Description

Technical Field

[0001] This utility model relates to the field of aluminum ash waste gas recovery technology, and in particular to a device for recovering and utilizing waste heat from aluminum ash waste gas. Background Technology

[0002] Aluminum ash exhaust gas mainly originates from the treatment and utilization process of aluminum ash. It contains harmful substances such as particulate matter, fluorides, and ammonia, which pose potential hazards to the environment and human health. When aluminum ash exhaust gas is emitted, it still contains a certain amount of heat, which needs to be recovered and utilized through waste heat recovery and utilization devices.

[0003] A waste heat recovery and utilization device with application number CN202323144483.6 cools the hot gas inside the tank through a heat exchange component and then discharges it through a flue gas exhaust pipe, reducing the heat dissipated into the atmosphere and improving resource utilization. The entire tank structure can reduce the ineffective waste of thermal energy and reduce environmental pollution. However, the filtration structure inside the tank is relatively lacking. When the waste gas is passed into the tank for recovery and utilization and then discharged, the waste gas still contains certain impurities and harmful substances, which will cause environmental pollution. Utility Model Content

[0004] This utility model discloses a waste heat recovery and utilization device for aluminum ash exhaust gas, which aims to solve the technical problem that the filtration structure inside the tank is relatively lacking, and the exhaust gas still contains certain impurities and harmful substances when it is passed into the tank for recovery and utilization, which will cause environmental pollution.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A waste heat recovery and utilization device for aluminum ash exhaust gas includes a recovery box. A filter frame is slidably connected to the front end of the recovery box. A fixing plate is snapped onto the front end of the filter frame. Filter plates are slidably connected to the upper and lower ends of the filter frame. An activated carbon plate is slidably connected to the middle of the filter frame. Locking blocks are fixedly installed on the left and right sides of the front end of the filter frame. The fixing plate has locking grooves on the left and right sides. A limiting plate is slidably connected to the inside of the locking grooves near the central axis. A limiting groove is opened at the front end of the locking blocks. A stabilizing plate is fixedly installed at the front end of the recovery box below the fixing plate. A locking block is slidably connected to the inside of the stabilizing plate. A locking groove is opened at the lower end of the fixing plate. A first spring is provided between the locking block and the stabilizing plate.

[0007] By setting up a filter plate and activated carbon plate together, the waste gas after recycling is prevented from containing a large number of impurities and harmful substances, thus avoiding environmental pollution and improving the safety of waste gas emissions. At the same time, the combination of the clip and locking block facilitates the disassembly and installation of the filter plate and activated carbon plate, as well as the cleaning and replacement of the filter plate and activated carbon plate, while ensuring the stability of the filter frame during use.

[0008] In a preferred embodiment, a top cover is fixedly installed on the upper end of the recycling box, a heating box is fixedly installed on the right side of the recycling box, a heat insulation ring is sleeved on the middle of the outer side of the recycling box, a heat conducting ring is fixedly installed inside the heat insulation ring, a first heating wire is fixedly installed at the upper and lower ends of the outer side of the heat conducting ring, a heating plate is fixedly installed inside the heating box, and a second heating wire is fixedly installed in the middle of the left and right sides of the heating plate.

[0009] By setting up a heat-conducting ring and a heat-insulating ring, the heat from the outside of the recovery box is transferred to the heat-conducting ring. The heat-insulating ring prevents the heat-conducting ring from contacting the air, keeping the heat on the heat-conducting ring. At the same time, the first heating wire and the second heating wire work together to facilitate the heating of the cold water entering the heating box, thus realizing the recovery and utilization of waste heat.

[0010] In a preferred embodiment, a liquid inlet pipe is fixedly installed at the rear end of the heating box, a locking ring is sleeved at the rear end of the liquid inlet pipe, a filter cylinder is slidably connected inside the rear end of the liquid inlet pipe, limit blocks are fixedly installed at the rear sides of the upper and lower ends of the liquid inlet pipe, a movable groove is opened at the front end of the inside of the locking ring, a push plate is slidably connected inside the rear end of the locking ring, and a second spring is provided between the push plate and the locking ring.

