[0001] The present invention relates to the technical field of organic waste gas treatment, and particularly relates to an organic waste gas treatment device and method. Background Technique

[0002] With the continuous development of industrial production, the problem of organic waste gas emission has become increasingly serious, posing a serious threat to the environment and human health. At present, there are various methods for treating organic waste gas, including activated carbon adsorption, catalytic combustion, scrubber absorption and other technologies. The choice of these methods depends on the specific waste gas composition, concentration and emission standards. Among them, catalytic combustion is to heat or burn the organic waste gas to oxidize the harmful substances contained therein to meet the emission standards.

[0003] When the existing organic waste gas treatment device using the catalytic combustion treatment method treats organic waste gas, although it can efficiently purify the organic waste gas, when the treated gas is discharged, part of the heat in the device will be discharged together with the gas, resulting in heat energy loss, increasing the energy consumption of the device, and being unfavorable for the efficient and energy-saving treatment of organic waste gas by the device; for this reason, we propose an organic waste gas treatment device and method.

[0019] Multiple second heat-conducting baffles are fixedly connected to the inner wall of the exhaust pipe from top to bottom at intervals. Two adjacent second heat-conducting baffles are staggered front and back to divide the inner cavity of the exhaust pipe into a labyrinthine air outlet channel.

[0020] Preferably, the explosion-proof pressure relief mechanism includes:

[0021] An explosion-proof leakage pipe is fixedly connected to the top of the furnace body;

[0022] A pressure assembly is installed inside an explosion-proof leak pipe. When the pressure inside the explosion-proof leak pipe reaches a preset threshold, the pressure assembly is used to release and reduce the pressure.

[0023] Preferably, the pressure assembly includes:

[0024] A sealing plate, which is fixedly connected to the bottom of the inner cavity of the explosion-proof leakage pipe;

[0025] A pressure relief pipe is fixedly connected to the top center of the sealing plate and communicates with the bottom of the sealing plate. A leakage port is provided at the bottom of the outer peripheral wall of the pressure relief pipe.

[0026] A piston plate is slidably inserted into a pressure relief tube. The piston plate is equipped with a pressure element that applies downward pressure to the piston plate.

[0027] Preferably, the pressure element includes:

[0028] A column, which is fixedly connected to the middle of the top of the piston plate;

[0029] At least one weight-adding disc is stacked on top of the piston plate and movably connected to the outer wall of the column.

[0030] Preferably, the top of the column is provided with a downwardly extending telescopic cavity, the bottom of the telescopic cavity is fixedly connected with a conductive insert, the top of the telescopic cavity is movably inserted with a guide rod, the bottom end of the guide rod is fixedly embedded with a plug-in switch, the outer wall of the explosion-proof leakage pipe is fixedly installed with a buzzer alarm, and the plug-in switch is electrically connected to the buzzer alarm, so that after the conductive insert and the plug-in switch are inserted, a power supply path for powering the buzzer alarm is formed;

[0031] A connecting rod is fixedly connected to the top of the guide rod, and a crossbeam is fixedly connected to the top of the inner wall of the explosion-proof leakage pipe. The outer wall of the connecting rod is movably inserted into the middle of the crossbeam, and an elastic compression spring is provided between the crossbeam and the guide rod, which is movably sleeved on the outer wall of the connecting rod.

[0032] Preferably, the furnace body has an insulation layer inside, and an inspection port is provided at the top of the outer wall of the furnace body corresponding to the catalytic combustion mechanism.

