Description
Technical Field
[0001] This utility model relates to the technical field of waste gas treatment devices, specifically a waste gas treatment device for a reaction vessel. Background Technology
[0002] In chemical production, reaction vessels often generate volatile organic compounds, dust, and other waste gases due to their high temperature, high pressure, and chemical reaction characteristics. If these waste gases are directly discharged into the external environment, they will cause pollution. In order to prevent the waste gases from entering the external environment, a waste gas treatment device needs to be connected to the outlet of the reaction vessel to filter and purify the waste gases. Existing waste gas treatment devices mostly use multiple filters of different precision on their inner side to intercept and filter different harmful substances in the waste gas. Some also install spray devices on the inner side to spray out treatment liquid for further purification of the waste gas. However, the filter screen inside this type of waste gas treatment device needs to be cleaned after long-term use. When cleaning, the waste gas treatment device needs to be opened. Since the space inside the waste gas treatment device is connected, the injection of waste gas needs to be stopped before cleaning can be carried out. This makes the device unable to work during cleaning, reducing its practicality. Therefore, a waste gas treatment device for a reaction vessel is proposed to address the above problems. Utility Model Content
[0003] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: A waste gas treatment device for a reaction vessel, comprising a filter barrel, a partition fixedly connected to the inner side of the filter barrel, a sealing frame fixedly connected to the inner side of the filter barrel, a sealing plate rotatably connected to the inner side of the filter barrel, the sealing plate and the sealing frame working together, a fixing screw threadedly connected to the inner side of the filter barrel, the fixing screw working together with the sealing plate, a filter screen fixedly connected to the outer side of the partition, and a pipe frame rotatably connected to the inner side of the partition, the pipe frame rotatably connected to the filter barrel, and connecting pipes connected to the inner sides of both the upper and lower ends of the pipe frame; this step, by setting the partition, sealing frame, sealing plate, fixing screw, pipe frame, and connecting pipes, enables… In use, first rotate the sealing plate to cover the opening on the side of the filter barrel, and make the inner arc surface of the sealing plate fit tightly against the sealing frame to achieve a tight seal. Then, screw the fixing screw into the inside of the opening at the upper end of the sealing plate to fix it. Then, rotate the pipe frame and connecting pipe to one side of the partition to filter the exhaust gas through the filter screen on one side of the partition. When cleaning, simply rotate the connecting pipe to the unused filter screen on the other side to discharge the exhaust gas into the other side of the partition and fix it. Then, rotate the sealing plate on the side to be cleaned until it no longer covers the opening on that side of the partition, making it easy to clean. This allows the filters on both sides to be used alternately, so that cleaning can be performed without interrupting filtration, improving the stability of the device.
[0005] Preferably, a connecting block is fixedly connected to one end of the tube frame, and a fixing block is fixedly connected to the upper side of the filter barrel. The fixing block and the connecting block are connected by bolts. This step, by setting the connecting block and the fixing block, allows the tube frame to rotate to one side of the partition after the connecting pipe rotates to the side of the partition. The bolts are then screwed into the fixing block and the inner side of the connecting block, which facilitates further restriction and fixation of the position of the tube frame, making it less likely for the tube frame to rotate again after rotation, thus improving the stability of the device.
[0006] Preferably, a sealing circular plate is fixedly connected to the outer side of the partition, and a spray pipe is fixedly connected to the inner side of the sealing circular plate. The spray pipe is fixedly connected to the pipe frame, and a fixed pipe is rotatably connected to one end of the spray pipe. The fixed pipe is fixedly connected to the filter barrel. This step, by setting the sealing circular plate, spray pipe, and fixed pipe, allows for the production of two sizes of partitions during manufacturing, depending on the complexity of the waste gas treatment. One type is a shorter partition, reserving space for the sealing circular plate. After this type of partition is installed inside the filter barrel, the upper and lower circular planes of the sealing circular plate will respectively adhere to the upper inner plane of the filter barrel and the upper side of the partition. In addition to using a partition to separate and seal the filter screens on both sides, another type of partition is one whose length is just enough to reach the inner height of the filter barrel. This partition can directly separate the filter screens on both sides. When dealing with more complex types of waste gas, by installing the sealing disc and spray pipe as shown in the figure, a pipe capable of delivering treatment liquid can be connected to the fixed pipe. The treatment liquid is poured into the fixed pipe and the inside of the spray pipe, allowing it to be sprayed from the spray pipe onto the inside of the filter barrel to contact the filter screen and the waste gas, thereby further spraying the waste gas. This makes the device suitable for treating more complex waste gas and improves its practicality.
[0007] Preferably, a sealing gasket is fixedly connected to the outer side of the filter screen, and a support plate is fixedly connected to the outer side of the sealing plate. The sealing gasket and the support plate work together. This step, by setting the sealing gasket and the support plate, ensures that after the sealing plate rotates to fit tightly against the filter screen and the sealing frame, the sealing gasket with a certain elasticity on the lower side of the filter screen fits tightly against the sealing plate, thereby further sealing the sealing plate and the filter screen. After sealing, the support plate is inserted under the sealing gasket to further support the end of the sealing gasket and the filter screen away from the filter screen, making the placement of the filter screen more stable and further improving the stability of the device.
