DEDUSTING PLANTS


The dust-laden air is sucked into a Venturi type tube. It is thus accelerated into the entrance cone where there are, depending on the case, one or more sprays the purpose of which is to create a curtain of very fine droplets which wet the particles.

Since the mean relative speed between the particles of dust and the droplets is very high in order to overcome by impact the surface tension of the droplets, the result is that all the particles are coated.

Mixing then takes place in a centrifugal turbine consisting of a large number of blades so as to increase the homogeneity of the mixture by impact.
On leaving the turbine, the package of air and water/dust mixture is centrifuged in a separator. The wet particles are pushed up against the sidewall, the air is discharged to the outside.

A number of reducing separators are fitted inside to increase the impact of the particles on the side wall.

The standard Cogemacoustic« dust collector range lies between 5 and 25 m│ / sec..
All these machines are supplied with electronic start-up cabinets allowing control of the start-up gradient to avoid uncoupling of the ventilation ducts.
