Description

Technical Field

[0001] This utility model relates to the field of industrial waste gas treatment technology, and in particular to a device for treating tail gas from cyclohexanone production. Background Technology

[0002] Cyclohexanone production is a chemical production process that uses cyclohexane or phenol as the core raw material to prepare cyclohexanone through catalytic oxidation or hydrogenation. Cyclohexanone is a key intermediate in the synthesis of nylon 6 and nylon 66, and is also widely used in solvents, coatings, rubber additives, and other fields. The mainstream industrial process is the cyclohexane oxidation method: cyclohexane and air are first partially oxidized in a reactor under the action of cobalt salt or boric acid catalyst (temperature 150-180℃, pressure 0.8-1.2MPa) to generate cyclohexyl hydrogen peroxide, which is then decomposed to obtain a mixture of cyclohexanone and cyclohexanol (i.e., KA oil). Finally, high-purity cyclohexanone is obtained through distillation separation and purification. Some processes use phenol as raw material, which is first catalytically hydrogenated to obtain cyclohexanol, and then dehydrogenated to generate cyclohexanone. The production process requires supporting equipment such as distillation columns, reactors, and separators, as well as tail gas treatment and wastewater purification systems to ensure environmental compliance.

[0003] However, the existing equipment has the following shortcomings: When using the existing equipment, the filter is generally installed inside the cabinet with bolts. When replacing it, tools are required, which is too cumbersome and causes low replacement efficiency for users.

[0004] Therefore, we propose a tail gas treatment device for cyclohexanone production to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where filters are typically installed with bolts, requiring tools for replacement, which is cumbersome and inefficient. Therefore, this invention proposes a cyclohexanone production tail gas treatment device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cyclohexanone production tail gas treatment device, comprising a cabinet, a cabinet cover, a feed end, a discharge end, a filter, a heat dissipation frame, and a replacement device. The cabinet cover is rotatably connected to the surface of the cabinet. The feed end is fixedly connected to the side of the cabinet. The discharge end is fixedly connected to the top of the cabinet. The filter is installed inside the cabinet. The heat dissipation frame is installed inside the cabinet. The replacement device is installed inside the cabinet. The replacement device includes an installation head and an installation plate. The installation plate is fixedly connected to the inside of the cabinet. The installation head is installed on the top of the filter. A sliding arm is fixedly connected to the side of the installation head. A sliding groove is formed on the side of the installation plate away from the cabinet. The sliding arm is slidably connected inside the sliding groove. A telescopic tube is fixedly connected to the top of the installation head. The top of the telescopic tube is fixedly connected to one end of the discharge end. A positioning hole is formed on the surface of the installation plate. A sliding rod is fixedly connected inside the sliding arm. A moving plate is slidably connected to the surface of the sliding rod.

[0007] Furthermore, a positioning rod is fixedly connected to one end of the movable plate near the mounting plate. The positioning rod is inserted into the positioning hole. By setting the positioning rod, the movable plate can be limited, reducing the difficulty of limiting the movable plate during use.

[0008] Furthermore, a first spring is sleeved and connected to the surface of the slide rod.

[0009] Furthermore, one end of the first spring is fixedly connected to the surface of the movable plate, and the end of the first spring away from the movable plate is fixedly connected to the inside of the sliding arm. The first spring is provided to facilitate the application of a restoring force to the movable plate.

[0010] Furthermore, a heat dissipation assembly is fixedly installed inside the cabinet. The heat dissipation assembly includes a mounting frame and a fan. The fan is fixedly connected inside the mounting frame. A connecting groove is provided inside the cabinet, and the mounting frame is snapped into the connecting groove. A connecting plate is fixedly connected to the side of the mounting frame. A pull hole is provided inside the cabinet, and an insert plate is slidably connected inside the pull hole. The insert plate is inserted into the connecting plate. By setting up the mounting frame and the fan, the hot air inside the cabinet can be blown upwards, reducing the risk of high exhaust gas temperature during equipment operation, which could easily raise the internal temperature of the filter and make it difficult for the filter to filter effectively.

[0011] Furthermore, a second spring is fixedly connected to the end of the insert plate away from the connecting plate, and the end of the second spring away from the insert plate is fixedly connected to the inside of the pull hole. The second spring is provided to facilitate the application of a reset spring force to the insert plate.

