Plasma sterilization device for hospital exhaust system

Abstract

The invention discloses a plasma sterilization device for a hospital exhaust system. The plasma sterilization device mainly comprises a box body, a control system, an inlet exhaust fan and an outlet exhaust fan, wherein a partition plate is arranged in the box body, a plasma generator is arranged on the left side of the partition plate, an ultraviolet UV light source chamber is arranged on the other side of the partition plate, vent holes are formed in two sides of the box body correspondingly, the vent holes are connected with the inlet exhaust fan and the outlet exhaust fan through an air inlet pipe and an air outlet pipe correspondingly, a gas flow regulator is arranged on the air inlet pipe, an alarm is arranged on the air outlet pipe, and the control system is arranged on the outer wall of the box body. According to the device, the exhaust fans are used for feeding ambient air containing microorganisms such as bacteria and germs into the low-temperature ultrahigh-pressure plasma generator through a filter screen, so that the microorganisms lose activity under the action of active groups of plasma, high-speed particle breakdown, ultraviolet rays and the like, meanwhile, conventional ultraviolet disinfection is assisted, the sterilization quality is further ensured, and the device has the characteristics of simple structure, convenience in operation, high safety and good disinfection sterilization effect.

Description

technical field [0001] The invention belongs to the technical field of air purification and plasma sterilization, and specifically provides a plasma sterilization device for a hospital exhaust system. Background technique [0002] Disinfection refers to the treatment of killing or removing pathogenic microorganisms on the transmission medium to make them harmless. A sterilizer is an instrument that can kill or remove all microorganisms on the transmission medium, including viruses, bacterial spores and non-pathogenic microorganisms. According to different working principles, exhaust disinfection and sterilization devices usually have the principle of BH thermal killing technology Exhaust disinfection device based on the principle of ultraviolet killing technology, exhaust disinfection device based on the principle of BU ultraviolet killing technology, exhaust disinfection device based on the principle of BO ozone, plasma, and high-voltage electrostatic killing technology, an...

Problems solved by technology

However, in actual use, the above two utility models cannot conveniently and effectively sterilize the air during use, and cannot monitor the exhaust volume and sterilization quality at any time. There is no alarm measure for sterilization failure, and the safety of exhaust cannot be guaranteed. , and the structure is complex, difficult to clean and maintain
