Guide blade or stator blade, and air treatment device having the same

Abstract

The invention relates to a guide blade or a stator blade, and an air treatment device having the guide blade or the stator blade. The guide blade or the stator blade comprises a wheel hub, blades and a wheel cover, wherein the blades are distributed on the wheel hub and / or the wheel cover at certain intervals along the circumferential direction. Structural characteristics of the guide blade or the stator blade are that: the blades comprise a first group of blades and a second groups of blades; the two groups of the blades have conductive properties; the first group of the blades and the second group of the blades are staggeredly distributed and insulated, and are not conducted; the first group of the blades and the second group of the blades are respectively applied with high potential and low potential so as to form a charged high voltage space between the first group of the blades and the second group of the blades, the high voltage space forms a dust removing channel, and the dust removing channel can effectively adsorb dust particles flowing through the dust removing channel. The blade and the device of the present invention have characteristics of simple and reasonable structure, high dust absorption efficiency, low resistance, low power consumption, low noise and no pressure loss. In addition, with the blade and the device of the present invention, air delivery, air pressure and efficiency of a fan can be effectively improved.

Description

technical field [0001] The invention relates to a guide vane or stationary vane, in particular to a guide vane or stationary vane capable of reducing the concentration of indoor dust particles and an air treatment device with the guide vane or stationary vane. 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 flo...

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, traditional guide vanes or stationary vanes only have the characteristics of changing the air inlet angle and increasing the static pressure of the air supply, but do not have the functions of dust adsorption and dust removal
