Description

Technical Field

[0001] This utility model relates to the field of reclaimed rubber production technology, specifically to a purification device for escaping flue gas during reclaimed rubber production. Background Technology

[0002] Reclaimed rubber is one of the main raw materials in the rubber manufacturing industry. It is a recyclable resource with wide availability and low price. The production process of reclaimed rubber emits various volatile organic pollutants, as well as water vapor and small amounts of rubber powder particles. Direct emission of these waste gases can affect the surrounding environment and produce a foul odor. Therefore, waste gas treatment is particularly crucial in reclaimed rubber production.

[0003] Existing technologies employ adsorption, absorption, condensation, combustion, pulsed corona discharge, low-temperature plasma, photocatalytic oxidation, ozone oxidation, and biological treatment to treat waste gas from reclaimed rubber production, which are relatively effective for handling large volumes of waste gas. However, with increasingly stringent standards for organic waste gas purification, in addition to uniformly treating waste gas from mixers and rubber mixing processes, it is also necessary to purify the escaping low-concentration flue gas. Currently, reclaimed rubber production lacks collection and treatment devices for these escaping flue gas. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the defects in the treatment of escaping flue gas in the prior art, thereby providing an escaping flue gas purification device for the production of reclaimed rubber.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A purification device for fume produced from recycled rubber includes multiple parallel chambers, a collection device, a filtration device, a washing device, a photocatalytic device, and an emission device. The collection device, filtration device, washing device, photocatalytic device, and emission device are connected sequentially by pipelines. The collection device is installed on the chamber and includes a main collection pipe and multiple sets of collection branch pipes. The main collection pipe is connected to the filtration device. Each set of collection branch pipes is connected at one end to the chamber and at the other end to the main collection pipe. The number of collection branch pipes corresponds to the number of chambers. A sampling structure is provided between the photocatalytic device and the emission device.

[0007] By adopting the above technical solution, an escaping flue gas purification device is added to the existing waste gas treatment system to collect and purify the escaping flue gas during the mixing tank production process. Escaped flue gas is different from production waste gas; its concentration is variable, its air volume is low, and its dispersion is uncertain. Therefore, it needs to be collected from multiple angles and then treated uniformly. The escaping flue gas treatment process is somewhat simplified compared to the waste gas treatment process, but sampling and testing are still required during subsequent emissions to ensure that it meets emission standards. The collection device set up in this application can collect and purify the escaping flue gas in the working chamber from multiple angles and all directions, and transport it to the subsequent treatment equipment through pipelines to ensure the purification effect and improve the cleanliness and environmental friendliness of the reclaimed rubber production process.

[0008] Furthermore, each set of collection pipes includes two first collection pipes, two second collection pipes, and one sidewall collection pipe. The first collection pipes are arranged opposite each other in the middle of one side of the top of the chamber, and the second collection pipes are arranged near both ends of the top of the chamber. The diameter of the first collection pipe is larger than that of the second collection pipe. The sidewall collection pipe is arranged on the sidewall of the chamber. A collection cover is also provided at the connection between the sidewall collection pipe and the chamber. The collection cover is in the shape of a truncated pyramid and the area of ​​the side closer to the chamber is larger than the area of ​​the side farther away from the chamber.

[0009] By adopting the above technical solution, multiple first collection pipes, second collection pipes and side wall collection pipes ensure comprehensive collection of the escaping flue gas. The first collection pipe is closer to the mouth of the mixing tank, so its diameter is larger than that of the second collection pipe. The escaping flue gas collected at the side wall collection pipe is mostly dusty and heavier, so a collection hood is set up to gather and settle it.

