SORPTION FILTER Russian patent published in 2013 - IPC B01D25/00 

FIELD: process engineering.

SUBSTANCE: invention relates to devices intended for removing effluents of suspensions, superfluous and harmful impurities in industry, agriculture, etc. Sorption filter comprises case 1 filled with sorbent and electrodes 8, 9 to separate sorbent layers in case 1 and to create electrochemical current sources. Sorbent is selected from the group of polarising dielectrics and is fitted in, at least, two sealed vessels 6, 7 arranged in case 1 in the form of helix while electrodes 8, 9 represent an insoluble material. Sealed vessels 6, 7 may represents bags sewn be vertical interrupted stitches. Note here that vessel thickness as-filled makes 20-40 mm. Electrodes may be made of stainless steels, preferably, chrome-nickel steels and composed of grate of high-alloyed stainless steels with mesh of 1.0-5.0 mm in clear and wire diameter of 0.5-1.5 mm. Positive-potential electrode 8 may be made from elastic graphite sheet reinforced by stainless steel or from minced graphite arranged in sealed band sewn by vertical interrupted stitches. Bags 6, 7 may be filled with silica gel and/or haydite or diatomite.

EFFECT: higher efficiency of cleaning.
