High-energy ultrasonic coupling photocatalytic air purification system

Abstract

A high-energy ultrasonic coupling photocatalytic air purification system comprises an air filter, a packing spray tower, a photocatalyst air sterilization box, a fan, an air pipe, an ultrasonic generator, an ultrasonic energy converter, photocatalytic nanometer liquor, a first ultraviolet lamp tube, a filter membrane, a circulating water pump, a circulating water pipe, a liquid distributor and a water tank. The photocatalyst air sterilization box consists of a second ultraviolet lamp tube and a nanometer photocatalysis plate. Pollutant with large particle sizes in air is removed by the air filter at first, then tiny suspended matters and gaseous pollutant in the air are removed by sterilized purified water, and finally, a residual small part of gaseous pollutant and germ organisms in the air are further removed by the aid of a photocatalytic disinfection and ultraviolet sterilization method. The air purification system has the advantages of fine sterilization effect, high air treatment capacity and the like, can be widely applied to indoor air purification for cabins, public transportation, offices, shopping malls and the like, and has excellent social and economical benefits.

Description

technical field [0001] The invention relates to an air purification device, in particular to a high-energy ultrasonic coupling photocatalytic air purification system, which belongs to the technical field of air purification. Background technique [0002] With the improvement of living standards and changes in lifestyles, people spend more and more time indoors, and the quality of indoor air directly affects people's work and life. Poor air quality can distract people and reduce work efficiency. In severe cases, it can also cause symptoms such as headaches, nausea, fatigue, and red and swollen skin. Therefore, people pay more and more attention to air quality issues. Most of the existing air-conditioning boxes use dry filters, which cannot disinfect and deodorize the air. Dust particles and harmful bacteria in the air will adhere to the filters. If they are not cleaned in time, it will easily cause secondary air pollution; On the other hand, the adhesion of dust particles t...

Problems solved by technology

However, this kind of air purification device cannot effectively remove gaseous pollutants and pathogenic organisms in the air, and there is a potential problem of spreading pathogenic organisms in water to the air

Chinese utility model CN201120115555.2, named pipeline air purification sterilizer, adopts ultraviolet light and photocatalyst method to sterilize the air, but this device can only guarantee air quality when the contact time between air and ultraviolet light and photocatalyst medium is long enough. Sterilization effect, therefore, has certain limitations in practical application
