Description

Technical Field

[0001] This invention relates to the field of industrial VOCs waste gas treatment technology, specifically to an RTO combustion treatment device with a zeolite rotor. Background Technology

[0002] VOCs generated in industrial production pollute the environment and harm human health. RTO combustion treatment equipment with zeolite rotor is the mainstream treatment equipment at present. It consists of zeolite rotor, RTO regenerative thermal incinerator, filter device, PLC main control unit and safety protection structure. It achieves the emission of waste gas in compliance with standards through zeolite rotor adsorption and concentration and RTO high temperature incineration. In low-temperature environments, the exhaust gas temperature of existing equipment is far below the optimal adsorption operating temperature range of zeolite rotors. Furthermore, when solvent-based coatings, paints, and cleaning agents are used extensively, their VOC exhaust gas not only contains high concentrations of organic solvents but also carries a large amount of undried paint mist, resin droplets, waxes, and high-boiling-point components. These substances become extremely sticky at low temperatures and are very easy to adhere to. The problem of rapid clogging and scaling in zeolite rotors has worsened dramatically: High-viscosity paint mist, wax, and other impurities in the exhaust gas rapidly condense and adhere due to the low temperature when passing through the honeycomb channels of the zeolite rotor's adsorption zone. This not only causes physical channel blockage but also forms a hard, difficult-to-remove composite scale layer on the inner wall of the rotor. Conventional pulse backflushing or contact mechanical cleaning methods are either extremely ineffective due to the presence of sticky substances or severely wear down the zeolite material, leading to a rapid decline in adsorption performance and a shortened rotor lifespan. Existing technologies rely solely on pre-filtration, which cannot cope with such high-viscosity, easily condensing special loads and lacks active, non-contact, online anti-clogging and cleaning methods. RTO regenerators are difficult to maintain and suffer from uneven combustion. Siloxanes and high-boiling-point organic compounds in the coating exhaust gas are easily generated into white powdery silica dust or tar-like substances after incomplete combustion in the RTO, clogging the regenerator. Since the production line needs to operate continuously and cannot be frequently shut down, replacing the integrated regenerator requires shutting down and disassembling the entire furnace, resulting in huge economic losses. At the same time, the large fluctuations in the concentration and flow rate of the coating exhaust gas lead to extremely uneven temperature distribution in the combustion chamber of the traditional RTO. Local low-temperature zones result in substandard decomposition efficiency, while local high-temperature zones accelerate the sintering of the regenerator or the formation of NOx. In summary, existing general-purpose equipment cannot solve the coupling problems of rapid scaling and clogging of zeolite rotors and difficulty in replacing RTO heat storage medium and uneven temperature when facing low temperature, high viscosity and continuous production coating. Furthermore, it lacks a systematic structural solution that can link the anti-clogging structure with the RTO waste heat channel and intelligent control. Summary of the Invention

[0003] The purpose of this invention is to provide an RTO combustion treatment device with a zeolite rotor, which solves the technical defects of existing technology in scenarios such as automobile painting, furniture spraying, and printing coating, where high-viscosity paint mist and resin droplets in the exhaust gas easily cause zeolite rotor blockage and scaling, resulting in decreased adsorption performance. Furthermore, existing equipment can only clean the blockage after the fact and cannot solve the problem at the source. This invention achieves integrated treatment of source blockage prevention, online ash removal, efficient incineration and waste heat recovery, thereby improving the stability of equipment operation and the efficiency of exhaust gas treatment.

The regenerative arrays on both sides correspond to the flue gas inlet and the flue gas outlet, respectively. The regenerative array is composed of multiple independent and side-by-side regenerative sub-units, and each regenerative sub-unit is equipped with an independent maintenance door. The combustion chamber is equipped with a temperature partition, which divides the combustion chamber into a preheating zone, a main combustion zone, and a uniform temperature zone along the airflow direction. The uniform temperature zone is equipped with a baffle plate. The waste heat utilization pathway includes a first flue gas duct and a second flue gas duct. The first flue gas duct connects the flue gas outlet of the RTO regenerative thermal oxidizer to the desorption zone inlet of the zeolite rotor. The second flue gas duct connects the flue gas outlet of the RTO regenerative thermal oxidizer and extends to the outlet side of the blade-type air outlet array.

[0004] Furthermore, a partition plate is provided between the oleophobic adhesive layer and the paint mist condensation mesh, and the surface of the partition plate is provided with vent holes. The edge of the partition plate is fixedly connected to the inner wall of the de-adhesive housing.

[0005] Furthermore, the air guide is funnel-shaped, with the top opening corresponding to the working area of ​​the blade-type air outlet array and the ultrasonic vibration plate, and a dust discharge port at the bottom.

