Description

Technical Field

[0001] This invention relates to the field of waste gas purification technology, and in particular to a waste gas purification and recycling device applied to a magnetically driven reactor. Background Technology

[0002] In chemical synthesis reactions, reaction vessels are often used to carry out esterification, polymerization, condensation, and other reactions under high temperature and high pressure conditions. After one process step is completed, high-temperature waste gas needs to be discharged from the reaction vessel, often referred to as reaction vessel venting gas. Because reaction vessel venting gas has a fast release rate, high concentration, and intermittent emission, it makes the purification of subsequent waste gas very difficult.

[0003] Chinese patent application CN201621337669.0 discloses a waste gas purification mechanism, including a reaction vessel and an outlet pipe connected to the top end cover of the reaction vessel. The end of the outlet pipe is connected to a cooling box, and the bottom of the cooling box is connected to a clean gas box via a connecting pipe. The bottom of the clean gas box is connected to an exhaust pipe. The cooling box contains multiple layers of cooling plates, with cooling cavities formed between adjacent cooling plates. Through holes are provided on the cooling plates. The outlet pipe is connected to the top of the cooling box. An inclined guide plate is provided at the bottom of the cooling box, and a water valve is connected to one side of the inclined guide plate. This structure allows for cleaning or replacement of the inner tank by setting a cover plate on top of the clean gas phase and opening the cover plate. Since the filter plate filters and isolates a large number of air bubbles and droplets during waste gas purification, it needs to be cleaned or replaced regularly to avoid affecting the filtration effect. However, manual cleaning is not only cumbersome but also has limitations in cleaning efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a waste gas purification and recycling device for magnetically driven reactors, aiming to solve the above-mentioned technical problems.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A waste gas purification and recycling device for a magnetically driven reaction vessel includes a vessel body. A purification box is fixedly installed on one side of the vessel body. The upper end of the vessel body is connected to the purification box via an exhaust pipe. A condenser and an exhaust valve are respectively installed on the exhaust pipe. The exhaust valve is located between the condenser and the vessel body. One side of the purification box is connected to one end of an activated carbon adsorption box via a pipeline. The other end of the activated carbon adsorption box is connected to a gas detector via a pipeline. The outlet end of the gas detector is connected to an outlet pipe. The other outlet end of the gas detector is connected to a return pipe. The return pipe is connected to the exhaust pipe. A transmission component is installed on the exhaust pipe. A movable filter plate and a fixed filter plate are arranged sequentially from top to bottom inside the purification box.

[0007] The transmission assembly includes a pair of side plates symmetrically arranged on both sides of the exhaust pipe. The inner walls of the side plates are provided with longitudinal toothed grooves. Extended outer shells are provided on both sides of the exhaust pipe. Rotary impellers are rotatably installed inside the extended outer shells. Synchronous gears are fixedly sleeved at both ends of the impeller shafts, meshing with the longitudinal toothed grooves. A connecting rod is fixedly connected to the bottom of the side plates. The bottom end of the connecting rod slides through the top of the purification chamber and the movable filter plate. A support block extends from the inner wall of the connecting rod and is located below the movable filter plate. A pair of mounting plates are abutted against the surface of the fixed filter plate. Cleaning brushes are arranged at the bottom of the mounting plates. The bottom of the connecting rod rotatably engages with one end of a connecting rod, and the other end of the connecting rod rotatably connects to the top of the corresponding mounting plate. An inlet pipe is connected to one side of the purification chamber, and a drain pipe is connected to the bottom of the purification chamber. The side plates control the opening and closing of the inlet pipe during the exhaust gas emission process.

[0008] As a further embodiment of the present invention: support plates are provided on both sides of the exhaust pipe, the support plates are located above the side plates, a guide rod is fixedly connected to the top of the side plates, the top of the guide rod slides through the support plate, and a return spring is provided between the bottom of the support plate and the side plates.

[0009] As a further aspect of the present invention: the movable filter plate has through-grooves on both sides for the connecting rod to pass through, and the width of the supporting block is much larger than the gap between the connecting rod and the through-grooves.

