Description

Technical Field

[0001] This utility model relates to the technical field of industrial waste gas purification equipment, specifically a gas purification device for a reaction vessel. Background Technology

[0002] In chemical synthesis processes, reaction vessels are often used to carry out esterification, polymerization, condensation, and other reactions under high temperature and high pressure conditions. After a process is completed, high-temperature waste gas needs to be discharged from the reaction vessel, which is often referred to as reaction vessel venting waste gas. Since the emission of reaction vessel venting waste gas is intermittent, some purification equipment opens a cavity on the inside of the purification chamber and injects water into the cavity. The water cools the inner wall of the purification chamber, thereby cooling and liquefying the waste gas, which then flows down to contact the activated carbon mesh for filtration. During use, the condensate will not come into contact with the waste gas, making it less likely to cause secondary pollution.

[0003] However, when the exhaust gas condenses on the inner wall of the purification tank, it needs to accumulate to a certain volume before flowing down. This means that even after the wastewater is liquefied, some of it will still adhere to the purification tank and cannot flow down to contact the activated carbon mesh for purification and filtration, making the purification process take longer and reducing the practicality of the device. Therefore, a gas purification device for a reaction vessel is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A gas purification device for a reaction vessel, comprising a reaction vessel, an exhaust valve connected to the outside of the reaction vessel, a purification chamber connected to the outside of the exhaust valve, a drive motor fixedly connected to the outside of the purification chamber, a lifting screw fixedly connected to the output end of the drive motor, a lifting plate threadedly connected to the outside of the lifting screw, a sliding connection between the lifting plate and the purification chamber, a first scraper fixedly connected to the outside of the lifting plate, an activated carbon mesh slidably connected to the inside of the purification chamber, a sealing plate slidably connected to the outside of the activated carbon mesh, a fixing screw rotatably connected to the inside of the sealing plate, a threaded connection between the fixing screw and the purification chamber, and a water tank opened inside the purification chamber. A water pipe connects to the inside of the water tank. This step involves setting up a lifting screw, a first scraper pad, an activated carbon mesh, and a water tank. During use, the waste gas generated by the reactor is injected into the inside of the purification chamber through the exhaust valve, and then water is injected through one side of the water pipe. The water flow cools the inner wall of the purification chamber, causing the waste gas to condense and liquefy on the inner wall. After the waste gas has condensed, the lifting screw is driven by the drive motor to rotate, which in turn moves the lifting plate and the first scraper pad. The first scraper pad adheres tightly to the inner wall of the purification chamber, causing the wastewater liquefied from the waste gas to accumulate and flow down quickly. It then contacts the activated carbon mesh for purification and filtration. This prevents the wastewater from adhering to the inner wall of the purification chamber for a long time and prevents it from falling down, thus improving the stability of the device.

[0006] Preferably, a baffle is fixedly connected to the outside of the lifting screw, and a second scraper is fixedly connected to the outside of the baffle. The second scraper works in conjunction with the lifting plate. By setting the baffle and the second scraper, after the lifting plate moves to its maximum position, the baffle blocks and restricts it, making it difficult for the lifting plate to detach from the lifting screw. After the lifting plate moves down close to the second scraper, the lifting screw drives the baffle and the second scraper to rotate, and the second scraper further scrapes off the wastewater condensed on the lower side of the lifting plate, making it difficult for wastewater to adhere to the lower side of the lifting plate, thus further improving the stability of the purification process.

[0007] Preferably, a positioning block is slidably connected to the inner side of the activated carbon mesh, and the positioning block is fixedly connected to the purification box. This step, by setting the positioning block, allows the activated carbon mesh to be inserted into the purification box, and the positioning block can further restrict and support its position, making its installation more stable and improving the stability of the device.

[0008] Preferably, a synchronous gear is fixedly connected to the outside of the fixing screw, and a toothed plate meshes with the outside of the synchronous gear. The toothed plate and the sealing plate are slidably connected. This step, by setting the synchronous gear and the toothed plate, ensures that when the fixing screw on one side rotates, it will drive the synchronous gear on the other side to rotate. This allows the fixing screws on both sides to be screwed into or out of the purification box at the same time, making the installation and removal of the sealing plate more convenient, and thus making the replacement of the activated carbon mesh more convenient, thereby improving the ease of use of the device.

