Description

Technical Field

[0001] The present invention belongs to the technical field of waste gas treatment, and particularly relates to a printing VOC waste gas treatment system. Background Art

[0002] Printing VOC treatment is an effective treatment for volatile organic compounds (VOCs) generated during the printing process. This treatment process involves a variety of technologies, including spraying, adsorption, photocatalytic oxidation, etc., aiming to reduce VOC emissions, protect the environment and human health. Through scientific methods and advanced technologies, printing VOC treatment can significantly improve air quality and reduce environmental pollution, which is an important guarantee for the sustainable development of the printing industry.

[0003] Printing VOC waste gas treatment equipment mainly includes two categories: activated carbon adsorption devices and spray purification devices. Activated carbon adsorption devices use the porous structure of activated carbon to adsorb harmful components in the waste gas, while spray purification devices achieve the purification purpose by spraying a purification liquid (such as a water-soluble absorbent) to contact the waste gas, so that the pollutants in the waste gas dissolve or react in the purification liquid. However, these two treatment methods have their own advantages and disadvantages in actual applications, and it is often difficult to achieve an ideal treatment effect when used alone.

[0004] Currently, existing waste gas treatment equipment is generally designed to only perform activated carbon adsorption or spray purification treatment alone, and it is impossible to achieve the organic combination and synergistic effect of the two, thus limiting the improvement space of the treatment efficiency. In addition, there is an uneven utilization rate of activated carbon, and some areas are saturated prematurely, which is likely to affect the overall adsorption effect. At the same time, the contact area between the purification liquid and the waste gas in spray purification is limited, resulting in limited purification efficiency, thus affecting the overall waste gas treatment effect. Therefore, there are deficiencies and it cannot meet the purification use requirements of manufacturers. Therefore, it is necessary to further improve.

[0005] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a printing VOC waste gas treatment system is provided with the expectation of achieving a more practical value. Summary of the Invention

[0006] In order to solve the above technical problems, the present invention provides a printing VOC waste gas treatment system, which is achieved by the following specific technical means:

[0007] A printing VOC waste gas treatment system includes a tank body, an intake pipeline provided on the left side of the tank body, and an exhaust pipeline provided on the top of the tank body. It also includes a sealing component and an adsorption mechanism provided in the intake pipeline, and a purification component provided on the tank body;

[0008] The adsorption mechanism includes a transmission component disposed in the intake duct. The transmission component includes a transmission bracket and a fixed bracket fixedly assembled on the inner wall of the intake duct. A transmission impeller is movably installed on the transmission bracket. A transmission rod is fixedly assembled on the right side of the transmission impeller. The right end of the transmission rod is rotatably connected to the fixed bracket. A transmission part is movably assembled on the transmission rod.

[0009] The adsorption mechanism further includes an adsorption component disposed in the intake duct. Activated carbon for adsorbing organic pollutants in the waste gas is provided inside the adsorption component. The adsorption component includes a fluctuating rod fixedly assembled on the transmission part.

[0010] The adsorption mechanism further includes a guiding component disposed on the transmission part. By driving the transmission rod to rotate through the transmission impeller, the guiding component can enable the transmission part to rotate on the transmission rod and move reciprocally left and right at the same time, and the irregular agitation of the activated carbon in the adsorption component is carried out by the rotating and reciprocally moving left and right fluctuating rod.

[0011] As a further description of the above technical solution: Through the synergistic effect among the transmission component, the adsorption component and the guiding component, the organic pollutants in the waste gas can be adsorbed by the activated carbon, realizing the preliminary purification of the waste gas. At the same time, the continuous automatic adjustment of the position of the activated carbon is realized. Through this setting, not only the problem that the overall adsorption performance is affected due to premature saturation in some areas of the activated carbon is avoided, but also the adsorption effect of the activated carbon on the pollutants in the waste gas is enhanced.

