Description

A SEPARATOR FOR AND HEAVIER RESEARCH ESTABLISHMENT 2 consists in separators for the separation of liquid or gaseous aerosols and for into eomponen of different specific comprising a series of nozzles disposed at a distance from each other along a path along which the fluid mixture can be each nozzle feeing so designed at fluid inlet side that it collects preferentially the specifically eomponent of the fluid mixture the specifically lighter eomponent is deflected out of said the nozzles feeing disposed on a support designed to fee rotated at a high the first nozzle to receive the fluid mixture being the one nearest to the axis of the support and each following nozzle being remoter from that axis than the preceding By a particularly advantageous embodiment of the invention the nozzles are annular and concentric in relation to the axis of the disc in a plane perpendicular to this She annular nozzles may consist each of two rings whose inlet ends taper to form sharp edges while their surfaces which face each other across the annular slot constituting the nozzle opening are flat and An embodiment of the invention is by way of example in accompanying drawing in 1 is a fragmentary axial section of a separator according to the 2 is a fragmentary perspective view of a detail The here illustrated a hub 2 mounted on a shaft 1 and carrying four 6 superposed upon one another with distances between which are determined by washers The space between the two inner discs 5 forms the path for the fluid mixture to be separated into its and within this space there is disposed a set of annular nozzles 8 formed each by two rings 10 Each of these rings is bevelled on its inner side whereby sharp edges 12 with outer bevel faces 20 are formed at the inlet side of each The mutually faoing surfaces of the two rings 10 form a narrow ring slot A which may have a width for 1 7 depending on the nature of the fluid mixture to be separated into its may have any other suitable 20 and The discs 4 and 5 have passages 13 in the region of the nozzles through which the spaces adjacent the bevel faces 20 of the nozzles are connected with the discharge spaces 15 enclosed between discs 3 and 4 and discs 5 and The hub 2 also carries a funnel 16 which extends through discs 6 and 5 into the space between and 4 where its flanged 17 together with washer the first nozzle The shaft 1 is designed to be rotated at high According to the fluid mixture to be separated rotary speeds from to rpm may be but in special cases the speed may be as high as rpm 4 and shaft 1 joumalled in i which compressed air flows or into an annular space which connected with the atmosphere through narrow annular slots ound the compressed air passing through these narrow air slots prevents direct contact between the shaft and axial is provided with a supply of compressed Compressed air flows out o the bearing between the end of one of the radial bearings and a disc mounted on sha keeps the disc spaced from the ront end of the separator operates as the fluid mixture to be separated is supplied continuously to the 16 where it a revolving motion and om which it is driven by centrifugal force through the annular formed between the parts 17 in the form of annular When this emerges from the nosale it disperses and separates into a heavier core and a lighter core enters between the edges 11 and 12 of the second 8 and is through the rings 9 and 10 of that fhe jacket is led away along the surfaces 19 and 20 of the second nozzle and passes through the openings 13 into the collecting spaces stream emerging that nozzle 8 is similarly divided into a core and a and the process is thus repeated until and the outermost nosszle the Bach time is the core of specifically heavier components that passes on to the next noaale while the jacket of specifically lighter is drained stream leaving the last nozzle 21 contains a high proportion of the specifically heavy mixture while the proportion of these heavier in the drained jackets drops from nozzle to At the edges of the discs the separated components of the mixture from slots 22 and the outer ends of spaces and from the last nozzles 21 of the set of nozzles and are collected The in the embodiment are annular disposed in concentric a aeries of discrete may he disposed on a line running from a point near the center of the from the region of the innermost nozzle 8 in towards the periphery of the instead of being designed as separate elements the nozzles can be made each integrally with the corresponding disc in the case of concentric nozzles as illustrated in the the nozzles can be disposed in alternation on either of the two discs and the latter be rotated oppositely relative to one this manner the tangential components of the motion imparted to the mixture on its passage through the nozzles change directions from nozzle to nozzle and thus cancel each other so that the fluid passes in a substantially radial direction through the insufficientOCRQuality

Claims (1)

1. 6 A separator for the separation of liquid or aerosols or the into components of different specific comprising a series of nozzles disposed at a distance from other along a path along which the fluid mixture can be each nozzle being so designed at its fluid inlet side that oollects preferentially the specifically heavier component of the fluid mixture while the specifically lighter component is deflected out of said the nozzles being disposed on a support designed to rotated at a high the first nozzle to receive the fluid mixture being the one nearest to the axis of the support and each following nozzle being remoter from that axis than the preceding A separator according to Claim wherein the nozzles are arranged in circles concentric with the axis rotation of the A according to Claim wherein each nozzle aperture is an annular slot extending in a plane perpendicular to the axis of rotation of the A separator according to Claim in which each nozzle consists of two rings and the edge of each ring on the inlet side of the nozzle is bevelled and forms a sharp edge while the sides of the ring facing each other across i the slot are flat and A separator according to Claim wherein the slot has a width of 1 1 7 A separator according to any of 1 to wherei the nozzles are mounted between rotary which have passages for draining off the specifically lighter outer part of the jet which emerges from the preoeding and is deflected by the outer surfaces of the inlet of the following A separator according to Claim wherein the passages in the discs open into spaces delimited by latter discs and by further and an annular draining slot is formed at the periphery of each such A separator according to any of 1 to wherein the supports carrying the nozzles are designed to be rotated at a speed of to preferably from to A separator according to Claim wherein the nozzle supports are mounted on a sha in axial and radial air A modification of the separator according to any of Claims 1 to wherein disere oblong nozzles are disposed along a spiral line beginning near the center of the support and extending towards the periphery of the A separator according to any of Claims 1 to wherein the nozzles are disposed in alternation on either of two supports disposed to be in opposite A separator for separating fluid tially as herein described and illustrated the accompanying For the Applicants PARKERS insufficientOCRQuality
