Description

Technical Field

[0001] This invention relates to the field of waste gas treatment technology, and in particular to a combined VOCs deep treatment device for packaging printing. Background Technology

[0002] In the packaging and printing industry, combined equipment is highly favored for VOCs treatment due to its advantages such as high efficiency, stability and energy saving. Among them, the "zeolite rotor adsorption concentration + RTO regenerative thermal incineration equipment" consists of a zeolite rotor concentration system, including a zeolite rotor concentration adsorption device, a three-stage dry filter device, a heat exchanger, a fan, an RTO regenerative thermal incinerator, an automatic control system and other equipment. The zeolite rotor concentrator system adsorbs and concentrates large volumes of low-concentration VOCs waste gas, and the purified gas meets emission standards. The saturated zeolite rotor area enters the desorption zone, where hot air is used for desorption. The desorbed high-concentration VOCs waste gas enters the RTO, which uses a ceramic heat storage element to store and release heat, heating the high-concentration VOCs waste gas to a high temperature (usually 760-850℃), causing it to oxidize and decompose into carbon dioxide and water vapor. This system is suitable for the purification of continuously generated large volumes of low-concentration waste gas. After desorption, zeolite needs to enter the cooling zone and be cooled to room temperature by fresh or cold air. After cooling, the zeolite re-enters the adsorption zone, forming a continuous cycle of adsorption-desorption-cooling. The lower the temperature of the cooling medium and the greater the temperature difference between it and the zeolite, the higher the heat exchange efficiency, thereby accelerating the cooling rate of the zeolite. However, in actual use, the design of zeolite honeycomb channels may be too dense. Therefore, existing cooling equipment can only make the cooling air diffuse radially along the rotor, and it is difficult to penetrate into the honeycomb channels axially. The cooling air can only quickly reduce the temperature of the zeolite surface, resulting in uneven temperature distribution inside the zeolite rotor. The temperature in some areas is too high, which makes the VOCs desorption incomplete. The residual VOCs will occupy the adsorption sites of the zeolite and affect the subsequent adsorption efficiency. Summary of the Invention

[0003] The purpose of this invention is to address the problem that the design of zeolite honeycomb channels may be too dense, thus existing cooling equipment can only diffuse the cooling air radially along the rotor, making it difficult to penetrate the honeycomb channels axially. The cooling air can only quickly reduce the temperature of the zeolite surface, resulting in uneven temperature distribution inside the zeolite rotor. The excessively high temperature in some areas leads to incomplete VOCs desorption, and the residual VOCs will occupy the adsorption sites of the zeolite, affecting the subsequent adsorption efficiency. Therefore, this invention proposes a combined VOCs deep treatment device for packaging and printing.

[0004] To achieve the above objectives, the present invention employs the following technology: a combined VOCs deep treatment device for packaging and printing. The device includes a zeolite rotor device, which includes a housing. Adsorption zones and desorption zones are respectively arranged on both sides of the housing. A plurality of zeolite filter plates for adsorbing VOCs are arranged between the adsorption zones and the desorption zones. The zeolite filter plates are rotatably arranged in an adsorption mechanism located in the middle of the housing. The adsorption mechanism includes a rotating chamber that separates the adsorption zone and the desorption zone. The rotating chamber includes a fixedly installed cavity and a cooling air duct opened at the top of the cavity. Cooling gas circulates in the cooling air duct. A baffle is rotatably arranged inside the rotary wheel cavity, and several filling cavities are slidably installed on the baffle. Each filling cavity includes a movable frame slidably arranged on the baffle, and a zeolite filter plate is installed inside the movable frame via a rotating component. When the movable frame rotates close to the cooling air duct, the rotating component drives the zeolite filter plate to rotate first to a position perpendicular to the movable frame, and then moves horizontally along the length of the baffle to insert into the flow path of the cooling gas in the cooling air duct, so that the cooling gas penetrates deep into the honeycomb channel of the zeolite filter plate. When the movable frame rotates away from the cooling air duct, the zeolite filter plate resets.

