Description

Technical Field

[0001] This application relates to the technical field of waste gas treatment, and in particular to a solid-state battery laboratory waste gas treatment device. Background Technology

[0002] In the field of solid-state battery material preparation, technological advancements have increased the demand for improving the dispersibility and film-forming properties of electrode slurries. Organic solvents or additives such as benzyl alcohol and butyl acetate are commonly used in the preparation process. These solvents or additives are prone to volatilization during experimental steps such as slurry stirring and drying, generating multi-component organic waste gases. These waste gases pollute the experimental environment and threaten the health of personnel; therefore, effective treatment of these waste gases has become a crucial issue that needs to be addressed.

[0003] In traditional solid-state battery laboratory exhaust gas treatment, the following methods are commonly used: First, spray towers are used to absorb soluble components in the exhaust gas through spray liquid, but it is difficult to remove non-water-soluble organic matter; second, activated carbon adsorption is used to adsorb organic matter in the exhaust gas, but the adsorption capacity is limited and frequent replacement is required; third, catalytic combustion is used to decompose organic matter through high-temperature catalytic oxidation, but it is energy-intensive and prone to secondary pollution. Existing exhaust gas treatment methods have obvious defects.

[0004] Therefore, it is necessary to develop a solid-state battery laboratory exhaust gas treatment device to address the inability of existing exhaust gas treatment methods to meet the high efficiency, safety, and environmental protection requirements of solid-state battery laboratory exhaust gas treatment, which has become an important issue that urgently needs to be addressed. Utility Model Content

[0005] To address the shortcomings of existing waste gas treatment methods in meeting the high efficiency, safety, and environmental protection requirements of solid-state battery laboratory waste gas treatment, this application provides a solid-state battery laboratory waste gas treatment device.

[0006] A solid-state battery laboratory exhaust gas treatment device includes a main treatment unit and a re-treatment unit. The main treatment unit includes a first spray tower, a first dry filter, and a catalytic oxidation furnace connected in sequence by pipelines. The re-treatment unit includes a second spray tower, a second dry filter, and a zeolite adsorption fixed bed unit connected in sequence by pipelines. The zeolite adsorption fixed bed unit includes multiple adsorption chambers arranged in parallel. Each adsorption chamber is provided with a zeolite adsorption layer and a deheating device. The catalytic oxidation furnace has a first return pipeline and a first discharge pipeline leading to the atmosphere at its outlet. The first return pipeline is connected to the inlet of the second spray tower. The adsorption box is provided with a first inlet, a first outlet, and a second outlet. The first inlet of the adsorption box is connected to the outlet of the second dry filter through a pipeline. The first outlet of the adsorption box leads to the atmosphere through the second discharge pipeline. The second outlet of the adsorption box is connected to the inlet of the catalytic oxidation furnace through a desorption conveying pipeline.

[0007] By adopting the above technical solution, the solid-state battery laboratory exhaust gas treatment device of this application achieves efficient, safe and environmentally friendly treatment of exhaust gas through the synergistic effect of the main treatment mechanism and the re-treatment mechanism. The first spray tower in the main treatment mechanism can effectively absorb soluble components in the exhaust gas and reduce the concentration of pollutants in the exhaust gas. Subsequently, the first dry filter further filters out particulate matter in the exhaust gas to ensure the quality of exhaust gas entering the catalytic oxidation furnace. The catalytic oxidation furnace decomposes the organic matter in the exhaust gas into harmless carbon dioxide and water through high-temperature catalytic oxidation reaction. The treated exhaust gas is tested. If the test meets the standard, it is discharged. If the test does not meet the standard, it is sent to the re-treatment mechanism. The second spray tower and second dry filter of the reprocessing unit function similarly to their counterparts in the main processing unit. After being treated by the main processing unit, the exhaust gas enters the zeolite adsorption fixed bed unit through the second spray tower and second dry filter. The zeolite adsorption layer in the adsorption box can adsorb the residual organic matter in the exhaust gas and then discharge it into the atmosphere. The desorption heating device desorbs the organic matter on the zeolite adsorption layer by heating and sends it back to the catalytic oxidation furnace for reprocessing through the desorption conveying pipeline. This realizes the recycling of the zeolite adsorption layer and the thorough purification of the exhaust gas, effectively improving the exhaust gas treatment effect and the treatment efficiency of the device, and meeting the high efficiency, safety and environmental protection requirements of solid-state battery laboratory exhaust gas treatment.

