The invention discloses a
high pressure heat insulation gas storage pumping
compressed air energy storage system. Air in a water-gas common-cabin passes a
supercharger and then directly enters a gas storage vertical shaft, and pressure of gas in the water-gas common-cabin passes is kept stable and unchanged.
Potential energy and heat of
compressed air are stored at the same time because of the thermal
storage effect of the gas storage vertical shaft. At the stage of energy releasing, output
electric energy of the
system comprises the following two parts: for one part,
high pressure air with certain temperature in the vertical shaft enters a
turbine to do work through expansion; for the other part, water in the water-gas common-cabin pushes the
turbine to generate
electric energy, and the
energy density and operating efficiency of the
system are improved. As a heat insulating layer is arranged outside the gas storage vertical shaft, the air is high in temperature and flows through the
turbine and is expanded, then the temperature is reduced, the fact that the temperature in the water-gas common-cabin is low is guaranteed, and damage to the turbine caused by temperature rise of wateris avoided. The system stores
high pressure air through the gas storage vertical shaft, greatly reduces the
investment cost of a high pressure container, shortens the payback time, and improves the operating economy.
