High-efficiency static electricity dust removal device based on electrification-by-friction principle of differential hairbrushs

Abstract

The invention relates to a high-efficiency static electricity dust removal device based on the electrification-by-friction principle of differential hairbrushes. The high-efficiency static electricitydust removal device based on the electrification-by-friction principle of the differential hairbrushes mainly comprises a box, a grid plate, a motor, a center shaft, a draught fan shell, a draught fan, an electromagnetic clutch, a push-pull type dust collection tank, an annular metal net, a flat key, a fibrous membrane, the hairbrushes and a filtration component, wherein the fibrous membrane withthe bulged soft hairbrushes is arranged on the annular metal net; the hairbrushes are in contact with the surface of the first layer of electrospinning fibrous membrane of the filtration component tocause mutual friction, thereby enabling the contact surface to generate charge transfer and generating static electricity; the electromagnetic clutch is arranged between the draught fan and the annular metal net, so that the intermittent friction is generated between the hairbrushes and the filtration component, and the charge neutralization time of the fibrous membrane with the bulged soft hairbrushes and the filtration component is delayed; the membrane loss is reduced; and the electrified durability is improved. The high-efficiency static electricity dust removal device based on the electrification-by-friction principle of the differential hairbrushes has the beneficial effects that the filtration component has a good charge performance and a filtration performance on the whole; the fibers can be degraded and are green and environmentally-friendly; the static electricity dust removal is carried out by autoexcitation friction; the energy consumption and equipment cost can be obviously reduced; and the device is simple and convenient, has extra small volume and can save indoor space.

Description

Technical field [0001] The invention relates to a high-efficiency electrostatic dust removal device based on the principle of differential brush friction electrification, and belongs to the technical field of air purification. Background technique [0002] Air pollution is becoming more and more serious, and air pollutants have shown new characteristics: the proportion of fine particulate pollutants in the air has increased, and the compound pollution of the atmosphere has increased. Therefore, it is of great significance to develop an effective air purification device. [0003] At present, indoor air purification methods at home and abroad mainly include electrostatic dust removal method, wet dust removal method, adsorption purification method and low temperature plasma method. However, using the above technology alone generally has problems such as poor effect, high energy consumption, and easy clogging. Among them, wet dust removal has high cost and difficult maintenance; low-...

AI Technical Summary

Problems solved by technology

However, there are generally problems such as poor effect, high energy consumption, and easy blockage when using the above technologies alone.

Among them, the wet dust removal cost is high and maintenance is difficult; the low temperature plasma method is easy to generate ozone and form secondary pollution

Electret electrostatic dust removal has problems such as short-term static residence and electrostatic loss; the effect of electret is greatly affected by temperature and humidity, and the filtration effect is unstable; a large amount of dust accumulation on the surface of the filter membrane increases the filtration pressure loss, resulting in energy loss. High consumption, short membrane life
