A coating exhaust gas purification rotary drum processing system

Abstract

This invention relates to the field of waste gas treatment, and more particularly to a rotary wheel treatment system for purifying coating waste gas. The main housing has air inlets and outlets on both sides. An adsorption pipe is installed inside the housing, and a main disc is installed inside the pipe. Two symmetrical gas collection hoods are arranged on both sides of the main disc to form desorption and cooling channels. In this invention, the zeolite rotary main disc is designed as a multi-set axially extendable fan-shaped structure. During desorption, mechanical guidance causes multiple fan discs to separate and unfold, linking with internal transmission components. This introduces hot air from the source into the heating frame between the fan discs, directly introducing the high-temperature desorption airflow into the central area of ​​the disc for heating compensation. This solves the problem of insufficient desorption caused by depth temperature drop in traditional thick-layer zeolite rotary wheels, ensuring temperature stability and desorption effect during the desorption process.

Description

Technical Field

[0001] This invention relates to the field of waste gas treatment technology, and in particular to a rotary treatment system for purifying coating waste gas. Background Technology

[0002] The coating exhaust gas purification rotary treatment system is a VOCs treatment environmental engineering equipment widely used in the fields of spraying, drying and surface treatment. It mainly uses zeolite adsorption rotary wheel to concentrate large volume and low concentration organic waste gas, and then uses hot air desorption to form small volume and high concentration waste gas, which finally enters the combustion or catalytic oxidation unit for treatment, thereby achieving waste gas purification and energy saving.

[0003] Traditional zeolite discs typically employ a fixed, integrated structure with a relatively large overall thickness. During the desorption process, hot air needs to penetrate a desorption layer approximately 60cm thick. As heat transfer and airflow propel the disc, the desorption heat gradually diminishes, leading to reduced desorption efficiency in deeper areas. This can result in issues such as residual organic matter, insufficient local regeneration, and decreased purification efficiency. Furthermore, long-term operation can cause further degradation in adsorption capacity. Summary of the Invention

The space between the first and second gas collecting hoods is divided into a cooling zone and a desorption zone. An auxiliary desorption air duct is installed in the middle of the desorption zone.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] Reference Figure 1-5 A rotary treatment system for purifying coating exhaust gas includes a main housing 1. An air inlet 2 and an air outlet 201 are respectively provided on both sides of the main housing 1. An adsorption tube 202 is provided inside the main housing 1. A disc mounting ring 7 is rotatably mounted on the middle part of the adsorption tube 202 through a disc drive frame 4. A main disc 5 is installed inside the disc mounting ring 7. The disc mounting ring 7 is driven to rotate by a disc drive mechanism 41.

[0020] The disc drive mechanism 41 is installed inside the disc mounting ring 7. The disc drive mechanism 41 includes a main drive motor, a tensioning mechanism, a transmission chain and other transmission components. It drives the disc mounting ring 7 to rotate through the motor, the tensioning mechanism and the transmission chain. The structure and driving principle of the disc drive mechanism 41, which are not explained in detail above, are all conventional drive mechanisms of existing zeolite discs, so they will not be elaborated on here.

[0021] Furthermore, on both sides of the disk drive frame 4, there are symmetrically arranged gas collection hood 3 and gas collection hood 31. Gas collection hood 3 and gas collection hood 31 are used to realize the desorption and cooling functions, respectively. Both of them form a sliding sealing fit structure with the main disk 5. Among them, annular covers 6 are installed in the middle of both the first gas collecting cover 3 and the second gas collecting cover 31. The annular cover 6 and the disc mounting ring 7 form annular sliding sealing fit. The annular cover 6 covers the disc mounting ring 7. The disc mounting ring 7 has multiple air inlet slots 71 on the side facing the first gas collecting cover 3.

[0022] Furthermore, the main disk body 5 includes multiple fixed fan disks 51 arranged in a circumferential array. Each fixed fan disk 51 has an installation frame 52 installed on its outer side. The installation frame 52 serves as the installation support carrier for the fixed fan disk 51. The fixed fan disks 51 are spliced ​​together to form a complete rotary disk structure. Each fixed fan disk 51 is an adsorption medium carrier and contains zeolite adsorption material. The mounting frame 52 secures each fixed fan plate 51 within the mounting ring 7 of the plate body.

[0023] Furthermore, a cooling zone 8 and a desorption zone 9 are respectively divided between the first gas collecting hood 3 and the second gas collecting hood 31. An auxiliary desorption air duct 91 is installed in the middle of the desorption zone 9. The auxiliary desorption air duct 91, the annular cover 6, and the air inlet 71 form a connecting air duct.

