 werden, wodurch die angesaugte Luftmenge variiert werden kann und die Anlage unterschiedlichem Wasserdruck bzw. unterschiedlicher Durchflussmenge angepasst werden kann. 



   Mit Hilfe eines nachfolgenden geringen Widerstandes im wasserführenden Rohrsystem, welcher in diesem Ausführungsbeispiel durch die Stauwirkung der angeströmten Stirnseiten der nach der Engstelle befindlichen Elektroden --5-- gebildet wird, entsteht eine turbulente Wasserströmung, in diesem Falle, bei rundem Rohrquerschnitt, eine ringförmige Wasserwalze, die sich etwa kurz nach der Engstelle bis in den Bereich zwischen beide Elektroden erstreckt, durch die der beabsichtigte Effekt der bestmöglichen Durchmischung der entkeimenden Gase mit dem Wasser erzielt wird. 



   Die Ausführung kann auch von den beschriebenen Anordnungen abweichen, soferne nur der Querschnittsverengung im wasserführenden Rohrquerschnitt ein Saugeffekt erzielt wird, welcher zur Ansaugung von Luft verwendet wird, sich durch einen nachfolgenden Widerstand eine turbulente Wasserströmung bildet, und diese die Vermischung der zur Entkeimung notwendigen Gase mit dem Wasser bewirkt. 



   PATENTANSPRÜCHE :

 EMI2.1

 whereby the amount of air sucked in can be varied and the system can be adapted to different water pressures or different flow rates.



   With the help of a subsequent low resistance in the water-carrying pipe system, which in this exemplary embodiment is formed by the damming effect of the flow-through end faces of the electrodes located after the constriction --5--, a turbulent water flow is created, in this case, with a round pipe cross-section, an annular water roll which extends approximately shortly after the constriction into the area between the two electrodes, through which the intended effect of the best possible mixing of the disinfecting gases with the water is achieved.



   The design can also deviate from the arrangements described, provided that only the cross-sectional constriction in the water-carrying pipe cross-section produces a suction effect, which is used to suck in air, a turbulent water flow is formed by a subsequent resistance, and this is the mixing of the gases required for disinfection causes the water.



   PATENT CLAIMS:
1. Process for ozonating water by electrolysis, with arranged in the water flow
 EMI2.1
 Liquid pressure, in particular at a negative pressure point, is supplied in the area of a constriction of the flow expediently located in the vicinity of the electrodes.

Claims (1)

2. Vorrichtung zur Durchführung des Verfahrens nach Anspruch 1, dadurch gekenn- zeichnet, dass zur Einführung der Luft in ein den Wasserstrom führendes Rohrstück (1) eine an sich bekannte, die Engstelle bildende venturirohrartige Düse (4) angeordnet ist, die koaxial von einem mit der Atmosphäre in Verbindung stehenden Luftzuführungsrohr (3) durchsetzt wird, das im abströmseitigen, sich in Strömungsrichtung erweiternden Teil der Düse ausmündet. EMI2.2 rohr (3) im Bereich des abströmseitigen Teiles der Düse (4) in Ansaugrichtung der Luft eine konische Erweiterung aufweist und axial verstellbar ausgebildet ist. EMI2.3 venturirohrartige Düse (4) in Strömungsrichtung des Wassers gesehen vor den Elektroden liegt. 2. Apparatus for performing the method according to claim 1, characterized in that a known per se, the constriction forming venturi tube-like nozzle (4) is arranged to introduce the air into a pipe section (1) leading the water flow, which is coaxially from a is penetrated by the air supply pipe (3) in communication with the atmosphere, which opens out in the downstream part of the nozzle which widens in the direction of flow. EMI2.2 tube (3) has a conical widening in the area of the downstream part of the nozzle (4) in the suction direction of the air and is designed to be axially adjustable. EMI2.3 Venturi tube-like nozzle (4) seen in the direction of flow of the water in front of the electrodes.
