a dust collector

Abstract

The invention relates to a deduster, which comprises a housing (1), an air inlet pipe (3), an air outlet pipe (11), overflow channels (6), overflow plates (7), liquid replenishing pipes (5), rotary separators (8), floating drums (9), rotary beams (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), rotary separator contact points (20), overflow plate contact points (21), a demister (12), fan blades (15), an electrical motor (23), and a controller (22). The rotary separators rotate depending on floating drums below the rotary separators and with the assistance of buoyancy of water, so that intervals between the rotary separators and overflow plates can be adjusted and a flue gas circulation treatment amount can be adjusted. The deduster is beneficial for improving the purification efficiency of gas.

Description

technical field

[0001] The invention relates to a wet dust collector. Background technique

[0002] my country's industrial dust collectors can be divided into two basic types: "dry type" and "wet type" according to the dust removal mechanism. Wet dust collectors are divided into various types according to the way of collecting dust: water bath, water film, impact type, Venturi tube and so on. The wet dust collector is a device that uses water or other liquids to contact each other with the 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 collector 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 will increase with the increase of efficiency, and the efficiency is not obvious, the gas throughput in the d...
