Description

Technical Field

[0001] This utility model relates to the technical field of waste gas treatment equipment, and in particular to a tail gas treatment device for industrial production. Background Technology

[0002] With the rapid development of industrialization, various factories generate industrial exhaust gases containing harmful substances during the production process. In order to respond to environmental protection requirements and protect the ecological environment, these exhaust gases must be purified before they can be discharged. Among the many exhaust gas treatment technologies, adsorption is widely used because of its wide applicability and good treatment effect. Its core treatment unit is usually an adsorption tower or box filled with adsorption materials such as activated carbon.

[0003] However, the adsorption material inside the adsorption tower or chamber will reach adsorption saturation after a period of use, losing its purification capacity and requiring periodic replacement. In existing technologies, these core processing units are mostly fixedly connected to the inlet and outlet main gas pipelines by welding flange heating rings. This rigid connection structure makes the entire device an inseparable whole.

[0004] When the adsorbent material needs to be replaced, the drawbacks of this fixed connection method become apparent. Maintenance personnel must first shut down the entire production line for an extended period before cutting the welded flanges to separate the core processing unit. After replacing the material, complex alignment, welding, and sealing operations are required. The entire process is not only extremely time-consuming and labor-intensive but also demands a high level of technical skill from the operators. The prolonged downtime directly leads to a significant reduction in production efficiency and economic losses. This inflexible structural design severely restricts the convenience of equipment maintenance and the continuity of production.

[0005] Therefore, this utility model proposes an exhaust gas treatment device for industrial production to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems in the existing technology of exhaust gas treatment devices for industrial production, such as the complex and time-consuming replacement process of the core treatment unit and the difficulty in guaranteeing the sealing reliability after disassembly and assembly, this utility model aims to provide an industrial exhaust gas treatment device with an improved structure that can effectively solve the above problems.

[0007] This utility model provides an exhaust gas treatment device for industrial production, including: a coarse filter device with an air inlet pipe, an exhaust device with an exhaust pipe, and a modular mechanism with a connecting pipe; the ports of the aforementioned air inlet pipe, connecting pipe, and exhaust pipe are all fixedly connected with pipe edges; and a connecting mechanism for connecting the aforementioned components.

[0008] The connecting mechanism includes an upper clamping plate and a lower clamping plate that are rotatably connected by a second rotating shaft. The inner sides of the upper clamping plate and the lower clamping plate are respectively provided with clamping grooves for holding the pipe edge.

[0009] Furthermore, the outer wall of the upper clamping plate is fixedly connected to the upper clamping plate, and the outer wall of the lower clamping plate is fixedly connected to the lower clamping plate; the connecting mechanism also includes a bolt rotatably connected to the lower clamping plate via a first rotating shaft, and a threaded thread that engages with the bolt; the bolt is rotatably embedded in the groove of the upper clamping plate, and the threaded thread abuts against the upper surface of the upper clamping plate when tightened, thereby securely locking the upper and lower clamping plates together through this structural combination.

[0010] Preferably, the modular mechanism includes an outer frame, a housing detachably disposed inside the outer frame, and a sealing cover plate rotatably connected to the outer frame via a first hinge.

[0011] Preferably, the top opening of the box is rotatably connected to the box lid via a second hinge.

[0012] Preferably, the lid is provided with a locking assembly, which includes a knob fixedly installed on the outer surface of the lid, a rotating column fixed coaxially with the knob and passing through the lid, and a locking plate fixed to the end of the rotating column. The box body is provided with a locking hole for the locking plate to be screwed in and locked.

[0013] Preferably, several air holes are provided on the opposite side walls of the box, and a handle is fixedly connected to the top of the box lid.

[0015] Preferably, the outer periphery of the screw thread is fixedly connected with a shank for driving its rotation.

[0016] Preferably, the exhaust device also includes an exhaust fan located inside the exhaust pipe channel and a chimney connected to the end of the exhaust pipe.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problems of long downtime and complicated and laborious disassembly and assembly when replacing core components of exhaust gas treatment devices in the prior art by setting up a modular mechanism that can be disassembled as a whole, and using a connection mechanism composed of upper clamping plate, lower clamping plate and bolts and threads for quick locking and separation. It achieves the technical effects of quick replacement of core treatment unit, non-stop maintenance, and improved production efficiency.

