Description

Technical Field

[0001] This utility model belongs to the field of aluminum solid hazardous waste treatment, specifically relating to an aluminum solid hazardous waste treatment waste gas spraying device. Background Technology

[0002] Aluminum and aluminum alloys are among the most widely used and economical materials available today. Aluminum alloys are lightweight yet strong, making them structural materials for manufacturing aircraft, rockets, and automobiles.

[0003] When smelting aluminum frames, coal needs to be added to the smelting furnace to burn the aluminum ore, resulting in a large amount of particulate impurities in the waste gas produced during the smelting process. If the waste gas containing particles is directly introduced into the adsorption tower, it will easily cause the filter plate or adsorber to become clogged, requiring frequent cleaning and replacement of the filter plate or adsorber, which is too troublesome and delays the waste gas treatment progress. Summary of the Invention

[0004] The purpose of this utility model is to provide a waste gas spraying device for treating aluminum solid hazardous waste, which solves the problem that the waste gas flow is too concentrated in the existing waste gas spraying devices for treating aluminum solid hazardous waste, resulting in insufficient waste gas treatment and delaying the waste gas treatment progress.

[0005] To achieve the above objectives, this utility model provides a waste gas spraying device for treating aluminum solid hazardous waste, including a tank. A partition plate is fixedly installed at the lower end of the tank. An exhaust pipe is rotatably installed in the middle of the partition plate. An intake pipe is rotatably installed at the bottom of the exhaust pipe. The intake pipe is fixedly installed through the outer wall of the tank. A driving mechanism is provided at the lower end of the exhaust pipe. A disc is fixedly installed above the exhaust pipe via a support frame. A connecting shaft is provided above the disc. The top of the connecting shaft is fixedly connected to the tank. Multiple baffles are fixedly installed at the lower end of the connecting shaft. Multiple through holes are provided on the baffles. A second baffle is fixedly installed at the upper end of the connecting shaft. Spraying mechanisms are provided above the second baffle and at its edge, and above the first baffle and at its edge.

[0006] The principle of this utility model is as follows: In use, exhaust gas is introduced from the inlet pipe to the outlet pipe. As the drive mechanism drives the outlet pipe to rotate, the disc blocks the exhaust gas flowing out from the top of the outlet pipe, allowing the exhaust gas to flow out quickly and fully from the outside of the disc. As the exhaust gas continues to rise, it will contact the first baffle. Some of the exhaust gas will pass through the through hole of the lower baffle and contact the upper baffle. The remaining exhaust gas will continue to flow along the slope of the first baffle to the edge of the first baffle until it is acted upon by the spraying mechanism. The exhaust gas that rises through the through hole will repeat the above operation to continue to be diverted and spray the part of the exhaust gas flowing to the inner wall of the tank. Subsequently, the exhaust gas that is still rising will be blocked by the second baffle and flow to its edge and be cleaned and purified by the spraying mechanism. Finally, the cleaned exhaust gas will be discharged for subsequent treatment.

[0007] The beneficial effects of this utility model are as follows: by using a pair of baffles to divert the exhaust gas, a single spraying mechanism will not simultaneously remove dust and impurities from a large amount of exhaust gas, thus preventing insufficient treatment. The arrangement of multiple baffles enables the dispersed operation of the exhaust gas, ensuring the efficiency of the spraying mechanism and achieving sufficient treatment of the exhaust gas.

[0008] The rotation of the exhaust pipe provides centrifugal power for the exhaust gas flowing out of the pipe, allowing the exhaust gas to be dispersed before it rises and contacts the baffle, ensuring that the through hole can perform sufficient separation of the exhaust gas.

[0009] Furthermore, the drive mechanism includes a first gear, which is fixedly mounted on the air outlet pipe. A second gear meshes with the side of the first gear, and a drive shaft is fixedly mounted on the second gear. The top of the drive shaft is rotatably connected to the partition plate, and a drive motor is fixedly mounted on the bottom of the drive shaft. The drive motor is fixed to the tank body via a bracket. Through the transmission between the gears, the operation of the drive motor provides power for the rotation of the air outlet pipe.

[0010] Furthermore, the spraying mechanism includes an annular water outlet pipe, on which multiple atomizing nozzles are fixedly installed. These atomizing nozzles face the inner wall of the tank. An inlet pipe is also installed on the water outlet pipe, penetrating the tank. Through the multiple atomizing nozzles, sufficient water is sprayed between the baffle and the inner wall of the tank, ensuring adequate contact between the water mist and the exhaust gas.

[0011] Furthermore, the connecting shaft is a hollow tube with an open bottom. Several spaced-apart water inlets are provided on the side of the connecting shaft, above both the first and second baffles. These inlets collect water falling above the baffles, preventing excessive water accumulation from increasing the weight of the baffles and causing damage at the connection between the baffles and the connecting shaft.

[0012] Furthermore, both the first and second baffles are umbrella-shaped with their openings facing upwards. Through the umbrella-shaped structure of the baffles, water falling on the baffles can converge towards the center and flow into the water inlet, making it easier to collect the water remaining on the baffles.

[0013] Furthermore, the through holes on two adjacent baffles are staggered. These through holes allow water falling onto the baffles to drain through them, preventing water from accumulating on the baffles. Simultaneously, the staggered arrangement of the through holes prevents the rising exhaust gas from directly passing through baffle one and falling onto baffle two, thus facilitating the diversion of the exhaust gas.

[0014] Furthermore, the edge of the disc is inclined downwards, and a gap is left between the bottom of the connecting shaft and the disc. This inclined arrangement of the disc allows water flowing into the connecting shaft to fall downwards along the shaft onto the partition plate, so that it can be treated together with the wastewater.

