A hydrate pressurization and circulation system

Abstract

The invention discloses a hydrate pressurization and circulation system which comprises a gas-liquid mixing tank, a transfer pump, a hydrate generator, two low-pressure cold sources, a gas-liquid separator, two hydrate decomposers, a heat source, a high-pressure gas storage tank, a pressure-relief valve, a three-way valve, a circulating liquid pump and a plurality of one-way valves; the gas-liquid mixing tank is connected with the hydrate generator after mixing gas and liquid; the hydrate generator is connected with the gas-liquid separator after being cooled by a first low-temperature cold source; the serum outlet of the gas-liquid separator is connected with the two hydrate decomposers, and the gas outlet of the gas-liquid separator is connected with the gas inlet pipe of the gas-liquid mixing tank; the high-pressure gas outlets of the two hydrate decomposers are connected with a high-pressure gas storage tank through the one-way valves, and the circulating liquid outlets are connected with the gas-liquid mixing tank by the circulating liquid pump; the high-pressure gas storage tank is connected with the low-pressure gas inlet of the gas-liquid mixing tank by the pressure-relief valve; the gas-liquid mixing tank is a low temperature and constant pressure box body, and can keep a critical state which is generated by hydrate. According to the hydrate pressurization and circulation system, the pressurization and continuous circulation effects can be realized.

Description

technical field [0001] The invention relates to a hydrate circulation system, in particular to a circulation system with a pressurization function, which can be applied to refrigeration cycles and belongs to the field of new energy utilization. Background technique [0002] At present, in the field of engineering, gas boosting is mainly realized by using an air pump or a compressor to consume external power consumption. The pressure at the end of compression is high, and the required pressure difference is large, which will cause problems such as low machine efficiency, complicated structure, and increased cost. Moreover, the external mechanical drive will bring a certain amount of noise and vibration, which will affect its application in production and life. At present, hydrate technology has attracted more and more attention, and the research on hydrate mainly focuses on how to quickly and efficiently produce it and apply it to practical problems such as cold storage, sto...
