Residual oil collecting and recycling system for oil storage container

The invention belongs to the technical field of oil storage container residual oil collection and recovery, and particularly relates to an oil storage container residual oil collection and recovery system which comprises an oil storage container, a gas-liquid centrifugal separator, a gas-liquid sedimentation separator, an oil recovery tank, a vacuum compressor and an oil-gas separator. An oil suction head is arranged at the bottom of the inner side of the oil storage container, and an oil discharge gas pipe is connected between the oil suction head and the oil discharge gas valve. According to the residual oil collection and recovery system for the oil storage container, the residual oil is recovered by utilizing the air flow above the outer oil suction cylinder to carry the bottom oil, the oil suction head cannot be adsorbed on the bottom wall of the oil storage container, and the working stability is relatively good; bottom oil and oil gas in the container can be extracted and removed, and the oil product r
