Tester for testing purifying effect of waste gas from air purifier in ship sealed cabin

The utility model relates to a tester for testing purifying effect of waste gas from an air purifier in a ship sealed cabin, which can test the exhaust capacity and purification treatment effect of the air purifier. The utility model mainly comprises an inlet and outlet regulator tube, a valve, an analog housing, a stirrer, an air purifier, hydrocarbon, carbon monoxide, a dioxide cylinder, an effusion meter, a micropressure tilting measuring apparatus, a gas component measuring apparatus and an engine emission measuring apparatus. When the components of hydrocarbon, carbon monoxide and carbon dioxide in the analog housing coincide with the components of the technical requirements and reach a stable state, and the fluid pressure, the fluid velocity and the gas components passing through the air purifier in the outlet regulator tube can be tested. The air output of the air purifier can be obtained on the ground of the velocity of the outlet tube; whether the purification effect of the air purifier coincides with the design requirements or not can be judged on the ground of the comparison of the gas components in the housing and the outlet of the air purifier. The tester has the advantages of simple structure, low fabrication cost, working stabilization, and can effectively judge the air output and the purification efficiency of the air purifier.
