[0046] Reference Figures 1-7 A waste heat recovery and energy-saving device for a stenter includes a machine base 1, a conveyor belt 11 inside the machine base 1, the conveyor belt 11 being a conveying device driven by a motor in the prior art, used to carry the material to be stented, and is heated and stented during the movement inside the machine base 1; a first fan component 2 is provided on the top of the machine base 1, the first fan component 2 being a fan driven by a motor in the prior art, the air inlet end of the first fan component 2 being connected to the inside of the machine base 1 through a pipeline, the first fan component 2 being able to suck up the high temperature waste gas inside the machine base 1;

[0047] The machine 1 is also equipped with a water tank 3, which is used to balance the water temperature. The water tank 3 is connected to a heat exchanger 4, and an air inlet pipe 41 is installed on the heat exchanger 4. The air inlet pipe 41 is connected to the air outlet of the first fan component 2, so that the gas inside the machine 1 is connected to the heat exchanger 4 through the first fan component 2 and the air inlet pipe 41. The exhaust gas drawn from the machine 1 is transported to the heat exchanger 4 through the cooperation of the first fan component 2 and the air inlet pipe 41, avoiding the direct discharge of exhaust gas and completing the recovery of waste heat.

[0048] A support 411 is provided on the air inlet pipe 41, and the interior of the air inlet pipe 41 is connected to the interior of the support 411. A spray seat 5 is provided inside the support 411, and a spray nozzle 51 is provided inside the spray seat 5. Several spray nozzles 51 are provided, and the several spray nozzles 51 are distributed at intervals along the length of the spray seat 5, so as to achieve full coverage spraying of the gas located in the support 1 and avoid the problem of dead flow. The spray seat 5 has a liquid inlet interface 52 extending to the outside of the support 411. A water pump component 6 is provided on the water tank 3. One end of the water pump component 6 is connected to the water tank 3, and the other end is connected to the liquid inlet interface 52.

[0049] The heat exchanger 4 is also connected to the second fan component 7 via a pipeline. The machine base 1 is also equipped with a combustion box 8. The second fan component 7 is connected to the combustion box 8. The combustion box 8 contains a burner equipped with an ignition electrode and a flame detector. Air and fuel are mixed in an appropriate ratio through a premixing device to ensure complete combustion. When the exhaust gas is in the combustion box 8, it can act as an auxiliary combustion gas to improve combustion efficiency. The combustion box 8 is equipped with a pipeline connected to the inside of the machine base 1. A gas circulation channel is formed by the cooperation of the first fan component 2, the heat exchanger 4, the second fan component 7 and the combustion box 8. The gas circulation channel is a closed-loop design, which can reduce the contact between the exhaust gas and the outside air, thus reducing the need for increased heating. After the exhaust gas recovers heat through the heat exchanger 4, part of the gas passes through the combustion box 8 to supplement oxygen or burn residual organic matter, and finally returns to the machine base 1 for recycling.

[0050] A filter seat 412 is also provided on the air inlet pipe 41. The filter seat 412 has a receiving groove that communicates with the inside of the air inlet pipe 41 and a filter component 9 is installed thereon. The filter component 9 includes a filter screen 92, which is located in the receiving groove. The filter component 9 also includes a cover plate 91, on which the filter screen 92 is installed. The cover plate 91 has a handle, which makes it easy to hold and pick up the cover plate 91. When the filter screen 92 is located in the receiving groove, the cover plate 91 abuts against the top end face of the filter seat 412. The filter component 9 is located between the heat exchanger 4 and the spray seat 5. When the gas is about to enter the heat exchanger 4, it needs to pass through the filter component 9 for further filtration of gas impurities.

[0051] The first fan component 2, water tank 3, heat exchanger 4, water pump component 6, and second fan component 7 are each provided with two sets and symmetrically distributed at both ends of the top of the machine base 1. By setting two sets, the two systems can operate independently or work together, thereby improving efficiency, sharing the gas pressure, improving stability, and maintaining some functions of the other set when one set fails.

[0052] Based on the above structure, the material to be tested is conveyed to the machine 1 via conveyor belt 11, and heating is performed inside the machine 1. The waste gas generated by heating is extracted by the first fan component 2 and conveyed to the air inlet pipe 41. When the waste gas flows towards the heat exchanger 4 in the air inlet pipe 41, it passes through the support 411 and the filter seat 412. When the gas is in the support 411, the water pump component 6 conveys the liquid in the water tank 3 to the spray seat 5 through the liquid inlet interface 52, and sprays the liquid through the spray nozzle component 51. The water mist generated by the liquid comes into contact with the waste gas, which can adsorb the attached particulate matter and dissolved acidic gases in the waste gas, completing the preliminary impurity removal and filtration of the waste gas. The water tank 3 and the heat exchanger 4 The connection ensures that the temperature in the water tank 3 will not have an excessive impact on the gas temperature. The sprayed exhaust gas flows into the filter seat 412, and the filter screen 92 in the filter component 9 filters the exhaust gas again. Thus, the gas in the heat exchanger 4 undergoes two filtration operations, and is adjusted to a suitable temperature by the heat exchanger before being transferred to the combustion chamber 8 for combustion. Finally, the gas is transported back to the machine 1 through the combustion chamber 8. The gas is recycled through the cooperation of the first fan component 2, the heat exchanger 4, the second fan component 7, and the combustion chamber 8. The spray seat 5 and the filter component 9 can filter and remove impurities from the gas, thereby recovering the gas heat energy, improving efficiency, and reducing economic losses.

[0053] Both the first fan component 2 and the second fan component 7 mentioned above are centrifugal fans driven by motors in the prior art. The first fan component 2 is used to absorb the exhaust gas in the machine 1, while the second fan component 7 is used to absorb the gas that has undergone heat exchange through the heat exchanger 4.

[0054] In one embodiment, reference is made to Figure 1 and Figure 4 The machine tool 1 is equipped with two sets of symmetrically distributed heat storage chambers 12. The conveyor belt 11 is located between the two sets of heat storage chambers 12. The heat storage chambers 12 can store the radiant heat and waste heat of the gas inside the machine tool. The heat storage chambers 12 are provided with flow ports 121. Several flow ports 121 are provided and distributed at intervals along the length of the heat storage chambers 12. Through the cooperation of the flow ports 121, the two sets of heat storage chambers 12 are interconnected. Through the flow ports 121, the heat inside the machine tool 1 can be evenly distributed and the heat can be circulated between the two heat storage chambers to ensure the temperature balance inside the machine tool 1.

[0055] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 5 The bottom of the cover plate 91 is also equipped with filter cloth 93, which is arranged in two sets with intervals. The filter screen 92 is located between the two sets of filter cloth 93. The filter cloth 93 can achieve multi-layer filtration of exhaust gas before it enters the heat exchanger, thereby improving filtration efficiency and protecting the heat exchanger 4.

[0056] In one embodiment, reference is made to Figures 1-4 The heat exchanger 4 is equipped with a housing 42. Pipes and air inlet pipes 41 pass through the housing 42 and are connected to the heat exchanger 4. The housing 42 can enclose the heat exchanger 4 to form a closed space, reducing the heat exchange loss between the heat exchanger 4 and the environment. The housing 42 is provided with an air inlet opening 421. A one-way valve is installed in the air inlet opening 421, and fresh air from outside is supplied through the air inlet opening 421 to achieve pressure balance. The one-way valve can prevent backflow of gas, which could lead to pollution of the external environment.
