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.

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