[0012] Furthermore, a pull block is fixedly connected to one end surface of the insert plate near the second spring. The pull block is slidably connected inside the pull hole, and the pull block is provided to facilitate the movement of the insert plate.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by setting a replacement device, the filter can be replaced quickly and effectively, thus reducing the need for tools to replace filters, which is usually done by bolting the filter inside the cabinet. This makes the replacement process inefficient.

[0014] 2. In this utility model, by setting up a heat dissipation component, the cabinet is effectively cooled, which plays a role in heat dissipation inside the equipment. This reduces the problem that the exhaust gas temperature inside the cabinet is high when the existing equipment is in use, which can easily raise the temperature inside the cabinet and affect the filter's ability to filter the exhaust gas. This heat dissipation component realizes the convection of the internal temperature of the cabinet and improves the cooling effect of the equipment. Attached Figure Description

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] Please see Figures 1-6 This utility model provides a technical solution: a cyclohexanone production tail gas treatment device, including a cabinet 1, a cabinet cover 2, a feed end 3, a discharge end 4, a filter 5, a heat dissipation frame 6, and a replacement device 7. The cabinet cover 2 is rotatably connected to the surface of the cabinet 1, the feed end 3 is fixedly connected to the side of the cabinet 1, the discharge end 4 is fixedly connected to the upper end of the cabinet 1, the filter 5 is installed inside the cabinet 1, and the heat dissipation frame 6 is installed inside the cabinet 1.

[0020] Cabinet 1 is the core container for exhaust gas treatment, made of high-temperature and corrosion-resistant stainless steel, capable of withstanding the corrosive and high-temperature environment of cyclohexanone production exhaust gas, ensuring structural stability; Cabinet cover 2 is connected to cabinet 1 by hinges, facilitating opening and maintenance of internal components; Feed end 3 is the exhaust gas inlet channel, sealed to the exhaust gas discharge pipe of the production equipment to prevent exhaust gas leakage; Discharge end 4 is the exhaust channel for purified gas, ensuring the safe discharge of compliant gas; Filter 5 is the core component for exhaust gas purification, filled with high-efficiency adsorption material, which can accurately adsorb toxic and harmful substances in the exhaust gas; Heat dissipation frame 6 is the air inlet and outlet device for heat dissipation component 8, assisting in heat exchange inside cabinet 1; Replacement device 7 allows for quick disassembly and assembly of filter 5 without tools, improving maintenance convenience.

[0021] The following section will describe the specific setup and function of the replacement device 7 and the heat dissipation component 8.

[0022] In this implementation scheme: the replacement device 7 is installed inside the cabinet 1. The replacement device 7 includes a mounting head 71 and a mounting plate 72. The mounting plate 72 is the fixed base of the replacement device 7, fixed to the inside of the cabinet 1, and provides sliding support for the sliding arm 74. The mounting head 71 is the connecting component between the filter 5 and the discharge end 4, which can realize the quick docking of the filter 5 and the telescopic pipe 710 to ensure smooth airflow. The mounting plate 72 is fixedly connected to the inside of the cabinet 1. The mounting head 71 is installed on the upper end of the filter 5, and a sliding arm 74 is fixedly connected to the side of the mounting head 71. The mounting plate 72 has a sliding groove 79 on the side away from the cabinet 1. The sliding arm 74 is slidably connected inside the sliding groove 79. The upper end of the mounting head 71 is fixedly connected to a telescopic tube 710. The telescopic tube 710 is made of corrosion-resistant elastic material and can move and extend with the mounting head 71 to ensure that the airflow channel is always sealed. The upper end of the telescopic tube 710 is fixedly connected to one end of the discharge end 4. The surface of the mounting plate 72 has a positioning hole 73. The sliding arm 74 is fixedly connected to a sliding rod 77. The surface of the sliding rod 77 is slidably connected to a moving plate 76.

[0023] Specifically, a positioning rod 75 is fixedly connected to one end of the movable plate 76 near the mounting plate 72, and the positioning rod 75 is inserted into the positioning hole 73.

