Device for treating liquids by electromagnetism and stirring
The invention relates to a fluid treatment device comprising a stirring element and at least one magnetic device. The stirring element has a plurality of flutes within its central portion, and the magnetic devices are placed around the stirring element. The device can further comprise a UV irradiation module and an on-line analysis module.
1. A fluid treatment device adapted to treat a flow of a fluid comprising a stirring element of a stirring element's length (L) and at least one magnetic device, wherein the stirring element has a plurality of flutes within its central portion along a central length ( 1 ), wherein the plurality of flutes are disposed offset from one another along the stirring element, so as to divide the flow of the fluid as it passes from one flute to the next in a disruptive manner so as to cause disruption of a vortex type in the flow of the fluid, and wherein the at least one magnetic device is disposed around the stirring element at locations that do not have the plurality of flutes.
2. The fluid treatment device as claimed in claim 1 , wherein a South-North field lines generated by the at least one magnetic device are oriented parallel to a longitudinal axis of the stirring element.
3. The fluid treatment device as claimed in claim 1 , wherein the at least one magnetic device has a plurality of permanent magnets of annular shape and radial polarity, and at least one interposed metal element.
4. The fluid treatment device as claimed in claim 1 , comprising at least two magnetic devices disposed on either side of a section of the stirring element that is provided with the plurality of flutes and has the central length ( 1 ), such that a magnetic field generated by the at least two magnetic devices interact with one another.
5. The fluid treatment device as claimed in claim 1 , wherein the plurality of flutes of the stirring element are paired up such that orientation of the plurality of flutes of one and a same pair is opposite to one another.
6. The fluid treatment device as claimed in claim 1 , wherein several sets of flutes are disposed along said stirring element.
7. The fluid treatment device as claimed in claim 1 , wherein the plurality of flutes are of helical shape.
8. The fluid treatment device as claimed in claim 1 , wherein the stirring element is transparent to ultraviolet (UV), and wherein said fluid treatment device also comprises a UV irradiation module disposed outside the stirring element.
9. The fluid treatment device as claimed in claim 8 , wherein the stirring element is partially covered with a film that reflects the UV, and/or wherein walls of the UV irradiation module surrounding the stirring element are covered with said film that reflects the UV.
10. The fluid treatment device as claimed in claim 1 , also comprising a module for analyzing at least one parameter on-line by means of an analysis device, and bypass pipes.
11. The fluid treatment device as claimed in claim 1 , wherein said fluid treatment device is integrated in a pre-existing installation.