[0006] Furthermore, the dust outlet of the guide hood is provided with a detachable dust collection box, which is sealed to the dust outlet; the bottom of the detachable dust collection box is provided with a dust outlet, which is connected to a bypass pipe, and the other end of the bypass pipe is connected to the flue gas pipe at the flue gas inlet of the RTO regenerative thermal oxidizer through a tee fitting; the bypass pipe is provided with a shut-off valve and a check valve, and the tee fitting is provided with a tee switching valve.

In the following description, when referring to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application.

[0016] The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The singular forms “a,” “the,” and “the” used herein are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

[0017] The following detailed description of the specific implementation methods, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided in detail.

[0018] Example 1, please refer to Figures 1-5 This embodiment provides an RTO combustion treatment device with a zeolite rotor 4. The entire device is mounted and supported by a frame 1, which provides a stable mounting foundation for each functional component, ensuring the overall structure of the device is robust and reliable. The de-adhesion component 2, filter component 3, zeolite rotor 4, RTO regenerative thermal oxidizer, waste heat utilization passage 9, and PLC main control unit are all rationally arranged on the frame 1. Each functional component is arranged sequentially along the waste gas treatment process to achieve continuous and stable treatment of VOCs waste gas under low temperature and high viscosity conditions. In this embodiment, the de-adhesion assembly 2 is fixedly installed at the front end of the frame 1 along the airflow direction, including a de-adhesion housing 21, an oleophobic adhesive layer 22, a paint mist condensation mesh 23, and a separator plate 24. The de-adhesion assembly 2 has an air inlet and an air outlet, and the air outlet is connected to the air inlet of the filter housing 31. The de-adhesion housing 21 is used to form a closed airflow channel. The oleophobic adhesive layer 22 and the paint mist condensation mesh 23 are arranged close to the inner wall of the de-adhesion housing 21 and fill the inner cross section of the housing. This can intercept and remove high-viscosity paint mist, resin droplets, wax, and high-boiling-point components in the exhaust gas from the source, preventing sticky impurities from entering the subsequent structure and causing blockage. The separator plate 24 is set between the oleophobic adhesive layer 22 and the paint mist condensation mesh 23. It has vent holes on its surface and its edge is fixedly connected to the de-adhesion housing 21. This is used to maintain the distance between the two layers and make the airflow pass through evenly, improving the pre-de-adhesion effect and reducing the risk of scaling and blockage of the zeolite rotor 4 from the source. The above technical solution can achieve the goal of removing viscous impurities at the source and reducing the risk of scaling and clogging of the zeolite rotor 4. First, an oleophobic adhesive layer plate 22 that is closely attached to the inner wall of the shell and has a full cross-section and a paint mist condensation net 23 are used to efficiently capture high-viscosity paint mist, resin droplets and other components from the airflow by using physical interception and surface adhesion synergistic technology. Second, a partition plate 24 with ventilated holes is set between the two layers to maintain a uniform flow field through uniform airflow technology and prevent local airflow short circuits or impurity escape. Third, the overall structure forms a closed airflow channel to ensure that all exhaust gas undergoes de-adhesion treatment, thereby reducing the risk of scaling at the source before the exhaust gas enters the subsequent system.

[0019] The filter assembly 3 is fixedly installed on the frame 1 and includes a filter housing 31, a pre-filter 32, a medium-efficiency filter 33, and a demister 34. The filter housing 31 has an air inlet and an air outlet, and the air outlet of the filter housing 31 is connected to the adsorption zone inlet of the zeolite rotor 4 through a pipeline. The filter housing 31 forms an independent sealed filter chamber. The pre-filter 32 is a coarse-pore plate filter structure, which is installed vertically and fully sealed in the chamber near the air inlet. The medium-efficiency filter 33 is a fine fiber plate filter element, which is also vertically filled in the cross section of the chamber. The surface is located behind the primary filter 32; the demister 34 is a baffle plate demister structure with a vertically sealed cavity arranged near the outlet; the three are arranged in sequence along the direction of exhaust gas flow and their outer edges are sealed and fitted to the inner wall of the shell, with no airflow bypass gap. The exhaust gas passes through the primary coarse filter, the medium-efficiency fine filter, and the baffle demister for dehydration in sequence. This is used to classify and purify the exhaust gas after de-adhesion treatment, remove residual fine particles and water mist, further reduce the impurity content entering the zeolite rotor 4, ensure the stability of the rotor adsorption conditions, and allow the purified exhaust gas to smoothly enter the adsorption treatment stage. The above technical solution can achieve the purpose of graded purification and further reduce the impurity content: First, a three-stage series technology is adopted, consisting of a primary filter 32 (coarse-pore plate filter), a medium-efficiency filter 33 (fine fiber plate), and a demister 34 (baffle plate demister structure), to complete coarse filtration, fine filtration, and dehydration in sequence along the airflow direction, removing residual fine particles and water mist step by step; Second, each filter is installed with full-section sealing and is sealed to the inner wall of the shell, using airflow sealing technology without bypass gaps to ensure that all airflow is filtered and to avoid unpurified gas bypassing; Third, vertical arrangement and outer edge sealing technology ensure stable filtration efficiency and provide clean air intake conditions for the zeolite rotor 4.

