Pass to heat storage can（7）In medium, pass through radiator（6）In coolant media constantly circulate, heat collector is collected
Heat be stored in heat storage can（7）In；
3rd, in heat storage can（7）Middle pressure sensor carries out pressure and detects in real time, when detecting pressure in 1.5MPa-2MPa, beats
Open level-one Venturi tube（8）On control valve A（13）, control valve B at this time（14）It is closed, heat storage can（7）In Jie
Matter passes through control valve A（13）Into level-one Venturi tube（8）, enter back into two level Venturi tube（11）, level-one Venturi tube（8）'s
The level-one generator of discharge end setting（10）High speed by medium impeller（9）Rotation generates electricity, and flows through level-one text
Venturi（8）Medium again pass by two level Venturi tube（11）, two level Venturi tube（11）Discharge end setting two level hair
Motor（12）High speed by medium impeller（9）Rotation generates electricity, and works as heat storage can（7）Internal pressure is in 1.2MPa
When, open control valve B（14）, control valve A at this time（13）In opening state, level-one generator（10）And secondary generator（12）
It generates electricity simultaneously, works as heat storage can（7）When internal pressure is in 1.0MPa, closing control valve A（13）, control valve B at this time（14）It is in
Opening state controls two level Venturi tube（11）With heat storage can（7）Between compressor（5）, the low speed after generator is exported
Medium is in compressor（5）Under the action of refill heat storage can（7）In, level-one generator at this time（10）And secondary generator（12）
On impeller（9）Rotation is and at the same time generate electricity, by control valve B after being vacuumized inside Venturi tube simultaneously（14）It closes,
Control valve A at this time（13）It is closed, power generation process is completed；
4th, above-mentioned 1-3 steps are repeated to carry out continuing power generation, and the DC conversion that generator is sent out is grid-connected after alternating current.
