Description

Technical Field

[0001] This utility model relates to the field of catalytic combustion technology, specifically a catalytic combustion device for treating organic waste gas. Background Technology

[0002] Catalytic combustion technology is a highly efficient end-of-pipe treatment technology. Essentially, catalytic combustion is a combustion reaction that occurs in combustible materials under specific temperature conditions with the aid of a catalyst. Compared to direct combustion, catalytic combustion has significant advantages: it can initiate the reaction at relatively low temperatures and promotes a more complete combustion process, greatly improving combustion efficiency and energy utilization. However, most catalysts cannot effectively prevent the accumulation of impurities on the catalyst support surface or in the pores of the catalyst layer. The exhaust gas contains a certain amount of dust and impurities, which easily accumulate on the support surface or in the pores over time, leading to blockage of the catalyst micropores and affecting the catalyst's performance.

[0003] For example, the prior art application number CN216346318U provides a catalytic combustion device for treating organic waste gas. It includes a shell, with a preheating chamber and a combustion chamber respectively opened at both ends of the shell, and the preheating chamber and the combustion chamber are connected. An installation port is opened on the side of the shell near the preheating chamber, and an inspection port is opened on the side of the shell near the combustion chamber. A support frame is installed inside the combustion chamber, and a fixed frame is connected to the top of the support frame. A grid is installed at both ends of the fixed frame, and a catalyst layer is set inside the fixed frame between the two grids. This utility model, through the cooperation of structures such as clamping rings, connecting rods and sliding columns, can make the two clamping rings press against the protective cylinder inward after the protective cylinder is inserted into the installation port, so as to firmly clamp and fix the protective cylinder, ensuring that the protective cylinder is stable at the installation port, preventing the protective cylinder from shaking, and greatly improving stability and safety.

[0004] Based on actual usage, the aforementioned prior art primarily prevents the protective cylinder from shaking and improves stability through the cooperation of structures such as clamping rings, connecting rods, and sliding columns. However, it has been found that it cannot effectively prevent the accumulation of impurities on the surface of the catalyst carrier or in the pores of the catalyst layer. The exhaust gas contains a certain amount of dust and impurities, which tend to accumulate on the surface or in the pores of the carrier over time, leading to blockage of the catalyst micropores and affecting the catalyst's performance. Therefore, based on actual usage, we have improved the aforementioned prior art. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of this section, the abstract and the title of this utility model. Such simplifications or omissions shall not be used to limit the scope of this utility model.

[0006] In view of the problems existing in the above and / or prior art, the present invention is proposed.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A catalytic combustion device for treating organic waste gas includes a base, a fan body, an air inlet, a combustion chamber, a sealed opening and closing door, an air outlet, a solenoid valve, and a catalyst carrier component to prevent impurity accumulation.

[0009] The base has a blower body on its top outer wall, an air inlet on one side of the blower body, a combustion chamber on one side of the base, a pipe at one end of the blower body at the top of the combustion chamber, an air outlet on one side of the top side wall of the combustion chamber, a solenoid valve on one side of the air outlet, a sealing door hinged at one end of the combustion chamber, and a catalyst carrier component to prevent impurity accumulation on the other side wall of the combustion chamber.

[0010] Furthermore, the catalyst carrier anti-impurity accumulation component includes a support shell disposed on the side wall of the other end of the combustion chamber. A motor is installed on the side wall of the partition plate inside the support shell. One end of the motor is rotatably connected to the outer side wall of the partition plate inside the support shell. An eccentric wheel connecting rod is disposed on the outer side wall of the motor's actuating end. A circular connecting rod is hinged to one end of the eccentric wheel connecting rod. A square short connecting rod is hinged to one end of the circular connecting rod. A driving rod is disposed at the bottom end of the square short connecting rod. One end of the driving rod is rotatably connected to the side wall of the partition plate inside the support shell. A first bearing is disposed on the outer wall of the other end of the driving rod. The first bearing is embedded in the side wall of the combustion chamber. The other end of the driving rod extends to the side wall of the combustion chamber. A catalyst carrier shell is disposed on the outer side wall of the other end of the driving rod. Multiple support plates with the same structure are disposed on the inner side wall of the catalyst carrier shell.

