Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment equipment technology, and in particular to a high-efficiency catalytic combustion waste gas treatment device. Background Technology

[0002] Exhaust gases contain a large amount of volatile organic compounds and other harmful substances, which not only damage the atmospheric environment but also harm human health. Catalytic combustion, as an effective method for treating exhaust gases, uses a catalyst to lower the combustion temperature of harmful substances in the exhaust gas, allowing them to burn and decompose completely at a lower temperature, transforming them into harmless carbon dioxide and water.

[0003] In practical applications, honeycomb catalysts face various factors that lead to a decrease in activity over time. Impurities in the exhaust gas, such as dust and heavy metals, gradually adsorb onto the catalyst surface, clogging its pore structure and hindering contact between the exhaust gas and the catalyst's active sites, thereby reducing catalytic efficiency. Furthermore, it is difficult to clear the pores, and catalyst disassembly and assembly are cumbersome, making catalyst replacement inconvenient. Therefore, we propose a high-efficiency catalytic combustion exhaust gas treatment device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a highly efficient catalytic combustion waste gas treatment device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-efficiency catalytic combustion waste gas treatment device includes a catalytic combustion chamber. An inlet pipe is installed on one side of the catalytic combustion chamber, and an outlet pipe is installed on the other side. A heater is installed on the bottom inner wall of the catalytic combustion chamber. Two support seats are installed on the front and rear inner walls of the catalytic combustion chamber. A frame plate is placed on the top of the two support seats, and a catalyst is installed inside the frame plate. Multiple through holes are equally spaced on the catalyst. A partition plate is fixedly installed inside the catalytic combustion chamber. Multiple guide holes are equally spaced on the partition plate. The same lifting plate is slidably installed on the inner walls of both sides of the catalytic combustion chamber. Multiple insertion rods are equally spaced on the bottom of the lifting plate, and the insertion rods are adapted to the corresponding through holes.

[0007] Preferably, a temperature sensor is installed on one inner wall of the catalytic combustion chamber, and a controller is installed on the front side of the catalytic combustion chamber, with the temperature sensor and the controller being electrically connected.

[0008] Preferably, an installation hole is provided on one side of the inner wall of the catalytic combustion chamber, and a T-shaped sealing seat is installed on one side of the frame plate, and the T-shaped sealing seat is adapted to the installation hole.

[0009] Preferably, a plurality of fixing screws are installed on one side of the catalytic combustion chamber, and a plurality of insertion holes are provided on the T-shaped sealing seat, with the fixing screws passing through the corresponding insertion holes and being threaded with fixing nuts.

[0010] Preferably, two threaded rods are rotatably mounted on the top of the partition, and the lifting plate is threaded onto the two threaded rods.

[0011] Preferably, a housing is fixedly installed on the top of the catalytic combustion chamber, and the top end of the threaded rod extends into the housing.

[0012] Preferably, a rotating shaft is rotatably mounted on the inner walls of both sides of the housing, and a drive motor is fixedly mounted on one side of the housing, with the output shaft of the drive motor fixedly connected to the rotating shaft.

[0013] Preferably, two driving bevel gears are fixedly installed on the rotating shaft, and a driven bevel gear is installed at the top of the threaded rod, with the driving bevel gear meshing with the corresponding driven bevel gear.

[0014] The beneficial effects of this utility model are:

[0015] 1. When the exhaust gas enters the catalytic combustion chamber, it undergoes a combustion reaction under the action of the catalyst. The temperature sensor monitors the temperature inside the catalytic combustion chamber in real time. When the temperature is lower than the set value, the controller starts the heating device to heat the catalytic combustion chamber. The catalyst with multiple through holes set at equal intervals greatly improves the contact effect between the exhaust gas and the catalyst, thereby significantly improving the combustion efficiency and enabling the harmful substances in the exhaust gas to be decomposed more fully.

[0016] 2. Through the cooperation of the drive motor, rotating shaft, drive bevel gear and driven bevel gear, the rotating shaft can drive the two threaded rods to rotate. The rotation of the threaded rods can drive the lifting plate and the insert rod to move downward. The insert rod can penetrate the through hole of the catalyst, which can clear the through hole and prevent impurities that may be contained in the exhaust gas from being gradually adsorbed on the catalyst surface and blocking its through hole.

[0017] 3. By rotating the fixing nut, the fixing nut is separated from the fixing screw, which releases the T-shaped sealing seat. The catalyst can then be removed from the catalytic combustion chamber through the T-shaped sealing seat, making it easy to disassemble and replace the catalyst. Attached Figure Description

Detailed Implementation

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0025] This application discloses a high-efficiency catalytic combustion waste gas treatment device.