[0008] Furthermore, the adsorption box is also provided with a second air inlet, and the outlet of the catalytic oxidation furnace also includes a second reflux pipe, which is connected to the second air inlet of the adsorption box.

[0009] By adopting the above technical solution, the second return pipeline is connected to the second air inlet of the adsorption box, realizing the function of partially returning the gas treated by the catalytic oxidation furnace to the adsorption box for secondary treatment. Specifically, the second return pipeline introduces part of the gas treated by the catalytic oxidation furnace into the second air inlet of the adsorption box, so that the gas passes through the adsorption of the zeolite adsorption layer again, effectively removing any trace organic matter that may remain. This design further enhances the purification effect of the exhaust gas and ensures that the emitted gas meets higher environmental protection standards.

[0010] Furthermore, a cooling device is installed on the first return pipeline, and a mixing box is installed on the second return pipeline. The mixing box is also connected to a cooler.

[0011] By adopting the above technical solutions, the cooling equipment on the first return pipeline can effectively reduce the temperature of the gas returning from the catalytic oxidation furnace to the second spray tower, preventing high-temperature gas from adversely affecting the second spray tower and ensuring its normal operation and spraying effect. Meanwhile, the mixing box on the second return pipeline can fully mix the return gas with the cold air provided by the cooler, further adjusting the return gas to a suitable temperature before it enters the adsorption box, ensuring that the zeolite adsorption layer operates at a suitable temperature, thereby improving adsorption efficiency and service life. This design optimizes the temperature conditions in the waste gas treatment process and improves the stability and treatment efficiency of the entire waste gas treatment device.

[0012] Furthermore, both the first spray tower and the second spray tower are provided with a gas distribution layer, a packing layer, a spray layer and a demisting layer from bottom to top.

[0013] By adopting the above technical solution, the gas distribution layer set in the first and second spray towers can make the waste gas entering the spray towers evenly distributed. The packing layer increases the contact area and contact time between the waste gas and the spray liquid, so that the soluble components in the waste gas can be absorbed more fully. The spray layer cools the waste gas and removes soluble particles or acidic components by spraying the waste gas with the spray liquid. Furthermore, the demister layer can remove water mist from the waste gas, ensuring that the discharged gas is dry. This multi-layer structure design improves the absorption efficiency and treatment effect of the spray tower for soluble components in the waste gas.

[0014] Furthermore, both the first and second dry filters are provided with inspection doors at the bottom, and both the first and second dry filters are provided with removable filter elements inside and dust collection tanks at the bottom.

[0015] By adopting the above technical solutions, the inspection doors at the bottom of the first and second dry filters allow staff to regularly open them for inspection and maintenance, promptly identify and address any potential problems, and ensure the normal operation of the filters. The removable filter elements inside can be easily replaced when they reach the end of their service life or when their filtration efficiency declines, ensuring the filter's performance. The dust collection tank at the bottom collects filtered dust and other particulate matter for easy centralized cleaning. This design improves the maintainability and ease of use of the dry filters and ensures the stable operation of the entire waste gas treatment device.

[0016] Furthermore, the zeolite adsorption layer includes multiple horizontally arranged perforated support plates, with granular zeolite adsorption material filling the spaces between the support plates. The desorption heating device includes an electric heating tube integrated inside the adsorption chamber, which is used to heat and desorb the organic matter adsorbed by the zeolite adsorption layer. The outer wall of the adsorption chamber is covered with an insulation layer, and a temperature sensor and a venting plate are provided on the top of the adsorption chamber.

[0017] By adopting the above technical solution, the zeolite adsorption layer adopts a multi-layer horizontally arranged perforated support plate design. The granular zeolite adsorption material filled between the support plates can effectively adsorb organic matter in the waste gas. The desorption heating device is integrated into the electric heating tube inside the adsorption box, which can uniformly heat the zeolite adsorption layer, so that the adsorbed organic matter is desorbed and the zeolite adsorption material can be recycled. Furthermore, the heat insulation layer covering the outer wall of the adsorption box can reduce heat loss, improve heating efficiency, and reduce energy consumption. The temperature sensor set on the top of the adsorption box can monitor the temperature inside the adsorption box in real time to ensure that the desorption process is carried out within a suitable temperature range, while the explosion relief plate can release pressure in time when the pressure inside the box is too high, ensuring the safe operation of the device. This design improves the adsorption efficiency, service life and safety of the zeolite adsorption fixed bed unit.

