It should be understood that the specific examples described herein are only used to explain the utility model and do not limit the application.
[0043] As shown in the figure, the utility model provides an energy-saving waste gas treatment system, comprising: a incinerator, a air mixing box 6, a heat exchanger 8 and a chimney 12; the incinerator comprises a combustion chamber, a heat storage chamber and a temperature control unit 2 for controlling the temperature of the incinerator; the air mixing box 6 is communicated with the combustion chamber through a combustion chamber pipeline, communicated with the heat storage chamber through a heat storage chamber pipeline, and communicated with the chimney 12 through the heat exchanger 8, and the chimney 12 is provided with a VOC online monitoring unit 11 at the end; the waste gas to be treated flows into the heat storage chamber through the air inlet pipeline 1, and flows to the combustion chamber through the heat storage chamber for combustion to generate combustion gas and regeneration gas; the combustion gas flows into the air mixing box 6 through the combustion chamber pipeline; the regeneration gas flows into the heat storage chamber and flows into the air mixing box 6 through the heat storage chamber pipeline; the combustion gas and the regeneration gas are mixed in the air mixing box 6 to generate mixed gas; the mixed gas flows to the heat exchanger 8 through the pipeline, and after heat exchange in the heat exchanger 8, it flows to the chimney 12 and is discharged.
[0044] In the embodiment, the VOC online monitoring unit 11 and the temperature control unit 2 work cooperatively to realize dynamic adjustment of waste gas emission. When the concentration of pollutants in the chimney 12 is higher than the set value, the VOC online monitoring unit 11 feeds back a signal to the temperature control unit 2, and the temperature control unit 2 automatically increases the temperature of the combustion chamber to enhance the waste gas decomposition effect, so as to achieve the purpose of reaching the emission standard; when the concentration is lower than the set value, the temperature control unit 2 reduces the combustion temperature to reduce fuel consumption, so as to realize energy-saving operation. The real-time adjustment mechanism effectively balances the relationship between waste gas treatment efficiency and energy consumption, and ensures that the system can stably operate under different working conditions.
[0045] It should be noted that the point of the utility model is the movement path and connection relationship between different treatment units. The inlet pipeline 1, the regenerative chamber, the combustion chamber and the air mixing box 6 are sequentially connected through pipelines and flow through the heat exchanger 8, and a feedback channel is provided through the VOC online monitoring unit 11 arranged at the end of the exhaust pipe, so that the continuity and efficiency of waste gas treatment are ensured; however, the temperature adjustment function between the VOC online monitoring unit 11 and the temperature control unit 2 belongs to the prior art, and the innovation point of the system is concentrated on the optimization of the overall structure, rather than the specific monitoring method or determination logic.
[0046] In the embodiment, the waste gas to be treated enters the regenerative chamber through the inlet pipeline 1, is preheated by the recovered high-temperature waste heat and then is sent into the combustion chamber. In the combustion chamber, the waste gas is efficiently decomposed into combustion gas and regeneration gas. The combustion gas is transported to the air mixing box 6 through the combustion chamber pipeline, is mixed with the backflow regeneration gas to form mixed gas, and then enters the heat exchanger 8 for heat exchange. The low-temperature waste gas after heat exchange is discharged through the chimney 12, and the waste heat is transferred to the heat utilization device 10 through the heat exchanger 8, so that the heat is recycled. In addition, the setting of the air mixing box 6 can effectively reduce the thermal shock of high-temperature flue gas on the heat exchanger 8, prolonging the service life of the equipment.
[0047] In an embodiment of the application, the temperature control unit 2 is connected in communication with the VOC online monitoring unit 11, the VOC online monitoring unit 11 monitors the concentration of waste gas in the chimney 12, and the temperature in the combustion chamber is increased or decreased through the temperature control unit 2.
