Description

Technical Field

[0001] This utility model relates to the field of activated carbon adsorption and desorption technology, specifically to an activated carbon adsorption catalytic combustion device. Background Technology

[0002] Industrial production processes generate large amounts of waste gas containing volatile organic compounds. Direct emission of this waste gas not only pollutes the environment but also harms human health. Therefore, effective treatment of industrial waste gas is crucial.

[0003] Currently, activated carbon catalytic combustion technology has become one of the mainstream methods for treating volatile organic waste gas due to its ability to completely oxidize and decompose organic matter at low temperatures, low energy consumption, and high purification efficiency.

[0004] However, existing activated carbon catalytic combustion equipment still has significant shortcomings in practical applications: most equipment only uses a single-layer or double-layer activated carbon adsorption structure, which is not thorough in filtering and adsorbing complex components of waste gas, making it difficult to meet stringent emission standards; more importantly, as a core component, activated carbon is extremely cumbersome to clean and replace—traditional equipment lacks a dedicated and convenient operating structure, requiring the disassembly of multiple parts during replacement, which is not only time-consuming and labor-intensive, but also affects the equipment's sealing performance due to frequent disassembly and assembly, leading to decreased operational stability and indirectly reducing combustion efficiency, thus failing to meet the modern industrial demand for efficient and easy-to-maintain waste gas treatment equipment.

[0005] For example, application number CN216346314U discloses a high-efficiency catalytic combustion device for activated carbon adsorption-desorption, including a treatment box. An exhaust pipe is fixedly installed at the top of the treatment box, and the treatment box is connected to the exhaust pipe. An exhaust pipe is opened on one side of the treatment box. A combustion box is fixedly installed inside the treatment box, and an intake pipe is installed through the circumferential side wall of the exhaust pipe. The intake pipe is located on the upper section of the circumferential side wall of the exhaust pipe, and a valve is fixedly installed on one side of the intake pipe. However, although this combustion device adds a cleaning structure, internal impurities or foreign objects cannot be quickly and effectively cleaned. Cleaning requires disassembly, but after disassembly, the device cannot operate again, resulting in low equipment efficiency and failing to meet the needs of high-frequency application scenarios.

[0006] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0007] In view of the problems in the related technologies, this utility model proposes an activated carbon adsorption catalytic combustion device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0008] Therefore, the specific technical solution adopted by this utility model is as follows:

[0009] An activated carbon adsorption catalytic combustion device, comprising:

[0010] Box;

[0011] Supporting partitions are installed on both sides inside the chamber, dividing the interior of the chamber into a combustion chamber, an adsorption chamber, and an exhaust chamber;

[0012] The drawer is positioned between two supporting shelves;

[0013] An activated carbon adsorption assembly is located at the top of the drawer and is used for activated carbon filtration and adsorption of exhaust gases after combustion.

[0014] The hatch is located on the side of the support bulkhead near the combustion chamber, and a hatch drive mechanism that cooperates with the hatch is provided on one side of the support bulkhead.

[0015] The air intake pipe is located at the top of the enclosure;

[0016] The air outlet pipe is located on one side of the enclosure.

[0017] Furthermore, in order to integrate the functions of exhaust gas combustion, activated carbon adsorption and tail gas emission filtration inside the housing, exhaust gas is introduced and discharged through the intake pipe and exhaust pipe. The combustion chamber is equipped with a combustion box, and the exhaust chamber is equipped with a filter screen; an air inlet is provided at the top of the intake pipe.

[0018] Furthermore, in order to ensure that the openwork structure on both sides of the drawer does not affect the passage of exhaust gas, and to provide stable support for the drawer through the drawer partitions, the support partition located between the adsorption chamber and the exhaust chamber has an openwork structure; multiple drawer partitions are arranged at equal intervals between the two support partitions, and the drawer partitions are located at the bottom of the drawer; the drawer has a frame structure.

[0019] Furthermore, to facilitate the layered installation and replacement of activated carbon columns through a layered structure, the activated carbon columns are arranged in a staggered manner to break the straight path of airflow, forcing the exhaust gas to form turbulence between the carbon columns and prolonging the gas-solid contact time. The activated carbon adsorption component includes a snap-fit ​​plate set at the bottom of the drawer, with several perforated plates on the top of the snap-fit ​​plate. Several pre-reserved holes are arranged in a rectangular pattern at equal intervals inside the perforated plates. Activated carbon columns are interspersed inside the pre-reserved holes, and the activated carbon columns are arranged in a staggered manner.

[0020] Furthermore, in order to open and close the various drawer channels of the adsorption chamber through the hatches, and to ensure that combustion exhaust gas does not flow through the channels during the process of replacing the activated carbon column by pulling out the drawer, the number of hatches and drawers is the same. The hatches and the support partitions are rotatably connected by the hatch hinges, and the opening and closing direction of the hatches is towards the inside of the combustion chamber.

