RCO(Regenerative Catalytic Oxidizer)

RCO (Regenerative Catalytic Oxidizer) is a highly efficient organic waste gas treatment equipment, mainly used for the treatment of medium and low concentration VOCs. RCO combines RTO and CO technology to oxidize and decompose organic matter in the waste gas through catalytic oxidation, and uses heat storage to recover heat, achieving efficient and energy-saving waste gas treatment.

Working Principle

The core principle of RTO is catalytic oxidation and heat storage recovery. In the combustion chamber, VOCs in the exhaust gas are oxidized and decomposed into CO2 and H2O under the action of the catalyst, while releasing a large amount of heat.The high-temperature gas generated by oxidation flows through the heat storage body, heating the heat storage body and storing heat for subsequent preheating.
By switching valves or rotating valves, the air flow direction is changed, so that the heat storage body alternately stores and releases heat, achieving continuous operation.

Product Features

Treatment efficiency ≥ 95%, suitable for medium and low concentration (100-2000mg/m³) and large air volume waste gas treatment.

High-efficiency purification
Using the waste gas's own heat to maintain the reaction, it saves 30%-50% more energy than direct combustion, reducing energy consumption and greenhouse gas emissions.

Energy saving and environmental protection
Under the action of the catalyst, the catalytic oxidation temperature is reduced by about 50% compared with rto, and the heat recovery efficiency of the heat storage body is ≥ 95%, which significantly reduces fuel consumption and operating costs.

High thermal efficiency
It can treat vocs and odorous gases such as alkanes, aromatics, ketones, and esters.

Product Operate Guide

Pre-inspection
Cold start preheating
Normal shutdown of the machine
Emergency shutdown

Pre-inspection

1. Confirm that the power supply and gas source (such as natural gas, compressed air) are normal;
2. Check whether the heat storage ceramic body and catalyst are intact, without blockage or damage;
3. Confirm that the valve (switching valve, bypass valve) is flexible and well sealed;
4. Confirm that there is no leakage in the pipeline and the fan and motor are lubricated normally;
5. Pre-treat the exhaust gas to ensure that there is no dust, oil mist, high concentration of S/Cl and other substances that are easy to cause catalyst poisoning in the exhaust gas. If the exhaust gas concentration exceeds 5% LEL (lower explosion limit), it needs to be diluted or LEL monitoring interlock is used.
Cold start preheating

1. Turn on the main fan and purge the system with low air volume (30%-50%) for 10 minutes;
2. Start the burner or electric heater to raise the temperature of the catalytic reaction chamber to 250℃-300℃ (the specific temperature depends on the catalyst model);
3. The preheating time is usually 1-2 hours, and enter the operation mode after the temperature stabilizes;
4. Switch the operation mode
(1) Switch the control system to automatic mode, and the heat storage chamber switching valve starts to work periodically (the cycle is usually 5-10 minutes);
(2) Slowly increase the exhaust gas intake to the designed air volume, and monitor the pressure difference and temperature fluctuations.
Normal shutdown of the machine

1. Gradually reduce the exhaust gas intake, turn off the burner, and switch to cooling mode;
2. The fan continues to run for 1-2 hours and shuts down after the catalyst bed temperature drops to <150℃;
3. Cut off the power supply and gas source, and fill in the shutdown record.
Emergency shutdown

1. Trigger conditions: fire, explosion risk, serious equipment leakage;
2. Immediately press the emergency stop button, close the air inlet valve, and open the emergency drain valve.

FAQs

Reasones of valve jam or leakage

(1) Valve deformation due to high temperature or aging of seals. It is recommended to manually clean the valve body and replace the high temperature resistant seal ring after shutdown;
(2) Dust accumulation causes track jam. It is recommended to lubricate the valve guide rail regularly (weekly)
Ceramic heat storage body cracking after shutdown

(1) Rapid cooling and heating cause thermal shock cracking of the heat storage body. Please shut down strictly according to the regulations to avoid forced cooling;
(2) Unqualified material (poor thermal shock resistance). High-quality heat storage body (such as cordierite material) can be replaced
Abnormally increased pressure difference

(1) Heat storage body blockage (dust, sticky organic matter adhesion). It is recommended to use compressed air to blow back the heat storage body after shutdown. In severe cases, chemical cleaning can be used;
(2) Filter failure (pre-dust removal is not thorough). It is recommended to replace or upgrade the pre-treatment filter (such as adding bag dust removal)