[0011] Furthermore: the combustion chamber includes a preheating chamber on one side of the inner cavity, a first burner body on the bottom of one side of the preheating chamber, and a vertical plate on the other side of the inner cavity of the preheating chamber. Multiple heat exchange tubes with the same structure are arrayed and embedded on both sides of the vertical plate, and a second burner body is provided on the side wall of the inner cavity of the combustion chamber adjacent to the other side of the preheating chamber.

[0012] Furthermore: the support plate includes a catalyst layer disposed on the inner sidewall.

[0013] Furthermore: the catalyst carrier shell includes matching fixing screws threaded to both outer side walls, and one end of each of the two sets of fixing screws is threaded to the side walls of the support plate.

[0014] Furthermore: the catalyst carrier shell includes a support vertical plate rotatably connected to one end of the outer side wall, and the top end of the support vertical plate is disposed on the top side wall of the combustion chamber cavity.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, through the catalyst carrier anti-impurity accumulation component, can effectively prevent the accumulation of impurities on the surface of the catalyst carrier or in the pores of the catalyst layer. Since the exhaust gas contains a certain amount of dust and impurities, this prevents these dust and impurities from accumulating on the surface or in the pores of the carrier over time, thus avoiding blockage of the catalyst micropores and affecting the catalyst's performance. Specifically, the operator allows the exhaust gas to enter the combustion chamber through the air inlet, including a preheating chamber located on one side of the inner cavity. The PLC controller triggers the preheating chamber's bottom side, where a first burner body (previously a technology) is located, to preheat the combustion chamber. This preheating is achieved through multiple heat exchange tubes of the same structure evenly arrayed on both sides of the vertical plate. Heat enters another compartment within the combustion chamber. A second burner body, located on the side wall of the compartment adjacent to the preheating chamber, performs heating operations. To effectively prevent the accumulation of impurities on the catalyst carrier surface or in the catalyst layer pores, the operator triggers the motor actuator via a PLC controller. This drives an eccentric wheel connecting rod located on one side of the outer wall to rotate, connected to the outer wall of the partition plate within the support shell for support rotation. One end of the eccentric wheel connecting rod is hinged to a circular connecting rod, which in turn drives a short square connecting rod to rotate. A driving rod is located at one end of the bottom of the short square connecting rod, with one end rotatably connected to the side wall of the partition plate within the support shell and the other end of the driving rod. The combustion chamber is equipped with a first bearing embedded in the inner wall of the combustion chamber for support and fixation. Because the eccentric wheel connecting rod on one side of the outer wall, driven by the trigger motor, has a small rotation radius, when the eccentric wheel connecting rod completes one revolution, it simultaneously causes a driving rod at the bottom of a square short connecting rod to perform an incomplete arc-shaped oscillation. This incomplete arc-shaped oscillation causes a supporting vertical plate on the other side of the outer wall, connected to the catalyst carrier shell via one side of the outer wall, to perform the same supporting arc-shaped oscillation. Since the exhaust gas may contain a certain amount of dust and impurities, the oscillation of the catalyst carrier shell reduces the accumulation of dust and impurities in the support plate, including the catalyst layer on the inner wall, by shaking, thus extending the service life of the catalyst layer. The above operations can effectively prevent the accumulation of impurities on the surface of the catalyst carrier shell or in the pores of the catalyst layer. Since the exhaust gas contains a certain amount of dust and impurities, this prevents these dust and impurities from accumulating on the surface or in the pores of the carrier over time, which would cause blockage of the catalyst micropores and affect the catalyst's performance. The organic exhaust gas after catalysis is discharged through a solenoid valve installed on one side wall of the outlet, which is triggered by a PLC controller. The operator can then manually open the sealing door hinged at one end of the combustion chamber. The catalyst carrier shell, including the outer side walls on both sides, is threaded with matching fixing screws that are also threaded to the side walls of the support plate, making it easy to disassemble the support plate and replace the new catalyst layer.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention.

Therefore, the present invention is not limited to the specific embodiments disclosed below.

When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0027] Furthermore, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Please see Figure 1-4 This utility model provides a technical solution: a catalytic combustion device for treating organic waste gas, including a base 1, a fan body 2, an air inlet 3, a combustion chamber 4, a sealed opening and closing door 5, an air outlet 6, a solenoid valve 7, and a catalyst carrier component 8 to prevent impurity accumulation.

