A plasma air sterilizer

Abstract

The invention discloses air purification and disinfection equipment capable of generating uniform high-concentration plasma. The equipment mainly comprises a housing (1), a fan (2), a plasma generator (3) and a boosting power supply (4), wherein the plasma generator (3) consists of a plurality of cylindrical plasma fundamental reaction units (30); the cylindrical plasma fundamental reaction units (30) comprise positive electrodes and negative electrodes; the positive electrodes are discharge electrode wires (310); the negative electrodes are hollow metallic circular tubes (320); the metallic circular tubes take the discharge electrode wires as center shafts; end covers (330) made of non-conducting insulation materials are arranged at the two ends of each metallic circular tube (320); and a plurality of hollow through holes (B) are formed in the two end covers (330). According to the equipment, air entering an air disinfection machine can be excited to be the uniform high-concentration plasma, so that indoor air can be disinfected, sterilized, dedusted and deodorized rapidly and effectively.

Description

technical field [0001] The invention relates to an air purification device, in particular to a plasma air disinfection and purification equipment, belonging to the technical field of air disinfection and purification. Background technique [0002] With the development of society and the progress of science and technology, people's quality of life is constantly improving. At the same time, people's requirements for living environment are also increasing day by day, which promotes the development of various air purification and disinfection products. In recent years, China's plasma disinfection industry has developed rapidly. In the field of air disinfection, a large number of plasma air disinfection equipment have appeared. For example, in the Chinese Utility Model Patent No. 200320109397.5, a plasma air sterilization purifier is disclosed, including a housing, a fan, an air filter, a plasma reactor, a photocatalytic sterilization filter, and an anion generating area. The ai...

Problems solved by technology

In addition, the photocatalytic sterilizing filter of the plasma air sterilizing purifier disclosed in this patent uses photochemical media, and the cost is relatively high

The entire device is not equipped with a protection circuit, and the power supply cannot be automatically disconnected in time under conditions such as overhumidity, overheating, high temperature and short circuit, which not only wastes energy, but also makes the service life of the device short

In order to overcome the above technical deficiencies, the applicant submitted a plasma air purification and disinfection device with application number 201210221506.6 on June 30, 2012. This technology mainly consists of a wave-shaped electrode plate and a discharge metal wire parallel to it. Basic reaction unit, this technology can generate high-concentration plasma, but in actual operation, it is found that there is a phenomenon of charge concentration at the peak of the wave-shaped electrode plate, so that the plasma in the reaction unit is slightly insufficient in uniformity
