[0058] The parameters of the primary G4 filter are: filtration efficiency is 95%, and the air volume is 3000m 3 / h, size is 595×595×46mm, initial resistance is 40Pa, final resistance is 250Pa;
[0059] The medium efficiency filter is used to remove particles of 1 to 5 μm in the exhaust gas. When the resistance reaches the set value, it is taken out and replaced. It is used as a disposable product with a replacement cycle of about 2 months. The parameters of the F7 / F9 filter used in the medium efficiency filter are:
[0060] name Filtration efficiency <![CDATA[Processing air volume (m 3 / h)]]> Dimensions (mm) Dosage (sheets) Initial resistance (Pa) ACF 95 3000 595×595×600 28 600 F7 Filter 90% 3000 595×595×600 28 105 F9 Filter 90% 3000 595×595×600 28 105
[0061] The continuous adsorption module can effectively remove volatile organic compounds (VOCs) from exhaust gas through continuous adsorption and regeneration processes, thereby improving the exhaust gas purification effect.
[0062] In this embodiment, through three-stage filtration including primary filter G4, medium filter ACF, F7, and F9, the system can effectively remove particulate matter of different particle sizes in the exhaust gas, remove dust that is harmful to the rotor, and protect the rotor in the continuous adsorption module from damage, thereby improving the purification efficiency and extending the service life of the equipment; the filter is provided with a differential pressure gauge, which can alarm when overpressure is detected to ensure timely replacement of the filter material and avoid system performance degradation due to filter clogging; the primary filter is replaced every half a month and the medium filter is replaced approximately every two months to regularly replace the filter to reduce system downtime caused by filter clogging and reduce maintenance costs; the continuous adsorption module effectively removes volatile organic compounds (VOCs) in the exhaust gas through continuous adsorption and regeneration processes, thereby improving the exhaust gas purification effect, and at the same time, it is possible to improve energy efficiency by optimizing the adsorption and regeneration processes.
[0063] In a further embodiment, the catalytic combustion system includes a waste heat utilization module, a power equipment module, a catalytic combustion module, a control room module, and a tool box module.
[0064] The power equipment module, including fans, pumps, and motors, ensures that exhaust gas flows smoothly in the system and maintains the normal operation of each module.
[0065] The toolbox module provides the necessary tools and spare parts for the maintenance and overhaul of the RTO high temperature incineration system through a complete toolbox configuration, ensuring that when a failure occurs or maintenance is required, it can be handled quickly, reducing downtime and ensuring production continuity.
[0066] The catalytic combustion module burns the organic pollutants in the exhaust gas at high temperatures under the action of a catalyst, converting them into harmless carbon dioxide and water, ensuring that the organic pollutants are completely decomposed, reducing energy consumption and secondary pollution. Figure 2In this embodiment, two types of catalysts are used: precious metal composite rare earth oxide catalyst and rare earth composite oxide catalyst. The precious metal composite rare earth oxide catalyst has high activity and a broad spectrum of activity against various organic waste gases. The combustion is thorough and the CO 2 The selectivity reaches more than 98%; the coating is firm and the active components do not fall off; the service life is long, and its normal operating life is more than 3 years; the honeycomb and particle size and shape can be customized. The rare earth composite oxide catalyst has low cost and is lower than the precious metal catalyst on the market; the catalyst has high activity, especially for oxygen-containing and nitrogen-containing organic waste gases, the ignition temperature is less than 200 degrees; the catalyst burns thoroughly and has no effect on CO 2 The selectivity reaches over 99%; the coating is firm and the active components do not fall off; the honeycomb and particle size and shape can be customized.
[0067] The waste heat utilization module allows the high-temperature airflow generated by oxidation to flow through the ceramic heat storage body to store heat. When the waste gas containing organic matter enters the RTO high-temperature incineration system, it first flows through the ceramic heat storage body, which releases the stored heat to heat it up and "storage heat", preheating the waste gas to a temperature close to that required for the oxidation reaction, and then the preheated waste gas enters the combustion chamber. The preheating module can save fuel consumption caused by the temperature rise of the waste gas and improve energy utilization efficiency.
