They are only for the convenience of describing the embodiments and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments.

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown in the figure, this embodiment of the invention proposes an energy-saving device for reusing waste heat in glass production, including a pair of conversion components 1. Each conversion component 1 includes a water storage tank 11, an evaporation channel 12, an installation groove 13, an air inlet 14, an air inlet pipe 15, an air outlet pipe 16, a pressurization pump 17, a water inlet pipe 18, a water outlet pipe 19, an evaporation reaction platform 110, a controller 111, a circulation pipe 112, a reaction chamber 113, a placement hole 114, an air outlet 115, and a spiral pipe 116.

[0035] In this embodiment of the invention, the water storage tank 11 has an installation groove 13 inside. An evaporation channel 12 is connected to one side of the water storage tank 11, and the interior of the evaporation channel 12 is connected to the interior of the water storage tank 11. A water inlet pipe 18 is provided at the bottom of one side of the water storage tank 11, and the water inlet pipe 18 is connected to the water flow for evaporation. Similarly, a water outlet pipe 19 is connected to the upper part of one side of the water storage tank 11, and the water outlet pipe 19 can discharge water. A pressure pump 17 is connected to the outside of the water storage tank 11, and the pressure pump 17 can make the water flow from the water storage tank 11 quickly enter the lower part of the evaporation channel 12 and squeeze it from the bottom to the top of the evaporation channel 12. A spiral pipe 116 is wound around the outside of the evaporation channel 12, and the spiral pipe 116 is attached to the outer surface of the evaporation channel 12. An air inlet pipe 15 is connected to the bottom of the spiral pipe 116, and an air outlet 14 is connected to the outside of the air inlet pipe 15. The air outlet 14 can input filtered high-temperature exhaust gas. The high-temperature exhaust gas enters the air inlet pipe 15 from the air outlet 14, and then enters the spiral pipe 116 from the air inlet pipe 15. Since the spiral pipe 116 is wrapped around the outer surface of the evaporation channel 12, the water flow in the evaporation channel 12 can be heated. As the spiral pipe 116 heats the evaporation channel 12, the water flow inside can evaporate into water vapor and collect at the top of the water storage tank 11. By wrapping the spiral pipe 116 around the outer surface of the evaporation channel 12, the contact area with the evaporation channel 12 can be greatly increased, thereby improving the reaction efficiency.

[0036] An evaporation reaction platform 110 is located above the water storage tank 11 and is connected to the water storage tank 11. Water vapor at the top of the water storage tank 11 can enter the evaporation reaction platform 110. Multiple sets of circulation pipes 112 are installed inside the evaporation reaction platform 110. A controller 111 is located on the side of the evaporation reaction platform 110 and can control the opening and closing of the circulation pipes 112. Water vapor entering the evaporation reaction platform 110 will enter the circulation pipes 112, which can pressurize the gas entering them. The pressurization through multiple sets of circulation pipes 112 can achieve a higher pressure. A reaction chamber 113 is connected to the top of the evaporation reaction platform 110. An outlet 115 is located inside the reaction chamber 113, and the lower part of the outlet 115 is connected to the circulation pipes 112. Finally, the evaporated gas will pass through the circulation pipes 112 and exit from the outlet 115. 5. The gas enters the reaction chamber 113. A gas outlet pipe 16 is connected to the top of the spiral pipe 116. The top of the gas outlet pipe 16 is also connected to the gas outlet 115 in the reaction chamber 113. The fan blade 34 in the power generation component 3 is located above the gas outlet 115. So when the gas is discharged from the gas outlet 115, it can drive the fan blade 34 above the gas outlet 115 to rotate, thereby causing the power generation component 3 to generate electricity. The high-temperature gas is discharged to the fan blade 34 through the conversion component 1. The spiral pipe 116 evaporates the water in the evaporation channel 12 into water vapor. The water vapor is also discharged from the gas outlet 115 to the fan blade 34. Finally, it can drive the fan blade 34 to rotate at high speed and generate electricity. This invention makes full use of the high-temperature gas generated after glass production. The waste gas can be reused to generate electricity and fed back to the glass production. It makes full use of resources and saves energy.

[0039] In this embodiment of the invention, a screw 32 is provided at one end of the generator 31. The screw 32 passes through the placement hole 114 in the reaction chamber 113. A rotating shaft 33 is fixedly connected to one end of the screw 32. Multiple sets of fan blades 34 are provided on the outer surface of the rotating shaft 33. A rotating shaft 35 is fixedly connected inside the rotating shaft 33. The rotating shaft 35 is movably connected to the inner wall of the reaction chamber 113. The fan blades 34 are located directly above the air outlet 115. High-temperature and high-pressure gas is blown out of the air outlet 115 to the fan blades 34, which can drive the fan blades 34 to rotate rapidly. During the rotation of the fan blades 34... It can drive the screw 32 to rotate, which ultimately acts on the generator 31. A first pipe 36 and a second pipe 37 are provided on the outside of the generator 31. Both the first pipe 36 and the second pipe 37 are used to transmit electricity. The end of the first pipe 36 is connected to the booster pump 17. The lower part of the generator 31 is connected to the fixing frame 38, which is connected to the conversion component 1. The first pipe 36 can provide power support to the booster pump 17, while the other second pipe 37 is connected to an external energy storage device and provides power support for the glass production process, which not only reduces carbon emissions but also saves energy.

The gas conveying component 2 is disposed at the lower part of the conversion component 1. The gas conveying component 2 is configured to filter the exhaust gas from glass production and convey gas to the conversion component 1.

[0041] The gas delivery assembly 2 includes a gas collection chamber 21, a filter chamber 22, a filter screen 23, a servo motor 24, a ventilation shaft 25, a baffle 26, a ventilation strip 27, a pressure boosting valve 28, and a support plate 29.

[0042] In this embodiment of the invention, a filter chamber 22 is provided at the upper part of the gas collection chamber 21, and a pressure boosting valve 28 is provided on the side of the gas collection chamber 21. The pressure boosting valve 28 is fixed to the side of the gas collection chamber 21 by a support plate 29. The lower part of the gas collection chamber 21 is connected to the glass production exhaust device. The exhaust gas will first enter the gas collection chamber 21, and the pressure boosting valve 28 on the side can accelerate the flow rate of the gas in the gas collection chamber 21. The exhaust gas enters the filter chamber 22 from the gas collection chamber 21.

[0043] A ventilation shaft 25 is provided inside the filter chamber 22, and a ventilation strip 27 is provided inside the ventilation shaft 25. The lower gas collection chamber 21 of the ventilation shaft 25 is connected. The exhaust gas entering from the gas collection chamber 21 will be discharged through the ventilation strip 27. Baffles 26 are fixedly connected to both sides of the ventilation strip 27 to block the flow of gas. Filter screens 23 are provided on both sides of the filter chamber 22. The exhaust gas blocked by the baffles 26 will flow to the position of the filter screen 23. The filter screen 23 can remove the residual impurities in the exhaust gas. The filter screen 23 is connected to the gas inlet 14 of the conversion component 1. Finally, the exhaust gas enters the gas inlet 14 after being filtered by the filter screen 23, and then enters the spiral pipe 116 for steam reaction. This process can be repeated to continuously recover and treat the exhaust gas in the glass production process.