[0005] Further description of a combined VOCs deep treatment device for packaging and printing as described above: The rotating chamber also includes partition plates disposed on both sides of the chamber. The partition plates separate the cooling air duct from the adsorption zone and the desorption zone, forming an adsorption space, a desorption space and a cooling space, and are connected to the adsorption zone and the desorption zone through openings on the surface of the partition plates.

[0006] Further description of a combined VOCs deep treatment device for packaging and printing as described above: The adsorption mechanism also includes a frame installed inside the housing, on which a steering mechanism is fixedly installed. The steering mechanism includes two fixed rings that are fixedly mounted on the frame and are symmetrical, with a rotating cavity rotatably provided between the fixed rings, and an output shaft that drives the rotating cavity to rotate is mounted on the frame.

[0007] Further description of a combined VOCs deep treatment device for packaging and printing as described above: The baffle is H-shaped and fixedly installed on the rotating cavity, and air holes for cooling gas to pass through are opened on both sides of the movable frame. When the end of the movable frame is in contact with the rotating cavity, the air hole is blocked by a baffle. The air hole is disengaged from the rotating cavity after the movable frame moves horizontally.

[0008] Further description of a combined VOCs deep treatment device for packaging and printing as described above: The steering mechanism also includes a countersunk hole formed on the fixed ring, and two racks are provided on the inner wall of the countersunk hole; In addition, several connecting shafts are respectively installed through both sides of the rotating cavity, and a second bevel gear and a gear that meshes with the rack are sleeved on the connecting shafts. The gears are located inside the countersunk hole. The rotating cavity is rotatably provided with a rotating rod connected to the rotating component, and a first bevel gear that meshes with the second bevel gear is sleeved on the surface of the rotating rod.

[0009] Further description of a combined VOCs deep treatment device for packaging and printing as described above: The connecting shafts on both sides of the rotating cavity are staggered, so that there is a sufficient gap between adjacent second bevel gears and gears.

[0010] Further description of a combined VOCs deep treatment device for packaging and printing as described above: The rotating rod controls the movement of the rotating component through a guide mechanism. The guide mechanism includes a telescopic rod installed on the rotating rod, and the telescopic rod is connected to the rotating component through a fitting part. Additionally, a connector is fixedly installed on the movable frame, with sliders rotatably mounted on both sides of the connector via extension plates, and guide grooves that engage with the sliders are provided on both sides of the inner wall of the cavity.

[0011] Further description of a combined VOCs deep treatment device for packaging and printing as described above: The guide groove includes a small-radius inner ring and a large-radius outer ring on the cavity, and the axial center of the inner ring and the outer ring coincides with the axial center of the rotating cavity. The inner ring and the outer ring are connected by two transition sections. When the slider slides in the transition section, the movable frame moves horizontally.

[0012] Further description of a combined VOCs deep treatment device for packaging and printing as described above: The transition section is positioned to match the rack. When the movable frame revolves around the rotating cavity, it rotates on its own axis and then moves horizontally through the transition section. After the continuously revolving movable frame rotates to a horizontal state via another rack, it moves horizontally to its reset state via another transition section.

[0013] One of the above technical solutions has the following advantages or beneficial effects: 1. Through the adsorption and steering mechanisms, the rotating chamber drives the rotating component to revolve around the central axis via the rotating rod. Simultaneously, the rotating rod drives the rotating component to rotate around its own axis under the constraint of the movable frame. The rotating component drives the zeolite filter plate to rotate to a position perpendicular to the movable frame, so that the honeycomb channels of the zeolite filter plate are aligned with the flow path of the cooling gas in the cooling air duct. The cooling gas penetrates the honeycomb channels axially, thereby achieving the purpose of rapid cooling by penetrating the zeolite filter plate. After cooling, as the rotating chamber continues to rotate, the rotating component and the zeolite filter plate return to a horizontal position with the movable frame, and the zeolite filter plate is rotated 180°. This achieves the purpose of using different sides of the zeolite filter plate for adsorption in sequence, making the wear degree of both sides of the zeolite filter plate similar, avoiding the scrapping caused by deformation, cracking or damage of the zeolite filter plate on one side, and extending its service life. 2. Through the set guide mechanism, when the desorbed zeolite filter plate rotates to the top of the rotating cavity and enters the cooling air duct, the connector installed on the rotating part drives the slider to slide in the outer ring through the extension plate. After the slider reaches the end of the inner ring and enters the transition part, the connector starts to move until the slider reaches the end of the transition part and enters the outer ring. During this process, the connector pulls the movable frame to move horizontally along the length of the baffle. At the same time, the rotating part pulls the telescopic rod to extend through the fitting part, maintaining the connection with the rotating rod while sliding. The rotating part and the zeolite filter plate are inserted into the flow path of the cooling gas in the cooling air duct through horizontal movement, so that the cooling gas directly contacts the zeolite filter plate and penetrates into the honeycomb channel of the zeolite filter plate, further improving the cooling effect.