[0012] Further, the transmission part includes a movable sleeve rod movably assembled on the outer periphery of the transmission rod. A limiting groove is formed on the inner wall of the movable sleeve rod. A limiting block is slidably installed inside the limiting groove. One side of the limiting block is fixedly assembled with the transmission rod. Connecting springs are fixedly connected between the left and right sides of the limiting block and the limiting groove wall.

[0013] As a further description of the above technical solution: Through this setting, the movable sleeve rod can rotate synchronously with the transmission rod and move reciprocally left and right on the transmission rod, so as to further change the position of the activated carbon by the reciprocally moving left and right fluctuating rod.

[0014] Further, the adsorption component includes an adsorption shell fixedly assembled on the inner wall of the intake duct. Two filter plates are fixedly assembled on the adsorption shell, and the activated carbon is located between the two filter plates.

[0015] Wherein, the movable sleeve rod passes through the filter plate and is rotatably connected to the filter plate.

[0016] As a further description of the above technical solution: The organic pollutants in the waste gas can be adsorbed by the activated carbon, realizing the preliminary purification of the waste gas.

[0017] Further, the guiding assembly includes a guiding sleeve fixedly assembled on the inner wall of the intake pipe. A guiding groove is formed on the inner wall of the guiding sleeve, and a guiding member is slidably installed in the guiding groove. A guiding rod is fixedly connected between the guiding member and the movable sleeve rod. A plurality of bumps are provided on the wall of the guiding groove of the guiding sleeve;

[0018] The guiding sleeve is in a wavy shape. By sliding the guiding member in the guiding groove of the guiding sleeve, the guiding rod can drive the movable sleeve rod to move left and right reciprocally on the transmission rod.

[0019] As a further description of the above technical solution: Through this setting, the wavy rod that moves left and right reciprocally can be used to further change the position of the activated carbon, avoiding premature saturation of some areas of the activated carbon and affecting the overall adsorption effect, thereby further enhancing the adsorption effect of the activated carbon on the pollutants in the waste gas.

[0020] Further, the closing assembly includes a closing seat fixedly assembled on the inner wall of the intake pipe. An air vent for the flow of waste gas is formed inside the closing seat. A linkage frame is arranged on the right side of the closing seat. The left side of the linkage frame is fixedly connected to a closing plate through a closing rod. By making the closing plate fit and contact with the inner wall of the closing seat, a closed structure is formed;

[0021] Among them, the air vent includes a first duct, a second duct, and a third duct arranged in sequence along the flow direction of the waste gas. The inner diameter of the first duct is larger than that of the second duct, and the inner diameter of the second duct is larger than that of the third duct.

[0022] As a further description of the above technical solution: Through this setting, the flow rate of the waste gas can be effectively increased. When the waste gas enters the third duct with a smaller inner diameter through the second duct, the flow rate of the waste gas is further increased, thereby improving the conveying efficiency of the waste gas.

[0023] Further, an induction assembly is arranged on the closing seat. The induction assembly includes an induction sleeve rod fixedly assembled in the closing seat. A movable rod is slidably installed inside the induction sleeve rod. One end of the movable rod extends to the outside of the induction sleeve rod and is fixedly connected to the linkage frame. An induction block is fixedly installed at the end of the movable rod away from the linkage frame. A support spring is sleeved on the outer periphery of the movable rod.

[0024] As a further description of the above technical solution: Through this setting, the kinetic energy of the circulation pump can be automatically adjusted, and at the same time, the elastic force of the support spring can be used to make the closing plate perform a reset movement, further improving its applicability.

[0025] Further, the induction assembly further includes three switch components arranged on the inner wall of the induction sleeve rod, and the three switch components are low gear, medium gear, and high gear from left to right;

[0026] The switch component includes a fixed housing fixedly assembled on the inner wall of the induction sleeve rod. A buffer seat is slidably installed on the fixed housing. An induction switch is arranged on the buffer seat. One end of the buffer seat away from the induction switch extends into the interior of the fixed housing, and a buffer spring is fixedly connected between the buffer seat and the fixed housing wall.