[0010] Furthermore, each set of collection pipes is also connected to a heat exchange structure, which includes a heat exchanger, a refrigerant outlet pipe, and a refrigerant inlet pipe. Each first collection pipe is fitted with a heat exchange sleeve, and the heat exchange sleeve has a connection inlet and a connection outlet offset from each other. The connection inlet is located above the connection outlet and is connected to the refrigerant outlet pipe. The connection outlet is connected to the refrigerant inlet pipe. A threaded pipe section extends integrally from the outer wall of the first collection pipe located inside the heat exchange sleeve.

[0011] By adopting the above technical solution, the overall heat of the flue gas near the mixing tank opening is relatively high, which can be exchanged using the heat exchange structure, thereby realizing the utilization of waste heat; the staggered connection inlet and connection outlet ensure that the refrigerant in the heat exchanger can fully contact the outer wall of the first collection pipe to achieve full heat exchange, and the threaded pipe section on the outer wall of the first collection pipe increases the contact area.

[0012] Furthermore, a rectangular snap-fit ​​platform is provided on the side wall of the chamber corresponding to the collection hood. A docking platform extends from the contact point between the collection hood and the snap-fit ​​platform. A sealing card and an inlet card extend from the snap-fit ​​platform. The sealing card and the inlet card are both arranged circumferentially along the snap-fit ​​platform and extend on the side of the snap-fit ​​platform close to the docking platform. The perimeter of the inlet card is smaller than that of the sealing card. A docking groove is provided on the docking platform corresponding to the sealing card and the inlet card. A dust collection net is also snapped onto the side of the snap-fit ​​platform away from the collection hood.

[0013] By adopting the above technical solution, the clamping platform and the docking platform are set up to fix the collection hood on the side wall of the working chamber. A double-layer clamping structure - sealing clip and inlet clip - is used to ensure that the collection hood is installed firmly and to reduce the escape of flue gas from the working chamber. The dust collection net reduces the amount of dust entering the subsequent flue gas purification equipment.

[0014] Furthermore, the filtration device is a multi-stage pre-filter, the water washing device includes a water washing tower, a demisting layer, multiple filling layers, and multiple spray layers. The demisting layer, multiple filling layers, and multiple spray layers are all disposed inside the water washing tower. The demisting layer is disposed at the top of the water washing tower. The filling layers and spray layers are disposed correspondingly and appear in pairs. The water washing device also includes a spray pump disposed outside the water washing tower and connected to the spray layers. The photocatalytic device is a UV photocatalytic device and is connected to the water washing device through an exhaust pipe. The photocatalytic device is connected to the emission device through an air supply pipe.

[0015] By adopting the above technical solution, the flue gas is collected, preliminarily filtered, and then enters the subsequent device. First, the flue gas is washed with an alkaline scrubbing tower to remove mist, and then the flue gas is sent to a photocatalytic device for deodorization and purification. Finally, the treated flue gas that meets the standards is discharged. The flue gas treatment process in this application is reasonable and effective, and the subsequent emissions also meet the standards.

[0016] Furthermore, the gas delivery pipe is equipped with a sampling structure, which includes a buffer chamber, a sampling bottle, and a return pipe. The bottom of the buffer chamber has an outlet that communicates with the gas delivery pipe, and the top of the buffer chamber has a sampling port. One end of the return pipe is connected to the side wall of the buffer chamber, and the other end is connected to the gas delivery pipe. The return pipe is also equipped with a vacuum pump.

[0017] By adopting the above technical solution, a buffer chamber is set up for sampling the purified flue gas, avoiding direct contact with the gas supply pipe and reducing the risk of flue gas leakage. After sampling, the gas in the buffer chamber can be drawn into the exhaust device by an exhaust fan, thus successfully completing the flue gas purification.

[0018] Furthermore, the buffer chamber is also equipped with a leak-proof component, which includes a rotating tooth, a linkage tooth, and a shielding cover. The rotating tooth is rotatably mounted at the sampling port and meshes with the linkage tooth. The rotating tooth is also coaxially mounted with the sampling port. The linkage tooth is rotatably mounted in the buffer chamber and is located on one side of the rotating tooth. The linkage tooth and the shielding cover are integrally mounted and rotate with the linkage tooth. The shielding cover is mounted above the air outlet.