[0048] In the embodiment, the temperature control unit 2 dynamically adjusts the temperature in the combustion chamber based on the hourly average concentration value fed back by the online monitoring system. When the concentration of pollutants fluctuates greatly, the temperature control unit 2 can adjust the combustion temperature in advance to avoid the situation that the emission does not reach the standard due to excessive concentration. At the same time, the adjustment mechanism can appropriately reduce the temperature when the concentration is low to reduce energy consumption. Through this accurate and stable regulation and control mode, the system always operates in an efficient and low-consumption state.
[0049] In an embodiment of the application, a first temperature sensor 3 is arranged in the combustion chamber.
[0050] In this embodiment, the first temperature sensor 3 installed in the combustion chamber works in coordination with the temperature control unit 2 to achieve real-time monitoring and adjustment of the combustion chamber temperature. The sensor continuously acquires temperature data inside the combustion chamber and feeds back the data to the temperature control unit 2, which adjusts the operating conditions of the combustion chamber in a timely manner based on these data, thereby optimizing the combustion efficiency and ensuring the efficient and safe operation of the system.
[0051] In an embodiment of the present application, the combustion chamber is connected to the air mixing box 6 through the first valve 4, and the second temperature sensor 5 is installed on the pipeline connecting the heat exchanger 8 to the chimney 12.
[0052] In this embodiment, the first valve 4 between the combustion chamber and the air mixing box 6 is connected to the second temperature sensor 5 at the outlet of the heat exchanger 8. When the outlet temperature of the heat exchanger 8 approaches the design threshold, the opening of the first valve 4 is automatically reduced to reduce the delivery amount of high-temperature flue gas, thereby avoiding thermal shock to the heat exchanger 8. At the same time, the temperature sensor monitors the temperature changes at both ends of the combustion chamber and the heat exchanger 8 in real time, ensuring the dynamic balance of the heat transfer process and further optimizing the thermal energy utilization efficiency of the system.
[0053] In an embodiment of the present application, the first valve 4 is connected in communication with the second temperature sensor 5, and the first valve 4 controls the opening and closing ratio of the valve based on the second temperature sensor 5.
[0054] In this embodiment, the first valve 4 is an electric proportional high-temperature valve. When the outlet temperature of the heat exchanger 8 approaches the preset threshold, the opening of the first valve 4 will automatically adjust to reduce its opening, thereby reducing the inflow of high-temperature flue gas. This automatic adjustment mechanism aims to avoid thermal shock to the heat exchanger 8 caused by high-temperature flue gas and reduce the risk of damage that may occur during long-term operation. In addition, the second temperature sensor 5 continuously monitors the temperature changes between the combustion chamber and the heat exchanger 8, ensuring that the temperature changes at both ends are in a controlled state, thereby ensuring the dynamic balance of the heat transfer process. This balance not only protects the equipment but also improves the thermal energy utilization efficiency of the entire system, achieving higher performance operation.
[0055] In an embodiment of the present application, the air mixing box 6 is internally provided with a third temperature sensor 9.
[0056] In this embodiment, a third temperature sensor 9 is installed inside the mixing box 6. The core of this design is to monitor the temperature changes in the mixing box 6 in real time, ensuring that the system can effectively manage the mixing of combustion gases and regenerative gases in the regenerator. The role of the mixing box 6 is to effectively mix the high-temperature combustion gases from the combustion chamber with the regenerated gases in the regenerator to optimize the overall thermal energy utilization efficiency. By introducing a temperature sensor in the mixing box 6, the temperature of the mixed gases can be accurately monitored to ensure that it is within an acceptable range, which is crucial for ensuring the safety and stability of gas mixing. Real-time temperature monitoring can help adjust the mixing ratio and optimize the combustion process, thereby improving the energy use efficiency of the system.
[0057] In an embodiment of the present application, the second valve is communicatively connected to the third temperature sensor 9, and the second valve controls the opening and closing ratio of the valve based on the third temperature sensor 9.