[0027] As a further description of the above technical solution: By corresponding the three induction switches to the low gear, medium gear, and high gear kinetic energy modes from left to right respectively, when the induction block contacts the induction switch, the kinetic energy of the circulation pump can be automatically adjusted by using the induction switch, and the buffer spring can avoid damage to the induction switch caused by the induction block, further improving its safety performance.

[0028] Furthermore, a spiral exhaust pipe is arranged inside the tank body. One end of the spiral exhaust pipe is fixedly connected to the intake pipe, and exhaust holes for exhausting gas are opened on both the upper and lower sides of the spiral exhaust pipe.

[0029] As a further description of the above technical solution: By setting the spiral exhaust pipe in a spiral cone shape, the exhaust gas can be discharged to different heights by using the spiral exhaust pipe, and at the same time, the discharged exhaust gas can be evenly distributed in the tank body, which is beneficial to the purification treatment of the exhaust gas.

[0030] Furthermore, the purification component includes a fixed frame fixedly assembled on the right side of the tank body. A circulation pump is fixedly assembled on the fixed frame. The left side of the circulation pump is communicated with the tank body through a first circulation pipe. A second circulation pipe is fixedly assembled on the upper side of the circulation pump. One end of the second circulation pipe away from the circulation pump is fixedly connected to a purification main pipe. A plurality of purification connecting pipes are fixedly installed on the purification main pipe. Atomizing nozzles for spraying purification liquid are fixedly assembled at the bottoms of the purification main pipe and the purification connecting pipes.

[0031] As a further description of the above technical solution: Through this setting, the exhaust gas and the purification liquid can be fully mixed and reacted, so that the remaining pollutants in the exhaust gas react chemically or are physically dissolved with the purification liquid, further purifying the exhaust gas, and the mixed purification liquid then returns to the circulation pump along the first circulation pipe to form a cycle, effectively improving the utilization rate of resources.

[0032] Furthermore, a tank door is arranged on the front side of the tank body, and a drain valve is fixedly assembled at the bottom left of the tank body;

[0033] An exhaust fan for exhausting gas is fixedly assembled inside the exhaust pipe.

[0034] As a further description of the above technical solution: The exhaust fan in the exhaust pipe can drive the purified gas to be discharged to the outside air along the exhaust pipe, ensuring that the discharged gas does not harm people's physical health and pollute the environment.

[0035] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are as follows:

[0036] 1. Through the synergistic effect among the transmission component, the adsorption component and the guiding component, the present printing VOC waste gas treatment system realizes the continuous automatic adjustment of the position of the activated carbon. By this setting, not only the problem that the overall adsorption performance is affected due to the premature saturation of some areas of the activated carbon is avoided, but also the adsorption effect of the activated carbon on the pollutants in the waste gas is enhanced.

[0037] 2. Through the synergistic effect between the sealing component and the sensing component, the present printing VOC waste gas treatment system realizes the adaptive adjustment of the output amount of the purification liquid according to the amount of waste gas input into the tank. By this setting, not only the purification efficiency of the waste gas is improved, but also the operation of the equipment becomes more intelligent and automated.

[0038] 3. Through the synergistic effect between the spiral exhaust pipe and the purification component, by setting the spiral exhaust pipe in a spiral cone shape, the waste gas can be discharged to different heights by the spiral exhaust pipe, and at the same time, the discharged waste gas can be evenly distributed in the tank, which is beneficial to the purification treatment of the waste gas.

[0039] 4. Through the synergistic effect among the sealing seat, the ventilation hole, the linkage frame and the sealing plate, the present printing VOC waste gas treatment system realizes the precise control of the waste gas flow rate. And when the waste gas transportation stops, the elastic force of the support spring will drive the linkage frame to drive the sealing plate to be in close contact with the inner wall of the sealing seat and close, thereby effectively isolating the leakage of the waste gas. By this setting, not only the sealing performance of the equipment is improved, but also the purification effect of the waste gas is further enhanced. BRIEF DESCRIPTION OF THE DRAWINGS

