Description

Technical Field

[0001] This utility model relates to the field of zeolite rotor technology, and in particular to a waste heat recovery zeolite rotor catalytic combustion system. Background Technology

[0002] Waste heat recovery zeolite rotor catalytic combustion system is the mainstream equipment for industrial volatile organic compound (VOCs) treatment. It typically includes a rotor housing, a zeolite rotor, a desorption chamber, and a gas conveying assembly. After the waste gas to be treated enters the rotor housing, it completes VOCs adsorption and purification in the zeolite rotor adsorption zone. The adsorbed VOCs rotate with the rotor to the desorption chamber side, where they are desorbed at high temperature to form a high-concentration concentrated gas, which is then sent to the catalytic combustion unit for decomposition and treatment through the conveying channel.

[0003] In existing systems of this type, the adsorption zone and the desorption chamber are isolated by a single sealing structure. During long-term operation, the sealing structure is susceptible to the combined effects of high temperature in the desorption zone, VOCs corrosion, and wear from the rotating impeller, resulting in deformation, cracking, and other failures. This leads to cross-contamination between the adsorption and desorption zones, and the leaked high-concentration VOCs gas can easily mix into the purified gas, causing emissions to exceed standards, or dilute the desorbed concentrated gas, affecting the catalytic combustion efficiency. This seriously restricts the system's operational stability and environmental compliance. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a waste heat recovery zeolite rotor catalytic combustion system. The first drive drives the rotating table to switch the collection shell and the screw-installed cutter head for easy replacement. It eliminates the need for frequent manual replacement and calibration during machine shutdown, solving the problem of insufficient convenience and efficiency in size switching in the background technology. At the same time, the limiting component fixes the accessories and the collection shell collects waste materials, which also ensures the accuracy of the pressing hole and the cleanliness of the processing environment.

[0006] To achieve the above objectives, this utility model proposes a waste heat recovery zeolite rotor catalytic combustion system, comprising a rotor housing, a conveying port, a zeolite rotor, a desorption functional chamber, a protective inner plate, reinforcing heads, an isolation chamber, a monitoring component, and a conveying component. The conveying ports are respectively located on both sides of the rotor housing. An assembly base is fixedly connected to the inner wall of the rotor housing. The zeolite rotor is mounted on the inner wall of the assembly base. The desorption functional chamber is fixedly connected to one side of the assembly base and the zeolite rotor. A protective inner plate is fixedly connected to the interior of the desorption functional chamber relative to one side of the assembly base and the zeolite rotor. Multiple reinforcing heads are disposed between the inner wall of the desorption functional chamber and the outer wall of the protective inner plate, and are connected through these reinforcing heads. The space between the protective inner plate and the desorption functional chamber forms the isolation chamber. The monitoring component is installed inside the isolation chamber. The conveying component is installed on the top of the rotor housing.

[0007] This utility model discloses a waste heat recovery type zeolite rotor catalytic combustion system. The waste gas to be treated enters through a conveying port on one side of the rotor housing. After the zeolite rotor, which is stably supported by the mounting base, adsorbs VOCs, the purified gas is discharged from the conveying port on the other side. The adsorbed VOCs are desorbed in the desorption functional chamber to form a high-concentration concentrated gas, which is sent to the combustion unit through the gas conveying channel. The protective inner plate forms a closed isolation chamber with the desorption functional chamber through the reinforcing head. When the main seal fails, the leaked gas is confined in this chamber. The VOCs sensor fixed by the support head in the isolation chamber detects the concentration signal and transmits it to the controller. The controller starts the fan on the top of the rotor housing in conjunction with the controller. The leaked gas is extracted through the connecting pipe and connecting hose and sent back to the air inlet of the rotor housing for re-adsorption and treatment through the output pipe. Problem solved: The system achieves secondary physical isolation of leaked gas through an isolation chamber, real-time monitoring by VOCs sensors, rapid recovery and treatment by delivery components, and structural stability through reinforcement heads and mounting bases. This comprehensive approach, from isolation and monitoring to disposal, addresses the issue of cross-contamination caused by a single seal failure, preventing leaked gas from exceeding emission standards or diluting and desorbing concentrated gas, thus ensuring stable system operation and environmental compliance.

[0008] In addition, the waste heat recovery zeolite rotor catalytic combustion system proposed above according to this utility model may also have the following additional technical features: Specifically, the monitoring component includes a support head, a VOCs sensor, and a controller. The support head is fixedly connected to the inner wall of the isolation chamber, the VOCs sensor is mounted on the support head, and the controller is mounted on the top of the rotary box.

