Problems solved by technology

Among the existing technologies, the upper and inner support structures of low-temperature storage tanks currently used at home and abroad include: 1) The heat-insulating pad structure between the inner tank and the outer shell, but it cannot effectively solve the problem of large heat leakage from the support due to the small distance between high-vacuum multi-layer heat insulation 2) The stainless steel casing structure between the inner and outer heads is difficult to manufacture, the distance between the inner and oute

Abstract

The high vacuum heat insulating low temperature liquefied gas storing tank includes frame and tank body. The tank body consists of outer casing, inner container and combined support structures connecting the outer casing and the inner container. The combined support structures are set between the inner sealing head and outer sealing head on two ends of the tank to bear the radial load and the axial load with great bearing force. The heat conducting area between the inner container and the outer casing is small, and the inner container has great effective loading volume.

Description

technical field [0001] The present invention relates to a low-temperature liquefied gas storage and transportation equipment, and more specifically relates to a high-vacuum heat-insulated low-temperature liquefied gas storage tank, which may be a tank truck or a tank container suitable for efficiently transporting low-temperature liquefied gas. The present invention realizes that the impact force and the temperature change of the carrier medium that the low-temperature liquefied gas storage and transportation equipment bears during the operation process meet the requirements of the low-temperature liquefied gas The requirements for storage and transportation, and the vacuum layer between the inner tank and the outer cylinder of the cryogenic container is the thinnest, and finally the loading rate of the cryogenic liquefied gas is maximized. The invention belongs to cryogenic engineering and cryogenic engineering [0002] technology field. Background technique [0003] The ...
