Description

Technical Field

[0001] The present invention relates to the technical field of waste gas purification, and particularly to a waste gas purification and recycling device applied to a magnetic drive reactor. Background Art

[0002] In the process of chemical synthesis reactions, reactors are often used to carry out esterification, polymerization, condensation and other reactions under high temperature and high pressure conditions. When a process flow reaction is completed, it is necessary to discharge the high-temperature waste gas in the reactor, which is often called the reactor vent waste gas. Since the reactor vent waste gas has a fast release rate, a high release concentration, and its discharge is intermittent, it makes the subsequent waste gas purification very difficult.

[0003] Chinese Patent with application number CN201621337669.0 discloses a waste gas purification mechanism, including a reactor, and an air outlet pipe connected to the top end cover of the reactor. The end of the air outlet pipe is connected to a cooling box. The bottom of the cooling box is connected to a clean gas box through a connecting pipe. The bottom of the clean gas box is connected to an exhaust pipe. A plurality of cooling plates are arranged in the cooling box. A cooling cavity is formed between adjacent cooling plates. Through holes are arranged on the cooling plates. The air outlet pipe is connected to the top of the cooling box. An inclined diversion plate is arranged at the bottom of the cooling box. One side of the inclined diversion plate is connected to a water diversion valve. The above structure sets a cover plate at the top of the clean gas phase, and the inner liner can be cleaned or replaced by opening the cover plate. Since the filter plate will filter and isolate a large amount of bubble droplets during waste gas purification, in order not to affect the filtering effect of the filter plate, it is necessary to regularly clean or replace the filter plate. However, the manual cleaning method is not only cumbersome to operate, but also the cleaning effect needs to be improved. Summary of the Invention

[0016] Advantages of the present invention:

[0017] (1) By setting the transmission component, when discharging waste gas, the connecting rod drives the supporting block to lift upward, the supporting block will hold the movable filter plate and move upward synchronously.

[0018] (2) By detecting the pressure value through the pressure sensor, the change in the pressure value between the previous and the next time is the weight change of the movable filter plate before and after filtration, so as 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, so that when enough bubble droplets are accumulated on the movable filter plate, automatic spraying and cleaning can be carried out, and it is ensured that each spraying process is carried out during the stage of stopping exhaust, ensuring the dryness during the purification and discharge of waste gas and avoiding affecting the subsequent activated carbon adsorption process.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0028] See also Figure 1 and Figure 2 As shown, the present invention is a waste gas purification and recycling equipment applied to a magnetic transmission reactor, comprising a reactor body 1, a purification box 3 is fixedly provided on one side of the reactor body 1, the upper end of the reactor body 1 is connected to the purification box 3 through an exhaust pipe 2, a condenser 202 and an exhaust valve 201 are respectively provided on the exhaust pipe 2, the exhaust valve 201 is located between the condenser 202 and the reactor 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 outlet end of the gas detector 5 is connected to an outlet pipe 501, the other outlet end of the gas detector 5 is connected to a return pipe 502, the return pipe 502 is connected to the exhaust pipe 2, a transmission component 6 is provided on the exhaust pipe 2, and a movable filter plate 7 and a fixed filter plate 8 are sequentially provided in the purification box 3 from top to bottom.

[0029] Specifically, when the kettle body 1 discharges and vents waste gas, the exhaust valve 201 is first opened. The waste gas to be vented passes through the exhaust pipe 2 and then through the condenser 202. The organic matter in the waste gas is condensed into a liquid state 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 bubble particles in the gas. The bubble particles will be blocked on the filter plates. The filtered waste gas will continue to pass through the pipeline and into the activated carbon adsorption box 4 for adsorption treatment of the waste gas. Subsequently, 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 pass through the return pipe 502 and into the exhaust pipe 2 for re-filtration and adsorption until the emission standards are met.