Detailed Implementation

[0016] The following will describe in detail, with reference to the accompanying drawings of the embodiments of the present invention, a combined VOCs deep treatment device for packaging and printing according to the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0017] To address the issue that existing cooling devices can only diffuse cooling air radially along the rotor, failing to penetrate axially into the honeycomb channels, and thus can only rapidly reduce the surface temperature of the zeolite, leading to uneven temperature distribution within the zeolite rotor and incomplete VOCs desorption in some areas. Residual VOCs then occupy adsorption sites on the zeolite, affecting subsequent adsorption efficiency. This invention proposes a combined VOCs deep treatment device for packaging and printing. Figure 1 - Figure 19 As shown: The device includes a zeolite rotor device 10, which includes a housing 11. Adsorption zones 12 and desorption zones 13 are respectively provided on both sides of the housing 11. A plurality of zeolite filter plates 14 for adsorbing VOCs are provided between the adsorption zones 12 and the desorption zones 13. Preferably, eight zeolite filter plates 14 are equidistantly arranged in a ring. The zeolite filter plates 14 are rotatably disposed in an adsorption mechanism 20 located in the middle of the housing 11. The adsorption mechanism 20 includes a rotor cavity 23 separated between the adsorption zones 12 and the desorption zones 13. like Figure 2 , Figure 4 , Figure 7 and Figure 11 As shown, a steering mechanism 30 is fixedly installed inside the housing 11 via a frame 21. The steering mechanism 30 includes two symmetrical fixed rings 31 fixedly installed on the frame 21. A rotating cavity 34 is rotatably provided between the fixed rings 31. An output shaft 22 is installed on the frame 21 to drive the rotating cavity 34 to rotate. When it is necessary to drive the zeolite filter plate 14 to rotate, the power source connected to the output shaft 22 is activated to drive the output shaft 22 to drive the rotating cavity 34 to rotate under the restriction of the fixed rings 31 on both sides. like Figure 5 and Figure 6 As shown, the rotary chamber 23 also includes partition plates 233 disposed on both sides of the chamber 231. The partition plates 233 separate the cooling air duct 232 from the adsorption zone 12 and the desorption zone 13, forming an adsorption space, a desorption space and a cooling space. The partition plates 233 are connected to the adsorption zone 12 and the desorption zone 13 through openings on their surfaces. Preferably, the openings are configured as fan-shaped to match the shape of the zeolite filter plate 14, so that the zeolite filter plate 14 has the largest contact area with the exhaust gas when it rotates to the fan-shaped opening position, thereby improving the adsorption and desorption efficiency. like Figure 7 A baffle 24 is rotatably installed inside the rotating cavity 23. The baffle 24 is H-shaped and fixedly installed on the rotating cavity 34. Several filling cavities 25 are slidably installed on the baffle 24, such as... Figure 8 and Figure 9As shown, the filling chamber 25 includes a movable frame 251 slidably disposed on the baffle 24. A zeolite filter plate 14 is installed in the movable frame 251 via a rotating component 253. When the output shaft 22 drives the rotating chamber 34 to rotate, the baffle 24 can drive the zeolite filter plate 14 to revolve around the rotating chamber 34 via the movable frame 251 and the rotating component 253. When the five zeolite filter plates 14 located below the rotating chamber 34 rotate to the fan-shaped opening, the adsorption process begins. Figures 1-4 As shown, low-concentration waste gas is injected into the shell 11 through one side of the adsorption zone 12, and enters the cavity 231 through the opening near the adsorption zone 12 to be adsorbed by the zeolite filter plate 14. The purified gas is discharged through the desorption zone 13. After the zeolite filter plate 14 is saturated, hot air at 180-220°C is introduced into the desorption zone 13. The air enters the cavity 231 through the opening on the side near the desorption zone 13 and reacts with the zeolite filter plate 14, causing the zeolite filter plate 14 to release high concentrations of VOCs into the adsorption zone 12. The VOCs are then discharged through the adsorption zone 12 for subsequent treatment. After desorption, the zeolite filter plate 14 rotates to the top of the rotating chamber 34 and enters the cooling air duct 232 for cooling. After cooling, it rotates back to the bottom of the rotating chamber 34 for circulation.