[0021] Furthermore, in order to convert linear motion into rotational power to drive the hatch shaft, the transmission ratio design ensures high torque output with low power consumption, realizing automatic opening and closing of the hatch. The hatch drive mechanism includes a fixed seat set on the side of the support bulkhead away from the combustion chamber. One end of the fixed seat is provided with a connecting seat and is movably connected. An electric push rod is provided on one side of the connecting seat. The support bulkhead and the top of the hatch are provided with transmission grooves. A fixed gear is provided on the side of the transmission groove near the fixed seat, and a transmission gear is provided on the side of the transmission groove near the hatch. A connecting rod is provided at the output end of the electric push rod. The other end of the connecting rod is fixedly connected to one side of the fixed gear. The transmission gear is coaxial with the hatch shaft and is fixedly connected.

[0022] Furthermore, in order to isolate the transmission slot from the chamber inside the drawer below, prevent high-temperature exhaust gas or sparks from entering the mechanical transmission area, and eliminate the risk of ignition of lubricating grease, a sealing partition is installed between the two support partitions and below the transmission slot.

[0023] The beneficial effects of this utility model are as follows:

[0024] 1. Through multi-channel design, activated carbon inside different adsorption chambers can be flexibly replaced during operation, enabling portable and rapid maintenance and cleaning of activated carbon; drawers in different channels are independently packed, and by controlling the opening and closing of the corresponding doors, the stoppage of any drawer does not affect other drawers, and the perforated plate can be replaced independently, thereby solving the pain points of difficult disassembly, difficult replacement, and poor sealing of activated carbon catalytic combustion equipment, and improving the combustion efficiency of the equipment.

[0025] 2. The modular layered structure design facilitates the installation and replacement of drawers and activated carbon columns layer by layer; the rectangular distribution of pre-drilled holes maximizes the use of drawer space and increases the activated carbon filling density; at the same time, the staggered arrangement of activated carbon columns breaks the straight airflow path, forces the exhaust gas to form turbulence between the carbon columns, prolongs the gas-solid contact time, improves adsorption efficiency, and reduces the risk of airflow short-circuiting, avoiding premature local saturation.

The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0034] According to an embodiment of the present invention, an activated carbon adsorption catalytic combustion device is provided.

[0035] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-4 As shown, the activated carbon adsorption catalytic combustion device according to an embodiment of the present invention includes:

[0036] Box 1;

[0037] Support partition 2 is set on both sides inside the box 1, dividing the inside of the box 1 into combustion chamber, adsorption chamber and exhaust chamber;

[0038] Drawer 3 is positioned between two supporting partitions 2;

[0039] The activated carbon adsorption component 4 is located at the top of the drawer 3 and is used for activated carbon filtration and adsorption of the exhaust gas after combustion.

[0040] The hatch 5 is located on the side of the support bulkhead 2 near the combustion chamber, and a hatch drive mechanism 6 that cooperates with the hatch 5 is provided on one side of the support bulkhead 2.

[0041] Air intake pipe 7 is located at the top of housing 1;

[0042] Air outlet pipe 8 is located on one side of the housing 1.

[0043] With the help of the above technical solutions and through the multi-channel design, activated carbon in different adsorption chambers can be flexibly replaced during operation, realizing portable and quick maintenance and cleaning of activated carbon; drawers 3 in different channels are independently packed, and by controlling the opening and closing of the corresponding doors 5, the stoppage of any drawer 3 will not affect other drawers 3, thereby solving the pain points of difficult disassembly, difficult replacement and poor sealing of activated carbon catalytic combustion equipment, and improving the combustion efficiency of the equipment.

[0044] In one embodiment, the combustion chamber is provided with a combustion box 9 inside and a filter screen 10 inside the exhaust chamber; an air inlet 11 is provided at the top of the air inlet pipe 7, so that the box 1 integrates the functions of exhaust gas combustion, activated carbon adsorption and exhaust gas filtration, and exhaust gas is introduced and discharged through the air inlet pipe 7 and the air outlet pipe 8.

[0045] In one embodiment, the support partition 2 located between the adsorption chamber and the exhaust chamber is a hollow structure; a plurality of drawer partitions 12 are arranged at equal intervals between the two support partitions 2, and the drawer partitions 12 are located at the bottom of the drawer 3; the drawer 3 is a frame structure, so that the hollow structure on both sides of the drawer 3 does not affect the passage of exhaust gas, and the drawer partitions 12 provide stable support for the drawer 3.

