Device for the UV treatment of flowing fluids
A device for the UV treatment of fluids flowing in a flow channel, including a plurality of cylindrical low-pressure mercury UV emitters arranged in groups in the flow channel. The longitudinal axes of the UV emitters are disposed substantially parallel to one another such that the emitters of a given group are disposed in a plane. At least one elongated sensor arrangement monitors the operating state of the emitters, and is spaced from and parallel to one of the groups of the emitters. The sensor arrangement extends essentially transverse to the longitudinal axes of the emitters of the adjacent group, and is provided with a separate UV sensor for each emitter. At least one unit connected with the sensor arrangement controls and/or regulates the emitters.
1. A device for the UV treatment of fluids flowing in a single flow channel, comprising:
a plurality of cylindrical low-pressure mercury UV emitters that are arranged in groups in said single flow channel, wherein longitudinal axes of said UV emitters are disposed substantially parallel to one another and transverse to the flow of fluid in said single flow channel such that the UV emitters of a given group are disposed in a plane and the direction of the flow of fluid in said single flow channel is entirely transverse to the UV emitters;
at least one elongated sensor arrangement also arranged in said single flow channel and adapted to monitor an operating state of said UV emitters, wherein said at least one elongated sensor arrangement is spaced from and parallel to one of said groups of said UV emitters, wherein said at least one elongated sensor arrangement extends substantially transverse to said longitudinal axes of said UV emitters of the adjacent group, and wherein said at least one elongated sensor arrangement is provided with a separate UV sensor for each UV emitter of that group; and
at least one unit connected with said at least one elongated sensor arrangement and adapted to control and/or regulate said UV emitters.
2. A device according to claim 1 , wherein said at least one elongated sensor arrangement is disposed in a quartz tube.
3. A device according to claim 2 , wherein said quartz tube contains a plurality of said UV sensors.
4. A device according to claim 1 , wherein said at least one elongated sensor arrangement is disposed transverse to a direction of flow of said fluids in said flow channel.
5. A device according to claim 1 , wherein said at least one elongated sensor arrangement is provided with a support plate that carries said UV sensors.
6. A device according to claim 5 , wherein said at least one elongated arrangement is disposed between two groups of said UV emitters, wherein said support plate carries said UV sensors on two oppositely facing flat sides thereof, and wherein said UV sensors of a given flat side of said support plate face a respective one of said groups of UV emitters.
7. A device according to claim 1 , wherein each of said UV sensors is provided with a current/voltage transformer and a digital module, and wherein said UV sensors of said at least one elongated sensor arrangement communicate with said at least one unit via a common data bus.
8. A device according to claim 1 , wherein at least one guide sensor is disposed externally of said at least one elongated sensor arrangement, and wherein said at least one guide sensor detects UV radiation emitted by said UV emitters, relative to which radiation individual ones of said UV sensors are adapted to be calibrated.