[0009] Preferably, a limiting plate is fixedly connected to the outside of the sealing plate. The limiting plate and the toothed plate work together. By setting the limiting plate, the toothed plate is blocked after it moves to the extreme position, making it difficult for the toothed plate to separate from the sealing plate, thus improving the stability of the device.

[0010] Preferably, slots are provided on both the surface of the toothed plate and the inner side of the sealing plate, and a rod is slidably connected to the inner side of the slot. This step, by setting the slots and the rod, allows the toothed plate to be fixed in position by inserting the rod into the inner side of the slot when it does not need to be moved. This further fixes the fixing screw, making the installation of the sealing plate more stable and improving the stability of the device.

[0011] The advantages of this utility model are:

[0012] 1. This utility model, by setting up a lifting screw, a first scraper pad, an activated carbon mesh, and a water tank, allows the waste gas generated by the reactor to be injected into the inner side of the purification chamber through an exhaust valve during use. Then, water is injected through a water pipe on one side, which cools the inner wall of the purification chamber, causing the waste gas to be condensed and liquefied on the inner wall of the purification chamber. After the waste gas has been condensed, the lifting screw is driven by a drive motor to rotate, which in turn moves the lifting plate and the first scraper pad. The first scraper pad adheres tightly to the inner wall of the purification chamber, causing the wastewater generated by the liquefied waste gas to accumulate and flow down quickly. Then, it comes into contact with the activated carbon mesh for purification and filtration. This makes it less likely for the wastewater generated by the liquefied waste gas to adhere to the inner wall of the purification chamber for a long time and not fall down, thus improving the stability of the device.

[0013] 2. By setting up a baffle and a second scraper pad, the baffle restricts the lifting plate after it moves to its maximum position, making it less likely for the lifting plate to detach from the lifting screw. After the lifting plate moves down close to the second scraper pad, the lifting screw drives the baffle and the second scraper pad to rotate, and the second scraper pad further scrapes off the wastewater condensed on the lower side of the lifting plate, making it less likely for wastewater to adhere to the lower side of the lifting plate, thus further improving the stability of the purification process.

Detailed Implementation

[0021] 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.

[0022] Specific implementation examples are given below.

[0023] Please see Figure 1-5As shown, a gas purification device for a reaction vessel includes a reaction vessel 1. An exhaust valve 2 is connected to the outside of the reaction vessel 1. A purification chamber 3 is connected to the outside of the exhaust valve 2. A drive motor 4 is fixedly connected to the outside of the purification chamber 3. A lifting screw 5 is fixedly connected to the output end of the drive motor 4. A lifting plate 6 is threadedly connected to the outside of the lifting screw 5. The lifting plate 6 and the purification chamber 3 are slidably connected. A first scraper pad 7 is fixedly connected to the outside of the lifting plate 6. An activated carbon mesh 8 is slidably connected to the inside of the purification chamber 3. A sealing plate 9 is slidably connected to the outside of the activated carbon mesh 8. A fixing screw 10 is rotatably connected to the inside of the sealing plate 9. The fixing screw 10 is threadedly connected to the purification chamber 3. A water tank 11 is opened inside the purification chamber 3, and a water pipe is connected to the inside of the water tank 11. 12. This step involves setting up a lifting screw 5, a first scraper pad 7, an activated carbon mesh 8, and a water tank 11. During use, the waste gas generated by the reactor 1 is injected into the inner side of the purification tank 3 through the exhaust valve 2, and then water is injected through a water pipe 12 on one side. The water flow cools the inner wall of the purification tank 3, causing the waste gas to be condensed and liquefied on the inner wall of the purification tank 3. After the waste gas has condensed, the lifting screw 5 is rotated by the drive motor 4, which in turn moves the lifting plate 6 and the first scraper pad 7. The first scraper pad 7 adheres tightly to the inner wall of the purification tank 3, causing the wastewater generated by the liquefied waste gas to accumulate and flow down quickly. Then, it comes into contact with the activated carbon mesh 8 for purification and filtration. This prevents the wastewater generated by the liquefied waste gas from adhering to the inner wall of the purification tank 3 for a long time and from falling down, thus improving the stability of the device.

