ELECTROSORPTION EQUIPMENT FOR SELECTIVELY REMOVING INORGANIC IONS IN WASTE SOLUTION

摘要

PURPOSE: An electrosorption equipment for selectively removing inorganic ions in waste solution is provided to increase electrosorption speed, electrosorption capacity and waste solution treatment capacity, adjust height of working electrode, easily assemble the equipment and fabricate the equipment more economically. CONSTITUTION: The electrosorption equipment is characterized in that a working electrode is formed of a cylinder type rigid activated carbon fiber powder compact so that current or voltage is uniformly distributed in the working electrode, wherein cells composing a multi-cell are formed in a double pipe shape on concentrical axis, an inner part of counter electrode(2) is installed at an outer part of the working electrode(1) requiring wide surface area, and a membrane tube(3) is installed between the working electrode and the counter electrode to prevent oxidation and reduction at the counter electrode and convection to the counter electrode, wherein current collector plates are installed at a concentric outer part of working electrode bed, and wherein the electrosorption equipment comprises a counter electrode supporting lower plate(8) which supports the counter plate, and in which a counter electrode chamber(6) is formed; a working electrode supporting lower plate(9) directly put on the counter electrode supporting lower plate and positioned under the working electrode; working electrode chamber channel lower plates(10) directly put on the working electrode supporting lower plate and contacted with the working electrode supporting lower plate; current collector plates(11,12,13) installed between the working electrode chamber channel lower plates; a working electrode chamber channel upper plate(14) which is positioned on an upper part of the current collector plates, and in which a working electrode chamber is formed; a working electrode supporting upper plate(15) positioned on an upper part of the working electrode chamber channel upper plate; a membrane tube supporting upper plate(16) which is positioned on an upper part of the working electrode supporting upper plate, and in which a counter electrode chamber(7) is formed; a counter electrode supporting upper plate(17) positioned at an uppermost part of the membrane tube supporting upper plate; bolts and current collector rods(18) for penetratingly clamping the plates; and O-rings(19) installed between the respective plates.
