Air return type photoelectric combined air purification device

The air return type photoelectric combined air purification device adopts the central air-conditioning system to send air to the pre-filter, after filtering out larger particles of dust and hair, it is sent into the plasma (density distribution 1.05x1017 -4.02x1017m-3), through plasma ionization When passing through the ionization zone, bacteria, molds, etc. are ionized and killed by the ionization breakdown; again through the parallel polar plates alternately positive and negative in the dust collecting zone, the fine dust and smoke in the air are adsorbed on the dust collecting electrode under the action of Coulomb force. On the board, through the photocatalytic filter again, it can obtain energy under the action of ultraviolet lamp, decompose formaldehyde, benzene, TOVC and other harmful gases in the air, and at the same time destroy and change the structure of bacteria (deoxyribonucleic acid) under the irradiation of ultraviolet lamp, Make the bacteria die immediately or incapacitate and die, and output fresh air.
