Description

Technical Field

[0001] This utility model relates to the field of environmental protection equipment technology, and in particular to a closed collection and treatment device for acid mist in the pretreatment of galvanizing production lines. Background Technology

[0002] The acid mist enclosed collection and treatment device for the pretreatment stage of a galvanizing production line is a specialized piece of equipment used to enclose, collect, and treat the acid mist generated during the pretreatment stage. The main purpose of this device is to reduce acid mist pollution, protect the production environment, and simultaneously improve production efficiency and product quality.

[0003] In the pretreatment stage of the galvanizing production line, when workpieces enter the pickling tank for pickling, the pickling tank and its surrounding area are sealed off by a closed hood to prevent the spread of acid mist. Simultaneously, a collection system draws in the acid mist from the closed hood and transports it to a treatment unit for processing. After entering the treatment unit, the collected acid mist first undergoes spray neutralization treatment in a spray tower. The spray tower is equipped with spray devices and a packing layer. The spray liquid (usually an alkaline solution) comes into contact with the acid mist and undergoes a neutralization reaction, generating harmless substances such as salts and water. Then, the neutralized exhaust gas enters the activated carbon adsorption box within the treatment unit for further purification to remove residual harmful substances, thereby meeting national and local emission standards.

[0004] To ensure the stability and reliability of the waste gas treatment effect, the adsorbent material in the treatment device needs to be replaced after a period of use. Currently, when replacing the adsorbent material in the treatment device, it is necessary to first shut down the device that treats acid mist waste gas and cut off the acid mist waste gas, and then manually remove the adsorbent material for replacement. This replacement is inconvenient and will affect the treatment efficiency of acid mist waste gas. Utility Model Content

[0005] The purpose of this invention is to solve the problem mentioned in the background art above, where replacing the adsorbent material in the current treatment device requires first shutting down the device for treating acid mist exhaust gas and cutting off the acid mist exhaust gas, and then manually removing and replacing the adsorbent material, which is inconvenient and affects the treatment efficiency of acid mist exhaust gas.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A closed-loop collection and treatment device for acid mist in the pretreatment of a galvanizing production line includes a spray tower for spraying and neutralizing acid mist exhaust gas. A filter element is provided above the spray tower to adsorb and filter the neutralized acid mist exhaust gas. The spray tower and the filter element are connected by a pipeline. The filter element includes an adsorbent element that is easy to replace and a treatment box. The adsorbent element is rotatably installed in the treatment box.

[0008] Preferably, the filter element further includes a sealing block, which is disposed in the processing box. The sealing block has a rotating groove, and a rotating block is rotatably disposed in the rotating groove. The rotating block has a through hole, and the adsorption element is disposed in the through hole. The rotating block can be rotated in the rotating groove by bearings, which can prevent acid mist exhaust gas from leaking out from the gap between the rotating groove and the rotating block. The filter element removes harmful substances in the acid mist exhaust gas.

[0009] Preferably, the sealing block has an air outlet and an air inlet on its upper and lower sides, respectively, and the two ends of the through hole on the rotating block correspond to the air outlet and the air inlet, respectively. The acid mist exhaust gas enters the through hole from the air inlet and is discharged from the air outlet.

[0010] Preferably, the enclosed block is provided with a driving device. The output shaft of the driving device passes through the enclosed block and is connected to the rotating block. The driving device can be a motor. The driving device can drive the rotating block to rotate, thereby rotating the adsorption component that needs to be replaced to the top for easy replacement by the staff.

[0011] Preferably, the rotating block has a mounting plate inside the through hole, and the mounting plate has a fixing member. The adsorption member is fixed in the through hole by the fixing member. The fixing member can fix the adsorption member to the mounting plate, thereby fixing it in the through hole.

[0012] Preferably, the adsorption element includes an adsorption cylinder, which contains adsorption material for removing residual harmful substances in the waste gas. Both ends of the adsorption cylinder are provided with baffles to block the adsorption material. When in use, the baffles are perforated plates. Acid mist waste gas enters the adsorption cylinder through the perforations on the baffles, and the adsorption material in the adsorption cylinder removes harmful substances from the acid mist waste gas.

[0013] Preferably, the fixing component includes a fixing plate, a rotating plate on the outer side of the fixing plate, and a connecting rod on the inner side of the fixing plate. The connecting rod is threadedly connected to the mounting plate, and the connecting rod can be moved by rotating through the threaded connection.

[0014] Preferably, the outer end of the adsorption cylinder is provided with a connecting plate, and the connecting plate has a through hole for the fixing plate to pass through. The connecting plate is clamped between the fixing plate and the mounting plate, and the fixing plate can fix the connecting plate on the fixing plate, thereby fixing the adsorption cylinder on the rotating block.

[0015] Preferably, the connecting plate is provided with a limiting rod to limit the movement of the fixed plate. The limiting rod can limit the rotation of the fixed plate, making it easier for the operator to align the fixed plate with the through hole when rotating it.

[0016] Preferably, a connecting ring is provided in the through hole on the rotating block. The connecting ring is used for docking between the inner ends of the two adsorption cylinders.

[0018] This invention uses an adsorption element to remove harmful substances from acid mist exhaust gas. The adsorption element is located inside a rotating block, and the adsorption element can be rotated by rotating the rotating block. This allows the adsorption element that needs to be replaced to be rotated to the top for easy replacement by the staff. Moreover, when replacing the adsorption element, the new adsorption element can be installed first, and then the old adsorption element can be removed. This means that the workers do not need to stop the machine when replacing the adsorption element, and it does not affect the treatment efficiency of acid mist exhaust gas.

