[0023] It is worth mentioning that when the separation is carried out, the hydrocarbon carried by the process gas is separated out and mixed with water after compression, the liquid water and the hydrocarbon are impacted by the baffle 13 and captured by the mist supplementing screen one 16, then are settled at the bottom of the cavity one 14, and because the density of the hydrocarbon is small, the hydrocarbon is located in the upper layer, and the density of the water is large, the water is located in the bottom layer, further, the water at the bottom is recycled through the water injection pipeline 9, and as the hydrocarbon in the process gas is continuously separated out, the liquid level in the three-phase separator 3 continuously rises, when the liquid level of the cavity one 14 exceeds the intermediate partition plate 21, the upper layer hydrocarbon enters the cavity two 15, when the liquid level of the cavity two 15 reaches a certain value, the liquid level transmitter two 19 controls the pneumatic ball valve two 26 to open, the hydrocarbon is discharged to the collecting device, and the cycle is repeated, so that the water, gas and hydrocarbon three-phase separation is realized.
