Description

Technical Field

[0001] This utility model relates to the field of float glass technology, specifically to a float glass tin bath waste gas adsorption, purification, treatment, and recovery device. Background Technology

[0002] The float glass manufacturing process generates a large amount of waste heat, which, if not utilized, will lead to energy waste and environmental pollution. Therefore, the waste heat recovery and utilization device for the tin bath flue of float glass is mainly used to recover and utilize this waste heat to achieve the purpose of energy conservation and emission reduction. In the existing waste heat recovery and utilization device for the tin bath flue of float glass, debris and impurities inevitably enter the waste heat recovery device during the waste heat recovery process, which requires workers to disassemble and clean the device. This cleaning method is not only slow, but also increases the workload of workers.

[0003] A search revealed that prior art CN221854458U discloses a novel waste heat recovery and utilization device for the venting flue of a float glass tin bath. The device includes a base, with a waste heat recovery cylinder fixedly connected to the top right side of the base. An electric motor is fixedly connected to the bottom of the waste heat recovery cylinder. The drive end of the electric motor penetrates the inner wall of the waste heat recovery cylinder and is fixedly connected to a fixing rod. Hydraulic push rods are rotatably connected to opposite ends of the inner walls of the fixing rods, and rotating plates are rotatably connected to opposite ends of the hydraulic push rods. This invention can clean residual debris and impurities on the inner wall of the heat dissipation tube, eliminating the need for workers to disassemble and clean the device, improving cleaning efficiency, reducing workload, and allowing the cooling air to be heated by the high-temperature heat in the exhaust gas within the air chamber. Simultaneously, the cooling air provides cooling and protection for the tin bath venting, extending the device's service life.

[0004] However, the above-mentioned device has the following problems when in use: the air flow channel inside the heat dissipation inner tube is a straight structure, which means that the exhaust gas will be in a fast state when it flows, which greatly increases the time for heat exchange with the cold air, resulting in a much longer time for the cold air temperature to rise, slow heating and inconvenience of use. Utility Model Content

[0005] The purpose of this utility model is to provide a float glass tin bath waste gas adsorption purification treatment and recovery device to solve the problem that the air flow channel inside the heat dissipation inner tube of the existing waste gas recovery and utilization device is a straight structure, which causes the waste gas to flow in a fast state, greatly increasing the time for heat exchange with cold air, resulting in a long time for the cold air temperature to rise, slow heating and inconvenience.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a float glass tin bath waste gas adsorption purification treatment and recovery device, including a heat dissipation inner tube, in which a plurality of adsorption packing balls are arranged, and also includes auxiliary components;

[0007] The auxiliary components include a waste heat recovery tank, an exhaust gas inlet pipe, a cold air inlet pipe, a hot air outlet pipe, a first spiral blade, an exhaust plate, a hanging column, a second spiral blade, and a storage component. The bottom of the heat dissipation inner tube is welded to the inner bottom of the waste heat recovery tank to form a jacketed cavity structure, and its top is slidably connected to the sealing cover of the waste heat recovery tank. The exhaust gas inlet pipe is slidably connected to the waste heat recovery tank and threadedly connected to the air inlet of the heat dissipation inner tube. The cold air inlet pipe is welded to the bottom side of the waste heat recovery tank and communicates with the jacketed cavity formed by the waste heat recovery tank and the heat dissipation inner tube. The hot air outlet pipe is located on the top side of the waste heat recovery tank and communicates with the storage component. The first spiral blade is detachably connected to the sealing cover and is sleeved on the outside of the heat dissipation inner tube and located inside the waste heat recovery tank. The exhaust plate is detachably connected to the heat dissipation inner tube and is located on the top of the heat dissipation inner tube, and is provided with multiple exhaust slots. The hanging column is integrally formed with the second spiral blade and the exhaust plate respectively and is located inside the heat dissipation inner tube. The storage component is located on one side of the waste heat recovery tank.

[0008] The storage component includes a gas tank and an extraction component. The gas tank is located on one side of the waste heat recovery tank and has an insulation layer on its outer wall. The extraction component is located on the side of the waste heat recovery tank near the gas tank.

[0009] The extraction component includes an exhaust fan and a connecting pipe. The exhaust fan is connected to both the connecting pipe and the hot air output pipe. The connecting pipe is connected to both the outlet side of the exhaust fan and the inlet side of the gas tank.

[0010] Both the waste heat recovery tank and the gas tank are equipped with safety valves.

[0011] The auxiliary component also includes a wire mesh, which is fixed to the top of the exhaust plate.

