ONE:Overview
        The regenerative catalytic purification device (RCO) combines the characteristics of RTO and LCO, has the heat storage efficiency of RTO, and also includes the low-temperature catalytic oxidation technology of LCO. This product is developed by the joint efforts of many departments such as technology, production, and electronic control, and absorbs the advantages of similar products. It is another major achievement of the company after RTO and LCO.


TWO:Process flow

THREE:Process principle
In the industrial production process, the discharged organic tail gas enters the rotary valve of the equipment through the induced draft fan, and then the rotary valve completely separates the inlet gas and the outlet gas. The gas first passes through the ceramic material filling layer (bottom layer) and is preheated to generate heat storage and heat exchange, and its temperature almost reaches the temperature set by the catalytic layer (middle layer) for catalytic oxidation. At this time, some of the pollutants are oxidized and decomposed; the exhaust gas continues Through the heating zone (the upper layer, which can be heated by electric heating or natural gas), the temperature is increased and maintained at the set temperature; it then enters the catalytic layer to complete the catalytic oxidation reaction, that is, the reaction generates CO2 and H2O, and releases a large amount of heat to achieve Expected processing effect. The gas after catalytic oxidation enters other ceramic filling layers, and after recovering heat energy, it is discharged into the atmosphere through a rotary valve. The temperature of the exhaust gas after purification is only slightly higher than the temperature before the exhaust gas treatment. The system runs continuously and switches automatically. Through the operation of the rotary valve, all the ceramic filling layers complete the cycle steps of heating, cooling and purification, and the heat can be recovered.

The RCO regenerative catalytic combustion device uses rotary valves to replace many valves and complex hydraulic equipment in traditional equipment. The removal rate of organic matter can reach more than 98%, and the heat recovery rate can reach 95-97%.

◆Regenerative catalytic oxidation technology is a new technology developed on the basis of high temperature incineration (TO) technology and catalytic oxidation (CO). It mainly adopts advanced heat exchange design technology and selection of new animal heat materials. The exchange efficiency of traditional heat exchange design technology is generally 50-70%. Improving heat exchange efficiency means geometrically increasing the manufacturing cost of equipment and greatly increasing the volume of heat exchange equipment; regenerative heat exchange adopts modern advanced technology. The design concept enables the equipment volume and manufacturing cost to be effectively controlled while increasing the heat exchange efficiency to 95% or even higher.