[0018] Furthermore, the catalytic oxidation furnace includes a preheating zone and a catalytic reaction zone. A gas distribution plate is provided between the preheating zone and the catalytic reaction zone. The catalytic reaction zone is filled with a honeycomb ceramic carrier on which the catalyst is loaded. The inner wall of the catalytic oxidation furnace is provided with a heat insulation layer. An electric heating sleeve and a thermocouple temperature control system are provided on the outer side of the catalytic oxidation furnace.

[0019] By adopting the above technical solutions, the preheating zone inside the catalytic oxidation furnace can preheat the incoming waste gas, increasing its temperature and making it easier for the gas to react in the subsequent catalytic reaction zone. The gas distribution plate between the preheating zone and the catalytic reaction zone ensures that the preheated waste gas is evenly distributed in the catalytic reaction zone, guaranteeing sufficient contact between the waste gas and the catalyst. Furthermore, the catalytic reaction zone is filled with a honeycomb ceramic carrier with a catalyst loaded on its surface, providing ample active sites for catalytic reaction, allowing the organic matter in the waste gas to undergo catalytic oxidation under the action of the catalyst, decomposing into harmless carbon dioxide and water. At the same time, the insulation layer on the inner wall of the catalytic oxidation furnace reduces heat loss, lowers energy consumption, and improves catalytic oxidation efficiency. The electric heating sleeve on the outside heats the catalytic oxidation furnace, and the thermocouple temperature control system monitors and controls the temperature inside the catalytic oxidation furnace in real time, ensuring that the catalytic oxidation reaction takes place under suitable temperature conditions. This design enables the catalytic oxidation furnace to efficiently and stably catalytically oxidize the organic matter in the waste gas.

[0020] Furthermore, a non-methane total hydrocarbon detector is installed at the outlet end of the catalytic oxidation furnace, and hydrogen sulfide detectors are installed at the outlet ends of the first and second emission pipelines.

[0021] By adopting the above technical solution, the non-methane total hydrocarbon detector installed at the outlet of the catalytic oxidation furnace can detect the content of non-methane total hydrocarbons in the waste gas after treatment by the catalytic oxidation furnace in real time, thereby determining whether the treatment effect of the catalytic oxidation furnace on organic matter meets the standards. If the non-methane total hydrocarbon content is detected to exceed the standard, it indicates that the waste gas treatment has not reached the ideal state. At this time, the waste gas can be guided to the reprocessing unit for further treatment. The hydrogen sulfide detector installed at the outlet of the first and second emission pipelines can detect the content of hydrogen sulfide in the emission gas. Once the hydrogen sulfide content is detected to exceed the standard, the system will immediately issue an alarm and take corresponding treatment measures to ensure that the emission gas meets environmental protection standards, protect the environment and human health, effectively realize real-time monitoring and precise control of the waste gas treatment effect, and effectively improve the reliability and environmental protection of the waste gas treatment device.

[0022] Furthermore, controlled valves are provided at the first discharge pipeline, the first return pipeline, the second return pipeline, the desorption conveying pipeline, and the first air inlet, the second air inlet, the first air outlet, and the second air outlet of the adsorption box.

[0023] By adopting the above technical solution, the control valve design can precisely control the flow direction of the exhaust gas. During the exhaust gas treatment process, these control valves can be adjusted according to the detection results or actual needs to flexibly switch the exhaust gas emission or return path. This design improves the exhaust gas treatment efficiency and the stability of the device operation. For example, when the exhaust gas after treatment by the catalytic oxidation furnace meets the detection standards, the control valve of the first emission pipeline is opened to allow the exhaust gas to be directly discharged into the atmosphere. If the detection does not meet the standards, the control valve of the first emission pipeline is closed, and the control valve of the first return pipeline is opened to return the exhaust gas to the reprocessing unit for further treatment.

[0024] Furthermore, the waste gas treatment device also includes a control box, which contains a PLC main control unit for controlling the operation of the main treatment mechanism and the re-treatment mechanism.

[0025] By adopting the above technical solution, the main processing mechanism and the reprocessing mechanism are controlled by the PLC main control unit in the control box, reducing manual intervention, realizing automated operation, and improving the operating efficiency and stability of the waste gas treatment device.

