The inside of the butt joint 1431 is positioned above the butt joint 1423 and is rotationally connected with a butt joint shaft 144, a driving cavity 1443 is formed in the inner side of the butt joint shaft 144 near the top, and a filtering component 145 is arranged on the outer wall of the butt joint shaft 144 near the driving cavity 1443.
By adopting the above technical scheme, the shunt tube 12 further diffuses the air flow through the tail end air distribution plate 122, so that the defect of insufficient reaction of the purifying liquid caused by overhigh local concentration is avoided. When the fixed frame 142 rotates along with the driving shaft 141, the pushing plate 1421 stirs the cleaning solution to enhance gas-liquid contact, and the first scraping plate 1422 simultaneously cleans the sediment on the inner wall of the cleaning chamber 11. The docking shaft 144 transmits torque to the filter assembly 145 through the drive chamber 1443, causing the screen 1454 to continue to rotate to avoid localized clogging of the viscous oligomer. The multistage gear set transmits power from the driving shaft 141 to the butt joint shaft 144, so that synchronous differential rotation of the filtering component 145 and the main shaft is realized, and the impurity stripping efficiency is optimized. The radial offset of the filter assembly 145 through the abutment shaft 144 and the stop 143 prevents seal failure.
The filter assembly 145 comprises a fixing frame 1451 fixedly mounted on the outer wall of the butt joint shaft 144, a scraping plate II 1452 is arranged on the outer wall of the fixing frame 1451 close to the inner wall of the purifying cavity 11, a plurality of transmission shafts 1453 are rotatably connected inside the fixing frame 1451, one end of each transmission shaft 1453 extends into the driving cavity 1443, a filter screen 1454 is arranged on the surface of each transmission shaft 1453, a butt joint frame 1455 is arranged on the outer wall of the fixing frame 1451 close to the top of the filter screen 1454, a collecting cavity 14551 is arranged inside the butt joint frame 1455 close to the filter screen 1454, and a slag collecting water filtering shell 1457 is slidably mounted inside the collecting cavity 14551. The top of the butting frame 1455 is provided with a baffle 14552, the bottom of the inner side of the collecting cavity 14551 is fixedly connected with a fixing block 1456 close to the position of the filter screen 1454, the top of the fixing block 1456 is hinged with a scraper plate III 14561, the top of the fixing block 1456 is provided with an elastic piece 14562 with one end connected with the scraper plate III 14561, the outer wall of the slag collecting and filtering shell 1457 is provided with a collecting opening 14572 close to the position of the scraper plate III 14561, and the bottom of the slag collecting and filtering shell 1457 is provided with a diversion inclined plane 14571.
By adopting the technical scheme, the filter screen 1454 with the surface wrapped is driven to circularly operate by the transmission gear II 1445. The design keeps the filter screen 1454 in a dynamic filtering state all the time, and static blockage is avoided. The fixing frame 1451 scrapes the inner wall of the purifying cavity 11 synchronously through the scraping plate II 1452 on the outer wall when rotating, so as to prevent sticky matters from accumulating. The collection chamber 14551 forms a semi-enclosed space with the top of the screen 1454, and the rotating screen 1454 brings contaminants into this area. The baffle 14552 prevents splashing of the purge fluid, ensuring that impurities fall directionally into the collection chamber 14551. The scraper three 14561 hinged to the fixed block 1456 is kept in elastic contact with the filter screen 1454 by the elastic member 14562, so that the deformation of the filter screen 1454 is adapted and the scraping force is ensured, especially for sticky oligomers. The collecting opening 14572 is opposite to the falling track of the scraper three 14561, and the diversion inclined surface 14571 enables impurities to slide towards the bottom of the shell for concentration. The small holes on the shell wall realize the automatic reflux of the purifying liquid, thereby avoiding the waste of the liquid. The fixing frame 1451 and the butt joint shaft 144 synchronously rotate, and the internal transmission shaft 1453 realizes differential rotation through a gear set, so that the relative motion of the filter screen 1454 and the purifying liquid is formed, and the impurity stripping effect is enhanced.
The center position of the inner side bottom of the driving cavity 1443 is rotationally connected with a driven gear 1444, the top of the driven gear 1444 is provided with a connecting rod with one end penetrating to the outer position of the butt joint shaft 144, one end of the connecting rod, which is positioned at the outer position of the butt joint shaft 144, is fixedly connected with a fixing rod 1446, two ends of the fixing rod 1446 are fixedly connected with the inner wall of the purifying cavity 11, the inside of the driving cavity 1443 is rotationally connected with a transmission gear II 1445 corresponding to the position of the filtering component 145, and the transmission gear II 1445 is meshed with the driven gear 1444.
