catalytic combustion

The catalytic purification device is equipped with a heating chamber. Start the heating device to enter the internal circulation. When the heat source reaches the boiling point of the organic matter, the organic matter escapes from the activated carbon and enters the catalytic chamber for catalytic decomposition into CO₂ and H₂O, while releasing energy. When using the released energy to enter the desorption of the adsorption bed, the heating device completely stops working. The organic waste gas self-ignites in the catalytic combustion chamber, and the tail gas is regenerated, and the cycle continues until the organic matter is completely separated from the activated carbon and decomposed in the catalytic chamber. The activated carbon is regenerated, and the organic matter is catalytically decomposed; for the batch type, the heating device needs to be started for each desorption, and the heating power is not required for continuous desorption.

Catalytic combustion: Use a catalyst as an intermediate to convert organic gases into harmless water and carbon dioxide at a lower temperature, that is: send the organic gases desorbed from saturated activated carbon into the purification device through the action of the desorption induced draft fan (the organic solvent desorbed from activated carbon is in gaseous state). First pass through the dust removal and fire arrester system, then enter the heat exchanger, then send it to the heating chamber. Through the heating device, the gas reaches the combustion reaction temperature, and then through the action of the catalytic bed, the organic gases are decomposed into carbon dioxide and water, and then enter the heat exchanger to exchange heat with the low-temperature gas, so that the temperature of the incoming gas rises to the reaction temperature. If the reaction temperature is not reached, the heating system can realize compensatory heating through the automatic control system to make it burn completely, which saves energy. The effective removal rate of waste gas reaches the standard for discharge, which meets national emission standards; the purification efficiency of catalysis is above 97%.

This device is composed of the main unit, induced draft fan and electric control cabinet. The main unit of the purification device is composed of a heat exchanger, catalytic bed, electric heating elements, fire and dust arrester, explosion-proof device and so on. The fire and dust arrester is located on the air inlet pipe, and the explosion-proof device is installed on the top of the main unit.

Equipment characteristics

1. Use precious metals palladium and platinum plated on honeycomb ceramic carriers as catalysts, with high purification efficiency, long catalyst service life, smooth air flow and low resistance.

2. Complete safety facilities: equipped with fire and dust arresters, pressure relief ports, over-temperature alarms and other protective facilities.

3. Power consumption: Preheat for 15 to 30 minutes with full power heating when starting to work, and only consume fan power during normal operation. When the waste gas concentration is low, automatic intermittent compensatory heating is performed.

Advantages of the device

1. This equipment has advanced design principles, unique materials, stable performance, simple operation, safe and reliable, and no secondary pollution. The equipment covers a small area and is light in weight. The adsorption bed adopts a drawer-type structure, which is convenient for loading and easy to replace.

2. Adopt new activated carbon adsorption material - honeycomb activated carbon. Compared with granular (rod-shaped) activated carbon, it has superior thermodynamic properties, low resistance and low consumption, high adsorption rate and other advantages, and is very suitable for use under large air volume.

3. The catalytic combustion chamber uses precious metal catalysts on ceramic honeycombs, with low resistance. It can operate normally with a low-pressure fan, which not only consumes less power but also has low noise.

4. The air volume of the catalytic combustion device is one-tenth of the waste gas source air volume (referring to the catalytic purification device as the desorption and heating air volume, which is about 1/10 of the air volume of each activated carbon adsorption box. Currently, the treatment air volume of each activated carbon box is 10000m³/h, and the selected catalytic air volume is 2000m³/h. At the same time, the heating power maintenance time is about 1 hour, which saves energy.

5. The activated carbon bed that adsorbs organic waste gas can use the heat generated by catalytic combustion of waste gas for desorption and regeneration. The desorbed gas is sent to the catalytic combustion chamber for purification, no additional energy is required, the operating cost is low, and the energy-saving effect is good.
