Description

Technical Field

[0001] This utility model relates to the field of industrial waste gas treatment technology, and more specifically, to an integrated RCO catalytic combustion waste gas treatment device. Background Technology

[0002] In the industrial production sector, such as chemical, coating, printing, and electronics manufacturing industries, industrial waste gases containing harmful substances such as volatile organic compounds (VOCs), benzene, ketones, and esters are continuously generated. If these waste gases are directly emitted without effective treatment, they will not only cause serious pollution to the atmospheric environment, leading to environmental problems such as ozone pollution and PM2.5 precursors, but will also harm human health through inhalation and skin contact, causing health risks such as respiratory diseases and nervous system damage.

[0003] Existing RCO (Regenerative Catalytic Oxidation) devices often employ a split-structure design consisting of a "waste gas pretreatment unit - heat storage unit - catalytic combustion unit - exhaust unit," requiring long-distance pipeline connections between each unit, significantly increasing the overall footprint of the system. For small and medium-sized enterprises with limited factory space, this presents significant challenges in site selection, sometimes necessitating additional site expansion, increasing infrastructure costs and spatial planning pressure. Furthermore, traditional devices often use fixed installation structures for catalyst components (such as welding and bolting). When catalysts experience activity degradation or poisoning due to long-term use and require replacement, the device casing must be disassembled, and surrounding components removed. This cumbersome and time-consuming process results in prolonged downtime, impacting normal production schedules. Additionally, some devices exhibit poor sealing performance in catalyst installation gaps, leading to waste gas leakage and reduced purification efficiency.

[0004] To address the aforementioned issues, an integrated RCO catalytic combustion waste gas treatment device is proposed. Utility Model Content

[0005] To solve the above-mentioned technical problems, an integrated RCO catalytic combustion exhaust gas treatment device is provided.

[0006] To achieve the above objectives, the present invention can be implemented using the following technical solutions: This utility model provides an integrated RCO catalytic combustion exhaust gas treatment device, comprising: a treatment box, a partition frame fixedly installed in the middle of the inner side of the treatment box, heat storage bodies fixedly installed on both sides of the partition frame, catalyst plates symmetrically and slidably installed inside the treatment box, sliding strips installed on both sides of the catalyst plates, the sliding strips being slidably connected to the sliding grooves on the inner wall of the treatment box, flexible graphite gaskets adhered to the surface of the catalyst plates, and multiple evenly distributed magnetic absorbing sheets fixedly installed on the surface of the flexible graphite gaskets.

[0007] Preferably, a support platform is fixedly installed at the bottom of the treatment box, a diversion box is fixedly installed in the middle of the support platform, a reversing valve is installed inside the diversion box, diversion pipes are symmetrically installed on both sides of the diversion box, the side of the diversion pipe away from the diversion box is fixedly connected to the bottom of the treatment box, an exhaust pipe is fixedly installed on one side of the diversion box, and an exhaust pipe is fixedly installed on one side of the treatment box.

[0008] Preferably, a burner is fixedly installed on the top inner side of the treatment box, and a maintenance plate is detachably installed on one outer wall of the treatment box by bolts.

[0009] Preferably, an operation panel is detachably mounted on one side of the support platform via bolts.

[0010] Preferably, the inner wall of the processing box is made of high-temperature resistant material, and the heat storage body is made of ceramic material.

[0011] In summary, the integrated RCO catalytic combustion waste gas treatment device of this utility model has the following features and advantages: This device highly integrates core components such as the treatment box, diversion box, support platform, and control panel. On the one hand, it eliminates long-distance connecting pipes between units and directly divides the "heat storage-catalytic combustion" functional area inside the treatment box, realizing a closed loop within the entire waste gas treatment process. On the other hand, the integrated fixed design of the support platform with the treatment box and diversion box further reduces the overall size of the equipment. Compared with traditional split devices, this device occupies significantly less space and can be installed without additional site expansion. It is especially suitable for small and medium-sized enterprises with limited factory space, significantly reducing enterprise infrastructure costs and space planning pressure, and improving site utilization.

