Ceramic photo-catalyst filter element assembly of air disinfecting and sterilizing sterilizer

Abstract

A ceramic photo-catalyst filter element assembly of an air disinfection sterilization sterilizer comprises a ceramic filter element body, a plurality of vent holes penetrating through the upper end face and the lower end face of the ceramic filter element body are formed in the ceramic filter element body, a titanium dioxide coating is sprayed or soaked on the surface of the ceramic filter element body, the thickness of the ceramic filter element body is 20 cm to 50 cm, and ultraviolet lamp tubes are installed on the upper end face and the lower end face of the ceramic filter element body and irradiate the vent holes. The ceramic filter element has the beneficial effects that the ceramic filter element body is formed by die-casting the ceramic material, and the titanium dioxide coating can be uniformly and firmly adhered to the ceramic filter element body by utilizing the characteristic that the surface of the ceramic filter element body is provided with micro-pores, so that the service life is prolonged. The ceramic filter element body is arranged to be large in thickness, and the thickness of the ceramic filter element body is generally larger than 20 cm, so that the contact area and the contact time of air and the filter element can be effectively increased, the reaction intensity and time between titanium dioxide and air and ultraviolet rays are guaranteed, and the sterilization and purification effect on air is improved.

Description

technical field [0001] The invention relates to an accessory of an air sterilizer, in particular to a ceramic photocatalyst filter element assembly of an air sterilizer. Background technique [0002] With the continuous improvement of life, people pay more and more attention to their own health. Since people work and live indoors, the requirements for indoor air quality are getting higher and higher. Because the indoor environment is relatively closed, the indoor air quality is relatively poor, and it is easy to breed germs, thereby endangering people's health. In order to improve indoor air quality, in recent years, people have developed some devices for purifying air quality, such as air purifiers of mechanical filter type, negative ion type, electronic dust collection type and other varieties. However, these models can only purify dust particles and some harmful substances in the indoor air, and it is difficult to completely eliminate the toxic and harmful volatile organ...

Problems solved by technology

Since photocatalysts are usually powdery solids or liquid sols, it is necessary to provide a carrier that facilitates photocatalyst attachment; at present, commonly used photocatalyst carriers include activated carbon felt, activated carbon sponge, paper honeycomb, aluminum honeycomb, wire mesh, etc., but these carriers The adhesion of the photocatalyst film is not strong enough, it is easy to fall off, and the service life is short, so it is necessary to further improve it
