Description

Ozone sterilization disinfection cleaning system
Technical Field
The invention relates to an ozone sterilization disinfection cleaning system, and belongs to the technical field of disinfection cleaning.
Background
Along with the development of society, the demands of people on the sterilization, disinfection and cleaning of articles are higher and higher, and ozone is more tolerant because the sterilization, disinfection and the cleaning of articles are broad-spectrum, have no dead angle and have no residues.
Ozone is an allotrope of oxygen, has strong oxidability, has extremely unstable molecules, can be decomposed to generate monoatomic oxygen (O) and hydroxyl (OH) with extremely strong oxidizing ability, is a unique bacterial-thawing preparation, can be quickly fused into cell walls, damages the internal structures of microorganisms such as bacteria and viruses, and has extremely strong killing effect on various pathogenic microorganisms. The sterilization process belongs to biochemical oxidation reaction. The function is realized mainly by the following three forms: (1) Ozone can oxidize and decompose enzymes required by glucose in bacteria, so that the bacteria are inactivated and killed; (2) Nuclear substances acting on bacterial cells, such as purines and pyrimidines in nucleic acids, destroy their organelles and DNA, RNA, and destroy the metabolism of the bacteria, resulting in bacterial death; (3) Ozone reacts with lipid double chains on the cell wall of bacteria, penetrates through cell membrane tissues, invades cells, acts on lipoproteins of an outer membrane and lipopolysaccharide in the inner membrane, and causes the bacteria to be dissolved and dead due to permeability aberration; (4) Ozone acts on the 4 polypeptide chains of the viral capsid protein and damages the RNA, destroying the proteins that form it. After the phage is oxidized by ozone, its epidermis is broken into many fragments, from which many ribonucleic acids are released, interfering with its adsorption to the register.
Ozone is harmful to human body due to fishy smell and the residual concentration exceeds the standard, but the ozone concentration cannot be thoroughly sterilized if the ozone concentration does not reach the standard, and the existing ozone sterilization products mainly have the following three problems:
firstly, the ozone concentration is low, so that the effect is difficult to achieve;

thirdly, ozone is easy to remain after sterilization and disinfection.
