The grey cast iron or nodular cast iron of tools for the automotive industry releases fine dust and separates corresponding odours. And in this context it is important to reduce emissions as far as possible. Gießerei Lößnitz GmbH has invested 5 million euros in an economical and future-oriented system of foundry dedusting and odour separation. This protects residents, employees and, of course, the environment from harmful emissions, fine dust and odours.
The exhaust air purification of the Kappa Ekon® filter system collects the emissions at 17 extraction points on the hall ceiling. The purified air is then blown off into the environment by a fan through a chimney 38 meters high.
In order to improve the fresh air in the working area, the preconditioned fresh air is transported to the workplace in the foundry hall. This supply air is heated by the recovered waste heat of the melting furnace.
In the core area of the plant, the new filter system is used for the separation of industrial dusts. The new filter system requires only half the space of conventional solutions and is capable of reducing the residual dust content by half. This reduces energy consumption by one third. Precisely fitting modules were prefabricated in the factory and then assembled on site. This prevents leaks and malfunctions.
The new filter system provides a flow-optimised air supply. The air supply and the air discharge are to be understood here as one overall concept. An efficient exhaust air purification system is installed upstream of the extracted fine dusts and gaseous substances with a precisely defined quantity of reactants. This binds the odour emissions in the entrained flow phase and also on the filter element itself. After this process, part of the adsorption additive already used, which still has a corresponding absorption capacity, can be recycled via the recycling plant and reintroduced into the raw gas stream. This saves disposal costs and protects the environment by reducing the consumption of fresh adsorbent.
And what is the result of this investment of 5 million euros for a new filtration system? The highest air quality far below the legal limits and the greatest possible economy and resource efficiency. And that in turn means good air for employees and local residents. Filtered from odours and fine dust using the latest technology.
Kappa Filter Systems GmbH
Kappa Filter Systems is a leading international manufacturer of systems and plants for industrial air pollution control and energy recovery. Kappa has specialized in the most complete separation of industrial emissions possible from an economic point of view, while at the same time minimizing energy consumption. These two principles also describe Kappa's basic philosophies of "Zero Emissions" and "Zero Waste of Energy". They ensure the highest air quality far below the legal limits and combine the greatest possible economy with resource efficiency. Kappa also relies on high-quality and aesthetic industrial design.
