Reither - Model LN 115 -Venturi Scrubber System

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 design of the slot tube Venturi scrubber System REITHER is demonstrated in Fig. 2. After entering into the scrubbing housing (1) the gas to be cleaned flows through a narrowing, built by two traverse pipes (2) and a displacer (3), fixed on a lifting rod. The double split (4) resulting, can be changed by manual or automatic continuous adjustment of the displacer. By this accommodation of the split width – also in running operation – a high flexibility at occurring load variations is guaranteed. Addition of scrubbing liquid is done via a compression nozzle (5). An even distribution of drops in split is guaranteed by both rectangular Venturi throats.

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.)
