Definitions
- the present invention relates to water misting devices intended primarily for all places requiring a bacteriologically perfect hygiene such as industrial installations requiring misting devices, and concerns in particular a misting device with maximum decontamination.
- the fogging of a liquid, and in particular the misting using water is a cooling technique increasingly used in public places to fight against heat stroke especially during periods of heat wave. It consists in projecting water microdroplets with a size varying from 3 ⁇ to 20 ⁇ using misting nozzles using a high-pressure pump between 45 and 110 bar.
- the contamination process also involves other bacteria or viruses that cause diseases such as SARS or bird flu. These diseases can be transmitted by all aerolization processes such as misting which generate droplets whose inhalation by the respiratory tract generates very serious lethal pulmonary lesions.
- the object of the invention is to provide a misting device in which the liquid droplets provided by the misting nozzles do not contain pathogenic microorganisms.
- the object of the invention is therefore a misting device comprising a misting ramp comprising a plurality of misting nozzles, a liquid source supplying the liquid for supplying the misting ramp, a pump adapted to supply under high pressure, typically between 45 and 110 bar, the liquid from the source to the misting ramp.
- the device also includes at least one particle filter retaining particles having a size greater than about 1 ⁇ and receiving the liquid from the source, an ultrafiltration filter receiving the liquid from the particulate filter to retain microorganisms having a larger size. at 0.2 ⁇ , and a UVC ramp chamber with one or more lamps UVC placed in quartz sheaths receiving the liquid from the ultrafiltration filter and adapted to destroy microorganisms with a size less than 0.2 ⁇ .
- the device further comprises a dosing pump placed after the UVC ramp chamber, the dosing pump regularly supplying biocidal or virucidal products in order to prevent the formation of a biofilm in the pipes between the pump and the boom. misting.
- the embodiment of the misting device illustrated in the single figure is mainly used in industrial installations requiring permanent misting such as paper mills or waste disposal centers, but also in poultry installations or greenhouses. It can also be used in hospitals and retirement homes.
- misting consists of bringing into the air fine droplets of water which are very quickly evaporated. This causes changes in the physical characteristics of the ambient air which result in an increase in hygrometry and adiabatic cooling (that is to say without heat exchange with the outside) by evaporation of the water causing a lowering of the temperature of the atmosphere.
- the nozzles consist of a pressurizing chamber in which is located a finned stainless cylinder.
- the water projected against this cylinder acts as a lubricant by rotating it and breaking up into microscopic particles smaller than 10 ⁇ which are driven outside by the high pressure.
- a flow of air is created to the extent that the hygrometric degree of air in the whole room tends to become uniform. This gives a natural ventilation of the room. Note that it is also possible to install a fan if you want to get faster ventilation.
- the water inlet pipe 11 from the source 10 supplies the water to a series of three filters, two particulate filters 50 and 52 and an ultrafiltration filter 18 followed by a UVC ultraviolet radiation beam 20 (Ultra Purple Type C) to destroy all microorganisms less than 0.2 ⁇ in size and mainly viruses that are too small to be retained by the ultrafiltration filter.
- a UVC ultraviolet radiation beam 20 Ultra Purple Type C
- the first filter 50 is a positively charged filter stopping all particles larger than 4,5 ⁇ .
- the second filter 52 stops all particles and colloidal materials larger than 0.5 ⁇ .
- the ultrafiltration filter 18 retains a large part of the microorganisms, that is to say all those whose size is greater than 0.2 ⁇ and which, otherwise, could screen for microorganisms of infinitesimal size such as viruses that are eliminated by the UVC ramp, and retains in particular the bacteria present in the water.
- the UVC ramp 20 consists of one or more low pressure mercury vapor lamps emitting at the germicidal wavelength of 253.7 to 258 nanometers. These lamps are placed in quartz sheaths. Water circulates in the treatment chamber 20 around the sheaths, quartz. These sheaths serve as separation between the lamp (s) and the liquid as electrical and thermal insulation and allow operation at an optimum temperature.
- An UV meter 32 permanently indicates in percentage with respect to the intensity of the lamp emitted at the beginning of life, the intensity received at the most unfavorable point of the chamber. It is an indicator of efficiency that takes into account all the parameters influencing performance such as lamp aging, fouling of quartz sheaths covering the lamps and the deterioration of the quality of the water.
- the UVmeter can control an alarm device (not shown) that triggers when the intensity emitted by the lamps is insufficient to ensure perfect decontamination of the water.
- An automatic cleaning device 34 may be connected to the UVC ramp chamber 20. This device acts by scraping to remove deposits that may have formed on the quartz sheaths and thus mask the radiation. This device thus avoids the disassembly of the lamps and the emptying of the chamber. It can be triggered according to two modes of operation: either by the intensity decrease of the UVC radiation measured by the UVmeter 32, or by programming a regular cycle which depends on the operating time of the UVC lamps.
- misting ramps can have total lengths of 400 m. It is therefore absolutely necessary to secure the entire device to be able to prevent the formation of a biofilm of microorganisms such as legionella in the pipes leading to the misting ramp by regular treatment by means of a metering pump 53 allowing inject regularly products fighting against the formation of this biofilm. Such products are biocidal compounds destroying bacteria or better, virucidal compounds destroying both viruses and bacteria. In this way, the quality of the water circulating in the device will be equal to that obtained at the exit of the UVC ramp. Since the products supplied by the metering pump 53 can cause rapid shut-off of misting nozzles, it is advisable to add a filter antiparticles 54 for stopping particles larger than 5 ⁇ at the outlet of the metering pump 53.
- the misting device is drained so as to eliminate the slightest risk of contamination.
- all the pipes connecting the elements of the misting device such as the pipe 11 from the source 10 or the pipe 28 connecting the pump 12 to the misting ramp 14 are preferably copper which is a bactericidal metal or alloy of copper.
- the misting device according to the invention can also be used in public places such as motorway areas, railway stations, airport lobbies, or private places such as patios, restaurant terraces, shops, etc. It can also be used in professional sites such as greenhouses, fish stalls, vegetable stalls or humid Aero-refrigerant towers (TAR).
