Description

Technical Field

[0001] This utility model relates to the field of chlorination reaction recovery technology, specifically a chlorination reaction recovery and reuse device. Background Technology

[0002] In the deep processing of chlorinated alkanes and chlorinated aromatics using hydrogen chloride as a byproduct, the chlorination reaction waste gas contains some recoverable particulate matter. For example, during the chlorination reaction of benzene, chlorobenzene may be formed first. If the waste gas contains chlorobenzene particles, they can be recovered. The recovered chlorobenzene can be sold directly as a product or further fed into the reaction system to continue the chlorination reaction and generate more advanced chlorinated products such as dichlorobenzene.

[0003] In traditional recycling processes, taking the chlorination reaction of benzene as an example, benzene and chlorine react with a catalyst to produce chlorobenzene and hydrogen chloride, releasing a large amount of heat during the reaction. This heat raises the temperature of the reaction system, and the generated waste gas also carries some heat. During recycling, the heat from the waste gas easily causes the recycling device to overheat in traditional recycling processes. High temperatures damage the surface fiber structure of the filter device, reducing its adsorption and retention capacity for particulate matter, thus affecting the recycling efficiency. Based on this, this application provides a chlorination reaction recycling and reuse device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a chlorination reaction recovery and reuse device, which solves the problem that in traditional recovery processes, the exothermic chlorination reaction causes the waste gas to carry a large amount of heat, leading to a rise in the temperature of the recovery device. High temperatures can damage the fiber structure of the filter device surface, reducing its adsorption and retention capacity for particulate matter and affecting recovery efficiency.

[0005] The chlorination reaction recovery and reuse device of this utility model includes an installation cylinder for installation. A purification component is provided on the inner side of the installation cylinder. Pipe components are provided on the top and bottom sides of the purification component for introducing the gas after the reaction. A base is provided at the bottom of the installation cylinder for maintaining the stability of the installation cylinder. The purification component includes a purification cylinder, a cooling channel is provided in the middle of the purification cylinder, a circular limiting area is provided in the middle of the inner side of the cooling channel, and a slot arranged in a ring array is provided on the inner wall of the circular limiting area. One or more cooling plates are installed in the slots for cooling the reaction gas. A filter element is installed at the bottom of the cooling channel. A temporary storage area is fitted on the outside of the filter element, and an outlet is opened on the outside of the temporary storage area for use with the pipeline components to discharge the filtered gas.

[0006] As a further improvement of this utility model, the cooling plate includes a plate body, the surface of which is provided with through holes arranged at uniform intervals for the passage of reaction gas, and a filling groove is provided in the middle of the plate body between every two sets of through holes, the filling groove being filled with a cooling medium for cooling the plate body.

[0007] As a further improvement of this utility model, the outer side of the plate is provided with flanges that are equally spaced, and the flanges are adapted to the slots provided on the inner side of the purification cylinder for positioning the plate.

[0008] As a further improvement of this utility model, a positioning groove is provided in the middle of one side of the plate. Each pair of plates is fixed to the support component through the positioning groove, so that a fixed distance is maintained between the two plates, which facilitates the passage of the reaction gas.

[0009] As a further improvement of this utility model, the filter element includes a body, which is arranged in a frustum shape. Both the top and bottom of the body are provided with sealing caps. An air inlet is installed at the sealing cap at the top, which is used to fit with the bottom of the cooling channel for the passage of gas.

[0010] As a further improvement of this utility model, a temporary storage cavity is provided on the inner side of the filter element to filter particulate matter contained in the reaction gas.

[0011] As a further improvement of this utility model, a guide tube is provided at the top of the cooling channel. The top diameter of the guide tube is larger than the bottom diameter. The top of the guide tube is adapted to the pipe component, forcing the reaction gas to enter the cooling channel quickly.

[0012] As a further improvement of this utility model, two sets of symmetrically arranged fixing frames are provided in the middle of the inner side of the mounting cylinder, and the fixing frame located at the top of the mounting cylinder is sealed and connected to the sealing groove opened at the top of the purification cylinder.

[0013] As a further improvement of this utility model, a sealing component is provided on one side of the mounting cylinder. The sealing component includes a sealing plate. One side of the sealing plate is connected to one side of the mounting cylinder by a hinge, and a handle is provided in the middle of the sealing plate to facilitate opening the sealing plate.

