Automobile tail gas purifying apparatus with forced water circulation

The utility model discloses an automobile tail gas purifying device with forced water circulation, which is suitable for purifying the automobile tail gas. The utility model is composed of a rounded barrel, an inner oil gas fixing and gas-water separating barrel and a second stage purifying barrel. The rounded barrel is made of metal casing and is used as a radiation fin and a water tank. A screw blade water pump, an oil-gas separator, a gas-water separator and a purifier are connected into a rotating whole body by a rotating shaft and a shaft connector. The dynamic force of the rotating whole body is provided by a motor. The water in a water tank can be sucked by the screw blade water pump and can be ejected to form water fog and to be mixed with automobile tail gas. Harmful substances which can dissolve in water and small particulate materials which can adhere in water and are indissolvable in water can be absorbed. Separated by gas and water, the tail gas can be further purified by activated carbon finally and can be exhausted into atmosphere.