[0012] This utility model discloses a float glass tin bath waste gas adsorption purification and recovery device. During use, heated waste gas is input into the heat dissipation inner tube through a waste gas input pipe. Further, cold air is input into the jacket cavity through a cold air input pipe. The cold air contacts the high-temperature outer surface of the heat dissipation inner tube, achieving temperature rise. Finally, the hot air is extracted and stored through a hot air output pipe and storage components, and then discharged for reuse, achieving heat energy recovery. Simultaneously, the adsorption packing balls inside the heat dissipation inner tube can directly adsorb and purify the waste gas before discharge. Furthermore, the structure of the first spiral plate, the hanging column, and the second spiral plate reduces the waste gas discharge speed and the cold air flow speed, extending the contact time between the cold air and the outer wall of the heat dissipation inner tube per unit time, resulting in faster cold air temperature rise. This solves the problem of existing waste gas recovery devices where the airflow channel inside the heat dissipation inner tube is a straight structure, causing the waste gas to flow rapidly, greatly increasing the heat exchange time with the cold air, resulting in slow temperature rise and inconvenience.

Detailed Implementation

[0019] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] Example 1:

[0021] like Figures 1 to 3 As shown, where Figure 1 This is a schematic diagram of the overall structure of a float glass tin bath exhaust gas adsorption, purification, and recovery device. Figure 2 This is a schematic diagram of the structure of the first helical plate 106. Figure 3 This is a top view of the second spiral blade 109. This utility model provides a float glass tin bath waste gas adsorption, purification, and recovery device: it includes a heat dissipation inner tube 101 and auxiliary components. The auxiliary components include a waste heat recovery tank 102, a waste gas inlet pipe 103, a cold air inlet pipe 104, a hot air outlet pipe 105, a first spiral blade 106, an exhaust plate 107, a hanging column 108, a second spiral blade 109, and a storage component. The storage component includes a gas tank 110 and an extraction component, which includes an exhaust fan 111 and a connecting pipe 112. The aforementioned solution solves the problem that in existing waste gas recovery devices, the airflow channel inside the heat dissipation inner tube 101 is a straight structure, resulting in rapid waste gas flow and significantly increasing the time for heat exchange with cold air, leading to a prolonged cold air temperature rise time and slow heating, making it inconvenient to use. It is understood that the aforementioned solution facilitates rapid heating of the cold air.

[0022] In this embodiment, the heat dissipation inner tube 101 is provided with a plurality of adsorption packing balls (not shown in the figure). The adsorption packing balls are directly used for waste gas adsorption and purification treatment and are arranged in the gap between the heat dissipation inner tube 101 and the second spiral blade 109. The outer diameter of the second spiral blade 109 is smaller than the inner diameter of the heat dissipation inner tube 101. The heat dissipation inner tube 101 is cylindrical and its bottom is welded to the bottom of the waste heat recovery tank 102. A discharge valve is installed at the bottom of the waste heat recovery tank 102 and is connected to the heat dissipation inner tube 101 for subsequent internal cleaning of the heat dissipation inner tube 101.

[0023] The bottom of the heat dissipation inner tube 101 is welded to the inner bottom of the waste heat recovery tank 102 to form a jacketed cavity structure, and its top is slidably connected to the sealing cover 114 of the waste heat recovery tank 102. The exhaust gas inlet pipe 103 is slidably connected to the waste heat recovery tank 102 and threadedly connected to the air inlet of the heat dissipation inner tube 101. The cold air inlet pipe 104 is welded to the bottom side of the waste heat recovery tank 102 and communicates with the jacketed cavity formed by the waste heat recovery tank 102 and the heat dissipation inner tube 101. The hot air outlet pipe 105 is disposed in the waste heat recovery tank 102. 02 The top side is connected to the storage component. The first spiral blade 106 is detachably connected to the sealing cover 114 and sleeved on the outside of the heat dissipation inner tube 101 and located inside the waste heat recovery tank 102. The exhaust plate 107 is detachably connected to the heat dissipation inner tube 101 and located at the top of the heat dissipation inner tube 101, and is provided with multiple exhaust slots. The hanging column 108 is integrally formed with the second spiral blade 109 and the exhaust plate 107 respectively and is located inside the heat dissipation inner tube 101. The storage component is located on one side of the waste heat recovery tank 102. The sealing cover 114 is fixed by bolts. A high-temperature resistant sealing ring is provided in the inner cavity where it contacts the heat dissipation inner tube 101 for contact sealing to prevent exhaust gas leakage. An installation groove is provided on the exhaust gas inlet pipe 103, and a high-temperature resistant sealing ring is fitted inside the installation groove for sealing the contact point between the exhaust gas inlet pipe 103 and the waste heat recovery tank 102. The externally threaded end on the exhaust gas inlet pipe 103's outlet side is directly connected to the threaded air inlet on the heat dissipation inner tube 101. The cold air inlet pipe 104 is used for cold air input. The air output pipe 105 is used for hot air output. Two connecting posts of different lengths are symmetrically arranged on the first spiral blade 106. Multiple threaded holes are provided on the top of the connecting posts to facilitate tightening and fixing to the sealing cover 114 with bolts. The outer diameter of the first spiral blade 106 is smaller than the outer diameter of the waste heat recovery tank 102. Multiple exhaust grooves are provided on the exhaust plate 107 and fixed with bolts. The hanging column 108 is integrally arranged at its bottom. The second spiral blade 109 is integrally arranged on the hanging column 108. The storage component is used for hot air storage.

