8. The spiral channel suction type optical media catalytic waste gas purifying apparatus as claimed in claim 7, wherein: the upper end of the middle catheter (1212) is fixedly connected with a connecting ring (1213), an L-shaped clamping groove (1214) is annularly arranged on the inner side wall of the connecting ring (1213), one end of the connecting pipe (213) is inserted into the connecting ring (1213), and one end of the clamping column (214) is slidably clamped inside the clamping groove (1214).

9. The spiral channel suction type optical media catalytic waste gas purifying apparatus as claimed in claim 8, wherein: protector (22) include with air guide dish (211) inside the dish (221) of accepting of laminating mutually, the upper end of accepting dish (221) is provided with filter screen mount (222), be provided with filter screen (223) between filter screen mount (222) and the lateral wall of accepting dish (221).

10. A purification method of a spiral channel suction type optical media catalytic waste gas purifier, comprising the spiral channel suction type optical media catalytic waste gas purifier as claimed in any one of claims 1 to 9, characterized in that: the method comprises the following steps:

s1, the air suction device (2) is taken down from the absorption device (1), a proper amount of clean water is introduced into the clean water cavity (112) through the middle guide pipe (1212), after the clean water is put in, the air suction device (2) is placed at the top of the absorption device (1), the end clamping ring (114) is inserted into the air guide disc (211), the connecting pipe (213) is inserted into the connecting ring (1213), the clamping column (214) is inserted into the clamping groove (1214), the air guide disc (211) is rotated to enable the air guide disc (211) to drive the clamping column (214) to rotate, the rotating clamping column (214) rotates into one end inside the clamping groove (1214), and the fixed suction device (21) is connected with the air guide device (12).

S2, the rotating fan blades in the air suction fan (212) stir the air outside the device to enable the air to be driven to move towards the air suction fan (212), the air passing through the air suction fan (212) enters the air guide device (12) through the guide of the connecting pipe (213), and the filter screen (223) blocks impurities in the air, so that the impurities are prevented from being absorbed by the air suction fan (212) and guided into the air guide device (12), and the normal use of the air suction fan (212) and the air guide device (12) is prevented from being influenced.

S3, the gas from the connecting pipe (213) enters the middle guide pipe (1212), moves to the bottom of the guide pipe (122) along the guide pipe (122), and enters the clear water chamber (112) through the air holes (1221), the clear water in the clear water chamber (112) filters the particles in the gas to reduce the particle content in the air, the filtered gas enters the photocatalyst solution placing chamber (113) through the air duct (115), the photocatalyst solution at the bottom of the photocatalyst solution placing chamber (113) is absorbed by the opened water pump (141) and is guided through the liquid outlet pipe (143) to make the photocatalyst solution and the air better contact, the photocatalyst solution placed at the bottom of the photocatalyst solution placing chamber (113) contacts and reacts with the air to treat the toxic substances in the air, the toxic substances in the air are reduced, when the air in the photocatalyst solution placing chamber (113) is too much, the baffle (1322) is pushed to rotate by air pressure, so that the gas in the photocatalyst solution placing cavity (113) enters the spiral absorption tube (134) through the air inlet tube (132) and is absorbed by the photocatalyst attached to the inside of the spiral absorption tube (134) again to absorb toxic substances, the air adsorption effect is improved, and the gas flowing out of the spiral absorption tube (134) is guided by the air outlet tube (133) to leave the device.