[0032] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity. Example

[0033] Please see Figures 1-7A closed collection and treatment device for acid mist in the pretreatment of a galvanizing production line includes a spray tower 1, which is used for spraying and neutralizing acid mist exhaust gas. A filter element 2 is provided above the spray tower 1 to adsorb and filter the neutralized acid mist exhaust gas. The spray tower 1 and the filter element 2 are connected by a pipeline. The filter element 2 includes an adsorbent element 24 that is easy to replace and a treatment box 21. The adsorbent element 24 is rotatably installed in the treatment box 21. When in use, there are two adsorbent elements 24, and both adsorbent elements 24 are installed in the treatment box 21.

[0034] Furthermore, the filter element 2 also includes a sealing block 22, which is located in the treatment box 21. The sealing block 22 has a rotating groove, and a rotating block 23 is rotatably mounted in the rotating groove. The rotating block 23 has a through hole 231, and the adsorbent 24 is located in the through hole 231. The rotating block 23 can rotate in the rotating groove via a bearing, which can prevent acid mist exhaust gas from leaking out from the gap between the rotating groove and the rotating block 23. The filter element 2 removes harmful substances in the acid mist exhaust gas. The sealing block 22 is equipped with a driving device, and the output shaft of the driving device passes through the sealing block 22 and is connected to the rotating block 23. The driving device can be a motor, which can drive the rotating block 23 to rotate, thereby rotating the adsorbent 24 that needs to be replaced to the top for easy replacement by the staff.

[0035] The upper and lower sides of the sealed block 22 are respectively provided with an air outlet 222 and an air inlet 221. The two ends of the through hole 231 on the rotating block 23 correspond to the air outlet 222 and the air inlet 221 respectively. The acid mist exhaust gas enters the through hole 231 from the air inlet 221 and is discharged from the air outlet 222.

[0036] Furthermore, a mounting plate 232 is provided inside the through hole 231 on the rotating block 23, and a fixing member 25 is provided on the mounting plate 232. The adsorption member 24 is fixed in the through hole 231 by the fixing member 25. The fixing member 25 can fix the adsorption member 24 on the mounting plate 232, thereby fixing it in the through hole 231. A connecting ring 233 is provided inside the through hole 231 on the rotating block 23. The connecting ring 233 is used for docking between the inner ends of the two adsorption cylinders 241. The connecting ring 233 can better dock the two adsorption cylinders 241 together, so that the two adsorption cylinders 241 can communicate with each other.

[0037] As should be added, the adsorption element 24 includes an adsorption cylinder 241, which contains adsorption material for removing residual harmful substances in the waste gas. Both ends of the adsorption cylinder 241 are equipped with baffles 243 to block the adsorption material. When in use, the baffles 243 are perforated plates. The acid mist waste gas enters the adsorption cylinder 241 through the mesh on the baffles 243, and the adsorption material in the adsorption cylinder 241 removes harmful substances from the acid mist waste gas.

[0038] It should be noted that the fixing component 25 includes a fixing plate 251, a rotating plate 252 on the outer side of the fixing plate 251, and a connecting rod 253 on the inner side of the fixing plate 251. The connecting rod 253 is threadedly connected to the mounting plate 232. The connecting rod 253 can be moved by rotating through the threaded connection. The fixing component 25 makes it easier for the staff to quickly assemble and disassemble the adsorption component 24. The outer end of the adsorption cylinder 241 is provided with a connecting plate 242. The connecting plate 242 has a through hole 244 for the fixing plate 251 to pass through. The connecting plate 242 is clamped between the fixing plate 251 and the mounting plate 232. The fixing plate 251 can fix the connecting plate 242 on the fixing plate 251, thereby fixing the adsorption cylinder 241 on the rotating block 23.

[0039] The connecting plate 242 is provided with a limiting rod 245 to limit the fixed plate 251. The limiting rod 245 can limit the rotation of the fixed plate 251, making it easier for the staff to align the fixed plate 251 with the through hole 244 when rotating it.

[0040] When this utility model is in use, when the acid mist exhaust gas reaches the spray tower 1, the spray tower 1 sprays and neutralizes the acid mist exhaust gas. The neutralized acid mist exhaust gas enters the closed block 22 through the air inlet 221, and then enters the adsorption cylinder 241. The adsorption material in the adsorption cylinder 241 adsorbs the acid mist exhaust gas. The treated acid mist exhaust gas is discharged into the air from the air outlet 222.

[0041] After prolonged filtration and adsorption of acid mist exhaust gas, filter element 2 needs to be replaced (lower adsorption element 24) to ensure effective adsorption and removal. The upper rotating plate 252 is rotated counter-clockwise until the fixing plate 251 aligns with the perforation 244 on the new adsorption element 24, allowing the new adsorption element 24 to be inserted into the through hole 231. The fixing plate 251 passes through the perforation 244, positioning the connecting plate 242 on the adsorption element 24 below the fixing plate 251. Then, the fixing plate 251 is rotated clockwise until it presses down on the connecting plate 242, thus securing the new adsorption element 24 within the rotating block 23. The drive is then activated. The drive equipment's output shaft rotates the rotating block 23 180 degrees, which can rotate the old adsorption component 24 from below to the top and rotate the new adsorption component 24 installed above to the bottom for use. Then, the rotating plate 252 on the old adsorption component 24 is rotated counterclockwise so that the side of the fixing plate 251 touches the limiting rod 245. At this time, the fixing plate 251 can be aligned with the perforation 244. Then, the adsorption cylinder 241 is pulled outward, and the fixing component 25 passes through the perforation 244, which can pull the adsorption cylinder 241 outward and remove it, making it convenient for the staff to replace the adsorption material in the adsorption cylinder 241. Moreover, the staff can quickly replace the adsorption material without stopping the machine.

[0042] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
