It is changed into low pressure water flow eventually and enters low pressure cistern B.
One small pump is installed between the screw-rod air compressor C and low pressure pipeline D4, is taken out low pressure water by small pump
Enter in air compressor machine.
The pressure vessel A original states are full water, as the constant compressed air of pressure is constantly moved into most at last in tank
Water all discharges the compressed air for being changed into isometric fixed pressure.
Flowed through in the gas pipeline D1 for gas-liquid mixture, be transferred in pressure vessel A and complete gas-liquid separation again.
The screw-rod air compressor C, which mixes the air of normal pressure with water, to be compressed, and is cooled down by water to compressed air
With lubrication, compression efficiency is improved.
The system initial period drives hydraulic turbine operating by motor, and rotational speed of water turbine will be protected after synchronous rotational speed is reached
Hold invariable, pass through the water yield of flow valve F pressure of pressure vessel A.
The pressure vessel A is stored using compressed air constant pressure, that is, while flowing into certain volume compressed air, it is necessary to arrange
Go out isometric high pressure water so that compressed air will not be expanded or further compressed in pressure vessel A.
The hydraulic turbine G is changed to the bidirectional reversible formula hydraulic turbine, the motor M is changed to generator, realizes system
Antikinesis of uniting generates electricity.
The beneficial benefit of the present invention includes the following aspects：
(1) present invention is designed improvement to traditional screw-rod air compressor, with motor, the coaxially connected acquisition of the hydraulic turbine
Power, avoids high pressure water in tank and is directly discharged into energy dissipation caused by low pressure cistern, improve the compression efficiency of system.
(2) present invention replaces the compressed oil of routine to mix compression with air with water, eliminates conventional screw air compressor machine oil circuit
Design, compressed mixture, which is passed directly into pressure vessel, voluntarily to be separated, and is not required to install single gas-water separation equipment additional, reduce
The complexity of system, saves manufacture cost.
(3) present invention use liquid occupy-place technology, the cooperation with flow valve, the flow of guarantee compressed air and water phase all the time
Deng compression and the expansion process of air will not occur in air container, remain constant pressure storage state, sustainable offer constant pressure
Source of the gas.