[0020] The zeolite rotor 4 is supported and mounted on the frame 1 by a rotating shaft 41. The rotating shaft 41 is connected to the drive motor, which drives the entire honeycomb rotor to rotate continuously. The zeolite rotor 4 has a honeycomb channel 42 that runs through the axial direction inside, which is used to adsorb and concentrate VOCs components in the exhaust gas. The rotor is divided into an adsorption zone, a desorption zone, and a cooling zone around the rotating shaft 41. Each zone has an independent airflow channel and airflow inlet and outlet. The outer cover of the zeolite rotor 4 is equipped with a fixed hood. The airflow interfaces corresponding to the adsorption zone and the desorption zone are all opened on the fixed hood. The interface of the adsorption zone is connected to the waste gas to be treated after de-adhesion and filtration pretreatment to complete the adsorption of pollutants. The interface of the desorption zone is connected to the waste heat air from the incineration for regeneration and desorption, and the high-concentration waste gas after desorption and enrichment is transported to the RTO regenerative thermal oxidizer 8. The hood corresponding to the cooling zone has no external process pipeline. It is used to receive the high-temperature honeycomb section after the desorption operation for natural heat dissipation and cooling. After the honeycomb recovers to the appropriate adsorption temperature, it rotates back to the adsorption zone with the rotor to realize continuous cycle operation. The blade-type air outlet array 5 is fixed on the frame 1 by the mounting frame 51 and is located on the outer side of the end face of the zeolite rotor 4, maintaining a non-contact gap with the end face of the rotor. The array consists of an arc-shaped air knife body 52 and an air supply branch pipe 53. The arc-shaped air knife body 52 is adapted to the outer circumferential surface of the zeolite rotor 4 and is evenly arranged along the inner side of the mounting frame 51. The air outlet faces the honeycomb channel 42 and is used to spray airflow into the rotor channel to peel off attached impurities. The ultrasonic vibrating plate 6 is embedded in the edge of the blade-type air outlet array 5, and works in conjunction with the jet structure to achieve non-contact cleaning and descaling, avoiding damage to the impeller, while improving the scale removal effect. The flow guide hood 7 is located below the zeolite rotor 4, with its opening corresponding to the working area of ​​the blade-type air outlet array 5 and the ultrasonic vibrating plate 6, used to collect the impurities that have been cleaned and stripped. The bottom of the flow guide hood 7 is provided with a dust discharge port 71, and a detachable dust collection box 72 is installed at the dust discharge port 71 to collect impurities and facilitate regular cleaning. The bottom of the detachable dust collection box 72 is connected to a bypass pipe 11, which is connected to the flue gas inlet pipe of the RTO regenerative thermal oxidizer 8 through a three-way fitting 12. The pipe is equipped with a shut-off valve, a check valve, and a three-way switching valve, which can guide the collected impurities into the furnace for incineration to avoid secondary pollution and achieve closed-loop treatment of impurities. The above technical solution can achieve the goals of adsorption concentration, non-contact online unblocking, and closed-loop treatment of impurities: First, the zeolite rotor 4 is continuously rotated by the circumferential partitioning technology of the adsorption zone, desorption zone, and cooling zone driven by the rotating shaft 41, completing the adsorption-desorption-cooling cycle to achieve VOCs concentration; Second, the blade-type air outlet array 5 sprays airflow into the honeycomb channel 42, combined with the ultrasonic vibration plate 6 embedded in the edge of the air outlet, and achieves non-contact unblocking and descaling through the synergistic technology of pneumatic stripping and high-frequency vibration, avoiding mechanical damage; Third, the guide hood 7 is set up to receive the stripped impurities, and the impurities are introduced into the RTO for incineration through the detachable dust collection box 72, bypass pipe 11, and tee fitting 12, and the negative pressure conveying and valve switching technology is used to achieve closed-loop treatment of impurities and prevent secondary pollution.

