Description

A new type of photocatalytic air sterilizer

technical field

The utility model relates to a novel photocatalytic air sterilizer, which belongs to the technical field of air sterilization equipment.

Background technique

Existing air sterilizers mainly include ozone air sterilizers, ultraviolet air sterilizers, plasma air sterilizers and photocatalyst air sterilizers; among them, the ozone air sterilizer dissociates oxygen into oxygen atoms through high-energy ions, and the oxygen atoms re-mix with oxygen. Molecules combine to form ozone; ozone can oxidize and decompose mold spores, bacteria and other odor-causing bacteria floating in the air, completely eliminating mold, and because ozone is a gas, it is pervasive for killing bacteria and is widely used in the food industry; however, ozone is widely used in the food industry. The smell strongly stimulates the human respiratory tract, causing sore throat, chest tightness and coughing, which can easily lead to bronchitis and emphysema. Therefore, it is necessary to regularly monitor the concentration with an ozone meter. It is irradiated to destroy the structure of DNA (deoxyribonucleic acid) in its body, causing it to die immediately or lose its ability to reproduce; it has low energy consumption and low operating costs; it has a high degree of automation; it is easy to maintain and has no secondary pollution. ; But because ultraviolet rays can penetrate cells and make them die, so when disinfecting with ultraviolet rays, be careful not to directly irradiate human skin, especially human eyes; when there is too much dust in the air, the lamp tube is easy to accumulate dirt film, which needs to be cleaned regularly. Otherwise, the disinfection effect will be affected by inhibiting the transmission of ultraviolet rays; the plasma air sterilizer can generate positive ions and negative ions at the same time, and generate huge energy release at the moment of neutralization of positive and negative charges in the air, resulting in changes in the surrounding bacterial structure or The conversion of energy, resulting in the death of bacteria, to achieve its sterilization effect; its sterilization is rapid and thorough, the sterilization rate of natural bacteria in the air reaches 100% in 30 minutes, and the sterilization rate of Escherichia coli, Staphylococcus aureus, and Candida albicans reaches 99% in 40 minutes. % or more; it is not necessary to replace the filter screen, just clean it regularly; but if the surface of the integrated room of this type of air sterilizer starts to accumulate particles, the filtering effect will be rapidly and greatly reduced, requiring frequent maintenance; when the integrated board is dirty, it will It emits a crackling sound and is easily damaged; and this filtration method will generate ozone, which is irritating to the human respiratory organs; the photocatalyst of the photocatalyst air sterilizer will produce a photocatalytic reaction similar to photosynthesis under the irradiation of light, resulting in oxidation capacity.