[0068] In this embodiment, two types of catalysts, namely precious metal composite rare earth oxide catalysts and rare earth composite oxide catalysts, are used to promote the oxidation rate of organic pollutants and improve the exhaust gas purification efficiency. Since the temperature required for catalytic combustion is relatively low, the thermal stress on the internal materials of the RTO system can be reduced and the service life of the equipment can be extended. The waste heat utilization module recovers and stores heat in the high-temperature airflow through a ceramic heat storage body, releases heat before the exhaust gas enters the combustion chamber, and preheats the exhaust gas to a temperature close to that required for the oxidation reaction, thereby reducing the additional fuel consumed to reach the reaction temperature. By preheating the exhaust gas, the use of fuel is reduced and the operating cost is reduced.
[0069] In a further embodiment, the control room module adopts a programmable controller system PLC, which is equipped with centralized control and local control. It is responsible for power supply and automatic control of various power equipment in the exhaust gas treatment facility, real-time monitoring of system operating status and parameters, and timely adjustment of control strategies to ensure safe, stable and efficient operation of the system.
[0070] The specific operations of centralized control are:
[0071] The operator starts the system at the PLC operation station in the central control room. After receiving the start command, the PLC starts the power equipment in sequence according to the preset start sequence.

[0073] Adjust the control parameters according to the monitoring data obtained, and the PLC automatically adjusts the operating status of the equipment according to the set parameters;
[0074] The PLC performs fault processing and system shutdown based on the detected fault;
[0075] The specific operations of local control are:
[0076] The operator issues a command on the control panel attached to the equipment, and the PLC starts the equipment after receiving the start command;
[0077] The operator directly adjusts the operating parameters of the equipment through the control panel, and the PLC responds and adjusts in real time and changes the operating status of the equipment;
[0078] The operator stops or shuts down the PLC controlled equipment by pressing the emergency stop button on the control panel.
[0079] In a further embodiment, the programmable controller system PLC mainly controls temperature, pressure, flow, level, and composition, specifically:
[0080] Temperature and pressure control adopts PID control algorithm, and the calculation formula is:
[0081]
[0082] Among them, u(t) is the output of the controller, e(t) is the error, that is, the difference between the set temperature and the actual temperature, the difference between the set pressure and the actual pressure, K p , K i , K d are the proportional, integral and differential coefficients respectively;
[0083] Flow control is achieved by adjusting the valve opening, and the calculation formula is:
[0084]
[0085] Among them, Q is the flow rate, C v is the valve flow coefficient, ΔP is the pressure difference on both sides of the valve;
[0086] Level control is carried out by adjusting the opening of the feed and discharge valves. The calculation formula is:
[0087] L=L 0 +∫Q in dt―∫Q out dt;
[0088] Among them, L is the current liquid level, L 0 is the initial liquid level, Q in is the feed flow rate, Q outis the discharge flow rate;
[0089] Composition control involves the balance of chemical reactions and the ratio of the mixture, calculated as:
[0090]
[0091] Where C is the concentration of the mixture component, m 1 , m 2 ,…,m n is the mass of each component and V is the total volume of the mixture.
[0092] The PLC system of this embodiment helps to optimize the combustion process by accurately controlling parameters such as temperature, pressure, and flow. Based on the real-time monitoring of parameters such as temperature and pressure, once an abnormal situation is detected, an alarm can be immediately issued and corresponding measures can be taken to prevent equipment damage or safety accidents. The PLC system can also monitor the operating status of the RTO system in real time, adjust control parameters in a timely manner, ensure stable operation of the system, avoid system failures caused by parameter fluctuations, and use the recorded data to analyze the system operating status to help maintenance personnel discover potential problems in a timely manner.
