Microwave radiation water-film-type drinking water sterilizing system

Abstract

The invention discloses a microwave radiation water-film-type drinking water sterilizing system. The microwave radiation water-film-type drinking water sterilizing system comprises a to-be-sterilizedwater storage chamber, a sawtooth-type microwave scatter plate, a microwave cavity, a built-in flow regulating valve, a microwave scattering cone, an upper water film forming plate, a magnetron pillar, a magnetron, a lower water film forming plate, a sterilized water storage area, an external valve, and a wall surface. The microwave cavity is divided to a microwave working area I and a microwave working area II by the upper water film forming plate and the lower water film forming plate. The lower part of the to-be-sterilized water storage chamber is a circular vertical water inlet. The lowerpart of the sterilized water storage area is a circular vertical water outlet. The upper water film forming plate is suspended by three sling chains. The lower water film forming plate is supported bythree inclined columns. The system has the advantages of high microwave utilization ratio, good drinking water sterilizing effect, and long service life of the magnetron.

Description

technical field [0001] The invention relates to a drinking water disinfection system, in particular to a microwave radiation water film type drinking water disinfection system. Background technique [0002] When microwaves radiate to the surface of microorganisms, they can easily penetrate the cell walls of microorganisms and enter the microorganisms, using their unique thermal and non-thermal effects to change or destroy the cytoplasm of microorganisms, and even the genetic material in them, causing them to die or lose their genetic ability. Therefore, microwave sterilization technology has been applied in the field of drinking water disinfection. [0003] The practical application of microwave sterilization technology reflects some deficiencies: [0004] On the one hand, conventional microwave generators use magnetrons to generate microwaves, which are transmitted into the microwave cavity through wave guides, and then radiate the materials in the microwave cavity under t...

AI Technical Summary

Problems solved by technology

This working mode has been widely used in society, but when the microwave radiates the material in the microwave cavity, part of the microwave will enter the waveguide again and be transmitted back to the magnetron, which will cause harm to the magnetron;

[0005] On the other hand, during the disinfection process of drinking water by microwave radiation, due to the limitation of penetration depth, only the surface layer of drinking water can be effectively disinfected, while the inside of drinking water cannot receive sufficient microwave radiation, resulting in a decline in the overall disinfection effect of drinking water
