Internal combustion engines, such as diesels and gas turbines, require substantial amounts of clean air to operate efficiently. Such engines normally utilize filtertype air cleaners to clean ambient, dirt ladened air prior to its discharge into the engine. In addition to the air cleaners, many engines further utilize a fan for aiding in the removal of dirt. Such conventional air cleaning systems are oftentimes costly, bulky and tend to induce pressure and velocity fluctuations which induce an inefficient discharge of the air into the engine.
SUMMARY OF THE INVENTION An object of this invention is to overcome the above, briefly described problems by providing a non-complex and economical inertia type air cleaner which assures an efficient discharge of clean air into an engine and which requires minimal servicing.
The air cleaner comprises an annular housing defining an inlet and an outlet and an annular member attached within the housing. A plurality of circumferentially spaced vanes are secured to the member, adjacent to the housings inlet, to extend radially outwardly to define a plurality of first passages for centrifugally expelling incoming ambient air therefrom. A second passage, defined between the member and the housing, extends radially inwardly to communicate clean air to the compressor stage of a gas turbine, for example. A third, restricted passage is positioned radially outwardly from the second passage to communicate with the first passage to receive contaminants, such as dirt, centrifugally discharged therein.
BRIEF DESCRIPTION OF THE DRAWINGS Further objects of this invention will become apparent from the following description and accompanying drawings wherein:
FIG. 1 is a longitudinal cross sectional view of a portion of a gas turbine having the inertial-type air cleaner of this' invention attached to the compressor stage thereof;
FIG. 2 is an enlarged view of the air cleaner, taken in the direction of arrows Il--II in FIG. 3;
FIG. 3 is an end elevational view of the air cleaner, taken in the direction of arrows III-III in FIG. 2;
FIG. 4 is a cross sectional view taken in the direction of arrows IVIV in FIG. 2; and
FIGS. 5-7 are enlarged sectional views respectively taken in the direction of arrows V-V, Vl-Vl and VII- VII in FIG. 4.
DETAILED DESCRIPTION The conventional turbine, partially illustrated in FIG. 1, has an axial-centrifugal compressor adapted to discharge air into diffuser ducts 11 and combustion chambers 12. The turbine functions in a conventional manner to discharge heated and expanded gases through nozzle vanes 13 and against the blades of a gas producer turbine wheel 14. Such gases further drive a power turbine (not shown) which in turn drives a power output shaft.
This invention is drawn to an inertial-type air cleaner 15 adapted to have an annular, plastic housing 16 thereof attached to the turbines compressor stage to supply substantially clean air to a co-axially aligned inlet thereof. Referring to FIGS. 2 and 3, the air cleaner is disposed on a longitudinal axis X thereof and further comprises an annular inlet 17 and an axially spaced annular outlet 18 communicating with the compressorinlet. An annular plastic member 19, having aerodynamically shaped front and rear cones, is attached within the housing between inlet I7 and outlet 18 by plastic vane means 20.
The vane means comprises a plurality of circumferentially and equally spaced vanes 21 positioned adjacent to inlet 17 to define a plurality of first passage means between each adjacent pair of vanes for centrifugally expelling air radially outwardly therefrom. A semi-spherically shaped screen 22 (FIG. 2) is attached at the inlet to housing 16 to prevent the ingress of large particles of dirt and the like therethrough. As shown in FIG. 3, the vanes are preferably equally spaced about axis X and are disposed in parallel relationship therewith.
When viewed in such transverse cross section (FIG. 3), each vane has compound radii of curvatures which gradually decrease in magnitude, substantially along the full length thereof, from axis X radially outwardly towards housing 16. In addition, a radial inner portion 23 of each vane is disposed in approximate tangential relationship and closely adjacent to the axis, whereas a radial outer portion 24 thereof is disposed in approximate tangential relationship relative to circular inner wall portions 25 of housing I6. Also, each pair of circumferentially adjacent vanes generally diverge radially outwardly from the axis. As viewed in cross section along axis X in FIG. 2, the first end of each first passage means, positioned at inlet 17, has a substantially larger cross sectional area than a second end thereof, positioned at a communicating second passage means 26. The first passage means are designed to provide a substantially uniform air velocity therethrough. The annular second passage means, defined between member 19 and housing 116, extends radially inwardly towards axis X to communicate substantially clean air from the first passage means to outlet 18.
A third passage means 27, defined in the housing, has an annular inlet 28 disposed in approximate parallel relationship with respect to axis X and positioned radially outwardly from second passage means 26. Inlet 28 preferably has a cross sectional area which is substantially less than that of each of the first and second passage means. The third passage means further comprises a radially inwardly extending portion 29 communicating with a contaminant collecting means comprising a collecting chamber 30.
Referring to FIGS. 4-7, eccentrically disposed inner and outer wall portions 31 and 32, respectively, are formed on the housing to define the generally annular collecting chamber. When revolved about axis X, the chamber has a gradually enlarged cross sectional area from an upper portion to a diametrically opposed lower portion thereof. The collecting means further comprises a collecting box 33 (FIG. 2) secured to housing 16 to have a chamber thereof communicate with the lower portion of the annular collecting chamber.
The above described air cleaner is designed to remove approximately 95 percent of the incoming dirt particles and other contaminants, down to a 3 to 5 micron size. During a typical air-cleaning operation: Approximately llO percent of the air required for efficient turbine operation flows through inlet 17 at approximately 60fps; the air increases to a velocity approximating 85fps in the first passage means defined by vanes 21; air entering second passage means 26 attains a velocity approximating l40fps which increases to about 360fps at outlet 18; approximately percent of the total air inflow enters inlet 28 of the third passage means and carries the inertially separated dirt particles to collecting box 33 whereat a compressor discharge pressure or exhaust gas driven jet pump (not shown) functions to pick them up at an outlet 34 and discharges them to ambient.
