As shown in fig. 1, the heat pipe heat recovery device based on water comprises a case 1, a heat transfer device 4, a hot water lift pump 5, a filter 7, an electric heater 13, and a partition plate 6, wherein the case 1 is divided into a heat taking cavity 2 and a waste water cavity 3 by the partition plate 6, and a hot water outlet 12 at the right side of the heat taking cavity 2 is connected with the electric heater 13 through the hot water lift pump 5; the waste water inlet 14 at the right side of the waste water chamber 3 is connected with the filter 7 through a pipeline. An insulating layer I16 is arranged on the case 1. A temperature measuring probe 23 of the temperature sensor 19 is arranged in the heat taking cavity 2. The heat transfer tubes 15 of the heat transfer device 4 are fixed to the center of the partition 6. The side wall of the case 1 is provided with a PLC 25. The PLC 25 is connected to the temperature sensor 19 and the electric heater 13.

As shown in fig. 2, the heat taking chamber 2 and the waste water chamber are communicated through a water purifier 8, a clean water inlet 9 on the left side of the heat taking chamber 2 is connected with a water outlet 10 of the water purifier 8 through a pipeline, and a waste water outlet 11 on the left side of the waste water chamber 3 is connected with a water inlet 24 of the water purifier 8 through a pipeline. The water purifier 8 is formed by connecting multi-stage filter elements in series end to end, the filter elements are sequentially arranged from low to high in precision, the multi-stage filter elements are shared to intercept dirt, the times of filter element blockage and manual pollution discharge and disassembly and washing are reduced, and the period of replacing the filter elements is prolonged. The water purifier 8 purifies water layer by layer through various filter elements, removes impurities, filters harmful substances such as bacteria heavy metal and the like, achieves the purpose of recycling waste water, and effectively saves water resources.

As shown in fig. 3, one end of the heat conducting pipe 15 of the heat transfer device 4 is connected with a heat exchange connector 17, and the heat exchange connector 17 is communicated with a heat exchange copper pipe 18; the other end of the heat transfer pipe 15 is connected to the evaporator 21. The heat exchange copper pipe 18 is provided with the aluminum fins 20, so that the heat transfer area is enlarged, the heat conduction effect is improved, and the heat exchange efficiency is increased. And an insulating layer II 22 is arranged on the heat conduction pipe 15. The evaporator 21 is internally packaged with a heat transfer medium which adopts distilled water and a catalyst in a ratio of 2: 1. The principle of evaporation heat transfer: after the evaporator 21 absorbs heat, the heat transfer medium is heated in the evaporator 21 to become gaseous, and enters the heat exchange copper pipe 18 through the heat conduction pipe 15 to release heat. The heat transfer area is enlarged through the aluminum fins 20, the heat conduction effect is improved, and the heat exchange efficiency is increased.

The waste water after cooling is purified by the water purifier 8, and the water is conveyed to the heat taking cavity 2 after purification, so that the waste water is recycled, and the water resource is effectively saved. The gas after the heat transfer medium is evaporated enters the heat exchange copper pipe 18 to release heat, and the water is heated. The aluminum fins 20 increase the heat transfer area, improve the heat conduction effect, and increase the heat exchange efficiency. The temperature probe 23 transmits the temperature of the heated water to the temperature sensor 19. The heated water enters the electric heater 13 through the hot water lift pump 5. The PLC 25 controls the heating process of the electric heater 13 according to the temperature information of the temperature sensor 19, adjusts the heating time, shortens the heating action time of the electric heater 13, saves electricity and improves the working efficiency.
