Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of waste gas treatment, in particular to a multifunctional waste gas treatment device and system. BACKGROUND

[0002] Traditional waste gas is directly discharged into the air, but the direct discharge into the air will affect the surrounding environment.

[0003] In order to avoid the impact of waste gas on the surrounding environment, the waste gas needs to be treated when it is discharged. In the existing waste gas treatment technology, physical adsorption and chemical absorption are the two most widely used basic methods. Physical adsorption mainly relies on the high specific surface area characteristics of porous materials such as activated carbon and molecular sieve, and the pollutants such as VOCs and particulate matter in the waste gas are intercepted in the material pores. Chemical absorption is through alkaline solution (such as NaOH) or oxidizing agent (such as H2O2) to neutralize or oxidize the acidic gas (such as SO2, NOx) or reducing substance in the waste gas, and generate stable salt or harmless substance.

[0004] However, the existing waste gas treatment device mainly relies on single physical adsorption or chemical absorption, and has the problems of low degradation efficiency and limited treatment effect on volatile organic compounds (VOCs) and fine particulate matter, which leads to a large amount of carbon monoxide, nitrogen oxides and odor substances in the exhaust gas, seriously threatening air quality and human health. SUMMARY

[0005] The purpose of the present application is to provide a multifunctional waste gas treatment device and system, which aims to solve the problem of how to degrade the flue gas and volatile organic compounds after gasification.

[0012] This invention discloses a multifunctional waste gas treatment device and system. A large amount of ordinary air is mixed and diluted with the flue gas discharged from the degradation chamber via a flue gas distribution module. The mixture is then fed into a flue gas separation module, where organic particulate matter in the flue gas is removed by high-pressure spraying and centrifugal washing. The remaining carbon dioxide and volatile organic compounds (VOCs) undergo further water-gas separation via a molecular sieve module. The VOCs are then decomposed into carbon dioxide and water vapor by a VOCs treatment module. Residual ozone is further reduced to ordinary oxygen by an ozone reduction module. Finally, the large amount of mixed gas and the decomposed carbon dioxide are dispersed through an active ion pump in the exhaust box to activate the large amount of air emitted. This ensures that, apart from the diluted carbon dioxide, the majority of the emitted air still contains active oxygen. Thus, through multi-stage treatment modules, the gasified flue gas and volatile organic compounds can be effectively degraded. Attached Figure Description

[0030] The application provides a multifunctional waste gas treatment device, which comprises a flue gas air distribution module 101, an air distribution and spraying module 102, a flue gas and steam separation module 103, a molecular sieve module 104, a VOCs treatment module 105, an ozone reduction module 106, an exhaust module 107, a water treatment module 108, a fan cabin 109, an exhaust tank 110, a buffer plate 111 and an air distribution plate 112. The above-mentioned scheme solves the problem of how to degrade the gasified flue gas and volatile organic compounds, and can be understood that the above-mentioned scheme can be used in the case of needing to degrade the gasified flue gas and volatile organic compounds.

