Description

Technical Field

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

[0002] Printing VOC treatment is an effective way to control 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 VOCs emissions and protect the environment and human health. Through scientific methods and advanced technologies, printing VOC treatment can significantly improve air quality and reduce environmental pollution. It 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 device and spray purification device. The activated carbon adsorption device uses the porous structure of activated carbon to adsorb harmful components in the waste gas, while the spray purification device contacts the waste gas by spraying purification liquid (such as water-soluble absorbent) to make the pollutants in the waste gas dissolve or react in the purification liquid, thereby achieving the purpose of purification. However, these two treatment methods have their own advantages and disadvantages in actual applications, and it is often difficult to achieve ideal treatment effects when used alone.

[0004] At present, the existing waste gas treatment equipment is generally designed to only perform activated carbon adsorption or spray purification treatment separately, and it is impossible to achieve the organic combination and synergy of the two, which limits the room for improvement in treatment efficiency. In addition, there is uneven utilization of activated carbon, and some areas are saturated too early, which can easily affect the overall adsorption effect. At the same time, the contact area between the purification liquid and the waste gas in the spray purification is limited, which limits the purification efficiency, thereby affecting the overall waste gas treatment effect. Therefore, there are deficiencies and it cannot meet the manufacturer's purification needs. Therefore, it is necessary to further improve it.

[0075] The specific usage and function of this embodiment are as follows:

[0076] Working principle: When in use, first connect and assemble the pipe that generates exhaust gas to the air intake pipe 11 on the left side of the tank body 10. When the exhaust gas needs to be treated, the exhaust gas is transported to the inside of the tank body 10 along the air intake pipe 11 through program control. A sealing component 20 is arranged inside the air intake pipe 11. As the exhaust gas is input, the wind force it carries passes through the vent hole 22 on the sealing seat 21 and directly acts on the sealing plate 25. The wind force generated when the exhaust gas flows pushes the sealing plate 25 and the inner wall of the sealing seat 21 to produce relative displacement, thereby forming a gap, which promotes the exhaust gas to pass through these gaps smoothly; and in the process of the exhaust gas passing through the vent hole 22, a first The hole 221, the second hole 222 and the third hole 223, 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 are gradually reduced. When the exhaust gas passes through the first hole 221 and enters the second hole 222 with a smaller inner diameter, the flow rate of the exhaust gas will be accelerated due to the reduced cross-sectional area, thereby effectively accelerating the circulation speed of the exhaust gas. When the exhaust gas passes through the second hole 222 and enters the third hole 223 with a smaller inner diameter, the flow rate of the exhaust gas is further accelerated, thereby improving the transportation efficiency of the exhaust gas.

[0077] The exhaust gas passing through the closed component 20 then flows through the adsorption component 42. The exhaust gas passes through the filter plate 422 and contacts the activated carbon in the adsorption shell 421. The activated carbon can adsorb organic pollutants in the exhaust gas to achieve preliminary purification of the exhaust gas. At the same time, the wind force of the exhaust gas flows on the transmission impeller 413, thereby driving the transmission impeller 413 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 process, the movable sleeve rod 4151 drives the wave rod 423 to stir the activated carbon inside the adsorption shell 421, thereby continuously changing the position of the activated carbon, effectively enhancing the adsorption effect of the activated carbon on pollutants in the exhaust gas.

[0078] In the process of rotating, the movable sleeve rod 4151 also uses the guide rod 432 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 and reciprocates left and right on the transmission rod 414, so that the position of the activated carbon is further changed by the wave rod 423 that reciprocates left and right, so as to avoid premature saturation of some areas of the activated carbon and affect the overall adsorption effect, thereby further enhancing the adsorption effect of the activated carbon on pollutants in the exhaust gas; and in 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 protrusion 434 on the guide groove wall of the guide sleeve 431, the guide member 433 will contact the protrusion 434 when sliding in the guide groove, thereby driving the rotating movable sleeve rod 4151 and the wave rod 423 to synchronously generate a vibration frequency, thereby further enhancing the stirring effect of the wave rod 423 on the activated carbon;

[0079] The preliminarily purified exhaust gas enters the spiral exhaust pipe 50 along the air intake pipe 11, and is input into the tank body 10 through the exhaust hole 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 exhaust gas to different heights, and the exhausted exhaust gas can be evenly distributed in the tank body 10, which is beneficial to the purification of the exhaust gas. At the same time, the circulation pump 62 starts to operate under the control of the external program, driving the purified liquid to be transported along the second circulation pipe 64 to the purification main pipe 65, and then the purification connecting pipe 66 and the atomizing nozzle 67 are used in cooperation. The purified liquid is sprayed out evenly and fully contacts with the rising exhaust gas, promoting the full mixing reaction of the exhaust gas and the purified liquid, so that the remaining pollutants in the exhaust gas react chemically or physically dissolve with the purified liquid, further purifying the exhaust gas, and the mixed purified liquid is returned to the circulation pump 62 along the first circulation pipe 63 to form a circulation use, which effectively improves the utilization rate of resources; and when the gas purification is completed, the purified gas is driven by the exhaust fan 70 in the exhaust pipe 12 to be discharged to the outside air along the exhaust pipe 12, so as to ensure that the discharged gas will not harm people's health and pollute the environment;

[0080] In addition, when the exhaust gas pushes the closing plate 25 to enter the tank body 10, the movement stroke of the closing plate 25 is proportional to the wind force of the exhaust gas through this arrangement. 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 exhaust gas to pass through; on the contrary, when the wind force is smaller, the movement stroke of the closing plate 25 is shorter, and the gap opened between the closing plate 25 and the closing seat 21 is correspondingly reduced, thereby achieving fine control of the exhaust gas flow rate;

[0081] In the process of driving the closing plate 25 to move based on the wind force, the linkage frame 23 is used to pull the movable rod 32 and the induction block 33 to move, and the moving induction block 33 can contact the induction switch 353 on the inner wall of the induction sleeve rod 31; and the inner wall of the induction sleeve rod 31 has three groups of switch components 35, and each switch component 35 has an induction switch 353, and the three induction switches 353 correspond to the three kinetic energy modes of low, medium and high from left to right. When the induction block 33 contacts the induction switch 353, the induction switch 353 can be used to automatically adjust the kinetic energy of the circulation pump 62; when the wind force is small, the movement of the closing plate 25 The stroke is also relatively short, and the amount of waste gas input into the tank body 10 is also relatively small. At this time, the linkage frame 23 uses the movable rod 32 to pull the induction block 33 to contact the induction switch 353 located at the low gear, thereby driving the circulation pump 62 to transport the circulation liquid with a smaller kinetic energy at this time, effectively improving the utilization rate of the circulation pump 62; when the wind force is strong, the movement stroke of the closing plate 25 is relatively far, and the amount of waste gas input into the tank body 10 is also relatively large. At this time, the linkage frame 23 uses the movable rod 32 to pull the induction block 33 to contact the induction switch 353 located at the middle and high gears, thereby driving the circulation pump 62 to transport the circulation liquid with a larger kinetic energy at this time, effectively improving the purification efficiency of the waste gas;

[0082] When the exhaust gas delivery is stopped, based on the elastic force of the support spring 34, the linkage frame 23 is driven to drive the closing plate 25 to closely contact and close the inner wall of the closing seat 21, thereby isolating the flow of the exhaust gas and further improving the purification effect of the exhaust gas.