[0015] Furthermore, an inlet and outlet are provided on the lower side of the tank, above the partition plate, and sealed doors are installed on the inlet and outlet. These sealed doors facilitate the treatment of wastewater falling onto the partition plate. An exhaust pipe is installed on the top of the tank. This exhaust pipe is used to discharge the treated waste gas. Attached Figure Description

Detailed Implementation

[0022] like Figure 1 , Figure 2, Figure 3 , Figure 4 As shown, this embodiment provides an aluminum solid hazardous waste treatment exhaust gas spraying device, including a tank 1. A partition plate 2 is fixedly installed at the lower end of the tank 1. An exhaust pipe 4 is rotatably installed in the middle of the partition plate 2, and an intake pipe 3 is rotatably installed at the bottom of the exhaust pipe 4. The intake pipe 3 is fixedly installed through the outer wall of the tank 1. A drive mechanism 20 is provided at the lower end of the exhaust pipe 4. The drive mechanism 20 includes a gear 14, which is fixedly installed on the exhaust pipe 4. A gear 15 meshes with the side of the gear 14. A drive shaft 16 is fixedly installed on the gear 15. The top of the drive shaft 16 is rotatably connected to the partition plate 2, and a drive motor 17 is fixedly installed at the bottom of the drive shaft 16. The drive motor 17 is fixed to the tank 1 via a bracket. Through the transmission between the gears, the drive motor 17 provides power for the rotation of the exhaust pipe 4. An inlet and outlet are provided at the lower side of the tank 1, above the partition plate 2, and sealing doors 19 are installed on the inlet and outlet. The sealed door 19 facilitates the treatment of wastewater that falls onto the partition plate 2. An exhaust pipe 18 is installed on the top of the tank 1. The treated exhaust gas is discharged through the exhaust pipe 18.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a disc 5 is fixedly installed above the exhaust pipe 4 via a support frame. A connecting shaft 6 is located above the disc 5, and the top of the connecting shaft 6 is fixedly connected to the tank body 1. Multiple baffles 7 are fixedly installed at the lower end of the connecting shaft 6, and multiple through holes 8 are provided on the baffles 7. A second baffle 9 is fixedly installed at the upper end of the connecting shaft 6. Spraying mechanisms 21 are provided above the second baffle 9 and at its edge, and above the first baffle 7 and at its edge. The spraying mechanism 21 includes an annular water outlet pipe 10, on which multiple atomizing nozzles 11 are fixedly installed. The atomizing nozzles 11 are positioned facing the inner wall of the tank body 1. A water inlet pipe 12 is installed on the water outlet pipe 10, and the water inlet pipe 12 penetrates the tank body 1. Through the multiple atomizing nozzles 11, sufficient water is sprayed into the gap between the baffles and the inner wall of the tank body 1, ensuring sufficient contact between the water mist and the exhaust gas.

[0024] like Figure 3 , Figure 4As shown, the connecting shaft 6 is a hollow tube with an open bottom. Several spaced-apart water inlets 13 are provided on the side of the connecting shaft 6, above both the first baffle 7 and the second baffle 9. These inlets 13 collect water falling above the baffles, preventing excessive water accumulation from increasing the baffle's weight and causing damage at the connection between the baffle and the connecting shaft 6. Both the first baffle 7 and the second baffle 9 are umbrella-shaped with upward openings. This umbrella-like structure allows water falling on the baffles to converge towards the center and flow into the water inlets 13, facilitating the collection of residual water. The through holes 8 on adjacent first baffles 7 are staggered. These through holes 8 allow water falling on the baffles to fall through and drain, preventing water deposition. Simultaneously, the staggered arrangement of the through holes 8 prevents the rising exhaust gas from directly passing through the first baffle 7 and falling onto the second baffle 9, thus aiding in exhaust gas diversion. The edge of the disc 5 is inclined downwards, and a gap is left between the bottom of the connecting shaft 6 and the disc 5. The inclined arrangement of the disc 5 allows water flowing into the connecting shaft 6 to fall downwards onto the partition plate 2, so that it can be treated together with the wastewater.

[0025] The specific implementation process of this utility model is as follows: In use, the exhaust gas is introduced from the inlet pipe 3 to the outlet pipe 4. As the drive mechanism 20 drives the outlet pipe 4 to rotate, the disc 5 blocks the exhaust gas flowing out from the top of the outlet pipe 4, allowing the exhaust gas to flow out quickly and fully from the outside of the disc 5. As the exhaust gas continues to rise, it will contact the baffle 7. Some of the exhaust gas will pass through the through hole 8 of the lower baffle 7 and contact the upper baffle 9. The remaining exhaust gas will continue to flow along the slope of the baffle 7 to the edge of the baffle 7 until it is acted upon by the spraying mechanism 21. The exhaust gas that rises through the through hole 8 will repeat the above operation to continue to divert and spray the part of the exhaust gas that flows to the inner wall of the tank 1. Subsequently, the exhaust gas that is still rising will be blocked by the baffle 9 and flow to its edge and be cleaned by the spraying mechanism 21. Finally, the cleaned exhaust gas will be discharged from the exhaust pipe 18 for subsequent treatment.

[0026] This solution uses baffle 7 to divert the exhaust gas, preventing a single spraying mechanism 21 from simultaneously removing dust and impurities from a large amount of exhaust gas, thus avoiding insufficient treatment. The multiple baffles 7 disperse the exhaust gas, ensuring the efficiency of the spraying mechanism 21 and achieving sufficient treatment of the exhaust gas. The rotation of the exhaust pipe 4 provides centrifugal power for the exhaust gas flowing out of the exhaust pipe 4, allowing the exhaust gas to be dispersed before it rises and contacts the baffle 7, ensuring that the through hole 8 can perform sufficient separation of the exhaust gas.
