Definitions
- the present invention relates to dust separators and more particularly to dust separators of the type comprising a plurality of cyclones arranged in stepped fashion one above the other the tangential inlets of said cyclones communicating with a common inlet channel for the dust-laden gas and the axial outlets thereof cornmunicating with a common outlet channel for the purilied gas separate from the inlet channel.
- the object of this invention is to eliminate said disadvantages and above all to provide a dust separator of the above type, which has a very compact construction.
- the inlets of the cyclones are formed with obliquely cut-olf connection pieces extending through the stepped casing wall and so disposed that the mouths of the connection pieces lie in one single plane coincident with that of the corners of the stepped wall directed towards the interior of the casing.
- Figure l shows a perspective view with parts broken away of a dust separator embodying the principles of the invention
- Figure 2 is a similar view on an enlarged scale illustrating a part of the dust separator of Figure l;
- Figures 3 and 4 show an element of the stepped wall of the casing in front and side view respectively;
- Figure 5 illustrates a modified arrangement in vertical cross-section.
- the numeral 1 denotes a 2,854,092 Patented Sept. 3f), 1958 number of cyclones arranged in rows and in stepped fashion one row above the other, there being four rows each comprising four cyclones shown in the embodiment illustrated.
- the cyclones 1 are arranged on the outside of and connected to a casing 2 having walls at right angles, one such wall 3 having a stepped appearance conforming to the stepped disposition of the cyclones.
- the tangential inlets 4 of the cyclones are arranged at the portions of the stepped wall which are parallel to the axes of the cyclones, while the outlets 5 of the cyclones are arranged .in wall portions extending at right angles thereto.
- the casing is divided by a. rst partition 6 into an inlet channel 7 for the dust-laden gas entering by the inlet end 8 of the casing 2 and an outlet channel 9 for the purilied gas discharged from the outlets 5 -of the cyclones.
- the partition 6, which is formed by a plate extending lacross the width of the casing, as seen from Figures l and 2, extends from the stepped wall 3 vat the main inlet S of the casing 2 to the opposite wall adjacent the main outlet 10 of the casing.
- the plate has longitudinal slots defining recesses opposite to the inlets 4 of the cyclones, said slots having lateral wall portions 12 extending towards the cyclone inlets 4, said lateral walls being adapted to be connected to inlet connection pieces 13 of the inlets 4.
- the width of the slots is such that each rslot may be connected to the inlet connection pieces of two adjacent cyclo-nes, as seen from the drawing.
- the inlet channel 7 dened by the partition 6 the ⁇ slots and the lateral walls 12 is closed at its upper end by a .second partition wall or plate 14 connecting the respective lateral walls 12, whereby the dust-laden gas supplied through the inlet end 8 of the casing 2 is compelled to pass .into the inlets liand through the cyclones 1 which are .connected to the inlet .channel .'7 by the connection pieces 13.
- the stepped wall may be .constructed from angular, preferably right-angled wall elements 15 ( Figures 3 and 4) in a number corresponding to that of the rows of cyclones, one ange 16 of said wall elements forming the end-walls of the cyclones in the associate row of cyclones and also the lower walls of the inlet connection pieces 13.
- the mouths of the connection pieces are cut ofr" obliquely so that they lie in a single plane 17 coincident with the free edges of the flanges 16 and flanges 18. Thereby the tree edges of lateral walls 12 will lie along a straight line and are readily joined t-o the inlet connection pieces 13.
- the cyclones are further connected to a dust discharge conduit 19.
- FIG. 5 illustrates a pair of identical dust separators of the type hereinbefore described, secured together along adjacent edges of the respective partitions and ducts, whereby both of the separators discharge through a common outlet 10. Otherwise, each of the two units is identical to that hereinbefore described and the reference numerals refer to corresponding structure.
- a dust separator of the type comprising a plurality of cyclones arranged in a stepped fashion one above the other, said cyclones having tangential inlets communicating with a common inlet channel for the dust laden gas and axial outlets communicating with a common separate outlet channel for the purified gas, a common casing open at opposite sides to form a main inlet and a main outlet, the walls of said casing being disposed at right angles, one of the walls being stepped, irst partition walls within said casing extending longitudinally at a right angle to the stepped casing wall from the inlet side to the outlet side of the casing to form several longitudinal channels within the casing in side-by-side arrangement, and second partition walls within said casing closing at least one of said longitudinal channels on the outlet side of the casing, the other end of said one channel being open on the inlet side of the casing and further communicating only with the inlets of said stepped
- a dust separator as claimed in claim l in which the inlets of the cyclones are formed with obliquely cut-oli inlet connection pieces extending through the stepped Wall and so disposed that the mouths of the connection pieces lie in a single plane coinciding with that of the inwardly directed corners of the wall.
- a dust separator as claimed in claim 2 in which the inlet connection pieces extend through parts of the stepped wall lying parallel to the cyclone axes said parts having a width substantially equal to the extension of the inlet connection pieces in the same direction, while the other parts of the stepped wall have a Width corresponding to the major diameter of the cyclones.
- a dust separator as claimed in claim 3 in which those parts of the stepped wall which are at right angles to the axes of the cyclones form the end Walls of the cyclones and the lower walls of the inlet connection pieces.
- a dust separator as claimed in claim l in which the inlets of the cyclones are formed with obliquely cut off inlet connection pieces extending through the stepped wall, in which the first partition Walls dividing the casing into inlet and outlet channels are formed by a plate extending from the stepped wall at the inlet end to the opposite wall adjacent the outlet end, said partition walls having slotsl defining recesses opposite to the oblique inlet connection pieces of the cyclones, and in which lateral walls extend from the edges of the partition walls defining said slots towards the connection pieces and are joined thereto.