[0026] In summary, this application includes at least the following beneficial technical effects: 1. The main treatment unit and the re-treatment unit work together to comprehensively treat low-concentration and high-concentration waste gas generated in the solid-state battery laboratory. Moreover, the multiple parallel adsorption chambers of the zeolite adsorption fixed bed unit can alternately perform adsorption and desorption, realizing the recycling of the zeolite adsorption layer and the thorough purification of waste gas, effectively improving the waste gas treatment effect and the treatment efficiency of the device. 2. The PLC main control unit in the control box can control the operation of the entire waste gas treatment device, realize the circulation treatment and safety protection, and meet the needs of the solid-state battery laboratory for efficient, safe and environmentally friendly waste gas treatment.

[0029] The following combination Figure 1 The technical solutions in the embodiments of this utility model will be described in detail.

[0030] See Figure 1 This invention provides a solid-state battery laboratory exhaust gas treatment device, including a main treatment unit 1 and a re-treatment unit 2. The main treatment unit 1 includes a first spray tower 11, a first dry filter 12 and a catalytic oxidation furnace 13 connected in sequence by pipelines. The re-treatment unit 2 includes a second spray tower 21, a second dry filter 22 and a zeolite adsorption fixed bed unit 23 connected in sequence by pipelines. The zeolite adsorption fixed bed unit 23 includes a plurality of adsorption boxes 231 arranged in parallel. In this embodiment, two adsorption boxes 231 are arranged in parallel. The adsorption box 231 is provided with a zeolite adsorption layer and a deheating device. The adsorption box 231 is provided with a first air inlet 2311, a second air inlet 2312, a first air outlet 2313, and a second air outlet 2314. The air outlet of the catalytic oxidation furnace 13 is divided into a first return pipe 131, a second return pipe 132, and a first discharge pipe 133 leading to the atmosphere. The first return pipe 131 is connected to the air inlet of the second spray tower 21. The first air inlet 2311 of the adsorption box 231 is connected to the air outlet of the second dry filter 22 through a pipe. The first air outlet 2313 of the adsorption box 231 leads to the atmosphere through the second discharge pipe 24. The second air outlet 2314 of the adsorption box 231 is connected to the air inlet of the catalytic oxidation furnace 13 through a desorption conveying pipe 25. The second return pipe 132 is connected to the second air inlet 2312 of the adsorption box 231.

[0031] To achieve real-time monitoring and precise control of the waste gas treatment effect, a non-methane total hydrocarbon detector 14 is installed at the outlet end of the catalytic oxidation furnace 13 to detect and determine whether the treatment effect of the catalytic oxidation furnace on organic matter meets the standards. A hydrogen sulfide detector is installed at the outlet end of the first discharge pipeline 133 and the second discharge pipeline 24 to detect whether the hydrogen sulfide content in the emission gas exceeds the standard. When the hydrogen sulfide content exceeds the standard, an alarm will sound and the emission will be suspended.

[0032] To enable flexible switching of exhaust gas emission or recirculation paths, controlled valves 15 are installed at the first recirculation pipeline 131, the second recirculation pipeline 132, the first emission pipeline 133, the second emission pipeline 24, the desorption conveying pipeline 25, and the first air inlet 2311, the second air inlet 2312, the first air outlet 2313, and the second air outlet 2314 of the adsorption box 231, thereby precisely controlling the flow direction of exhaust gas.

[0033] To ensure that the exhaust gas is kept at a suitable temperature during the treatment process, a cooling device 1311 is installed on the first return pipe 131, and a mixing box 1321 is installed on the second return pipe 132. The mixing box 1321 is also connected to a cooler 1322.

[0034] Specifically, both the first spray tower 11 and the second spray tower 21 are provided with a gas distribution layer, a packing layer, a spray layer and a demisting layer from bottom to top. After the exhaust gas enters the first spray tower 11 or the second spray tower 21, it passes through the gas distribution layer, the packing layer, the spray layer and the demisting layer in sequence and is discharged from the top outlet end of the first spray tower 11 or the second spray tower 21 and enters the first dry filter 12 or the second dry filter 22.