[0024] Furthermore, each mounting frame 52 is provided with a connection interface 163 on the upper side. The connection interface 163 is connected to the air inlet 71 to introduce airflow, thereby introducing additional high-temperature hot air into the main plate 5 during the desorption process.

[0025] Furthermore, the sector area formed by the desorption zone 9 is larger than the sector area formed by the fixed fan disk 51. When the fixed fan disk 51 rotates into the interior of the desorption zone 9, the space it occupies cannot completely fill the entire desorption zone 9. Therefore, the fixed fan disk 51 still needs to continue rotating with the mechanism for a predetermined time to maintain a sufficient residence period in the desorption zone 9 before gradually and slowly leaving the desorption zone 9. This area difference design ensures that the turntable has sufficient time for heating or gas flushing in the desorption channel.

[0026] Reference Figure 6-11A fixed fan plate 51 is fixedly installed on one side of the mounting frame 52. The mounting frame 52 forms a U-shaped mounting structure, and its hollow interior area is used to install movable fan plate one 11 and movable fan plate two 12. The movable fan plate 11 and the movable fan plate 2 12 are connected by a linkage mechanism. The movable fan plate 11 and the movable fan plate 2 12 can perform lateral telescopic movement along the axial direction of the fixed fan plate 51 to realize the telescopic function of a single plate module.

[0027] A heating frame 10 is installed between the fixed fan plate 51, the movable fan plate one 11 and the movable fan plate two 12. The heating frame 10 is slidably installed inside the limiting groove 21 opened in the inner wall of the mounting frame 52. An arc-shaped guide block 121 is installed on the side of the movable fan plate two 12 facing the air collection hood two 31. The arc-shaped guide block 121 forms a sliding fit with the air collection hood two 31 and the end face of the annular cover 6. The linkage mechanism includes multiple limiting rods 14 and limiting rods 15. One end of each limiting rod 14 is rotatably connected to the upper part of the fixed fan disk 51, and the other end is in sliding rotational cooperation with the guide groove 13 opened on the upper part of the movable fan disk 11. Next, one end of the limiting rod 15 is rotatably mounted on the movable fan plate 11, and the other end forms a sliding rotational engagement with the upper part of the movable fan plate 12. Therefore, when the movable fan disk 11 and the movable fan disk 2 12 perform telescopic displacement, the limiting rod 14 and the limiting rod 2 15 can form a linkage support structure to achieve stable telescopic guidance and drive the corresponding connecting rod to generate synchronous deflection during the movement.

[0028] Furthermore, a rotating seat 17 is fixedly installed inside the mounting frame 52 located on the upper part of the fixed fan plate 51. The rotating seat 17 is used to rotatably connect with the limiting rod 14. The bottom of the rotating shaft of the limiting rod 14 is rotatably connected to the connecting rod 171 and the connecting rod 172 through the mounting block. The connecting rod 171 and the connecting rod 172 are symmetrically arranged, and when the limiting rod 14 rotates, the connecting rod 171 and the connecting rod 172 can generate synchronous linkage displacement with the rotation displacement.

[0029] Furthermore, an air inlet heat pipe 16 is installed inside the mounting frame 52. A connection interface 163 is provided on one side of the middle part of the air inlet heat pipe 16. The connection interface 163 is connected to the air inlet slot 71. The air inlet slot 71 can introduce high-temperature gas into the air inlet heat pipe 16. The two ends of the air inlet heat pipe 16 extend to both sides of the mounting frame 52 to form a lateral air outlet structure. Both ends are equipped with an on / off valve 161 to control the airflow. Among them, the drive wheel of the opening and closing valve 161 is rotatably connected to one end of the connecting rod 171. When the limit rod 14 rotates to drive the connecting rod 171 to deflect, the end of the connecting rod 171 generates a displacement to drive its drive wheel to rotate around the axis, thereby realizing the opening and closing valve 161 to perform the opening or closing action, thereby realizing the automatic conduction and switching control of the hot air inside the intake heat pipe 16. Specifically, the drive wheel is the drive wheel (valve stem) that controls the opening and closing of the valve core of the valve.

[0030] Reference Figure 12-16 Multiple side pipes 162 are connected to both ends of the air intake heat pipe 16. Multiple air output ports are provided in the middle of the side pipes 162. Each air output port is fitted with a sliding and sealed male connector 20. The end of the male connector 20 is embedded in the inner wall of the mounting frame 52 on both sides. Under normal working conditions, each male connector 20 is pressed and contacted with the movable fan plate 11 and the movable fan plate 2 12 respectively.

