摘要:
A method of varying the flow in a flow conduit from both the anolyte disengager and the catholyte disengager to each appropriately corresponding electrode is provided to selectively vary the flow rate of electrolyte fluids through the disengagers to the appropriate electrodes to thereby control the level of foaming of the electrolyte fluids within the disengagers to prevent the blowover of foam during the separation of entrained gas from the electrolyte fluids therein.

A novel electrode for a monopolar filter press cell is disclosed which comprises a first foraminous surface and a second foraminous surface positioned in parallel and spaced apart, which are secured to conductor rods positioned in a cell frame. The frame has two side members, a top member and a bottom member attached to the first and second foraminous surfaces. A chamber is formed between the first and second foraminous surfaces and bounded by the frame. At least one pair of conductor rods pass through one of the side members of the frame into the chamber. One of the conductor rods in each pair is attached only to the first foraminous surface; the other conductor rod in the pair is attached only to the second foraminous surface. The frame has inlets and outlets for introducing fluids into and removing electrolysis products from the chamber. The novel electrode provides controlled fluid flow up through the electrode chamber to be maintained at desired rates while controlling the ratio of liquid to gas in the upper portion of the electrode to minimize or eliminate foam formation in the cell.

A diaphragm cell is provided having a continuous net between the anodes and the diaphragm. The continuous net permits the minimum anode-cathode spacing to be employed while maintaining uniform anode-cathode spacing throughout the cell. In addition, the diaphragm is retained and prevented from adhering to the surface of the anodes.Employing the diaphragm cell of the present invention in the electrolysis of aqueous alkali metal halide brines results in lower electrical energy requirements and reduced operating costs.

A method of assembling an electrolytic membrane cell is disclosed. The method includes the steps of conditioning the membranes with a conditioning fluid, assembling a vertical stack of horizontal electrode frames with a horizontal membrane sheet between each pair of frames, applying pressure to vertically compress the vertical stack, rotating the compressed vertical stack from a vertical orientation through approximately 90.degree. in which orientation of the stack is called a "pack", connecting the pack into an electrical circuit and to raw material supply lines and product withdrawal lines and then electrically operating the pack while maintaining the pack in a horizontal orientation.
摘要:
In a filter press membrane electrolytic cell having a plurality of electrodes, each electrode being of predetermined thickness and separated from the adjacent electrode by an ion-selective permeable membrane all supported by a frame and in fluid flow communication with a gas-liquid disengager there is provided an improved electrolyte return line having a first portion external to each electrode and a second portion internal to each electrode, wherein the second portion fits within the predetermined thickness in a structurally reinforcing manner so that the structural rigidity of the electrode is increased while the electrode surface area available for fluid contact is maximized.
摘要:
An improved frame component for a frame of an electrode useful in a filter press cell having a channel or U-shaped configuration comprising an outer planar wall attached orthogonally to first and second planar side walls with a multiplicity of spaced rigid reinforcing members attached to first and second side walls.
摘要:
An intercell connector system is disclosed. The system includes two adjacent terminals attached to two adjacent cells and intercell connector selectively overlapping the adjacent ends of the terminals. The intercell connector includes a conductive first member and a second member which are held together by a fastening device which can be selectively loosened and tightened. When the fastening device is loosened, the two members are adapted to be moved out of engagement with one of the terminals thereby disconnecting the electrical circuit between the terminals.
摘要:
A method and an apparatus for controlled, low current start-up of one of an electrical series of membrane electrolytic cells in which the currents through all but one of the remaining cells of the electrical series are unaffected. The method involves placing the cell to be started-up in electrical series with a variable resistor and placing the cell and resistor combination in parallel with the following or preceding one of the remaining cells in the electrical series and then slowly decreasing the resistance of the variable resistor over a preset time period so as to gradually increase the current to the cell being started up and finally eliminating the variable resistance altogether and reconnecting the cell being started-up in electrical series with the remaining cells.
