Wet dust collector

Abstract

The invention relates to the field of dust collectors and particularly discloses a wet dust collector. An overflow pipe is connected between a dust collection tower and a dust collection reservoir of the wet dust collector, a washing main pipe is arranged above a dust collection air pipe, a plurality of washing branch pipes are distributed on the washing main pipe, and each washing branch pipe is inserted into the pipe wall of the dust collection air pipe through inclined-angle holes. The wet dust collector ensures that water level in the dust collection tower is not higher than the normal water level through the overflow pipe, enables dust collection air amount of the wet dust collector and outlet dust content to be reduced to be stabilized at the preset level, simultaneously avoids plugging by washing the dust collection air pipe in rotating washing mode through a washing mechanism, and can ensure good dust collection effect.

Description

technical field [0001] The invention relates to the field of dust collectors, in particular to a wet dust collector. Background technique [0002] Wet dust collector is a device that uses the action of water or other liquids and dust-containing gas to remove dust. When dust particles meet sprayed water droplets, water films or wet arms and devices, processes such as wetting, condensation, diffusion and settlement occur. Therefore, the dust particles are separated from the gas to achieve the purpose of purification. The wet dust collector has the advantages of low investment, simple operation, small footprint, and can purify harmful gas, cool and humidify dusty gas at the same time. It has been widely used in air pollution control and gas purification in various departments of industrial production. . For example, many iron and steel companies have adopted wet dust collectors to remove dust from the quicklime dust in the batching room of the sintering plant. [0003] There...

AI Technical Summary

Problems solved by technology

[0003] There are also certain defects in the existing wet dust collectors: for example, the direct connection between the dust removal tower and the dust removal reservoir is through pipes, which is not conducive to stabilizing the water level of the dust removal tower, and ultimately affects performance indicators such as dust removal air volume and outlet dust content; The dust removal air duct is easy to block, which affects the dust removal effect, and the setting makes the wet dust collector not work normally; for example, the sewage has not been effectively recycled, resulting in excessive consumption of clean water; etc.
