Postposition type plasma cleaning device

Abstract

The invention discloses a postposition type plasma cleaning device. In the whole device, a primary efficiency filter, a medium efficiency filter, a plasma electric field, a cooling device, a fan, a sound eliminator I and a high efficiency filter are sequentially and fixedly connected into a whole by using connecting flanges to form an air flue; air return openings which are arranged at both sides of a clean room are communicated by a sound eliminator II which is connected with an air return flue fixed between the primary efficiency filter and the medium efficiency filter; and a heat pump is fixed to one end of the cooling device. By adopting a flat grid plasma generator, the postposition type plasma cleaning device disclosed by the invention achieves the effects of high polarization voltage, large dust collecting area, less air resistance, low energy consumption and high dedusting and sterilization efficiency, has the advantages of convenience in disassembly and cleaning, low use cost, wide application range and obvious sound eliminating effect and is quite suitable for places needing sterilization, disinfection, dedusting and air purification.

Description

technical field [0001] The post-mounted plasma cleaning device of the present invention relates to the technical field of clean ventilation, and is applied to the cleaning of pharmacy, food and operating rooms. Background technique [0002] The existing high-voltage electrostatic air purification device uses high-voltage direct current discharge to generate plasma, which charges dust and bacteria and is adsorbed by the plate to kill them. The needle-shaped electric field, although the former is a high-efficiency electric field, has high precision requirements, relatively complicated process, and high manufacturing cost; the latter electric field has high polarization voltage, short dust collection distance, and small dust collection area, resulting in dust removal and sterilization. The area and effect are not ideal. Due to structural reasons, cleaning is relatively difficult, high wind resistance, high energy consumption, and uneconomical. Contents of the invention [00...
