Regenerative Thermal Oxidizer (RTO)RTO performance characteristics:※ Energy saving※ Heat recovery exceeds 97%※ VOC removal efficiency** is 99%※ High air volume & VOC inlet concentration up to 25% LEL※ Reliable valve design guarantees VOC removal rate of 99%※ Can design and produce multi-tower RTO system※ User-friendly design, quick installation and easy maintenance※ PLC control system※ Inverter reduces power consumption※ Integrated VPN can be used for remote fault diagnosis and get real-time operation※ Very little NOx generationHow RTO works:The residual heat of the exhaust gas is transferred to the ceramic regenerator and then transferred to the inlet gas again. In this way, the inlet air and VOCs can be heated to a fully oxidized temperature with relatively little energy loss. The specific process is: the organic exhaust gas is directly heated to a high temperature above 800 °C, oxidative decomposition. The high-temperature gas generated after oxidation passes through the ceramic heat storage portion, and since the ceramic has good heat storage property, the furnace chamber is always maintained at a high operating temperature, and the fuel consumption for preheating and heating of the exhaust gas is saved. The ceramic heat storage portion consists of two or more chambers, and the relatively clean gas after pyrolysis needs to be purged from each chamber before entering the exhaust gas treatment system or directly discharged to ensure the VOC removal rate.1.

活性炭吸附性能: ※ 管道布局準確,結構緊湊;※ PLC自動化控制;※ 采取多重安全設施;※ 運行穩定,維護簡便,運行費用較低。活性炭吸附裝置采用優質產品,吸附材料為活性炭,結構類似晶體狀,分子像搭架子似連在一起,中間形成很多空腔,這便形成了很多微孔,具有很強的吸附能力,對吸附質分子的吸附能力遠超其他類型的吸附劑。活性炭是一種主要由含碳材料制成的外觀呈黑色,內部孔隙結構發達、比表面積大、吸附能力強的一類微晶質碳素材料。活性炭材料中有大量肉眼看不見的微孔,1克活性炭材料中微孔,將其展開后表面積可高達800-1500平方米,特殊用途的更高。也就是說,在一個米粒大小的活性炭顆粒中,微孔的內表面積可能相當于一個客廳面積的大小。正是這些高度發達,如人體毛細血管般的孔隙結構,使活性炭擁有了優良的吸附性能。分子之間相互吸附的作用力也叫“凡德瓦引力”。雖然分子運動速度受溫度和材質等原因的影響,但它在微環境下始終是不停運動的。由于分子之間擁有相互吸引的作用力,當一個分子被活性炭內孔捕捉進入到活性炭內孔隙中后,由于分子之間相互吸引的原因,會導致更多的分子不斷被吸引,直到添滿活性炭內孔隙為止。       蜂窩狀活性炭,具有很多微孔及很大的比表面積,依靠分子引力和毛細管作用,能使溶劑蒸汽和揮發性物質吸附于其表面,又根據不同物質的物理和化學性質,利用高溫將其脫附出來;工作原理:含有機物的廢氣經風機的作用,經過活性炭吸附層,有機物質被活性炭特有的作用力截留在其內部,潔凈氣體排出;經過長時間吸附后,活性炭達到飽和狀態時,停止吸附,此時有機物已被濃縮在活性炭內;此時應定期更換活性炭以確保處理效率穩定。活性炭吸附法不需要添加任何的絮凝劑和氧化劑等化學試劑,直接利用活性炭的微孔結構進行吸附;成本低,操作簡單;活性炭所用的原料是果殼、煤和木材等物質,相對來講,成本較低。且進行吸附時,沒有太高的技術要求,操作簡單靈活。活性炭吸附法在高溫環境下,吸收有害氣體,會釋放,鎖不住;另外活性炭需要定時更換處理。小型活性炭吸附塔技術性能及特點: A、該設備設計原理先進,用材獨特,性能穩定,操作簡單,安全可靠,無二次污染。設備占地面                積小、重量較輕。吸附床采用類似抽屜形式結構,裝填方便,更換容易。 B、采用新型的活性炭吸附材料——蜂窩狀活性炭,其與粒(棒)狀相比具有優勢的熱力學性能,              低阻低耗,高吸附率等,極適合于大風量下使用。工藝流程圖:

