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 problem

Embodiment 1

[0029] like figure 2 Among them, an electrostatic water washing and dust removal device includes a casing 17, and an air intake pipe 3 and an exhaust pipe 11 are arranged on the casing 17, and the air intake pipe 3 or the exhaust pipe 11 is connected with the fresh air blower 2; .

[0030] A liquid phase labyrinth 9 is provided in the housing 17, the air inlet of the liquid phase labyrinth 9 is communicated with the air intake pipe 3, and the air outlet is communicated with the exhaust pipe 11;

[0031] Said liquid phase labyrinth 9 is at least partially submerged in the liquid. With this structure, the exchange path between air and water is extended, and the dust removal effect is improved.

[0032] An optimized solution such as figure 2 Among them, the liquid phase labyrinth 9 is formed by a plurality of horizontally arranged partitions 91 staggered, and at least the water-facing surface of the partitions 91 is provided with a bristle layer 92 . With the bristle layers...

Embodiment 2

[0043] On the basis of Example 1, the further optimized structure is as figure 1 As shown in, a gas phase labyrinth 4 is also provided, the inlet of the gas phase labyrinth 4 is connected with the gas outlet of the liquid phase labyrinth 9, and the outlet of the gas phase labyrinth 4 is communicated with the exhaust pipe 11;

[0044] In the gas phase labyrinth 4, a plurality of horizontal partitions 42 are staggered to form a first-level labyrinth, and a plurality of vertical partitions 41 are staggered to form a second-level labyrinth. At least between the horizontal partitions 42 and the vertical partitions 41 An adsorption layer is provided on the windward side. This structure realizes the supplementary adsorption of particulate matter in the air, and at the same time helps to reduce the liquid droplets in the air, thereby reducing the humidity of the air outlet, and this structure also reduces wind resistance. The absorbent layer in this example can adopt the fabric with ...

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...
