Cross-flow wind wheel and air treatment device with cross-flow wind wheel

Abstract

The invention relates to a cross flow wind wheel which comprises shafts, shaft sleeves and blades; the blades are arranged to be a circular shape at intervals along a circumferential direction; both ends of the blades are provided with left end plates and right end plates for fixing the blades; the shafts and the shaft sleeves are respectively arranged on the left end plates and the right end plates; the middle parts of the blades are provided with more than one middle division board capable of reinforcing the rigidity of the blades; the blades comprise a plurality of groups of first blades and second blades, which can be connected with high-voltage power supplies and are conductive; the potentials of the two groups of blades are different, and the two groups of blades are mutually staggered and are not communicated; and a high-voltage dust removal channel which can absorb micro particles which flow through the airflow in the channel is formed between the two groups of blades. An air treatment device with the cross flow wind wheel comprises a shell body which consists of a volute casing and a volute tongue and the cross flow wind wheel; the cross flow wind wheel is connected into the shell body through the rotation of a motor; and the air treatment device also comprises a corona discharge device which can enable the micro particles in the airflow to be charged or a negative ion emission ionization device, and is connected with the high-voltage power supply. The invention has the characteristics of simple and reasonable structure, high dust collection efficiency, small resistance, low power consumption, low noise and no pressure loss.

Description

technical field [0001] The invention relates to a cross-flow wind wheel and an air treatment device with the cross-flow 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 tiny particles of PM2.5. [0003] At present, the traditional air purification device mainly passes through a dense black handkerchief HEPA filter with a thickness greater than 30 mm. When passing through the dense filter, the tiny particles in the air flow are blocked by the filter and thus absorbed. For example, Chinese Patent Do...

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.

[0004] In addition, the traditional cross-flow wind wheel only has the characteristics of pressurized air supply, and does not have the function of micro adsorption and dust removal