By adopting the technical proposal, the utility model has the advantages that,
The driven gear 1444 is rigidly connected with the fixing rod 1446 through a connecting rod, and two ends of the fixing rod 1446 are anchored on the inner wall of the purifying cavity 11, so that a stable static supporting point is formed. This design ensures that the driven gear 1444 remains absolutely stationary during transmission. In addition to fixing the driven gear 1444, the fixing rod 1446 penetrates through the docking shaft 144 to form radial constraint, so that radial deviation of the docking shaft 144 during high-speed rotation is prevented, and meshing precision of the second transmission gear 1445 and the driven gear 1444 is guaranteed.
The bottom of the butt joint shaft 144 is provided with a butt joint cavity 1441, the inner wall of the butt joint cavity 1441 is uniformly provided with a plurality of butt joint teeth 1442, a first transmission gear 1432 is rotatably connected at a position, close to the butt joint teeth 1442, inside the butt joint cavity 1431, the first transmission gear 1432 is meshed with the butt joint teeth 1442, a driving gear 1424 is arranged at a position, close to the first transmission gear 1432, of the center of the top of the butt joint 1423, and the driving gear 1424 is meshed with the first transmission gear 1432.
By adopting the above technical scheme, the driving gear 1424 is fixed on the top of the butt joint 1423, is meshed with the first transmission gear 1432, and transmits the rotation power of the driving shaft 141 to the butt joint shaft 144, so as to ensure the synchronous differential motion of the butt joint shaft 144 and the driving shaft 141. The docking head 1423 rotates within the docking port 1431 and drives the first transmission gear 1432 through the drive gear 1424, ensuring axial stability of power transmission and reducing radial offset of the docking shaft 144.
The working principle and the using flow of the embodiment of the invention are as follows:
The purifying liquid is injected into the purifying cavity 11, so that the liquid level of the purifying liquid reaches the middle position of the filter screen 1454, then the waste gas is conveyed into each breather pipe 121 through the shunt pipes 12, and the waste gas is evenly shunted to different positions in the purifying cavity 11 through the breather pipes 121. The surface of the air distribution plate 122 at the top end of the air pipe 121 is provided with a plurality of small holes for dividing the concentrated air flow conveyed by the air pipe 121 into a large number of independent fine bubbles, so that the air flow is prevented from directly impacting the purifying liquid to form large bubbles to quickly rise to the liquid level, the fine bubbles can greatly increase the reaction interface between acidic substances in the waste gas and the purifying liquid, the neutralization reaction is more sufficient, and meanwhile, part of VOCs (such as ethyl acetate) which are easily dissolved in water are easier to be absorbed, and the pollutant load of the subsequent burning links is reduced.
Before the waste gas is injected into the purifying cavity 11, the driving motor 1411 is started, the driving shaft 141 is driven to rotate anticlockwise by the driving motor 1411, the driving shaft 141 rotates to drive the pushing plate 1421 in the fixed frame 142 to stir rapidly in the purifying liquid, turbulence is generated by the rapid stirring of the pushing plate 1421, the bubble motion path is continuously cut to enable the bubble to do irregular fold line motion in the purifying liquid instead of floating straight line, so that the contact time between the bubble and the purifying liquid is prolonged, meanwhile, the turbulence can prevent the bubble from gathering, ensure that each small bubble can fully contact the purifying liquid, enable neutralization reaction of acidic substances (such as acrylic acid) and the purifying liquid (such as NaOH) to be more thorough, reduce escape of unreacted acidic gases along with the bubbles, and the inner wall of the purifying cavity 11 is cleaned by the scraper 1422 when the fixed frame 142 rotates.
The pushing plate 1421 stirs and still drives the purifying liquid and forms vortex flow in purifying chamber 11 inside, and still can drive top butt joint 1423 rotatory when the drive shaft 141 rotates, and butt joint 1423 sets up in butt joint 1431 inside and is used for improving the stability of drive shaft 141, and butt joint 1423 rotates and can drive gear 1424 and rotate, and drive gear 1424 rotates and can drive first 1432 of drive gear and rotate, and first 1432 of drive gear rotates and can drive the butt joint axle 144 clockwise through butt joint tooth 1442.