[0033] On the other hand, the present invention also provides a method for treating organic waste gas, using an organic waste gas treatment device as described in any one of the above claims, comprising the following steps:

[0034] Step 1: Organic waste gas is pumped into the furnace body through the inlet. Heating by electric heating rods and the active micro-points on the catalyst surface of the catalyst support lower the activation energy of the oxidation reaction of harmful substances in the organic waste gas, allowing it to undergo combustion in a low-temperature environment and be converted into harmless carbon dioxide and water vapor. The reacted gas enters the exhaust pipe and is discharged towards the exhaust port. During this process, as the organic waste gas enters the furnace body and is transported upwards, multiple first heat-conducting baffles form a multi-bend labyrinthine air intake channel within the furnace body, extending the air intake path and ensuring full contact between the organic waste gas and the first heat-conducting baffles and the exhaust pipe. Simultaneously, as the treated gas flows downwards in the exhaust pipe, multiple second heat-conducting baffles form a multi-bend labyrinthine air outlet channel within the exhaust pipe, allowing the heat in the treated exhaust gas to be transferred to the heat storage and heat exchange mechanism composed of the exhaust pipe, the first heat-conducting baffles, and the second heat-conducting baffles. This preheats the incoming organic waste gas, reduces the energy consumption of the electric heating rods, and utilizes the heat energy of the exhaust gas.

[0035] Step Two: During the exhaust gas treatment process inside the furnace, if the pressure inside the furnace reaches the preset explosion-proof pressure threshold, the gas pressure will push the piston plate with the weight-increasing plate upward along the inner cavity of the pressure relief pipe, so that the leak port is partially connected to the bottom of the sealing plate, allowing some gas to be discharged from the explosion-proof leak pipe to the outside of the furnace. The upward movement distance of the piston plate is automatically adjusted according to the pressure inside the furnace to control the opening and closing range of the leak port. If the pressure is too high and the piston plate moves up to the position above the leak port, the conductive plug and the plug-in switch at the bottom of the guide rod form a plug-in conductive state, energizing the buzzer alarm to generate an alarm for warning. As the sealing plate continues to move upward, the column pushes the guide rod and drives the guide rod upward. The elasticity of the spring forms a buffer distance to ensure the continuous alarm of the buzzer and reserve reaction time.

[0036] The technical effects and advantages of this invention are as follows:

[0037] This invention, by setting a heat storage and heat exchange mechanism inside the furnace, enables heat exchange between the organic waste gas and the treated tail gas when the organic waste gas enters, so that the heat in the treated tail gas can be used for preheating of the organic waste gas, reducing the heat required for catalytic combustion of the organic waste gas, which helps to reduce energy consumption while improving the utilization rate of thermal energy, thereby achieving the effect of energy saving and emission reduction.

[0038] This invention, by installing an explosion-proof leakage pipe at the top of the furnace body and a pressure component inside the explosion-proof leakage pipe, can adjust the pressure during explosion-proof venting and can also trigger an alarm when the pressure exceeds a preset value. It not only achieves automatic pressure relief and explosion prevention, but also provides automatic alarm to prompt manual intervention to enhance safety protection and make the equipment operation safer and more reliable.

Detailed Implementation

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] This invention provides, for example Figures 1-8 The image shows an organic waste gas treatment device.

[0050] Example 1: Includes a furnace body 100, a catalytic combustion mechanism, a heat storage and heat exchange mechanism, and an explosion-proof pressure relief mechanism. The catalytic combustion mechanism is located at the top of the inner cavity of the furnace body 100 to perform low-temperature catalytic combustion of organic waste gas. The heat storage and heat exchange mechanism is located below the catalytic combustion mechanism to recover and utilize the heat energy in the exhaust gas. The explosion-proof pressure relief mechanism is fixedly connected to the top of the furnace body 100. The organic waste gas reacts in the catalytic combustion mechanism within the furnace body 100, utilizing catalysis to enable combustion at low temperatures, reducing heat energy consumption. When the exhaust gas, after reaction treatment, is discharged through the heat storage and heat exchange mechanism, it can react with the organic waste gas entering the furnace body 100. Heat exchange occurs between the furnace and the catalytic combustion chamber, accumulating and transferring the heat contained in the treated exhaust gas. This preheats the organic waste gas entering the furnace 100, increasing its temperature before it enters the catalytic combustion mechanism. This reduces the heat energy consumption in the catalytic combustion mechanism, achieving not only heat energy recovery and utilization but also reducing energy consumption, thus achieving energy conservation and emission reduction, and realizing economic and environmental value. In addition, the explosion-proof pressure relief mechanism provides safety protection for the reaction environment inside the furnace 100. If the pressure inside the furnace 100 exceeds a preset threshold during the organic waste gas reaction, timely pressure relief operations can be performed to avoid the safety hazard of explosion due to excessive pressure.

