A low-voltage electrostatic dust removal module and air purification device

Abstract

The invention discloses a low voltage electrostatic dust collection module and an air purification device. The low voltage electrostatic dust collection module comprises a positive electrode low voltage electrostatic dust collection unit, a negative electrode low voltage electrostatic dust collection, an electrostatic generator and a degeneration control adjuster, wherein the positive electrode low voltage electrostatic dust collection unit and the negative electrode low voltage electrostatic dust collection at least comprises a layer of electrostatic dust collection filter screen; each electrostatic dust collection filter screen comprises a conductive non-woven fabric filter screen with a microcellular structure; the electrostatic generator continuously conveys a positive charge to the conductive non-woven fabric filter screen in the positive electrode low voltage electrostatic dust collection unit, and continuously conveys a negative charge to the conductive non-woven fabric filter screen in the negative electrode low voltage electrostatic dust collection unit; the degeneration control adjuster is used for monitoring an electric charge quantity change on each conductive non-wovenfabric filter screen, and feeding back changed signals to a control system; and the control system controls a periodic intermitting supply manner of the electrostatic generator and the magnitude of output voltage according the feedback signals. The conductive non-woven fabric filter screens are utilized for loading a static charge so as to form a contact electrification mechanism, so that the generation of ozone can be completely avoided.

Description

technical field [0001] The invention relates to the field of electrostatic dust removal type air purification, in particular to a low-voltage electrostatic dust removal module and an air purification device. Background technique [0002] In recent years, with the improvement of people's living standards, a large number of new decorative materials, furniture and daily necessities have continuously entered the room, and the resulting indoor air pollution has become increasingly serious. At the same time, according to the "2017 Beijing-Tianjin-Hebei Air Pollution Prevention and Control Summit Forum", my country's air pollution is characterized by explosive occurrence, regional spread, long duration, and prominent secondary pollution. Among them, the contribution rate of secondary pollutants to PM2.5 is as high as 80%. Therefore, more and more people begin to pay attention to air quality, and indoor air purification products are gradually favored by the masses. Among them, elec...

Problems solved by technology

However, the amount of charge generated by this frictional electrification method is very limited; the continuous movement of the equipment consumes a lot of energy; it will inevitably produce movement noise; the stability of the continuous movement equipment is low; its charging of uncharged dust in the air Low efficiency and adsorption efficiency

[0007] Therefore, in view of the problems of low dust removal efficiency, high-voltage ionization that inevitably produces ozone and high cost in the existing electrostatic precipitator technology, a low-voltage electrostatic precipitator that completely avoids ozone generation, high efficiency and energy saving, economical and practical, easy to clean and has a long service life is designed and manufactured. The module and the air purification device composed of it have important economic and social benefits