[0058] In this embodiment, the connection between the second valve and the third temperature sensor 9 realizes the function of intelligent control. The opening and closing ratio of the second valve is determined based on the real-time temperature data provided by the third temperature sensor 9 (the temperature inside the mixing box 6). Although this communication and judgment method is a prior art, the innovation point in this embodiment lies in its specific connection relationship. Specifically, the opening degree of the valve dynamically reflects the temperature changes inside the mixing box 6 to optimize the gas flow to the heat exchanger 8. When the third temperature sensor 9 detects that the temperature inside the mixing box 6 approaches the set threshold, the second valve automatically adjusts the opening degree, thereby optimizing the gas flow. This mechanism not only improves the combustion efficiency, but also effectively avoids safety hazards caused by excessive temperature. With the real-time feedback of the third temperature sensor 9, the entire system can maintain a stable combustion process under various working conditions, improving response speed and operational flexibility.
[0059] In an embodiment of the present application, it further includes a three-way valve 7, the first end of the three-way valve 7 is in communication with the mixing box 6, the second end of the three-way valve 7 is in communication with the chimney 12 through a standby pipeline, and the third end of the three-way valve 7 is connected to the heat exchanger 8; the three-way valve 7 further includes a flow control part to control the gas flow of the second end and the third end.
[0060] In this embodiment, the first end of the three-way valve 7 is connected to the mixing box 6. The design is to realize the flexible switching and management of the mixed gas generated by the mixing box 6 and other fluids. The second end of the three-way valve 7 is connected to the chimney 12 through a standby pipeline, and the third end is connected to the heat exchanger 8. Through this setting, the three-way valve 7 can control the gas flow to the heat exchanger 8 or the chimney 12. The three-way valve 7 is also equipped with a flow control part, which is used to accurately adjust the gas flow into the second end and the third end, so that the system can adjust the flow of gas according to the actual demand.
[0061] Further, in order to realize the joint control of the second end and the third end, the three-way valve 7 is an electric linkage three-way valve 7, in which an electric linkage switch is arranged, which can synchronously adjust the opening and closing degrees of the two ports. The advantage of this design is that it can reduce system complexity, improve operation convenience and reliability while meeting operational requirements.
[0062] More preferably, the standby pipeline is connected with the chimney 12 through the three-way valve 7 and is linked with the heat exchanger 8 through the electric linkage switch. The electric linkage switch is designed to ensure that the opening and closing states of the standby pipeline and the heat exchanger 8 are completely synchronized, and the opening and closing angles are consistent. The fundamental reason for this design is to ensure the balance of fluid pressure and the stability of air flow direction in the system to avoid air flow problems caused by inconsistent states.
[0063] Specifically, after the flue gas enters the three-way valve 7 from the air mixing box 6, it will face two outlet paths (the standby pipeline and the heat exchanger 8), and the distribution of the air flow directly depends on the opening and closing of the two pipelines. If the opening degrees or angles of the two pipelines are not synchronized, the following problems may occur: first, the air flow will preferentially enter the side with smaller resistance, thereby disturbing the original designed fluid distribution of the system, resulting in reduced heat exchange efficiency or failure of the standby function; second, the asynchronization may form a backflow or uneven pressure in one of the pipelines, and even cause vibration or damage of the pipeline system. In addition, in some cases, the sudden change of the direction of gas flow may also cause safety risks.
[0064] To avoid the above problems, the electric linkage switch is designed to synchronize the opening and closing of the standby pipeline and the heat exchanger 8 and make the opening and closing angles consistent, which can ensure that the distribution and flow direction of the gas between the two pipelines meet the system design requirements whether it is a mode switching or a normal working state. Especially in special working conditions (such as high-temperature emission or equipment maintenance), the synchronous control of the linkage switch can also avoid pipeline failures caused by improper human operation. Ultimately, this design not only simplifies the adjustment process, but also guarantees the overall stability and safety of the system operation.