[0018] 2. This utility model solves the problems of cumbersome operation procedures and inconvenient sealing when the adsorbent material is replaced by setting an independently removable box inside the modular mechanism and setting a locking cover assembly consisting of a knob, a rotating column and a locking plate on the box. It achieves the technical effect of simplifying maintenance steps and realizing rapid filling and reliable sealing of adsorbent material.

[0019] 3.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please refer to Figures 1 to 5This utility model provides an industrial exhaust gas treatment device, which aims to solve the problems of complex replacement process, long time consumption and insufficient sealing reliability of the core treatment unit of existing industrial exhaust gas treatment devices.

[0024] like Figure 1 As shown, the industrial production exhaust gas treatment device includes a coarse filter 1, a modular mechanism 2, and an exhaust device 4 arranged sequentially along the gas treatment path. The coarse filter 1 is provided with an air inlet pipe 101, and the exhaust device 4 is provided with an exhaust pipe 402. The two ends of the modular mechanism 2 are respectively provided with connecting pipes 212 for connecting to the air inlet pipe 101 and the exhaust pipe 402. In order to achieve quick disassembly and assembly, the ports of the air inlet pipe 101, the connecting pipe 212, and the exhaust pipe 402 are all fixedly connected with annular pipe edges 304 by welding. The device also includes a connecting mechanism 3 for detachably connecting the modular mechanism 2 to the coarse filter 1 and the exhaust device 4.

[0025] Specifically, refer to Figure 4 and Figure 5 The connecting mechanism 3 is a clamp-type quick-release structure, which includes an upper clamping plate 301 and a lower clamping plate 302 rotatably connected by a second rotating shaft 311. The inner sides of the upper clamping plate 301 and the lower clamping plate 302 are respectively integrally formed with clamping grooves 303 for holding the pipe edge 304. An upper clamping plate 305 is fixedly connected to the outer wall of the upper clamping plate 301, and a lower clamping plate 306 is fixedly connected to the outer wall of the lower clamping plate 302. The connecting mechanism 3 also includes a bolt rotatably connected to the lower clamping plate 306 by a first rotating shaft 308. 307, and a threaded thread 309 that is threaded into the bolt 307. The upper clamping plate 305 has a groove for the bolt 307 to be rotatably inserted. During the locking operation, the bolt 307 flips upward and is inserted into the groove of the upper clamping plate 305. Then the threaded thread 309 is tightened. The lower end face of the threaded thread 309 abuts against the upper surface of the upper clamping plate 305. A strong axial clamping force is generated through the action of the threaded pair, thereby firmly locking the upper clamping plate 301 and the lower clamping plate 302 onto the pipe edge 304.

[0026] To solve the above technical problems, the internal structure of the modular mechanism 2 and its cooperation with the outer frame 201 enable the core processing unit to be quickly extracted and inserted as a whole.

[0027] Please refer to Figure 2 and Figure 3The modular mechanism 2 includes an outer frame 201 as the main support structure and a box 206 that is pluggably disposed inside the outer frame 201. The opening end of the outer frame 201 is rotatably connected to a sealing cover 203 for achieving overall sealing via a first hinge 202. The top opening of the box 206 is rotatably connected to a box cover 213 via a second hinge 205. The top of the box cover 213 is fixedly connected to a handle 204 for easy gripping by the operator. When it is necessary to replace the absorbent material, the maintenance personnel can first open the sealing cover 203, and then pull the entire box 206 together with its box cover 213 out from the partition guide rail inside the outer frame 201 by pulling the handle 204.

