Air purification device capable of filtering and killing pathogenic microorganisms by use of porous ceramic membrane

Abstract

The invention discloses an air purification device capable of filtering and killing pathogenic microorganisms by use of a porous ceramic membrane. The air purification device comprises an air accommodating and collecting region, wherein the air accommodating and collecting region is provided with a vitiated air inlet and a clean air outlet; the part, which is adjacent to the clean air outlet, in the air accommodating and collecting region is provided with the porous ceramic filtering membrane; the air accommodating and collecting region is internally provided with a disinfection component, and the clean air outlet is provided with a blower. The inorganic ceramic membrane adopted by the air purification device has the characteristics of high temperature resistance, corrosion resistance and ageing resistance, so that the air purification device is long in service life, especially has higher separation precision and separation efficiency than those of a traditional purifier, and can effectively ensure that the pathogenic microorganisms are completely intercepted and are completely killed in equipment by use of high temperature, ultraviolet light or a chemical disinfection solution so as to prevent virus from spreading, polluting and infecting towards the environment by virtue of exhausted air. The air purification device is simple in equipment structure, high in stability, reproducible in core component, convenient to use and thorough in pathogenic microorganism killing effect.

Description

technical field [0001] The invention belongs to the technical field of air filtration, purification and killing of pathogenic microorganisms, and relates to an air purification device which adopts a high-temperature-resistant porous filter medium to retain pathogenic microorganisms, and then kills pathogenic microorganisms by high temperature, ultraviolet light or chemical disinfectant. Background technique [0002] Infectious atypical pneumonia (hereinafter referred to as "SARS" or "SARS") is a respiratory infectious disease, and the current situation shows that air is its main medium of transmission. One of the keys to fighting SARS is to avoid further infecting others. In particular, areas such as "SARS" wards, "suspected" wards or "fever clinics" have extremely high virus concentrations in the air. Healthy people in these areas, especially medical staff, are most likely to be infected. On the other hand, patients themselves may also continue to be infected. Studies hav...

AI Technical Summary

Problems solved by technology

Although the currently commercially available air purification devices have a certain effect of filtering out dust, bacteria and viruses, there is no description of components that can completely filter viruses

In addition, because the filter medium materials used are generally not resistant to high temperatures, there has been no use of high temperature heating to kill the virus on the filter medium materials; there is no report of additional chemical disinfection functions, and air filtration cannot be filtered, killed, or eliminated. Viruses in the purifier, making it difficult to prevent the spread, contamination and infection of viruses

The filter parts of ordinary ventilation devices such as central air conditioners often filter high concentrations of bacteria and viruses. When used in "SARS" wards, it is difficult to receive filtration and purification effects, and the virus may spread to a wider range.
