Definitions
- the present invention relates to a device for sampling gaseous substances, liquids, aerosols or even pulverulent materials, for their analysis in situ in a device for analyzing gaseous compositions.
- It relates in particular, but not exclusively, to the detection of contamination by very high toxicity substances such as those which are used in chemical weapons and which can be spread in the form of gas, fine droplets or even fine spaced particles each other.
- the sampling device comprises: a flexible tongue carrying a heating resistance electric used to vaporize the substances collected by the tongue.
- this device necessarily requires the intervention of an operator: He must take the samples and then proceed to vaporize the liquid substances sampled, so that the vapors produced are sucked by the analysis device as a gas composition to be analyzed.
- the invention more particularly aims to achieve these results without the help of any operator so as to be able to use the whole sampling device / analysis device in the manner of an autonomous probe placed on a site. to be able to instantly detect the presence of contamination or air pollution.
- the sampling device comprises a collector having a collecting surface exposed to the atmosphere of which it is desired to detect any contamination, a sampling member coming into contact with said collecting surface, on a zone of reduced dimensions, means making it possible to effect relative movement between said sampling member and said surface, so that the latter is scanned by said sampling member, during at least one scanning sequence, means heating associated with said sampling means for carrying out a vaporization of the contaminating materials possibly collected during the scanning sequence and a suction nozzle intended to be connected to the intake orifice of a composition analysis apparatus gaseous, this nozzle being shaped so as to be able to suck the vapors of contaminating materials produced uites by means of heating.
- the above-mentioned suction nozzle may include a register making it possible to carry out:
- sampling device may include an automatic mechanism allowing the heating means and the analysis apparatus to be implemented at the end of the scanning sequence.
- Figure 1 is a side elevational view of a gas composition analysis apparatus equipped with a sampling device according to the invention
- Figure 2 is an elevational view, on a larger scale, of the sampling device shown in Figure 1;
- Figure 3 is a partial sectional view of the sampling member and the suction nozzle associated therewith;
- Figure 4 is an axial sectional view of the manifold.
- the gas composition analysis apparatus consists of a portable and autonomous apparatus for analysis by flame spectrophotometry of the type which is described in patent FR No. 87 02762 in the name of the Applicant.
- This device comprises a body 1 of elongated shape having, on one side, electrical connection means 2 and, on the other side, a suction head 3 of the gases to be analyzed. Its grip is ensured by a handle 4 enclosing a generator delivering the hydrogen which takes part in the combustion of the gas to be analyzed in order to produce the flame of which the spectrographic analysis is carried out.
- This device involves a burner provided with a window equipped with a focusing optic in the axis of which are arranged a rotary chopper comprising a plurality of optical filters each corresponding to a desired element, and an optoelectronic cell placed in the area of focusing of optics.
- the electrical signal delivered by the cell is transmitted to an electronic processing circuit making it possible to determine and display on a display the content of the gas in sought-after components.
- an electronic processing circuit making it possible to determine and display on a display the content of the gas in sought-after components.
- it comprises means making it possible to trigger an alert and, optionally, to transmit an alarm signal remotely following the detection of a sought-after component.
- the intake of the gas to be analyzed (usually ambient air) inside the burner is ensured by means of a turbine and an intake duct which opens out through an orifice 5 made in the head suction 3.
- the removable sampling device 6 associated with the analysis device 1 is designed so as to be assembled, using assembly and fixing means that can be easily disconnected on the suction head 3 of the device.
- a manifold 7 comprising a housing of substantially cylindrical-frustoconical shape, the base 8 which closes the cylindrical part 9, extends obliquely with respect to the general axis of symmetry XX '.
- an assembly part 10 in the form of an angle iron, one of the wings of which is provided with a recess 11 in which passes a nozzle 12 intended to engage in the orifice 5 of the head suction 3.
- the manifold housing 7 contains a coaxial electric motor 15, the output shaft 20 of which passes through the small base constituting the top of the frustoconical part.
