Multi-channel purifier for removing air-borne microbial particles

Abstract

The invention belongs to the field of air purification, and discloses a multi-channel purifier for removing air-borne microbial particles. At least two filter modules are arranged in the purifier; a plurality of purification units are arranged in each filter module; and each purification unit accelerates airflow by virtue of an airflow jet device, and the air-borne microbial particles impact ontoa particle collection plate by virtue of inertia. A plurality of jet acceleration nozzles are formed in the airflow jet device, a plurality of collection grooves are formed in the collection plate, the nozzles correspond to the grooves, and an ultraviolet sterilization lamp is arranged in each purification unit and used for carrying out irradiation inactivation on the collected microbial particles. The filter modules are connected in a cascading manner, and a fan is arranged among the filter modules. The purpose that the impact collection efficiency of the purifier for the microbial particlesis unchanged when the needed running air quantity of the purifier is changed is met through the linkage of the starting number of the cascading purification units. According to the purifier disclosedby the invention, the problems of the inertial impact of the particles and the reduction of collection efficiency in the case that the needed clean air quantity is changed, are solved; and meanwhile,the ultraviolet inactivation for the captured microbial particles is realized, so that a good control effect on a bioaerosol for an indoor environment is guaranteed.

Description

technical field [0001] The invention relates to the field of indoor air purification, and can be used for collecting and purifying microbial particles in indoor air, and inactivating the collected microbial particles. Background technique [0002] At present, HEPA filters are mainly used in air purifiers to collect and purify airborne particles. This method can filter particles with high efficiency, but the HEPA filter is a porous medium. After adsorbing water vapor or particle moisture, it is easy to become a place for microorganisms to multiply. Once these microorganisms are aerosolized and enter the indoor air, it will cause air pollution. Secondary pollution. UVC UV lamps have an efficient inactivation and sterilization effect on microorganisms. However, the porous structure of the HEPA filter will hinder the penetration of ultraviolet light, and it is difficult to ensure the ultraviolet light dose required to kill microorganisms. The particle collection or purificatio...