[0008] Preferably, a metal plate is fixedly connected to the inner side of the sealing plate, and a magnetic plate is fixedly connected to the inner side of the sealing frame. The metal plate and the magnetic plate are used in conjunction. This step, by setting the metal plate and the magnetic plate, allows the magnetic plate to attract the metal plate when the sealing plate rotates to fit tightly against the sealing frame, thereby further restricting and fixing the position of the sealing plate, making its shielding of the filter barrel more stable, and improving the stability of the device in use.
[0009] Preferably, a mounting plate is fixedly connected to the outside of the filter barrel, and the surface of the mounting plate is provided with a mounting groove. This step, by setting up the mounting plate and the mounting groove, makes it easier to install and fix the device by screwing the bolts into the mounting groove and the mounting location before the device is used, thereby improving the convenience of device installation.
[0010] The advantages of this utility model are: 1. This utility model, by setting up a partition, sealing frame, sealing plate, fixing screw, pipe frame and connecting pipe, allows for the following operation: First, rotate the sealing plate to cover the opening on the side of the filter barrel, and make the inner arc surface of the sealing plate fit tightly against the sealing frame to achieve a tight seal. Then, screw the fixing screw into the opening at the upper end of the sealing plate to fix it. Next, rotate the pipe frame and connecting pipe to one side of the partition to filter the exhaust gas through the filter screen on one side of the partition. For cleaning, simply rotate the connecting pipe to the unused filter screen on the other side to discharge the exhaust gas into the other side of the partition and fix it. Then, rotate the sealing plate on the side to be cleaned to no longer cover the opening on that side of the partition, making cleaning easier. This allows the filters on both sides to be used alternately, so that cleaning can be performed without interrupting filtration, thus improving the stability of the device. 2. By setting up connecting blocks and fixing blocks, this utility model allows the pipe frame to rotate to one side of the partition after the pipe frame drives the connecting pipe to rotate. Then, bolts are screwed into the fixing block and the inner side of the connecting block on one side, which facilitates further restriction and fixation of the position of the pipe frame. This makes it difficult for the pipe frame to rotate again after rotation, thus improving the stability of the device. Attached Figure Description

Detailed Implementation
[0014] 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 scope of protection of the present utility model.
[0015] Specific implementation examples are given below.
[0016] Please see Figures 1 to 5 As shown, a waste gas treatment device for a reactor includes a filter barrel 1. A partition 2 is fixedly connected to the inner side of the filter barrel 1. A sealing frame 3 is fixedly connected to the inner side of the filter barrel 1. A sealing plate 4 is rotatably connected to the inner side of the filter barrel 1. The sealing plate 4 and the sealing frame 3 cooperate with each other. A fixing screw 5 is threadedly connected to the inner side of the filter barrel 1. The fixing screw 5 and the sealing plate 4 cooperate with each other. A filter screen 6 is fixedly connected to the outer side of the partition 2. A pipe frame 7 is rotatably connected to the inner side of the partition 2. The pipe frame 7 is rotatably connected to the filter barrel 1. Connecting pipes 8 are connected to the inner sides of both the upper and lower ends of the pipe frame 7. This step involves setting up the partition 2, sealing frame 3, sealing plate 4, fixing screw 5, pipe frame 7, and connecting pipe 8. In use, the sealing plate 4 is first... Rotate the filter to block the opening on the side of the filter barrel 1, and make the inner arc surface of the sealing plate 4 fit tightly against the sealing frame 3 to achieve a tight seal. Then screw the fixing screw 5 into the inside of the opening at one end of the upper side of the sealing plate 4 to fix it. Then rotate the pipe frame 7 and the connecting pipe 8 to one side of the partition 2, so that the exhaust gas is filtered through the filter screen 6 on one side of the partition 2. When cleaning, simply rotate the connecting pipe 8 to the side of the unused filter screen 6 to discharge the exhaust gas into the other side of the partition 2 and fix it. Then rotate the sealing plate 4 on the side to be cleaned until it no longer blocks the opening on one side of the partition 2, so as to facilitate cleaning. The filter screens 6 on both sides can be used alternately, so that cleaning can be carried out without interrupting the filtration, which improves the stability of the device.
[0017] Furthermore, such as Figure 1 As shown, a connecting block 9 is fixedly connected to one end of the tube frame 7, and a fixing block 10 is fixedly connected to the upper side of the filter barrel 1. The fixing block 10 and the connecting block 9 are connected by bolts. This step, by setting the connecting block 9 and the fixing block 10, allows the tube frame 7 to rotate the connecting pipe 8 to one side of the partition plate 2, and then the bolts are screwed into the fixing block 10 and the inner side of the connecting block 9. This facilitates further restriction and fixation of the position of the tube frame 7, making it less likely for the tube frame 7 to rotate again after rotation, thus improving the stability of the device.