[0051] The catalytic combustion mechanism includes a catalyst support 103 and electric heating rods 104. The catalyst support 103 is fixedly connected to the top of the inner cavity of the furnace body 100, and the electric heating rods 104 are fixedly inserted into the top of the inner cavity of the furnace body 100. Multiple electric heating rods 104 are arranged in a U-shape around the catalyst support 103. An insulation layer 105 is provided inside the furnace body 100, and an inspection port 107 is provided at the top of the outer wall of the furnace body 100 corresponding to the position of the catalytic combustion mechanism. In this embodiment, the catalyst support 103 can use a noble metal catalyst (such as platinum (Pt), palladium (Pd), etc.) with high activity, high selectivity, and good thermal stability. This catalyst can utilize its surface active sites to reduce the activation energy of the oxidation reaction of harmful substances (such as volatile organic compounds VOCs) in organic waste gas, allowing the organic waste gas to be oxidized at a relatively low temperature. The combustion reaction occurs, which, compared to traditional high-temperature combustion reactions, not only helps reduce energy consumption but also reduces the generation of secondary pollutants such as nitrogen oxides (NOx). This makes the combustion reaction of organic waste gas in the catalytic combustion mechanism within the furnace body 100 more energy-efficient and environmentally friendly, improving the treatment quality of the organic waste gas. The electric heating rod 104 compensates for the low temperature of the organic waste gas during the initial operation phase, which cannot directly initiate the catalytic combustion reaction. Through the electric heating effect of the electric heating rod 104, electrical energy is converted into heat energy to raise the temperature of the reaction zone to the ignition temperature required by the catalyst, providing the necessary initial conditions for the smooth progress of the catalytic reaction. When the catalytic combustion reaction is stable, the power of the electric heating rod 104 can be adjusted to reduce energy consumption while maintaining the temperature environment required for the reaction.

[0052] The heat storage and heat exchange mechanism includes an exhaust pipe 109, an exhaust port 108, and an air inlet 101. The top end of the exhaust pipe 109 is fixedly connected to the bottom end of the catalyst support 103, and the bottom of the exhaust pipe 109 extends to the bottom of the inner cavity of the furnace body 100. The exhaust port 108 is fixedly located at the bottom of the back of the furnace body 100 and is fixedly connected to the bottom of the exhaust pipe 109. The air inlet 101 is fixedly connected to the bottom of the front of the furnace body 100 and is connected to the inner cavity of the furnace body 100. A filter screen 102 is fixedly installed inside the air inlet 101. Multiple first heat-conducting baffles 110 are also included. The first heat-conducting baffle 110 is fixedly fitted onto the outer wall of the exhaust pipe 109 from top to bottom, and its outer peripheral wall is fixed to the inner wall of the furnace body 100. Two adjacent first heat-conducting baffles 110 are staggered left and right, dividing the inner cavity of the furnace body 100 into a labyrinthine air intake channel. Multiple second heat-conducting baffles 111 are fixedly connected to the inner wall of the exhaust pipe 109 from top to bottom, with two adjacent second heat-conducting baffles 111 staggered front and back, dividing the inner cavity of the exhaust pipe 109 into a labyrinthine air outlet channel. Because the top of the exhaust pipe 109 seals the bottom of the catalyst support 103, ... Organic waste gas enters the furnace body 100 through the inlet 101, is transported upwards, and then flows downwards into the catalyst support 103. The exhaust gas, after reaction on the catalyst support 103, flows downwards through the exhaust pipe 109 and exits the furnace body 100 through the exhaust port 108. This avoids direct contact between the organic waste gas and the treated exhaust gas. Furthermore, the exhaust pipe 109, the first thermally conductive baffle 110, and the second thermally conductive baffle 111 are all made of excellent thermally conductive materials. The staggered arrangement of the first thermally conductive baffle 110 creates a labyrinthine air intake channel with multiple bends within the furnace body 100. The two heat-conducting baffles 111 create a labyrinthine exhaust channel with multiple bends inside the exhaust pipe 109. This extends the transport path of the organic waste gas and the treated tail gas within the furnace body 100. The heat in the treated tail gas is transferred to the exhaust pipe 109, the first heat-conducting baffle 110, and the second heat-conducting baffle 111, and then transferred through the exhaust pipe 109, the first heat-conducting baffle 110, and the second heat-conducting baffle 111 to the organic waste gas entering the furnace body 100. This allows the treated tail gas to be recovered and converted, preheating the organic waste gas and improving the utilization rate of thermal energy.

