The input end of the air inlet fan 11 is connected to the middle of the first exhaust pipe 12 through the connecting pipe 18. When the air inlet fan 11 is started to work, the air discharged from the first exhaust pipe 12 is extracted through the connecting pipe 18 and discharged to the air inlet box 10 through the output end of the air inlet fan 11.

When the intake fan 11 is started and operates, the air discharged from the first exhaust duct 12 is extracted through the connecting pipe 18 and discharged to the intake air box 10 through the output end of the intake fan 11. The air flow then enters the interiors of a plurality of outlet ducts 15 through the first intake duct 13 and the second intake duct 14, and the air flow is discharged into the drying furnace body 1 through the plurality of outlet ducts 15 for reciprocating circulation. Water is discharged into the water inlet pipe 21, and the water flow enters the heat exchanger 2 through the interior of the water inlet pipe 21. The water flow is converted into hot water through the heat exchanger 2. When the air flow enters the interior of the intake air box 10, the temperature of the air flow rises through the heat exchanger 2 and then is discharged into the first intake duct 13 and the second intake duct 14. The water flow passes through the interior of the heat exchanger 2 and is then discharged through the outlet pipe 22. When the drying furnace body 1 extracts the air flow inside the first exhaust duct 12 through the connecting pipe 18, the air flow first passes through the middle of the filter screen opening 3, and the air flow is filtered by the filter screen opening 3 and then enters the interior of the connecting pipe 18. When the fan blades 17 are started, the air flow inside the drying furnace body 1 is sucked into the second exhaust duct 4 through a plurality of third exhaust ducts 41, then enters the first exhaust duct 12 through the second exhaust duct 4 and is discharged. At the same time, the first exhaust duct 12 discharges the dust and impurities inside the drying furnace body 1 through the dust suction port 42 at the end. The temperature inside the drying furnace body 1 is usually relatively high, and the temperature at the end of the first exhaust duct 12 is relatively low.