[0018] To further improve the cooling efficiency of the zeolite filter plate 14, such as Figures 10-16 As shown, the steering mechanism 30 also includes a countersunk hole 32 opened on the fixed ring 31. Two racks 33 are provided on the inner wall of the countersunk hole 32. Several connecting shafts 37 are respectively provided through both sides of the rotating cavity 34. Preferably, four connecting shafts 37 are rotatably provided on both sides of the rotating cavity 34. A second bevel gear 38 and a gear 39 that meshes with the rack 33 are sleeved on the connecting shaft 37. The gear 39 is located inside the countersunk hole 32. It should be noted that since the connecting shafts 37 rotatably provided on both sides of the rotating cavity 34 are staggered, sufficient gaps are reserved between adjacent second bevel gears 38 and gears 39, thereby avoiding hard contact caused by adjacent second bevel gears 38 and gears 39 being too close. A rotating rod 35, connected to the rotating component 253, is rotatably disposed within the rotating cavity 34. A first bevel gear 36, meshing with the second bevel gear 38, is sleeved on the surface of the rotating rod 35. When the rotating cavity 34 rotates under the drive of the output shaft 22, the rotating cavity 34 drives the rotating component 253 to revolve via the rotating rod 35. Simultaneously, the gears 39 on both sides of the rotating cavity 34 mesh and rotate with the rack 33. The number of teeth on the rack 33 is set to one-quarter of the number of teeth on the second bevel gear 38 and the gear 39. Therefore, the gear 39 can rotate 90° from the start of meshing to disengagement. Gear 39 drives the second bevel gear 38 to rotate via connecting shaft 37, which in turn drives the rotating rod 35 to rotate via the first bevel gear 36. The rotating rod 35 drives the rotating component 253 to rotate around its own axis under the constraint of the movable frame 251. The rotating component 253 drives the zeolite filter plate 14 to rotate to a position perpendicular to the movable frame 251, so that the honeycomb channel of the zeolite filter plate 14 is aligned with the flow path of the cooling gas in the cooling air duct 232. The cooling gas penetrates the honeycomb channel axially, thereby achieving the purpose of rapid cooling by penetrating the zeolite filter plate 14. After cooling, as the rotating cavity 34 continues to rotate, the gear 39 meshes with another rack 33 located in the countersunk hole 32, thereby driving the rotating component 253 and the zeolite filter plate 14 to continue rotating 90°, so that the rotating component 253 and the zeolite filter plate 14 are back to be horizontal with the movable frame 251, and the zeolite filter plate 14 is rotated 180°, thereby achieving the purpose of using different sides of the zeolite filter plate 14 for adsorption in sequence, so that the wear degree of both sides of the zeolite filter plate 14 is similar, avoiding the scrapping caused by unilateral structural deformation, cracking or damage of the zeolite filter plate 14, and extending its service life.

