EXTRACTION HOODS

Secondary collection of exhaust air

Producing and processing metals generally creates significant exhaust air volume flow rates – with energy consumption and contamination levels to match.

In this sector, not all processes or treatments can be directly coupled to or enclosed in extraction devices. This means that emissions (dust, waste heat, gaseous substances, etc.) have to be collected using secondary methods – that is, at a location other than the point where they arise – in order to achieve the desired level of air quality in the working area or environment in question. The emission stream dilution associated with this technique determines the required collection flow volume and therefore has a direct impact on the investment and operating costs for the dedusting plant.

Scheuch adopts a methodical approach to determining the characteristics of the emission stream in a verifiable way (observations are made during operation and then documented and evaluated) and to creating the ideal extraction hood design using CFD, with basic operational conditions taken into account.

IMPULS FILTERS

Outstanding cleaning performance combined with an excellent degree of separation

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.

The patented IMPULS cleaning system

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 an, at the same time, experienceing significant increase in pressure. This ensures highly efficient cleaning throughout the bag length and filter bags require cleaning less frequently.

Proven in practice for decades, the IMPULS cleaning system has become a byword for low operating costs:

  • Low compressed air consumption
  • Long service life demonstrated by filter media
  • Very little maintenance or servicing required

RADIAL FANS

The right plant concept for the perfect fan specification

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 system. It helps to meet customer requirements with a level of quality that guarantees fault-free operation and excellent performance between maintenance intervals.

Drive designs:

  • Direct via engine shaft
  • Via belt
  • Via coupling up to 1,000 kW

There are also three different types of impeller:Laufrad zur Förderung reiner Gase 

  • Impeller for transporting clean gases
  • Impeller for transporting gases and shavings with high dust concentrations
  • Impeller for transporting fibrous material

Radial fans with direct drive up to 132 kW

Despite offering higher performance, this enhanced range incurs costs that are lower by around a third as compared to fans with a coupling drive – it also takes up less space. Even when combined with a frequency converter, it represents a less expensive alternative to fans with belt drives. The range has been designed and calculated in line with the latest findings in the field of fluid mechanics:

  • Drive power up to 132 kW
  • Volume flow rate up to 100,000 m³/h
  • Pressure increase up to 20,000 Pa
  • Conveying temperature up to 250°C
  • Impeller diameter up to 1400 mm
