The Venturi scrubber is a high efficiency wet scrubber suitable for separation of particles up to the submicron range. The advantage of this system is the high collection efficiency, the flexibility regarding fluctuation of load, its simple design and thus favourable in cost, as well as the low-maintenance operating mode.
The function of a Venturi scrubber is based on increase of velocity of a gas flow by narrowing the cross section at simultaneous injection of a scrubbing liquid. The high shear forces between gas and liquid lead to finest distribution of liquid drops which agglomerate with the solid particles. These agglomerates are separated from the gas flow by baffle separation in droplet separator switched in series, because of its inertia of masses.
The main field of application for slot tube Venturi scrubbers is the separation of fine dust and aerosols. Especially exhaust gases with high water content, temperatures near the dew point, adhesive dusts tending to cake or being explosive can be good separated in wet scrubber. A simultaneous separation of gaseous pollutants is also possible. It is best suitable for separation of:
Er eignet sich besonders zur Abscheidung von:
- Acid mists (HCI,H2SO4,SO3,H3PO4, etc.)
- Salt aerosols (NH4CI,NH4F, etc.)
- Metal oxides (Copper, zinc, lead, etc.)
- Fine dust (Metal-, colour pigments-, silicate-, flue dust, soot-, wood-, etc.)
- Oil- and emulsion mists
- Pollution gases (HCl, SO2, Cl2, NH3, HBr, etc.)
