7. the pumpless continuous high-pressure sprayer according to claim 6, wherein a first switch valve is connected in series between the filling inlet and the liquid discharge outlet, a first balance valve is connected in series with the pressure balance pipe, a second balance valve is arranged between the medium heat exchange channel and the liquid inlet exchange tank, a second switch valve is connected in series between the bottom outlet of the liquid inlet exchange tank and the inlet of the medium heat exchange channel, a third switch valve is connected in series with the pumping pipeline, a fourth switch valve is connected in series between the first spraying outlet and the spraying tank, and a fifth switch valve is connected in series between the second spraying outlet and the liquid inlet exchange tank.
8. The pumpless continuous high-pressure spray device as recited in claim 7, wherein the heat exchanger is an external heat exchanger capable of absorbing heat from the outside, the medium heat exchange passage is provided in the external heat exchanger, the heat source passage is an external heat source heat exchange passage, and water or air flow for supplying heat flows through the external heat source heat exchange passage.
9. A method of using the pumpless continuous high pressure sprayer according to any one of claims 2 to 8, comprising the steps of:
step a, presetting a liquid-phase low-boiling-point working medium in a storage tank, assembling a pump-pressure-free continuous high-pressure injection device, filling a liquid inlet exchange tank, an injection tank and each pipeline with a gas-phase low-boiling-point working medium, closing each valve, and opening a heat source channel of a heat exchanger for circulation;
B, communicating a storage tank with a liquid inlet exchange tank, allowing a liquid-phase low-boiling-point working medium to enter the liquid inlet exchange tank from the storage tank under the action of pressure difference, and cutting off the communication between the storage tank and the liquid inlet exchange tank after a set amount is reached;
c, communicating a gas phase port of the liquid inlet exchange tank with a medium heat exchange channel, boosting the pressure of the liquid inlet exchange tank, communicating a bottom outlet of the liquid inlet exchange tank with a liquid phase port of the medium heat exchange channel, allowing a liquid phase low boiling point working medium in the liquid inlet exchange tank to flow to the medium heat exchange channel of the heat exchanger under the action of gravity, heating and pressurizing the low boiling point working medium in the heat exchanger to form a high-temperature high-pressure gas phase low boiling point working medium, and then allowing the high-temperature high-pressure gas phase;
d, opening the first injection outlet and the second injection outlet, injecting high-temperature high-pressure gas-phase low-boiling-point working medium outwards, closing the second injection outlet after the air pressure in the liquid inlet exchange tank is reduced to a set value, communicating a pumping pipeline, and pumping and reducing the pressure of the liquid inlet exchange tank to form a low-pressure cavity;
And e, after the air pressure in the liquid inlet exchange tank is reduced to a set value, closing the pumping pipeline, and circularly repeating the steps b to d, wherein the liquid-phase low-boiling-point working medium in the storage tank intermittently flows into the liquid inlet exchange tank, the liquid inlet exchange tank alternately injects high-pressure gas-phase low-boiling-point working medium or pumps gas-phase low-boiling-point working medium, and the injection tank continuously injects high-temperature high-pressure gas-phase low-boiling-point working medium outwards.