[0031] In the embodiment, the uniform air spraying module 102 is connected with the flue gas air distribution module 101, the flue gas and water vapor separation module 103 is connected with the uniform air spraying module 102, the molecular sieve module 104 is connected with the flue gas and water vapor separation module 103, the VOCs treatment module 105 is connected with the molecular sieve module 104, the ozone reduction module 106 is connected with the VOCs treatment module 105, the exhaust module 107 is connected with the ozone reduction module 106, the water treatment module 108 is connected with the uniform air spraying module 102, the flue gas air distribution module 101 is an air inlet for flue gas and air, the flue gas air distribution module 101 has two pipes, one for air and the other for flue gas, the air and the flue gas are mixed in the pipes, then enter the uniform air spraying module 102, the uniform air spraying module 102 has multiple spray heads for water washing the mixed flue gas, and has an air uniformizing plate 112 for slowing down the flow of the flue gas, so that the flue gas is more fully washed, then enters the flue gas and water vapor separation module 103, the flue gas and water vapor separation module 103 separates the water washed flue gas and water vapor, and has four centrifuges for effectively intercepting water vapor to prevent large water droplets from being sucked into the next processing link, the separated flue gas and water vapor then enter the molecular sieve module 104, the molecular sieve module 104 has two molecular sieves and a condensation net, when a small amount of water vapor enters the molecular sieve, the first molecular sieve can effectively intercept the water vapor, but the gas humidity is relatively high at this time, the second molecular sieve basically cannot pass water vapor, so that the relative humidity of the flue gas entering the condensation net is small, the condensation net further captures residual water, adsorbs a small amount of water vapor on the condensation net, and finally discharges flue gas with smaller humidity, then enters the VOCs treatment module 105, the VOCs treatment module 105 has four high-voltage electric fields, which can effectively generate high-concentration ozone by ionizing oxygen in the air, and can effectively decompose organic waste gas and harmful substances in the previous module, then enters the exhaust module 107, the exhaust module 107 has a flow disturbing device for mixing the passing gas again, then enters the fan bin, the fan bin is provided with an aluminum-based ozone reduction plate, which can efficiently reduce O3 generated by the VOCs treatment module 105 into oxygen and oxygen ions, effectively reducing the harm of ozone to the environment, then enters the exhaust module 107, the exhaust module 107 is the last processing unit to prevent and a small amount of untreated gas from being directly discharged into the atmosphere, the exhaust module 107 has a D activated carbon filter barrel with strong adsorption capacity, which can effectively capture VOCs and other harmful gas molecules, and six plasma generators are further provided to further decompose residual harmful substances and harmful components, and finally the discharged gas meets the environmental protection standard.

[0032] Wherein, the flue gas mixed with air enters the uniform air distribution spray module 102, through the double action of high-efficiency spray water washing and uniform air distribution plate 112, the deep purification of flue gas is realized. The spray water pressure is controlled at 5.5kg, ensuring uniform distribution of water mist, effectively capturing particulate matter and harmful substances in the flue gas. The angle between the spray water washing and the uniform air distribution plate 112 is designed to be 8.3°, this angle is optimized, which can maximize the gas-liquid contact efficiency, enhance the purification effect, in order to optimize the uniform distribution of mixed gas in the air distribution module, considering that its main components are air and carbon dioxide, and the density of carbon dioxide is significantly higher than that of air, under the action of gravity, carbon dioxide is easy to sink, leading to gas stratification phenomenon. To solve this problem, a baffle structure can be added at the bottom of the uniform air distribution plate 112, which can limit the sinking trend of carbon dioxide by physical barrier. At the same time, the negative pressure system design forcibly inhales air from the middle, which can effectively guide the mixed gas to flow upward, promote the full mixing of air and carbon dioxide, avoid local concentration too high or too low, so as to improve the uniformity of gas distribution and system operation efficiency. This optimization design not only solves the problem of gas stratification, but also enhances the stability and controllability of the system.

[0033] Secondly, the gas discharged by the uniform air distribution spray module 102 enters the centrifuge, under the action of high-speed centrifugation, large particles of water and hydrocarbon-based petroleum resin in flue gas are effectively separated and precipitated into the sewage tank. However, during the high-speed water-gas separation process, due to the limitation of the internal structure of the centrifuge, the effective area of the outlet is reduced, resulting in a significant increase in wind speed. This high-speed airflow cannot quickly and evenly fill the entire duct, causing uneven airflow distribution, which in turn affects the overall efficiency of the system. To solve this problem, the buffer plate 111 and the uniform air distribution plate 112 are added at the outlet of the centrifuge. The buffer plate 111 slows down the airflow speed to prevent the airflow from concentrating too quickly; the uniform air distribution plate 112 evenly distributes the airflow to ensure that the airflow fills the duct smoothly. This optimization design significantly improves the uniformity of the airflow without significantly increasing the air resistance, thereby improving the overall performance and stability of the system.

[0034] In addition, the molecular sieve module 104 is composed of a solid metal mesh frame and a high-performance PDI30 polyurethane foam filter screen, its core function is to efficiently filter water vapor and part of macromolecular substances in the gas. The metal mesh frame not only provides stable structural support for the entire device, but also ensures its durability in high-pressure and high-flow environments. The H3 grade polyurethane foam filter screen can effectively capture water vapor and macromolecular pollutants in the gas due to its excellent pore structure and adsorption performance, preventing them from entering the subsequent module. The filtered water vapor and macromolecular substances are collected through the flow guide channel and finally flow into the sewage sedimentation tank for further treatment.