[0026] Reference Figure 1-5 A high-efficiency catalytic combustion waste gas treatment device includes a catalytic combustion chamber 101, an inlet pipe 102 installed on one side of the catalytic combustion chamber 101, an outlet pipe 103 installed on the other side of the catalytic combustion chamber 101, a heater 201 installed on the bottom inner wall of the catalytic combustion chamber 101, two support seats 203 installed on the front and rear inner walls of the catalytic combustion chamber 101, a frame plate 204 placed on the top of the two support seats 203, a catalyst 205 installed inside the frame plate 204, a plurality of through holes 206 equally spaced on the catalyst 205, a partition plate 401 fixedly installed inside the catalytic combustion chamber 101, a plurality of guide holes 402 equally spaced on the partition plate 401, and a same lifting plate 403 slidably installed on the inner walls of both sides of the catalytic combustion chamber 101, a plurality of insert rods 404 equally spaced on the bottom of the lifting plate 403, the insert rods 404 being adapted to the corresponding through holes 206.

[0027] In this embodiment, a temperature sensor 202 is installed on one inner wall of the catalytic combustion chamber 101, and a controller 207 is installed on the front side of the catalytic combustion chamber 101, with the temperature sensor 202 and the controller 207 electrically connected. This allows for automatic temperature control based on real-time temperature within the catalytic combustion chamber 101, maintaining a stable reaction environment and ensuring that the catalytic combustion reaction proceeds efficiently within a suitable temperature range, thus greatly improving the waste gas treatment effect and stability.

[0028] In this embodiment, an installation hole 301 is provided on one inner wall of the catalytic combustion chamber 101, and a T-shaped sealing seat 302 is installed on one side of the frame plate 204, with the T-shaped sealing seat 302 fitting into the installation hole 301. Multiple fixing screws 304 are installed on one side of the catalytic combustion chamber 101, and multiple insertion holes 303 are provided on the T-shaped sealing seat 302. The fixing screws 304 pass through the corresponding insertion holes 303 and are threaded with fixing nuts 305. This makes the installation and disassembly of the catalyst 205 simple and quick, facilitating the replacement or maintenance of the catalyst 205.

[0029] In this embodiment, two threaded rods 501 are rotatably mounted on the top of the partition plate 401, and the lifting plate 403 is threadedly sleeved on the two threaded rods 501. This structural design utilizes the threaded engagement between the threaded rods 501 and the lifting plate 403 to precisely and smoothly control the lifting action of the lifting plate 403, providing a stable and reliable power transmission for the subsequent unblocking operation of the insertion rod 404 through the catalyst 205 through hole 206, ensuring that the unblocking work is carried out efficiently and orderly.

[0030] In this embodiment, a housing 601 is fixedly installed on the top of the catalytic combustion chamber 101, and the top end of the threaded rod 501 extends into the housing 601. Rotating shafts 602 are rotatably installed on the inner walls of both sides of the housing 601. A drive motor 603 is fixedly installed on one side of the housing 601, and the output shaft of the drive motor 603 is fixedly connected to the rotating shaft 602. Two drive bevel gears 604 are fixedly installed on the rotating shaft 602, and a driven bevel gear 605 is installed on the top end of the threaded rod 501. The drive bevel gears 604 mesh with the corresponding driven bevel gears 605. The drive motor 603 can efficiently and synchronously drive the two threaded rods 501 to rotate through a series of transmission components, thereby achieving precise control of the lifting plate 403 and effectively improving the automation and efficiency of the unblocking operation of the catalyst 205 through hole 206.

[0031] In this invention, when exhaust gas enters the catalytic combustion chamber 101, it undergoes combustion under the action of the catalyst 205. A temperature sensor 202 monitors the temperature inside the catalytic combustion chamber 101 in real time. When the temperature falls below a set value, the controller 207 activates the heating device to heat the catalytic combustion chamber 101. The catalyst 205 with multiple equally spaced through-holes 206 significantly improves the contact effect between the exhaust gas and the catalyst 205, thereby significantly improving combustion efficiency and allowing for more complete decomposition of harmful substances in the exhaust gas. By starting the drive motor 603, the drive motor 603 drives the rotating shaft 602 to rotate. Through the cooperation of the drive bevel gear 604 and the driven bevel gear 605, the rotating shaft 602 drives the two threaded rods 501 to rotate. The rotation of the threaded rod 501 can cause the lifting plate 403 and the insertion rod 404 to move downwards. The insertion rod 404 can penetrate the through hole 206 of the catalyst 205, which can clear the through hole 206 and prevent impurities that may be contained in the exhaust gas from gradually adsorbing onto the surface of the catalyst 205 and clogging the through hole 206. By rotating the fixing nut 305, the fixing nut 305 is separated from the fixing screw 304, which can release the fixation of the T-shaped sealing seat 302. The catalyst 205 can be moved out of the catalytic combustion chamber 101 through the T-shaped sealing seat 302, which can facilitate the disassembly and replacement of the catalyst 205.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