[0021] The RTO regenerative thermal oxidizer 8 is located at the rear end of the equipment and is connected to the desorption zone outlet of the zeolite rotor 4 through a flue gas duct. It is used to receive high-concentration VOCs waste gas and perform high-temperature incineration and decomposition. The furnace body is equipped with a combustion chamber 81 and a split regenerative array. The regenerative array consists of multiple independent regenerative sub-units 82 arranged side by side. Each regenerative sub-unit 82 is equipped with an independent maintenance door 83, which can realize online maintenance and replacement of a single module without the need for overall shutdown and furnace dismantling, thus reducing the maintenance cost and downtime loss of the continuous production line. The above technical solutions can achieve the goals of efficient combustion, convenient maintenance, and temperature uniformity: First, a split-type heat storage array is adopted, which consists of multiple independent side-by-side heat storage units 82. Each unit corresponds to an independent maintenance door 83. Modular online replacement technology is used to achieve non-stop maintenance and reduce downtime losses. Second, a temperature partition plate 84 is set in the combustion chamber 81 to divide the combustion chamber 81 into a preheating zone, a main combustion zone, and a uniform temperature zone. Staged heating technology is used to avoid local overheating or undercooling. Third, louvered baffles 85 are arranged in the uniform temperature zone to balance the airflow and temperature distribution in the furnace through turbulence mixing technology, thereby improving VOCs decomposition efficiency and suppressing NOx generation.

[0022] The combustion chamber 81 is divided into a preheating zone, a main combustion zone, and a uniform temperature zone by a temperature partition 84. The uniform temperature zone is equipped with a louvered baffle 85. The temperature partition 84 has through-flow holes. The baffles 85 are arranged at intervals along the height direction to balance the airflow and temperature distribution in the furnace, improve the VOCs decomposition efficiency, and avoid incomplete decomposition or NOx exceeding the standard caused by uneven local temperature.

[0023] The waste heat utilization pathway 9 includes a first flue gas duct 91 and a second flue gas duct 92. The first flue gas duct 91 connects the flue gas outlet of the RTO regenerative thermal oxidizer to the desorption zone inlet of the zeolite rotor 4, transporting the high-temperature waste heat in the furnace to the desorption stage to ensure desorption efficiency. The second flue gas duct 92 connects to the flue gas outlet and extends to one side of the blade-type air outlet array 5, providing waste heat heating for the scavenging gas source, improving the unblocking effect under low-temperature conditions. The dual-path structure realizes the cascade utilization of waste heat and reduces the overall energy consumption of the system. The above technical solution can achieve the goal of cascade utilization of waste heat and reduction of system energy consumption: First, a first flue gas duct 91 is set up to connect the RTO flue gas outlet and the desorption zone inlet of the zeolite rotor 4, so as to directly supply the desorption heat with the high-temperature flue gas waste heat, thereby reducing external energy consumption; Second, a second flue gas duct 92 is set up to connect the RTO flue gas outlet and the cleaning gas source side of the blade-type air outlet array 5, so as to use waste heat to heat the cleaning airflow and improve the impurity removal effect under low temperature conditions; The two parallel paths form a dual-branch waste heat distribution technology, which rationally distributes heat according to the different temperature requirements of desorption and cleaning, thereby achieving efficient recovery and cascade utilization of waste heat.

[0024] The dust sensor 10 is arranged on the outer side of the end face of the zeolite rotor 4 and beside the blade-type air outlet array 5 to monitor the accumulation of impurities on the rotor surface in real time. The PLC main control unit is integrated into an independent electrical control box, which is installed in the operating area on the side of the frame 1, away from the high-temperature cavity and the exhaust gas channel, which facilitates wiring, equipment operation and daily maintenance. The dust sensor 10, the blade-type air outlet array 5, the ultrasonic vibrating plate 6 and the guide shroud 7 are all electrically connected to the PLC main control unit. The PLC main control unit is used to receive monitoring signals and automatically control the execution of the unblocking program to realize intelligent collaborative control of the entire process of the equipment, thereby improving the stability of operation and the reliability of treatment.

[0025] The device described in this embodiment, through its integrated structural design of pre-de-adhesion, staged filtration, non-contact unblocking, split-type regenerative thermal incineration, and dual-path waste heat recovery, can effectively adapt to the treatment conditions of low-temperature, high-viscosity coating waste gas. It avoids clogging and scaling of the zeolite rotor 4 from the source, while improving RTO incineration efficiency and maintenance convenience. With the help of intelligent monitoring and automatic control, the entire set of equipment can achieve stable, efficient, and energy-saving operation, ensuring that the waste gas treatment effect meets the standards.

[0026] Example 2: This example describes an RTO combustion treatment device with a zeolite rotor 4, including a frame 1, a de-sticking assembly 2, a filter assembly 3, a zeolite rotor 4, an RTO regenerative thermal oxidizer 8, a waste heat utilization passage 9, and a PLC main control unit. The frame 1 is provided with a de-adhesion component 2, and the de-adhesion component 2 is fixedly installed at the front end of the frame 1; the frame 1 is fixedly connected to the filter component 3, and the filter component 3 is installed on the frame 1 and located behind the de-adhesion component 2; wherein, the relative positional relationship between the de-adhesion component 2 and the frame 1 is as follows: the de-adhesion component 2 is located at the front edge of the frame 1 and is at the uppermost position along the airflow direction.