The transmission component 41 includes a transmission bracket 411 and a fixed bracket 412 fixedly assembled on the inner wall of the intake pipe 11. A transmission impeller 413 is movably installed on the transmission bracket 411. A transmission rod 414 is fixedly assembled on the right side of the transmission impeller 413. The right end of the transmission rod 414 is rotatably connected to the fixed bracket 412. A transmission part 415 is movably assembled on the transmission rod 414; the adsorption mechanism 40 also includes an adsorption component 42 arranged in the intake pipe 11. The inside of the adsorption component 42 is provided with activated carbon for adsorbing organic pollutants in the waste gas. The adsorption component 42 includes a wave rod 423 fixedly assembled on the transmission part 415; the adsorption mechanism 40 also includes a guiding component 43 arranged on the transmission part 415. By driving the transmission rod 414 to rotate through the transmission impeller 413, the guiding component 43 can make the transmission part 415 rotate on the transmission rod 414 and move reciprocally left and right at the same time, and use the rotating and reciprocating wave rod 423 to irregularly stir the activated carbon in the adsorption component 42; through the synergistic effect among the transmission component 41, the adsorption component 42 and the guiding component 43, the organic pollutants in the waste gas can be adsorbed by the activated carbon, realizing the preliminary purification of the waste gas, and at the same time realizing the continuous automatic adjustment of the position of the activated carbon. Through this setting, not only the problem that the overall adsorption performance is affected due to premature saturation in some areas of the activated carbon is avoided, but also the adsorption effect of the activated carbon on the pollutants in the waste gas is enhanced.

A limiting groove 4152 is opened on the inner wall of the movable sleeve rod 4151. A limiting block 4153 is slidably installed inside the limiting groove 4152. One side of the limiting block 4153 is fixedly assembled with the transmission rod 414. Connecting springs 4154 are fixedly connected between the left and right sides of the limiting block 4153 and the wall of the limiting groove 4152; by driving the limiting block 4153 to slide in the limiting groove 4152 through the transmission rod 414, the movable sleeve rod 4151 can rotate synchronously with the transmission rod 414 and move reciprocally left and right on the transmission rod 414, so as to further change the position of the activated carbon by using the reciprocating wave rod 423.

[0067] Please refer to Figures 8 to 9, the adsorption assembly 42 includes an adsorption shell 421 fixedly assembled on the inner wall of the intake pipe 11. Two filter plates 422 are fixedly assembled on the adsorption shell 421, and the activated carbon is located between the two filter plates 422. Among them, the movable sleeve rod 4151 passes through the filter plate 422 and is rotatably connected to the filter plate 422. Through the activated carbon, the organic pollutants in the waste gas can be adsorbed, realizing the preliminary purification of the waste gas.

[0068] Please refer to Figures 8 to 12 , the guiding assembly 43 includes a guiding sleeve 431 fixedly assembled on the inner wall of the intake pipe 11.

A guiding rod 432 is fixedly connected between the guiding member 433 and the movable sleeve rod 4151. A number of convex blocks 434 are provided on the guiding groove wall of the guiding sleeve 431. The guiding sleeve 431 is in a wave shape. By sliding the guiding member 433 in the guiding groove of the guiding sleeve 431, the guiding rod 432 can drive the movable sleeve rod 4151 to move left and right reciprocally on the transmission rod 414. During the rotation of the movable sleeve rod 4151, the guiding rod 432 also drives the guiding member 433 to slide in the wave-shaped guiding groove of the guiding sleeve 431, so that the movable sleeve rod 4151 rotates synchronously with the transmission rod 414 while moving left and right reciprocally on the transmission rod 414, thereby further changing the position of the activated carbon by the reciprocatingly moving wave rod 423, avoiding premature saturation of some areas of the activated carbon and affecting the overall adsorption effect, and further enhancing the adsorption effect of the activated carbon on the pollutants in the waste gas.

[0069] Please refer to Figures 4 to 5, the closing component 20 includes a closing seat 21 fixedly assembled on the inner wall of the intake duct 11.