[0014] As a further improvement of this utility model, the pipeline component includes an air inlet pipe and an air outlet pipe, the air inlet pipe being adapted to the top of the guide tube, and the air outlet pipe being connected to the outlet of the temporary storage area.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes an aluminum alloy cooling plate with excellent thermal conductivity. The evenly distributed perforations on the surface allow exhaust gas to pass through smoothly and make full contact with the plate. The cooling medium (such as water or coolant) in the central filling groove can quickly absorb the heat of the exhaust gas, effectively reducing the exhaust gas temperature and preventing high temperature from damaging the subsequent recovery device. This improves the overall efficiency of the device in recovering particulate matter. The flange on the outer side of the plate matches the groove on the inner side of the purification cylinder, which positions the plate and ensures that the cooling plate is accurately positioned in the cooling channel. This prevents the cooling plate from shaking or shifting during the exhaust gas flow, thus ensuring the stability of the cooling effect. Furthermore, the positioning groove and support components maintain a fixed distance between adjacent cooling plates, ensuring that the exhaust gas can flow evenly between the cooling plates, thus improving cooling efficiency and creating favorable conditions for the subsequent filter element to effectively filter particulate matter. The filter element body is truncated cone-shaped, which increases the contact area with the gas and facilitates the uniform flow of gas inside the filter element, making the gas more evenly distributed throughout the entire filter element space and improving the filtration efficiency of particulate matter in the reaction gas.

[0016] Meanwhile, the sealing caps at the top and bottom of the filter element ensure that gas does not leak from the top and bottom. In particular, the air inlet on the top sealing cap is adapted to the bottom of the cooling channel, and the edges are smoothly treated to ensure that the gas flows smoothly into the filter element and reduces flow resistance. The bottom sealing cap is sealed with sealing material to ensure good sealing effect. Furthermore, the temporary storage chamber inside the filter element provides diffusion space for the gas, allowing the particulate matter in the gas to fully contact the filter material of the filter element body. The microporous structure of the filter material can effectively intercept most of the particulate matter, realizing the effective collection of recyclable particulate matter.

[0019] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0020] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0021] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4In the deep processing of chlorinated alkanes and chlorinated aromatics using hydrogen chloride as a byproduct, the waste gas from the chlorination reaction contains recyclable particulate matter, such as chlorobenzene particles generated from the chlorination reaction of benzene. After recovery, these particles can be sold directly or used to continue the reaction to produce higher chlorinated products.

[0022] In traditional recycling processes, the exothermic chlorination reaction causes the waste gas to carry a large amount of heat, leading to a rise in temperature in the recycling device. High temperatures can damage the fiber structure on the surface of the filter device, reducing its ability to adsorb and retain particulate matter and affecting recycling efficiency.

[0023] To address the problems of traditional recycling devices, a chlorination reaction recycling and reuse device needs to be developed, including an installation cylinder 1 for installation, a purification component 5 inside the installation cylinder 1, and pipe components 3 on the top and bottom sides of the purification component 5 for introducing the gas after the reaction. A base 4 is provided at the bottom of the installation cylinder 1 to maintain the stability of the installation cylinder 1. The purification component 5 includes a purification cylinder 51, a cooling channel 57 is provided in the middle of the purification cylinder 51, a circular limiting area 511 is provided in the middle of the inner side of the cooling channel 57, and a slot 510 arranged in a ring array is provided on the inner wall of the circular limiting area 511. One or more cooling plates 59 are installed at the slot 510 for cooling the reaction gas. A filter element 54 is provided at the bottom of the cooling channel 57. A temporary storage area 56 is provided on the outside of the filter element 54. An outlet 55 is provided on the outside of the temporary storage area 56 to cooperate with the pipe component 3 to discharge the filtered gas.

[0024] The mounting cylinder 1 provides installation space for the purification component 5. The mounting cylinder 1 is typically made of a metal material with sufficient strength and corrosion resistance, such as stainless steel. During the chlorination reaction, the waste gas may contain corrosive substances such as hydrogen chloride. Stainless steel can resist the corrosion of these substances, ensuring the long-term stable operation of the device. The purification cylinder 51 is a closed cylindrical structure used to house components such as the cooling channel 57 and the filter element 54. The purification cylinder 51 is also made of corrosion-resistant material, and its inner wall is smoothed to reduce resistance to the flow of waste gas within the cylinder.

