Technology brief

Regenerative Catalytic Oxidizer (RCO) is an organic waste gas treatment equipment which combines low temperature catalytic oxidation with thermal storage technology. The equipment is a new type of volatile organic compounds processing equipment developed on the basis of RTO technology.

Technological principle

Organic waste gas was heated through ceramic filled layer, and the temperature almost reached the set temperature of catalytic oxidation. Some of the organic waste gas was oxidized and decomposed. The exhaust gas continued to rise through the electric heating zone and maintained at the set temperature. After entering the catalytic layer, the catalytic oxidation reaction at lower temperature (250 C -300 C) generated CO. Two And H Two O, and release a lot of heat to achieve the desired effect. After catalytic oxidation, gas enters other ceramic filled layers, and heat is released to the atmosphere. After purification, the exhaust temperature is only slightly higher than that before the exhaust gas treatment. The system operates continuously and automatically switches. Through the rotary valve operation, all ceramic filling layers are completed by heating, cooling and purifying cycle steps, and heat is recovered.