[0012] The catalyst plate of this device is slidably connected to the slide groove by a sliding strip, and is fixed with the help of magnetic plates on the flexible graphite gasket. When replacing, there is no need to disassemble the device shell. The catalyst plate can be directly pulled out by simply opening the inspection plate. The operation process is simplified, the downtime of the equipment is reduced, the exhaust gas leakage caused by disassembly during maintenance is avoided, the impact on the company's production progress and the risk of secondary pollution are reduced, and the convenience and safety of maintenance are significantly improved.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0015] See Figures 1-4 As shown, this is an embodiment of the present invention. The integrated RCO catalytic combustion exhaust gas treatment device provided will be described in detail below: Integrated RCO catalytic combustion exhaust gas treatment device, such as Figures 1-4As shown, the system includes: a treatment chamber 1, a partition frame 10 fixedly installed in the middle of the inner side of the treatment chamber 1, heat storage bodies 9 fixedly installed on both sides of the partition frame 10, catalyst plates 7 symmetrically slidably installed inside the treatment chamber 1, sliding strips 16 installed on both sides of the catalyst plates 7, the sliding strips 16 slidably connected to the sliding grooves on the inner wall of the treatment chamber 1, flexible graphite gaskets 14 adhered to the surface of the catalyst plates 7, and multiple evenly distributed magnetic absorbing sheets 15 fixedly installed on the surface of the flexible graphite gaskets 14. The waste gas distributed by the diversion pipe 13 enters the corresponding side chamber from the bottom of the treatment chamber 1 and fully contacts the heat storage body 9 in the chamber. The heat storage body 9 is made of ceramic material and has excellent heat storage performance. The heat stored in it comes from the heat generated by the previous combustion of the burner 12. When the waste gas flows through the heat storage body 9, it is rapidly preheated to a temperature close to that required for the catalytic reaction, greatly reducing the energy consumption required for subsequent heating and realizing the recycling of energy. The preheated waste gas continues to flow upward and enters the treatment chamber. The catalytic reaction zone inside chamber 1 is in contact with symmetrically installed catalyst plates 7. Under the catalytic action of catalyst plates 7, harmful substances such as volatile organic compounds (VOCs) in the exhaust gas are oxidized and decomposed into harmless CO2 and H2O. If the temperature of the exhaust gas after preheating does not reach the catalytic reaction threshold, the burner 12 on the top of the inner side of the treatment chamber 1 will automatically start and heat to the reaction temperature to ensure complete oxidation. At the same time, the flexible graphite gasket 14 on the surface of catalyst plate 7 can seal the gap between the plate and the inner wall of treatment chamber 1 to prevent leakage of untreated exhaust gas and ensure purification efficiency. When the catalyst plate 7 experiences activity decay due to long-term use, the inspection plate 2 on one side of treatment chamber 1 can be removed. The catalyst plate 7 can be directly pulled out and replaced by sliding the sliding strips 16 on both sides of catalyst plate 7 and the sliding grooves on the inner wall of treatment chamber 1. At the same time, the magnetic suction piece 15 on the surface of the flexible graphite gasket 14 can be used to quickly fix the new plate, reducing equipment downtime and ensuring continuous and efficient operation of the device.

[0016] Furthermore, such as Figures 1-4 As shown, a support platform 3 is fixedly installed at the bottom of the treatment box 1, and a diversion box 5 is fixedly installed in the middle of the support platform 3. A reversing valve 11 is installed inside the diversion box 5, and diversion pipes 13 are symmetrically installed on both sides of the diversion box 5. The side of the diversion pipe 13 away from the diversion box 5 is fixedly connected to the bottom of the treatment box 1. An exhaust pipe 4 is fixedly installed on one side of the diversion box 5, and an exhaust pipe 8 is fixedly installed on one side of the treatment box 1. Industrial waste gas first enters the device through the exhaust pipe 4 and is directly transported to the diversion box 5 in the middle of the support platform 3. At this time, the reversing valve 11 inside the diversion box 5 is activated according to the preset program to evenly distribute the waste gas to the two symmetrical diversion pipes 13. The reversing valve 11 can flexibly switch the airflow direction to ensure that the waste gas can alternately enter the chambers on both sides of the partition frame 10 inside the treatment box 1, laying the foundation for the subsequent alternating cycle of "heat storage-heat release" and avoiding efficiency loss caused by excessive load on a single chamber.