[0010] As a further embodiment of the present invention: a blocking seat is fixedly installed on the inner wall of the purification box, and top rods are distributed at the four corners of the upper end of the movable filter plate. The sliding rods of the top rods pass through the corresponding blocking seats and are fixedly connected to the baffles. A pressure sensor is installed at the upper end of the blocking seat, and a pressure spring is installed between the bottom of the baffle and the pressure sensor.

[0011] As a further aspect of the present invention: a control valve is provided on the inlet pipe, the pressure sensor is communicatively connected to the control valve, a spray pipe is connected to the outlet of the inlet pipe, the spray pipe is fixedly installed on the inner wall of the purification box, and a plurality of spray nozzles are arranged at equal intervals on the spray pipe, with the spray nozzles tilted toward the movable filter plate.

[0012] As a further embodiment of the present invention: the spray pipe is arranged around the inner wall of the purification box, and the spray pipe is located above the movable filter plate.

[0013] As a further embodiment of the present invention: a mounting base is fixedly provided on the inner wall of the purification box, the fixed filter plate is fixedly provided in the mounting base, and slide rails are fixedly provided on the front and rear sides of the inner wall of the purification box, with both ends of the mounting plate slidingly engaged with the slide rails.

[0014] As a further aspect of the present invention: a waterproof and breathable valve is provided on the connecting pipe between the purification box and the activated carbon adsorption box.

[0015] As a further aspect of the present invention: a sliding sealing ring is provided between the connecting rod and the top of the purification box.

[0016] The beneficial effects of this invention are:

[0017] (1) By setting up a transmission component, when exhaust gas is discharged, the connecting rod drives the support block to rise upward, and the support block will support the movable filter plate and move upward synchronously. At the same time, the connecting rod will drive the mounting plate to slide to both sides of the fixed filter plate through the connecting rod. The movable filter plate and the fixed filter plate will perform normal filtration and blocking functions for the exhaust gas. When the exhaust gas is stopped, the side plate moves downward to reset, and the support block will no longer support the movable filter plate. The movable filter plate moves downward. At this time, the liquid inlet pipe is opened, and the liquid inlet pipe will spray cleaning liquid onto the movable filter plate, thereby spraying and rinsing the movable filter plate. With the up and down vibration of the movable filter plate, the filtered air bubbles can be quickly vibrated and removed. At the same time, as the connecting rod resets and moves, the mounting plate will slide in the opposite direction on the surface of the fixed filter plate through the connecting rod, and the fixed filter plate will be cleaned by the cleaning brush. Thus, the filter plate can be automatically cleaned within the time interval of exhaust gas discharge in the vessel. There is no need to disassemble the purification box. The cleaning efficiency is high and the cleaning effect is effectively improved.

[0018] (2) The pressure value is detected by the pressure sensor. The change in the pressure value between the two times is the weight change of the movable filter plate before and after filtration. This is used to accurately detect the weight of the bubble droplets filtered and isolated on the movable filter plate. When the pressure change exceeds the specified threshold, the pressure sensor will send a signal to open the control valve. When enough bubble droplets accumulate on the movable filter plate, it can automatically perform spray cleaning. It is also ensured that each spraying process is carried out during the stage of stopping the exhaust, which ensures the dryness of the exhaust gas during purification and avoids affecting the subsequent activated carbon adsorption process.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1 and Figure 2 As shown, the present invention is a waste gas purification and recycling device applied to a magnetically driven reaction vessel, including a vessel body 1. A purification box 3 is fixedly installed on one side of the vessel body 1. The upper end of the vessel body 1 is connected to the purification box 3 through an exhaust pipe 2. A condenser 202 and an exhaust valve 201 are respectively installed on the exhaust pipe 2. The exhaust valve 201 is located between the condenser 202 and the vessel body 1. One side of the purification box 3 is connected to one end of an activated carbon adsorption box 4 through a pipeline. The other end of the activated carbon adsorption box 4 is connected to a gas detector 5 through a pipeline. The gas detector 5 has an outlet pipe 501 connected to its outlet end and a return pipe 502 connected to its other outlet end. The return pipe 502 is connected to the exhaust pipe 2. A transmission component 6 is installed on the exhaust pipe 2. A movable filter plate 7 and a fixed filter plate 8 are arranged sequentially from top to bottom inside the purification box 3.

