Description

Technical Field

[0001] This application relates to the technical field of waste gas RTO combustion devices, and in particular to an organic waste gas RTO combustion device for removing odors. Background Technology

[0002] An organic waste gas combustion device is a highly efficient organic waste gas treatment equipment. It is mainly used to treat waste gas containing organic pollutants generated during industrial production processes, such as volatile organic compound waste gas generated in industries such as chemical, coating, and printing. The RTO device converts harmful substances in organic waste gas into harmless substances such as carbon dioxide and water through combustion. Its core principle is to use the heat storage and heat release characteristics of the heat storage body to preheat the incoming waste gas, so that the waste gas can be fully combusted in a high-temperature environment.

[0003] A search revealed Chinese patent application CN202420026049.3, which discloses a high-efficiency RTO (Regenerative Thermal Oxidizer) device for treating organic waste gas. The device includes a regenerative combustion furnace with three equidistant regenerative chambers inside. A combustion chamber is located at the top of each of the three regenerative chambers. A pipe assembly is located at the bottom of the furnace, and an air intake fan is fixedly installed on top of the assembly. A waste gas outlet pipe is fixedly connected to the rear end of the air intake fan, and a preheating mechanism is fixedly connected to the front end of the fan. A connecting pipe is fixedly connected to the left end of the preheating mechanism. A secondary air purification filtration mechanism is located on the right side of the furnace. This mechanism utilizes the heat generated by the preheater to transfer heat to the organic waste gas requiring heating, preventing condensation of the waste gas at the bottom of the RTO in cold weather such as winter. The air purification filtration mechanism further cleans any secondary pollutants (dioxins) or low-concentration waste gas that may be generated after RTO treatment.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: During use, the exhaust gas flow rate is typically unstable during combustion. When the exhaust gas flow rate changes, if the burner flame propagation speed remains constant, combustion mismatch will occur. When the flow rate is low, the flame is relatively too large, resulting in excess fuel combustion without sufficient exhaust gas to react with it. This not only wastes fuel but may also lead to excessively high local temperatures, adversely affecting the equipment. Conversely, when the exhaust gas flow rate is high, the flame is too small, and the exhaust gas cannot be fully combusted, causing the combustion temperature to fall short of requirements, resulting in reduced combustion efficiency. The discharge of incompletely combusted exhaust gas will also cause environmental pollution. Utility Model Content

[0014] In summary, this application includes the following beneficial technical effects:

[0015] 1. This utility model, by setting up a pressure air pump, a squeezing block, a trigger plate, a top pressure spring, and an adjusting valve regulating box, enables the pressure air pump to discharge pressurized waste gas into the regulating box, which squeezes the squeezing block, causing it to move upward inside the regulating box. When the air pressure increases, the trigger plate squeezes the adjusting valve, thereby increasing the valve's control valve size and causing the flame to increase accordingly. This allows the flame to be adjusted according to the changes in the flow of waste gas, enabling the fuel and organic matter in the waste gas to be matched for combustion, thus improving combustion efficiency.

[0016] 2. By setting up components such as an exhaust pipe and a recovery mechanism, after combustion, the combustion gas is discharged from the exhaust pipe into the interior of the heat insulation box. The heat of the discharged gas will come into contact with the heat-conducting fins, and the heat will be conducted to the linkage pipe through the heat-conducting fins. This can achieve preheating of the gas that has just been discharged from the combustion box, realize the secondary utilization of the heat of the discharged gas, and thus improve energy utilization efficiency.

[0022] The following is in conjunction with the appendix Figure 1 —4. This application will be described in further detail.

[0023] This application discloses an RTO combustion device for deodorizing organic waste gas. For example... Figure 1 As shown, the device includes a pressure air pump 1, a filter mechanism 2 at the input end of the pressure air pump 1, an adjustment box 3 fixedly connected to the output end of the pressure air pump 1, a linkage pipe 4 fixedly connected to one side of the adjustment box 3, a combustion box 5 fixedly connected to the upper end of the linkage pipe 4, a pressing block 6 slidingly fitted on the inner wall of the adjustment box 3, a trigger plate 7 fixedly connected to the upper side of the pressing block 6, and a top pressure spring 8 fixedly connected between the pressing block 6 and the adjustment box 3. The top pressure spring 8 is used to reset the pressing block 6 after it is no longer under pressure.

