An efficient and energy-saving vertical low-temperature storage tank comprises a tank body (1) provided with a vacuum thermal insulation interlayer, a transmission device positioned on the tank body (1) and comprising a gas return pipe (14) and a liquid outlet pipe (10), and a positioning device arranged on a supporting leg (5) on the bottom end of the tank body (1), as well as an inbuilt saturation regulating mechanism composed of a heat exchanger (8) and a gas return dispersing device (9), which are communicated at the tank inlet port of the gas return pipe. The saturation regulating mechanism is arranged on the tank inlet port of the gas return pipe, thereby fully utilizing a gasified gas generated at a pump body, achieving an LNG saturation regulation function in the storage tank, reducing the energy loss, simplifying the interface arrangement of the storage tank, improving the saturation regulation efficiency and avoiding pump cavitation. |
