Description

Technical Field

[0001] This utility model belongs to the field of catalytic combustion technology, specifically, it relates to a high-efficiency and energy-saving catalytic combustion device. Background Technology

[0002] Catalytic combustion equipment is an environmentally friendly device used to treat volatile organic compounds and harmful gases. It uses a catalyst to oxidize and decompose pollutants into carbon dioxide and water at a relatively low temperature.

[0003] The utility model disclosed in CN219735338U is a catalytic combustion device that is easy to maintain. The catalytic plate is slidably inserted into the interior of the catalytic combustion chamber through a slide rail and handle. With the cooperation of the fixing mechanism, the catalytic plate can be easily installed and disassembled, which can improve the replacement efficiency of the catalyst block inside the catalytic plate. However, the machine needs to be stopped when replacing the catalytic plate, which will interrupt the catalysis of the exhaust gas and greatly reduce the working efficiency. Therefore, we propose a high-efficiency and energy-saving catalytic combustion device. Utility Model Content

[0004] This invention provides a highly efficient and energy-saving catalytic combustion device to solve the technical problems mentioned in the background section.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A high-efficiency and energy-saving catalytic combustion device includes several vertically equidistant ports at the front end of a catalytic combustion chamber. Each port is connected to the interior of the chamber. A fixed frame is movably and sealed within each port. A catalyst grid plate is detachably installed inside each fixed frame, and the catalyst grid plate is filled with catalyst. The left and right side walls of the fixed frame are respectively slidably and sealed to the inner wall of the catalytic combustion chamber. A sealing plate abuts against the rear side of each fixed frame, and the left and right sides of the sealing plate are slidably and sealed to the inner wall of the catalytic combustion chamber. A sliding rod is fixedly connected to the left and right ends of each sealing plate, and the sliding rod slides through the catalytic combustion chamber. The rear sidewall of the chamber is fixedly connected to a rectangular plate. A compression spring is coaxially sleeved on the slide rod. The two ends of the compression spring are fixedly connected to the rectangular plate and the sidewall of the catalytic combustion chamber, respectively. The sealing plate is always in sealed contact with the fixed frame under the action of the compression spring. The fixed frame is completely inserted into the interior of the catalytic combustion chamber. The top of the fixed frame is sealed against the rear sidewall of the interior of the catalytic combustion chamber. A fixed plate is fixedly installed at the front end of the fixed frame. The fixed plate is detachably connected to the front sidewall of the catalytic combustion chamber. An air intake pipe is fixedly connected to the sidewall of the catalytic combustion chamber. A burner is embedded in the bottom of the catalytic combustion chamber. An exhaust pipe is fixedly connected to the top of the catalytic combustion chamber.

[0007] Furthermore, the inner sidewall of the fixing frame is provided with an annular mounting groove, and the rear end of the fixing frame has an opening for inserting a catalyst grid plate, the opening being in communication with the annular mounting groove.

[0008] Furthermore, threaded holes are provided at the four corners of the fixed frame, and screws are threaded into the threaded holes. An extrusion plate is coaxially fixed to the bottom of the screw, and the extrusion plate abuts against the top of the catalyst grid plate.

[0009] Furthermore, through holes are provided at the four corners of the fixing plate, and fixing bolts that are threaded to the front of the catalytic combustion chamber are inserted into the through holes.

[0010] Furthermore, an induced draft fan is fixedly installed on the right side wall of the catalytic combustion chamber, and an induced draft pipe is fixedly connected to the suction end of the induced draft fan, and the induced draft pipe is fixedly connected to the exhaust pipe.

[0011] The technological advancements achieved by this invention compared to existing technologies, due to the aforementioned structure, are as follows: This invention delivers organic waste gas to the catalytic combustion chamber via an inlet pipe. Upon starting the burner, the waste gas undergoes flameless combustion during emission. The combusted organic waste gas comes into contact with the catalyst within each catalyst grid plate and is catalyzed, causing the harmful substances in the organic waste gas to be completely converted into harmless substances under flameless and low-temperature conditions. The harmless gas is then discharged through the exhaust pipe. When it is necessary to replace the catalyst within one of the catalyst grid plates, the fixing frame and the catalyst grid plate are pulled out. During this process, under the action of a compression spring, the sliding rod moves the sealing plate forward, and the sealing plate remains in sealed contact with the fixing frame. When the fixing frame is completely pulled out, the sealing plate seals and blocks the insertion port, making catalyst replacement more convenient without requiring machine shutdown and without interrupting the catalysis of the waste gas, greatly improving work efficiency. After the fixing frame is pulled out, the catalyst grid plate can be replaced. Attached Figure Description

