Electrostatic water washing dust removing apparatus

Abstract

The invention relates to an electrostatic water washing dust removing apparatus, which comprises a housing, wherein the housing is provided with a gas inlet pipe and a gas exhaust pipe, a liquid phase labyrinth is arranged inside the housing, the gas inlet of the liquid phase labyrinth is communicated with the gas inlet pipe, the gas outlet is communicated with the gas exhaust pipe, at least the partial liquid phase labyrinth is immersed in a liquid, the liquid phase labyrinth is formed by straggeredly arranging a plurality of horizontally arranged separation plates, at least the facing-water surfaces of the separation plates are provided with a bristle layer, the upper portion of the liquid phase labyrinth gas inlet is provided with a negative ion device, the discharge electrode in the negative ion device is connected with the positive electrode of a power supply, and the liquid phase labyrinth is an electric conduction body and is connected with the negative electrode of the power supply or the ground. According to the present invention, the wet absorption way is used and the liquid phase labyrinth structure is matched, such that the dust in the air is effectively absorbed, and the indoor absorbable particles are reduced; and particularly the liquid phase labyrinth structure is used so as to prolong the contact time of the air and the liquid, and the negative ion device structure is matched so as to well adsorb the particles into the liquid, such that the dust removing effect is improved.

Description

technical field [0001] The invention relates to the field of dust removal and haze prevention, in particular to an electrostatic water washing dust removal device. Background technique [0002] In dusty weather conditions, such as haze weather, there is often a lot of dust indoors, which affects people's respiratory health, especially in tall buildings. [0003] Existing air purifiers mostly use filtration to remove dust. The problem is that this kind of filter is difficult to filter small particles of dust, such as small particles of PM2.5 and below, which will still enter the human body. accumulation in the lungs, seriously affecting the health of the body. The use of more precise filters can filter fine particles, but this also creates new technical problems. More precise filters are easily blocked by dust or fine particles, and the cost of frequent filter replacement is high. The tablets cannot be recycled, causing new environmental pollution. [0004] The use of filt...

Problems solved by technology

[0003] Existing air purifiers mostly use filtration to remove dust. The problem is that it is difficult for this kind of filter to filter small particles of dust, such as small particles of pm2.5 and below, which will still enter the human body. Accumulated in the lungs, seriously affecting the health

The use of more precise filters can filter fine particles, but this also creates new technical problems. More precise filters are easily blocked by dust or fine particles, and the cost of frequent replacement of filters is higher, and the replacement of filters Tablets cannot be recycled, causing new environmental pollution

[0004] The use of filters, especially more precise filters, gradually increases the wind resistance over time, resulting in higher energy consumption or lower ventilation efficiency
