Abstract
A coiled electrodialyzer is characterized by that the electrode and the ion exchange membrane are coiled together to make special membrane stack electrode, a diluted water channel unit is composed of anionic and cationic exchange membranes and insulating isolative net sheet and communicated with the side wall of diluted water collecting pipe, a concentrated water channel is formed by inserting an insulating net partition between said membrane stack electrode and diluted water channel unit, and a cylindrical body is formed by coiling around the diluted water collecting pipe.
Description
The present invention relates to a kind of improved coiled electrodialyzer, particularly a kind of electrode is with the coiled electrodialyzer of film one roll set, and this equipment belongs to the membrane separation technique field.
In existing technology, coiled electrodialyzer (seeing United States Patent (USP) 328225) is joined the electric dialyzator that collector constitutes by yin, yang amberplex, net dividing plate, positive and negative electrode and dense, fresh water, and agent structure is the rolling cylindrical structure.Be about to amberplex, the net dividing plate is close in order mutually, is that axial centre rolls into cylinder with the collector pipe of double as one electrode, the outer bread of cylinder is to make the metal shell of another electrode.The said equipment is difficult for sealing, and electric-field intensity is along with middle mind-set housing direction descends gradually, and energy consumption is higher.
The objective of the invention is above-mentioned coiled electrodialyzer is undergone technological transformation, thereby provide a kind of simple in structure, processing and fabricating is easy, and electric-field intensity is even, easily sealing, the coiled electrodialyzer of the new structure that energy consumption is low.
The technical solution that realizes above-mentioned purpose is: sandwich an insulation net dividing plate between a pair of anion and cation exchange membrane, constitute the fresh water flow passage unit, one openend of every fresh water runner is connected with fresh water collector pipe areole, sandwich an insulation net dividing plate between the adjacent two fresh water flow passage units, constitute unit, concentrated stream road, each yin, yang amberplex is close to the formation membrane stack according to the order of sequence mutually with insulation net dividing plate; Sandwiching a foil between two cavity blocks or between two anode membranes, the area of foil is less than the ion-exchange membrane area, be bonded and sealed around two amberplexes of folder foil, being welded with lead on the foil links to each other with outer electrode, also but the foil two sides is brushed dielectric or with a kind of conducting polymer composite, is constituted the membrane stack electrode.Membrane stack electrode, net dividing plate, membrane stack are close to according to the order of sequence mutually, and are that axial centre rolls into cylinder with the fresh water collector pipe.
This coiled electrodialyzer is elaborated with embodiment below in conjunction with accompanying drawing.
Center fresh water pipe 1 is the plastic tube of insulation, and its perisporium offers fresh water gully-hole 13, and every group of gully-hole is opened on the same axis; Membrane stack electrode 6 is that the two sides of pole plate copper sheet and two anion-exchange membranes 15 are close together, and copper sheet is connected with lead, and the area of copper sheet is less than membrane area, copper sheet is sealed in two anion-exchange membranes 15 and constitutes; Fresh water flow passage unit 8 is that the dual-side with a pair of anion and cation exchange membrane 15,16 seals into sealing strip 14, dual-side opening and constitute membrane channels in addition, with an opening edge of membrane channels along fresh water collector pipe 1 axial sealing label on tube wall and openend communicate with the gully-hole 13 of fresh water, another openend of membrane channels is communicated with the import 9 of former water; Unit, concentrated stream road 7 sandwiches insulation net dividing plate 5 and constitutes between fresh water flow passage unit 8 and membrane stack electrode 6; Each membrane stack electrode 6, net dividing plate 5 and fresh water flow passage unit 8 are close to mutually and are that axial centre rolls into cylinder with fresh water collector pipe 1; Said apparatus both had been the main component of this coiled electrodialyzer.This main component is installed in the shell body 4 of two ends band end socket 2, a termination of shell body side is provided with dense water out water receiving pipe 3, and another termination of shell body side is provided with original water inlet 9 and water outlet takes over 10; The lead 12 that also is provided with binding post 11 on the end socket 2 and is communicated with the membrane stack electrode.
This coiled electrodialyzer can use in many series connection.
