CS237233B1 - Evaporator for water solution of crystalizing substances - Google Patents

Abstract

The arrangement is for evaporating an aqueous solution of a crystallisable substance (e.g. artificial fertiliser, sugar, urea) to concentrate this. It comprises a tubular evaporator (1) steam inlet (3), outlet (4), solution inlet (2)) with a top cover (5) having a curved outlet tube (6) through which concentrated solution and water vapour enter into a separator vessel (7) arranged above the evaporator. The outlet (6) is curved such that its orifice points towards the bottom of the separator (with solution outlet (8)). A plate (10) arranged in the orifice is parallel to the boundary plane between the flows of concentrated solution and water vapour. A wedge-shaped element (13) arranged below this plate splits the vapour flow so that the emerging vapour is directed laterally in two directions. Effective separation of vapour from concentrated solution prevents droplets of solution being carried along by the vapour. The arrangement eliminates the need for a droplet collector screen or cyclone.

Claims (2)

237233 SUBJECT OF THE INVENTION An evaporator for aqueous solutions of crystallizing substances, comprising a tubular evaporator, a volume separator mounted thereon, a damper lid with two rectangular cross-sections, characterized in that the lean and liquid stream are pre-distributed to the gaseous and liquid phases to reduce droplet abduction before entering the separator, wherein each of the sleeves (6) is provided with three straight plates (7), two of which are placed under the bottom and below the bottom wall of the sleeve (6) and the third plate is fixed in parallel to the central part of the sleeve (6) and is provided with wedge-shaped inserts (8) pointing sharply into the interior of the sleeve (6) and positioned between the central and lower plates, the sleeves (6) facing the bottom of the separator. 2. The evaporator according to claim 1, wherein the rectangular sleeves (6) are widened in a horizontal plane. Recognized by the invention on the basis of the results of expertise, conducted by the State Committee for Inventions and Discoveries of the USSR, Moscow, SU. 1 drawing
