The heating device consists of a heat storage tank 29, a heat exchange tank 18, a steam tank 15, a vaporization tank 12, and an ethanol tank 1 arranged in sequence from right to left. One side of the upper and lower parts of the heat storage tank 29 is respectively connected end to end with the heating pipeline 33, and the other side of the heat storage tank 29 is connected to the heat exchange tank 18. The middle position of the heat exchange tank 18 is connected to the middle position of one side of the steam tank 15 through a first pipeline 21. The middle position of the other side of the steam tank 15 is connected to the middle position of the vaporization tank 12 through a second pipeline 13. The upper and lower ends of the vaporization tank 12 are respectively connected to the upper and lower ends of the ethanol tank 1 through a first inner pipe 9 and a second inner pipe 10. The top of the ethanol tank 1 is externally connected to a water inlet pipeline 8 with a first water pump 7, and the upper and lower ends of the ethanol tank 1 on the side away from the vaporization tank 12 are respectively connected to the upper and lower ends of an external heat exchanger 2 through a first outer pipe 5 and a second outer pipe 6. A vaporization membrane assembly 35 is installed inside the vaporization tank 12.

[0017] The heat exchange tank 18 is internally provided with a heat exchange pipeline 30 bent in multiple sections. The head and tail of the heat exchange pipeline 30 are exposed outside the heat exchange tank 18 and are respectively connected to the upper and lower parts of the side of the heat storage tank 29.

[0018] The bottom of the heat exchange tank 18 is connected to the bottom of the ethanol tank 1 through a recovery pipeline 25, and a recovery tank 26, a second water pump 27, and a valve 28 are respectively installed on the recovery pipeline 25.

[0019] Circulation pumps are provided on the second outer pipe 6, the second inner pipe 10, the heat exchange pipeline 30, and the heating pipeline 33 of the ethanol tank. The circulation pumps are respectively a fourth circulation pump 3, a first circulation pump 11, a second circulation pump 31, and a third circulation pump 32. Valves are provided on the first outer pipe 5, the second pipeline 13, and the first pipeline 21. The valves are respectively a third valve 4, a first valve 14, and a second valve 22.

[0020] The position of the heat exchange tank 18 near the top is connected to an air extraction pipeline 20 with an air extraction pump 19, and the position of the heat exchange tank 18 near the bottom is connected to an air pressure pipeline 24 with an air compressor 23. The position of the steam tank 15 near the top is connected to a vacuum pipeline 17 with a vacuum pump 16. Multiple groups of radiators 34 are installed on the heating pipeline 33.

[0021] The working principle and process of the present utility model are as follows:

[0022] The vaporization membrane assembly in the utility model is formed by bonding diaphragms, and liquid can flow inside the diaphragm. The diaphragm is a modified diaphragm with tiny gaps on its surface, and gas can pass through these gaps in the diaphragm more easily. Under certain pressure, temperature and membrane surface area conditions, ethanol inside the vaporization membrane assembly will evaporate into gas faster and pass through these gaps. The temperature difference between day and night outdoors in the north is large, so the low-temperature heat outdoors during the day can be collected by a heat exchanger and stored in an ethanol tank, so that the ethanol liquid initially has a certain temperature, and then the ethanol liquid in the vaporization membrane assembly flashes through the internal and external pressure difference. Evaporation takes away the heat in the liquid, so that the saturated steam with heat passes through the gaps on the surface of the diaphragm and enters the heat exchange tank, and the saturated steam with heat is further compressed to increase the steam temperature in the heat exchange tank. Finally, heat exchange is performed to allow a more stable liquid water to absorb the temperature and circulate in the heating pipe.

[0023] At the beginning, all equipment is in a closed state. When working normally, the fourth circulation pump 3 and the third valve 4 are opened and operated during the day, and the ethanol liquid in the ethanol tank 1 continuously circulates between the ethanol tank 1 and the external heat exchanger 2, and the ethanol liquid exchanges heat with the outside. When the temperature drops at night, the fourth circulation pump 3 and the third valve 4 are closed, and the first circulation pump 11 is opened. Under the action of a certain water pressure of the first circulation pump 11, the ethanol liquid that has absorbed heat from the outside during the day circulates between the ethanol tank 1 and the vaporization membrane assembly 35 in the vaporization tank 12. The ethanol liquid with a certain temperature and pressure contacts one side of the vaporization membrane. At this time, the vacuum pump 16 is turned on to evacuate the inside of the steam tank 15. Since the second pipe 13 connects the steam tank 15 and the vaporization tank 12, the other side of the vaporization membrane that does not contact the ethanol liquid is at low pressure. Therefore, the ethanol liquid evaporates and vaporizes under the pressure difference on both sides of the vaporization membrane and passes through the gap on the surface of the vaporization membrane to collect The ethanol vapor in the steam tank 15 has a certain temperature because evaporation takes away heat. After a certain amount of ethanol vapor is collected, the vacuum pump 16 and the first valve 14 are closed, the second valve 22 is opened, and the vacuum pump 19 is operated to collect the ethanol vapor in the steam tank 15 into the heat exchange tank 18. After the collection is completed, the second valve 22 and the vacuum pump 19 are closed, and the ethanol vapor in the heat exchange tank 18 is compressed by the air compressor 23 to increase its temperature. The second circulation pump 31 and the third circulation pump 32 are operated to continuously exchange heat between the liquid water in the heat storage tank 29 and the high-temperature ethanol vapor, and the hot water after heat exchange is circulated in the heating pipe 33, and the indoor heating is provided by the radiator 34 on the heating pipe 33. The ethanol condensed by the cold is collected in the recovery tank 26. After a certain amount is collected, the valve 28 is opened, and the first water pump 27 is operated to make it flow back to the ethanol tank 1 through the recovery pipe 25.