[0009] Specifically, the conveying assembly includes a fan, a connecting pipe, a connecting hose, and an output pipe. The fan is installed on the top of the impeller housing. One end of the connecting pipe penetrates the outer wall of the desorption functional cavity, and the other end of the connecting pipe penetrates the inner wall of the impeller housing. The connecting hose is provided between the input end of the fan and the other end of the connecting pipe, and the two ends are connected through the connecting hose. One end of the output pipe is connected to the output end of the fan, and the other end of the output pipe is fixedly connected to the air inlet side of the impeller housing.

[0010] Specifically, a gas delivery channel is installed on the side wall of the rotary box relative to the side of the desorption functional cavity.

[0011] Specifically, both the VOCs sensor and the fan are electrically connected to the controller, and the controller is electrically connected to an external power source.

[0012] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0015] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Rather, the embodiments of this utility model include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0016] The waste heat recovery zeolite rotor catalytic combustion system of this utility model is described below with reference to the accompanying drawings.

[0017] like Figures 1-4 As shown, the waste heat recovery zeolite rotor catalytic combustion system of this utility model embodiment may include a rotor housing 1, a conveying port 2, a zeolite rotor 3, a desorption functional cavity 4, a protective inner plate 5, a reinforcing head 6, an isolation cavity 7, a monitoring component 8, and a conveying component 9.

[0018] The conveying ports 2 are respectively opened on both sides of the rotary wheel housing 1. The inner wall of the rotary wheel housing 1 is fixedly connected to the mounting base 11. The zeolite rotary wheel 3 is installed on the inner wall of the mounting base 11. The desorption functional cavity 4 is fixedly connected to one side of the mounting base 11 and the zeolite rotary wheel 3. The interior of the desorption functional cavity 4 is fixedly connected to one side of the mounting base 11 and the zeolite rotary wheel 3. Multiple reinforcing heads 6 are provided between the inner wall of the desorption functional cavity 4 and the outer wall of the protective inner plate 5, and are connected to each other through the reinforcing heads 6.

[0019] It should be noted that the mounting base 11 described in this embodiment can be precisely matched with the installation structure of the zeolite rotor 3, ensuring that the zeolite rotor 3 remains stable during rotation and avoiding the expansion of the sealing gap due to vibration. The protective inner plate 5 is made of a material that is compatible with the working conditions of the desorption functional cavity 4, and can withstand the high temperature and VOCs corrosion in the desorption zone. The reinforcing heads 6 are evenly distributed around the circumference of the protective inner plate 5, which not only achieves a firm connection between the protective inner plate 5 and the inner wall of the desorption functional cavity 4, but also provides thermal deformation compensation space for the protective inner plate 5, preventing the protective inner plate 5 from warping or cracking under high temperature conditions, and ensuring the structural integrity of the isolation cavity 7.

[0020] The protective inner plate 5 and the desorption functional cavity 4 form an isolation cavity 7.

[0021] It should be noted that the isolation chamber 7 described in this embodiment is a closed cavity structure, which surrounds the core flow channel of the desorption functional cavity 4. It can fully cover the sealing boundary between the adsorption zone and the desorption zone, ensuring that no matter where the sealing failure occurs, the leaked gas can be quickly captured and confined within the isolation chamber 7, preventing the leaked gas from spreading to other functional areas. At the same time, the structural design of the isolation chamber 7 will not interfere with the normal airflow in the desorption functional cavity 4, and will not affect the VOCs desorption efficiency, thus achieving compatibility between secondary isolation and normal desorption functions.

[0022] The monitoring component 8 is installed inside the isolation chamber 7, and the conveying component 9 is installed on top of the rotary box 1.

[0023] It should be noted that the monitoring component 8 described in this embodiment is installed inside the isolation chamber 7, which can directly contact the leaked gas to ensure the authenticity and timeliness of the detection signal and avoid interference from the external environment on the monitoring results. The conveying component 9 is installed on the top of the rotary housing 1, which saves the horizontal installation space of the equipment and shortens the conveying path of the leaked gas. This allows the conveying component 9 to start quickly after receiving the monitoring signal and extract the leaked gas in the isolation chamber 7 in a timely manner. At the same time, this installation position will not interfere with other functional components inside the rotary housing 1, ensuring the smooth operation of the system as a whole and forming an efficient closed loop of "monitoring-response-processing".

