In industry, fine dust or suspended dust is generated during numerous processes such as transport, conveying and mixing of dusty materials, thermal processing of metals or other materials such as casting, cutting or welding, and mechanical material processing such as grinding.
To protect people and machines, it is therefore important to extract welding, plasma and laser fumes as close to the source as possible and not allow them to escape into the environment. Today, there are numerous options and technologies for individual solutions in every working environment.
Each dust collection system is unique and individually adapted to what needs to be filtered and protected. Depending on the manufacturing processes, welding fumes, powder coating emissions, grain dust, oil mist and much more are generated. At the beginning of the planning process, it is therefore important to know exactly all the details in the process, such as:
The better the knowledge of this, the more accurately and efficiently the dust collection strategy can be determined and the right choice of dust collection equipment can be made.
The most widely used dust collectors are
Of course, the separation of dirt particles is also possible by mechanical means, but due to their low efficiency, these systems are usually only used as pre-separators. These are e.g.
However, before turning to separation and filtration, the collection, extraction or capture of the dust in question must be solved. It is not always possible to remove the dust immediately where it is generated. Therefore, the movement and transport through ducts and pipes must be planned to be as efficient and space-saving as possible.
However, how dusty air is extracted is not described in any standard or regulation; only the laws of physics apply. In addition to complicated calculations from physics, the knowledge gained from years of practical experience is therefore the best guarantee for a successful extraction system.
Industrial dust collection systems require a high degree of professionalism, experience and up-to-date technical knowledge, especially in the planning phase.
As part of a structural components project, one of the most modern production lines in Europe has been built at the Hungarian Prec-Cast plant of the German Wolf Group. The goals of this project were lean production, small buffer volumes, fast cycle and throughput times, and high line availability.
Push-Pull is a solution that has proven itself very well for keeping the ambient air clean in production halls and everywhere where the selective collection of polluted air is not possible.
