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.
