[0038] 1, device starts and waste gas input

[0039] The power switch of the waste gas sterilization device is turned on, and the whole system is started.

[0040] The waste gas is introduced into the inner cavity of the main machine mechanism 1 through the air inlet pipe 12.

[0041] 2, waste gas filtration and transportation

[0042] The exhaust gas first enters the first hose 21 and is then delivered to the air filter 22.

[0043] The air filter 22 filters the exhaust gas to remove particulate matter and impurities therein.

[0044] The filtered exhaust gas is delivered to the light-transmitting coil pipe in the disinfection sterilization tank 3 through the second hose 23.

[0045] 3. Exhaust gas sterilization treatment

[0046] The exhaust gas flows in the light-transmitting coil pipe while being subjected to ultraviolet radiation of the UV lamp tube in the disinfection sterilization tank 3.

[0047] The ultraviolet radiation kills microorganisms in the exhaust gas, achieving sterilization treatment of the exhaust gas.

[0048] 4. Output of sterilized exhaust gas

[0049] The sterilized exhaust gas after the sterilization treatment enters the third hose 24 through the gas outlet of the light-transmitting coil pipe.

[0052] When maintenance or repair of the disinfection sterilization tank 3 is needed, the power supply of the device is first turned off.

[0053] The cover plate 15 on the machine shell 11 is opened to expose the maintenance opening 14.

[0054] The motor 51 is started, and the output shaft of the motor 51 drives the screw 52 to rotate, thereby driving the movable plate 53 to move along the screw 52.

[0055] The movement of the movable plate 53 drives the disinfection sterilization tank 3 to slide along the combination structure of the slide bar 42 and the slide groove 43 through the push plate 54 and the protrusion 55.

[0056] The rollers 45 at the bottom of the slide bar 42 roll in the slide groove 43, reducing friction and improving mobility.

[0057] Until the disinfection sterilization tank 3 completely separates from the inner cavity of the machine shell 11, subsequent maintenance or repair operations can be conveniently performed.

[0058] 6. Device shutdown and cleaning

[0059] After the maintenance or repair is completed, the disinfection sterilization tank 3 is placed back into the machine shell 11, and the cover plate 15 is closed.

[0060] The motor 51 is turned off, and the power supply of the device is disconnected, completing the entire work process.

[0061] Through the above workflow, the waste gas sterilization device can realize effective filtering and sterilization treatment of waste gas, and is convenient for maintenance and repair of the disinfection and sterilization tank, and ensures long-term stable operation of the device.
