The principle of sterilization and disinfection is as follows: see Figure 1,

Steps of the first function: the first function is to perform indoor air disinfection. The indoor bacteria-carrying air enters the machine, the coarse and medium-efficiency filters 2 and 3 filter the air, and the electrostatic precipitator 5 electrostatically absorbs dust and bacteria; the air is supplied by the circulating fan 2; the high-intensity ultraviolet radiation sterilization is completed by the high-intensity ultraviolet tube 7; The inside of the casing is provided with a high-efficiency nano photocatalyst filter screen 9 to complete.

Steps of the second function: if fresh air is needed indoors, use the control panel to automatically turn on the fresh air duct switch 14 and turn off the exhaust gas duct switch 22 at the same time. The fresh air enters from the tuyere 11, passes through the disinfection and deodorizer 12, the fresh air blower 13, the fresh air duct switch 14, the fresh air coarse filter and the medium effect filter 15 from top to bottom, and then enters the chamber 16; Step processing.

The step of the third function: if exhaust gas needs to be removed indoors, use the control panel to automatically turn off the fresh air duct switch 14 and turn on the exhaust gas duct switch 22 at the same time. The waste gas passes through the waste gas inlet 21 and the waste gas duct switch 22. Since the outlet 23 of the waste gas pipe 20 is connected to the top of the fresh air pipe 10, the waste gas is discharged outside from the tuyere 11.

Product performance and main features:

1. The laminar flow dynamic air disinfection machine is an upgraded product developed, developed and produced by itself according to the requirements of the "Technical Specifications for Disinfection" newly issued by the Ministry of Health and the requirements of GB9706·1-2007 "Medical Electrical Equipment Part One: General Safety Requirements" . This machine can replace chemical fumigation to disinfect indoor air, and can meet the indoor air disinfection requirements for indoor air in Class II and III environments stipulated in the "Disinfection Technical Specifications" 2002 board newly issued by the Ministry of Health.

2. At the air inlet of the casing are coarse and medium-efficiency filters 2 and 3, which adopt a unique multi-stage filter electrostatic adsorption net. Exhaust gas, remove pollutants in the air, and create conditions for post-stage purification; high-tech nano-photocatalyst semiconductor technology is applied, and a high-efficiency filter is installed inside the casing. , produce strong oxidizing hydroxyl radicals, which can effectively decompose harmful gases in the air, kill bacteria, inhibit virus activity, and decompose them into harmless substances. Under the irradiation of ultraviolet lamps in the machine, strong The photocatalytic reaction can effectively kill bacteria and viruses passing through the machine, decompose harmful gases in the air, such as formaldehyde, benzene, ammonia, etc., and can release negative oxygen ions, which can greatly improve the efficiency of the air sterilizer.

3. The fresh air strongly compensates for the fresh air, which is completed by the fresh air pipeline 10, the disinfection deodorizer 12, the fresh air blower 13, the fresh air duct switch 14, and the coarse and medium-efficiency filters 15.

4. Disinfect and deodorize the return air exhaust gas. Completed by exhaust duct 20 .

5. Ultraviolet radiation sterilization. Use the ultraviolet C-band 253.7nm D-type ultraviolet tube 7 to further kill the bacteria in the air; when the ballast is working, high-frequency voltage is generated, and the high-intensity ultraviolet tube produces ultraviolet light to sterilize. It also has functions such as automatic display of ultraviolet intensity, automatic alarm for ultraviolet tube failure, and automatic startup of spare ultraviolet tubes.

Scope of application: This product is suitable for air disinfection in operating rooms, intensive care units, burn wards, pathology rooms, supply rooms, preparation rooms, neonatal intensive care units, and hemodialysis rooms. It is also used for air disinfection in packaging workshops, inspection rooms, blood product laboratories, and biochemical analysis rooms of pharmaceutical factories, and in packaging workshops and laboratories of food factories.