[0019] Furthermore, the rotating tooth has a rotating notch arranged radially along the rotating tooth, and a rotating clip that engages with the rotating tooth extends from the mouth of the sampling bottle. A toggle clip extends from the rotating clip corresponding to the rotating notch.

[0020] By adopting the above technical solution, leakage prevention components are installed to prevent smoke leakage during sampling, thus ensuring the sampling operation.

[0021] In summary, the technical solution of this utility model has the following advantages:

[0022] 1. The exhaust gas purification equipment for recycled rubber production provided by this utility model adds exhaust gas purification equipment to the original waste gas treatment system to collect and purify the exhaust gas during the mixing tank production process. The exhaust gas treatment process is simplified compared to the waste gas treatment process, but sampling and testing are still required during subsequent emissions to ensure that they meet emission standards.

[0023] 2. The exhaust gas purification equipment for reclaimed rubber production provided by this utility model has a collection device that can collect and purify the exhaust gas in the working chamber from multiple angles and in all directions, and transport it to the subsequent processing equipment through pipelines to ensure the purification effect and improve the cleanliness and environmental friendliness of the reclaimed rubber production process.

[0024] 3. The exhaust gas purification equipment for recycled rubber production provided by this utility model has a sampling structure for sampling and testing of the exhaust gas and is equipped with anti-leakage components to ensure the safety of sampling sealing. Attached Figure Description

[0034] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0035] A purification device for escaping fumes from recycled rubber production, such as Figure 1As shown, the system includes multiple parallel chambers 1, a collection device 2, a filtration device 3, a washing device 4, a photocatalytic device 5, and an emission device 6. In this embodiment, two parallel chambers 1 are provided and share subsequent processing equipment. The collection device 2, filtration device 3, washing device 4, photocatalytic device 5, and emission device 6 are connected sequentially by pipelines. The collection device 2 is installed on the chamber 1 and includes a main collection pipe 21 and multiple sets of collection branch pipes 22. The main collection pipe 21 is connected to the filtration device 3. Each set of collection branch pipes 22 is connected at one end to a chamber 1 and at the other end to the main collection pipe 21. The number of collection branch pipes 22 corresponds to the number of chambers 1. A sampling structure 7 is provided between the photocatalytic device 5 and the emission device 6. Adding fugitive gas purification equipment to the existing waste gas treatment system allows for the collection and purification of fugitive gas generated during the mixing tank production process. Unlike production waste gas, fugitive gas has variable concentrations, low air volume, and uncertain dispersion patterns. Therefore, it needs to be collected from multiple angles and then treated uniformly. The fugitive gas treatment process is somewhat simplified compared to the waste gas treatment process, but sampling and testing are still required during subsequent emissions to ensure compliance with emission standards.

[0036] like Figure 1 and Figure 2 As shown, each set of collection pipes 22 includes two first collection pipes 221, two second collection pipes 222, and one sidewall collection pipe 223. Taking the left-hand chamber 1 as an example, the first collection pipes 221 are positioned near the center of the top left side of the chamber 1, while the second collection pipes 222 are positioned at the center of the front and rear ends of the top of the chamber 1. The diameter of the first collection pipes 221 is larger than that of the second collection pipes 222. The sidewall collection pipe 223 is located on the right side wall of the chamber 1. The multiple first collection pipes 221, second collection pipes 222, and sidewall collection pipes 223 ensure comprehensive collection of the escaping flue gas. The first collection pipes 221 are closer to the opening of the mixing tank, and therefore have a larger diameter than the second collection pipes 222.