[0029] Specifically, when the vessel 1 discharges vented waste gas, the exhaust valve 201 is first opened, and the vented waste gas passes through the exhaust pipe 2 and the condenser 202, where the organic matter in the waste gas is condensed into liquid and separated. The condensed waste gas continues to flow into the purification box 3, where the movable filter plate 7 and the fixed filter plate 8 are used to filter the oily air bubbles in the gas. The air bubbles are blocked on the filter plates. The filtered waste gas continues to flow through the pipeline into the activated carbon adsorption box 4 for adsorption treatment. Then the gas flows into the gas detector 5. When the gas quality meets the emission standards, the gas will be discharged and collected through the outlet pipe 501 for recycling. When the gas quality does not meet the emission standards, the gas will flow through the return pipe 502 into the exhaust pipe 2 for filtration and adsorption again until the emission standards are met.

[0030] like Figure 3 , Figure 4 and Figure 6 As shown, the transmission assembly 6 includes a pair of side plates 601 symmetrically arranged on both sides of the exhaust pipe 2. The inner walls of the side plates 601 are provided with longitudinal toothed grooves 604. Extended outer shells 203 are provided on both sides of the exhaust pipe 2. Rotary impellers 204 are rotatably installed inside the extended outer shells 203. Synchronous gears 205 are fixedly sleeved at both ends of the axle of the rotating impellers 204, meshing with the longitudinal toothed grooves 604. A connecting rod 602 is fixedly connected to the bottom of the side plates 601. The bottom end of the connecting rod 602 slides through the top of the purification box 3 and the movable filter plate 7. The connecting rod 602... A support block 603 extends from the side wall and is positioned below the movable filter plate 7. A pair of mounting plates 608 are attached to the surface of the fixed filter plate 8. Cleaning brushes 609 are arranged at the bottom of the mounting plates 608. The bottom of the connecting rod 602 is rotatably engaged with one end of the connecting rod 607, and the other end of the connecting rod 607 is rotatably connected to the top of the corresponding mounting plate 608. An inlet pipe 301 is connected to one side of the purification box 3, and a drain pipe 302 is connected to the bottom of the purification box 3. The side plate 601 controls the opening and closing of the inlet pipe 301 during the exhaust gas discharge process.

[0031] Specifically, by setting the transmission component 6, when exhaust gas is discharged, the gas flowing in the exhaust pipe 2 will drive the rotating impeller 204 to rotate, and the rotating impeller 204 will drive the synchronous gear 205 to rotate. Since the synchronous gear 205 meshes with the longitudinal tooth groove 604, the synchronous gear 205 will drive the side plate 601 to move upward, thereby causing the connecting rod 602 to drive the support block 603 to rise upward. The support block 603 will support the movable filter plate 7 and move upward synchronously. At this time, the control liquid inlet pipe 301 is closed, and at the same time, the connecting rod 602 will drive the mounting plate 608 to slide to both sides of the fixed filter plate 8 through the connecting rod 607, so that the movable filter plate 7 and the fixed filter plate 8 can normally achieve the filtration and blocking function. When exhaust gas emission stops, the side plate 601 moves downward to reset, and the support block 603 will no longer support the movable filter plate 7. The movable filter plate 7 moves downward, and at this time, the control liquid inlet pipe 301 is opened. The liquid inlet pipe 301 will spray cleaning solution onto the movable filter plate 7, thereby spraying and rinsing the movable filter plate 7. With the up and down vibration of the movable filter plate 7, the filtered air bubbles can be quickly vibrated and detached. At the same time, as the connecting rod 602 resets and moves, the mounting plate 608 will also slide in the opposite direction on the surface of the fixed filter plate 8 through the connecting rod 607, and use the cleaning brush 609 to wash and clean the fixed filter plate 8. Thus, the filter plate can be automatically cleaned within the time interval of exhaust gas emission from the vessel 1 without disassembling the purification box 3. The cleaning efficiency is high and the cleaning effect is effectively improved.

