Description

Technical Field

[0001] This utility model belongs to the field of waste gas treatment technology, specifically referring to a waste gas treatment device for lead smelting. Background Technology

[0002] The lead smelting process generates a large amount of waste gas containing heavy metals and acidic gases. This waste gas not only causes serious environmental pollution but also poses a threat to human health. Therefore, effective treatment of lead smelting waste gas is a crucial aspect of environmental protection and industrial production.

[0003] Traditional lead smelting waste gas treatment devices have low filtration efficiency. Existing equipment mostly uses gravity separation to treat large particles of waste residue, which often makes it difficult to achieve efficient separation. As a result, waste residue tends to accumulate in the filtration device, affecting the continuous and stable operation of the equipment. Moreover, high-temperature waste gas needs to be cooled before entering subsequent treatment equipment or being discharged. Traditionally, straight-tube coolers are used, which have low heat exchange efficiency and limited cooling effect, making it difficult to quickly and effectively reduce the temperature of the waste gas. Utility Model Content

[0004] To address the aforementioned problems of low filtration efficiency in traditional lead smelting waste gas treatment devices and low heat exchange efficiency in traditional cooling equipment, this utility model provides a waste gas treatment device for lead smelting.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: A waste gas treatment device for lead smelting includes a base plate. A waste residue filter box is arranged on the upper left side of the base plate. A waste residue collection box installed on the base plate is connected to the bottom of the waste residue filter box. An air inlet pipe with a valve is connected to the left side of the waste residue filter box. An air outlet pipe with a valve is connected to the right side of the waste residue filter box. A cooling box is arranged on the upper right side of the base plate. A cooling pipe is arranged inside the cooling box. The air outlet pipe is connected to the inlet end of the cooling pipe. An air outlet pipe with a valve is connected to the outlet end of the cooling pipe. A water inlet pipe is connected to the bottom right side of the cooling box. A water outlet pipe is connected to the top left side of the cooling box. The water outlet pipe is connected to an external water pump. An inclined baffle is installed inside the waste residue filter box. A collection component is installed on the waste residue filter box.

[0006] As a preferred technical solution of this utility model, the collection component is located on the lower side of the baffle. The collection component includes a motor, which is fixedly installed on the outer wall of the waste residue filter box. The output end of the motor rotates through the waste residue filter box and is connected to a rotating shaft. The end of the rotating shaft away from the motor is rotatably connected to the inner wall of the waste residue filter box. Rectangular fan blades are evenly distributed on the rotating shaft, and the edges of the fan blades maintain a small gap with the inner wall of the waste residue filter box.

[0007] As a preferred embodiment of this utility model, the waste residue filter box has a rectangular cross-section and an open bottom. The bottom of the waste residue filter box is connected to a trapezoidal hopper with a trapezoidal cross-section and open top and bottom. The bottom of the trapezoidal hopper is connected to a rectangular pipe, and the bottom of the rectangular pipe is connected to the waste residue collection box.

[0008] As a preferred embodiment of this utility model, the baffle is inclined from the upper right side to the lower left side of the waste residue filter box, with an inclination angle between 30° and 45°. The right end of the baffle is horizontally connected to the inner wall of the waste residue filter box, and the left side of the baffle is 10-20cm away from the inner wall of the waste residue filter box. The air inlet pipe is located on the upper side of the baffle, and the air outlet pipe is located on the lower side of the baffle.

[0009] As a preferred embodiment of this utility model, a first support column is evenly arranged between the bottom of the waste residue filter box and the bottom plate, and a second support column is evenly arranged between the cooling box and the bottom plate.

[0010] As a preferred embodiment of this utility model, the first air outlet pipe and the second air outlet pipe are located on the upper left side and the lower right side of the cooling box, respectively.

[0011] As a preferred technical solution of this utility model, the cooling tube adopts a spiral coil structure and the material of the cooling tube is 316L stainless steel.

[0012] Compared with the prior art, the present invention achieves the following beneficial effects by adopting the above structure:

[0013] 1. Through the coordinated design of baffles and collection components, large particulate waste residue in lead smelting exhaust gas can be efficiently separated and collected. The inclined baffles allow large particulate waste residue to settle naturally under gravity. At the same time, the motor drives the rotating shaft and rectangular fan blades to rotate and collect the waste residue falling onto the fan blades into the waste residue collection box in a timely manner, preventing the waste residue from accumulating in the waste residue filter box and ensuring the continuous and stable operation of the waste residue filter box;

[0014] 2. The coordinated design of the cooling pipes, inlet pipe, outlet pipe, and cooling box effectively reduces the temperature of the exhaust gas. The cooling pipes adopt a spiral coil structure, which increases the contact area between the exhaust gas and the cooling water, improving heat exchange efficiency. The cooling water is injected into the cooling box through the inlet pipe, absorbs heat from the exhaust gas, and is discharged through the outlet pipe, ensuring a significant reduction in exhaust gas temperature and preventing high-temperature exhaust gas from damaging subsequent equipment or the environment.

The utility model will be further described in detail below with reference to the accompanying drawings.