[0037] like Figure 2 and Figure 3 As shown, a collection hood 224 is also provided at the connection between the side wall collection pipe 223 and the working chamber 1. The collection hood 224 is in the shape of a truncated quadrangular pyramid, and the area of ​​the side closer to the working chamber 1 is larger than the area of ​​the side farther away from the working chamber 1. The flue gas collected at the side wall collection pipe 223 is mostly dusty and relatively heavy, so the collection hood 224 is set up to gather and settle it.

[0038] A rectangular locking platform 11 is provided on the side wall of the workshop 1 corresponding to the collection cover 224. A docking platform 2241 extends from the contact point between the collection cover 224 and the locking platform 11. A sealing card 111 and an inlet card 112 extend from the locking platform 11. Both the sealing card 111 and the inlet card 112 are arranged around the circumference of the locking platform 11 and extend on the side of the locking platform 11 close to the docking platform 2241. The perimeter of the inlet card 112 is smaller than that of the sealing card 111. A docking groove 22411 is provided on the docking platform 2241 corresponding to the sealing card 111 and the inlet card 112. A dust collection net 12 is also locked on the side of the locking platform 11 away from the collection cover 224. The locking platform 11 and the docking platform 2241 are used to fix the collection cover 224 on the side wall of the working chamber 1. A double-layer locking structure is used - sealing card 111 and inlet card 112 to ensure that the collection cover 224 is firmly installed and to reduce the escape of flue gas from the working chamber 1. The dust collection net 12 reduces the dust entering the subsequent flue gas purification equipment.

[0039] like Figure 2 and Figure 4 As shown, each first collecting pipe 221 is fitted with a heat exchange tube sleeve 2212. The flue gas near the mouth of the mixing tank has a relatively high overall heat, which can be exchanged using the heat exchange structure 8, thereby realizing waste heat utilization. The heat exchange tube sleeve has a staggered connection inlet 22121 and a connection outlet 22122. The staggered connection inlet 22121 and connection outlet 22122 ensure that the refrigerant in the heat exchanger 81 can fully contact the outer wall of the first collecting pipe 221 to achieve sufficient heat exchange. Each set of collection pipes 22 is also connected to a heat exchange structure 8, which includes a heat exchanger 81, a refrigerant outlet pipe 82, and a refrigerant inlet pipe 83. The connection inlet 22121 is located above the connection outlet 22122. The connection inlet 22121 is connected to the refrigerant outlet pipe 82, and the connection outlet 22122 is connected to the refrigerant inlet pipe 83. Both the refrigerant outlet pipe 82 and the refrigerant inlet pipe 83 are connected to the heat exchanger 81. The heat exchanger 81 can be connected to other heating equipment to utilize the waste heat at the first collection pipe 221.

[0040] The first collecting pipe 221 is located inside the heat exchange tube sleeve 2212. A threaded pipe section 2211 extends integrally from the outer wall of the first collecting pipe 221. The threaded pipe section 2211 on the outer wall of the first collecting pipe 221 increases the contact area.

[0041] like Figure 1 and Figure 5As shown, the filtration device 3 is a multi-stage pre-filter, and the water washing device 4 includes a water washing tower 41, a demister layer 42, multiple filling layers 43, and multiple spray layers 44. The demister layer 42, multiple filling layers 43, and multiple spray layers 44 are all located inside the water washing tower 41. The demister layer 42 is located at the top inside the water washing tower 41. The filling layers 43 and spray layers 44 are correspondingly arranged and appear in pairs. The water washing device 4 also includes a spray pump 45 located outside the water washing tower 41 and connected to the spray layers 44. The photocatalytic device 5 is a UV photocatalytic device and is connected to the water washing device 4 through an exhaust pipe 51. The photocatalytic device 5 is connected to the emission device 6 through an air supply pipe 52. After the flue gas is collected, it is initially filtered and enters the subsequent devices. First, the water washing tower 41 performs alkaline washing and demisting, and then the flue gas is sent to the photocatalytic device 5 for deodorization and purification. Finally, the treated flue gas that meets the standards is emitted. The flue gas treatment process in this application is reasonable and effective, and the subsequent emissions also meet the standards.

