The heat energy recycling device for a stenter can recycle and reuse the waste gas in the stenter, heat the fresh air entering the stenter, reduce the heating energy consumption of the fresh air in the stenter, and be more energy-saving. However, the heat exchange elements in some existing heat energy recycling devices for stenters are all heat exchange tubes. The fresh air flows through the inside of the heat exchange tubes, and the waste gas flows through the outside of the heat exchange tubes, enabling heat exchange. However, the waste gas flows through the heat exchange tubes and the inside of the device, and waste materials and residues in the waste gas are easily attached to the inner wall of the heat exchange tubes. After a long time of use, the heat exchange efficiency of the heat exchange tubes will decrease, and the heat exchange tubes need to be removed and cleaned regularly, which is very time-consuming and laborious.

The exhaust gas used by the stenter can be reused, and the heat energy of the exhaust gas can be fully utilized, so that the fresh air can be heated up, reducing the energy consumption required for heating the fresh air, reducing energy consumption, and conforming to the environmental protection concept.

[0031] As shown in Figure 7 , Figure 8 , Figure 9 the figure, the first end plate 211 and the second end plate 212 are triangular.

The first baffle 2114 is connected to the inner wall of the chassis 1. A first sealing plate 2113 is installed between two adjacent first end faces 2111. The first baffle 2114 divides the first chassis opening 11 into a first cavity 111 and a second cavity 112. The first baffle 2114 and the first sealing plate 2113 can completely separate the first cavity 111 and the second cavity 112.

Similarly, the second baffle 2124 is fixedly connected to the inner wall of the chassis 1 and, together with the second sealing plate 2123, completely separates the third cavity 121 and the fourth cavity 122. The first cavity 111 communicates with the fourth cavity 122, and the second cavity 112 communicates with the third cavity 121, enabling cross heat exchange between fresh air and exhaust gas.

[0033] More preferably, the ends of the first baffle 2114 and the second baffle 2124 away from the heat exchange plate 21 are both inclined upward, which can prevent water from entering the interior of the heat exchange plate 21 when the first cleaning assembly 3 at the top is cleaning, and can play a guiding role for the cleaning water.

[0034] The first cleaning assembly 3 is installed inside the chassis 1. The first cleaning assembly 3 is located above the heat exchange assembly 2. The first cleaning assembly 3 includes a first pipe group 31 and a second pipe group 32. The first pipe group 31 includes a first main pipe 311 and a plurality of first branch pipes 312. The second pipe group 32 includes a second main pipe 321 and a plurality of second branch pipes 322. One ends of the first main pipe 311 and the second main pipe 321 both extend out of the chassis 1. Steam can be introduced into the first main pipe 311, and clean water can be introduced into the second main pipe 321. A plurality of first branch pipes 312 and a plurality of second branch pipes 322 both extend along the length direction of the heat exchange plate 21.

The plurality of first spray heads 323 are arranged along the length direction of the second branch pipes 322. The first spray heads 323 can eject clean water to wash the stains on the heat exchange plate 21. A tray 5 is installed at the bottom of the chassis 1. The tray 5 is located below the heat exchange assembly 2. The tray 5 can receive the sewage washed off from the heat exchange assembly 2. The tray 5 is provided with a drain port 51. The center of the tray 5 is recessed downward. The drain port 51 is located at the center of the tray 5 and is used to discharge the sewage after flushing.

[0035] Such as Figure 3 、 Figure 7As shown, more preferably, the second exhaust gas outlet 23 is located above the second fresh air inlet 25, and the second fresh air outlet 26 is located above the second exhaust gas inlet 24. At least two partition plates 7 are installed inside the chassis 1, and the two partition plates 7 are respectively located at the upper ends of the second exhaust gas outlet 23 and the second fresh air outlet 26. At least a part of the first branch pipe 312 and the second branch pipe 322 penetrate through the partition plate 7 located above the second exhaust gas outlet 23. At least a part of the first spray head 323 and the air holes of the first branch pipe 312 are located above the second exhaust gas outlet 23. The first spray head 323 and the air holes located above the second exhaust gas outlet 23 can clean the heat exchange plate 21 part at the second exhaust gas outlet 23, and the cleaning water flow can flow along the heat exchange plate 21 into the tray 5. The partition plate 7 located at the upper end of the second fresh air outlet 26 can prevent the spray cleaning water from entering the third cavity 121, and at the same time, the partition plate 7 plays a role in supporting and fixing the first cleaning assembly 3.

[0036] This embodiment further includes a second cleaning assembly 4. The second cleaning assembly 4 includes a third pipe group 41.

Some of the second air holes face the heat exchange assembly 2, and the other part of the second air holes face the center of the inside of the tray 5. Since the first cleaning assembly 3 is located above the heat exchange assembly 2 and flushes from top to bottom, the stains flow down along the heat exchange plate 21 and are likely to remain at the lower end position of the heat exchange plate 21. The second cleaning assembly 4 can perform steam spraying on the bottom of the heat exchange assembly 2.

The first exhaust gas inlet 14 is installed with a third cleaning assembly 6. The third cleaning assembly 6 includes a third main pipe 61. The third main pipe 61 is provided with a plurality of second spray heads 611. The second spray heads 611 face the second exhaust gas inlet 24. Since there are often more stains adhered to the second exhaust gas inlet 24, the third cleaning assembly 6 can align with the second exhaust gas inlet 24 of the heat exchange assembly 2 and directly flush the second exhaust gas inlet 24. The second spray heads 611 are arranged along the third main pipe 61, and two adjacent second spray heads 611 are arranged in an angular dislocation manner, which can make the spraying angle larger. Air guiding plates 8 are installed in the first exhaust gas outlet 13 and the first fresh air outlet 16, which can guide the fresh air or exhaust gas to be sent outwards.

[0038] As Figure 2 、Figure 7 As shown, the first exhaust gas outlet 13, the first exhaust gas inlet 14, and the first fresh air outlet 16 are located on the side wall of the chassis 1. The first fresh air inlet 15 is located at the bottom of the chassis 1. A porous mesh plate is installed at the first fresh air inlet 15.