[0053] Example 2: Based on Example 1, the explosion-proof pressure relief mechanism further includes an explosion-proof leak pipe 106 and a pressure component. The explosion-proof leak pipe 106 is fixedly connected to the top of the furnace body 100, and the pressure component is disposed inside the explosion-proof leak pipe 106. When the pressure inside the explosion-proof leak pipe 106 reaches a preset threshold, the pressure component releases and reduces pressure. The explosion-proof leak pipe 106 is installed on the furnace body 100 so that when the pressure inside the furnace body 100 is too high, the pressure component can be opened, and the gas inside the furnace body 100 is discharged through the explosion-proof leak pipe 106, thus reducing pressure inside the furnace body 100 and avoiding the risk of explosion due to excessive pressure inside the furnace body 100, thereby enhancing the safety of the furnace body 100.

[0054] The pressure assembly includes a sealing plate 113, a pressure relief pipe 112, and a piston plate 114. The sealing plate 113 is fixedly connected to the bottom of the inner cavity of the explosion-proof leakage pipe 106. The pressure relief pipe 112 is fixedly connected to the middle of the top of the sealing plate 113 and communicates with the bottom of the sealing plate 113. A leakage port 117 is provided at the bottom of the outer peripheral wall of the pressure relief pipe 112. The piston plate 114 is slidably inserted into the pressure relief pipe 112. A pressure element is provided on the piston plate 114 to apply downward pressure to the piston plate 114. The pressure element includes a column 115 and at least one weight-adding plate 116. The column 115 is fixedly connected to the middle of the top of the piston plate 114. At least one weight-adding plate 116 is stacked on the top of the piston plate 114 and movably inserted into the outer wall of the column 115. The top of the column 115 is provided with a downwardly extending extension. The expansion cavity 119 has a conductive insert 121 fixedly connected to its bottom and a guide rod 118 movably inserted into its top. A plug-in switch 120 is fixedly embedded at the bottom of the guide rod 118. A buzzer alarm 124 is fixedly installed on the outer wall of the explosion-proof leakage pipe 106. The plug-in switch 120 is electrically connected to the buzzer alarm 124, so that the conductive insert 121 and the plug-in switch 120 form a power supply path for the buzzer alarm 124. A connecting rod 122 is fixedly connected to the top of the guide rod 118 and a crossbeam 123 is fixedly connected to the top of the inner wall of the explosion-proof leakage pipe 106. The outer wall of the connecting rod 122 is movably inserted into the middle of the crossbeam 123. An elastic compression spring 125 is provided between the crossbeam 123 and the guide rod 118 and is movably sleeved on the outer wall of the connecting rod 122.In this embodiment, the sealing plate 113 seals the inner cavity of the explosion-proof leakage pipe 106, so that gas can only enter the explosion-proof leakage pipe 106 through the bottom port of the pressure relief pipe 112 and the leakage port 117 on the side wall, and then be discharged from the top port of the explosion-proof leakage pipe 106. The piston plate 114, together with the weight-adding plate 116, can not only seal the bottom port of the pressure relief pipe 112, but also adjust the pressure required to push the piston plate 114 upward according to specific needs, so that the number and weight of the weight-adding plates 116 on the piston plate 114 can be adjusted according to the furnace body 1. The specifications and material properties of the furnace body 100 are adjusted. When the pressure inside the furnace body 100 exceeds the pressure on the piston plate 114, the piston plate 114 is pushed upward, connecting the leakage port 117 to the bottom port of the pressure relief pipe 112. At this time, the gas inside the furnace body 100 is discharged through this channel. When the pressure is high, the distance the piston plate 114 is pushed upward increases, thus increasing the opening width of the leakage port 117 and increasing the airflow in the explosion-proof leakage pipe 106, achieving automatic adjustment of pressure relief. Furthermore, when the pressure is about to reach the furnace body 100 material... When the pressure reaches the critical explosion-proof value, the piston plate 114 is pushed by the pressure to a position above the leakage port 117, the leakage port 117 is fully open, and the piston plate 114 is higher than the top of the leakage port 117. At this time, due to the upward movement of the column 115, the conductive insert 121 is inserted into the slot at the bottom of the insert switch 120, so that the insert switch 120 reaches the closed state. In this way, the buzzer alarm 124 is in the open state and sounds an alarm, prompting the staff to intervene manually; and the pressure inside the furnace body 100 further increases. When the column 115 moves further upward, it can also drive the guide rod 118 to move upward. During this process, the elastic spring 125 is compressed and deformed, which drives the guide rod 118 to keep the column 115 pressed together. This ensures a stable closed state between the plug-in switch 120 and the conductive plug 121. The alarm is only deactivated when the pressure drops and the column 115 moves downward until the conductive plug 121 is disengaged from the plug-in switch 120. This allows for timely monitoring of whether the pressure inside the furnace 100 has dropped to a safe range during manual intervention.

