International standard can be employed in many different ways
Fine and extremly fine dusts are generated in nearly all industrial production processes, for example in crushing, grinding, abrasion, in surface treatment and in transfer points of transport systems.
Formation of dusts
Thanks to its more than 50 years of experience in the planning and design of dedusting plants, Turbofilter GmbH meets the increasing requirements and international emission standards at all times.
TurboJetPulse filterThe TurboJetPulse filter which Turbofilter GmbH has developed constitutes the global dedusting standard. It is employed in many different industrial plants where dusts must be separated from gaseous carriers. Its multiply adaptable principle has demonstrated its value for decades and is consistantly further advanced.
Simple principle with huge effectThe way it works is simple. The contaminated gas is loaded on the filter media from outside. The pollutants are separated at the filter medium by way of filtration so that purified gas escapes at the inside of the filter bag. The particles remaining on the outside have agglomerated to form a so-called filter cake. It is removed via compressed air impulse which is either time-controlled or triggered by differential pressure.
The most important criterion for lifetime of the filters and the purity of the filtered gas is the air-to-cloth ratio. This parameter is defined by the amount of raw gas which is purified by one square metre of filter area. The overall size of a filter is therefore determined by the required filter area, which depends on the individual tasks of the respective filter system.
Filter designThe objective of the design is to achieve an ideal compromise between the required efficiency and the lifetime of the filter, on the one hand, and optimised investment costs, on the other. Numerous factors such as quality and bahaviour of the dust and grain size distribution, operating conditions such as temperature, humidity and availability or filter media and filter system design determine the potential air-to-cloth ratio. Experience is a key requirement for determining the optimum concept.
