[0031] See also Figure 1-4 As shown, in this embodiment, a high-temperature steam recycling device that is easy to maintain is provided, including a cover plate 3 and a heat exchange tank 1, and gourd sockets 11 are arranged around the cover plate 3. The gourd sockets 11 are used to cooperate with the plug rods 14. The plug rods 14 are installed around the upper end of the heat exchange tank 1. The plug rods 14 are arranged to be inserted into the gourd sockets 11. A limit plate 13 is arranged at the upper end of the plug rod 14. The limit plate 13 is arranged to limit the range of movement of the plug rod 14. Screw holes 12 are arranged at positions opposite to the upper side of the cover plate 3 and the upper side of the heat exchange tank 1. A fixing bolt 4 is rotatably installed inside the screw hole 12. A circulation pipe 19 is installed at the bottom end of the cover plate 3. The circulation pipe 19 is used to introduce the heat of the air into the water. The air inlet section and the air outlet section of the circulation pipe 19 are respectively installed with the air inlet pipe 5 and the air outlet pipe 6. The air inlet pipe 5 and the air outlet pipe 6 are installed on the upper side of the cover plate 3.

[0032] The application of one aspect of this embodiment is: when high-temperature steam is used to sterilize medical waste, the exhaust gas after use is introduced into the circulation pipe 19 through the air inlet pipe 5, and then discharged through the air outlet pipe 6. After the hot air enters the circulation pipe 19, it will exchange heat with the water inside the heat exchange tank 1. The air is cooled by water, and the waste heat in the exhaust gas can be recovered and reused. When the cover plate 3 and the heat exchange tank 1 are installed, the circulation pipe 19 is introduced into the heat exchange tank 1 so that the limit plate 13 passes through the large-diameter end of the gourd socket 11. When the cover plate 3 is rotated, the insertion rod 14 is inserted into the small-diameter end of the gourd socket 11. The insertion rod 14 is restricted in the gourd socket 11 by the limit plate 13, and then fixed by the fixing bolt 4. When the interior of the heat exchange tank 1 needs to be repaired and maintained, only a small amount of fixing bolts 4 need to be removed to remove the cover plate 3 and the circulation pipe 19, which is very convenient and quick.

[0033] In this embodiment, a heat insulation plate 20 is provided inside the heat exchange tank 1. The heat insulation plate 20 is attached to the inside of the heat exchange tank 1 by adhesive. The heat insulation plate 20 is provided to increase the heat insulation effect of the heat exchange tank 1 to prevent heat leakage during use, which may cause the temperature of the outer surface of the heat exchange tank 1 to rise.

[0034] In this embodiment, a safety valve 17 is provided at the upper end of the cover plate 3. The safety valve 17 is fixedly installed at the upper end of the cover plate 3 by bolts. The setting of the safety valve 17 is used to balance the air pressure inside the heat exchange tank 1 to prevent the high air pressure or low air pressure from affecting the discharge and import of water inside the heat exchange tank 1.

The setting of the gas-liquid separator 16 can separate water and air in the steam to prevent water vapor from condensing inside the circulation pipe 19 and blocking the circulation of air.

[0038] In this embodiment, a rubber pad 7 is provided at the bottom end of the cover plate 3, and the rubber pad 7 is adhered to the bottom end of the cover plate 3 by adhesive. The rubber pad 7 is relatively soft in texture. When the cover plate 3 is installed on the upper side of the heat exchange tank 1, the gap between the cover plate 3 and the heat exchange tank 1 can be filled, so that the cover plate 3 and the heat exchange tank 1 are installed more tightly.

[0039] In this embodiment, a plurality of heat conducting plates 18 are evenly arranged on the upper side of the circulation pipe 19, and the heat conducting plates 18 are welded on the upper side of the circulation pipe 19.