[0024] In this embodiment, by setting the positioning rod 75, the moving plate 76 can be limited, reducing the difficulty of limiting the moving plate 76 during use.

[0025] Specifically, a first spring 78 is sleeved and connected to the surface of the slide rod 77. The first spring 78 is a compression spring made of high-elasticity spring steel, which has long-lasting elasticity and can provide stable return force.

[0026] Specifically, one end of the first spring 78 is fixedly connected to the surface of the movable plate 76, and the other end of the first spring 78 away from the movable plate 76 is fixedly connected to the inside of the slide arm 74. The first spring 78 is provided to facilitate the application of a restoring force to the movable plate 76.

[0027] In this embodiment: a heat dissipation component 8 is fixedly installed inside the cabinet 1. The heat dissipation component 8 includes a mounting frame 81 and a fan 82. The fan 82 is fixedly connected inside the mounting frame 81. A connecting groove 83 is opened inside the cabinet 1. The mounting frame 81 is snapped into the connecting groove 83. A connecting plate 84 is fixedly connected to the side of the mounting frame 81. A pull hole 85 is opened inside the cabinet 1. An insert plate 86 is slidably connected inside the pull hole 85. The insert plate 86 is inserted into the inside of the connecting plate 84.

[0028] In this embodiment: by setting the mounting frame 81 and the fan 82, the hot air inside the cabinet 1 can be blown upwards, which reduces the situation where the exhaust gas temperature is high during equipment operation, which can easily raise the internal temperature of the filter 5 and make it difficult for the filter 5 to filter effectively.

[0029] Specifically, a second spring 88 is fixedly connected to the end of the insert plate 86 away from the connecting plate 84. The end of the second spring 88 away from the insert plate 86 is fixedly connected to the inside of the pull hole 85. The second spring 88 is provided to facilitate the application of a reset spring force to the insert plate 86.

[0030] Specifically, a pull block 87 is fixedly connected to one end of the insert plate 86 near the second spring 88. The pull block 87 is slidably connected inside the pull hole 85. The pull block 87 is provided to facilitate the movement of the insert plate 86.

[0031] Working Principle: When using the equipment, the user connects the exhaust gas to the feed end 3, and the exhaust gas then enters the filter 5 through the feed end 3. After absorbing and filtering the toxic substances in the exhaust gas, it is discharged through the discharge end 4. When replacing the filter 5, the user pulls the moving plate 76 to move it on the surface of the slide rod 77. When the moving plate 76 moves, it abuts against the first spring 78 to compress and generate elastic force. Then, the moving plate 76 drives the positioning rod 75 to move out of the positioning hole 73. Subsequently, the moving mounting head 71 moves out of the upper end of the filter 5, and the filter 5 is freed from restraint and can be quickly replaced. By setting the replacement device 7, the filter 5 can be quickly replaced, which reduces the need for tools to replace the filter 5, which is usually bolted to the inside of the cabinet 1. The tools are too cumbersome and result in low user replacement efficiency. This replacement device 7 realizes the quick replacement of the filter 5 and improves the user's replacement efficiency.

[0032] By setting up the heat dissipation component 8, before the equipment is used, the mounting frame 81 needs to be installed in the cabinet 1. During installation, the user pulls the pull block 87 to move the insert plate 86, which compresses the second spring 88 to generate elastic force. Then, the connecting plate 84 and the mounting frame 81 are installed in the connecting groove 83. After releasing the restraint of the insert plate 86, the second spring 88 returns to its original position and abuts against the internal insertion connection of the insert plate 86 and the connecting plate 84, limiting the mounting frame 81. By setting up the heat dissipation component 8, the cabinet 1 is effectively cooled, which plays a role in heat dissipation inside the equipment. This reduces the problem that the exhaust gas temperature in the cabinet 1 is high when the existing equipment is in use, which can easily lead to an increase in the temperature inside the cabinet 1. Excessive temperature can easily affect the filtration of exhaust gas by the filter 5. This heat dissipation component 8 realizes the convection of the internal temperature of the cabinet 1 and improves the cooling effect of the equipment.

[0033] The above description discloses only one or more preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above embodiments and making equivalent changes in accordance with the claims of the present utility model still fall within the scope of the present utility model.