[0035] Meanwhile, the VOCs treatment module 105 employs four high-voltage electric field devices to generate high-concentration ozone by ionizing oxygen in the air under high-voltage environment. As a strong oxidizing agent, ozone not only has excellent bactericidal, deodorizing, and disinfecting functions, but also can effectively oxidize and decompose the residual organic waste gas and harmful substances in the pre-stage module, converting them into carbon dioxide and water. In the ozone generation unit, the super-oxidizing environment formed can completely eliminate the residual volatile organic compounds (VOCs), carbon monoxide (CO), nitrogen oxides (NOx), hydrogen sulfide (H2S), and various pollutants such as viruses, bacteria, and odors in the flue gas.

[0036] Further, in the pre-stage VOCs treatment module 105, the residual substances in the flue gas are completely eliminated, but at the same time, high-concentration ozone (O3) is also generated. To effectively solve this problem, the ozone reduction module 106 employs aluminum-based ozone reduction plates, which can efficiently reduce the excess O3 generated in the pre-stage treatment process into oxygen (O2) and oxygen ions (O-), thereby ensuring the environmental protection and safety of the flue gas treatment process. This optimization not only improves the treatment efficiency, but also significantly reduces the potential harm of ozone to the environment and equipment.

[0037] Further, to ensure that the total flow rate of the system inlet reaches 6000 m³ / h, and considering a 10% wind pressure loss, the design parameters of the exhaust module 107 outlet should meet the following requirements.

[0038] Structural position Pipe diameter specification m Cross-sectional area m2 Air volume m3 / h Air velocity m / s Air pressure Pa A Φ0.4 0.1256 8000 17.7 195 Further, the fan cabin 109 is connected to the exhaust module 107, and the fan cabin 109 module serves as the core negative pressure system of the flue gas separation and VOCs treatment device, and its performance directly affects the overall operation efficiency of the equipment. The A inlet is connected to the 5.4.7 exhaust module 107 by a DN400 hose. To ensure that the system can efficiently treat smoke and meet strict environmental protection requirements, the negative pressure fan is designed with a maximum air volume of 8000 m³ / H and a maximum air pressure of 7000 Pa, ensuring that a stable negative pressure environment can be provided under various working conditions. In addition, to meet the noise control standard of 60 dBA, the fan cabin 109 adopts 5 cm thick high-quality silent cotton for all-around isolation and noise reduction treatment, effectively reducing the operating noise and improving the comfort of the working environment.

[0039] Finally, the exhaust tank 110 is connected with the fan cabin 109, the exhaust tank 110 is grouped as the last stage processing unit in the smoke and vapor separation and VOCs (volatile organic compounds) processing device, and undertakes the key task of ensuring that the exhaust gas meets the standard. The air inlet is connected with the air outlet of the fan cabin 109 by the D300 silencing pipeline, in the previous stage processing, the flue gas has been processed through multiple processes such as interception, filtration, and ozone chain reduction, and most of the harmful substances have been effectively removed. However, in order to ensure the purity of the exhaust gas and prevent the direct emission of a small amount of untreated gas into the atmosphere, the dispersion tank unit further adopts double protection measures. First, the unit is filled with D high-efficiency activated carbon, which uses its strong adsorption capacity to capture residual VOCs and other harmful gas molecules. Second, an advanced E ion pump system is provided to further decompose and neutralize harmful components in the gas, ensuring that the final exhaust gas meets environmental protection standards.

[0040] When using the multifunctional waste gas treatment device of the embodiment, a large amount of ordinary air is mixed and diluted with the flue gas discharged from the degradation cabin through the flue gas air distribution module 101, and the organic particulate matter in the flue gas is washed and separated by high-pressure spraying and centrifugal devices through the smoke and vapor separation module 103. The remaining carbon dioxide and volatile organic compounds (VOCs) are further separated from water through the molecular sieve module 104, and the volatile organic compounds (VOCs) are decomposed into carbon dioxide and water vapor through the VOCs treatment module 105; the remaining ozone is reduced to ordinary oxygen through the ozone reduction module 106. Finally, a large amount of air and decomposed carbon dioxide are activated and treated by the exhaust tank 110 dispersed by the active ion pump. Therefore, in addition to the diluted carbon dioxide, a large amount of air with active oxygen is still discharged, which can effectively degrade the gasified flue gas and volatile organic compounds through multiple processing modules.
