The filter Venturi consists of two basic elements:
- the Venturis where the contact phase between liquid and the air to be scrubbed is produced.
- A cyclone separator where the separation of air and droplets that captured dusts occurs.
Dusty air, drawn by an high pressure fan, passes through the ven-turi orifices where it undergoes a substantial increase in speed while the water, recirculated by a pump, is introduced in the throats. The rapid acceleration of the air causes the atomization of water into millions of fine droplets that captured the pollutant dusts. The mixture of dusty air and water is introduced tangentially in the cylindrical body of the separator, in which spiraliform movements take place. The centrifugal force pushes the water droplets against the wall surfaces, while the scrubbed air is released upwards. Depending on the incoming pollutant substance an adequate clea-ning/filtration system must be used to keep the water inside the tank in good conditions. This solution will keep a functional system with steady scrubbing over time.
Inside the soundproof frame the fan, the hydraulic system and the filter for the reciclated water.
Are placed while the control board is placed out of the machine.
This filter is suggested in production processes that produce dusts undissolvable in water (metals, Compounds, resins, inerts) or that produce burning parcicles that could generate fires or explosions in the dry filters.
In case it is necessary to absorbe dissolvable dusts or dusts gene-rating aluminothermy cases (aluminum for instance), the use of Venturi has to be studied with our Techncial Dept in order to calcu-late the application with the suitable optional devices.