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] This utility model discloses a high-efficiency and energy-saving catalytic combustion device, such as Figure 1-5 As shown, the catalytic combustion chamber 1 includes multiple slots equidistantly spaced vertically at its front end. These slots are connected to the interior of the chamber. A fixed frame 2 is movably and sealed within each slot. A catalyst mesh plate 3 is detachably installed inside the fixed frame 2, and the catalyst mesh plate 3 is filled with catalyst. The left and right side walls of the fixed frame 2 are respectively slidably and sealed to the inner wall of the catalytic combustion chamber 1. A sealing plate 4 abuts against the rear side of each fixed frame 2. The left and right sides of the sealing plate 4 are respectively slidably and sealed to the inner wall of the catalytic combustion chamber 1. A sliding rod 5 is fixedly connected to both ends of each sealing plate 4. The sliding rod 5 slides through the rear wall of the catalytic combustion chamber 1 and is perpendicular to the rectangular... The rectangular plate 6 is fixedly connected, and the slide rod 5 is coaxially sleeved with a compression spring 7. The two ends of the compression spring 7 are fixedly connected to the rectangular plate 6 and the side wall of the catalytic combustion chamber 1, respectively. Under the action of the compression spring 7, the sealing plate 4 is always sealed and abutting against the fixed frame 2. The fixed frame 2 is completely inserted into the inside of the catalytic combustion chamber 1. The top of the fixed frame 2 is sealed and abutting against the rear side wall inside the catalytic combustion chamber 1 with the sealing plate 4. The front end of the fixed frame 2 is fixedly installed with a fixed plate 8. The fixed plate 8 and the front side wall of the catalytic combustion chamber 1 are detachably connected. The side wall of the catalytic combustion chamber 1 is fixedly connected with an air intake pipe 9. The bottom of the catalytic combustion chamber 1 is embedded with a burner 10. The top of the catalytic combustion chamber 1 is fixedly connected with an exhaust pipe 11.

[0022] The working principle and advantages of this utility model are as follows: Organic waste gas is transported to the catalytic combustion chamber 1 through the air inlet pipe 9. The burner 10 is started, and the waste gas is flamelessly burned when it is sprayed out. After combustion, the organic waste gas comes into contact with the catalyst in each catalyst grid plate 3 and is catalyzed, so that the organic waste gas completely turns the harmful substances into harmless substances under flameless and low temperature conditions. The harmless gas is discharged through the exhaust pipe 11. When it is necessary to replace the catalyst inside one of the catalyst grid plates 3, the fixing frame 2 and the catalyst grid plate 3 are pulled out. During this process, under the action of the compression spring 7, the slide rod 5 drives the sealing plate 4 to move forward, and the sealing plate 4 is always sealed and abutting against the fixing frame 2. When the fixing frame 2 is completely pulled out, the sealing plate 4 seals and blocks the inlet, making it more convenient to replace the catalyst without stopping the machine and without interrupting the catalysis of the waste gas, which greatly improves the working efficiency. After the fixing frame 2 is pulled out, the catalyst grid plate 3 is replaced.

[0023] In a preferred embodiment of this utility model, an annular mounting groove 12 is provided around the inner sidewall of the fixing frame 2, and an opening 13 is provided through the rear end of the fixing frame 2 for inserting the catalyst grid plate 3. The opening 13 and the annular mounting groove 12 are connected through the opening. Threaded holes are provided at the four corners of the fixing frame 2, and screws 14 are threadedly connected to the threaded holes. An extrusion plate 15 is coaxially fixedly connected to the bottom of the screw 14, and the extrusion plate 15 abuts against the top of the catalyst grid plate 3. In this embodiment, the catalyst grid plate 3 is inserted into the annular mounting groove 12 through the opening 13, and then the screw 14 is rotated and moved downward, so that the extrusion plate 15 extrudes and fixes the four corners of the catalyst grid plate 3. This embodiment facilitates the replacement of the catalyst grid plate 3 and can fix catalyst grid plates 3 of different thicknesses.

[0024] In a preferred embodiment of this utility model, through holes are provided at the four corners of the fixing plate 8, and fixing bolts 16 are inserted into the through holes. The fixing bolts 16 are threadedly connected to the front side of the catalytic combustion box 1.

[0025] In a preferred embodiment of the present invention, an induced draft fan 17 is fixedly installed on the right side wall of the catalytic combustion chamber 1.