[0018] Furthermore, such as Figure 2 , Figure 3 and Figure 5As shown, a sealing circular plate 11 is fixedly connected to the outer side of the partition 2, and a spray pipe 12 is fixedly connected to the inner side of the sealing circular plate 11. The spray pipe 12 is fixedly connected to the pipe frame 7, and a fixed pipe 13 is rotatably connected to one end of the spray pipe 12. The fixed pipe 13 is fixedly connected to the filter barrel 1. This step, by setting the sealing circular plate 11, spray pipe 12, and fixed pipe 13, allows for the production of two sizes of partition 2 according to the complexity of waste gas treatment during actual production. One type is a shorter partition 2 that leaves space for placing the sealing circular plate 11. After this type of partition 2 is installed inside the filter barrel 1, the upper and lower circular planes of the sealing circular plate 11 will respectively adhere to the upper inner plane of the filter barrel 1 and the partition. On the upper side of plate 2, a partition plate 2 is used to separate and seal the filter screens 6 on both sides. Another type is a partition plate 2 with a length just enough to reach the inner height of the filter barrel 1. This partition plate 2 can directly separate the filter screens 6 on both sides. When more complex types of waste gas need to be treated, the sealing circular plate 11 and the spray pipe 12 are installed as shown in the figure, so that the fixed pipe 13 can be connected to a pipe that can transport the treatment liquid. The treatment liquid is poured into the fixed pipe 13 and the inside of the spray pipe 12, so that the treatment liquid can be sprayed from the spray pipe 12 to the inside of the filter barrel 1 to contact the filter screens 6 and the waste gas, thereby further spraying the waste gas. This makes the device suitable for treating more complex waste gases and improves the practicality of the device.
[0019] Furthermore, such as Figure 2 and Figure 4 As shown, a sealing gasket 14 is fixedly connected to the outer side of the filter screen 6, and a support plate 15 is fixedly connected to the outer side of the sealing plate 4. The sealing gasket 14 and the support plate 15 work together. This step, by setting the sealing gasket 14 and the support plate 15, ensures that after the sealing plate 4 rotates to fit tightly against the filter screen 6 and the sealing frame 3, the sealing gasket 14, which has a certain elasticity, fits tightly against the sealing plate 4 on the lower side of the filter screen 6, thereby further sealing the space between the sealing plate 4 and the filter screen 6. After sealing, the support plate 15 is inserted under the sealing gasket 14 to further support the end of the sealing gasket 14 and the filter screen 6 away from the filter screen 6, making the placement of the filter screen 6 more stable and further improving the stability of the device.
[0020] Furthermore, such as Figure 2 and Figure 4 As shown, a metal plate 16 is fixedly connected to the inner side of the sealing plate 4, and a magnetic plate 17 is fixedly connected to the inner side of the sealing frame 3. The metal plate 16 and the magnetic plate 17 work together. By setting the metal plate 16 and the magnetic plate 17, when the sealing plate 4 rotates to be close to the sealing frame 3, one side of the magnetic plate 17 will attract the metal plate 16, thereby further restricting and fixing the position of the sealing plate 4, making its shielding of the filter barrel 1 more stable, and improving the stability of the device.
[0021] Furthermore, such as Figure 1 As shown, an installation plate 18 is fixedly connected to the outside of the filter barrel 1, and an installation groove 19 is provided on the surface of the installation plate 18. This step, by setting the installation plate 18 and the installation groove 19, makes it easier to install and fix the device by screwing the bolts into the installation groove 19 and the installation location before the device is used, thereby improving the convenience of device installation.
[0022] Working principle: In use, first rotate the sealing plate 4 to block the side opening of the filter bucket 1, and make the inner arc surface of the sealing plate 4 fit tightly against the sealing frame 3 to achieve a tight seal. Then, screw the fixing screw 5 into the inside of the opening at one end of the upper side of the sealing plate 4 to fix it. Next, rotate the pipe frame 7 and the connecting pipe 8 to one side of the partition 2, so that the pipe frame 7 simultaneously moves the sealing circular plate 11 and the spray pipe 12 to one side of the partition 2. Screw the bolts into the inside of the connecting block 9 and the fixing block 10 to restrict and fix the position of the pipe frame 7, so that the connecting pipe 8 can fix the exhaust gas into the filter screen 6 on one side of the partition 2 for exhaust gas treatment. The system filters the waste gas and injects a treatment liquid into the inside of the fixed pipe 13, allowing the liquid to pass through the pipe and enter the inside of the spray pipe 12. Finally, the liquid is discharged through the lower opening of the spray pipe 12, facilitating contact and reaction between the treatment liquid and the waste gas to purify it. During cleaning, simply rotate the connecting pipe 8 to the unused filter screen 6 on the other side to discharge the waste gas into the other side of the partition 2 for fixing. Then, rotate the sealing plate 4 on the side to be cleaned until it no longer blocks the opening on one side of the partition 2, making cleaning easier. This allows the filter screens 6 on both sides to be used alternately, thus enabling cleaning without interrupting the filtration process.