Low temperature plasma decompositionLow-temperature plasma technology, also known as non-equilibrium plasma technology, generates a large number of high-energy particles through dielectric discharge under the action of an applied electric field. High-energy particles and organic pollutant molecules undergo a series of complex plasma physical and chemical reactions, thus organic The pollutants are degraded into non-toxic and harmless substances.The low temperature plasma is the fourth state of the substance after the solid state, the liquid state, and the gaseous state. When the applied voltage reaches the discharge voltage of the gas, the gas molecules are broken down to produce a mixture including electrons, various ions, atoms and radicals. . Although the electron temperature is high during discharge, the temperature of the heavy particles is very low, and the whole system exhibits a low temperature state, so it is called a low temperature plasma. Low-temperature plasma degradation of pollutants is the use of these high-energy electrons, free radicals and other active particles and pollutants in the exhaust gas, so that the pollutant molecules decompose in a very short time, and subsequent various reactions to achieve degradation of pollutants the goal of.During the plasma chemical reaction process, the energy transfer during the reaction of the plasma transfer chemical energy is as follows:(1) Electric field + electron → high energy electron(2) High energy electrons + molecules (or atoms) → (excited atoms, excited groups, free groups) Reactive groups(3) Reactive group + molecule (atomic) → product + heat(4) Reactive group + reactive group → product + heatLow temperature plasma technology for treating organic waste gas has the following advantages:1 low energy consumption, can react with the catalyst at room temperature, without heating, greatly saving energy;2 Convenient to use, can be adjusted according to air volume changes and site conditions during design;3 does not produce by-products, the catalyst can selectively degrade by-products generated in the plasma reaction;weakness is:1 is sensitive to water vapor, when the water vapor content is higher than 5%, the treatment efficiency and effect will be affected;2 It is sensitive to dust-containing gas, and the treatment efficiency is obviously reduced.

UV photocatalytic oxidation decomposition technologyHigh-energy UV/ozone photolysis technology is a new type of exhaust gas treatment technology.The basic principle is: on the one hand, under the irradiation of high-energy ultraviolet rays, various chemical reactions such as ring-opening and fracture of volatile organic compounds and other pollutants (VOCs) are generated, and the degradation is converted into low-molecular compounds such as CO2 and H2O; On the one hand, the high-energy ultraviolet light is used to decompose the oxygen in the air to generate ozone, and the ozone absorbs ultraviolet rays to generate oxygen radicals and oxygen. The oxygen radicals react with water vapor in the air to form hydroxyl radicals, a stronger oxidant, and Organic waste gases such as alcohols, aldehydes, and carboxylic acids are completely oxidized into inorganic substances such as water and carbon dioxide. In addition, ozone that does not absorb ultraviolet rays is also a strong oxidizing agent. When it is contacted with some organic waste, it is oxidized to form inorganic substances such as water and carbon dioxide, and has an immediate deodorizing effect. It adopts nickel-based photocatalyst plate, which has the characteristics of corrosion resistance, large specific surface area, light weight, small pressure loss, good adhesion and easy to fall off, and high purification efficiency.The molecular bonds of high-molecular-contaminated substances are converted into low-molecular harmless or low-harm substances such as H2O and CO2 through the cracking of high-energy ultraviolet light energy and the oxidative polymerization of ozone.Molecular formula of ozoneUVD→O2 = O ̄+O+ = O2 +O ̄; O2+ O+→O3The process of cracking and transformation of pollutant molecules isUVD→H2S = H+ + H ̄+S→H + O3S +O3 →H2O+ SO42-UVD→CS2= C+ O3; S ̄+ S +'+ O3→CO2+ SO42-                                    UV photocatalytic internal structure diagram                                     UV photocatalytic appearance