[0022] like Figure 1-4As shown, this utility model provides a waste gas treatment device for lead smelting, including a base plate 1. A waste residue filter box 2 is arranged on the upper left side of the base plate 1. The bottom of the waste residue filter box 2 is connected to a waste residue collection box 3 installed on the base plate 1. An air inlet pipe 4 with a valve is connected to the left side of the waste residue filter box 2, and an air outlet pipe 5 with a valve is connected to the right side of the waste residue filter box 2. A cooling box 6 is arranged on the upper right side of the base plate 1. Support columns 17 are evenly arranged between the bottom of the waste residue filter box 2 and the base plate 1, and support columns 28 are evenly arranged between the cooling box 6 and the base plate 1 to ensure the overall structural stability of the device. A cooling pipe 7 is arranged inside the cooling box 6. The cooling pipe 7 adopts a spiral coil structure, which increases the contact area between the waste gas and the cooling water and improves the cooling efficiency. The cooling pipe 7 is made of stainless steel 3. The 16L coolant has good corrosion resistance and high temperature resistance. The exhaust pipe 5 is connected to the inlet end of the cooling pipe 7, and the outlet end of the cooling pipe 7 is connected to the exhaust pipe 19 with a valve. The bottom right side of the cooling box 6 is connected to the water inlet pipe 8, and the top left side of the cooling box 6 is connected to the water outlet pipe 9, which is connected to an external water pump. The exhaust pipe 5 and the exhaust pipe 19 are located on the upper left side and the lower right side of the cooling box 6, respectively, to ensure a reasonable flow direction of the exhaust gas and improve the treatment efficiency. Cooling water is injected into the cooling box 6 through the water inlet pipe 8. The cooling water absorbs the high temperature of the exhaust gas in the cooling pipe 7 and is discharged through the water outlet pipe 9, effectively reducing the temperature of the exhaust gas. The waste residue filter box 2 is equipped with an inclined baffle 10 for separating large particles of waste residue. The waste residue filter box 2 is equipped with a collection component 11.

[0023] like Figure 1-4 As shown, the collection component 11 is located below the baffle 10. The collection component 11 includes a motor 12, which is fixedly installed on the outer wall of the waste residue filter box 2. The output end of the motor 12 rotates through the waste residue filter box 2 and is connected to a rotating shaft 13. The end of the rotating shaft 13 away from the motor 12 is rotatably connected to the inner wall of the waste residue filter box 2. Rectangular fan blades 14 are evenly distributed on the rotating shaft 13. The edges of the fan blades 14 maintain a small gap with the inner wall of the waste residue filter box 2. When the motor 12 is started, the motor 12 drives the rotating shaft 13 to rotate, and the rectangular fan blades 14 on the rotating shaft 13 rotate accordingly. This can rotate the waste residue that falls on the fan blades 14 into the waste residue collection box 3, effectively preventing the waste residue from accumulating in the waste residue filter box 2.

[0024] like Figure 1-4 As shown, the waste residue filter box 2 has a rectangular cross-section and an open bottom. The bottom of the waste residue filter box 2 is connected to a trapezoidal hopper 15 with a trapezoidal cross-section and an open top and bottom. The bottom of the trapezoidal hopper 15 is connected to a rectangular pipe 16. The bottom of the rectangular pipe 16 is connected to the waste residue collection box 3. The settled waste residue enters the trapezoidal hopper 15 through the bottom opening and then falls into the waste residue collection box 3 through the rectangular pipe 16 for centralized treatment.

[0025] like Figure 3-4As shown, the baffle 10 is inclined from the upper right side to the lower left side of the waste residue filter box 2, with an inclination angle between 30° and 45°. This angle range is designed to balance the waste gas flow rate and the waste residue settling efficiency, effectively slowing down the waste gas flow rate and allowing large particles of waste residue to settle under gravity. The right end of the baffle 10 is horizontally connected to the inner wall of the waste residue filter box 2, and the left side of the baffle 10 is 10-20cm away from the inner wall of the waste residue filter box 2, forming an airflow channel. This allows the waste gas to enter the outlet pipe 5 through the bottom of the baffle 10. The inlet pipe 4 is located on the upper side of the baffle 10, and the outlet pipe 5 is located on the lower side of the baffle 10.

[0026] In practical use, first turn on the external water pump to let the cooling water flow in from the inlet pipe 8 at the bottom right side of the cooling box 6. After heat exchange through the outer wall of the cooling pipe 7, it is discharged from the outlet pipe 9 at the top left side. Then, open the valve of the air inlet pipe 4 to let the lead smelting waste gas enter the waste residue filter box 2. Under the action of the inclined baffle 10, the large particles of waste residue in the waste gas settle to the bottom of the box due to gravity, and fall into the waste residue collection box 3 through the trapezoidal hopper 15 and the rectangular pipe 16. When a lot of waste residue accumulates inside the waste residue filter box 2, start the motor 12 to drive the rotating shaft 13 and the fan blade 14 to rotate, scraping the waste residue into the collection box to avoid the accumulation of waste residue from affecting the filtration effect.

[0027] After preliminary filtration, the exhaust gas enters the spiral coil cooling tube 7 from the exhaust pipe 5 at the upper left side of the cooling box 6, flows along the coil and exchanges heat with the cooling water flowing in the opposite direction, resulting in a significant temperature reduction; the cooled exhaust gas is discharged from the exhaust pipe 19 at the lower right side of the cooling box 6, completing the treatment process.

[0028] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
