New method and device for air purification

Abstract

The invention discloses a new method and a device for air purification. The device comprises an enclosure (1), a charge electrode grid (3), multi-stage adsorption accelerating grids (4-1, 4-2, 4-3 and the like), a negative ion emitter (5), an ozone decomposition unit (6), a high-frequency high-voltage power supply (2) and the like, wherein the charge electrode grid (3), the multi-stage adsorption accelerating grids (4-1, 4-2, 4-3 and the like), the negative ion emitter (5) and the ozone decomposition unit (6) are arranged in the enclosure (1). When high air quantity is needed, a fan can be arranged in front of the charge electrode grid (3) or in front of an air outlet. The device is characterized in that: in the enclosure, the (3), the (4-1, 4-2, 4-3 and the like), the (5) and the (6) are sequentially arranged in the direction from an air inlet to the air outlet. The (2) is arranged in a closed space. An electric field is arranged downwind or upwind in the direction from the charge electrode grid (3) to the negative ion emitter (5). The field intensity is of gradient. The high-frequency high-voltage power supply (2) has multi-stage voltage output. When the electric field is arranged downwind, the high-voltage '+' pole is connected with the (3), and the high-voltage '-' pole is connected with the first, second and third adsorption accelerating poles (4-1), (4-2) and (4-3) and the negative ion emitter (5) respectively. When the electric field is arranged upwind, the poles of the (2) are connected reversely, and the (5) is removed at the same time. The device has simple and reasonable integral structure, is sufficient to decompose and adsorb pollutants, generates more negative oxygen ions, and is convenient to clean.

Description

technical field [0001] The invention relates to a new method and device for air purification, which is suitable for air purification and belongs to the technical field of environmental protection. Background technique [0002] Air purification technology, air filtration, water washing, adsorption, photocatalysis, ultraviolet radiation, ozone and negative oxygen ions, etc. or a combination of several technologies are widely used. In recent years, electrostatic adsorption air purification technology has been widely developed and applied. Most of them use plate electrodes, tip discharge or halo wire discharge to charge dust, and then use plate electrodes with opposite charges to absorb dust to achieve the purpose of air purification. Electrostatic adsorption, smoke and dust removal effect is good, some viruses, pathogenic bacteria, etc. are adsorbed with the smoke and dust, but the killing is not thorough enough. The removal effect of organic pollutants is poor. There is only...
