Abstract
Description
Technical Field
[0001] This utility model relates to the field of exhaust gas processors, and in particular to a catalytic exhaust gas processor. Background Technology
[0002] Catalytic oxidation is a technology that uses catalysts to reduce the activation energy of the oxidation reaction of organic matter in waste gas, thereby achieving efficient combustion at a lower temperature. This technology is widely used in industrial waste gas treatment, especially in the treatment of volatile organic compounds. When the waste gas enters the catalytic treatment equipment, it needs to be sprayed with a tower and filtered to remove particulate matter. Although most of the particulate matter can be removed, carbon buildup and clogging can still occur after long-term use.
[0003] Blocked catalytic burners need to be cleaned, but existing cleaning methods involve manually cleaning the internal heat storage ceramics, which is inefficient and results in a long downtime for the catalytic equipment. In addition, cleaning is usually only started when the blockage is severe, and the efficiency of exhaust gas catalytic treatment is already significantly reduced before cleaning.
[0004] Therefore, a catalytic exhaust gas processor is provided. Utility Model Content
[0005] In view of the problems existing in the prior art, the present invention is proposed.
[0006] Therefore, the present invention aims to solve the technical problem that existing cleaning methods rely on manual cleaning of the internal heat storage ceramics, which is inefficient.
[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a catalytic exhaust gas processor, comprising a catalytic treatment component, an exhaust gas blower component installed on one side of the catalytic treatment component, and a hot air component installed on the top of the catalytic treatment component; The catalytic treatment assembly includes a combustion chamber, at the bottom of which a catalytic furnace and a regenerative furnace are respectively provided. Support feet are respectively installed on the outer side of the bottom of the catalytic furnace and the regenerative furnace. An exhaust pipe is installed at the center of the bottom of the catalytic furnace, and a straight discharge pipe is installed at the bottom of the regenerative furnace. The exhaust gas blower assembly includes a mounting frame, on the top of which an exhaust gas blower is mounted. An exhaust gas duct is installed at the outlet of the exhaust gas blower, and one end of the exhaust gas duct is fixed to and connected to the discharge straight pipe. The hot air assembly includes an air inlet structure, which is installed on the top of the combustion chamber. A hot air structure is installed on the outer wall of the air inlet structure. An air intake blower is installed at the air inlet of the hot air structure, and a filter structure is installed at the air inlet of the air intake blower.
[0008] In a preferred embodiment of the catalytic exhaust gas processor described in this utility model, the air inlet structure includes an inlet pipe that is connected to the combustion chamber, and an on / off valve is provided on the inlet pipe.
[0009] In a preferred embodiment of the catalytic exhaust gas processor of this utility model, the hot air structure includes an insulated chamber, the air outlet of the insulated chamber is connected to the feed pipe, and the air inlet of the feed pipe is connected to the air outlet of the air blower.
[0010] In a preferred embodiment of the catalytic exhaust gas processor described in this utility model, two sets of brackets are installed on the inner walls on both sides of the heat preservation chamber, and heating wires are installed between the brackets.
[0011] In a preferred embodiment of the catalytic exhaust gas processor described in this utility model, the filtration structure includes a filter box, which is installed at the air inlet of the air blower, and a filter element is fixedly installed inside the filter box.
[0012] In a preferred embodiment of the catalytic exhaust gas processor of this utility model, an installation frame is installed at one end of the air inlet of the filter box, the installation frame is connected to the filter box, and one end of the installation frame is covered with a dustproof cloth.
[0013] In a preferred embodiment of the catalytic exhaust gas processor of this utility model, the separation component includes a mounting bracket, which is installed at the top center of the inner wall of the combustion chamber.

[0014] In a preferred embodiment of the catalytic exhaust gas processor of this utility model, the separation component further includes a drive motor, which is fixedly installed on the top of the combustion chamber, and the rotor of the drive motor meshes with a driven gear through a gear.
