Efficient and rapid toilet air disinfection device and use method thereof

Abstract

The invention relates to an efficient and rapid toilet air disinfection device which can work in a working mode I and a working mode II, comprises a movable disinfection machine body, and is characterized in that a PLC control module, a pretreatment area, a fan area and a photocatalytic oxidation area are arranged in the disinfection machine body. Another technical scheme of the invention is to provide a use method of the efficient and rapid toilet air disinfection device. The efficient and rapid toilet air disinfection device and the use method thereof have the advantages that titanium dioxide loaded silver nanoparticles not only effectively separate photo-induced electrons and holes and improve the photocatalytic efficiency, but also can assist in sterilization and disinfection of activeoxygen and hydrogen peroxide; silver nanoparticles and titanium dioxide nanoparticles are coupled, a specific Z-path photo-induced electron conduction path is adopted, the energy band width is reduced, visible light catalysis is adopted, and ultraviolet light pollution is not generated; high removal efficiency is achieved on bacteria, viruses and stink and peculiar smell pollution, and the risk of infectious diseases in toilets due to air transmission can be effectively reduced.

Description

technical field [0001] The invention relates to the field of disinfection and gas purification, in particular to an air disinfection and purification device in a toilet and a use method thereof. Background technique [0002] During the use of the toilet, various odors (organic pollutants), bacteria and aerosols carrying germs are produced. Due to the complex distribution of crowds, frequent use, and large flow of people, public toilets have become one of the places that are potentially infected with germs. [0003] The traditional toilet disinfection method is to spray disinfectant water, and microorganisms such as germs are oxidized and decomposed by the active components of the disinfectant water to achieve the purpose of disinfection. This process has the following disadvantages and deficiencies: disinfection water needs to be sprayed manually, and the ground and handrails are scrubbed, and health personnel are exposed to air containing germs, which increases the risk of...

Problems solved by technology

This process has the following disadvantages and deficiencies: Disinfectant water needs to be manually sprayed, the ground and handrails must be scrubbed, and health personnel are exposed to the air containing germs, which increases the risk of infection

In addition, the oxidation rate and effect of ozone need to be verified urgently.

Utility model patent CN 209877228 U uses photocatalytic system for sterilization and deodorization. The use of ultraviolet light requires high airtightness of equipment, and there is a certain risk of spillage, and the efficiency of catalytic oxidation is low