[0027] By adopting the above technical solution, the equipment achieves structural stability and orderly process by using the frame 1 as the overall load-bearing foundation and fixing each functional component in sequence according to the airflow direction; by using the front-end installation technology, it is ensured that the de-sticking component 2 plays a role as soon as the exhaust gas enters the equipment, intercepting sticky impurities from the source and preventing them from entering subsequent components. The outlet of the de-adhesion component 2 is connected to the inlet of the filter component 3 via a pipeline, and the de-adhesion component 2 is located upstream of the airflow of the filter component 3; the outlet of the filter component 3 is connected to the adsorption zone inlet of the zeolite rotor 4 via a pipeline, and the filter component 3 is located upstream of the airflow of the zeolite rotor 4; wherein, the relative positional relationship between the de-adhesion component 2 and the filter component 3 is as follows: the de-adhesion component 2 and the filter component 3 are connected in series, and the outlet of the de-adhesion component 2 is directly connected to the inlet of the filter housing 31 via a pipeline, and there are no other processing units between the two.

[0028] By using a tiered series pipeline connection technology, the three treatment units of desiccation, filtration, and adsorption are connected in series to achieve tiered treatment of waste gas from coarse pretreatment to fine purification. By using direct pipeline connection without bypass technology, all waste gas is ensured to pass through each unit in sequence, avoiding airflow short circuits and ensuring treatment efficiency.

[0029] The outlet of the filter assembly 3 is connected to the inlet of the adsorption zone of the zeolite rotor 4 through a pipeline, and the filter assembly 3 is located upstream of the airflow of the zeolite rotor 4; the zeolite rotor 4 is connected to the drive motor through the rotating shaft 41, and the drive motor is located on one side of the axial direction of the zeolite rotor 4; the relative positional relationship between the filter assembly 3 and the zeolite rotor 4 is as follows: the filter assembly 3 is set in front of the zeolite rotor 4, and the two are connected in series through a pipeline, and the outlet pipeline of the filter assembly 3 is connected to the inlet of the adsorption zone of the zeolite rotor 4.

[0030] Through pipeline series connection and motor drive transmission technology, the filtered clean waste gas is stably transported to the rotary adsorption zone, and the rotary wheel rotates continuously and at a constant speed. Utilizing the drive technology of the rotating shaft 41, the zeolite rotary wheel 4 can complete the adsorption-desorption-cooling cycle at a constant speed, ensuring the continuity of the adsorption concentration operation.

[0031] The zeolite rotor 4 is supported on the frame 1 by a rotating shaft 41, and the zeolite rotor 4 is located in the middle region of the frame 1; the frame 1 is fixedly connected to the blade-type air outlet array 5, and the blade-type air outlet array 5 is fixed on the frame 1 by a mounting frame 51 and located outside the end face of the zeolite rotor 4; wherein, the relative positional relationship between the zeolite rotor 4 and the blade-type air outlet array 5 is as follows: the blade-type air outlet array 5 faces the end face of the zeolite rotor 4, the two maintain a non-contact gap, and the air outlet faces the honeycomb channel 42 of the zeolite rotor 4.

[0032] By employing a non-contact gap arrangement technology, the blade-type air outlet array 5 is positioned directly opposite the end face of the rotor while maintaining a certain distance. The airflow jet principle is used to remove impurities without contacting the rotor material. This technology avoids the wear and tear on the zeolite material caused by mechanical cleaning, achieving online unclogging without damaging the rotor.

[0033] The edge of the blade-type air outlet array 5 is fixedly connected to the ultrasonic vibrating plate 6, and the ultrasonic vibrating plate 6 is embedded in the edge; the ultrasonic vibrating plate 6 is arranged opposite to the end face of the zeolite wheel 4, and the vibrating plate faces the honeycomb channel 42 of the zeolite wheel 4; wherein, the relative positional relationship between the blade-type air outlet array 5 and the ultrasonic vibrating plate 6 is as follows: the ultrasonic vibrating plate 6 is installed close to the air outlet edge of the blade-type air outlet array 5, and the two together constitute a blockage clearing unit facing the end face of the zeolite wheel 4, and the vibration surface of the ultrasonic vibrating plate 6 is consistent with the airflow direction of the air outlet.

[0034] By combining airflow stripping from the blade-type air outlet with high-frequency crushing by the ultrasonic vibrating plate 6, the system achieves a highly efficient, non-contact, and non-damaging unclogging effect.

