The honeycomb ceramic heat regenerator of RTO incinerator has the characteristics of high load softening temperature, small expansion coefficient, strong resistance to quenching and quenching, and long service life. The basic principle of RTO incinerator is to oxidize organic waste gas to generate CO2 and H2O at high temperature (>760), and the use of honeycomb ceramic heat regenerator can maximize the reuse of heat energy, and the heat rate is greater than 95. The geometric characteristics of RTO honeycomb ceramic regenerator are generally made into columnar regenerators with sizes of 150mm, 150mm 150mm and 150mm 150mm 300mm, and are built in the RTO regenerator. The number of holes in a section through which the air flows through a packer, known as the pore density (also expressed as the number of holes per square inch CSI), typically ranges from 13 13 (169 holes) to 60 60 (3600 holes).
The higher the pore density, the larger the surface area per unit volume, which provides a larger heat transfer area and thus improves heat transfer efficiency. The organic exhaust gas is heated to more than 760, so that the VOC in the exhaust gas is oxidized and decomposed into carbon dioxide and water. The high-temperature gas produced by oxidation flows through a special ceramic heat storage body, which heats up the ceramic body and "stores heat", which is used to preheat the organic waste gas that enters later. This saves fuel consumption for exhaust gas heating.
The RTO incinerator honeycomb ceramic heat storage body should be divided into two or more areas or chambers, and each heat storage chamber should go through the procedures of heat storage-exothermy-cleaning in turn, and work continuously over and over again. After the regenerator is "exothermic", part of the clean exhaust gas that has been treated and qualified should be introduced immediately to clean the regenerator (to ensure that the VOC removal rate is more than 95%), and only after the cleaning is completed can it enter the "heat storage" procedure.
Honeycomb ceramic heat regenerator is the key material of regenerative industrial kiln, and it is the heat exchange medium of regenerative industrial kiln. The honeycomb ceramic heat accumulator absorbs the heat of the exhaust flue gas in the industrial kiln and stores it, and then heats the air and fuel with the stored heat, which not only improves the calorific value of the fuel, reduces the emission temperature of the exhaust gas, saves energy, but also reduces the emission of CO2 and NOx, which is conducive to environmental protection. The cross-sectional holes of honeycomb ceramic heat storage mainly include square, hexagonal and circular three-hole structures, and the channels are parallel to each other straight channel structure, which greatly reduces the resistance of the stomata flow through and greatly improves the single-hole volume heat exchange efficiency of the honeycomb ceramic heat storage body.
The main materials of the honeycomb ceramic heat storage body of the RTO incinerator: dense cordierite, high alumina, corundum, mullite, chromium corundum, zirconia corundum, silicon carbide, etc.
