油田转油站、转油脱水站原来采用的污油回收装置存在着工艺繁琐，占地面积大，容积泵易卡，功率较大，管理不便等不足。现提供一种用电量小，污油罐与泵组装为一体的新型污油回收装置。该装置结构包括罐体（罐体的壁上装有伴热的集油汇管），上盖（上盖上装有一台多级离心泵） There are some problems in the oil-gas recovery plant originally used in the oil-gas conversion station and the oil-transfer dehydration station, such as complicated processes, large floor space, easy volume card pumping, large power consumption and inconvenient management. Is to provide a small power consumption, sewage tank and pump assembly as one of the new type of oil recovery unit. The structure of the device comprises a tank body (a heat collecting oil collecting pipe is arranged on the wall of the tank body), an upper cover (a multistage centrifugal pump is arranged on the upper cover)