[0036] The large opening of the guide shroud 7 collects the stripped impurities and discharges them through the bottom dust outlet 71. The detachable dust collection box 72 uses a sealed connection technology, which facilitates regular cleaning, prevents impurities from being re-entrained, and achieves effective collection of cleaning impurities.

[0038] The collected impurities are transported to the RTO inlet via bypass pipe 11, and then merged into the main flue gas pipe through tee fitting 12, entering the incinerator for high-temperature decomposition along with the high-concentration waste gas. A shut-off valve controls the on / off state, a check valve prevents flue gas backflow, and a tee switching valve flexibly switches the path to achieve a closed-loop treatment of impurities, avoiding secondary pollution.

[0040] The high-concentration VOCs waste gas generated in the desorption zone of the zeolite rotor is stably fed into the RTO incinerator; by utilizing the arrangement of the RTO downstream of the rotor, the waste gas flow is ensured to be unidirectional and without back mixing, providing a stable gas source for subsequent high-temperature decomposition.

[0042] The high-temperature flue gas after RTO incineration is guided back to the desorption zone of zeolite rotor 4 through the first flue gas duct 91, providing a heat source for VOCs desorption; this technology realizes the direct reuse of incineration waste heat, greatly reduces external heating energy consumption, and improves the system energy utilization rate.

Based on the sensor feedback signals, the PLC automatically adjusts the jet intensity, vibration frequency, and dust removal action to achieve adaptive adjustment of the unclogging program and overall machine linkage control, reducing manual intervention and improving operational stability.