[0042] like Figure 1 , Figure 5 and Figure 6 As shown, a sampling structure 7 is provided on the gas supply pipe 52. The sampling structure 7 includes a buffer chamber 71, a sampling bottle 72, and a return pipe 73. The bottom of the buffer chamber 71 has an outlet 711 that communicates with the gas supply pipe 52, and the top of the buffer chamber 71 has a sampling port 712. One end of the return pipe 73 is connected to the side wall of the buffer chamber 71, and the other end is connected to the gas supply pipe 52. A vacuum pump 731 is also provided on the return pipe 73. The buffer chamber 71 is used to sample the purified flue gas, avoiding direct contact with the gas supply pipe 52 and reducing the risk of flue gas leakage. After sampling, the gas in the buffer chamber 71 can be drawn into the exhaust device by the vacuum pump 731 to successfully complete the flue gas purification.

[0043] The buffer chamber 71 is also equipped with a leak-proof component 713, which includes a rotating tooth 7131, a linkage tooth 7132, and a shielding cover 7133. The rotating tooth 7131 is rotatably installed at the sampling port 712 and meshes with the linkage tooth 7132. The rotating tooth 7131 is also coaxially arranged with the sampling port 712. The linkage tooth 7132 is rotatably installed in the buffer chamber 71 and is located on one side of the rotating tooth 7131. In this embodiment, it is located on the right side of the rotating tooth 7131 and is rotatably installed in the buffer chamber 71 via a vertical rod. The linkage tooth 7132 is integrally set with the shielding cover 7133 and rotates with the linkage tooth 7132. The shielding cover 7133 is installed above the air outlet 711. The rotating tooth 7131 has a rotating notch 71311 along its radial direction. The sampling bottle 72 has a rotating clip 721 extending from its mouth to engage with the rotating tooth 7131. The rotating clip 721 has a toggle clip 7211 extending from its rotating notch 71311. The sampling port 712 also has a take-out port corresponding to the toggle clip 7211.

[0044] During sampling, the sampling bottle 72 is inserted into the sampling port 712. The rotating clip 721 engages with the rotating tooth 7131, and the actuating clip 7211 is embedded in the rotating notch 71311. Then, the sampling bottle 72 is rotated, which causes the rotating tooth 7131 to rotate and drive the linkage tooth 7132 to rotate. As a result, the cover 7133 at the bottom of the linkage tooth 7132 also rotates and exposes the air outlet 711 for sampling and gas collection. During the gas collection process, the presence of the actuating clip 7211 restricts the sampling bottle 72 to be vertical and cannot be pulled out directly, thus preventing the sampling bottle 72 from tipping over and leaking. After sampling is completed, the sampling bottle 72 is rotated to align the actuating clip 7211 with the outlet for easy removal of the sampling bottle 72. At this time, the rotating tooth 7131 also drives the linkage tooth 7132 to reset, covering the cover 7133 at the air outlet 711. The vacuum pump 731 can then be started to draw gas from the buffer chamber 71 and send it to the exhaust device.

[0045] The working principle and usage of the exhaust gas purification equipment for recycled rubber production are as follows: An exhaust gas purification device is added to the existing waste gas treatment system. The exhaust gas is collected by the first collection pipe 221, the second collection pipe 222, and the side wall collection pipe 223 and then collected into the main collection pipe 21. During the collection process, a heat exchange sleeve 2212 is also installed on the first collection pipe 221. The heat exchange sleeve 2212 is connected to the heat exchange structure 8 to realize the utilization of waste heat. The collected exhaust gas is first filtered and then sent to the water washing device 4 for water washing. After that, the treated exhaust gas is sent to the photocatalytic device 5. Finally, the qualified exhaust gas is discharged. Before the discharge, the exhaust gas condition is sampled and tested.
