CO(Catalytic Oxidizer)

CO (Catalytic Oxidizer) is a highly efficient waste gas treatment environmental protection equipment, which combines thermal oxidation (high temperature combustion) and catalytic oxidation (low temperature catalytic reaction) technologies to treat VOCs, CO, odorous gases and other harmful pollutants in industrial waste gas.

Working Principle

The basic working principle of CO is based on catalytic oxidation reaction. The exhaust gas is heated to the temperature required for the catalytic reaction (usually 200℃-400℃) through the preheating system. The treated exhaust gas then enters the catalytic bed, where an oxidation reaction occurs under the action of the catalyst, and the pollutants are decomposed into CO₂ and H₂O. At the same time, the heat released by the reaction is recycled through the heat exchange system.

Product Features

The catalyst participates in the reaction, which can greatly reduce the temperature required for the oxidation reaction, and can recover waste heat to reduce operating costs.

Low temperature and high efficiency
For low-concentration VOCs (1%-10% LEL), the treatment efficiency can reach more than 95%.

High purification efficiency
It can treat a variety of organic substances (benzenes, ketones, esters, etc.) and inorganic gases such as CO and H₂S.

Wide range of applications
It can reduce fuel consumption, reduce secondary pollution such as NOx, and meet the requirements of energy conservation and emission reduction.

Product Operate Guide

Preparation before starting
Startup process
Normal operation
Machine shutdown process

Preparation before starting

1. Check the status of the catalyst
Confirm that there is no blockage, sintering or poisoning (such as S, P deposition).
2. Air tightness test
Check that there is no leakage in the pipes and valves (soap water can be used for detection).
3. Electrical system
The voltage is stable, the grounding is good, and there is no alarm on the PLC panel.
4. Auxiliary equipment
The fan, burner, and heat exchanger are operating normally.
Startup process

1. Turn on the fan
The fan runs at low speed for 5 minutes to purge residual exhaust gas.
2. Start preheating
(1) Electric heating: set the target temperature (such as 300℃) and gradually increase the temperature;
(2) Gas heating: adjust the air-fuel ratio after ignition until stable combustion;
(3) Cut into the catalyst bed: when the preheating zone reaches the set temperature, the exhaust gas is introduced into the catalyst bed.
3. Monitoring parameters
(1) Catalytic bed temperature: maintain at 300℃ - 500℃;
(2) Pressure difference: normal range 500 Pa - 2000 Pa, if it is too high, check whether it is blocked.
Normal operation

1. Automatic mode
PLC automatically adjusts the burner power, air volume, etc. according to the sensor data.
2. Record data
Record temperature, pressure drop, VOCs concentration every hour (if online monitoring is available).
3. Record archive
Save the installation process image, torque record and acceptance report.
Machine shutdown process

1. Cut off the exhaust gas source
Close the air inlet valve and switch to fresh air mode.
2. Cooling stage
Keep the fan running and shut down after the catalyst bed temperature is <100℃.
3. Turn off the power supply/gas source
Disconnect the main power supply and turn the gas valve to the closed position.

FAQs

Reasons for sudden increase in system pressure drop

(1) Blockage of filter or catalyst bed (dust, tar deposition);
(2) Fan failure or air duct obstruction;
(3) High exhaust gas humidity causes catalyst agglomeration.
How to reduce operating energy consumption

(1) Improve heat recovery rate, such as using high-efficiency plate/heat storage heat exchangers.
(2) Reasonably control the preheating temperature to avoid overheating.
(3) Utilize waste heat from exhaust gas, which can be used to preheat fresh air or process water.
Reasons and solutions for the failure of catalyst bed temperature to reach the set value

(1) Exhaust gas concentration is too low and reaction heat release is insufficient. It is recommended to add auxiliary fuel (such as natural gas) to increase the temperature;
(2) Catalyst activity decreases (poisoning or carbon deposition). It is recommended to check the catalyst status and clean or replace it in time;
(3) Insufficient burner power or failure. It is recommended to calibrate the burner to ensure normal air-fuel ratio;
(4) Low heat exchanger efficiency and large heat loss. It is recommended to clean the heat exchanger in time to improve heat recovery efficiency.