[0019] To further increase the contact area between the zeolite filter plate 14 and the cooling gas, such as Figures 16-19 As shown, the rotating rod 35 controls the movement of the rotating component 253 through the guide mechanism 40. The guide mechanism 40 includes a telescopic rod 41 installed on the rotating rod 35. The telescopic rod 41 is connected to the rotating component 253 through the fitting part 42. A connecting component 43 is fixedly installed on the movable frame 251. Slider 45 is rotatably arranged on both sides of the connecting component 43 through the extension plate 44. Guide grooves 46 that fit into the slider 45 are provided on both sides of the inner wall of the cavity 231. The guide groove 46 includes a small-radius inner ring 461 and a large-radius outer ring 462 disposed on the cavity 231. The axis of the inner ring 461 and the outer ring 462 coincides with the axis of the rotating cavity 34. The inner ring 461 and the outer ring 462 are connected by two transition parts 463. When the slider 45 slides in the transition part 463, the movable frame 251 moves horizontally. When the desorbed zeolite filter plate 14 rotates to the top of the rotating cavity 34 and enters the cooling air duct 232, the connector 43 installed on the rotating part 253 drives the slider 45 to slide in the outer ring 462 through the extension plate 44. After the slider 45 reaches the end of the inner ring 461 and enters the transition part 463, the connector 43 starts to move until the slider 45 reaches the end of the transition part 463 and enters the outer ring 462. During this process, the connector 43 pulls the movable frame 251 to move horizontally along the length of the baffle 24. At the same time, the rotating part 253 pulls the telescopic rod 41 to extend through the fitting part 42, maintaining connection with the rotating rod 35 while sliding. The rotating part 253 and the zeolite filter plate 14 are inserted into the flow path of the cooling gas in the cooling air duct 232 through horizontal movement, so that the cooling gas directly contacts the zeolite filter plate 14 and penetrates into the honeycomb channel of the zeolite filter plate 14, further improving the cooling effect. Preferred, such as Figure 7 and Figure 9 As shown, the movable frame 251 has air holes 252 on both sides for cooling gas to pass through. When the end of the movable frame 251 is in contact with the rotating cavity 34, the air holes 252 are blocked by the baffle 24. After the air holes 252 move horizontally with the movable frame 251, they are separated from the rotating cavity 34. The cooling gas enters the movable frame 251 through the air holes 252 and comes into contact with the zeolite filter plate 14.

[0020] It should be noted that the position of the transition part 463 is matched with the position of the rack 33. When the movable frame 251 revolves around the rotating cavity 34, it rotates through the rack 33. At this time, the rotating part 253 drives the zeolite filter plate 14 to rotate first to a position that is perpendicular to the movable frame 251, and then moves horizontally through the transition part 463 to be inserted into the flow path of the cooling gas in the cooling air duct 232 for cooling. After cooling, the continuously revolving movable frame 251 rotates to a horizontal state via another rack 33, and then moves horizontally to reset via another transition section 463, rotating to the bottom of the rotating cavity 34 to resume the adsorption operation.

[0021] Working principle: After desorption, the zeolite filter plate 14 rotates to the top of the rotating chamber 34 and enters the cooling air duct 232; Rotating cavity 34 rotates, and gears 39 on both sides mesh with rack 33. Since the number of teeth of rack 33 is one-quarter of the number of teeth of second bevel gear 38 and gear 39, gear 39 rotates 90°, driving second bevel gear 38, first bevel gear 36 and rotating rod 35 to rotate, so that rotating component 253 drives zeolite filter plate 14 to rotate to be perpendicular to movable frame 251, and cooling gas penetrates into honeycomb channel along the axial direction to cool down quickly; As the rotating cavity 34 continues to rotate, the gear 39 meshes with another rack 33, driving the rotating component 253 and the zeolite filter plate 14 to rotate another 90°, becoming horizontal with the movable frame 251 and rotating 180°, so that the wear on both sides of the zeolite filter plate 14 is similar, thus extending its service life. The connecting part 43 on the rotating part 253 drives the slider 45 to slide in the outer ring 462 through the extension plate 44. After entering the transition part 463, the connecting part 43 moves, pulling the movable frame 251 to move horizontally. The rotating part 253 pulls the telescopic rod 41 to extend, and the zeolite filter plate 14 moves horizontally and inserts into the cooling air duct 232 into the cooling gas flow path. The cooling gas enters the movable frame 251 through the air hole 252 and contacts the zeolite filter plate 14. After cooling, the movable frame 251 continues to revolve, rotates to a horizontal state via another rack 33, and then moves horizontally to reset via another transition section 463, rotating to the bottom of the rotating cavity 34 to resume the adsorption operation.
