Regenerative catalytic oxidation (RCO) technology
Regenerative catalytic oxidation unit( Regenerative Catalytic Oxidizer),Combined with regenerative thermal oxidation and catalytic oxidation, this technology can reduce the temperature of RTO system, effectively improve the destruction efficiency and reduce the consumption of fuel.RCO system is based on the structure of RTO, adding a layer of special catalyst material in the oxidation furnace, using the catalyst oxidation to provide enough heat to destroy VOCs, in order to reduce the operating temperature of RTO system and improve the rate of oxidation reaction.Different from thermal combustion, RTO is flameless combustion, which can automatically shut off the heater when the inlet exhaust gas is treated above 300 ℃. It is widely used because of its environmental friendliness, high efficiency and energy saving.
RCO Technological principle
Before the furnace body carries out waste gas treatment, the heating chamber and the heat storage bed are preheated;After preheating, connect the waste gas source to the equipment.Under the catalysis of the auxiliary fan, the heat exchange of the organic waste gas is carried out by the preheated ceramic body A at first. the waste gas enters the heating zone after the first heat raising rotation, and the waste gas gets the second heat raising in the heating zone. at this time, the waste gas temperature reaches the temperature requirement of the reaction with the catalyst and enters the catalytic chamber to carry out the reaction to produce CO2 and H2O and release the heat energy.讯飞随声译:
The treated clean gas is then recharged by the ceramic regenerator B and discharged by the fan.When the temperature of the inlet temperature measuring rod of the exhaust fan reaches the set temperature, the valve is switched from the heat storage ceramic B to the exhaust gas precession to heat transfer, and from the ceramic heat storage body A to discharge, and so on.