[0024] Specifically, the waste gas to be treated enters the housing through the conveying port 2 on one side of the rotary housing 1. The mounting base 11 firmly supports the zeolite rotary wheel 3 and ensures its stability during rotation. During operation, the zeolite rotary wheel 3 completes the adsorption and purification of VOCs in the waste gas. The purified gas is discharged through the conveying port 2 on the other side. When the VOCs adsorbed by the zeolite rotary wheel 3 rotate to the desorption chamber 4, they undergo high-temperature desorption in the desorption chamber 4 to form a high-concentration concentrated gas. The protective inner plate 5 is firmly connected to the inner wall of the desorption chamber 4 through multiple circumferentially evenly distributed reinforcing heads 6, forming a closed isolation chamber 7 between the two. The reinforcing heads 6 also serve as the protective inner plate 5. It provides thermal deformation compensation space to prevent warping and cracking due to high temperature, ensuring the structural integrity of the isolation chamber 7. The isolation chamber 7 surrounds the core flow channel of the desorption functional chamber 4 and fully covers the sealing boundary between the adsorption and desorption zones. When the main sealing structure fails and gas leakage occurs, the leaked gas is quickly captured and confined within the isolation chamber 7. The monitoring component 8 installed inside the isolation chamber 7 directly contacts the leaked gas and detects the VOCs concentration signal in real time and accurately. The conveying component 9 installed on the top of the rotary box 1 starts quickly after receiving the signal from the monitoring component 8, and promptly extracts the leaked gas in the isolation chamber 7 and sends it back to the system for reprocessing, forming an efficient closed loop of "monitoring-response-processing". This system reduces the problem of sealing gap expansion caused by vibration of zeolite rotor 3 by mounting base 11, and achieves secondary physical isolation of gas leakage by using isolation chamber 7 formed by protective inner plate 5 and desorption functional chamber 4 to prevent leaked gas from spreading to other functional areas. Monitoring component 8 captures leakage signals in isolation chamber 7 in real time, and conveying component 9 promptly recovers and processes leaked gas. At the same time, reinforcement head 6 ensures the structural stability of protective inner plate 5 in high temperature and VOCs corrosive environment. The entire process of "reducing the causes of seal failure - secondary isolation of leaked gas - real-time monitoring - rapid processing" solves the gas leakage problem caused by the failure of a single sealing structure in the background technology, completely blocking the path of leaked gas to affect environmental emissions or dilute desorption and concentrate gas, and ensuring the stability of system operation and environmental compliance.

[0025] In one embodiment of this utility model, such as Figures 1-4 As shown, the monitoring component 8 includes a support head 81, a VOCs sensor 82, and a controller 83. The support head 81 is fixedly connected to the inner wall of the isolation chamber 7, the VOCs sensor 82 is mounted on the support head 81, and the controller 83 is mounted on the top of the rotary wheel housing 1.

[0026] It should be noted that the support head 81 described in this embodiment can be precisely adapted to the installation structure of the VOCs sensor 82, which not only ensures the stability of the VOCs sensor 82 in the isolation chamber 7, but also reduces the impact of equipment operation vibration on the sensor detection accuracy. At the same time, the support head 81 is made of high temperature resistant and corrosion resistant material, which can adapt to the complex working conditions in the isolation chamber 7 and avoid its own aging affecting the sensor fixing effect. The controller 83 is installed on the top of the rotary box 1, which not only facilitates operation and debugging by maintenance personnel, but also shortens the signal transmission path with the VOCs sensor 82 and improves the signal response speed.

[0027] Specifically, the support head 81 securely fixes the VOCs sensor 82 to the inner wall of the isolation chamber 7, ensuring that the VOCs sensor 82 is always in the area where leaked gas is prone to accumulate. This allows it to quickly detect abnormal changes in the VOCs concentration within the isolation chamber 7. The controller 83 establishes a stable connection with the VOCs sensor 82 via wires, receiving the concentration signal transmitted by the sensor in real time. This solves the problem in the prior art where cross-contamination could not be detected in time after a single seal failure, providing a reliable signal acquisition and processing basis for early warning of cross-contamination and preventing the spread of leaked gas from causing environmental violations or reduced combustion efficiency.

[0028] In one embodiment of this utility model, such as Figures 1-4 As shown, the conveying assembly 9 includes a fan 91, a connecting pipe 92, a connecting hose 93, and an output pipe 94. The fan 91 is installed on the top of the rotary wheel housing 1. One end of the connecting pipe 92 penetrates the outer wall of the desorption functional cavity 4, and the other end of the connecting pipe 92 penetrates the inner wall of the rotary wheel housing 1. A connecting hose 93 is provided between the input end of the fan 91 and the other end of the connecting pipe 92, and they are connected through the connecting hose 93. One end of the output pipe 94 is connected to the output end of the fan 91, and the other end of the output pipe 94 is fixedly connected to the air inlet side of the rotary wheel housing 1.

