Condensation treatment and collection device for tail gas discharged by hydrogen engine

The utility model relates to the technical field of engine bench testing, and discloses a hydrogen engine exhaust gas condensation treatment and collection device which comprises a shell, a gas inlet and a gas outlet are formed in the two sides of the shell respectively, and a spring coil pipe is installed between the gas inlet and the gas outlet; by adding the condensing device for the waste gas, when the sampling equipment runs, the sampling gas entering the equipment is subjected to condensed water vapor treatment, so that components of the equipment are protected from being corroded by water vapor, the service life of the equipment is prolonged, and the loss is reduced; after the torsion elastic plate is pressed, the clamping sleeve is inserted into the exhaust pipe, then the torsion elastic plate is loosened, the torsion elastic plate clamps the surface of the exhaust pipe through resilience force generated after torsion, and the clamping sleeve is fixed in the exhaust pipe, so that the problem that equi
