Abstract

The invention discloses a mechanical full-bridge type circulating liquid gas compressing part and an energy storage system. The mechanical full-bridge type circulating liquid gas compressing part comprises a normal pressure liquid storage tank, a high pressure liquid storage tank, a first valve, a second valve, a third valve, a fourth valve, a fifth valve and a sixth valve, a first inlet / outlet, a second inlet / outlet, a tee joint and a pipeline. The bottom ends of the normal pressure liquid storage tank and the high pressure liquid storage tank are respectively provided with two openings, one opening at the bottom end of the normal pressure liquid storage tank is connected with one opening at the bottom end of the high pressure liquid storage tank through a pipeline, the first valve and the second valve, and the other opening at the bottom end of the normal pressure liquid storage tank is connected with the other opening at the bottom end of the normal pressure liquid storage tank through a pipeline, the second valve and the fourth valve. A pipeline between the first valve and the second valve and a pipeline between the second valve and the fourth valve are connected with the tee joint. Liquid is filled into the normal pressure liquid storage tank and the high pressure liquid storage tank. The high pressure liquid storage tank is serially connected with the pipeline through the fifth valve above the high pressure liquid storage tank. The first inlet / outlet is mounted above the normal pressure liquid storage tank, the second inlet / outlet is mounted above the high pressure liquid storage tank, and the sixth valve is mounted in the second inlet / outlet.

Description

technical field [0001] The invention relates to the technical field of energy storage, in particular to a mechanical full-bridge circulation liquid-gas compression component and an energy storage system. Background technique [0002] Energy is the driving force for human survival and development. With the development of society, human needs for energy are increasing. However, while human beings enjoy the benefits of economic development and scientific and technological progress brought by energy, they also encounter problems of energy security, energy shortage, and environmental pollution caused by excessive use of energy. The development of clean and renewable energy is conducive to solving the problems of energy security, energy crisis and environmental pollution. Due to the intermittent nature of solar energy and wind energy in renewable energy, how to use energy storage technology to "stitch" these intermittent energy sources and output them stably is the key to the dev...
