Definitions
- the present invention relates to a mist-decontamination apparatus of the type capable of generating and propelling into a room to be treated with fine droplets of a treatment product forming therein a mist of the so-called "dry fog" type.
- the size of the drops formed is relatively high (of the order of 80 to 200 microns for an air flow rate of 3 to 5 ml of air per minute), so that these drops are deposited by simple gravity effect on the surfaces close to their place of spray, which, of course, is not satisfactory insofar as the surfaces remote from the spray nozzle are free of treatment.
- the injection device is provided with an ultrasonic "resonator" disposed downstream of the outlet of the injector, so that the flow at the outlet thereof is subject to fragmentation. forming a kind of "diffraction" of the drops, having the effect of making them even smaller, which makes it possible to further increase the homogeneity of their distribution.
- the Applicant has also proposed, in the patent application No. FR 09.00134, an injector to ensure even further fractionation of the sprayed droplets in the room.
- Decontamination devices capable of performing this type of misting usually consist of a compressor, in particular an oil lubricant type compressor, which supplies a buffer tank from which, by means of pressure regulating means, feeds an injector device.
- Devices of this type have significant disadvantages.
- the storage of pressurized air in the buffer tank causes, due to the various temperature and pressure fluctuations to which the air is subjected during the process, to generate condensates.
- the user of this type of device is thus forced, on a regular basis, to remove them from the storage tank and their disposal.
- the air leaving the tank passes through a filter which must itself be provided with purge means which must be emptied regularly.
- tanks intended to receive pressurized gases are subject to safety standards which force the user to carry out their control periodically, which does not fail to cause the latter a constraint. and an inconvenience in the operation of the apparatus.
- nationally valid standards are sometimes very different from one country to another, which forces the exporter of these devices to design different storage tanks from one country to another, thus increasing the complexity of the management as well as the costs of these devices.
- the tank in order to be able to dispose at the outlet of the buffer tank, downstream of the regulating means, of a given pressure, in particular of the order of 3.10 5 Pa, the tank must be supplied with a pressure of between two or three times this pressure, ie between 7.10 5 Pa and 10.10 5 Pa, which is a source of energy consumption on the one hand and, on the other hand, of repeated mechanical stresses leading to fatigue of storage tank and its accessories.
- the object of the present invention is to propose a new type of decontamination apparatus which is free from the aforementioned drawbacks.
- the present invention thus relates to a decontamination device of the type comprising a compressor supplying gas under pressure, with the interposition of pressure regulating means, means capable of misting in a room to be treated a decontamination product in the form of fines. droplets, characterized in that the compressor feeds directly the misting means, at a desired operating pressure, and without the interposition of a buffer tank, the pressure regulating means being constituted by a controlled flow leakage between the compressor output and the input of the misting means.
- the apparatus according to the invention will comprise flow leakage control means such that it will become active as soon as the pressure at the inlet of the misting means exceeds the desired operating pressure and the compressor will be of the type permanently operating.
- the compressor will be of the oilless lubrication type.
- the pressure regulating means may consist of a mechanically controlled valve formed of a body provided with an inlet duct and an outlet duct. free air, the placing in communication will be controlled by a valve applied in the non-communication position on a seat by a calibrated spring to a compression value close to a set pressure.
- the pressure regulating means may also be of electronic type and comprise pressure measuring means disposed in shunt on the main pipe connecting the compressor to the misting means, which will be connected to electronic means analysis and control, including a microcontroller driven by a suitable program. This microcontroller will provide control of a valve, including electronically controlled, shunted on the main pipe, so as to control the opening thereof when the pressure in the latter will exceed the set pressure.
- the pressure regulating means will be able to generate a leak whose flow will be greater as the pressure difference between the set pressure and the pressure at the outlet of the compressor will be large.
- the outlet pressure of the compressor can be equal to the nominal value of 3.10 5 Pa. This lower pressure gives it significant advantages and in particular substantial energy savings and optimization. the life of the compressor.
- FIG. 1 is a schematic view of a decontamination apparatus according to the prior art
- FIG. 2 is a schematic view of a decontamination apparatus according to the invention
- FIG. 3 is a diagrammatic sectional view of an example of a valve with mechanical pressure regulation implemented in the decontamination apparatus according to the invention
- FIG. 4 is a schematic view of a variant of a device capable of creating a pressure regulating leak in the decontamination apparatus according to the invention.
- FIG. 1 shows a decontamination apparatus of the type according to the prior art, which is intended to project by misting into the volume of a room to be treated by means of an injector 5 'a product of decontamination in the form of fine droplets.
- This apparatus includes a compressor of the non-permanent operating type, i.e. it is designed to operate intermittently.
- This compressor feeds via a pipe 3 'a buffer tank 4 with the interposition of a control device 6 of the pressure switch type which allows the filling of the tank 4 with air and stops it as soon as the pressure reaches a maximum level, for example 10.10 5 Pa, to reactivate the compressor as soon as the pressure drops to a minimum threshold, for example 7.10 5 Pa.
- a control device 6 of the pressure switch type which allows the filling of the tank 4 with air and stops it as soon as the pressure reaches a maximum level, for example 10.10 5 Pa, to reactivate the compressor as soon as the pressure drops to a minimum threshold, for example 7.10 5 Pa.
- FIG. 2 is a diagrammatic representation of a decontamination apparatus according to the invention.
- This apparatus comprises a compressor 1 of the type able to operate permanently, whose output S_ is connected by a pipe 3, to an injector 5 which comprises suction means 7, by venturi effect, the treatment liquid contained in a storage cartridge 9.
- the means for regulating the misting pressure at the outlet of the compressor 1 consist of a mechanically regulated valve 11 whose outlet 13 is in communication with the atmosphere and which is arranged on a bypass 15 which is struck on the pipe 3.
- FIG. 3 An example of a mechanically controlled valve 11 is shown schematically in FIG. 3. It consists of a body 17 which is hollowed out with an air inlet duct 19 which is closed off by a valve 21 placed in the closed position on a valve seat 23 under the action of a compression spring 25, and an outlet 13 which is in communication with the atmosphere.
- the spring 25 bears, at one of its ends, on the valve 21 and, at its other end, on the bottom 27 of an adjusting nut 29 in the shape of a bell which is screwed on a thread 31 of the body 17.
- the inlet 19 of the mechanically controlled valve 11 is connected to the outlet 3 of the compressor 1 and to the inlet E 2 of the injector 5 via the pipe 3.
- the stiffness of the spring 25 is chosen so that after adjustment of the compression thereof by means of the nut 29, the valve 21 is pushed back by the pressure of the incident air, against the pressure force of the spring 25 as soon as the permissible pressure exceeds the value of the desired operating pressure Fu as pressure at the inlet of the injector, or set pressure, namely in the present embodiment of the invention a value of 3.10 5 Pa. admitted then exits outwards through the outlet 13, so that a leak is created and this until the pressure drops back to its nominal value P, the valve 21 then returning to its position of contact with its seat 23.
- the present device thus makes it possible to regulate the pressure of the air admitted into the injector 5 and this without resorting to a storage tank, which besides the problems of cost, size and weight is otherwise the source of difficulties and various disorders encountered in decontamination devices of the prior art and which have been mentioned above.
- the microcontroller 42 would be programmed so as to constantly compare the value of the actual pressure existing in line 3 with the value of the set pressure J 2. As soon as the pressure in the pipe 3 exceeds this setpoint pressure value, the microcontroller 42 would control the opening of the valve 44, and this opening would be greater the greater the pressure difference.