[0046] In one embodiment, the activated carbon adsorption component 4 includes a snap-fit ​​plate 401 disposed at the bottom of the drawer 3. The top of the snap-fit ​​plate 401 is provided with several perforated plates 402. Several pre-reserved holes 403 are arranged in a rectangular pattern at equal intervals inside the perforated plates 402. Activated carbon columns 404 are interspersed inside the pre-reserved holes 403. The activated carbon columns 404 are arranged in an intermittent and staggered manner, so that the layered structure facilitates the installation and replacement of the activated carbon columns layer by layer. The staggered arrangement of the activated carbon columns 404 breaks the straight path of the airflow, forces the waste gas to form turbulence between the carbon columns, and prolongs the gas-solid contact time.

[0047] In one embodiment, the number of hatches 5 is the same as the number of drawers 3. The hatches 5 and the support partition 2 are rotatably connected by the hatch hinge 13. The opening and closing direction of the hatches 5 is towards the inside of the combustion chamber. Thus, the hatches 5 can realize the opening and closing of each drawer channel of the adsorption chamber, ensuring that combustion exhaust gas will not flow through the channels when the drawer 3 is pulled out to replace the activated carbon column 404.

[0048] In one embodiment, the hatch drive mechanism 6 includes a fixed seat 601 disposed on the side of the support bulkhead 2 away from the combustion chamber. One end of the fixed seat 601 is provided with a connecting seat 602 and is movably connected. An electric push rod 603 is provided on one side of the connecting seat 602. A transmission groove 604 is provided on the top of the support bulkhead 2 and the hatch 5. A fixed gear 605 is provided inside the transmission groove 604 near the fixed seat 601, and a transmission gear 606 is provided inside the transmission groove 604 near the hatch 5. A connecting rod 607 is provided at the output end of the electric push rod 603. The other end of the connecting rod 607 is fixedly connected to one side of the fixed gear 605. The transmission gear 606 is coaxial with the hatch shaft 13 and is fixedly connected, thereby converting linear motion into rotational power to drive the hatch shaft 13 to rotate. The transmission ratio design ensures high torque output with low power consumption, realizing the automatic opening and closing of the hatch 5.

[0049] In one embodiment, for the aforementioned support partition 2, a sealing partition 14 is provided between the two support partitions 2 and below the transmission groove 604, thereby isolating the transmission groove 604 from the chamber in the drawer 3 below, preventing high-temperature exhaust gas or sparks from entering the mechanical transmission area, and eliminating the risk of ignition of lubricating grease.

[0050] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0051] In practical applications, exhaust gas enters the combustion chamber from the air inlet 11 at the top of the housing 1 through the air inlet pipe 7, where it undergoes catalytic combustion in the combustion chamber 9, decomposing organic matter into harmless CO2 and H2O. After combustion, the gas enters the adsorption chamber and passes through the activated carbon adsorption assembly 4 in the drawer 3. The activated carbon columns 404 are fixed in a staggered manner to the reserved holes 403 of the perforated plate 402, forcing the airflow to form turbulence to prolong the contact time and efficiently adsorb residual pollutants. The purified gas enters the exhaust chamber through the perforated support partition 2, where particulate matter is intercepted by the filter screen 10 and then discharged through the exhaust pipe. When the activated carbon is saturated and needs to be replaced, the door drive mechanism 6 is activated: the electric push rod 603 pushes the linkage rod 607 to drive the fixed gear 605 to rotate, and drives the door shaft 13 through the transmission gear 606 to close the corresponding door 5 into the combustion chamber; at this time, the frame-type drawer 3 can be pulled out to replace the activated carbon column 404; after replacement, the door 5 can be opened to restore the operation of the channel. The unoperated drawers continue to work because the independent doors are kept closed, realizing maintenance without stopping the machine.

[0052] In summary, by utilizing the above-mentioned technical solution of this utility model, the multi-channel design allows for flexible replacement of activated carbon inside different adsorption chambers during operation, enabling portable and rapid maintenance and cleaning of the activated carbon. The drawers 3 in different channels are independently packed, and by controlling the opening and closing of the corresponding doors 5, the cessation of operation of any one drawer 3 does not affect the others. The perforated plate 402 can be replaced independently, thus solving the pain points of difficult disassembly, difficult replacement, and poor sealing of activated carbon catalytic combustion equipment, and improving the combustion efficiency of the equipment. The modular layered structure design facilitates the layer-by-layer installation and replacement of drawers 3 and activated carbon columns 404. The rectangular distribution of the pre-drilled holes 403 maximizes the use of drawer 3 space and increases the activated carbon filling density. Simultaneously, the staggered arrangement of the activated carbon columns 404 breaks the straight airflow path, forcing the exhaust gas to form turbulence between the carbon columns, extending the gas-solid contact time, improving adsorption efficiency, reducing the risk of airflow short-circuiting, and avoiding premature local saturation.
