Filtration module capable of repeatedly desorbing and regenerating and production method thereof

Abstract

The invention relates to a filtration module capable of repeatedly desorbing and regenerating and a production method thereof. The filtration module is composed of a module shell and composite purification particles filled in the module shell; the module shell comprises a rectangular frame part formed by a U-shaped material frame, a rigid grid mesh, a reinforcing and supporting profile and a rivet welding machine fixing part; the enclosure space of the shell is filled with the composite purification particles. The production method comprises a process of producing the composite purification particles, a process of producing the module shell, a process of filling and a process of sealing. Compared with the prior art, the filtration module is capable of heating, desorbing and repeatedly regenerating; the service life is prolonged by more than ten times; the frequent replacement of the consumable material is obviously reduced; the purification efficiency is improved; the fresh air treatment operation cost is reduced, so that an efficient purification effect is achieved.

Description

Technical field [0001] The invention belongs to the field of building fresh air, and particularly relates to a filter module used in a fresh air system and a production method of the module. Background technique [0002] Due to serious air pollution in recent years, many types of fresh air purification devices and systems have been spawned, mainly physical filtration, HEPA, HV and electrostatic dust removal, etc., in the removal of gaseous toxic and harmful substances, mainly activated carbon bags and carbon fiber nets and other adsorption materials In addition to PM10 and PM2.5 particulate matter, there are nitrates, sulfates, carbon monoxide TVOC, ozone, hydroxides and peroxides in the atmosphere, which are harmful to human health. In addition, there are electrostatic precipitators to remove dust Medium potential difference and electric field are prone to produce ozone and peroxide which are harmful to human health. [0003] Therefore, it is difficult to deal with the gaseous po...

AI Technical Summary

Problems solved by technology

[0002] Due to the serious air pollution in recent years, many types of purification fresh air devices and systems have been born, mainly physical filtration, HEPA, HV and electrostatic dust removal, etc., for the removal of gaseous toxic and harmful substances, mainly activated carbon bags and carbon fiber nets and other adsorption materials ;Besides PM10 and PM2.5 particles in the atmosphere, there are nitrates, sulfates, carbon monoxide TVOC, ozone, hydroxides and peroxides, etc., which are harmful to human health. Medium potential difference, electric field, easy to produce ozone and peroxide which are harmful to human health

[0003] Therefore, whether it is only physical filtration of particulate matter or hypothetical activated carbon adsorption packs and carbon fiber nets, it is difficult to deal with the gaseous pollutants in the fresh air and the long-term efficient operation of the adsorption materials without secondary pollution, microbial mold growth, etc., and with Fresh air with air negative ions

[0004] Due to the traditional adsorption materials, it is not convenient for airborne desorption, and the adsorption and purification function will soon lose the adsorption function. Therefore, the activated carbon of many purifiers can only be used at the beginning, and the time is short, and it will work for a period of time. ), can not be desorbed, not only has no purification effect, but also easily produces microbial molds, etc., causing secondary pollution and other common technical problems in the industry. At the same time, gaseous purification materials lack standardized installation and convenient replacement