[0036] Furthermore, the first dry filter 12 and the second dry filter 22 are rectangular metal box structures. Both the first dry filter 12 and the second dry filter 22 are provided with maintenance doors at the bottom. Both the first dry filter 12 and the second dry filter 22 are provided with detachable filter elements inside and dust collection tanks at the bottom. Their outlet ends are located at the first dry filter 12 or the second dry filter 22 and are connected to the adsorption box 231 of the zeolite adsorption fixed bed unit 23.

[0037] Furthermore, the adsorption box 231 is a rectangular or cylindrical metal shell. The zeolite adsorption layer of the adsorption box 231 includes multiple horizontally arranged perforated support plates, and granular zeolite adsorption material is filled between the support plates to adsorb residual organic matter in the waste gas. The desorption heating device includes an electric heating tube integrated inside the adsorption box 231. The electric heating tube is used to heat and desorb the organic matter adsorbed by the zeolite adsorption layer. The outer wall of the adsorption box 231 is covered with a heat insulation layer, and a temperature sensor and a venting plate are provided on the top of the adsorption box 231.

[0038] Furthermore, the catalytic oxidation furnace 13 includes a preheating zone and a catalytic reaction zone. A gas distribution plate is provided between the preheating zone and the catalytic reaction zone. The catalytic reaction zone is filled with a honeycomb ceramic carrier on which the catalyst is loaded. The inner wall of the catalytic oxidation furnace 13 is provided with a heat insulation layer. An electric heating sleeve and a thermocouple temperature control system are provided on the outer side of the catalytic oxidation furnace 13.

[0039] The catalytic oxidation furnace 13 has a heating temperature range of 250 to 350°C, which catalytically oxidizes and decomposes the waste gas in the catalytic oxidation furnace into CO2 and H2O.

[0040] Alternatively, the catalyst may be a noble metal or transition metal catalyst.

[0041] To achieve automated operation of the waste gas treatment device, the device also includes a control box. The control box contains a PLC main control unit for controlling the operation of the main treatment mechanism 1 and the re-treatment mechanism 2. The PLC main control unit can realize automated operation of the first spray tower 11, the first dry filter 12, the catalytic oxidation furnace 13, the second spray tower 21, the second dry filter 22, the zeolite adsorption fixed bed unit 23, as well as the control valves 15, fans, detectors, etc. in each pipeline.

[0042] See Figure 1 The implementation principle of this application embodiment is as follows: the waste gas treatment device processes waste gases of different concentrations through the coordinated action of the main treatment mechanism 1 and the re-treatment mechanism 2. 1. High-concentration waste gas is pretreated sequentially by the first spray tower 11 and the first dry filter 12 before entering the catalytic oxidation furnace 13 for decomposition. If the test results meet the standards, it is directly discharged through the first discharge pipeline 133. If it does not meet the standards, it is cooled through the first return pipeline 131 and introduced into the reprocessing unit 2. It then sequentially passes through the second spray tower 21 and the second dry filter 22, and enters the zeolite adsorption fixed bed unit 23 for adsorption purification before being discharged through the second discharge pipeline 24. The zeolite adsorption fixed bed unit 23 is equipped with multiple adsorption chambers 231 that can be operated alternately. By switching the control valve, the waste gas is purified in adsorption mode, and in desorption mode, the adsorbed organic matter is desorbed into concentrated gas by electric heating and sent back to the catalytic oxidation furnace 13 for decomposition through the desorption conveying pipeline 25. At the same time, part of the gas from the outlet of the catalytic oxidation furnace 13 is led back to the adsorption chamber 231 through the second return pipeline 132, forming a circulation loop to realize the recycling and regeneration of the adsorbent and improve the treatment effect of the waste gas.

[0043] 2. Low-concentration waste gas is directly introduced into the reprocessing unit 2, passing sequentially through the second spray tower 21 and the second dry filter 22, and then entering the zeolite adsorption fixed bed unit 23 for adsorption and purification. After that, it is discharged through the second discharge pipe 24. Subsequently, in the desorption mode, the adsorbed organic matter is desorbed into concentrated gas by electric heating, and then sent back to the catalytic oxidation furnace 13 for decomposition through the desorption conveying pipe 25. After decomposition, if the waste gas meets the standards, it is directly discharged through the first discharge pipe 133. If it does not meet the standards, part of the effluent is led back to the adsorption box 231 through the second return pipe 132 to form a circulation loop, realize the recycling and regeneration of the adsorbent, and improve the treatment effect of waste gas.
