Definitions
- the invention relates to a method for preventing stray currents in peripheral Plant parts in an electrolysis, wherein an electrolyte line from the exit of a Electrolysis device to a collection container and from this back to the entrance of the electrolysis device.
- the difference is electrical DC voltage between the output electrolyte line and that to the input leading line at least 3 volts and preferably at least 10 volts.
- the invention has for its object that by the lead and the derivation prevent flowing electricity in a simple and reliable manner, so that at relatively high electrical voltages in the electrolysis device the peripheral plant parts outside the electrolysis device can be avoided.
- This is achieved according to the invention in that the electrolyte from the outlet of the Electrolysis device is guided to a first container, which is higher than a second Is arranged that the electrolyte collected in the first container by a first Suction lifter line periodically flows into the second container that in the second container collected electrolyte periodically through a second siphon line into one Collector tank that is arranged lower than the second tank the outlet end of each siphon line at a distance above the liquid level of the container located underneath and that the electrolyte is only ever in one of the flows in both siphon lines or in no siphon line.
- This leads to permanent interruption of the current flow in the peripheral area between the exit and entrance to the electrolysis plant.
- Would you instead switch from Valves working could already have small amounts of electrolyte covering the walls in the valve wet
- the method can be used in electrolysis plants of various types, e.g. B. metal extraction, metal refining, electrosynthesis or Serve electroplating.
- Electrolysis device 1 includes an electrolysis device (1) with a Voltage source (2) for direct electrical current. Electrolyte comes from the Storage container (3) and is led by the pump (4) to a preheater (5), before it enters the electrolysis device (1) through the feed line (6).
- the Electrolysis device can e.g. comprise one or more electrolytic cells.
- Used electrolyte leaves the device (1) through the discharge line (8) and becomes through the pump (9) usually continuously into a first container (10).
- the first container (10) is arranged higher than a second container (11), so that Electrolyte from the container (10) periodically through a siphon line (12) in the can drain second container (11).
- the electrolyte flows from the second container periodically through its siphon line (13) back into the reservoir (3).
- a certain amount of used electrolyte is removed from the process, and fresher Electrolyte is supplied later, but this is not shown for simplification.
- the outlet end (12a) or (13a) is lower than the respective inlet opening of the line (12, 13).
- Each of the two containers (10) and (11) has an upper fill level (A) for the Electrolytes, in which the electrolyte through the respective siphon line (12) or (13) begins to flow outwards and downwards. Due to the viscosity of the liquid and the effect of gravity causes the electrolyte to flow until the level is reached (B) is reached where line (12) or (13) is no longer immersed in the electrolyte.
- the Electrolysis device replaced by a water supply.
- t is the Timeline.
- the container (10) holds a maximum of 1l; together with the quantity flowing in from the water supply at the same time, the fill level in the container (10) decreases from maximum (A) to minimum (B) for 26 seconds; in FIG. 2 this is the time span between t 0 and t 1 .
- the amount of water flowing into the second container (11) is not sufficient to start an outflow through the line (13).
- a quantity of water coming from the reservoir (3) and pumped by the pump (16) is required for this during the period between t1 and t2.
- the fill level (A) in the container (11) is reached, so that it can drain through the line (13).
- the fill level in the container (11) drops from (A) to (B). Between the times t3 and t4, water flows neither in the line (12) nor in the line (13). Then, from time t4, the fill level in the container (10) has reached the height (A) again and liquid flows again through the line (12) into the container (11). The explained up and down of the fill levels now begins anew, the time t5 corresponding to the time t1.
- the hatched areas indicate that liquid flows in one of the lines (12) or (13), as a result of which an electrically conductive connection is established with the container underneath. Since the flow through both lines never occurs simultaneously, there is an electrical current flow between line (8) and line (6), cf. Fig. 1, made impossible.
