Working principle:
Gas compression processes:Hydraulically full in liquid piston 1, controller 10 opens the control of the first control valve the 1101, the 4th
Valve 1104 and the 5th control valve 1105 processed, it is living that low-pressure gas in low-pressure gas pipeline 2 by first port 101 is sent to liquid
In plug 1, the liquid in liquid piston 1 is flowed into pump turbine group 5 by the 4th pipeline and is done work by low-pressure gas, water
Pump turbine group after being sent into enough low-pressure gases in liquid piston 1, closes first in liquid again externally discharged water source 6
Control valve 1101, the liquid in pump turbine group the last 5 external water source 6 are sent in liquid piston 1, and compressed gas is to be compressed
After, the second control valve 1102 is opened, the gas of compression is sent in high-pressure gas pipelines 3.In the process, controller
10 temperature obtained in the liquid piston 1 that temperature sensor 7 obtains in real time can open third control valve if temperature is excessively high
1103, liquid cooling device 4 extracts the liquid of 1 lower part of liquid piston, and by liquid under the overhead stream of liquid piston 1, with pressure
The gas of contracting carries out heat exchange, meanwhile, liquid storage plate 106 is rotated, so that 106 liquid storage of liquid storage plate, increase compressed air and liquid
Contact area, and liquid forms liquid film between multiple filling layers, further increases and has arrived gas liquid interfacial area, keeps in liquid piston 1
Temperature be constant temperature.
Gas expansion process:Hydraulically full in liquid piston 1, controller 10 opens the control of the second control valve the 1102, the 4th
Valve 1104 and the 5th control valve 1105 processed, it is living that high pressure gas in high-pressure gas pipelines 3 by second port 102 is sent to liquid
In plug 1, after entering enough high pressure gas in liquid piston 1, it is swollen in liquid piston 1 to close 1102 gas of the second control valve
It is swollen, it pushes liquid through the 4th pipeline and is flowed into pump turbine group 5 and do manual work, pump turbine group discharges liquid again
Into external water source 6, after band expansion, the first control valve 1101 is opened, is fed gas into low-pressure gas pipeline 2.?
During this, the temperature that controller 10 is obtained in real time in the liquid piston 1 that temperature sensor 7 obtains can be with if temperature is excessively high
Third control valve 1103 is opened, liquid cooling device 4 extracts the liquid of 1 lower part of liquid piston, and by liquid from liquid piston 1
Under overhead stream, heat exchange is carried out with the gas of compression, meanwhile, liquid storage plate 106 is rotated, so that 106 liquid storage of liquid storage plate, increases compression
The contact area of air and liquid, and liquid forms liquid film between multiple filling layers, further increases and has arrived gas liquid interfacial area, keeps
Temperature in liquid piston 1 is constant temperature.
Based on thermostatically controlled compression air energy-storing apparatus described in the present embodiment, including:Liquid piston, low-pressure gas pipe
Road, high-pressure gas pipelines, liquid cooling device, pump turbine group, temperature sensor, the first cooling water circulation device, second
