Dust purifying assisting device and dust purifying system and method

Abstract

The invention relates to a dust purifying assisting device and a dust purifying system and method. The assisting device comprises an accommodating cavity and an air supply device, wherein the accommodating cavity is suitable for being communicated with a dust purifier and is used for accommodating an adsorbent; the air supply device is communicated with the accommodating cavity and is used for supplying airflow to the accommodating cavity; and the adsorbent can be driven by the airflow to be mixed with to-be-purified dust-containing gas. The dust purifying system comprises the dust purifier and the dust purifying assisting device, wherein the dust purifying assisting device is communicated with the dust purifier; and dust-containing gas and adsorbent-containing airflow are mixed and then are purified by virtue of the dust purifier. According to the dust purifying assisting device and the dust purifying system, the adsorption effect of a filtering part of the purifier is improved, the back-flushing dust cleaning operation is promoted, fine dust can be relatively easily collected, the service life of a filter element is prolonged, the cost is saved, and the influence caused by the dust to the environment and air is further reduced or avoided.

Description

technical field [0001] The application of the present invention belongs to the technical field of dust removal devices, and relates to a dust purification auxiliary device, a dust purification system including the dust purification auxiliary device, a dust purification auxiliary method and a dust removal method thereof. More specifically, it relates to a purification auxiliary device for a large amount of fine dust generated by laser or mechanical scribing in the semiconductor and solar cell manufacturing industries, a purification system including the auxiliary device, and a corresponding method. Background technique [0002] In recent years, thin-film solar technology has emerged. Since thin-film solar cells have the advantages of light weight, low cost, and easy installation, they have developed rapidly once they were proposed. Specifically, copper indium gallium selenide thin film solar cells have become the most promising thin film photovoltaic devices due to their hig...

AI Technical Summary

Problems solved by technology

[0005] Common dust purifiers in the prior art are usually composed of three parts: fan, filter device and dust collection device. The dust purifier mainly blows the dust on the surface of the substrate again through the fan or auxiliary blowing mechanism to help the dust collection hood or The filter system is adsorbed, and its specific structure and control system are relatively complicated

Although the filter element or filter device therein can effectively filter most of the fine dust, there are also fine dust with smaller particle sizes that block the filter holes or adhere to the filter element and are not easy to fall off, resulting in the cost of frequent replacement of the filter element; in addition , fine dust easily floats in the air and pollutes the workshop environment and air
