RTOCompared to traditional catalytic combustion and direct combustion thermal oxidation furnaces（TO）Compared to others, it has high thermal efficiency（≥95%）It has the characteristics of low operating costs and the ability to handle high air volume and low concentration waste gas. When the concentration is slightly higher, secondary waste heat recovery can also be carried out, greatly reducing production and operating costs.

RTO (Regenerative Thermal Oxidizer,abbreviationRTO),Regenerative oxidation furnace. The principle is to remove organic compounds from the exhaust gas at high temperatures（VOCs)Oxidation into corresponding carbon dioxide and water, thereby purifying exhaust gas and recovering the heat released during the decomposition of exhaust gas, three chamberRTOThe efficiency of exhaust gas decomposition has reached99%Above, the heat recovery efficiency has reached95%above.RTOThe main structure consists of a combustion chamber, a heat storage chamber, and a switching valve. According to the actual needs of customers, choose different heat recovery methods and switching valve methods.

Working principle

The principle is to heat the organic waste gas to760Above Celsius (depending on the composition), the exhaust gasVOCDecompose into carbon dioxide and water through oxidation. The high-temperature gas generated by oxidation flows through a specially designed ceramic thermal storage body, causing the ceramic body to heat up“thermal storage”This“thermal storage”Used to preheat the organic waste gas that enters later. Thus saving fuel consumption for exhaust gas heating. Ceramic heat storage chambers should be divided into two or more, with each chamber undergoing heat storage in sequence-exothermic-The cleaning and other procedures are repeated and work continuously. Heat storage chamber“exothermic”Immediately introduce an appropriate amount of clean air to clean the heat storage room (to ensureVOCThe removal rate is98%Only after the cleaning is completed can one enter“thermal storage”Program. Otherwise, there will be residualVOCSDischarging smoke into the chimney reduces treatment efficiency.

Applicable exhaust gas

●Types of organic waste gases used: hydrocarbons, olefins, alcohols, ketones, ethers, esters, aromatic hydrocarbons, benzene and other hydrocarbon organic waste gases.

●Low concentration of organic matter(Simultaneously meet the requirement of being below25%LFL)High air volume

●The exhaust gas contains multiple organic components, or the organic components often change

●Waste gas containing components that can easily cause catalyst poisoning or activity degradation

Performance characteristics

advantage:
