A strong “cocktail” of emissions -
separating emission mixtures economically
Kappa has developed a hybrid filter system for industrial dedusting and simultaneous separation of gases and odors. The system separates both coarse and fine dusts as well as a wide range of gaseous and odorous emissions. This ensures employee protection, compliance with environmental regulations and the protection of local residents.
Some industrial processes release a whole “emission cocktail” of different airborne emissions - coarse dusts, fine dusts, smoke, amines, odors or VOCs. The dust loads are generally controlled with conventional systems. There is a lack of solutions for the separation of gaseous and odor-intensive emissions that are also economically viable. Kappa has therefore dealt intensively with this challenge and developed a hybrid solution. It is suitable for both small and large systems.
The basis of surface filtration
The Kappa dedusting systems form the heart of the hybrid exhaust air purification system Kappa Ekon®, Mykron®, Plenon® or Zeron®. All these systems are based on surface filtration, in which the dust loads are retained on the surface of the filter element without penetrating the material. The filter materials have a fine-pored surface with incorporated micro- and/or nanofibers.
In order to treat the mixture of coarse and fine dust as well as gaseous substances in one system, an exhaust air purification system is installed upstream of the Kappa dedusting technology: The Kappa AdcoatTM. It ensures that the exact amount of reactant (additive) required for the process parameters is fed into the extraction system. The additive reacts chemically and physically with the emissions and binds gaseous substances and odours. The reaction begins as soon as the additive is injected into the pipework (entrained flow sorption).
The additive then covers the large surface of the filter elements with a defined reaction layer. This immediately forms a stable reaction bed in which the gaseous emissions are separated according to the fixed bed adsorption principle. This also prevents condensation products with sticky or resinous properties from reaching the filter surface directly and blocking it. Dust and gaseous emissions are thus separated efficiently and effectively on the filter material surface at the same time. The mixture of additive and emissions on the filter material surface is automatically discharged as required.
