Definitions
- the treated fluid can however be a gas such as air or a liquid other than water.
- the chemical or organic pollutants present in a fluid can be eliminated in the sense of purification, either by passive processes of the filtration type, or by active processes involving technologies aimed at transforming the pollutants into neutral products.
- active processes involving technologies aimed at transforming the pollutants into neutral products.
- the objective of the present invention is to propose a device for purifying fluid making it possible to obtain significant gains in efficiency of consumed power, and to pass significant flow rates in a very compact device.
- It consists of a helical Xenon impulse lamp with one or more turns emitting photonic radiation from the bottom ultraviolet to infrared without discontinuity, and mounted on a cylindrical quartz tube through which the fluid to be treated passes, this lamp possibly being associated with a longitudinal lamp of the same type immersed in the center of the tube, the assembly being arranged in an enclosure whose internal walls reflect ultraviolet radiation.
- FIG. 1 represents the system as a whole
- FIG. 2 is an enlarged axial section of the enclosure
- FIG. 3 represents, under the same conditions, an alternative embodiment comprising a submerged irradiation lamp and a propeller intended to make the flow of the treated fluid cyclonic
- FIGS. 4 and 5 are longitudinal sections of two alternative embodiments of passage of the fluid.
- FIGS. 1 to 3 consists of an enclosure 1 forming the treatment cell and an electrical supply module 2.
- the enclosure 1 is crossed by the pipe 3 through which the fluid to be treated passes and contains the irradiation lamp or lamps 4, 5.
- This enclosure preferably cylindrical, will be made up, or coated on the internal face 6 of its wall , of a material likely to favor the reflection of the wavelength range included in the range of ultraviolet (UV) radiation. It will advantageously be pure aluminum, of which the oxide layer has a UV reflection rate close to 80%.
- Photonic radiation is obtained by means of at least one helical lamp 1 with concentric irradiation mounted on a cylindrical tube 7 through which the target fluid passes, and made of transparent quartz at the desired wavelengths for the targeted treatment. This principle allows significant gains in power consumption efficiency and allows large flows to be passed through a very compact device.
- the concentric irradiation principle offered by the helical arrangement of the lamp or lamps allows all options in terms of photon coupling. It is indeed possible, depending on the extinction coefficient due to the absorption of the radiation by the target fluid, to compensate for the loss by an additional irradiation provided by an additional lamp 5 immersed in the center of the quartz tube 7. This eccentric emission lamp then allows an increase of approximately 65% in the flow rate admissible for equivalent treatment (thickness of the fluid crossed increased by approximately 30%).
- the tube 7 for the passage of the fluid is in the form of a section of short length and of large diameter relative to that of the pipe 3.
- This configuration allows the fluid to slow down considerably due to the large section of the treatment area without requiring a lamp 4 of significant length, said lamp can advantageously be single-turn.
- the major advantage of this arrangement is to increase the time of presence of a unit volume of fluid with regard to photon irradiation.
- the tube 7 has a central inlet and peripheral outlets so that the path of the fluid takes place from the center outwards, therefore from the highest surface energies to the lowest, at the periphery.
- the equivalent inlet and outlet sections will consist of a multitude of holes promoting turbulence and control of the average path of each elementary volume of fluid.
- the device may include a peripheral tube 8 for the passage of the fluid, external to the lamp 4 and whose role is to allow an increase in passage section of the order of 25% and therefore an increase in flow rate of approximately 50% (Figure 5).
- the lamp (s) 4, 5 are xenon-type flash lamps emitting impulse light spanning a spectrum from low UV to visible, and offering an extremely favorable yield in the energy conversion from electricity to l 'optical.
- the purifying effect is then obtained by UV emission (germicide) supplemented by the visible energy density generating a shock wave linked to the relaxation of the photonic discharge.
- the concentration of this flash over a period ranging from 100 microseconds to 100 milliseconds provides a density of photonic energy making it possible to pass through a layer of fluid compatible on the one hand with the flow rates to be treated and, on the other hand, with their content in suspended solid particles defined as average turbidity.
- the electrical morphology of the current pulse generating each flash is such that it allows a yield between 2 and 15% in the so-called germicidal spectrum, which is the absorption spectrum of DNA, centered on the wavelength of 257 nanometers.
- the aging control of the lamp (s) may be supplemented by a sensor 9 of the UV diode type integrated in the wall of the enclosure 1.
- the latter may advantageously include a propeller 10 immersed in the supply line.
- This swirling effect of the flow in the cell in a turbulent manner brings an increase in the processing efficiency since it can then be considered that any target particle passes at least once as close as possible to the lamp (s) , and that the average path of an elementary volume is substantially lengthened, thereby increasing the time of presence and favoring the dose of integrated radiation.
