Definitions
- the present invention can be classified in the technical field of electrolyzers.
- the present invention relates to an electrolyzer as characterized in the preamble of claim 1.
- the resulting liquor is separated from the sodium chloride, which is supplied to the anode side, via a cation exchange membrane, and thereby separated from each other.
- a cation exchange membrane Such membranes are known in the art and commercially available from a variety of suppliers.
- the standard potential at the anode, which forms at the end of the above reaction is + 1, 36 V, the standard potential at the cathode at the end of the above reaction - 0.86 V.
- GDE gas diffusion electrodes
- the electrochemical conversion takes place within these electrodes only at the so-called three-phase boundary.
- the three-phase limit is the range at which gas, electrolyte and metallic conductors meet.
- the metallic conductor should simultaneously be a catalyst for the desired reaction.
- Typical catalysts in alkaline systems are silver, nickel, manganese dioxide, carbon and platinum.
- their surface area must be large. This is achieved by fine or porous powder with inner surface.
- the hydrostatic pressure at the bottom of the column is highest, which would enhance the phenomenon described above.
- This problem is, as can be found in the relevant literature, solved in the form of falling film evaporators.
- the liquor is allowed to pass between the membrane and the GDE through a porous medium, thus preventing the formation of a hydrostatic column.
- Percolatortechnologie WO03 / 042430 discloses the use of high density polyethylenes or perfluorinated plastics for these porous ones
- anode and / or cathode is a gas diffusion electrode, between the gas diffusion electrode and the
- Ion exchange membrane a gap, an electrolyte inlet above the gap and an electrolyte drain below the gap and a gas inlet and a gas outlet is arranged, wherein the electrolyte inlet is connected to an electrolyte reservoir and has an overflow.
- the overflow of the electrolyte is intended to ensure a uniform feeding over the full width of the cell.
- the amount of electrolyte flowing into the electrolyte feed from the receiver tank is dependent on the difference in height between the liquid level of the electrolyte in the receiver tank and the electrolyte
- Liquid level in the electrolyte feed dependent.
- the liquid level in the electrolyte feed depends on the height of the overflow, which determines how much the electrolyte in the electrolyte feed is dammed up. If more electrolyte is added than can drain over the overflow channel and the gap, the pressure of the electrolyte increases in the channel-shaped
- Electrolyte feed above the gap By selecting the height of the overflow channel, the pressure in the electrolyte inlet can be adjusted. As the pressure increases, more electrolyte can therefore be passed through the gap and the flow velocity in the gap can be selectively varied. By varying the ratio of the described height differences to one another, the pressure in the electrolyte inlet can be adjusted in a targeted manner.
- an apparatus consisting of several juxtaposed in a stack and in electrical contact standing plate-shaped electrolytic cells is constructed, which has inlets and outlets for all the necessary and resulting liquids and gases. It is therefore a series connection of several individual elements, each having electrodes which are separated from each other via a suitable membrane and which are fitted into a housing for receiving these individual elements.
- electrolyzers are disclosed, for example, in DE 196 41 125 A1 and in DE 102 49 508 A1.
- a polarization can be performed. This is the case, inter alia, when an electrolysis cell is filled and heated to be put into operation. Even if the cell is taken out of the electrolysis operation, the polarization is to be maintained until the chlorine-free state of the anodic liquid and cooling has taken place.
- the polarization current ensures that the metallic
- Components of the electrolytic cell are in a potential range in which no corrosion reactions take place, which lead to the dissolution of the metals that make up individual components of the cell cathode.
- the polarization current must be selected so high that after loss by stray currents through the Elektrolytzu- and processes in the Elektrolyseurmitte still sufficient positive current is present to ensure a defined potential range in which no critical corrosion reactions occur.
- Drain lines of the cell is discharged through the electrolytes, minimized by said constructive measures.
- the inflow of the brine and brine takes place via a conventional inlet distributor.
- Consists of individual electrolysis elements which are arranged in two electrolyzer stacks 2 and 3.
- a polarization current of 27 A is fed on the anode side, so that a total voltage of theoretically about 250 V is obtained without stray current losses.
- FIG. 1C and FIG. 1D show, in detail, the stray currents that are conducted through the electrolyte inlets and outflows for each element.
- stray currents are above the element number, i. the element position in the electrolyser, shown by the brine supply lines
- Fig. 1 D shows for comparison in detail the currents flowing through the Laugeablauf effet (represented by filled triangles) and the
- Anolyte drain line (represented by open triangles) are lost. Disadvantage of this technology is thus that very high stray currents arise, which in turn make high polarization currents necessary.
- the object of the present invention is therefore to provide a construction which ensures a uniform distribution of the electrolyte in the
- Electrolysis operation comprising a plurality of individual electrolysis elements to ensure by a constant pressure in the electrolyte supply structure and sufficient amounts of electrolyte are provided. In addition, it should increased electrical stray currents caused, inter alia, by an uneven electrolyte distribution can be avoided in order to keep necessary polarization currents as low as possible.