[0011] By setting a locking ring and a push plate to work together, the locking ring can be easily locked, ensuring the stability of the locking ring when locked and improving the stability of the filter cartridge during use. At the same time, the filter cartridge filters cold water to prevent impurities from adsorbing onto the heating plate and affecting the heating efficiency of the heating plate.

[0012] As can be seen from the above, the aluminum ash waste gas waste heat recovery and utilization device provided by this utility model, by setting a filter plate and an activated carbon plate together, avoids the waste gas after recovery from containing a large number of impurities and harmful substances, thereby causing environmental pollution and improving the safety of waste gas emissions. At the same time, the combination of the locking block and the clamping block facilitates the disassembly and installation of the filter plate and the activated carbon plate, facilitates the cleaning and replacement of the filter plate and the activated carbon plate, and ensures the stability of the filter frame during use.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] The aluminum ash waste gas waste heat recovery and utilization device disclosed in this utility model is mainly used in scenarios where the filtration structure inside the tank is relatively lacking, and the waste gas still contains certain impurities and harmful substances when it is passed into the tank for recovery and utilization and discharge, which will cause environmental pollution.

[0024] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 A waste heat recovery and utilization device for aluminum ash exhaust gas includes a recovery box 1. A filter frame 2 is slidably connected to the front end of the recovery box 1. A fixing plate 3 is snapped onto the front end of the filter frame 2. Filter plates 4 are slidably connected to the upper and lower ends of the filter frame 2. An activated carbon plate 5 is slidably connected to the middle of the filter frame 2. A locking block 6 is fixedly installed on the left and right sides of the front end of the filter frame 2. The fixing plate 3 has a locking groove 7 on the left and right sides. A limiting plate 8 is slidably connected to the inside of the locking groove 7 near the central axis. A limiting groove 9 is opened at the front end of the locking block 6. A stabilizing plate 10 is fixedly installed at the lower end of the fixing plate 3 at the front end of the recovery box 1. A locking block 11 is slidably connected to the inside of the stabilizing plate 10. A locking groove 12 is opened at the lower end of the fixing plate 3. A first spring 13 is provided between the locking block 11 and the stabilizing plate 10.

[0025] In this embodiment: When aluminum ash exhaust gas is introduced into the lower end of the recycling box 1, the exhaust gas will first come into contact with the filter plate 4 on the filter frame 2. The filter plate 4 intercepts and filters the impurities in the aluminum ash exhaust gas. At the same time, the activated carbon plate 5 intercepts the harmful substances in the aluminum ash exhaust gas, preventing the recycled exhaust gas from containing a large number of impurities and harmful substances, thus avoiding environmental pollution and improving the safety of exhaust gas emissions. When the filter plate 4 and activated carbon plate 5 have been used for a long time, they need to be replaced and cleaned. Pull the locking block 11 in the stabilizing plate 10 to disengage the locking block 11 from the locking groove 12 on the fixing plate 3, and compress the first spring 13 to release the lock on the fixing plate 3. Pull the fixing plate 3 to remove the filter frame 2 from the recycling box 1. Then slide the limiting plate 8 on the fixing plate 3 to disengage the limiting plate 8 from the limiting groove 9 on the locking block 6. Pull the fixing plate 3 to disengage the slot 7 on the fixing plate 3 from the locking block 6, thereby exposing the filter plate 4 and activated carbon plate 5 inside the filter frame 2. This facilitates the cleaning and replacement of the filter plate 4 and activated carbon plate 5, preventing the filter plate 4 from becoming clogged after prolonged use and affecting the filtration efficiency. After cleaning and replacing the filter plate 4 and activated carbon plate 5, reinsert the filter plate 4 and activated carbon plate 5 into the filter frame 2. Then, align the slot 7 on the fixing plate 3 with the locking block 6 and insert it to make the fixing plate 3 fit against the filter frame 2. Then, slide the limiting plate 8 to slide into the limiting groove 9 to lock the fixing plate 3. Then, insert the filter frame 2 into the recycling box 1 and release the locking block 11. The first spring 13 returns to its original position, causing the locking block 11 to engage in the locking groove 12, thereby locking the fixing plate 3 and ensuring the stability of the filter frame 2 during use.