[0031] In addition, each heating rack 10 has a heat pipe docking female head 101 on its side wall that is connected to the plug-in male head 20. The heating rack 10 is hollow inside and connected to the heat pipe docking female head 101. Multiple arc-shaped supports are provided in the middle of the rack to form support. Each arc-shaped support has a jet hole 102 at its bottom. Under normal operating conditions, each heating rack 10 is sandwiched between the fixed fan plate 51 and the movable fan plate one 11, the movable fan plate one 11 and the movable fan plate two 12, and the contact surfaces of the fixed fan plate 51, the movable fan plate one 11, the movable fan plate two 12 and the heating rack 10 are all provided with matching rack mounting grooves, thus forming a complete plate structure.

[0032] Furthermore, a drive plate 22 is slidably mounted inside the mounting frame 52. Multiple protrusions 221 are mounted on the inner side of the drive plate 22. The protrusions 221 and the inclined grooves 23 opened on the side wall of the plug-in male connector 20 form a sliding fit. A gear shaft 24 is screwed to the top of the drive plate 22. A helical gear is fixedly mounted on the top of the shaft of the gear shaft 24. One side of the helical gear is meshed with a helical rack 19. The helical rack 19 is slidably mounted inside one end of the mounting frame 52.

[0033] One end of the helical rack 19 is rotatably connected to the secondary connecting rod 18, and the other end of the secondary connecting rod 18 is rotatably connected to one end of the second connecting rod 172. When the second connecting rod 172 generates a displacement due to the rotation of the first limiting rod 14, the second connecting rod 172, in conjunction with the second end of the secondary connecting rod 18, generates a lateral displacement, thereby driving the helical rack 19 to move horizontally along its mounting groove.

[0034] In this embodiment, the coating exhaust gas enters the main housing 1 through the air inlet 2 and enters the area where the main disk 5 is located through the adsorption pipe 202. The main disk 5 rotates slowly and continuously under the drive of the disk drive mechanism 41. The zeolite adsorption material filled inside each fixed fan disk 51 adsorbs and purifies the organic waste gas in the exhaust gas. The purified gas is finally discharged from the air outlet 201.

[0035] As the main disk 5 continues to rotate, each fixed fan disk 51 will periodically enter the desorption zone 9 and the cooling zone 8. Since the fan-shaped area corresponding to the desorption zone 9 is larger than the fan-shaped area corresponding to a single fixed fan disk 51, when any fixed fan disk 51 rotates into the desorption zone 9, it will not immediately leave the desorption zone, but will maintain a slow rotating and staying state inside the desorption zone 9 for a predetermined time.

[0036] Specifically, when the fixed fan disk 51 enters the desorption zone 9, the auxiliary desorption air passage 91 inside the desorption zone 9 gradually forms an alignment connection with the corresponding air inlet 71 that rotates to the zone, and the gas enters the fan body through the auxiliary desorption air passage 91, air inlet 71, and interface 163. In the conventional zeolite rotor desorption process, the hot air needs to penetrate a relatively thick adsorption layer structure. As the heat is transferred in the depth direction, it tends to gradually decrease, especially in the area near the inside of the disk, where the temperature tends to drop. This results in insufficient desorption of the deep adsorption medium.

[0037] In this mechanism, under the continuous scouring of the hot airflow inside the desorption zone 9, the movable fan disk 11 and movable fan disk 212 located inside the mounting frame 52 gradually extend and displace along the axial direction of the fixed fan disk 51 under the action of wind pressure. Since the movable fan disk 11, movable fan disk 212 and mounting frame 52 form a limiting sliding fit through the heating frame 10, the movable fan disk 11 and movable fan disk 212 can extend outward stably in the limited state, while the heating frame 10 maintains limited movement under the guidance of the limiting groove 21.

[0038] When the movable fan disk 11 and the movable fan disk 2 12 move synchronously, they will drive the corresponding limit rod 14 and limit rod 2 15 to deflect synchronously. After the limit rod 14 rotates around the rotating seat 17, its bottom rotating shaft synchronously drives the connecting rod 171 and the connecting rod 2 172 to move in linkage.

[0039] At this time, the connecting rod 171 pushes the drive wheel corresponding to the opening and closing valve 161 to rotate, causing the opening and closing valve 161 to open, thereby creating a conductive state inside the intake heat pipe 16. Meanwhile, the second connecting rod 172 drives the helical rack 19 to slide laterally along the inside of the mounting frame 52 through the secondary connecting rod 18. During the movement of the helical rack 19, it meshes with the helical gear set on the top of the gear shaft 24, thereby driving the gear shaft 24 to rotate synchronously.