[0029] It should be noted that the connection between the connecting pipe 92 and the desorption functional cavity 4 described in this embodiment adopts a sealed structure design to prevent the leaked gas in the isolation cavity 7 from overflowing from the connection gap. The connecting hose 93 has good flexibility and sealing performance, which can compensate for the installation deviation between the fan 91 and the connecting pipe 92, and absorb the vibration during equipment operation to prevent the pipe connection from loosening and leaking. The outlet direction of the output pipe 94 is adapted to the airflow direction of the air inlet of the rotary box 1 to ensure that the recovered leaked gas can be smoothly merged into the waste gas to be treated without interfering with the adsorption process of the main airflow.

[0030] Specifically, when the controller 83 triggers a cross-gas warning, the fan 91 immediately starts and uses the connecting pipe 92 to generate negative pressure adsorption for the leaked gas in the isolation chamber 7. The connecting hose 93 ensures that there is no leakage during the airflow transmission. The leaked gas enters the fan 91 through the connecting pipe 92 and the connecting hose 93, and is then transported to the air inlet side of the rotor housing 1 through the output pipe 94, and re-enters the adsorption zone of the zeolite rotor 3 for treatment. This solves the problem in the background technology that cross-gas leaks cannot be effectively disposed of and are easy to diffuse to other areas. It realizes the recycling and reuse of leaked gas, which not only avoids exceeding environmental emission standards, but also prevents the desorbed concentrated gas from being diluted, thus ensuring the system's processing efficiency.

[0031] In one embodiment of this utility model, such as Figures 1-4 As shown, a gas delivery channel is installed on the side wall of the rotary box 1 relative to the side of the desorption functional cavity 4.

[0032] It should be noted that the gas delivery channel described in this embodiment is precisely aligned with the outlet position of the desorption functional chamber 4. The inner wall of the channel is treated with a smooth material to reduce the flow resistance of the high-concentration concentrated gas. At the same time, the channel has excellent sealing performance to prevent leakage of the concentrated gas during delivery. Furthermore, the installation position of the gas delivery channel avoids other functional components inside the rotor housing 1, so as not to affect the rotation of the zeolite rotor 3 and the structural stability of the protective inner plate 5, ensuring a smooth delivery path for the concentrated gas.

[0033] In one embodiment of this utility model, such as Figures 1-4 As shown, both the VOCs sensor 82 and the fan 91 are electrically connected to the controller 83, which is electrically connected to an external power supply.

[0034] It should be noted that the electrical connection between the VOCs sensor 82 and the controller 83 described in this embodiment uses shielded wires, which can effectively resist electromagnetic interference in the industrial environment and ensure the accuracy of concentration signal transmission. The electrical connection between the fan 91 and the controller 83 has overcurrent and overvoltage protection functions to prevent equipment damage caused by circuit failure. The connection between the controller 83 and the external power supply is stable and reliable, which can provide continuous power supply for the coordinated operation of the monitoring component 8 and the conveying component 9, and avoid the failure of the early warning and disposal functions due to power failure. In summary, in the waste heat recovery zeolite rotor catalytic combustion system of this utility model embodiment, the waste gas to be treated enters through the conveying port 2 on one side of the rotor housing 1. After the zeolite rotor 3, which is stably supported by the mounting base 11, adsorbs VOCs, the purified gas is discharged from the conveying port 2 on the other side. The adsorbed VOCs are desorbed in the desorption functional chamber 4 to form a high-concentration concentrated gas, which is sent to the combustion unit through the gas conveying channel. The protective inner plate 5 forms a closed isolation chamber 7 with the desorption functional chamber 4 through the reinforcing head 6. When the main seal fails, the leaked gas is confined in it. The VOCs sensor 82, which is fixed in the isolation chamber 7 by the support head 81, detects the concentration signal and transmits it to the controller 83. The controller 83 starts the fan 91 on the top of the rotor housing 1 in conjunction with the fan. The leaked gas is extracted through the connecting pipe 92 and the connecting hose 93 and sent back to the air inlet of the rotor housing 1 for re-adsorption and treatment through the output pipe 94. Problem solved: The leaked gas is physically isolated by the isolation chamber 7, the VOCs sensor 82 monitors it in real time, and the conveying component 9 quickly recovers and processes it. The reinforcement head 6 and the mounting base 11 ensure structural stability. The entire process of isolation, monitoring and disposal solves the problem of gas leakage caused by a single seal failure, avoids the leakage gas from causing excessive emissions or dilution and desorption of concentrated gas, and ensures the stable operation of the system and environmental compliance.