[0028] Meanwhile, to ensure the convenience of replacing the adsorbent material and the airtightness of the box 206, a special locking assembly is provided on the box cover 213. The locking assembly includes a knob 208 fixedly installed on the outer surface of the box cover 213, a rotating column 209 coaxially fixed with the knob 208 and passing through the box cover 213, and a locking plate 210 fixed to the end of the rotating column 209. The box 206 has a corresponding locking hole 211 for the locking plate 210 to be screwed in and locked. When locking, first align the locking plate 210 with the insertion hole of the locking hole 211 and push it in. Then rotate the knob 208. The knob 208 drives the rotating column 209 and the locking plate 210 to rotate synchronously, so that the locking plate 210 rotates in the limiting cavity inside the locking hole 211 to a position that is misaligned with the insertion hole, thereby firmly locking the box cover 213 onto the box 206. This locking structure ensures the speed of operation and the reliability of locking.

[0029] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, in order to enhance the sealing performance of the connecting mechanism 3 and prevent harmful gases from leaking from the pipe connection, refer to Figure 4 An annular rubber sealing ring is embedded in the inner wall of the clamping plate groove 303. When the upper clamping plate 301 and the lower clamping plate 302 clamp the pipe edge 304, the rubber sealing ring is squeezed and deformed, which can effectively fill the tiny gap between the pipe edge 304 and the clamping plate groove 303.

[0030] As another preferred embodiment, to facilitate the operator in applying sufficient torque to tighten thread 309, refer to Figure 5 A radially extending shank 310 is fixedly connected to the outer periphery of the screw thread 309 by welding, allowing the operator to perform a labor-saving rotation operation by holding the shank 310.

[0031] As a further implementation method, in order to ensure effective flow of exhaust gas within the modular mechanism 2 and sufficient contact with the adsorption material, refer to Figure 3Several air holes 207 are arranged in an array on the opposite side walls of the box 206. Gas can enter the interior of the box 206 from one side air hole 207, pass through the adsorbent material filled inside, and then flow out from the other side air hole 207.

[0032] As a preferred embodiment of the power and emission section of this device, refer to Figure 1 The exhaust device 4 also includes an exhaust fan 401 located inside the flow channel of the exhaust pipe 402 and a chimney 403 connected to the end of the exhaust pipe 402. The operation of the exhaust fan 401 provides negative pressure suction for the gas flow in the entire device, and the treated clean gas is finally discharged into the air through the chimney 403.

[0033] The working principle of this industrial exhaust gas treatment device is as follows: During equipment operation, the exhaust gas generated in industrial production is first introduced into the coarse filter device 1 to remove large particulate impurities. Then, the gas enters the intake pipe 101. Under the negative pressure suction generated by the exhaust fan 401 in the exhaust device 4 at the end of the device, the gas passes through the first connecting mechanism 3 and enters the connecting pipe 212 of the modular mechanism 2. The gas then passes through the outer frame 201 and enters the interior of the housing 206 through the air hole 207 on one side of the housing 206. It comes into full contact with the adsorbent material filled therein, and the harmful components are adsorbed and purified. The purified gas flows out from the air hole 207 on the other side of the housing 206, and after collection, it enters the exhaust pipe 402 through the connecting pipe 212 at the other end and the second connecting mechanism 3, and is finally discharged through the chimney 403.

[0034] When the internal adsorbent material needs to be replaced, the maintenance personnel first operate the two connecting mechanisms 3 located at both ends of the modular mechanism 2. By turning the screw 310, the screw 309 is rotated in the opposite direction on the bolt 307 to loosen it. Then, the bolt 307 is unscrewed from the groove of the upper clamping plate 305 and flipped downward. At this time, the upper clamping plate 301 can be opened upward around the second rotating shaft 311, thereby quickly disassembling the entire modular mechanism 2 from the main pipe. Then, the pre-prepared spare modular mechanism 2 can be installed, and the connecting mechanism 3 is operated in the reverse order to lock it. The whole process does not require the production line to be stopped. For the disassembled modular mechanism 2, the operator opens its sealing cover 203, pulls out the inner box 206 through the handle 204, and then unlocks the box cover 213 by rotating the knob 208 to drive the locking plate 210. After replacing the failed adsorbent material inside, it is locked again. The modular mechanism 2 is then prepared as a spare part for the next replacement cycle.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