[0055] A method for treating organic waste gas, using an organic waste gas treatment device as described in the above embodiments, includes the following steps:

[0056] Step 1: Organic waste gas is pumped into the furnace body 100 through the inlet 101. Heating by the electric heating rod 104 and the active micro-points on the catalyst surface of the catalyst holder 103 lower the activation energy of the oxidation reaction of harmful substances in the organic waste gas, causing combustion in a low-temperature environment, thus converting it into harmless carbon dioxide and water vapor. The reacted gas enters the exhaust pipe 109 and is discharged towards the exhaust port 108. During this process, as the organic waste gas enters the furnace body 100 and is transported upwards, multiple first heat-conducting baffles 110 form multiple bends within the furnace body 100. The labyrinthine air intake channel extends the air intake path, allowing the organic waste gas to fully contact the first heat-conducting baffle 110 and the exhaust pipe 109. At the same time, when the treated gas flows downward in the exhaust pipe 109, multiple second heat-conducting baffles 111 form a multi-bend labyrinthine air outlet channel in the exhaust pipe 109, so that the heat in the treated exhaust gas can be transferred to the heat storage and heat exchange mechanism composed of the exhaust pipe 109, the first heat-conducting baffle 110 and the second heat-conducting baffle 111, thereby preheating the incoming organic waste gas, reducing the energy consumption of the electric heating rod 104, and utilizing the heat energy of the exhaust gas.

[0057] Step Two: During the exhaust gas treatment process inside the furnace body 100, if the pressure inside the furnace body 100 reaches the preset explosion-proof pressure threshold, the gas pressure will push the piston plate 114 with the weight-increasing plate 116 upward along the inner cavity of the pressure relief pipe 112, causing the leakage port 117 to partially connect with the lower part of the sealing plate 113, allowing some gas to be discharged from the explosion-proof leakage pipe 106 to the outside of the furnace body 100. Furthermore, the upward movement distance of the piston plate 114 is automatically adjusted according to the pressure inside the furnace body 100, thereby controlling the opening and closing range of the leakage port 117. If the pressure is too high and the piston plate 114 moves up to the position above the leakage port 117, the conductive insert 121 and the insert switch 120 at the bottom of the guide rod 118 will be connected to form a plug-in conductive state, which will power on the buzzer alarm 124 to generate an alarm and provide a warning. As the sealing plate 113 continues to move up, the column 115 will push the guide rod 118 and drive the guide rod 118 to move up. The elasticity of the elastic spring 125 will form a buffer distance to ensure the continuous alarm of the buzzer alarm 124 and reserve reaction time.

