The utility model discloses a waste gas absorbing and purifying device relating to the field of waste gas treatment. The waste gas absorbing and purifying device comprises an absorption liquid tank, a water pump and a draught fan, wherein four absorption liquid inlets and one gas-liquid inlet are formed in a bottom plate of the absorption liquid tank, and absorption liquid in the absorption liquid tank is circularly absorbed and discharged by the water pump to ensure that the absorption liquid forms surging rotational flow in the absorption liquid tank. Waste gas introduced by the draught fan enters the absorption liquid tank from the gas-liquid inlet in the bottom plate of the absorption liquid tank through a gas pipe and is cut into small bubbles at the gas liquid inlet by the absorption liquid subjected to surging rotational flow, so that the gas-liquid contact area is enlarged, the effects of absorbing and purifying pollutants in waste gas by the absorption liquid is enhanced, and the absorbed and purifie
