Energy release device, system and method of liquid gas storage tank

Abstract

The invention discloses an energy release device of a liquid gas storage tank, and relates to the technical field of storage and transportation of gas tanks. The energy release device of the liquid gas storage tank comprises a release valve body, a piston valve body and a check valve body, wherein the release valve body communicates with a gas outlet of a storage tank, the release valve body is used for supplying gaseous gas with the gas pressure of P0 into the release device, the release valve body preliminarily releases the energy of the gaseous gas with the gas pressure of P0 so as to reduce the pressure to P1, one end of the piston valve body communicates with the release valve body, the piston valve body is used for re-releasing the energy of the gaseous gas with the pressure of P1 toreduce the pressure to P2 and realizes the static pressure balance of the gas in the release device, one end of the check valve body communicates with the piston valve body, the other end of the check valve body communicates with a gas inlet of the storage tank, and the check valve body is used for re-releasing the energy of the gaseous gas with the gas pressure of P2 to reduce the pressure to P3and prevents the gaseous gas from flowing back. By adopting the technical scheme, the device has the advantages of reducing the gas evaporation rate, ensuring the stability of the storage tank and prolonging the storage time of liquid gas.

Description

technical field [0001] The invention relates to the technical field of gas tank storage and transportation, in particular to an energy release device, system and method for a liquid gas storage tank. Background technique [0002] Today, with increasing emphasis on environmental sanitation, controlling the discharge of pollutants is the consensus of all mankind. The application of green energy is put on the agenda. As an energy source, hydrogen has incomparable advantages: the combustion calorific value of hydrogen is high, and the energy per kilogram of hydrogen combustion is about 3 times that of gasoline, 3.9 times that of alcohol, and 4.5 times that of coke; the product of hydrogen combustion is water, Zero pollution to the environment; hydrogen is extremely abundant in the earth (prepared from seawater), and can be regenerated and reused. Therefore, hydrogen is the most ideal energy source for human beings, and has received extensive attention from countries all over t...
