Air disinfection and purification device based on plasma in-situ coupling nano-catalysis

Abstract

The invention discloses an air disinfection and purification device based on plasma in-situ coupling nano-catalysis, which comprises a shell, a power supply, a connecting piece and at least one catalytic discharge unit. The connecting piece and the catalytic discharge unit are arranged in the shell; the connecting piece is connected with the shell; the catalytic discharge unit is connected with the connecting piece; the catalytic discharge unit comprises a first electrode assembly and a second electrode assembly which are connected with a power supply; a plasma field is generated between the first electrode assembly and the second electrode assembly; a nano-catalyst is arranged between the first electrode assembly and the second electrode assembly; the nano-catalyst is arranged in the plasma field; an air inlet and an air outlet are formed in the shell; and airflow in the shell passes through the plasma field and is in contact with the nano catalyst. The air disinfection and purification device provided by the invention integrates the functions of dust removal, organic pollutant removal, sterilization and disinfection and the like, and has the advantages of being high in energy utilization rate, obvious in sterilization effect, compact and simple in structure, small in overall size and the like.

Description

technical field [0001] The invention belongs to the field of discharge plasma and catalysis, in particular to an air disinfection and purification device based on plasma in-situ coupled nano-catalysis. Background technique [0002] Indoor air quality is closely related to people's health status, and there are many types of pollutants that cause indoor air quality degradation, including particulate matter, organic pollutants, and pathogenic microorganisms. [0003] In recent years, air purifiers based on plasma technology have been widely used. The principle is to use high-energy electrons generated by plasma to interact with O and HO 2 , OH and other free radical active species have a strong ability to inactivate bacteria and viruses. This type of air purifier has the advantages of low operating temperature, rich in highly active species, strong particle capture ability, and simple and easy equipment. However, this type of air purifier still has many outstanding problems in...