The filter assembly 145 is driven to synchronously rotate while the docking shaft 144 rotates, wherein a filter screen 1454 in the filter assembly 145 is obliquely arranged, the docking shaft 144 rotates while the driving gear two 1445 is driven to rotate around the driven gear 1444, the driven gear 1444 is fixed, so that the driving gear two 1445 meshed with the docking shaft is driven to rotate, a transmission shaft 1453 with one end extending to the driving cavity 1443 is fixedly connected with the driving gear two 1445, and therefore the driving gear two 1445 drives the transmission shaft 1453 to rotate, and the transmission shaft 1453 rotates to drive the filter screen 1454 on the surface of the transmission shaft to circularly operate.
The turbulence generated by the counterclockwise rotation of the pushing plate 1421 can cut bubbles and prevent aggregation, and when the filtering assembly 145 rotates clockwise, the obliquely arranged filter screen 1454 drives the peripheral purifying liquid to form a local rotational flow in the clockwise direction, and the two opposite liquid flows collide and interweave in the purifying cavity 11 to form more complex cross turbulence. This cross turbulence can further break up the fine bubbles generated by the gas distribution plate 122, changing the motion path of the bubbles from "irregular fold lines" to "spiral rising tracks", and the residence time is prolonged more than that of the single turbulence.
Meanwhile, the reverse liquid flow can continuously push the fresh purifying liquid (the liquid which does not consume the neutralizing component) to the bubble-dense area, so that the partial purifying liquid is prevented from being invalid, the neutralizing reaction of acidic substances such as acrylic acid and NaOH is more thorough, and the amount of unabsorbed VOCs is further reduced. The turbulent flow of the pushing plate 1421 is responsible for "feeding impurities upwards", the reverse rotation of the filtering assembly 145 is responsible for "connecting impurities to the filter screen 1454", and the two cooperate to form a "directional impurity conveying channel", so that the impurities contact the filter screen 1454 more accurately, and the probability of depositing impurities at the bottom of the purifying cavity 11 is reduced while the interception efficiency is improved.
When the filter assembly 145 rotates clockwise, the surface of the filter 1454 continuously contacts the "reverse flow" caused by the turbulent flow of the pushing plate 1421, and this flow forms a "scouring force" on the surface of the filter 1454, so that the fine impurities (such as viscous oligomers) just adhered to the pores of the filter 1454 can be washed away in time, and the accumulation of the impurities on the screen surface is avoided. Meanwhile, the counter-current action of the clockwise rotation of the filter screen 1454 and the counter-clockwise turbulence of the pushing plate 1421 can generate a relative sliding friction between the filter screen 1454 and the impurities, so that some impurities are flushed into the docking frame 1455, the filter screen 1454 can also drive the impurities to move into the docking frame 1455, and the scraping plate 14561 in the docking frame 1455 can scrape the impurities on the surface of the filter screen 1454 easily. The elastic piece 14562 below the third scraper 14561 can automatically compensate the gap generated by the jump and deformation of the filter screen 1454, so that the third scraper 14561 is always attached to the filter screen 1454, the residual blocking of viscous oligomers of acrylic acid waste gas is avoided, meanwhile, the pressure of the third scraper 14561 is buffered, the baffle 14552 is used for preventing the cleaning solution driven by the rotation of the filter assembly 145 from crossing the filter screen 1454, and flushing the cleaning solution and scraped impurities can reach the collecting port 14572 along the scraper, and then enter the slag collecting and water filtering shell 1457.
The slag collecting and water filtering shell 1457 is provided with a plurality of small holes, the small holes can timely filter the purified liquid entering the shell, the liquid can flow back to the purifying cavity 11 for reuse, the purified liquid is prevented from losing along with impurities (the supplementing frequency is reduced, the cost is lowered), and meanwhile, only solid impurities (such as sticky oligomers and dust) are left in the shell, so that secondary pollution caused by backflow after mixing of the impurities and the liquid is avoided. The flow guiding inclined surface 14571 inside the slag collecting and water filtering shell 1457 adopts a tangential inclined design, and the impurities are gathered through the inclined surface, so that the inclined design is convenient to clean, the impurities (containing a small amount of residual liquid) slide to the lowest position by gravity, the impurities can not be scattered and piled in the shell (especially the viscous impurities of the acrylic acid waste gas are adapted to avoid being stuck to the shell wall), and only the concentrated impurities at the lowest position are required to be treated when the cleaning is continued, so that the cleaning is not needed to be comprehensively carried out, and the shutdown maintenance time is reduced.
In summary, compared with the prior art, the embodiment of the invention has the following advantages:
