[0023] In this embodiment, a water tank 9 is fixedly connected to the upper surface of the support frame 1, and a water outlet pipe 10 is fixedly connected to one side of the outer surface of the water tank 9. One end of the water outlet pipe 10 is fixedly connected to the heat exchanger 4, and a water inlet pipe 11 is fixedly connected to one side of the outer surface of the heat exchanger 4. One end of the water inlet pipe 11 is fixedly connected to the boiler 2 and is in communication with the boiler 2.

[0024] In practical use, when the induced draft fan 5 is running, it can introduce the steam in the boiler 2 into the flue 3 and pass through the heat exchanger 4. The water source in the water tank 9 enters the heat exchanger 4 through the outlet pipe 10 and is heated by the heat exchanger 4. The heated water source then enters the boiler 2 through the inlet pipe 11, increasing the basic temperature of the water source when the boiler 2 is filled with water. After the steam passes through the induced draft fan 5, part of it is discharged along the flue 3 and drives the fan blades 8 and the rotating shaft 7 to rotate, so that the generator 6 can generate electricity and supply energy to the equipment, thereby realizing the multi-faceted utilization of waste heat.

[0025] In this embodiment, a diversion pump 12 is provided on one side of the outer surface of the water inlet pipe 11.

[0026] In practical use, the dredging pump 12 can easily draw water from the water tank 9 and pass it through the heat exchanger 4.

[0027] In this embodiment, an insulation box 13 is provided on one side of the outer surface of the water outlet pipe 10, and a heat dissipation vent 131 is provided on the upper surface of the insulation box 13.

[0028] In practical use, the insulation box 13 can provide a certain insulation and heating function for the water inlet pipe 11, and the heat dissipation port 131 can facilitate heat dissipation inside the insulation box 13.

[0029] In this embodiment, a heating wire 14 is provided on the inner wall of the heat preservation box 13, and the heating wire 14 is electrically connected to the generator 6.

[0030] In practical use, the generator 6 can supply power to the heating wire 14 so that the heating wire 14 can keep the water inlet pipe 11 warm, preventing the water source temperature in the water inlet pipe 11 from dropping after heat exchange due to the low temperature of the water inlet pipe 11 itself when the water source enters the water inlet pipe 11 after passing through the heat exchanger 4.

[0031] In this embodiment, a filter screen 15 is provided on the inner wall of the water tank 9.

[0033] In this embodiment, a water level alarm 16 is installed on the inner wall of the water tank 9.

[0034] In practical use, when the water level in water tank 9 drops to the level alarm 16, the level alarm 16 can sound an alarm, thereby reminding personnel to add water to water tank 9.

[0035] Working principle: During operation, the induced draft fan 5 draws steam from the boiler 2 into the flue 3 and through the heat exchanger 4. The filter screen 15 filters the water added to the water tank 9, reducing impurities. The water in the tank 9 is then pumped by the induced draft pump 12 through the outlet pipe 10 into the heat exchanger 4, where it is heated. The heated water then enters the boiler 2 through the inlet pipe 11, raising the base temperature of the water added to the boiler 2. When the water level in the tank 9 drops to the level alarm 16, the alarm is triggered. Device 16 can sound an alarm to remind personnel to add water to water tank 9. After steam passes through induced draft fan 5, a portion of it is discharged through flue 3 and drives fan blade 8 and rotating shaft 7 to rotate, enabling generator 6 to generate electricity and power the equipment, thus realizing the multi-faceted use of waste heat. Generator 6 can supply power to heating wire 14 so that heating wire 14 can insulate water inlet pipe 11, preventing the water temperature in water inlet pipe 11 from dropping after heat exchange due to the low temperature of water inlet pipe 11 itself when it enters water inlet pipe 11 after passing through heat exchanger 4.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
