Industrial extraction system for a very dusty transshipment site

The transshipment of bulk goods involves a large mass flow; and depending on the product, a lot of dust may be generated. Excessive dust production is of course undesirable in any process, but especially when it comes to bulk goods whose dust is harmful to the environment.

If the bulk material is dusty and non-inert, it is likely that strict environmental standards must be met. Proper extraction of the windblown dust released during transshipment is essential to meet these standards.

Naaykens has extensive experience with:

  • Proper sizing of extraction capacity based on the process;
  • Possible adjustments to the installation for proper operation of extraction – such as sealing openings with fins and correct positioning of extraction points;
  • Correct dust collection based on type and amount of dust.

Customer request: industrial extraction system for bottom ash

A client of ours had a problem with dust generation during bulk transshipment of so-called bottom ash. The dust generation takes place along the entire length of the plant so our knowledge of Air Technology, filtering, extraction and piping came in handy.

With such installations, Naaykens Luchttechniek has actual experience and ready knowledge for many years. With our in-house production, we can adapt an extraction system precisely to the industrial process. In close cooperation with the customer, our experienced professionals determine the required extraction points, on which the extraction system is designed. In such situations, both the piping and the sizing of the filter are tailored to the customer’s wishes, requirements and needs.

We were proud to relieve this client of all air technical problems, where we were happy to use our expertise to rid the process technical plant of dust problems.

Again, the filtered air is purified of dust and clean enough that it can be blown back into the factory. Blowing air back into the factory is an energy-saving measure in the cold winter months and/or in the summer months, which saves a lot in gas or electricity bills. No cold air needs to be heated in the winter and no hot outside air needs to be cooled in the summer. With the right sound-deadening measures, the installation complies with health and safety requirements and with the customer’s demands.

Determination of appropriate piping - Transfer bottom ash

In the pictures you can clearly see that besides a filter also a lot of piping was needed in this installation. Here we also used our experience to be able to dust the entire hall with one filter.

In this installation, with cleverly chosen piping with one filter, we were able to supply the industrial extraction system at seventeen different points. The fan on the filter was chosen so that the industrial extraction system generated sufficient air velocity in the piping even at the farthest point so that the dust did not remain in the piping.

How we determine this piping and balance the entire extraction system so that the chosen solution is also the best for your process we will be happy to explain.

Modular construction of the dedusting system

In this filter it is also easy to see how with our modular built filters a large reliable industrial extraction system can be built in a short time. This method of construction makes it easy to build a large extraction system, both in terms of technical drawing and the physical assembly of the filter, for example.
The modular components can be assembled quickly and easily on site, saving valuable time for assembly.

In designing this industrial extraction system, a special single large fan was chosen next to the filter, and a central dust discharge via screw conveyor and rotary sluice. A piece of engineering will always remain, but by making the filter out of standard modular blocks, half of the designing is already done, even before YOU order.