[0025] The cooling channel 57 is located in the middle of the purification cylinder 51, and a circular limiting area 511 is provided in the middle of its inner side. This circular limiting area 511 serves to fix the cooling plate 59. The inner wall of the circular limiting area 511 is machined with slots 510 arranged in a ring array. The slots 510 facilitate the installation and removal of the cooling plate 59, and at the same time ensure that the cooling plate 59 does not shake during operation.

[0026] Cooling plates 59 are installed in slots 510, and one or more can be installed as needed. Cooling plates 59 are typically made of a metal material with good thermal conductivity, such as aluminum alloy. Cooling plates 59 have internal coolant channels where the coolant circulates, absorbing heat from the exhaust gas and thus cooling the reacting gases. Water or other liquids with good cooling properties can be used as the coolant. When exhaust gas passes through cooling channels 57, it comes into full contact with cooling plates 59, and heat is rapidly transferred to the cooling plates 59, lowering the exhaust gas temperature. This prevents high temperatures from damaging subsequent components such as filter element 54 and improves recovery efficiency.

[0027] Filter element 54 is located at the bottom of cooling channel 57, and its main function is to filter particulate matter in exhaust gas. Filter element 54 is made of high-efficiency filter materials, such as fiber filter materials or activated carbon filter materials. Fiber filter materials have a large specific surface area and good filtration performance, which can effectively trap small particulate matter in exhaust gas; activated carbon filter materials have a strong adsorption capacity for organic matter, which can further purify exhaust gas. A temporary storage area 56 is provided on the outer side of filter element 54. The temporary storage area 56 is used to temporarily store the filtered gas, so that the gas is evenly distributed in the area, preparing it for subsequent discharge.

[0028] An outlet 55 is provided on the outer side of the temporary storage area 56. The outlet 55 is connected to the pipe component 3 and is used to discharge the filtered gas. The size and number of outlets 55 are designed according to the gas flow rate and subsequent processing requirements to ensure that the gas can be discharged smoothly.

[0029] Pipe components 3 are respectively installed on one side of the top and bottom of the purification component 5, mainly used for introducing the reacted gas. Pipe components 3 are made of corrosion-resistant materials, such as plastic or stainless steel pipes. The diameter of the pipes is selected according to the flow rate and pressure of the exhaust gas to ensure a stable flow of exhaust gas into the purification component 5. At the pipe connections, connectors with good sealing performance are used to prevent exhaust gas leakage.

[0030] The base 4 is located at the bottom of the mounting cylinder 1, and its function is to maintain the stability of the mounting cylinder 1. The base 4 is usually made of heavy metal material, such as cast iron. The shape of the base 4 can be designed according to the shape of the mounting cylinder 1 and the actual installation requirements, and is generally circular or square. Rubber pads or other shock-absorbing materials can be placed at the bottom of the base 4 to reduce vibration and noise during operation.

[0031] When the waste gas from the chlorination reaction of chloroalkanes and chloroaromatics enters the purification unit 5 through the pipe component 3, it first enters the cooling channel 57. Inside the cooling channel 57, the waste gas comes into full contact with the cooling plate 59, and the coolant within the cooling plate 59 absorbs heat from the waste gas, lowering its temperature. The cooled waste gas continues to flow downwards and enters the filter element 54. The filter element 54 filters out particulate matter in the waste gas, trapping the particles on its surface. The filtered gas then enters the temporary storage area 56, where it is evenly distributed before being discharged through the outlet 55 and the pipe component 3 for further treatment or recycling.

[0032] Through the above-described device and working process, this chlorination reaction recovery and reuse device can effectively solve the problem of reduced recovery efficiency caused by the heat of waste gas in traditional recovery devices, and improve the recovery efficiency of recoverable particulate matter in chlorination reaction waste gas.

[0033] Please see Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 as well as Figure 10 The cooling plate 59 includes a plate body 591. The surface of the plate body 591 is provided with through holes 593 arranged at uniform intervals for the passage of reaction gas. A filling groove 595 is provided in the middle of the plate body 591 between every two sets of through holes 593. The filling groove 595 is filled with a cooling medium for cooling the plate body 591.

[0034] The outer side of the plate 591 is provided with flanges 594 arranged at equal intervals. The flanges 594 are adapted to the slots 510 provided on the inner side of the purification cylinder 51 for positioning the plate 591.

[0035] A positioning groove 592 is provided in the middle of one side of the plate 591. Each pair of plates 591 is fixed to the support component through the positioning groove 592, so that a fixed distance is maintained between the two plates 591 to facilitate the passage of the reaction gas.

