High-protecting-performance LNG low temperature storage tank convenient to move

Abstract

The invention belongs to the technical field of LNG low temperature storage tanks and particularly relates to a high-protecting-performance LNG low temperature storage tank convenient to move. A tankbody, a corner force bearing framework playing a protecting and hoisting role around the tank body, a liquid level monitoring device, a self-supercharging device, a leakage monitoring device, a PLC control device and a cold insulation device are included; universal wheels are arranged at the bottom end of the corner force bearing framework; the corner force bearing framework is arranged around thetank body, and plays the tank body protecting and hoisting role; the corner force bearing framework is provided with the universal wheels, movement is convenient, filling is easy and convenient, andthe safety risk is greatly reduced; the leakage monitoring device judges whether leakage happens or not by detecting the tank body temperature and outside environment temperature difference, the structure is simple, the monitoring precision is high, and the leaking risk is reduced; the liquid level monitoring device is used for monitoring the liquid level in the tank body, measuring is accurate, and the safety performance of the tank body is improved; the arrangement of the cold insulation structure facilitates keeping the low temperature environment in the tank body; and the overall structureis simple, design is reasonable, and the safety performance is high.

Description

technical field [0001] The invention belongs to the technical field of LNG low-temperature tanks, and in particular relates to a highly protective LNG low-temperature tank that is easy to move. Background technique [0002] At present, the transportation of natural gas at home and abroad mainly relies on pipeline transportation. For remote mountain villages or places with harsh environmental conditions, where pipelines cannot reach, LNG tank container transportation and transportation will be a good choice; currently domestic LNG low-temperature tank containers are still in the preliminary stage , technology, production, etc. are still being gradually optimized. There are two types of existing LNG low-temperature tanks, one is fixed and the other is mobile. After the fuel in the fixed LNG low-temperature tank is used up, it needs to be refilled with LNG filling pontoons or LNG low-temperature tankers. Filling is carried out, but the barge investment is too large, the cost i...

[0002] At present, the transportation of natural gas at home and abroad mainly relies on pipeline transportation. For remote mountain villages or places with harsh environmental conditions, where pipelines cannot reach, LNG tank container transportation and transportation will be a good choice; currently domestic LNG low-temperature tank containers are still in the preliminary stage , technology, production, etc. are still being gradually optimized

There are two types of existing LNG low-temperature tanks, one is fixed and the other is mobile. After the fuel in the fixed LNG low-temperature tank is used up, it needs to be refilled with LNG filling pontoons or LNG low-temperature tankers. Refueling, but the barge investment is too large, the cost is high, and there are safety hazards
