The Scheuch IMPULS filter is a high-capacity filtering separator that delivers outstanding cleaning performance combined with an excellent degree of separation. It is used for the dry separation of solid matter, primarily in the extraction of contaminants from machinery and the workplace, as a process filter in material recycling, or for conveyed material separation purposes.
Thanks to the specially shaped twin nozzles on the jet pipe, the pulsed free jet pulls along an envelope of clean gas from the primary compressed air as it makes its way to the injector. The two gas flows are mixed in the injector by means of pulse exchange and, at the same time, experience a significant increase in pressure. This ensures highly efficient cleaning throughout the bag length and filter bags that require cleaning less frequently.
Proven in practice for decades, the IMPULS cleaning system has become a byword for low operating costs:
A plant's ability to demonstrate a high level of safety and reliability is essentially dictated by its key components. The radial fan is one of the components at the heart of every extraction, dedusting, exhaust and flue gas purification, and pneumatic conveying plant. It helps to meet customer requirements with a level of quality that guarantees fault-free operation and excellent performance between maintenance intervals.
When it comes to ensuring availability and operational safety in dedusting plants, conveying mechanisms are just as crucial as fans and filter systems.
All conveying mechanisms can also be used in explosive, dust-laden atmospheres as defined in Directive 94/9/EC (ATEX).
In the cement industry, rotary valves are used as continuous discharge or dosage devices with slight negative pressure/overpressure for air exclusion purposes. The advantages of rotary valves lie in their comparatively low construction size combined with a high, speed-dependent conveying output, their ability to be used in a wide range of temperatures and with various pressure differences, and the relatively low energy costs associated with them.
Tube-type and trough screws are used to continuously transport bulk materials, at throughput volumes of 2 to 500 m³/h and with screw diameters between 200 and 1000 mm.
The longer the material conveying path and the higher the quantity of material that needs to be transported, the more sensible a choice high-pressure systems become. The main components of these are a high-efficiency rotary blower plus a rotary valve and an injector. Together, they ensure efficient conveying even when dealing with significant material quantities. High-pressure systems are ideal for use with conveying quantities of 1 to 100 t/h, conveying systems of up to 1500 m in length, and nominal widths between 88 and 500 mm.
Material loading stations consist of a rotary valve with an injector directly attached to it. The rotary valve loads the material into the pneumatic conveying system in a controlled manner. If it needs to handle items that cause wear, the system can also be lined with special materials.