[0017] Furthermore, a burner 12 is fixedly installed on the top inner side of the treatment box 1. A maintenance plate 2 is detachably installed on one side of the outer wall of the treatment box 1 by bolts. An operation panel 6 is detachably installed on one side of the support platform 3 by bolts. The inner wall of the treatment box 1 is made of high-temperature resistant material, and the heat storage body 9 is made of ceramic material. During the operation of the device, the operator can monitor key parameters such as exhaust gas concentration, reaction temperature, and reversing valve 11 status in real time through the operation panel 6 on one side of the support platform 3, and adjust the operating parameters in a timely manner to ensure the treatment effect. The maintenance plate 2 on one side of the treatment box 1 can be removed by bolts to repair the inside of the treatment box 1. The heat storage body 9 is made of ceramic material and has excellent heat storage performance.

[0018] (Catalyst plate 7, reversing valve 11, and burner 12 are existing technologies and will not be described in detail here.) Specifically, industrial waste gas first enters the device through waste gas pipe 4 and is directly transported to the distribution box 5 in the middle of the support platform 3. At this time, the reversing valve 11 inside the distribution box 5 is activated according to the preset program, and the waste gas is evenly distributed to the two symmetrical distribution pipes 13 on both sides. The reversing valve 11 can flexibly switch the airflow direction to ensure that the waste gas can alternately enter the chambers on both sides of the partition frame 10 in the treatment box 1, laying the foundation for the subsequent alternating cycle of "heat storage-heat release" and avoiding efficiency loss caused by excessive load on a single chamber. The waste gas distributed by the distribution pipe 13 enters the corresponding chamber from the bottom of the treatment box 1 and comes into full contact with the heat storage body 9 in the chamber. The heat storage body 9 is made of ceramic material and has excellent heat storage performance. The heat stored in it comes from the heat generated by the previous combustion of the burner 12. When the waste gas flows through the heat storage body 9, it is quickly preheated to a temperature close to that required for the catalytic reaction, which greatly reduces the energy consumption required for subsequent heating and realizes the recycling of energy. The preheated waste gas continues to flow upward and enters the catalytic reaction area in the treatment box 1, where it interacts with the symmetrically installed catalyst plates 7. Upon contact, under the catalytic action of catalyst plate 7, harmful substances such as volatile organic compounds (VOCs) in the waste gas are oxidized and decomposed into harmless CO2 and H2O. If the temperature of the waste gas after preheating does not reach the catalytic reaction threshold, the burner 12 on the top of the inner side of the treatment chamber 1 will automatically start and heat to the reaction temperature to ensure complete oxidation. At the same time, the flexible graphite gasket 14 on the surface of catalyst plate 7 can seal the gap between the plate and the inner wall of the treatment chamber 1 to prevent leakage of untreated waste gas and ensure purification efficiency. The high-temperature purified gas generated by the catalytic combustion reaction will flow downward through the heat storage body 9 on the other side (at this time, the heat storage body 9 on this side is in "heat storage"). In the heat storage chamber 9, the gas transfers heat to the heat storage medium 9, causing its own temperature to drop significantly. The purified gas, having completed heat recovery, is then discharged through the exhaust pipe 8 on one side of the treatment chamber 1, achieving compliant emissions. When one heat storage medium 9 becomes saturated and the other heat storage medium 9 releases heat, the reversing valve 11 in the diversion box 5 switches again, allowing newly introduced exhaust gas to enter the chamber that has completed heat storage, repeating the process of "preheating - catalytic combustion - heat recovery". The process achieves continuous and stable waste gas treatment and energy recovery through the alternating operation of two sets of heat storage bodies 9. During the operation of the device, the operator can monitor key parameters such as waste gas concentration, reaction temperature, and reversing valve 11 status in real time through the operation panel 6 on one side of the support platform 3, and adjust the operating parameters in a timely manner to ensure the treatment effect. When the catalyst plate 7 experiences activity decay due to long-term use, the inspection plate 2 on one side of the treatment box 1 can be removed. The catalyst plate 7 can be directly pulled out and replaced by sliding the sliding strips 16 on both sides of the catalyst plate 7 and the sliding grooves on the inner wall of the treatment box 1. At the same time, the magnetic absorbing sheet 15 on the surface of the flexible graphite gasket 14 is used to quickly fix the new plate, reducing equipment downtime and ensuring continuous and efficient operation of the device.

[0019] The above description is merely an embodiment of this utility model and is not intended to limit this utility model.