[0032] like Figure 3 As shown, support plates 206 are extended on both sides of the exhaust pipe 2. The support plates 206 are located above the side plate 601. A guide rod 605 is fixedly connected to the top of the side plate 601. The top of the guide rod 605 slides through the support plate 206. A return spring 606 is provided between the bottom of the support plate 206 and the side plate 601.

[0033] Specifically, during exhaust gas discharge, the rotating impeller 204 rotates, driving the synchronous gear 205 to rotate, which in turn moves the side plate 601 upward. At this time, the side plate 601 drives the guide rod 605 to move upward synchronously, while the return spring 606 is compressed and deformed. When exhaust gas discharge stops, under the elastic force of the return spring 606, the side plate 601 will automatically move downward to its original position, facilitating subsequent spraying and scraping processes. During this process, the guide rod 605 acts as a limit and guide for the up-and-down movement of the side plate 601, ensuring the stability of its movement.

[0034] like Figure 4 and Figure 5 As shown, the movable filter plate 7 has clearance grooves 701 through its two side edges for the connecting rod 602 to pass through, and the width of the support block 603 is much larger than the gap between the connecting rod 602 and the clearance grooves 701.

[0035] Specifically, by setting the clearance groove 701, the connecting rod 602 can pass smoothly through the movable filter plate 7. When the connecting rod 602 rises, the support block 603 can support the movable filter plate 7 from the bottom and raise it synchronously. When the connecting rod 602 falls, the support block 603 falls synchronously until it no longer supports the movable filter plate 7.

[0036] like Figure 3 and Figure 4 As shown, a baffle seat 305 is fixedly installed on the inner wall of the purification box 3. A top rod 702 is distributed at the four corners of the upper end of the movable filter plate 7. The sliding rod of the top rod 702 passes through the corresponding baffle seat 305 and is fixedly connected to the baffle 703. A pressure sensor 3051 is installed at the upper end of the baffle seat 305. A pressure spring 704 is installed between the bottom of the baffle 703 and the pressure sensor 3051.

[0037] Furthermore, a control valve 3011 is provided on the inlet pipe 301, and a pressure sensor 3051 is communicatively connected to the control valve 3011. A spray pipe 3012 is connected to the outlet of the inlet pipe 301. The spray pipe 3012 is fixedly installed on the inner wall of the purification box 3. Several nozzles 3013 are arranged at equal intervals on the spray pipe 3012, and the nozzles 3013 are tilted towards the movable filter plate 7.

[0038] Specifically, by setting up the blocking seat 305 and the inlet pipe 301, in the initial state, the movable filter plate 7 is suspended on the blocking seat 305 by the top rod 702, and the pressure value detected by the pressure sensor 3051 is set to the initial value. During the venting process, the support block 603 can support the movable filter plate 7 and lift it upward. At this time, the pressure spring 704 begins to compress and deform until the movable filter plate 7 stops moving. When the venting stops, the support block 603 descends with the connecting rod 602 until it no longer supports the movable filter plate 7. At the same time, the movable filter plate 7 will also move and reset under the action of the pressure spring 704 until it is suspended again. In the hanging state, pressure sensor 3051 will re-detect the pressure value. The change in the pressure value between the two tests is the weight change of the movable filter plate 7 before and after filtration. This is used to accurately detect the weight of the air bubbles and droplets filtered and isolated on the movable filter plate 7. When the pressure change exceeds the specified threshold, pressure sensor 3051 will send a signal to open control valve 3011. This allows for automatic spray cleaning when enough air bubbles and droplets accumulate on the movable filter plate 7. Furthermore, each spraying process is carried out during the stage when exhaust is stopped, ensuring the dryness of the exhaust gas during purification and emission, and avoiding any impact on the subsequent activated carbon adsorption process.

[0039] More specifically, the purpose of using the support block 603 to lift the movable filter plate 7 is to compress the pressure spring 704, thereby enabling the movable filter plate 7 to vibrate up and down, and the bubbles and droplets will detach more quickly under the action of vibration.

[0040] like Figure 4 and Figure 5 As shown, the spray pipe 3012 is arranged around the inner wall of the purification box 3, and the spray pipe 3012 is located above the movable filter plate 7.