[0036] Plate 591 is the main structure of cooling plate 59, and is usually made of a metal material with good thermal conductivity and corrosion resistance, such as aluminum alloy. Aluminum alloy has high thermal conductivity, which can quickly transfer heat from the exhaust gas. At the same time, a dense oxide film can be formed on its surface to resist the erosion of corrosive substances in the chlorination reaction exhaust gas.

[0037] The surface of the plate 591 is provided with through holes 593 arranged at uniform intervals to ensure that the exhaust gas can pass through the plate 591 smoothly. When the exhaust gas after the reaction enters the cooling channel 57 and flows through the cooling plate 59, the through holes 593 provide a flow channel for the exhaust gas, so that the exhaust gas can fully contact the plate 591, thereby realizing the exchange of heat.

[0038] A filling groove 595 is provided in the middle of the plate 591 between every two sets of through holes 593. The filling groove 595 is manufactured during the processing of the plate 591 through a specific process, and its shape is usually a long and narrow rectangular groove. The filling groove 595 is filled with a cooling medium, such as water or coolant. Water has the advantages of high specific heat capacity, wide availability, and low cost, while coolant has better antifreeze and anti-corrosion properties. The cooling medium absorbs the heat transferred from the exhaust gas by the plate 591 in the filling groove 595, thereby reducing the temperature of the plate 591 and cooling the exhaust gas. To ensure the cooling effect, the cooling medium in the filling groove 595 can be continuously renewed by an external circulation system to keep the cooling medium at a low temperature, such as by connecting an external circulation pump, in conjunction with a water-cooling heat dissipation device, such as a computer water-cooling radiator, to meet the heat dissipation needs of the coolant. The outer side of the plate 591 is provided with flanges 594 arranged at equal intervals. The flanges 594 are integrally formed with the plate 591 and are outwardly protruding strips. The size and shape of the flanges 594 are adapted to the slots 510 provided on the inner side of the purification cylinder 51. When installing the cooling plate 59, align the flanges 594 with the slots 510, and then insert the cooling plate 59 along the direction of the slots 510 until the flanges 594 are fully engaged in the slots 510. In this way, the flanges 594 serve to position the plate 591, ensuring the accurate position of the cooling plate 59 within the cooling channel 57, preventing the cooling plate 59 from shaking or shifting during exhaust gas flow, and ensuring the stability of the cooling effect.

[0039] A positioning groove 592 is provided in the middle of one side of the plate 591. The positioning groove 592 is a recessed groove whose size and shape are designed according to the structure of the support component. Each pair of plates 591 is fixed to the support component assembly via the positioning groove 592. The support component is typically a structural component with a certain strength and stability, such as a metal rod or plastic rod. The two ends of the support component are inserted into the positioning grooves 592 of two adjacent plates 591, thereby connecting the two plates 591 together. In this way, a fixed distance is maintained between the two plates 591. This fixed distance is precisely calculated to ensure that the exhaust gas can pass smoothly between the two plates 591 while also ensuring sufficient contact time and contact area between the exhaust gas and the plates 591 to achieve a good cooling effect. Generally, the distance between the two plates 591 is between a few centimeters and tens of centimeters.

[0040] When the high-temperature exhaust gas from the chlorination reaction enters the cooling channel 57 of the purification component 5 through the pipe component 3, the exhaust gas first encounters the cooling plate 59. The exhaust gas flows through the through holes 593 on the surface of the plate 591, making full contact with the plate 591. The plate 591 absorbs the heat from the exhaust gas and transfers it to the cooling medium in the filling tank 595. The cooling medium carries away the heat through its own temperature rise. As the exhaust gas continues to flow in the cooling channel 57, its temperature gradually decreases after being cooled by multiple cooling plates 59. The flange 594 ensures the stable position of the cooling plate 59 in the cooling channel 57, while the positioning groove 592 and the support ensure a fixed spacing between adjacent cooling plates 59, allowing the exhaust gas to flow evenly between the cooling plates 59, improving cooling efficiency and creating favorable conditions for the subsequent filter element 54 to effectively filter particulate matter.

[0041] Please see Figure 3 , Figure 11 as well as Figure 12 The filter element 54 includes a body 542, which is frustum-shaped. Both the top and bottom of the body 542 are provided with sealing caps 541. An air inlet 543 is installed at the sealing cap 541 at the top, which is adapted to the bottom of the cooling channel 57 for the passage of gas.

