A strong "cocktail" of emissions – the economic separation of emission mixtures

 

Kappa has developed a hybrid filter system for industrial de-dusting and the simultaneous separation of gases and odours. Both coarse and fine dust - as well as a wide variety of gaseous and odour-intensive emissions - are separated within the system. The protection of employees, compliance with environmental regulations and the protection of residents are thus achieved.

Some industrial processes release a whole "emission cocktail" of different, airborne emissions - coarse dust, fine dusts, smoke, amines, odours and VOCs. The dust loads are usually controlled by means of standard systems. For the separation of gaseous and odour-intensive emissions, economically justifiable solutions are often missing. Kappa has therefore dealt intensively with this challenge and developed a hybrid solution. It is suited to both small and large plants.

 

The basis of surface filtration

At the heart of the hybrid exhaust air purification system lies one of Kappa's de-dusting systems, such as the Kappa Ekon®, Mykron®, Plenon® or Zeron®. All of these systems are based on surface filtration, which means dust loads are retained on the filter element surface without penetrating the material. The filter materials have a fine-pored surface with micro- and/or nano-fibres incorporated into them.

In order to treat the mixture of coarse and fine dusts and gaseous substances within a single system, Kappa de-dusting technology is preceded by an exhaust air cleaning system: the Kappa AdcoatTM. It ensures that the amount of reactant (additive) fed into the suction system is precisely the amount required according to the process parameters. The additive chemically and physically reacts with the emissions, binding on to gaseous substances and odours. The reaction starts immediately at the point of injection of the additive into the piping (air flow adsorption).

The additive then covers the large surface of the filter elements with a defined reaction layer. This immediately forms a stable reaction bed. Gaseous emissions are deposited into this according to the fixed bed adsorption principle. In addition, it prevents condensation products with sticky or resinous properties from reaching the filter surface itself and blocking it. Dust and gaseous emissions are thus efficiently and effectively simultaneously deposited on the filter material surface. The additive and emissions mixture on the filter material surface is automatically discharged if necessary.