- This motor 15 is supplied with electrical energy by the analysis apparatus 1, by means of a cable which is connected to the electrical connection means 2. -
- the shaft 20 drives in rotation, thanks to a key 21, a drive part, of substantially conical shape 22 which extends parallel and at a short distance from the frustoconical part 18.
- the dynamic sealing between these two parts is then ensured by the use of an O-ring 23 of X-shaped section.
- a coaxial collecting cap 24 On the drive piece 22 can be disposed a coaxial collecting cap 24 whose conical convex outer face constitutes the collecting surface which is intended to be exposed to the atmosphere whose contamination is to be measured. Furthermore, this collecting cap 24 comprises, along one of its generatrices, a groove 25 whose role will be explained below.
- a fixing part 26 On the cylindrical lateral face 9 of the housing is fixed by screwing a fixing part 26 having a through hole 27 axially parallel to the axis XX 'of the housing and opening into a region located opposite the suction head 3, when the sampling device 7 is in the assembled position on the analysis apparatus 1.
- This collector / evaporator 29 comprises a sampling and heating ramp 30 mounted at the upper end of the section 28 and comprising, inside a support 31 in the form of a gutter, a brush 32 intended to come to bear on the collecting surface of the cap 24, substantially over the entire length of its generatrix.
- the support 31 and the brush 32 are oriented so that, when the section 28 is fully engaged in the bore 27, the support 31 defines with the collecting surface, a channel in communication with the interior volume of the section 28 and that the brush 32 comes to apply on said surface, to retain the polluted elements which may have been deposited there.
- the brush 32 is in the form of a flexible tongue possibly covered with an absorbent layer, and carrying an electric heating resistance.
- This electrical resistance is supplied by the electrical energy source of the analysis apparatus 1 and is controlled by a switch when the brush 32 is facing the groove 25.
- the lower end of the sleeve 28 is tightly connected to the suction head 5 of the device 1 by means of a T-shaped connecting element, 33.
- the apparatus 1 sucks in an air flow which successively circulates in the ramp 30, in the section 28 and in the connector 33.
- the assembly constituted by the sampling device 6 mounted on the portable analysis device 1 is placed on the site that we want to monitor, the axis of the motor 15 and of the collecting cap 24 being oriented vertically.
- the cap has its convexity oriented upwards so as to be exposed to contamination by the elements sought. This contamination can consist, for example, of a mist of fine droplets suspended in the air.
- the switching on of the device 1 controls the execution of a succession of operating cycles each comprising:
- a heating phase of the brush 32 so as to vaporize the polluting or toxic materials which have possibly been deposited on the collecting surface and which have been collected by the brush during the rotation of the cap 24, - simultaneously with the heating phase, an analysis sequence during which the analysis device 1 sucks the gaseous atmosphere contained in the sampling ramp 30, via the sleeve 28 and the connector 33 and proceeds to spectrophotometric analysis of this gaseous atmosphere (possibly charged with vapors of polluting or toxic materials collected).
- the device 1 triggers an alert signal, for example light and / or sound, and possibly the transmission of an alarm message, for example over the air. .
- the operating cycles can succeed one another continuously or discontinuously, according to a predetermined periodicity, possibly adjustable.
- cap 24 of conical shape, has the advantage of allowing the flow of water, in the event of rain, as well as solid particles brought by the wind which could alter the functioning of device 1.
- the groove 25 provided in the cap 24 has, for its part, the following advantages. In particular, it allows:
- the tubular sleeve 28 and / or the connecting element 33 may be equipped with a register making it possible to connect the suction head 3 directly to the atmosphere, without passing through the ramp 30, so as to be able to alternate analysis phases, the gaseous composition of the ambient air and phases of detection of the presence of contaminating substances in liquid or solid form suspended in the air.
- the collecting surface could have a shape different from that of a conical cap: it could for example be flat and animated by a continuous translational movement (unwinding of a film) or alternating. It could possibly be cylindrical and be arranged coaxially with the suction head.
- the brush 32 can be designed so as to be able to selectively absorb and therefore concentrate the products which it is desired to highlight. It may for example be coated with a silica gel deposited on the surface and held by silicone, and be formed by the juxtaposition of several tongue elements.