[0042] The filter element 54 has a temporary storage chamber 544 on its inner side, which is used to filter particulate matter in the reaction gas.

[0043] The filter element 54 has a frustum-shaped body 542. On one hand, compared to a traditional cylindrical structure, the frustum-shaped structure has a larger base dimension for the same height and top size, increasing the contact area between the filter element 54 and the gas. When the reactant gas passes through the filter element 54, the larger contact area means more opportunities for particulate matter to be intercepted, thus improving filtration efficiency. On the other hand, the frustum-shaped structure facilitates gas flow within the filter element 54, allowing for more uniform gas distribution throughout the entire filter element 54 space and preventing localized excessively fast or slow gas flow rates. The body 542 is typically made of materials with excellent filtration performance, such as fiber filter media. This material has a rich microporous structure, effectively capturing small particulate matter in the exhaust gas.

[0044] A sealing cap 541 is provided on the top of the main body 542, which seals the top of the filter element 54 to prevent gas leakage. An air inlet 543 is installed on the top sealing cap 541, typically located at the center of the cap to ensure that gas flowing from the bottom of the cooling channel 57 enters the filter element 54 evenly. The size of the air inlet 543 is adapted to the bottom of the cooling channel 57; generally, the diameter of the air inlet 543 is slightly smaller than the bottom outlet diameter of the cooling channel 57 to ensure smooth gas flow into the filter element 54 while preventing gas leakage at the interface. The edges of the air inlet 543 are smoothed to reduce resistance to gas flow.

[0045] The bottom of the main body 542 is also provided with a sealing cover 541. The main function of the bottom sealing cover 541 is to seal the bottom of the filter element 54 to prevent the filtered gas from leaking out from the bottom. The bottom sealing cover 541 is tightly connected to the main body 542, and is usually sealed with sealing materials such as sealant or sealing gaskets to ensure a good sealing effect.

[0046] The filter element 54 has a storage chamber 544 enclosed on its inner side. The storage chamber 544 is a relatively enclosed space designed to filter particulate matter contained in the reaction gas. When the reaction gas enters the filter element 54 through the inlet 543, it diffuses within the storage chamber 544. During this process, particulate matter in the gas comes into contact with the filter material of the filter element 54 body 542. Due to the microporous structure of the filter material, most of the particulate matter is trapped on the surface or inside of the filter material, while the filtered gas continues to flow within the storage chamber 544 and is eventually discharged through the outlet 55 outside the storage area 56.

[0047] When the reaction gas, cooled by the cooling channel 57, flows out from the bottom of the cooling channel 57, it enters the filter element 54 through the air inlet 543 on the top sealing cover 541. The gas diffuses within the temporary storage chamber 544, making full contact with the filter material of the filter element 54 body 542. Particulate matter is intercepted by the filter material and remains on its surface or inside. The filtered gas continues to flow within the temporary storage chamber 544 and eventually exits through the outlet 55 outside the temporary storage area 56, entering subsequent processing or recycling stages. As the filtration process continues, particulate matter gradually accumulates on the surface of the filter element 54. When it accumulates to a certain level, the filter element 54 needs to be replaced or cleaned to ensure filtration efficiency and the normal operation of the device.

[0048] A guide tube 53 is provided at the top of the cooling channel 57. The top diameter of the guide tube 53 is larger than the bottom diameter. The top of the guide tube 53 is adapted to the pipe component 3, forcing the reaction gas to enter the cooling channel 57 quickly.

[0049] Two sets of symmetrically arranged fixing frames 52 are provided in the middle of the inner side of the mounting cylinder 1. The fixing frame 52 located at the top of the mounting cylinder 1 is sealed and connected to the sealing groove 58 opened at the top of the purification cylinder 51.

[0050] A sealing component 2 is provided on one side of the mounting cylinder 1. The sealing component 2 includes a sealing plate 22. One side of the sealing plate 22 is connected to one side of the mounting cylinder 1 by a hinge, and a handle 21 is provided in the middle of the sealing plate 22 to facilitate opening the sealing plate 22.

[0051] The pipe component 3 includes an air inlet pipe 32 and an air outlet pipe 31. The air inlet pipe 32 is adapted to the top of the guide tube 53, and the air outlet pipe 31 is connected to the outlet 55 of the temporary storage area 56.