[0026] Reference Figure 1 and Figure 2 A top cover 14 is fixedly installed on the upper end of the recycling box 1. A heating box 15 is fixedly installed on the right side of the recycling box 1. A heat insulation ring 16 is sleeved on the middle of the outer side of the recycling box 1. A heat conduction ring 17 is fixedly installed inside the heat insulation ring 16. A first heating wire 18 is fixedly installed on the upper and lower ends of the outer side of the heat conduction ring 17. A heating plate 19 is fixedly installed inside the heating box 15. A second heating wire 20 is fixedly installed on the middle of the left and right sides of the heating plate 19.

[0027] In this embodiment: When the recycling box 1 is in use, the top cover 14 can prevent rainwater from entering and slow down the rate of exhaust gas discharge, making it easier for the heat of the exhaust gas to be retained inside the recycling box 1. The heat-conducting ring 17 is in close contact with the recycling box 1. When exhaust gas is introduced into the recycling box 1, the hotter exhaust gas will also conduct heat to the recycling box 1, thereby transferring the heat to the heat-conducting ring 17. The heat insulation ring 16 prevents the heat-conducting ring 17 from contacting the air, retaining the heat on the heat-conducting ring 17. Subsequently, the heat-conducting ring 17 conducts heat to the first heating wire 18. The first heating wire 18 transfers heat to the heating plate 19 inside the heating box 15. The heating plate 19 heats the cold water introduced into the heating box 15, realizing the recovery and utilization of waste heat. At the same time, the second heating wire 20 is located inside the recycling box 1 and is in direct contact with the exhaust gas. The heat of the exhaust gas is transferred to the second heating wire 20, and the second heating wire 20 also transfers heat to the heating plate 19, improving the heating efficiency of the heating plate 19.

[0028] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 The heating box 15 has an inlet pipe 21 fixedly installed at the rear end. A locking ring 22 is sleeved at the rear end of the inlet pipe 21. A filter cylinder 23 is slidably connected inside the rear end of the inlet pipe 21. Limiting blocks 24 are fixedly installed on the rear side of the upper and lower ends of the inlet pipe 21. A movable groove 25 is opened at the front end inside the locking ring 22. A push plate 26 is slidably connected inside the rear end of the locking ring 22. A second spring 27 is provided between the push plate 26 and the locking ring 22.

[0029] In this embodiment: Cold water is introduced into the heating box 15 through the inlet pipe 21. The filter cylinder 23 filters the cold water to prevent excessive impurities from being present in the cold water and adhering to the heating plate 19, thus affecting the heating efficiency of the heating plate 19. When the filter cylinder 23 needs to be disassembled and cleaned, the locking ring 22 is pushed forward to press the push plate 26, which compresses the second spring 27 and simultaneously disengages the limiting block 24 from the movable groove 25. Then, the locking ring 22 is rotated and pulled backward to completely disengage the limiting block 24 from the movable groove 25, thus removing it from the cover of the filter cylinder 23. After cleaning and replacing the filter cylinder 23, the filter... The filter cartridge 23 is reinserted into the liquid pipe 21, and the movable groove 25 on the locking ring 22 is aligned with the limiting block 24 and inserted to the bottom. At the same time, the push plate 26 is squeezed and the second spring 27 is compressed. The locking ring 22 is rotated, causing the limiting block 24 to slide in the movable groove 25. When the limiting block 24 slides to the designated position, the locking ring 22 is released, the second spring 27 is reset, and the push plate 26 is squeezed, thereby driving the locking ring 22 to slide backward, so that the limiting block 24 is locked into the movable groove 25, thereby locking the locking ring 22, ensuring the stability of the locking ring 22 when locked, and improving the stability of the filter cartridge 23 during use.

[0030] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
