PROCESS ( ALTERNATIVES ) AND GEAR FOR RECOVERY AND CONCENTRATION OF COMPONENTS SORBED IN CAPILLARY-POROUS BODY Russian patent published in 2000 - IPC

Abstract RU 2159153 C2

FIELD: technological processes of separation, specifically, of recovery, separation and concentration of components from capillary-porous bodies, for instance, with use of electric field. SUBSTANCE: invention can be used in various branches of industry concerned with regeneration of filtering material in natural and technological systems and with that of previous cone; granular medium is placed in last cone. First section of filter is connected with inlet pipe line and last section is connected with outlet pipe line; back-flushing filter is connected in parallel with water-purifying filter; this filter has lesser capacity at similar construction. Water-purifying filter is provided with flushing system with discharge pipe line of back-flushing filter including perforated pipe line with perforated branches rigidly connected to it; these branches are evenly distributing over entire length of perforated pipe line running along axis of last cone through thickness of medium. EFFECT: improved quality of purification of water; desalinization and back flushing of filter without interruption of process. 7 cl, 1 dwg