[0029] A blower body 2 is installed on the top outer wall of the base 1. An air inlet 3 is connected to one side outer wall of the blower body 2, and a combustion chamber 4 is installed on one side outer wall of the base 1. A pipe at one end of the top of the blower body 2 is installed at the top of the inner cavity of the combustion chamber 4. An air outlet 6 is installed on one side top wall of the combustion chamber 4. A solenoid valve 7 is installed on one side wall of the air outlet 6. A sealing door 5 is hinged to one end of the combustion chamber 4. A catalyst carrier anti-impurity accumulation component 8 is installed on the other side wall of the combustion chamber 4. The catalyst carrier anti-impurity accumulation component 8 can effectively prevent the accumulation of impurities on the surface of the catalyst carrier or in the pores of the catalyst layer 881. Since the exhaust gas contains a certain amount of dust and impurities, this component can prevent these dust and impurities from accumulating on the surface or in the pores of the carrier over time, which would cause the micropores of the catalyst layer 881 to become blocked and affect the catalyst's performance.

[0030] Preferably, the catalyst carrier anti-impurity accumulation component 8 includes a support shell 81 disposed on the other side wall of the combustion chamber 4. A motor 82 is installed on the side wall of the partition plate inside the support shell 81. One end of the motor 82 is rotatably connected to the outer side wall of the partition plate inside the support shell 81. An eccentric wheel connecting rod 80 is disposed on the outer side wall of the motor 82's actuating end. A circular connecting rod 83 is hinged to one end of the eccentric wheel connecting rod 80. A square short connecting rod 84 is hinged to one end of the circular connecting rod 83. A driving round rod 85 is disposed at one bottom end of the square short connecting rod 84. One end of the driving round rod 85 is rotatably connected to the partition plate inside the support shell 81. The side wall, and the outer wall of the other end of the drive rod 85 is provided with a first bearing 86, which is embedded in the inner wall of the combustion chamber 4. The other end of the drive rod 85 extends to the inner wall of the combustion chamber 4, and the outer wall of the other end of the drive rod 85 is provided with a catalyst carrier shell 87. The inner wall of the catalyst carrier shell 87 is provided with multiple support plates 88 of the same structure. When effectively preventing the accumulation of impurities on the surface of the catalyst carrier or in the pores of the catalyst layer 881, the operator triggers the motor 82 to drive the eccentric wheel connecting rod 80 provided on one side of the outer wall through the PLC controller. The eccentric wheel connecting rod 80 is rotatably connected to the outer wall of the partition plate inside the support shell 81 for support and rotation. One end of the eccentric wheel connecting rod 80 is hinged to a circular connecting rod 83 for rotation. The rotation of the circular connecting rod 83 drives a square short connecting rod 84, which is hinged to one end, to rotate. Because one end of the square short connecting rod 84 is provided with a driving round rod 85, one end of which is rotatably connected to the side wall of the partition plate inside the support shell 81, and the other end of the driving round rod 85 is provided with a first bearing 86 embedded in the side wall of the combustion chamber 4 for support and fixation, the eccentric wheel connecting rod 80 on the outer wall of the trigger motor 82 has a small rotation radius. When the connecting rod 80 completes one revolution, it simultaneously causes the driving rod 85 at one end of the square short connecting rod 84 to swing in an incomplete arc. The driving rod 85 swings in an incomplete arc, causing the supporting vertical plate 872, which is rotatably connected to the outer wall of the catalyst carrier shell 87 at one end, to swing in the same supporting arc. This means that the exhaust gas may contain a certain amount of dust and impurities. When the catalyst carrier shell 87 swings, the support plate 88, including the catalyst layer 881 set on the inner wall, can reduce the accumulation of dust and impurities by shaking, thus extending the service life of the catalyst layer 881.

[0031] Preferably, the combustion chamber 4 includes a preheating chamber 41 disposed on one side of the inner cavity, a first burner body 42 disposed at the bottom of one side of the preheating chamber 41, and a vertical plate 43 disposed on the other side of the inner cavity of the preheating chamber 41. Multiple heat exchange tubes 44 of the same structure are arrayed and embedded on both sides of the vertical plate 43. A second burner body 45 is disposed on the side wall of the inner cavity of the combustion chamber 4 adjacent to the other side of the preheating chamber 41. Exhaust gas enters the combustion chamber 4 including the preheating chamber 41 disposed on one side of the inner cavity through the air inlet 3. The first burner body 42 disposed at the bottom of one side of the preheating chamber 41 is preheated by the PLC controller. The preheated gas enters the other side of the inner cavity of the combustion chamber 4 through the multiple heat exchange tubes 44 of the same structure arrayed on both sides of the vertical plate 43. The second burner body 45 disposed on the side wall of the inner cavity of the combustion chamber 4 adjacent to the other side of the preheating chamber 41 performs the heating operation.

