Regenerative Thermal Oxidizer (RTO) technology is an important solution in the field of industrial waste gas treatment, which treats harmful components in organic waste gas through high-temperature oxidation and harmless treatment. RTO is an efficient equipment for treating organic waste gas (VOCs). It decomposes organic waste gas through thermal oxidation and recovers waste heat in the process, thereby achieving the goal of purifying waste gas. The RTO system uses specially designed thermal storage ceramic fillers to alternately store and release thermal energy, in order to maintain efficient high-temperature oxidation processes. This process not only significantly improves heat utilization efficiency and reduces operating costs, but also achieves a good balance between environmental protection and economic benefits.
The working principle of RTO thermal storage incinerator is mainly based on the synergistic effect of exhaust gas switching valve and multiple thermal storage chambers. At the beginning of the process, the organic waste gas first enters a heat storage chamber, and the high temperature comes from the heat recovery of the previous cycle. Subsequently, the exhaust gas is rapidly heated to above 750 ℃, and the organic pollutants within it are rapidly oxidized into carbon dioxide and water vapor at such high temperatures. After processing, the high-temperature gas flows into another heat storage chamber, releasing heat to heat the ceramic packing and provide necessary thermal energy for the subsequent pre-treatment of exhaust gas. At the same time, the previously preheated heat storage chamber is switched to the cooling state by switching the valve, starting a new cycle.
The main advantages of RTO thermal storage incinerator include efficient thermal energy utilization rate (≥ 95%), reliable operation, and the ability to treat high air volume and low concentration exhaust gas. Compared with traditional high-temperature direct incineration and catalytic combustion processes, RTO has higher thermal efficiency and better environmental adaptability. RTO is suitable for organic waste gases with high concentrations, organic waste gases with large processing capacities in the coating and pharmaceutical industries, as well as organic waste gases containing triphenyls, phenols, aldehydes, ketones, ethers, esters, and other organic components in industrial electrical, chemical, plastic, shoe making, printing, tin can printing, and power cable production industries.
In the application of RTO thermal storage incinerators, it is not only necessary to consider the improvement of thermal efficiency, but also to ensure the stability and reliability of operation. The manufacturer of the Santy Company waste gas treatment equipment has adopted advanced VOCs waste gas treatment technology in the design and manufacturing process, improving VOCs purification efficiency and enabling it to effectively respond to more complex waste gas treatment needs.