[0030] As Figure 3 , Figure 4 and Figure 6 shown, the transmission assembly 6 includes a pair of side plates 601 symmetrically arranged on both sides of the exhaust pipe 2. The inner wall of the side plate 601 is provided with longitudinal tooth grooves 604. Extension shells 203 are arranged on both sides of the exhaust pipe 2. A rotating impeller 204 is rotatably installed in the extension shell 203. Synchronous gears 205 are fixedly sleeved at both ends of the axle of the rotating impeller 204. The synchronous gears 205 are engaged with the longitudinal tooth grooves 604. The bottom of the side plate 601 is fixedly connected with a connecting rod 602. The bottom end of the connecting rod 602 sequentially slides through the top of the purification box 3 and the movable filter plate 7. A supporting block 603 is extended on the inner side wall of the connecting rod 602. The supporting block 603 is arranged below the movable filter plate 7. A pair of mounting plates 608 are arranged in a close contact with the surface of the fixed filter plate 8. Cleaning brushes 609 are arranged in an array at the bottom of the mounting plate 608. The bottom of the connecting rod 602 is rotatably matched with one end of the connecting rod 607. The other end of the connecting rod 607 is rotatably connected with the top of the corresponding mounting plate 608. A liquid inlet pipe 301 is communicated with one side of the purification box 3. A liquid discharge pipe 302 is communicated with the bottom of the purification box 3. The side plate 601 controls the opening and closing of the liquid inlet pipe 301 during the waste gas discharge process.

[0031] Specifically, by setting the transmission component 6, when discharging waste gas, the gas flowing in the exhaust pipe 2 will drive the rotary impeller 204 to rotate. The rotary 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, so that the connecting rod 602 drives the supporting block 603 to lift upward. The supporting block 603 will hold the movable filter plate 7 and move upward synchronously. At this time, the liquid inlet pipe 301 is controlled to close. 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 realize the filtering and blocking function. When the waste gas discharge stops, the side plate 601 moves downward to reset, and the supporting block 603 will no longer hold the movable filter plate 7. The movable filter plate 7 moves downward. At this time, the liquid inlet pipe 301 is controlled to open, and the liquid inlet pipe 301 will spray cleaning liquid medicine onto the movable filter plate 7, so as to spray and wash the movable filter plate 7. Cooperating with the up and down vibration of the movable filter plate 7, the filtered bubble particles can be quickly vibrated and separated. At the same time, with the reset movement of the connecting rod 602, the mounting plate 608 will also slide reversely 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, so as to realize the automatic cleaning process of the filter plate during the time interval of the waste gas discharge from the kettle body 1 without disassembling the purification box 3, with high cleaning efficiency and effectively improving the cleaning effect.

[0032] As Figure 3 shown, support plates 206 are extended and arranged 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 end of the side plate 601. The top of the guide rod 605 slidably penetrates through the support plate 206, and a return spring 606 is arranged between the bottom of the support plate 206 and the side plate 601.

[0033] Specifically, when discharging waste gas, the rotary impeller 204 rotates, driving the synchronous gear 205 to rotate, thereby driving the side plate 601 to move upward. At this time, the side plate 601 will drive the guide rod 605 to move upward synchronously, and at the same time, the return spring 606 is compressed and deformed. When the exhaust stops, under the elastic force of the return spring 606, the side plate 601 will automatically move downward to reset, so as to facilitate the subsequent spraying and brushing processes. During this process, the guide rod 605 plays a role in limiting and guiding the up and down movement process of the side plate 601, ensuring the stability of its movement process.

[0034] As Figure 4 and Figure 5 shown, through holes for the connecting rod 602 to pass through are arranged through the two side edges of the movable filter plate 7, and the width of the supporting block 603 is much larger than the gap between the connecting rod 602 and the through hole.

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

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

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

[0038] Specifically, by setting the blocking seat 305 and the liquid inlet pipe 301, in the initial state, the movable filter plate 7 is suspended and installed on the blocking seat 305 through the top rod 702, and the pressure value detected by the pressure sensor 3051 at this time is set to the initial value. During the exhaust process, the supporting 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 exhaust stops, the supporting 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 also moves and resets under the action of the pressure spring 704 until the suspension is maintained again. In the hanging state, the pressure sensor 3051 will re-detect the pressure value. The change in the two pressure values is the weight change of the active filter plate 7 before and after filtration, so as to accurately detect the weight of the bubble droplets filtered and isolated on the active filter plate 7. When the pressure change exceeds the specified threshold, the pressure sensor 3051 will send a signal to open the control valve 3011, so that when enough bubble droplets accumulate on the active filter plate 7, spray cleaning can be automatically performed, and each spraying process is carried out in the stage of stopping exhaust, thereby ensuring the dryness of the exhaust gas during purification and emission, and avoiding affecting the subsequent activated carbon adsorption process.