[0024] Secondly, the gas tank 110 is located on one side of the waste heat recovery tank 102, and an insulation layer is provided on its outer wall; the extraction component is located on the side of the waste heat recovery tank 102 near the gas tank 110. The gas tank 110 is used for hot air storage, and the extraction component is used for hot air extraction.

[0025] Then, the exhaust fan 111 is connected to the connecting pipe 112 and the hot air output pipe 105 respectively; the connecting pipe 112 is connected to the outlet side of the exhaust fan 111 and the inlet side of the gas tank 110 respectively. The flanges on both sides of the exhaust fan 111 are connected to the flanges on the connecting pipe 112 and the hot air output pipe 105 respectively by screws and nuts. When working, the exhaust fan 111 is activated, and at the same time, the I-shaped electric valve on the connecting pipe 112 is activated and opened. The I-shaped electric valve on the cold air input pipe 104 is closed after a certain amount of cold air is input, and is in the closed state when the electric valve on the connecting pipe 112 is opened. Then, the exhaust fan 111 is activated to extract hot air and store it in the gas tank 110. The gas tank 110 is equipped with a discharge valve, which is opened to discharge the hot air for use.

[0026] Finally, both the waste heat recovery tank 102 and the gas tank 110 are equipped with safety valves 113. The function of the safety valves 113 is to automatically release pressure when the internal pressure of the waste heat recovery tank 102 and the gas tank 110 is too high.

[0027] In addressing the problem of existing waste gas recovery devices where the airflow channel inside the heat dissipation inner tube 101 is linear, resulting in rapid waste gas flow and significantly increased heat exchange time with cold air, leading to slow temperature rise and inconvenience, this invention solves the problem of heated waste gas entering the heat dissipation inner tube 101 via the waste gas inlet pipe 103. The waste gas then moves upwards, and simultaneously, under the action of the adsorption packing balls inside the heat dissipation inner tube 101, it undergoes adsorption and purification treatment before discharge. Furthermore, cold air enters the jacket cavity via the cold air inlet pipe 104 and moves upwards, contacting the high-temperature outer surface of the heat dissipation inner tube 101 to achieve temperature rise. Finally, the temperature rises through the... With the hot air output pipe 105 and the exhaust fan 111 working together, the hot air can be extracted and stored in the gas tank 110, and then discharged for use, realizing heat energy recovery and utilization. At the same time, through the structure of the first spiral blade 106, the hanging column 108 and the second spiral blade 109, the exhaust gas discharge speed and the cold air flow speed can be reduced respectively, which helps to extend the contact time between the cold air and the outer wall of the heat dissipation inner pipe 101 per unit time, so that the cold air heats up faster. This solves the problem that the air flow channel inside the heat dissipation inner pipe 101 of the existing exhaust gas recovery and utilization device is a straight structure, which makes the exhaust gas flow in a fast state, greatly increasing the heat exchange time with the cold air, resulting in a long time for the cold air temperature to rise, slow heating and inconvenience.

Based on the first embodiment, this utility model provides a float glass tin bath exhaust gas adsorption purification treatment and recovery device. The auxiliary components also include a wire mesh 201, which is fixed to the top of the exhaust plate 107.

[0030] In this embodiment, the wire mesh 201 is fixed by bolts. After installation, its function is to prevent external impurities from falling into the heat dissipation inner tube 101. At the same time, its mesh holes will enable ventilation to facilitate the discharge of exhaust gas. The surface of the wire mesh 201 is provided with a 0.5mm heat-resistant coating.
