or other liquids to contact with dust-containing gas, and with the transfer of heat and mass, the dust particles in the dust gas are separated from the gas after washing. At present, the efficiency of the wet dust removal method is not high, generally around 60-90%, and the primary purification cannot meet the national emission standards. If the dust removal efficiency is further improved, the required pressure loss increases with the increase of efficiency, and the efficiency is not obvious, the gas throughput cannot be adjusted freely during dust...

AI Technical Summary

Problems solved by technology

At present, the efficiency of wet dust removal method is not high, generally around 60-90%, and one-time purification cannot meet the national emission standards

If the dust removal efficiency is further improved, the required pressure loss will increase with the increase of efficiency, and the efficiency is not obvious, the gas throughput cannot be adjusted freely during dust removal, and the solid particles adsorbed by the purification liquid are not easy to remove in the dust collector