[0015] The beneficial effects of this utility model are as follows: The feed pipe allows cleaning fluid to be injected into the interior, removing internal carbon deposits. The cleaned fluid then passes through the heat storage ceramic and exits through the straight discharge pipe. This type of pipe does not affect the normal flow of exhaust gas and avoids the problem of cleaning fluid entering the exhaust gas pipe. The included hot air assembly can be used to reverse-heat and pressurize the internal carbon deposits, causing them to fall off and be discharged through the straight discharge pipe. This is suitable for addressing mild carbon buildup and blockage in the catalytic heat storage ceramic, increasing the service life of the catalytic equipment. After cleaning with the cleaning fluid, the hot air assembly can also be used to dry the internal catalytic equipment, preventing cleaning fluid residue. Attached Figure Description

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0020] Secondly, this utility model is described in detail with reference to the schematic diagrams. 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.
[0021] 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. Example 1
[0022] Reference Figure 1-4 This embodiment provides a catalytic exhaust gas processor, including a catalytic treatment component 100, an exhaust gas blower component 200 installed on one side of the catalytic treatment component 100, and a hot air component 300 installed on the top of the catalytic treatment component 100. The hot air component 300 can heat the internal catalytic treatment component 100 and blow out gas to remove some of the accumulated carbon deposits. The catalytic treatment assembly 100 includes a combustion chamber 101, which is the main body of the catalytic waste gas treatment. A catalytic furnace 102 and a regenerator 104 are respectively installed at the bottom of the combustion chamber 101. The catalytic furnace 102 and the regenerator 104 are different functional devices. Support feet 105 are respectively installed on the outer side of the bottom of the catalytic furnace 102 and the regenerator 104. The support feet 105 support and fix the device to increase the stability of the device installation. An exhaust pipe 103 is installed at the center of the bottom of the catalytic furnace 102. The exhaust pipe 103 is connected to the catalytic furnace 102 to discharge the treated waste gas and reduce the processing pressure of subsequent equipment. A discharge straight pipe 106 is installed at the bottom of the regenerator 104. The discharge straight pipe 106 can be used to discharge carbon deposits in the device. The exhaust gas blower assembly 200 includes a mounting frame 201, which is used to install and fix the top mounting frame 201. An exhaust gas blower 202 is placed on the top of the mounting frame 201. The exhaust gas blower 202 can transport exhaust gas to the regenerator 104. An exhaust gas duct 203 is installed at the outlet of the exhaust gas blower 202. One end of the exhaust gas duct 203 is fixed to and connected to the discharge straight pipe 106. A three-way valve is provided at the connection between the exhaust gas duct 203 and the discharge straight pipe 106, which can be used to control the passage between the discharge straight pipe 106 and the exhaust gas duct 203 to meet different needs. The hot air assembly 300 includes an air inlet structure 301, which includes a feed pipe 301a. The feed pipe 301a has a straight cylindrical design to facilitate the pouring of cleaning fluid, allowing it to enter the bottom regenerator 104 and preventing it from entering other equipment. The feed pipe 301a is connected to the combustion chamber 101. A switch valve 301b is installed on the feed pipe 301a, allowing personnel to easily open the feed pipe 301a and close it during normal use to prevent debris from falling in. The air inlet structure 301 is installed at the top of the combustion chamber 101. A hot air structure 302 is installed on the outer wall of the air inlet structure 301. The hot air structure 302 has an electric heating wire inside, which can heat the gas generated by the device to make it a high-temperature gas. An air inlet blower 303 is installed at the air inlet of the hot air structure 302. The air inlet blower 303 inputs gas into the hot air structure 302. A filter structure 304 is installed at the air inlet of the air inlet blower 303. The filter structure 304 effectively removes dust from the air and filters the gas entering the device, preventing large particles of dust and other debris from entering the device and causing dust blockage.
