Centrifugal wind wheel and air treatment device with same

Abstract

Disclosed are a centrifugal wind wheel and an air treatment device with the same. The centrifugal wind wheel comprises a base plate, a motor mounting hole, blades and a reinforcing frame or wheel cover, one ends of the blades are distributed on the base plate at certain intervals along a peripheral direction, the other ends of the blades are fixed on the reinforcing frame or wheel cover along the peripheral direction, the blades comprise a first group of blades and a second group of blades, both the two groups of blades have conduction characteristics, and the first group of blades and the second group of blades are distributed in a mutually staggered manner, are insulated from each other and are not conducted; and high potential and low potential are respectively applied to the first group of blades and the second group of blades, a high-voltage charging place is formed between the first group of blades and the second group of blades which are staggered mutually and forms a dust removal channel, and the dust removal channel can effectively absorb dust particles in airflow flowing through the dust removal channel. The centrifugal wind wheel and the air treatment device with the same have the advantages of simple and reasonable structure, high dust absorption efficiency, low resistance, electricity consumption and noise and zero pressure loss.

Description

technical field [0001] The invention relates to a centrifugal wind wheel, in particular to a centrifugal wind wheel capable of reducing the concentration of indoor dust particles and an air treatment device with the centrifugal wind wheel. Background technique [0002] With the development of industrial production and the increase in the use of automobiles, the dust in the atmosphere has increased, and the air pollution has intensified. With the intensification of outdoor air pollution, the dust in the indoor air has also increased. On the other hand, with the improvement of people's living standards, consumers have put forward strict requirements for the purification of indoor air. Relevant national departments have also strengthened the detection of PM2.5 dust particles. However, the current traditional air purification device mainly passes through a dense black handkerchief HEPA filter with a thickness greater than 30 mm. When the dust in the air flow passes through the ...

AI Technical Summary

Problems solved by technology

The filtration efficiency of the filter screen in the filter device of this structure decreases significantly with the increase of the use time; in addition, the filter screen is easy to block and needs to be replaced frequently; due to the large thickness and large resistance of the filter screen, the pressure drop after the air passes through the filter Generally, it is more than 50-100 Pa, which leads to the disadvantages of heavy load on the motor and fan equipment in the purification device used with the filter, large motor power, high power consumption and high noise.

[0003] In addition, the traditional centrifugal wind wheel only has the characteristics of pressurized air supply, and does not have the functions of dust adsorption and dust removal
