HOW IS AN EXTRACTION SYSTEM INSTALLED AND WHICH ONE IS SUITABLE FOR MY APPLICATION?


Extraction systems are systems that remove harmful air pollutants. Different extraction systems are required depending on the application. As well as mobile and stationary dust extractors for numerous dust types, there are oil mist separators for oil mist and chip separators for chips, for example.

All extraction systems have one thing in common: they usually have the same structure. Find out about the detailed structure and function of an extraction system here.
 

Constructing an extraction system.

COLLECTION

In order to be able to filter the medium, the emissions to be filtered must be collected optimally and efficiently. Extraction arms, hoods or funnels are suitable for this purpose.

PIPE / HOSE SYSTEM

The various extraction points are connected to the extraction system by means of pipe or hose systems (folded spiral pipe, steel pipe).

PRE-SEPARATOR

Pre-separators can be integrated into the extraction system in many ways. Among other things, they can be used to relieve the filter unit in processes with large amounts of dust or chips or as an additional safety measure (e. g. in the case of flying sparks). Examples of pre-separators are impact separators, cyclone separators, spark separators and classifiers.

FILTER UNIT

The filtration of the extracted medium takes place at this station. The filtration can be carried out by a variety of filter systems and filter media, for example dry separator with filter cartridges,pocket filters,bag filters, etc. or wet separator with water as the filter medium.

FAN

The fan generates the required air volume flow and the negative pressure for the extraction of the media. It is designed according to the required operating point. Other vacuum generators are side channel compressors,radial blowers and rotary piston blowers.

CONTROLLER

The task of the controller is to control the engine, to monitor the system and to submit reports, as well as to regulate performance.

THE RIGHT EXTRACTION SYSTEM FOR EACH APPLICATION

In order to find the ideal extraction system for the respective application, a few questions must be clarified in advance.

Depending on the process, the pollutant and the material, the possibilities for achieving the optimal extraction result vary.

Below you will find an overview of all possible factors relevant for deciding on the right extraction system.

FACTORS FOR THE DESIGN OF AN EXTRACTION SYSTEM

  • Normal steel (black steel)
  • Stainless steel
  • Light metals (aluminium, titanium etc.)
  • Plastics
  • Organic dusts (tea, cereals, flour etc.)
  • Etc.

  • Dry, oily
  • Pourable, sticky
  • Fibrous, agglomerating
  • Carcinogenic
  • Combustible, conductive, abrasive
  • Etc.

  • Flying sparks when welding
  • Flying sparks when grinding
  • Flying sparks when sawing
  • Etc.

  • Single point
  • More than one point
  • Production workshop extraction

 

  • How many extraction points are in operation simultaneously and therefore have to be extracted at the same time?

 

  • In the production workshop (directly next to the extraction points)
  • Outside the production workshop
  • In an adjoining room
  • Flexible place of deployment (mobile extraction system)

  • 1-shift operation
  • 2-shift operation
  • 3-shift operation
  • Continuous operation (24/7)

  • Via a dry separator
  • Via a cyclone separator
  • Via a wet separator

  • Circulating air: The air is transported back into the workspace.
  • Exhaust air: The air is released outside.

  • 50 litres per month
  • 20 litres of dust per week
  • 10 litres per hour
  • Etc.

  • Dust collection container at the extraction system (e. g. 100 litre dust collection container)
  • Continuous dust discharge via rotary feeder (big bag)
  • Etc.