[0049] This embodiment details the specific operation process of the RTO combustion treatment equipment with zeolite rotor 4 described above. Taking the low-temperature, high-viscosity VOCs waste gas generated in automotive painting, furniture spraying, and printing coating scenarios as an example, it demonstrates the complete workflow of the equipment from start-up to shutdown. It focuses on how the equipment solves the technical defects of the existing technology, such as easy clogging of zeolite rotor 4, inconvenient clogging removal, high maintenance cost, and low waste heat utilization rate, and achieves the integrated treatment goal of source clogging prevention, online ash removal, efficient incineration and waste heat recovery. After the equipment is started, the PLC main control unit starts first, performing system initialization and comprehensive status self-checks on all functional components of the machine. It focuses on checking the sealing of each pipeline, the reliability of electrical connections, the valve opening and closing status, and the sensitivity of sensors. After ensuring that there are no abnormalities, it controls all functional components to enter the standby state in sequence. Among them, the zeolite rotor 4 starts to rotate at a constant speed around the shaft 41 under the transmission of the drive motor. The rotation speed is kept stable to ensure the continuous connection between adsorption and desorption. The RTO regenerative thermal oxidizer 8 starts the heating program simultaneously, gradually heating to the high temperature required for the full decomposition of VOCs and keeping it stable. The entire system smoothly enters the fully automatic operation mode, making full preparations for subsequent waste gas treatment. The exhaust gas first enters the de-adhesion component 2 under negative pressure. As the core structure for exhaust gas pretreatment, the component's de-adhesion shell 21 forms a closed airflow channel, ensuring that all exhaust gas passes through the pretreatment stage without leakage. Inside the de-adhesion shell 21, the exhaust gas passes sequentially through the oleophobic adhesive layer 22, the separator 24, and the paint mist condensation mesh 23 along the airflow direction. The oleophobic adhesive layer 22 can quickly adsorb the high-viscosity paint mist and resin droplets in the exhaust gas, while the paint mist condensation mesh 23 further intercepts fine sticky particles, waxes, and high-boiling-point components. The vent holes on the surface of the separator 24 can maintain a reasonable distance between the oleophobic adhesive layer 22 and the paint mist condensation mesh 23, allowing the airflow to pass through evenly and avoiding incomplete de-adhesion caused by excessively fast local airflow. This intercepts and removes sticky impurities from the exhaust gas at the source, fundamentally reducing the risk of blockage and scaling in subsequent structures, and achieving the core design objective of preventing blockage at the source. After desiccation, the waste gas flows smoothly into the filter assembly 3 through the pipeline. The filter assembly 3 forms an independent filter chamber through the filter housing 31 to prevent the purified waste gas from mixing with the untreated waste gas. In the filter chamber, the waste gas passes through the pre-filter 32, the medium-efficiency filter 33 and the demister 34 in sequence along the airflow direction to complete the staged purification. The pre-filter 32 mainly removes the larger fine particles remaining in the waste gas, the medium-efficiency filter 33 further filters fine dust, and the demister 34 removes water mist from the waste gas. The three work together to reduce the impurity content in the waste gas to a minimum, providing stable and clean air intake conditions for the subsequent adsorption operation of the zeolite rotor 4, preventing fine impurities from entering the honeycomb channels 42 of the zeolite rotor 4, further ensuring the adsorption performance of the rotor and preventing the adsorption efficiency from decreasing. The purified waste gas is precisely fed into the adsorption zone of the zeolite rotor 4 through a pipeline. The zeolite rotor 4 has a honeycomb channel 42 that runs through the axis, which increases the contact area between the waste gas and the adsorption material of the rotor. The VOCs components in the waste gas are efficiently adsorbed and trapped by the adsorption material in the honeycomb channel 42. After the clean gas meets the emission standards after adsorption treatment, it is directly discharged through the exhaust pipeline. The zeolite rotor 4 rotates continuously and uniformly with the shaft 41. The area after adsorption saturation gradually enters the desorption zone. Under the heating effect of the waste heat flue gas, the VOCs components adsorbed in the honeycomb channel 42 are rapidly desorbed, forming high-concentration VOCs flue gas. The desorbed rotor area continues to rotate and enters the cooling zone. After cooling, it enters the adsorption zone again, realizing the continuous cycle of adsorption, desorption and cooling, ensuring the equipment's continuous treatment capacity for waste gas. During the continuous operation of the zeolite rotor 4, the blade-type air outlet array 5 and the ultrasonic vibrating plate 6 are activated synchronously to achieve non-contact online cleaning and descaling. The blade-type air outlet array 5 is fixed as a whole by the mounting frame 51. The arc-shaped air knife body 52 is adapted to the outer circumference of the zeolite rotor 4 and is evenly arranged along the inner side of the mounting frame 51. The air supply branch pipe 53 continuously provides cleaning air source to the arc-shaped air knife body 52. ​​The air knife outlet faces the honeycomb channel 42 of the zeolite rotor 4 and sprays out a uniform airflow, which can quickly peel off the impurities and scale layer attached to the inner wall of the honeycomb channel 42. The ultrasonic vibrating plate 6 is embedded in the edge of the blade-type air outlet array 5 and works in conjunction with the air jet structure to further break up the stubborn scale layer through high-frequency vibration, thereby improving the cleaning and descaling effect. At the same time, due to the non-contact design, damage to the adsorption material of the zeolite rotor 4 can be effectively avoided. The cleaning operation can be completed without stopping the machine, which greatly improves the continuity of equipment operation. The stripped impurities and scale layers are received by the flow guide hood 7, ensuring that all impurities are collected. The impurities enter the detachable dust collection box 72 through the dust discharge port 71 at the bottom of the flow guide hood 7, realizing the centralized collection of impurities. The detachable dust collection box 72 is easy to clean regularly to avoid the accumulation of impurities. The collected impurities are sent into the RTO regenerative thermal oxidizer 8 for high-temperature incineration through the bypass pipe 11 connected at the bottom, and through the coordinated control of the three-way fitting 12, the shut-off valve, the check valve and the three-way switching valve. The check valve can effectively prevent the backflow of combustion flue gas, and the three-way switching valve can flexibly switch the pipeline on and off, realizing the harmless and closed-loop treatment of impurities and avoiding secondary pollution. The high-concentration VOCs flue gas generated by desorption is sent into the RTO regenerative thermal oxidizer 8 through a dedicated pipeline to achieve complete decomposition of VOCs. The RTO regenerative thermal oxidizer 8 is equipped with a combustion chamber 81, a split regenerative array, an inspection door 83, a temperature partition 84, and a baffle 85. The combustion chamber 81 provides a closed space for the high-temperature combustion of VOCs, ensuring that the combustion temperature is stable above the decomposition threshold. The split-type thermal regenerator array consists of multiple independent, side-by-side thermal regenerator units 82, which can efficiently recover the high-temperature heat generated during incineration for subsequent waste gas preheating and desorption operations. Each thermal regenerator unit 82 is equipped with an independent maintenance door 83. When a single thermal regenerator unit 82 malfunctions or requires maintenance, the corresponding maintenance door 83 can be opened individually for online maintenance and replacement without the need for overall shutdown and furnace dismantling, significantly reducing downtime losses and maintenance costs of continuous production lines. The temperature partition 84 divides the interior of the combustion chamber 81 into a preheating zone, a main combustion zone, and a uniform temperature zone, allowing the waste gas to gradually heat up and ensuring sufficient decomposition of VOCs. The louvered baffles 85 installed in the uniform temperature zone are arranged at intervals along the height direction, which can effectively disrupt the airflow direction, balance the temperature and airflow distribution inside the furnace, avoid NOx exceeding the standard due to excessively high local temperatures, and prevent insufficient VOCs decomposition due to excessively low local temperatures, thereby improving incineration efficiency and environmental compliance rate. To achieve waste heat recovery and utilization and reduce system energy consumption, a waste heat utilization pathway 9 connecting the zeolite rotor 4 and the RTO regenerative thermal oxidizer 8 operates synchronously. This pathway includes a first flue gas duct 91 and a second flue gas duct 92. The first flue gas duct 91 connects the flue gas outlet of the RTO regenerative thermal oxidizer 8 to the desorption zone inlet of the zeolite rotor 4, transporting the high-temperature flue gas waste heat generated by RTO incineration to the desorption stage of the zeolite rotor 4, providing a stable heat source for VOCs desorption, ensuring desorption efficiency, and reducing additional energy consumption. The second flue gas duct 92 connects the RTO flue gas outlet to the air supply end of the blade-type air outlet array 5, using the high-temperature waste heat to heat the cleaning gas source, increasing the temperature of the cleaning airflow. Under low-temperature conditions, this effectively improves the removal effect of impurities and scale layers, further optimizing the unclogging performance. This dual-path waste heat utilization structure achieves cascaded utilization of waste heat, maximizing energy utilization and achieving energy-saving operation. To achieve intelligent collaborative control of the equipment, the dust sensor 10 works continuously to monitor the impurity accumulation status on the surface of the zeolite rotor 4 in real time. The detected impurity concentration, accumulation thickness, and other signals are transmitted to the PLC main control unit in real time. Based on the received monitoring signals, the PLC main control unit automatically analyzes and judges the degree of blockage of the zeolite rotor 4, and then adjusts the jet intensity and jet frequency of the blade-type air outlet array 5, as well as the vibration frequency of the ultrasonic vibrating plate 6, to achieve adaptive adjustment of the unblocking program. At the same time, the PLC main control unit also controls the operating temperature of the RTO regenerative thermal oxidizer 8, the rotation speed of the zeolite rotor 4, the on / off status of each valve, and the flue gas flow rate of the waste heat utilization passage 9 in real time, to achieve intelligent collaborative control of the entire equipment process, which greatly improves the stability of equipment operation and the reliability of treatment, and reduces manual operation intervention. After the waste gas treatment task is completed, the operator issues a shutdown command through the PLC main control unit. Under the precise control of the PLC main control unit, the equipment gradually reduces load, temperature, and speed according to the preset program: First, the waste gas intake is stopped and the relevant intake valves are closed; then, the RTO regenerative thermal oxidizer 8 enters the cooling program, gradually reducing the furnace temperature to avoid damage to the furnace body caused by sudden cooling; the zeolite rotor 4 gradually decelerates until it stops rotating; the blade-type air outlet array 5, ultrasonic vibrating plate 6, dust sensor 10 and other components stop working in sequence; finally, the PLC main control unit performs a shutdown self-check on the whole machine, and after confirming that all components have stopped safely, the entire shutdown process is completed. In summary, through the coordinated operation of its various components, the entire system achieves integrated treatment of low-temperature, high-viscosity VOCs waste gas, from source pretreatment, adsorption concentration, online sludge removal, to high-temperature incineration, waste heat recovery, and intelligent control. This solves many technical defects of existing technologies and ensures long-term stable, efficient, and energy-saving operation of the equipment.