[0023] This embodiment has the following workflow: When the regenerator 104 needs internal cleaning, the air intake blower 303 is turned on to supply clean air to the hot air structure 302. After the air enters, it is heated by the heating wire inside the hot air structure 302. Once heated, the air enters the regenerator 104, achieving reverse airflow from the top of the regenerator 104. This reverse airflow blows away dust clogging the holes in the regenerator 104, causing it to fall into the discharge straight pipe 106. Opening the three-way valve on the discharge straight pipe 106 allows the dust to fall out. For blockages such as carbon deposits, when the blockage is severe, the cleaning fluid can be manually injected into the feed pipe 301a by opening the switch valve 301b. The fluid will then fall from the feed pipe 301a into the regenerator 104. After soaking for a period of time, the cleaning fluid will carry away impurities and fall into the discharge straight pipe 106. Opening the three-way valve on the discharge straight pipe 106 will allow the carbon deposits and cleaning fluid to fall off. Then, the air inlet blower 303 will be turned on to input clean, high-temperature gas into the hot air structure 302 to dry the cleaning fluid in the regenerator 104, preventing moisture from affecting the use of the device. Example 2
[0024] Reference Figure 5-6 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs from the previous embodiment in that it provides a catalytic exhaust gas processor, comprising: The hot air structure 302 includes an insulation chamber 302a. The air outlet of the insulation chamber 302a is connected to the inlet pipe 301a, and the air inlet of the inlet pipe 301a is connected to the air outlet of the air blower 303. Two sets of brackets 302b are installed on the inner walls on both sides of the insulation chamber 302a. Each set of brackets 302b has three brackets. The brackets 302b are used to install heating wires 302c for easy fixation. Heating wires 302c are installed between the brackets 302b. The heating wires 302c can generate high temperature. When air flows through them, some heat is carried away. Their curved shape greatly increases the contact area with air. The filter structure 3... 04 includes a filter box 304a, which is installed at the air inlet of the air blower 303. A filter element 304d is fixedly installed inside the filter box 304a. The filter element 304d uses activated carbon and other filtration equipment to filter small particles in the air. An installation frame 304b is installed at one end of the air inlet of the filter box 304a. The installation frame 304b fixes the dustproof cloth 304c. The installation frame 304b is connected to the filter box 304a. One end of the installation frame 304b is covered with the dustproof cloth 304c. The dustproof cloth 304c is a non-woven fabric used in traditional dust filtration equipment, which can effectively filter the dust in the device.
[0025] The partition assembly 400 includes a mounting bracket 401, which is installed at the top center of the inner wall of the combustion chamber 101. A rotating shaft 402 is rotatably mounted on the bottom of the mounting bracket 401. The rotating shaft 402 can drive a baffle 403 to rotate. The baffle 403 is installed at the bottom of the rotating shaft 402. When the baffle 403 rotates downward, it can become vertical, thereby blocking the combustion chamber 101, reducing the space of the combustion chamber 101, reducing the space required for hot air heating, and thus quickly heating the regenerator 104. The rotating shaft 402 extends to the outside of the combustion chamber 101, and a driven gear 405 is installed at one end. The partition assembly 400 also includes a drive motor 404, which is fixedly installed on the top of the combustion chamber 101. The rotor of the drive motor 404 meshes with the driven gear 405 through a gear. The drive motor 404 can rotate to drive the driven gear 405 to rotate, thereby causing the rotating shaft 402 to change the position of the baffle 403 at the bottom.
[0026] This embodiment has the following workflow: Before cleaning the regenerator 104, the drive motor 404 can be started, which drives the driven gear 405 and the baffle 403 to rotate. When the driven gear 405 rotates to a certain position, the baffle 403 is in a vertical state and will separate the combustion chamber 101. At this time, the high-temperature gas generated by the air intake blower 303 and other components will enter the combustion chamber 101 and the regenerator 104 at the bottom. After use, the drive motor 404 can be restarted to rotate the baffle 403 to a horizontal position. At this time, the bottom of the feed pipe 301a can be sealed to prevent the exhaust gas from entering the hot air structure 302 through the feed pipe 301a and contaminating the internal equipment of the hot air structure 302.
[0027] Furthermore, in order to provide a concise description of exemplary embodiments, not all features of actual embodiments (i.e., those features that are not relevant to the best mode of carrying out the present invention as currently considered, or those features that are not relevant to the implementation of the present invention) may be omitted.
[0028] 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.
[0029] 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.