[0041] Specifically, by setting up spray pipes 3012 and nozzles 3013, the spray rinsing area can completely cover the movable filter plate 7, which helps to improve the spray rinsing effect.

[0042] like Figure 6 As shown, a mounting base 306 is fixedly installed on the inner wall of the purification box 3, and a fixed filter plate 8 is fixedly installed in the mounting base 306. Slide rails 307 are fixedly installed on the front and rear sides of the inner wall of the purification box 3, and the two ends of the mounting plate 608 slide in cooperation with the slide rails 307.

[0043] Specifically, when the connecting rod 602 is raised, it will drive the mounting plate 608 to move outward through the connecting rod 607, thus preventing the mounting plate 608 from obstructing the effective filtration area on the fixed filter plate 8. When the connecting rod 602 moves downward, it will drive the mounting plate 608 to move inward through the connecting rod 607. During this process, both ends of the mounting plate 608 remain within the slide rail 307, allowing the cleaning brush 609 to remain in contact with the surface of the fixed filter plate 8. As the mounting plate 608 moves back and forth, the cleaning brush 609 can scrape and clean the fixed filter plate 8.

[0044] like Figure 2 As shown, a waterproof and breathable valve 303 is installed on the connecting pipe between the purification box 3 and the activated carbon adsorption box 4. The waterproof and breathable valve 303 can prevent the cleaning liquid during the spray rinsing process from entering the activated carbon adsorption box 4.

[0045] like Figure 2 As shown, a sliding sealing ring 304 is provided between the connecting rod 602 and the top of the purification box 3. The sliding sealing ring 304 ensures that the connecting rod 602 and the purification box 3 can slide smoothly through each other, while also ensuring good sealing performance at the connection point to avoid the problem of exhaust gas escape.

[0046] The working principle of this invention is as follows: Figures 1-6As shown, when the vessel 1 discharges vented waste gas, the exhaust valve 201 is first opened. The vented waste gas passes through the exhaust pipe 2 and the condenser 202, where the organic matter in the waste gas is condensed into liquid and separated. After condensation, the waste gas continues to flow into the purification chamber 3. The gas flowing in the exhaust pipe 2 will drive the rotating impeller 204 to rotate, which will drive the synchronous gear 205 to rotate. Since the synchronous gear 205 meshes with the longitudinal tooth groove 604, the synchronous gear 205 will drive the side plate 601 to move upward, thereby causing the connecting rod 602 to drive the support block 603 to rise upward. The support block 603 will support the movable filter plate 7 and move upward synchronously. At this time, the control inlet pipe 301 is closed, and the connecting rod 602 will drive the mounting plate 608 to slide to the fixed position through the connecting rod 607. On both sides of the filter plate 8, air bubbles will be blocked on the filter plate. The filtered waste gas will continue to be introduced into the activated carbon adsorption box 4 through the pipeline for adsorption treatment. Then the gas is introduced into the gas detector 5. When the gas quality meets the emission standards, the gas will be discharged and collected through the outlet pipe 501 for recycling. When the gas quality does not meet the emission standards, the gas will be introduced into the exhaust pipe 2 through the return pipe 502 for filtration and adsorption again until the emission standards are met. When exhaust gas emission stops, the side plate 601 moves downward to reset, and the support block 603 will no longer support the movable filter plate 7. The movable filter plate 7 moves downward, and at this time, the control liquid inlet pipe 301 is opened. The liquid inlet pipe 301 will spray cleaning solution onto the movable filter plate 7, thereby spraying and rinsing the movable filter plate 7. With the up and down vibration of the movable filter plate 7, the filtered air bubbles can be quickly vibrated and detached. At the same time, as the connecting rod 602 resets and moves, the mounting plate 608 will also slide in the opposite direction on the surface of the fixed filter plate 8 through the connecting rod 607, and use the cleaning brush 609 to wash and clean the fixed filter plate 8. Thus, the filter plate can be automatically cleaned within the time interval of exhaust gas emission from the vessel 1 without disassembling the purification box 3. The cleaning efficiency is high and the cleaning effect is effectively improved.

[0047] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
