Definitions

  • the present invention relates to a mobile separator thermal separator.
  • Thermal separators are devices operating on pulsed gas flows and taking advantage of the physical phenomena which result therefrom to subdivide an initial stream of compressed gas having a certain temperature into a first lower temperature flow and a second higher temperature flow rate, this latter flow rate being able to be low or even zero, so that the appliance can ultimately behave like a gas cooler.
  • the present invention relates more specifically to devices of the latter type, that is to say of the mobile injector-distributor type, which are particularly - although not exclusively - suitable for treating low gas flow rates.
  • thermal separators known at present, operating with a rotary injector and generally operating with significant flow rates, the gas under high pressure is injected radially, from the center to the periphery, into a bundle of radiating receiving tubes distributed over a crown or star-shaped.
  • the injector will be small and therefore the leakage to the correct injector, but the receiving tubes will necessarily have a very small diameter, which is difficult to achieve and affects performance (because of the fluid friction) unless you turn quickly.
  • the permanent leak at the inlet of the rotating injector is appreciable.
  • the subject of the present invention is a thermal separator with a mobile distributor as characterized in the claims, which makes it possible to achieve all of these objectives, even when operating on low gas flow rates, by virtue of a characteristic arrangement which consists in reversing the directions of propagation of the fluid: the high pressure gas always enters radially (or at a small angle), but in the direction going from the outside towards the inside of the device, which makes it possible to join several receiver channels very easily in one only. Between the rotating part (receiver channels coming together) and the rest of the fixed receiver tubes (after several channels have been combined), there is always a leak (as for the injector of current devices), but it is negligible during the periods when the receiver tube is draining (approximately 70% of the time). In addition, the entry of each elementary channel being able to be a rectangular slit (easy to carry out), one “will open quickly on rather wide receiving tubes (meeting of several elementary tubes), with moderate leaks.
  • the fixed housing 1 of the device is a hollow cylinder comprising two opposite rectangular openings 2, 2 for opening with high pressure HP gas and two opposite rectangular openings 3, 3 for opening with expanded gas LP, located to the right of the previous ones but offset 90 ° to them.
  • Inside this fixed cylinder 1 rotates an essentially full cylindrical plug 4 in which two elementary channels 5, 5 are made, starting at the periphery by a thin rectangular longitudinal slot 6, 6 and meeting at the center to form a square 7. This meeting evolves along the axis by a transformation from square to round and the terminal circular section 8 comes to rotate just opposite a large coaxial receiving tube 9 and of the same section.
  • the general direction of the high pressure gas goes from the outside (in 6) towards the inside (in 7-8 ).
  • the feeding phases are limited to the time during which the slots 6, 6 remain, in their rotary scrolling movement, facing the HP lights 2, 2 - while the major part of a revolution, that is to say around 70%, corresponds to the running of the slots 6, 6 over the circumferential extent of the lights BP 3, 3 and of the solid sectors 11 - this reduces the duration and therefore the extent of the gas leak which can occur at the level of the functional clearance existing between the central outlet 8 of the elementary channels 5, 5 and the adjacent end of the receiving tube 9, the leakage being negligible during periods of non-supply of the receiving tube 9.
  • peripheral slots 6, 6 being longitudinal and thin, the "laminating transitions are extremely brief and certainly insignificant between the complete closure (slots 6 facing the solid sectors 11 of the wall of the housing 1) and full opening at full section (slots 6 opposite the lights 2 or 3), when the plug 4 rotates, without it being necessary to turn at high speeds.
  • FIGS. 5 and 6 differs essentially from the previous embodiment in that the plug 4 comprises elementary channels 5, 5 which begin with orifices 12, 12 oriented parallel to the axis and passing in front of HP lights 13, 13 and BP (not shown) also axial and distributed along a circle on the bottom 14 of the housing 1.
  • FIG. 11 shows two conjugate elementary channels 5D, 5E originating in slits peripherals 6, 6 diametrically opposite and opening, through axial openings 8, 8 at opposite ends of the plug 4, in receiving tubes 9A, 9B such as those of FIG. 7. It is clearly seen in FIG. 11 that the elementary channels 5D , 5E have reverse bends.
  • the slide 15 is formed from a thin-walled tube very largely indented in two intermediate zones separating three continuous tubular sections: a first end section 16 extending between ends A and B, a median section 17 extending between ends C and D and a second end section 18 extending between ends E and F.
  • These successive tubular sections 16-17-18 are joined by longitudinal bars 19 which on the one hand they join together to make the drawer 15 a one-piece piece in the form of a perforated hollow cylinder and which on the other hand form between them large notches 20 and 21 extending respectively between the ends BC and the ends DE .
  • a transverse partition 22 Inside the median tubular section 17 is fixed a transverse partition 22 whose role and details will appear in the following.
  • the drawer 15 thus designed slides in a fixed sheath 23 to which one or more pulsating receiving tubes are connected (not shown on the demki, but which may be located in the extension of the sheath 23 on one or both sides).
  • a fixed sheath 23 Through the wall of this fixed sheath 23 are practiced lights at three levels extending along the axis: a first set of lateral gas inlet lights HP 24 extending axially between edges G and H; a set of median gas outlet lights BP 25 extend axially between edges 1 and J; a second set of lateral gas inlet lights HP 26 extending axially between edges K and L.
  • the sliding drawer has been fitted with an air spring which, in the embodiment illustrated in FIG. 13, consists of a piston 27 integral with the partition 22 and movable in a cylinder 28 , the opposite faces of the piston 27 delimiting with the bottoms facing the cylinder 28 two sealed compartments 29-30 with variable volumes in opposite directions: when the drawer 15 moves to the left of the drawing - and consequently the piston 27 also since it is an integral part of it - the gas filling the compartment 29 is compressed while the gas filling the compartment 30 expands.
  • the opposite phenomena occur when moving to the right of the drawer 15 and its piston 27: the compartment 29 expands while the compartment 30 compresses, reversing the direction of the resulting force exerted on the piston 27.
  • the peripheral element 32 of the fixed body 31 comprises, in its transverse median part, HP gas inlet ports 39 and, in its center, on either side of the sliding body 37, a first gas outlet opening BP 40 and a second BP gas outlet opening 41.
  • the central core 35 of this fixed body 31 is hollowed out and has channels 42 which begin with orifices 43 located at the right of the HP inlet lights 39 and which terminate jointly in a common channel 44, which can itself be a pulsating separator tube or else connect to it.
  • the sliding body 37 has radial channels 45 which can, in one position (that which is illustrated), put the channels 42 in communication with the HP inlet lights 39 and, in another position away from the previous on one side or the other, put these channels 42 to drain either by the BP outlet 40 (sliding body 37 shifted to the right), or by the BP outlet 41 (sliding body 37 shifted to the left).
  • the exciting force of the reciprocating movement of the drawer 37 comes from the fact that, when the latter approaches a end and puts the tube 44 to the drain by 40 or 41 as the case may be, the LP gas which leaves the orifices 43 must "take the bend to escape, which provides an impulse in the direction of the movement because the gas flow comes strike the corresponding face of the movable drawer 37 and is deflected by it towards the outlet 40 or 41.
