Energy-saving wet type dust collector

Abstract

The invention provides an energy-saving wet type dust collector. The energy-saving wet type dust collector comprises a dust chamber, the upper end of the dust chamber is provided with an air inlet, a narrow air passage which is vertically and downwardly communicated with the dust chamber is formed in the air inlet and downwardly faces a rhombic block fixed in the dust chamber, and the narrow air passage is laterally and vertically communicated with capillary tubes which are communicated to a water tank with a water level lower than a port of the narrow air passage. The upper portion of the dust chamber is laterally provided with an air outlet, the lower end of the dust chamber is connected with a water drain pipe which forms a water-sealed joint below the dust chamber, and water seal can be formed in the water-sealed joint. The energy-saving wet type dust collector has the advantages that small dust particles in dusty air can be removed by a small amount of water, excellent energy saving effect is achieved, and dedusting cost can be remarkably reduced.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to a wet dust collector. Background technique [0002] Industrial dust collector is one of the basic environmental protection equipment, mainly used to remove particulate matter in dusty gas. The current dust collectors mainly include dry dust collectors and wet dust collectors; among them, dry dust collectors include cyclone dust collectors, electrostatic precipitators, bag dust collectors, etc.; considering production costs, bag dust collectors The most widely used; however, because baghouses filter dust particles through filter cloths, they do not filter well for smaller particles. The wet dust collector can remove smaller particles; the basic principle is to use the spray head to spray the inside of the filter tower on a large scale, so that the dense water mist will wrap the dust particles, so that the dust will be filtered from the filter along with the wat...

AI Technical Summary

Problems solved by technology

For this kind of wet dust collector, its biggest disadvantage is that a lot of water is wasted; because the distribution of dust particles in the gas is relatively sparse, each water column in the spray water can only touch a small amount of dust particles, which shows that its waste Extremely serious, resulting in huge energy consumption and cost of dust removal; and large-scale wastewater treatment is required, so the overall cost is high