[0024] Please see Figure 4Two connecting blocks 15 are fixedly connected to the upper side of the filter plate 203. Each connecting block 15 is provided with a bolt 16 that cooperates with the filter box 201. The bolt 16 passes through the connecting block 15 and connects with the filter box 201, thereby fixing the filter plate 203. The filter plate 203 can be replaced or cleaned by rotating the bolt 16 in the opposite direction.

[0025] Please see Figure 1 Multiple collars 14 are fixedly connected to the outside of the combustion chamber 5. The collars 14 are bonded to the combustion chamber 5 with heat-insulating adhesive. The heat-insulating adhesive reduces heat conduction, and the collars 14 protect the outside of the combustion chamber 5, reducing accidental contact between the combustion chamber 5 and the human body and improving safety.

[0026] An adjustment valve 9 is provided on one side of the inner wall of the adjustment box 3, which cooperates with the trigger plate 7. The output end of the adjustment valve 9 is fixedly connected to a fuel pipe 10 that penetrates to the inner wall of the combustion box 5. The output end of the fuel pipe 10 is fixedly connected to a flame head 11. An exhaust pipe 12 is provided on one side of the combustion box 5. A recovery mechanism 13 located outside the linkage pipe 4 is provided at the output end of the exhaust pipe 12.

[0027] Please see Figure 2 and Figure 4 The filtration mechanism 2 includes a filter box 201 fixedly connected to the input end of the pressure air pump 1, an insertion interface 202 opened on the upper side of the filter box 201, a filter plate 203 fixedly connected to the inner wall of the insertion interface 202, and an air inlet 204 fixedly connected to one side of the filter box 201. The air inlet 204 is connected to the corresponding air inlet end. The pressure air pump 1 draws the gas, and the gas passes through the filter plate 203 to filter particulate matter and some gaseous pollutants in the exhaust gas, thereby reducing the odor of subsequent combustion.

[0028] Please see Figure 2 The recovery mechanism 13 includes an insulation box 131 fixedly connected to the outside of the linkage pipe 4, heat-conducting fins 132 fixedly connected to the outside of the linkage pipe 4, an exhaust pipe 133 fixedly connected to one side of the insulation box 131, and the output end of the exhaust pipe 12 extends into the interior of the insulation box 131. When the gas is discharged from the exhaust pipe 12 into the insulation box 131, the temperature of the gas will come into contact with the heat-conducting fins 132, thereby heating the exhaust pipe 12 and preheating the gas flowing inside the exhaust pipe 12, thus realizing heat recovery and utilization.

[0029] Please see Figure 3 A reset spring 17 is fixedly connected to the regulating valve 9. The upper end of the reset spring 17 is fixed to the upper side of the inner wall of the regulating box 3. When the trigger plate 7 is separated from the regulating valve 9, the reset spring 17 will press the regulating valve 9 downward, so that the regulating valve 9 is reset and the valve is reduced.

[0030] Please see Figure 1 The heat insulation box 131 has a cleaning port 18 on the front side. A sealing plate 19 is fixedly connected to the inner wall of the cleaning port 18. The sealing plate 19 and the cleaning port 18 are detachably fixedly connected. The inner wall of the heat insulation box 131 can be cleaned by removing the sealing plate 19 to prevent dust from affecting its thermal conductivity.

[0031] The implementation principle of the organic waste gas RTO combustion device for removing odors in this application embodiment is as follows: When in use, the organic waste gas tail gas is connected through the air inlet 204 of the filter box 201. The pressure pump 1 draws air into the filter box 201, so that the waste gas passes through the filter plate 203 on the inner wall of the insertion interface 202. The waste gas is filtered by the filter plate 203 to reduce the particles in the gas, avoid the odor generated by the subsequent combustion of particles, and improve stability.

[0032] Then, pressurized exhaust gas is discharged into the regulating box 3 via the pressure pump 1, which compresses the compression block 6, causing it to move upwards inside the regulating box 3. As the gas pressure increases, the compression block 6 moves upwards, driving the trigger plate 7 to compress the adjusting valve 9. This causes the adjusting valve 9 to increase its control valve size, resulting in a larger flame. This allows the flame to be adjusted according to the changes in the exhaust gas flow, enabling the fuel and organic matter in the exhaust gas to be matched for combustion, thus improving combustion efficiency.

[0033] After combustion, the combustion gases are discharged into the insulation box 131 through the exhaust pipe 12. The heat from the discharged gases comes into contact with the heat-conducting fins 132, which conduct heat to the linkage pipe 4. This allows the gases that have just been discharged from the combustion box 5 to be preheated, enabling the secondary utilization of the heat from the discharged gases and thus improving energy efficiency.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