[0032] Preferably, the support plate 88 includes a catalyst layer 881 disposed on the inner sidewall, and is threadedly connected to both sides of the support plate 88 by manually rotating the fixing screw 871, which facilitates the disassembly of the support plate 88 and replacement of the new catalyst layer 881.

[0033] Preferably, the catalyst carrier shell 87 includes matching fixing screws 871 threadedly connected to both outer side walls. One end of each of the two sets of fixing screws 871 is threadedly connected to the two side walls of the support plate 88. By manually rotating the catalyst carrier shell 87, the matching fixing screws 871 threadedly connected to both outer side walls of the support plate 88 are disengaged, making it easy to disassemble the support plate 88 and replace the new catalyst layer 881.

[0034] Preferably, the catalyst carrier shell 87 includes a support vertical plate 872 rotatably connected to one end of its outer wall. The top end of the support vertical plate 872 is disposed on the top side wall of the inner cavity of the combustion chamber 4, and is supported by the support vertical plate 872 rotatably connected to one end of its outer wall for arc-shaped swaying rotation.

[0035] Example: At the start of operation, the operator introduces exhaust gas into the combustion chamber 4 through the air inlet 3, including a preheating chamber 41 located on one side of the inner cavity. The PLC controller triggers a first burner body 42, a conventional technology located at the bottom of one side of the preheating chamber 41, for preheating. This preheating is achieved by multiple heat exchange tubes 44 of the same structure evenly embedded on both sides of the vertical plate 43, which then enter another compartment within the combustion chamber 4. A second burner body 45, located on the side wall adjacent to the preheating chamber 41, performs the heating operation. To effectively prevent the accumulation of impurities on the surface of the catalyst carrier or in the pores of the catalyst layer 881, the operator triggers the motor 82 via the PLC controller. The eccentric wheel connecting rod 80, located on one side of the outer wall of the motor 82, rotates at one end and is connected to the outer wall of the partition plate inside the support housing 81 for support and rotation. A circular connecting rod 83 is hinged to one end of the eccentric wheel connecting rod 80, causing it to rotate. The rotation of the circular connecting rod 83 drives a square short connecting rod 84, which is hinged to one end of the square short connecting rod 84. A driving rod 85 is located at one end of the bottom of the square short connecting rod 84, which is rotatably connected to the side wall of the partition plate inside the support housing 81. A first bearing 86 is located on the outer wall of the other end of the driving rod 85 and is embedded in the side wall of the combustion chamber 4 for support and fixation. Because the radius of rotation of the eccentric wheel connecting rod 80, located on one side of the outer wall of the motor 82, is small, when the eccentric wheel... When the connecting rod 80 completes one revolution, it simultaneously causes the driving rod 85 at one end of the square short connecting rod 84 to perform an incomplete arc-shaped oscillation. This incomplete arc-shaped oscillation of the driving rod 85 causes the supporting vertical plate 872, which is rotatably connected to the catalyst carrier shell 87 on one end of its outer wall, to perform the same supporting arc-shaped oscillation. This allows the catalyst carrier shell 87, which may contain a certain amount of dust and impurities in the exhaust gas, to reduce the accumulation of dust and impurities in the supporting plate 88, including the catalyst layer 881 located on its inner wall, by shaking. This extends the service life of the catalyst layer 881. Through the above operation, the surface of the catalyst carrier shell 87 or the pores of the catalyst layer 881 can be cleaned. To effectively prevent the accumulation of impurities, since the exhaust gas contains a certain amount of dust and impurities, this method avoids the accumulation of these dust and impurities on the surface or in the pores of the carrier over time, which would cause blockage of the catalyst micropores and affect the catalyst's performance. The catalytically catalyzed organic waste gas is discharged through a solenoid valve 7 installed on one side wall of the outlet 6, which is triggered by a PLC controller. Then, the operator can manually open the combustion chamber 4, which is hinged to a sealing door 5. By manually rotating the catalyst carrier shell 87, which includes matching fixing screws 871 threaded to both outer side walls, and the screws 871 threaded to both side walls of the support plate 88, it is easy to disassemble the support plate 88 and replace the new catalyst layer 881.

[0036] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
