The pneumatic reducing printing and dyeing waste gas oil suction pipe as claimed in claim 1, characterized in that: the thermal expansion powder (4) is prepared by mixing ammonium chloride powder and heat-conducting aluminum powder, and the mixing ratio of the ammonium chloride powder to the heat-conducting aluminum powder is 1: 1.
7. The pneumatic reducing type printing and dyeing waste gas oil suction pipe as claimed in claim 2, characterized in that: the metal pulling rope (10) is made of a nickel-titanium memory alloy material, and the equilibrium temperature of the metal pulling rope (10) is 40 ℃.
8. The pneumatic reducing type printing and dyeing waste gas oil suction pipe as claimed in claim 2, characterized in that: the side short filaments (11) are made of animal hair, and the built-in U-shaped bag (3) is made of a rubber material.
9. The use method of the pneumatic reducing printing and dyeing waste gas oil suction pipe according to any one of claims 1 to 8, characterized in that: the method comprises the following steps:
s1, transmitting high-temperature printing and dyeing waste gas through the waste gas transmission pipeline (1), and absorbing heat in the high-temperature waste gas to promote thermal expansion powder (4) in the built-in U-shaped bag (3) to be heated and rapidly decomposed, so that air pressure in the built-in U-shaped bag (3) is improved, and the built-in U-shaped bag (3) is stretched to be U-shaped;
s2, the pre-oil absorption cotton (5) is fully extended, so that the absorption efficiency of oil stains in the printing and dyeing waste gas is improved, and the radius of the inner wall of the waste gas transmission pipeline (1) where the printing and dyeing waste gas is located can be changed by means of the change of the built-in U-shaped bag (3), so that the dynamic change of the printing and dyeing waste gas is increased;
s3, after the temperature is reduced, the built-in U-shaped bag (3) can be promoted to be changed into an M shape by means of the adsorption of the magnetic movable ball (9) on the waste gas transmission pipeline (1), so that the pre-oil absorption cotton (5) is extruded, and the efficiency of transmitting the oil stain in the pre-oil absorption cotton (5) to the outer oil absorption oil pocket layer (2) is improved.
