The water vapor recovery device is used to recover the water vapor generated by the boiler body 1.

[0023] The exhaust pipe 9 is provided so that the water vapor generated in the boiler body 1 can be discharged therefrom, and the water vapor in the conversion tube 10 is converted into water when encountering low temperature through the cooling water pipe 12, and the converted water can be recovered through the water collector 15, thereby achieving the recovery of water vapor.

[0024] Reference Figure 1 and Figure 2 In a preferred embodiment, a door 2 is provided at the lower right end of the boiler body 1, a heating chamber 3 is provided at the lower end of the boiler body 1, a partition device 4 is fixedly installed at the middle end of the boiler body 1, a chimney 5 is fixedly installed at the upper end of the middle of the partition device 4, a water collecting chamber 6 is provided at the upper end of the boiler body 1, a water inlet pipe 7 is provided at the upper left end of the boiler body 1, and a water outlet pipe 8 is fixedly installed at the left end of the middle of the boiler body 1.

[0025] In this embodiment, the water collecting bin 6 is filled with water through the water inlet pipe 7, fuel is added to the heating bin 3 for heating through the box door 2, and the ash is discharged through the chimney 5 during the heating process. After the water is heated, the water can be discharged through the water outlet pipe 8.

[0026] Reference Figure 3 and Figure 4 In a preferred embodiment, a cooling water pipe 12 surrounds the outer surface of the conversion tube 10 , the upper portion of the cooling water pipe 12 is set as a water inlet 13 , the lower portion of the cooling water pipe 12 is set as a water outlet 14 , and the water outlet 14 is connected to the water inlet pipe 7 .

[0027] In the present embodiment, during the process of heating water, water vapor will appear at the upper end of the boiler body 1, and the water vapor will float into the conversion tube 10. Cold water will be injected into the cooling water pipe 12 through the water inlet 13.

At the same time, after the water in the cooling water pipe 12 flows through the conversion tube 10, the water temperature changes, and it flows into the water collection tank 6 through the water outlet 14 and the water inlet pipe 7, and is recycled to save a certain amount of water resources.
