Principle Introduction:
Under the action of the catalyst, organic matter is oxidized and decomposed into carbon dioxide and water at relatively low temperatures (280-320 ℃) through the active components of the catalyst, forming flameless combustion.
Usually, complete oxidation of VOCs (direct combustion or thermal combustion) requires higher temperatures and longer residence times. Taking benzene as an example, without a catalyst, to achieve complete oxidation, the temperature needs to be above 800 ℃ and the residence time should be at least 1-2 seconds. With the participation of a catalyst, the complete oxidation temperature and residence time significantly decrease, only requiring 250-400 ℃ and 0.1-0.2 seconds, fully demonstrating the superiority of catalytic combustion method.
Advantages of VOCs treatment equipment system:
1.Low operating costs, no need to consume a large amount of electricity or gas, saving operating costs;
2.Not producing secondary pollutants such as nitrogen oxides (NOx);
3.Low investment; Fully automatic control, ready to use immediately; Resistant to impact loads, not easily affected by changes in pollutant concentration and temperature;
4.Efficient heat recovery rate, CO heat recovery efficiency ≥ 65%;
5.High safety and purification efficiency of over 98%;
Scope of application:
1.Suitable for industries such as electronics, spray painting, printing and dyeing, fine chemicals, printing, petrochemicals, machinery, building materials, metallurgy, etc.
2.Widely applicable, especially suitable for treating large volume, medium high concentration exhaust gases. For multi-component, non recyclable exhaust gases, catalytic oxidation method has better treatment effect.
