Distributor device, in particular for falling film evaporators, and use thereof

A device suitable for uniform division of a fluid into n fluid streams each containing gas and liquid, where n is a natural number greater than or equal to 2, the device comprising:

• (a) an upright cap bounded at the bottom by a plate;
• (b) an entry port arranged in a lateral delimiting wall of the upright cap, the entry port configured to bring about tangential inflow of the fluid entering therein;
• (c) an internal arranged upright in the interior of the cap, wherein the internal:
• (i) together with the interior wall of the cap, forms an annular gap for downflowing liquid,
• (ii) comprises an upper edge that ends above the entry port and below an upper delimitation of the upright cap so that the upper edge of the internal and the upper delimitation of the cap form a passage for downward-flowing gas,
• (iii) has, at the top thereof, at least one upper opening for the downward-flowing gas flowing therein,
• (iv) comprises a lower edge that ends above the plate so that the lower edge of the internal and the plate form a passage for the downflowing liquid, and
• (v) comprises at least one opening at the bottom thereof that is hydrodynamically connected to the at least one upper opening;
• and
• (d) n guide devices, wherein the guide devices protrude through the at least one opening at the bottom of the internal into the internal and the guide devices comprise liquid entry openings and gas entry openings;
• wherein a swirl breaker for the downward-flowing gas stream is arranged in the interior of the internal, the swirl breaker being configured to reduce or eliminate turbulence in the downward-flowing gas stream and to reduce the rotational energy of downward-flowing gas stream.
