Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment, and in particular to a device for treating waste gas from secondary lead smelting. Background Art

[0002] At present, most of my country's secondary lead enterprises mainly use traditional smelting processes such as reverberatory furnaces, blast furnaces and cupolas. The grids and lead mud are mixed together, basically without any pretreatment process.

[0003] Patent document CN104451161A discloses a method for low-temperature smelting of recycled lead, which belongs to the technical field of recycled lead preparation. The method provides an alkaline environment by sodium carbonate, uses recycled lead raw material and / or lead ore powder as the lead source, and uses carbon as a reducing agent to perform alkaline smelting at 800-1100°C to produce three products: crude lead or precious lead, smelting slag and flue gas. Most of the precious metals such as gold and silver enter the crude lead or precious lead, and the crude lead produced by smelting sinks to the bottom and is discharged. Sulfur enters the smelting slag in the form of sodium sulfide. After the smelting slag is soaked in water, the filtrate is concentrated and crystallized step by step to obtain sodium carbonate and sodium sulfide products. After the flue gas is dust-removed, the smoke returns to the raw material, and the waste gas is directly discharged after being absorbed by alkaline solution.

[0004] However, during actual use, the inventor discovered that the exhaust gas treatment was incomplete and a new filter element could not be updated during continuous exhaust. Summary of the invention

[0005] The purpose of the present invention is to address the deficiencies of the prior art by regularly converting and updating the adsorption part of the exhaust gas adsorption assembly, thereby solving the technical problems of incomplete exhaust gas treatment and inability to update new filter elements during continuous exhaust.

[0007] During the rotation of the exhaust gas adsorption component, new adsorbent is connected between pipe a and pipe b, and old adsorbent is transferred out from between pipe a and pipe b, thereby completing the regeneration work.

[0008] Preferably, the exhaust gas adsorption component comprises:

[0009] An adsorbent, which is rotatably disposed on the shell and is used to complete the treatment of the exhaust gas;

[0010] The sealing member is provided in two groups and completes the sealing work of the adsorption member on the pipeline a and the pipeline b.

[0011] Preferably, the adsorption member comprises a rotating frame, a plurality of groups of mounting grooves arranged at equal intervals along the circumferential direction of the rotating frame, and a storage bin rotatably arranged in the mounting grooves and having a rubber material structure in the outer circumferential direction;

[0012] Porous solid particles are arranged in the storage bin.

[0013] Preferably, the rotating frame is driven to rotate by a first driving member, and the first driving member includes a driving motor and a driving shaft arranged at the output of the driving motor and connected to the rotating frame.

[0014] Preferably, the storage bin is driven to rotate by a second driving member, which includes a rotating shaft connected to the storage bin and rotatably arranged on a rotating frame, a bevel gear group structure driving the rotating shaft to rotate, and a rack group installed in the outer shell and driving the bevel gear group structure to transmit.

[0015] Preferably, the sealing members are provided in two groups and are symmetrically arranged on both sides of the exhaust gas adsorption assembly, and include a sliding rod elastically arranged on the outer shell and a lifting block arranged outside the sliding rod.

[0016] Preferably, the contact portion between the sliding rod and the exhaust gas adsorption assembly is made of rubber material.

[0017] Preferably, the lifting block is lifted by a cam structure, and the cam structure is driven synchronously with the first driving member.

[0018] Also preferably, the interior of the housing is a low-pressure environment.

[0019] Beneficial effects of the present invention:

[0020] (1) In the present invention, the exhaust gas filtration work output by the pipeline a is completed by setting the exhaust gas adsorption component, and the adsorption part of the exhaust gas adsorption component is regularly converted and updated, thereby improving the overall exhaust gas purification effect and increasing the service life of the equipment;

[0021] (2) In the present invention, a second driving member is provided to drive the storage bin to rotate, so that the exhaust gas output from the pipeline a is adsorbed by the front and back sides of the storage bin respectively, thereby completing the automatic switching of the storage bin and improving the service life and efficiency of the adsorption part.

[0031] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

[0032] Embodiment 1

[0033] like Figures 1 to 6 As shown, a waste gas treatment device for secondary lead smelting includes a pipe a1 connected to an output end of a secondary lead smelting furnace 100, a pipe b2 spaced apart from the pipe a1, and a waste gas adsorption component 3 disposed between the pipe a1 and the pipe b2, wherein the waste gas adsorption component 3 is covered with a shell 4;

[0034] During the rotation of the exhaust gas adsorption component 3 , new adsorbent is connected between the pipe a1 and the pipe b2 , and the old adsorbent is transferred out from between the pipe a1 and the pipe b2 , thus completing the regeneration work.