A closing plate 25 is fixedly connected to the left side of the linkage frame 23 through a closing rod 24.

Among them, the air vent 22 includes a first duct 221, a second duct 222, and a third duct 223 arranged in sequence along the exhaust gas flow direction. The inner diameter of the first duct 221 is larger than that of the second duct 222, and the inner diameter of the second duct 222 is larger than that of the third duct 223. Since the inner diameter of the first duct 221 is larger than that of the second duct 222, and the inner diameter of the second duct 222 is larger than that of the third duct 223, the inner diameters of the first duct 221, the second duct 222, and the third duct 223 gradually decrease. When the exhaust gas enters the second duct 222 with a smaller inner diameter through the first duct 221, based on the smaller cross-sectional area, the flow rate of the exhaust gas will increase, so that the flow rate of the exhaust gas can be effectively increased. Then, when the exhaust gas enters the third duct 223 with a smaller inner diameter through the second duct 222, the flow rate of the exhaust gas further increases, thereby improving the conveying efficiency of the exhaust gas.

[0075] Specific usage method and function of this embodiment:

[0076] Working principle: When in use, first connect the pipe generating waste gas with the intake pipe 11 on the left side of the tank body 10. When it is necessary to treat the waste gas, through program control, the waste gas is transported into the tank body 10 along the intake pipe 11. A closing component 20 is arranged inside the intake pipe 11. As the waste gas is input, the wind force it carries passes through the ventilation holes 22 on the closing seat 21 and directly acts on the closing plate 25. The wind force generated during the flow of the waste gas is used to push the closing plate 25 to generate a relative displacement with the inner wall of the closing seat 21, thereby forming a gap, so that the waste gas can pass through these gaps smoothly; and during the process of the waste gas passing through the ventilation holes 22, a first hole 221, a second hole 222, and a third hole 223 are arranged in the ventilation holes 22. Since the inner diameter of the first hole 221 is larger than the inner diameter of the second hole 222, and the inner diameter of the second hole 222 is larger than the inner diameter of the third hole 223, the inner diameters of the first hole 221, the second hole 222, and the third hole 223 gradually decrease. When the waste gas enters the smaller inner diameter of the second hole 222 through the first hole 221, based on the smaller cross-sectional area, the flow rate of the waste gas will increase, thereby effectively accelerating the flow rate of the waste gas. Then when passing through the second hole 222 and entering the smaller inner diameter of the third hole 223, the flow rate of the waste gas further increases, thereby improving the conveying efficiency of the waste gas;

[0077] The waste gas passing through the closing component 20 then flows through the adsorption component 42. The waste gas passes through the filter plate 422 and contacts the activated carbon in the adsorption shell 421. The activated carbon can adsorb the organic pollutants in the waste gas to achieve the preliminary purification of the waste gas; at the same time, based on the wind force during the flow of the waste gas acting on the transmission impeller 413, the transmission impeller 413 is driven to rotate, and the rotating transmission impeller 413 drives the transmission rod 414 and the movable sleeve rod 4151 to rotate synchronously. During the rotation of the movable sleeve rod 4151, the wave rod 423 is driven to stir the activated carbon inside the adsorption shell 421, so as to continuously change the position of the activated carbon and effectively enhance the adsorption effect of the activated carbon on the pollutants in the waste gas;

[0078] During the rotation of the movable sleeve rod 4151, the guide rod 432 is also used to drive the guide member 433 to slide in the wavy guide groove of the guide sleeve 431, so that the movable sleeve rod 4151 rotates synchronously with the transmission rod 414 while moving left and right reciprocally on the transmission rod 414. Thus, the wavy rod 423 moving left and right reciprocally is used to further change the position of the activated carbon, avoiding premature saturation of some areas of the activated carbon and affecting the overall adsorption effect, thereby further enhancing the adsorption effect of the activated carbon on the pollutants in the waste gas. Moreover, during the process of the guide rod 432 driving the guide member 433 to slide in the guide groove of the guide sleeve 431, by providing a convex block 434 on the guide groove wall of the guide sleeve 431, the guide member 433 will contact the convex block 434 when sliding in the guide groove, thereby driving the rotating movable sleeve rod 4151 and the wavy rod 423 to generate vibration frequencies synchronously, further enhancing the stirring effect of the wavy rod 423 on the activated carbon;

