WORKPLACE SAFETY
EFFICIENT DUST PREVENTION WITH ATOMIZED WATER FOG
I
Imagine a really dusty indoor environment. You installed dust extraction equipment but the PM2s and silicon levels are way too high and dust is a constant halo around the lights. The problem with extraction is it is localised, it costs a fortune to install, run and maintain, writes Mike Carter, Director, Mist-Air Dust Suppression Limited.
f you can get a well sealed hood around a machine, the extraction can work efficiently, however ill-fitting guards, conveyor transfer points, the underside of conveyors, trans- porting material to hoppers all lead to leak- ages of materials.
If you have suction vents around the building to collect the airborne dust , all you are doing is en- suring the dust is constantly dragged through the
building to the vents for everyone to breathe. Later in the day when the manual clean up begins, the settled dust again rises into the air simply by being moved, brushed, or driven over by vehicles.
Heavy particles, PM10s and larger are not so much of a problem as they are not so easily ingested and will sink quite rapidly by their own weight. However many of the smaller particles, PM2s and PM1s, can easily be ingested into the lungs and tend to stay in the air permanently. These may also con- tain heavy metals, VOCs,and organic compounds. So what is the answer – fog cannons, rotary atomizers, lines of spray jets in the roof, bowsers driven around the site, vacuum lorries? These will suppress some of the problems, but they also soak the floors, machinery, stock and personnel, increasing the weight of the stock and creating slip hazards.
THE ANSWER IS SIMPLE
mist-air atomizes water into fog so finely that it stays afloat in the air and does not drop to the floor, which keeps everything completely dry. It can be installed to many areas for independent control. Small or large areas are easily covered, for either new builds or retro fits.
It actually prevents dust from forming and stops it
moving to other areas. As fresh dust forms it is con- stantly bombarded with microscopic drops of fog which it adheres to and increases in weight, so is unable to stay airborne.
End of problem – you have clean air without having to use huge electric motors to suck it up and there are no filters to clean, no big electricity bills, and low water usage.
It is just so simple, people just cannot accept that they do not have to spend millions of pounds on complicated dust extraction systems to get a more efficient solution.
mist-air started manufacturing this system over 40 years ago and not only does the company design the system to suit the customer’s building or appli- cation, but it also manufactures, installs and main- tains it for the customer.
Installed in over 6,000 sites worldwide covering recycling sites, EFW, Biomass Power stations, ash handling, brick factories, quarries, tunnelling, foun- dries, papermills, particle board factories, glass recycling, gypsum recycling, plastic recycling, the list is endless. Any material and site mist-air is so confident in its products, that it offers a full money back refund if the customer is not pleased with the system once installed.
