Product Introduction of Catalytic Combustion Equipment for Waste Gas Treatment in Plastics Factories

The gas-solid phase catalytic reaction generated by catalytic combustion equipment for waste gas treatment is essentially a deep oxidation process involving active oxygen. 

During catalytic combustion, the catalyst lowers the activation energy, and its surface adsorption properties enrich reactants. 

With the help of the catalyst, the waste gas undergoes flameless combustion at a lower ignition temperature, oxidizing and decomposing into CO2 and H2O, releasing a large amount of heat energy, 

thereby achieving the purpose of removing harmful substances from the waste gas. Our company's waste gas purification catalytic combustion equipment, under the action of a catalyst, rapidly oxidizes hydrocarbons in organic waste gas into water and carbon dioxide at a lower temperature, achieving the treatment purpose. 

The catalytic combustion process takes place in a catalytic combustion device. Organic waste gas is first preheated to 200-400℃ through a heat exchanger before entering the combustion chamber. When passing through the catalyst bed, hydrocarbon molecules and oxygen molecules in the mixed gas are adsorbed onto the catalyst surface and activated. 

Because surface adsorption lowers the activation energy of the reaction, hydrocarbons and oxygen molecules rapidly oxidize at a lower temperature, producing carbon dioxide and water.

Technical Parameters

The gas-solid phase catalytic reaction in catalytic combustion equipment is essentially a deep oxidation process involving active oxygen. 

During catalytic combustion, the catalyst lowers the activation energy, and its surface adsorption properties enrich reactants. With the help of the catalyst, the exhaust gas is able to ignite at a relatively low temperature.

Performance Characteristics

The complete unit consists of a dry filter, activated carbon adsorption/desorption tower, catalytic combustion chamber, flame retardant, related fans, valves, and an electrical control system.

The gas after catalytic oxidation enters other ceramic packing layers. After recovering heat energy, it is discharged into the atmosphere through a rotary valve. The purified exhaust temperature is only slightly higher than the temperature before waste gas treatment. 

The system operates continuously and switches automatically. Through the operation of the rotary valve, all ceramic packing layers complete the heating, cooling, and purification cycle, thus recovering heat.

The RCO regenerative catalytic combustion unit uses rotary valves to replace numerous valves and complex hydraulic equipment in traditional equipment. The organic matter removal rate can reach over 98%, and the heat recovery rate reaches 95-97%.

Working Principle: 

In industrial production, the emitted organic waste gas enters the equipment's rotary valve via an induced draft fan. 

The rotary valve completely separates the inlet and outlet gases. The gas first passes through a ceramic material filling layer (bottom layer) for preheating, where heat is stored and exchanged, 

reaching a temperature almost at the set temperature for catalytic oxidation in the catalytic layer (middle layer). At this point, some pollutants are oxidized and decomposed. 

The waste gas continues to pass through the heating zone (upper layer, which can be heated electrically or by natural gas) for further heating and maintenance at the set temperature. 

It then enters the catalytic layer to complete the catalytic oxidation reaction, producing CO2 and H2O and releasing a large amount of heat to achieve the desired treatment effect.

Application Areas

This device can adsorb and purify waste gases containing organic solvents such as benzene, alcohols, ketones, esters, and gasoline. 

It is particularly suitable for working environments with low-concentration, high-volume emissions or high-concentration, intermittent emissions. 

It effectively purifies the environment, eliminates pollution, improves the working environment, ensures worker health, and achieves emission standards. 

Therefore, it can be used for the purification of harmful organic waste gases and the elimination of odors generated in industries such as chemical, light industry, coating, 

electronics, electromechanical, printing, home appliances, shoemaking, batteries, plastics, films, rubber, coatings, pharmaceuticals, furniture, shipbuilding, automobiles, and petroleum.