[0079] Moreover, the preliminarily purified waste gas enters the spiral exhaust pipe 50 along the intake pipe 11, and the waste gas is input into the tank body 10 through the exhaust holes 51 on the spiral exhaust pipe 50. By setting the spiral exhaust pipe 50 in a spiral cone shape, the spiral exhaust pipe 50 can be used to discharge the waste gas to different heights, and at the same time, the discharged waste gas can be evenly distributed in the tank body 10, which is beneficial to the purification treatment of the waste gas. Meanwhile, the circulation pump 62 starts to operate under the control of an external program, driving the purification liquid to be transported along the second circulation pipe 64 into the main purification pipe 65, and then the purification liquid is evenly sprayed out by the cooperation of the purification connecting pipe 66 and the atomizing nozzle 67, and fully contacts the rising waste gas, promoting the full mixing reaction of the waste gas and the purification liquid, so that the remaining pollutants in the waste gas chemically react or physically dissolve with the purification liquid, further purifying the waste gas. Moreover, the mixed purification liquid returns to the circulation pump 62 along the first circulation pipe 63 to form a cycle, effectively improving the utilization rate of resources. And when the gas purification is completed, the exhaust fan 70 in the exhaust pipe 12 drives the purified gas to be discharged to the outside air along the exhaust pipe 12, ensuring that the discharged gas will not harm people's physical health and pollute the environment;

[0080] In addition, during the process of the waste gas pushing the closing plate 25 into the tank body 10, and through this setting, the moving stroke of the closing plate 25 is proportional to the wind force of the waste gas. When the wind force is greater, the closing plate 25 is pushed farther, and the gap opened between the closing plate 25 and the closing seat 21 is larger, allowing more waste gas to pass through; on the contrary, when the wind force is smaller, the moving stroke of the closing plate 25 is shorter, and the gap opened between the closing plate 25 and the closing seat 21 is also correspondingly reduced, realizing the fine control of the waste gas flow rate;

[0081] During the process of driving the movement of the closing plate 25 by the action of wind force, the linkage 23 is used to pull the movable rod 32 and the sensing block 33 to move at the same time, and the moving sensing block 33 can be in contact with the sensing switch 353 on the inner wall of the sensing sleeve rod 31; there are three groups of switch components 35 on the inner wall of the sensing sleeve rod 31, and there is a sensing switch 353 on each switch component 35. The three sensing switches 353 correspond to three kinetic energy modes of low gear, medium gear and high gear from left to right. When the sensing block 33 is in contact with the sensing switch 353, the kinetic energy of the circulating pump 62 can be automatically adjusted by using the sensing switch 353; when the wind force is small, the moving stroke of the closing plate 25 is also relatively close, and the amount of waste gas input into the input tank 10 is also correspondingly small. At this time, the linkage 23 uses the movable rod 32 to pull the sensing block 33 into contact with the sensing switch 353 at the low gear, thereby driving the circulating pump 62 to transport the circulating liquid with a small kinetic energy at this time, effectively improving the utilization rate of the circulating pump 62; when the wind force is large, the moving stroke of the closing plate 25 is farther, and the amount of waste gas input into the input tank 10 is also correspondingly large. At this time, the linkage 23 uses the movable rod 32 to pull the sensing block 33 into contact with the sensing switches 353 at the medium and high gears, thereby driving the circulating pump 62 to transport the circulating liquid with a large kinetic energy at this time, effectively improving the purification efficiency of the waste gas;

[0082] When the waste gas transportation stops, at this time, based on the elastic force of the support spring 34, the linkage 23 is driven to drive the closing plate 25 to be in close contact with the inner wall of the closing seat 21 and close, so as to isolate the flow of the waste gas and further improve the purification effect of the waste gas.
