Dust collecting device applicable to machine room

Abstract

The invention discloses a dust collecting device applicable to a machine room. The dust collecting device comprises a shell, wherein an air inlet and an air outlet are formed in the shell; an exhaustfan, a polarizer and an electrostatic dust collector are sequentially arranged from the air inlet to the air outlet; the electrostatic dust collector comprises a frame, a positive plate and a negativeplate, wherein the positive plate and the negative plate are arranged on the inner side of the frame; the positive plate and the negative plate are arranged at an interval; a passage is left betweenthe two adjacent plates and is a bend passage; and insulation layers are coated on surfaces of the positive plate and the negative plate. The electrostatic dust collector is adopted for collecting dust, so that during work, dusty gas is electrically separated when passing through a high-voltage electrostatic field, dust is adsorbed on the plates, and a dust collecting effect is achieved; and withthe bend passage, an air filter path can be prolonged favorably, so that a dust collecting effect is better.

Description

technical field [0001] The invention relates to a dust removal device, in particular to a dust removal device suitable for a machine room. Background technique [0002] Electrostatic dust collection is a kind of gas dust removal method. The dust-containing gas is electrically separated when it passes through a high-voltage electrostatic field. After the dust particles and negative ions are combined with negative charges, they tend to discharge and deposit on the surface of the anode. A dust collection method that uses an electrostatic field to ionize the gas so that the dust particles are charged and adsorbed to the electrode. In the past, it was often used in coal-fueled factories and power stations to collect coal ash and dust in the flue gas. Now there are dust removal and sterilization products that can be used in households.

AI Technical Summary

Problems solved by technology

[0003] Existing computer rooms usually use exhaust devices to ventilate the air in the computer room, which has the effect of heat dissipation and cooling, but it cannot effectively filter the dust in the air, because dust is easy to accumulate on communication equipment and affects heat dissipation; some existing electrostatic dust removal equipment can be used It is used in the computer room, but due to the connection of high-voltage power supply, it is easy to cause static electricity accumulation, which poses a safety hazard, especially the ozone generated by high-voltage discharge will damage health, accelerate the aging of components, and the dust removal effect is not ideal, so there is an urgent need for a dust removal device suitable for the computer room
