Membrane plastic electrolytic cell of the bipolar type

Abstract

Improvements to a membrane electrolytic cell of the bipolar type, are based on the configuration of its structure, allowing it to have an independent distribution of brine feeds, since it is possible to visually inspect the flow continuity through the two translucent restrictive hoses. The hoses connect to two upper compartments, wherein the compartments ensure the anodic and cathodic containers collects product discharges and separates the turbulence area from the membrane area. This allows spill through to the translucent annular hose to act as a sight glass. This improvement refers also to a reinforced structure with a bulge, to keep the dividing integral injected plastic plate seal sides of the anode and cathode plastic frame compartments perpendicular to keep the minimal gap between electrodes, required to achieve a lesser voltage drop in the electrolytic cell, involving greater current efficiency and electric power (kWh) savings.

1 . A membrane electrolytic cell of the bipolar type, comprising:
 at least one frame indicating the peripheral boundaries of the cell and wherein it creates a recessed anode compartment along the complete surface of the frame, allowing formation of anode compartments;   a distribution pipe integrated into a side of the frame for creating a feed flow, for allowing brine to flow into the recessed anode compartment by means of a connector and a flow wherein the feed flow is restricted to allow for a requisite time required for an electrolysis reaction to take place and wherein a restriction of current leakage to a distributor of the spent brine such that flow is directed toward an upper portion of the frame and is blocked by an upper left section of the frame which is not in communication with the recessed anode compartment;   an upper right compartment for creating a gases and liquids separation unit that allows the discharge of reacted electrolyte products and gasses by means of holes in communication between the upper right compartment gasses and liquids separation unit and the recessed anode compartment and wherein, the reacted electrolyte product passes through outlet holes from the upper right compartment gasses and liquids separation unit to a sight glass, to discharge to a general collector of cells, wherein the general collector of cells integrated to the frame;   a mesh fabric covering the surface of the cell, including a plurality of electrical contacts in contact a plurality of electrodes, anodes and cathodes;   an upper support of the frame for allowing the separation and sliding of the electrolytic cells with bipolar type membrane as a group along an isolating lower rail of the cells, without losing the vertical position needed to keep the grouping while cell pressing is performed; and   a lower part of the electrolytic cells are integrated with one or more wheels for allowing the sliding of the module for pressing a cell.   
     
     
         2 . A membrane electrolytic cell of the bipolar type, according to  claim 1 , comprising:
 bolts and gaskets that make electrical connection between the union of anode and cathode electrodes and is performed by means of a plurality of holes distributed along the surface of the cell beneath the mesh, in function of the equal number of a plurality of electrical contacts.   
     
     
         3 . A membrane electrolytic cell of the bipolar type, according to  claim 1 , that comprising:
 at least one frame, preferably rectangular creating the recessed cell portion, having integral independent discharges, and a connector for a discharge hose in lower portion of the recessed cell; and   a sample taking device which allows for the analysis of products before they are mixed in the general collector, to determine the efficiency of the reaction in the cell.   
     
     
         4 . A membrane bipolar electrolytic, according to  claim 1 , comprising:
 the at least one frame having a series of holes wherein pins are placed which support gaskets and membranes, and engage other holes in the same position on a second frame to join the two frames with respective anodes and cathodes, without disrupting a seal area of compartments integrated into each frame.   
     
     
         5 . A membrane electrolytic cell of the bipolar type, according to  claim 1 , comprising:
 at least one frame containing an ionic exchange membrane between frames, covering the entire surface of the mesh including the peripheral area forming the lower frame of the cell to seal both sides with gaskets, which also integrally seals with the sections of the upper compartments for products and gasses.   
     
     
         6 . A membrane electrolytic cell of the bipolar type, according to  claim 1 , comprising:
 an injected integral dividing plate for separating the anode and cathode compartments and has an arrangement of bulges or reinforcements that is added with a plurality of distributed integral grid reinforcements.   
     
     
         7 . A membrane plastic electrolytic cell of the bipolar type, according to  claim 6 , wherein the injected integral dividing plate may be plastic, polypropylene or another high mechanic and temperature resistance thermoplastic.
