Abstract
A frame carries an electrode stack on pivots so that the stack can be assembled and maintained in horizontal position and operated for treating a fluid stream in vertical position with upward flow. Plates of the electrode stack are lined on minor edges by molded-on, non-reactive extensions to protect against wear during the reaction process. The extensions carry integral interplate spacer portions and integral interplate seal portions to eliminate misplacement of electrode stack elements during assembly and maintenance.
Claims19
An electrocoagulation reaction chamber for performing the electrolytic treatment of a stream of process liquid, comprising:
- an electrode stack containing a plurality of electrode plates and defining a flow path through said electrode stack for passage of a stream of process liquid to be treated;
- a supporting frame carrying the electrode stack;
- and
- a base carrying said supporting frame for pivotal movement with respect to said base, such that the electrode stack can be disposed in at least two pivotal positions with respect to the base, wherein a first of said two positions is substantially horizontal and the second of said two positions is substantially vertical;
- whereby the electrode stack can be disposed in said first position for maintenance and can be disposed in said second position for conducting electrolytic treatment of a stream of process liquid.
A method of treating a stream of process liquid by electrocoagulation, comprising:
- providing a base suited to carry an electrode stack for pivotal movement between a horizontal position and a vertical position;
- assembling a plurality of electrode plates to form said electrode stack on said base in said horizontal position, wherein the assembled electrode stack includes an inlet end for receiving a stream of process liquid and an outlet end for discharging said stream of process liquid;
- and wherein said inlet end is positioned with respect to said base such that the inlet end is at the bottom of the assembled electrode stack when pivoted to said vertical position;
- providing a source of electric current to said electrode stack for treating process liquid passing therethrough;
- pivoting said assembled electrode stack into a vertical position with said inlet end at the bottom of the stack;
- directing said stream of process liquid into the electrode stack through said inlet end for upward flow;
- treating said stream of process liquid while in the electrode stack by applying electric current from said source thereof to plates of the electrode stack;
- discharging process liquid from said outlet end;
- pivoting the electrode stack from vertical to horizontal position;
- and
- disassembling the horizontal electrode stack.
An electrocoagulation reaction chamber, comprising:
- at least first and second electrode plate assemblies in face-to-face alignment;
- said first plate assembly includes a first reactive metal plate suited for use in an electrolytic reaction, a first peripheral extension formed of nonreactive material, and an integral interplate spacer defined on at least one major face thereof and formed of nonreactive material;
- and
- said second plate assembly includes a reactive metal plate suited for use in an electrolytic reaction, and a second peripheral extension formed of nonreactive material and suitably configured to abut said integral interplate spacer of said first plate assembly.
