China Honeycomb Ceramic Heat Accumulator as Ceramic Catalyst for Rto Rco

Honeycomb Ceramic heat accumulator as ceramic catalyst for RTO & RCO
Description:
Honeycomb ceramic heat accumulator is new developed porous industrial ceramic, as a storage material of regenerative thermal oxidation and catalytic oxidation (RTO,RCO) equipment for volatile organic compounds (VOCs) and hazardous air pollutant (HAPS) converted into carbon dioxide and water vapor through thermal oxidation.
Appearance:
Material: alumina porcelain,Mullite, cordierite ,stoneware porcelain etc.
Application:
1)Regenerative thermal oxidizer(RTO) is effective exhaust air treatment for a wide range of processes, the system uses a bed of ceramic material to absorb heat from the exhaust gas and use the captured heat to preheat the incoming process gas stream.the RTO converts volatile organic compounds(VOCs) and hazardous air pollutants(HAPs) to carbon dioxide and water vapor through thermal oxidation.
2).Regenerative catalytic oxider(RCO) is improvded on basis of RTO structure, added in the oxidizers bolier with the layer of special catalyst material,Using catalytic oxidation to provide sufficient heat required to destroy VoC, this technology can reduce the RTO system operating temperatures,improve efficiency and reduce the flue consumption;RCO destroys air toxins and volatile organic compounds (VoCs),that are discharged in industrial process exhausts,The RCO system achieves VOC destruction through the process of catalytic oxidation,converting the VOCS to carbon dioxide and water vapor, recycling released energy to reduce operation costs;Honeycomb thermal store catalyst ceramic is used for waste gas treatment(RTO/RCO) of different requirements, selecting many kinds of new highly effective ceramic material to make.It has the properties of corrosion resistances,high specific surface area,low resistance,low thermal expansion coefficient,good thermal conductivity and thermal-shock resistance performance.