[0040] Since a threaded transmission relationship is formed between the gear shaft 24 and the drive plate 22, the rotation of the gear shaft 24 will drive the drive plate 22 to move downward along the inside of the mounting frame 52. During the downward movement of the drive plate 22, multiple protrusions 221 on its inner side simultaneously form a guiding engagement with the inclined groove 23 opened on the side wall of the plug-in male connector 20. Under the guiding action of the inclined surface of the inclined groove 23, the protrusions 221 apply a lateral pushing force to the plug-in male connector 20.

[0041] Therefore, each male connector 20 gradually extends towards the heating frame 10 and eventually forms a connection with the corresponding heat pipe female connector 101; At this time, the high-temperature desorption airflow introduced by the auxiliary desorption air passage 91 enters the interior of the intake heat pipe 16 through the intake slot 71, and then continues to enter the interior of the heating frame 10 through the side pipe 162, the male connector 20 and the heat pipe docking female connector 101.

[0042] The high-temperature airflow that enters the heating rack 10 then flows slowly out through multiple jet holes 102 into the internal area between the fixed fan plate 51, the movable fan plate one 11 and the movable fan plate two 12, so as to directly compensate for the heat inside the main plate body 5. Since the hot air in this part is directly taken from the high-temperature desorption airflow inside the desorption zone 9, its temperature is synchronized with the desorption hot air. Therefore, after the hot air passes through the front area of ​​the main plate 5 and causes a temperature drop, the deep area inside the main plate 5 can be heated and compensated again through the compensation jet structure inside the heating rack 10. The desorption effect is guaranteed by ensuring the airflow temperature of the adsorbent material flowing through each fan body.

[0043] Meanwhile, since the fixed fan disk 51 has a continuous dwell time inside the desorption zone 9, the movable fan disk 11 and the movable fan disk 2 12 can remain in the deployed state during the desorption period, so that the compensating hot air inside the heating frame 10 continuously acts on the internal area of ​​the fixed fan disk 51, thereby forming a stable internal heat circulation compensation process.

[0044] Subsequently, as the fixed fan disk 51 continues to rotate with the main disk body 5 and gradually approaches the cooling zone 8, the arc-shaped guide block 121 located on the side of the movable fan disk 2 12 gradually contacts the corresponding end face of the air collection shroud 2 31 and the annular shroud 6. As the main disk 5 continues to rotate, the arc-shaped guide block 121 is subjected to compressive force under the action of relative motion, and pushes the movable fan disk 12 to retract in the opposite direction.

[0045] During the retraction of movable fan plate 2 12, it will simultaneously drive movable fan plate 1 11, limit rod 1 14 and limit rod 2 15 to perform reverse reset motion; When the limit rod 14 is reset and rotated, the connecting rod 171 returns to its original position, causing the opening and closing valve 161 to close again, thereby cutting off the hot air delivery inside the intake heat pipe 16. At the same time, connecting rod 172 drives secondary connecting rod 18 to move in the opposite direction, secondary connecting rod 18 drives helical rack 19 to slide in the opposite direction, and after helical rack 19 moves in the opposite direction, it drives gear shaft 24 to rotate in the opposite direction.

[0046] As the gear shaft 24 rotates in the opposite direction, the drive plate 22 gradually moves upward, and the protrusion 221 disengages from the pushing position of the inclined groove 23 on the side wall of the plug male head 20. Under the action of the structural reset force, each plug male head 20 gradually exits the heat pipe docking female head 101 and is re-embedded into the mounting frame 52, thereby releasing the conductive state between the heating frame 10 and the air intake heat pipe 16.

[0047] At the same time, the movable fan disc 11 and the movable fan disc 2 12 retract back into the mounting frame 52, and the heating frame 10 also returns to its initial fitting state as the structure resets, so that the entire fixed fan disc 51 returns to the overall adsorption structure.

[0048] Next, the fixed fan disk 51, after desorption, continues to rotate into the cooling zone 8. The airflow inside the cooling zone 8 cools and de-cools the zeolite adsorbent material after high-temperature desorption in order to restore its subsequent adsorption capacity. Therefore, during the periodic rotation of the main disk 5, each fixed fan disk 51 can automatically deploy its internal heat compensation structure when entering the desorption zone 9, and automatically reset and close after leaving the desorption zone 9, thus ensuring the uniformity of desorption of the thick zeolite adsorption structure and avoiding the heat attenuation caused by the thickness problem in the traditional zeolite rotating structure.

[0049] Furthermore, it should be noted that the aforementioned dynamic sealing structure is a conventional mechanical seal structure in this field, designed to achieve a dynamic sealing effect between corresponding structures. Its specific internal structure and sealing form are common knowledge to those skilled in the art and will not be elaborated here.

[0050] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
