Catalytic Combustion Treatment Equipment

Catalytic combustion treatment equipment: Firstly, it is equipped with a dust removal and flame retardant system. Then it enters the heat exchanger and is sent to the heating chamber to reach the combustion reaction temperature. Through the action of the catalytic bed, the exhaust gas is decomposed into carbon dioxide and water, and then enters the heat exchanger to exchange heat with the low-temperature gas, raising the temperature of the incoming gas to the reaction temperature. If the reaction temperature cannot be reached, the heating system department compensates for heating through an automatic control system. Using catalysts as intermediates to transform gases into stable water and carbon dioxide gases at lower temperatures.

① Easy to operate, with automatic control achieved during device operation.

② The device starts up and only takes 15-30 minutes to heat up to the ignition temperature, with low energy consumption.

③ Adopting the excellent precious metal palladium platinum impregnated honeycomb carrier catalyst today, it has a large specific surface area, low resistance, and good purification rate.

④ Waste heat can be returned to the drying oven, reducing the power consumption in the original drying oven; It can also be used as a heat source for other purposes.

⑤ Long service life, catalysts are usually replaced every two years, and the carrier can be produced.

The catalytic combustion treatment equipment mainly consists of heat exchangers, combustion chambers, catalytic reactors, heat recovery systems, and exhaust chimneys for purifying flue gas. Its purification principle is that before entering the combustion chamber, the unpurified gas is preheated by the heat exchanger and sent to the combustion chamber, where it reaches the required reaction temperature. The oxidation reaction takes place in the catalytic reactor, and the purified flue gas releases some heat through the heat exchanger before being discharged into the atmosphere through the chimney.

The catalytic combustion treatment equipment sets the desorption time according to the different exhaust gas content and daily working hours. Generally, detachment takes 15-20 days. The detachment time is 3-5 hours. The desorption time of catalytic combustion equipment is mainly determined by the filling amount of activated carbon and the adsorption value of activated carbon. The filling amount of activated carbon is high, and the adsorption value is high. The desorption time interval of catalytic combustion equipment is relatively long, usually 15-20 days for desorption. If the activated carbon selected for catalytic combustion equipment has a low adsorption value and a small filling amount of activated carbon in the equipment, the catalytic combustion equipment is easily saturated. The typical desorption time for catalytic combustion devices like this is once every 3-5 days, which greatly wastes electricity. Increased usage costs, and the short service life of activated carbon. Good activated carbon is usually replaced every 2-3 years, while activated carbon for catalytic combustion equipment that requires frequent desorption needs to be replaced every year.