This embodiment optimizes the structural parameters and flow characteristics of the de-adhesion component 2, enabling the component to have a more stable pretreatment capability under conditions of high air volume, high dust, and tar-containing exhaust gas. Without increasing the number of components or changing the overall system architecture, it effectively reduces the probability of impurities entering the zeolite rotor 4 and RTO heat storage body, extending the continuous operation cycle and maintenance-free period of the equipment. It is especially suitable for exhaust gas treatment scenarios that require long-term continuous operation, such as chemical industrial parks, large-scale coating production lines, and printing and coating workshops.

[0051] This embodiment achieves the above objectives through the following technical means: First, a porous mesh structure with high porosity, low wind resistance, and strong oleophobic adhesion properties is used as the oleophobic adhesive layer 22. This technology can quickly capture tar-like viscous impurities while maintaining stable system air pressure under high air volume conditions, reducing the entry of viscous substances into subsequent processes from the source. Second, a multi-layer gradient pore structure of the paint mist condensation mesh 23 is used to achieve graded and deep capture of dust particles and tar condensates, preventing fine impurities from penetrating and improving interception accuracy and dust holding capacity. Third, a flow-guiding permeable hole array is set on the separator plate 24. The uniform distribution rectification technology prevents impurities from escaping or clogging due to excessively high local wind speeds, ensuring a uniform and stable airflow field. The synergistic effect of the above technologies enables the de-adhesion component 2 to have a more stable pretreatment capability under high air volume, high dust, and tar-containing exhaust gas conditions, effectively reducing the probability of impurities entering the zeolite rotor 4 and RTO heat storage body, and extending the continuous operation cycle and maintenance-free period of the equipment.
