The utility model discloses a purifying and retrieving device, which is used to dispose the waste gas exhausted during the production of pvc products. The device is composed of heat exchanger, heat exchanger cooler system for water pump and cooling tower and turbulent ball tower style drop catcher comprising turbulent ball tower and oil-wet net. The heat exchanger is equipped with waste gas inlet, waste gas outlet and oil outlet. There are waste gas inlet and waste gas outlet on the turbulent ball tower style drop catcher. The waste gas outlet of the heat exchanger and the waste gas inlet of the turbulent ball tower style drop catcher are linked up. The waste gas outlet of the turbulent ball tower style drop catcher is connected to the chimney. The utility model manages to effectively remove the organic compound from the waste gas so that the organic compound can be directly retrieved in the form of oil. The purifying efficiency reaches up to ninety percent. Compared with the sprinkler system, it is more convenient to retrieve the mixture of oil and water. Economization on raw materials leads to great economic returns. Compared with the method that only heat exchanger cooler system is applied to purify and retrieve the waste gas, the device can catch more oil and improve the efficiency. Compared with electric precipitation, the device features small investment, high efficiency and high safety.
