The impurities in the oil gas are primarily filtered by the filter device 22 and then are introduced into the inner cavity of the device shell 1. The reaction filtrate is arranged in the inner cavity of the device shell 1. The oil gas is fully contacted with the reaction filtrate, so that tail gas and some impurities are obtained. The exhaust gas is discharged through the exhaust port 11. And the impurities and the internal reaction filtrate are pumped out by the oil pumping device. During the contact reaction process of the oil gas and the reaction filtrate, the temperature sensor 6 feeds back a signal to the control device 5 by measuring the temperature of the inner cavity, and the control device 5 controls the refrigerating plate 4 in the inner cavity to work according to the temperature information, so that the reaction filtrate in the inner cavity is always at the optimal reaction temperature.