[0024] Furthermore, such as Figure 1 As shown, a baffle 13 is fixedly connected to the outside of the lifting screw 5, and a second scraper pad 14 is fixedly connected to the outside of the baffle 13. The second scraper pad 14 works in conjunction with the lifting plate 6. In this step, by setting the baffle 13 and the second scraper pad 14, after the lifting plate 6 moves to its maximum position, the baffle 13 blocks and restricts it, making it difficult for the lifting plate 6 to fall off the lifting screw 5. After the lifting plate 6 moves down close to the second scraper pad 14, the lifting screw 5 drives the baffle 13 and the second scraper pad 14 to rotate, and the second scraper pad 14 further scrapes off the wastewater condensed on the lower side of the lifting plate 6, thereby making it difficult for wastewater to adhere to the lower side of the lifting plate 6, and further improving the stability of the purification device.

[0025] Furthermore, such as Figure 1 As shown, a positioning block 15 is slidably connected to the inner side of the activated carbon mesh 8. The positioning block 15 is fixedly connected to the purification box 3. By setting the positioning block 15, the activated carbon mesh 8 can be further restricted and supported in position after being inserted into the purification box 3, making its installation more stable and improving the stability of the device.

[0026] Furthermore, such as Figure 4As shown, a synchronous gear 16 is fixedly connected to the outside of the fixing screw 10, and a toothed plate 17 meshes with the outside of the synchronous gear 16. The toothed plate 17 and the sealing plate 9 are slidably connected. By setting the synchronous gear 16 and the toothed plate 17, when the fixing screw 10 on one side rotates, it will drive the synchronous gear 16 on the other side to rotate. This allows the fixing screws 10 on both sides to be screwed into or out of the purification box 3 at the same time, making the disassembly and assembly of the sealing plate 9 more convenient, and thus making the replacement of the activated carbon mesh 8 more convenient, improving the ease of use of the device.

[0027] Furthermore, such as Figure 4 As shown, a limiting plate 18 is fixedly connected to the outer side of the sealing plate 9. The limiting plate 18 and the toothed plate 17 are used together. By setting the limiting plate 18, after the toothed plate 17 moves to the extreme position, the limiting plate 18 blocks it, making it difficult for the toothed plate 17 to separate from the sealing plate 9, thus improving the stability of the device.

[0028] Furthermore, such as Figure 4 As shown, slots 19 are provided on the surface of the toothed plate 17 and the inner side of the sealing plate 9. A rod 20 is slidably connected to the inner side of the slot 19. By setting the slot 19 and the rod 20, when the toothed plate 17 does not need to be moved, the rod 20 can be inserted into the inner side of the slot 19 to fix the position of the toothed plate 17, thereby further fixing the fixing screw 10, making the installation of the sealing plate 9 more stable and improving the stability of the device.

[0029] Working principle: During use, the waste gas generated by the reactor 1 is injected into the inner side of the purification tank 3 through the exhaust valve 2, and then water is injected through the water pipe 12 on one side. The water flow cools the inner wall of the purification tank 3, causing the waste gas to be condensed and liquefied on the inner wall of the purification tank 3. After the waste gas is condensed, the drive motor 4 drives the lifting screw 5 to rotate, which in turn drives the lifting plate 6 and the first scraper pad 7 to move. The first scraper pad 7 is pressed against the inner wall of the purification tank 3, causing the wastewater liquefied from the waste gas to accumulate and flow down quickly. Then it comes into contact with the activated carbon mesh 8 for purification and filtration. When the lifting plate 6 moves close to the second scraper pad 14, the lifting screw 5 drives the second scraper pad 14 to rotate, thereby scraping off the wastewater condensed on the lower side of the lifting plate 6. Then it is purified and filtered by the activated carbon mesh 8.