A conductive insert (121) is fixedly connected to the bottom of the telescopic cavity (119). A guide rod (118) is movably inserted into the top of the telescopic cavity (119). A plug-in switch (120) is fixedly embedded at the bottom of the guide rod (118). A buzzer alarm (124) is fixedly installed on the outer wall of the explosion-proof leakage pipe (106). The plug-in switch (120) is electrically connected to the buzzer alarm (124), so that after the conductive insert (121) and the plug-in switch (120) are inserted, a power supply path is formed to power the buzzer alarm (124). A connecting rod (122) is fixedly connected to the top of the guide rod (118), and a crossbeam (123) is fixedly connected to the top of the inner wall of the explosion-proof leakage pipe (106). The outer wall of the connecting rod (122) is movably inserted into the middle of the crossbeam (123). An elastic compression spring (125) is provided between the crossbeam (123) and the guide rod (118) and is movably sleeved on the outer wall of the connecting rod (122).

9. The organic waste gas treatment equipment according to claim 1, characterized in that, The furnace body (100) is provided with an insulation layer (105) inside, and an inspection port (107) is provided at the top of the outer wall of the furnace body (100) corresponding to the catalytic combustion mechanism.

10. A method for treating organic waste gas, characterized in that, The application of an organic waste gas treatment device as described in any one of claims 1-9 includes the following steps: Step 1: Organic waste gas is pumped into the furnace body (100) through the inlet (101). Heating by the electric heating rod (104) and the active micro-points on the catalyst surface of the catalyst support (103) reduce the activation energy of the oxidation reaction of harmful substances in the organic waste gas, causing the organic waste gas to undergo combustion in a low-temperature environment, thereby converting it into harmless carbon dioxide and water vapor. The reacted gas enters the exhaust pipe (109) and is discharged towards the exhaust port (108). During this process, as the organic waste gas enters the furnace body (100) and is transported upwards, multiple first heat-conducting baffles (110) form multiple bends within the furnace body (100). The labyrinthine air intake channel extends the air intake path, allowing the organic waste gas to fully contact the first heat-conducting baffle (110) and the exhaust pipe (109). At the same time, when the treated gas flows downward in the exhaust pipe (109), multiple second heat-conducting baffles (111) form a multi-bend labyrinthine air outlet channel in the exhaust pipe (109), so that the heat in the treated exhaust gas can be transferred to the heat storage and heat exchange mechanism composed of the exhaust pipe (109), the first heat-conducting baffle (110), and the second heat-conducting baffle (111), thereby preheating the incoming organic waste gas, reducing the energy consumption of the electric heating rod (104), and utilizing the heat energy of the exhaust gas. Step 2: When performing tail gas treatment in the furnace body (100), if the pressure inside the furnace body (100) reaches the preset explosion-proof pressure threshold, the gas pressure will push the piston plate (114) with the weight-increasing plate (116) upward along the inner cavity of the pressure relief pipe (112), so that the leak port (117) is partially connected to the bottom of the sealing plate (113), allowing some gas to be discharged from the explosion-proof leak pipe (106) to the outside of the furnace body (100). The upward movement distance of the piston plate (114) is automatically adjusted according to the pressure inside the furnace body (100) to control the opening and closing range of the leak port (117). If the pressure is too high and the piston plate (114) moves up to the position above the leakage port (117), the conductive insert (121) and the insert switch (120) at the bottom of the guide rod (118) will form a plug-in conductive state, which will power on the buzzer alarm (124) to generate an alarm and provide a warning. As the sealing plate (113) continues to move up, the column (115) will push the guide rod (118) and drive the guide rod (118) to move up. The elastic spring (125) will form a buffer distance to ensure the continuous alarm of the buzzer alarm (124) and reserve reaction time.
