Abstract
A cryogenic full containment storage tank for realizing a low-liquid-level material extraction function by using a pump column, comprising an inner tank, an outer tank, a pump column, a submersible pump and a material pre-extraction device; wherein the material pre-extraction device comprises a cofferdam, a Venturi mixer, a backflow pipe, a return control valve, a lead-out pipeline and a liquid level detection system. The cryogenic full containment storage tank can make use of a low-temperature medium flowing back from the pump column to extract the low liquid level material outside the cofferdam into the cofferdam to form a local high liquid level and maintain the normal operation of the submersible pump.