[0039] More specifically, the purpose of lifting the movable filter plate 7 upward by the supporting block 603 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 be separated faster under the action of the vibration.

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

[0041] Specifically, by setting the spray pipe 3012 and the spray head 3013, the spray washing area can completely cover the movable filter plate 7, which is beneficial to improving the spray washing effect.

[0042] As Figure 6 shown, a mounting seat 306 is fixedly arranged on the inner wall of the purification tank 3, the fixed filter plate 8 is fixedly arranged in the mounting seat 306, slide rails 307 are fixedly arranged on the front and rear sides of the inner wall of the purification tank 3, and both ends of the mounting plate 608 are slidably matched with the slide rails 307.

[0043] Specifically, when the connecting rod 602 is lifted upward, the connecting rod 602 will drive the mounting plate 608 to move outward through the connecting rod 607, so as to avoid the mounting plate 608 blocking the effective filtering area on the fixed filter plate 8. When the connecting rod 602 moves downward, the connecting rod 602 will drive the mounting plate 608 to move inward through the connecting rod 607. During this process, both ends of the mounting plate 608 always slide in the slide rails 307, so that the cleaning brush 609 can always be in contact with the surface of the fixed filter plate 8. As the mounting plate 608 reciprocates, the cleaning brush 609 can scrape and clean the fixed filter plate 8.

[0044] As Figure 2 shown, a waterproof and breathable valve 303 is arranged on the connecting pipeline between the purification tank 3 and the activated carbon adsorption tank 4, and the waterproof and breathable valve 303 can prevent the cleaning liquid during the spray washing process from entering the activated carbon adsorption tank 4.

[0045] As Figure 2 shown, a sliding sealing ring 304 is arranged between the connecting rod 602 and the top end of the purification tank 3. The sliding sealing ring 304 can ensure the smooth sliding through fit between the connecting rod 602 and the purification tank 3, and at the same time ensure good sealing performance at the connection, so as to avoid the problem of waste gas escape.

[0046] The working principle of the present invention: As Figures 1-6As shown, when the kettle body 1 discharges and vents waste gas, the exhaust valve 201 is first opened. The vented waste gas passes through the exhaust pipe 2 and through the condenser 202, where the organic matter in the waste gas is condensed into a liquid state and separated. After condensation, the waste gas continues to flow into the purification box 3. The gas flowing in the exhaust pipe 2 will drive the rotating impeller 204 to rotate. 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, so that the connecting rod 602 drives the supporting block 603 to lift upward. The supporting block 603 will hold the movable filter plate 7 and move upward synchronously. At this time, the control liquid inlet pipe 301 is closed. 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. The bubble particles will be blocked on the filter plate. The filtered waste gas will continue to pass through the pipeline and into the activated carbon adsorption box 4 for adsorption treatment of the waste gas. Subsequently, the gas flows into the gas detector 5. When the gas quality meets the emission standard, the gas will be discharged and collected through the outlet pipe 501 for recycling. When the gas quality does not meet the emission standard, the gas will pass through the return pipe 502 into the exhaust pipe 2 and be filtered and adsorbed again until the emission standard is reached. When the waste gas emission stops, the side plate 601 moves downward to reset, and the supporting block 603 will no longer hold the movable filter plate 7. The movable filter plate 7 moves downward. At this time, the control liquid inlet pipe 301 is opened, and the liquid inlet pipe 301 will spray cleaning liquid medicine onto the movable filter plate 7 to spray and wash the movable filter plate 7. With the up and down vibration of the movable filter plate 7, the filtered bubble particles can be quickly vibrated and separated. At the same time, as the connecting rod 602 resets and moves, the mounting plate 608 will also slide reversely on the surface of the fixed filter plate 8 through the connecting rod 607, and the fixed filter plate 8 will be washed and cleaned by the cleaning brush 609. Thus, the automatic cleaning process of the filter plate can be realized during the time interval of the waste gas emission of the kettle body 1 without disassembling the purification box 3, with high cleaning efficiency and effectively improving the cleaning effect.

[0047] The above has described an embodiment of the present invention in detail, but the content described is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