[0035] In this embodiment, the exhaust gas adsorption component 3 is provided to complete the exhaust gas filtration work output by the pipeline a1, and the adsorption part of the exhaust gas adsorption component 3 is regularly converted and updated to improve the overall exhaust gas purification effect and increase the service life of the equipment.

[0036] Further, if Figures 1 to 6 As shown, the exhaust gas adsorption component 3 includes:

[0037] An adsorbent 31, the adsorbent 31 is rotatably disposed on the housing 4 and is used to complete the treatment of the exhaust gas;

[0038] The sealing member 32 is provided in two groups and completes the sealing work of the adsorption member 31 on the pipeline a1 and the pipeline b2.

[0039] Further, if Figure 3 As shown, the rotating frame 311 is driven to rotate by a first driving member 314 , and the first driving member 314 includes a driving motor 3141 and a driving shaft 3142 which is arranged at the output of the driving motor 3141 and connected to the rotating frame 311 .

[0040] It is worth noting that the drive motor 3141 is pre-set to periodically transmit a certain angle to complete the update work, and a sealing ring is provided at the connection between the drive shaft and the housing.

[0041] Further, if Figure 3 to Figure 4 The adsorption member 31 shown includes a rotating frame 311, a plurality of groups of mounting grooves 312 arranged at equal intervals along the circumference direction of the rotating frame 311, and a storage bin 313 rotatably arranged in the mounting grooves 312 and having a rubber material structure in the outer circumferential direction;

[0042] The storage bin 313 is provided with porous solid particles.

[0043] Further, if Figures 4 to 5 As shown, the storage bin 313 is driven to rotate by a second driving member 315, which includes a rotating shaft 3151 connected to the storage bin 313 and rotatably arranged on the rotating frame 311, a bevel gear group structure 3152 driving the rotating shaft 3151 to rotate, and a rack group 3153 installed in the outer shell 4 and driving the bevel gear group structure 3152 to transmit.

[0044] In this embodiment, a second driving member 315 is provided to drive the storage bin 313 to rotate, so that the exhaust gas output from the pipe a1 is adsorbed on both sides of the storage bin 313, thereby completing the automatic switching of the storage bin 313 and improving the service life and efficiency of the adsorption part.

[0045] In detail, the bevel gear group structure 3152 meshes with the rack group 3153 during the transmission process, and drives the storage bin 313 to rotate through the rotating shaft 3151.

[0046] Further, if Figure 6 to Figure 7As shown, the sealing member 32 is provided in two groups and symmetrically arranged on both sides of the exhaust gas adsorption assembly 3, which includes a sliding rod 321 elastically arranged on the housing 4 and having an inclined structure, a lifting block 322 arranged outside the sliding rod 321, and a sealing ring 323 horizontally sliding on the pipe a1 and the pipe b2;

[0047] The contact portion between the sealing ring 323 and the exhaust gas adsorption component 3 is made of rubber material;

[0048] The lifting block 322 is lifted by the cam 324 structure, and the cam 324 structure is synchronously driven with the first driving member 314. When the sliding rod 321 descends, the inclined surface acts on the sealing ring 323, and the two groups of sealing rings 323 move horizontally toward each other to complete the sealing work of the exhaust gas adsorption component 3.

[0049] In this embodiment, by providing a seal 32 in conjunction with the first drive member 314, on the one hand, the exhaust gas is always in a sealed state in the path from pipe a to pipe b to prevent exhaust gas leakage; on the other hand, power is shared, saving additional power output and reducing production costs.

[0050] It is worth mentioning that every time the driving motor 3141 rotates a certain angle, the speed is adjusted by meshing a plurality of large and small gear sets, so that the cam 324 structure transmits one circle synchronously, and the lifting block 322 is lifted a certain distance under the guidance of the cam 324, so that the clamping force at this time is sufficient for the exhaust gas adsorption component 3 to rotate, but at this time it is still in contact with the exhaust gas adsorption component 3, so that it still does not leak.

[0051] In addition, the sealing ring 323 can slide horizontally in the grooves formed on the pipe a1 and the pipe b2 through the spring member.

[0052] Embodiment 2

[0053] The components that are the same or corresponding to those in the first embodiment are marked with the same reference numerals as those in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that:

[0054] Furthermore, the interior of the housing 4 is a low-pressure environment.

[0055] In this embodiment, by setting the shell 4 to a low-pressure environment, the porous solid particles in the storage bin 313 are connected to the pipe a and the pipe b to a high-pressure environment. Once the shell 4 is transferred out to a low-pressure environment, the porous solid particles in the storage bin 313 are in a low-pressure environment, and the adsorbent is regenerated through the change in air pressure difference, thereby increasing the number of cycles and improving enterprise benefits.