[0065] In an embodiment of the present application, a heat utilization device 10 is further included, and the heat exchanger 8 is connected with the heat utilization device 10. The heat of the exhaust gas discharged from the air mixing box 6 is provided to the heat utilization device 10 after heat exchange in the heat exchanger 8.
[0066] In this embodiment, the heat device 10 is coupled with the flue gas discharged from the air mixing box 6 through the heat exchanger 8. The principle is that when the flue gas discharged from the air mixing box 6 passes through the heat exchanger 8, the heat in the flue gas is effectively transferred to the heat transfer medium of the heat exchanger 8 through heat conduction or heat convection. The heat in the heat exchanger 8 is further transferred and transmitted to the heat device 10, realizing the recovery and utilization of flue gas waste heat. The significance of this design is to maximize the use of heat energy in the flue gas, improve the energy utilization efficiency of the system, and reduce the waste of heat energy. In the use scenario, the heat device 10 can be a device that requires a stable heat source, such as a heating reactor, a heating system, or a steam generator, etc., so this heat transfer mode through the heat exchanger 8 not only avoids the environmental impact of direct flue gas discharge, but also provides a safe heat source guarantee for the operation of the heat device 10. By coupling the high-temperature flue gas discharged from the air mixing box 6 with the heat device 10, the heat exchanger 8 realizes the step-by-step transfer of energy.
[0067] Further, after the heat exchanger 8 transfers the heat in the flue gas to the heat device 10 through an efficient heat exchange process, the treated low-temperature flue gas (ensuring that the flue gas temperature is higher than its dew point temperature) is safely discharged to the chimney 12. The key to this process is to maintain the flue gas temperature appropriately to avoid condensation of low-temperature flue gas due to cooling to the dew point temperature, which can effectively prevent water condensation in the pipeline, thereby reducing the risk of pipeline corrosion and reducing potential equipment failures. By discharging the low-temperature flue gas after heat exchange to the chimney 12, not only can the overall thermal efficiency of the system be improved, but also the greenhouse gas emissions can be reduced, meeting environmental protection standards, while ensuring the safety and reliability of the system during operation.
[0068] In an embodiment of the present application, the heat storage chamber comprises a plurality of cavities.
[0069] In this embodiment, the plurality of cavities are used to improve the performance of heat energy storage and release, and provide flexible operation control capability. The plurality of cavities are separated by partitions or special materials, which decompose the large heat capacity into independent or interconnected heat energy units, so as to adjust the heat energy distribution according to the demand. For example, in the case of large demand fluctuations, part of the cavities can be put into work while the other cavities are temporarily insulated. At the same time, the design of the plurality of cavities helps the heat flow to pass through one by one, each cavity to cool down gradually, effectively utilizing the heat energy. This structure also improves the reliability of the system, as a fault or degraded cavity will not affect the overall operation. Through these designs, the system can more flexibly adapt to different heat energy demand conditions, and show higher operation efficiency in heat energy storage and performance adjustment.
[0070] In summary, the utility model provides a kind of energy -conserving waste gas treatment system, integrated incinerator, mixes wind box, heat exchanger and chimney. By air intake pipeline, the waste gas to be treated is transported to heat storage room after heating and enters combustion chamber, and the combustion gas generated is mixed with the backflow regenerative gas in the air mixing box, then heat exchange is carried out through the heat exchanger, and finally discharged. Natural gas flow meter is provided on temperature control unit to measure the consumption of natural gas. Temperature control unit monitors in real time and intelligently adjusts the temperature of combustion chamber, ensures sufficient treatment of waste gas, thereby improves the processing efficiency and reduces energy consumption, thereby effectively solves the problems of low waste gas treatment efficiency, high energy consumption and emission in prior art. Through the combination of dynamic monitoring and temperature control, the temperature control precision and pollutant removal rate are improved, and the waste gas flow and heat energy recovery mechanism are optimized. In practical application, the waste gas treatment efficiency is significantly improved, the pollutant emission is reduced, the win-win of economic benefit and environmental protection is realized, and good application potential and industrial value are possessed.