[0052] A guide tube 53 is installed at the top of the cooling channel 57 in the chlorination reaction recovery and reuse device. The top diameter of the guide tube 53 is larger than its bottom diameter, giving it an overall shape that is wider at the top and narrower at the bottom. This design effectively guides the flow of the reaction gas. When the reaction gas flows into the guide tube 53 from the pipe component 3, the larger top diameter provides sufficient space for the gas to enter. As the gas flows downward, the bottom diameter of the guide tube 53 decreases, and according to fluid mechanics principles, the gas velocity increases accordingly. This forces the reaction gas to enter the cooling channel 57 quickly, improving the gas flow efficiency within the device and allowing for more timely cooling. This prevents heat accumulation caused by gas stagnation in the guide tube 53, further reducing the adverse effects of high temperatures on subsequent components. The top of the guide tube 53 is fitted to the pipe component 3, and the two are sealed together to prevent gas leakage. This fitting design allows the gas in the pipe component 3 to smoothly transition into the guide tube 53, ensuring a smooth gas transport process.

[0053] Two sets of symmetrically arranged fixing frames 52 are provided on the inner center of the mounting cylinder 1. The function of the fixing frames 52 is to fix and support the purification cylinder 51, ensuring the stable position of the purification cylinder 51 within the mounting cylinder 1. The fixing frame 52 located at the top of the mounting cylinder 1 is sealed and connected to the sealing groove 58 formed at the top of the purification cylinder 51. Sealing material, such as a rubber sealing ring, is usually placed in the sealing groove 58. When the fixing frame 52 and the sealing groove 58 are engaged, the sealing material is compressed, forming a good sealing effect and preventing the reactive gas from leaking out from the connection between the purification cylinder 51 and the mounting cylinder 1. This sealed connection not only ensures the airtightness of the device but also enhances the connection stability between the purification cylinder 51 and the mounting cylinder 1, making the entire device more reliable during operation.

[0054] A sealing component 2 is provided on one side of the mounting cylinder 1, which is mainly composed of a sealing plate 22. One side of the sealing plate 22 is connected to one side of the mounting cylinder 1 by a hinge, allowing the sealing plate 22 to rotate around the hinge like a door. This connection method facilitates the inspection and maintenance of the components inside the mounting cylinder 1. When it is necessary to inspect, replace, or clean the purification component 5, cooling plate 59, filter element 54, etc., simply open the sealing plate 22. A handle 21 is provided in the middle of the sealing plate 22. The handle 21 is designed according to ergonomic principles, making it easy for the operator to grip and apply force to open the sealing plate 22. The surface of the handle 21 is usually treated with anti-slip treatment, such as using a frosted process or covering with anti-slip material, to ensure that the operator's hand will not slip when opening the sealing plate 22, improving the safety and convenience of operation.

[0055] Piping component 3 includes an inlet pipe 32 and an outlet pipe 31. The inlet pipe 32 transports the reacted gas into the device. It is fitted to the top of the guide tube 53, and the two are sealed together to prevent gas leakage during transport. The diameter of the inlet pipe 32 is designed based on the flow rate and pressure of the reacting gas to ensure smooth entry into the guide tube 53. The outlet pipe 31 connects to the outlet 55 of the temporary storage area 56, and its function is to discharge the cooled and filtered gas from the device. The diameter of the outlet pipe 31 is also designed based on the gas flow rate and pressure to ensure smooth gas discharge. The outlet pipe 31 and outlet 55 are also sealed together to prevent leakage of the filtered gas. In practical use, the inlet pipe 32 and outlet pipe 31 are typically connected to other piping systems, such as waste gas collection pipes and treated gas discharge pipes, to achieve continuous transport and treatment of the reacting gas.

[0056] The reacted gas enters the guide tube 53 through the inlet pipe 32. Due to the special shape of the guide tube 53, the gas quickly enters the cooling channel 57. In the cooling channel 57, the gas comes into contact with the cooling plate 59, and its temperature decreases. Next, the cooled gas enters the filter element 54 for filtration, where particulate matter is trapped. The filtered gas then enters the temporary storage area 56. Finally, the filtered gas exits the device through the outlet pipe 31. Throughout the process, the fixing frame 52 and the sealing groove 58 ensure the seal and stability between the purification cylinder 51 and the mounting cylinder 1, while the sealing component 2 facilitates device maintenance.

[0057] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
