Abstract
Abstract A method and apparatus are disclosed for separating particulates from hot gas in the type of system employing a particulate gas chamber, a clean gas outlet chamber and an array of separator units. The structure defining the clean gas chamber is suspended solely from a top cover of a housing thus avoiding serious heat differential problems. The separator units are provided with a novel inlet to enhance separation efficiency, and a method is provided for increasing bypass of particulate past the separator units without adversely affecting the operation thereof. <IMAGE>

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
125 words
Apparatus for separating particulate material from hot gas, comprising: a housing having a transversely extending top cover portion, conduit means communicating with the exterior of said housing and serving to conduct particulate laden hot gas to a particulate laden hot gas chamber within said housing, a clean gas receiving chamber suspended in load bearing relation solely from the top cover portion of said housing and serving to emit cleaned gas upwardly to the housing exterior, a particle discharge chamber disposed between said housing and said particulate laden gas chamber, and a plurality of separator units disposed transversely through said particulate laden gas chamber for separating particles from gas, discharging the gas into said clean gas chamber and discharging the particles into said particle discharge chamber.
Claim 2
Dependent Claim
26 words
The apparatus of claim 1 in which said transversely extending top cover portion of the housing is in the form of an upwardly extending arc structure.
Claim 3
Dependent Claim
25 words
The apparatus of claim 1 in which said conduit means comprises a pair of conduits connected diametrically on opposite sides of said top cover portion.
Claim 4
Dependent Claim
42 words
The apparatus of claim 3 in which said pair of conduits are disposed equidistantly from a central portion of said top cover portion, and said clean gas is emitted through an outlet conduit positioned at said central portion of the top cover.
Claim 5
Dependent Claim
63 words
The apparatus of claim 1 in which said particulate laden hot gas chamber is defined by an exterior wall of a clean gas structure enclosing said clean gas chamber and by an interior wall of a particulate laden hot gas subhousing, an exterior wall of said latter subhousing serving together with the wall of the main housing to define a particle receiving chamber.
Claim 6
Dependent Claim
115 words
In an apparatus for separating particulate material from hot gas comprising a housing, conduit means communicating with the exterior of said housing and serving to conduct particulate laden hot gas to a particulate laden gas chamber within said housing, a clean gas receiving chamber serving to emit cleaned gas to the housing exterior, a particulate discharge member serving to emit particulates from the exterior of said housing and separator means adapted to receive particulate laden hot gas and discharge clean gas to said clean gas receiving chamber and particulate to said particulate discharge chamber, the improvement comprising a converging inlet member on said separator means for accelerating the particulate laden gas within the separator means.
Claim 7
Dependent Claim
35 words
The apparatus of claim 1 in which said housing extends along a vertical axis and said conduit means introduces said particulate laden hot gas into said particulate laden hot gas chamber in an axial direction.
Claim 8
Dependent Claim
32 words
The apparatus of claim 7 in which the separator units have an inlet in the form of a convergent structure, the inlet orifice of which is substantially parallel to said vertical axis.
Claim 9
Dependent Claim
32 words
The apparatus of claim 6 in which said separator units each comprise a cylindrical shell, and said converging inlet member is mounted on a portion of said shell and extends exteriorly thereof.
Claim 10
Dependent Claim
21 words
The apparatus of claim 6 in which the inlet opening of said converging inlet member is positioned in a vertical plane.
Claim 11
Dependent Claim
28 words
The apparatus of claim 8 in which said separator units each comprise a cylindrical shell, and said convergent inlet structure is positioned on a portion of said shell.
Claim 12
Dependent Claim
30 words
The apparatus of claim 11 in which the convergent inlet member communicates tangentially with said separator means for delivering said particulate laden hot gas tangentially to an interior wall thereof.
Claim 13
Dependent Claim
45 words
The apparatus of claim 6 in which the convergent inlet member comprises a converging box-like structure the interior of which is insulated on at least three sides, and the edge of said insulation adjacent the inlet is bevelled or rounded to minimize wear and deterioration.
Claim 14
Independent Claim
138 words
A method of enhancing the efficiency of a cyclone separator of the type having particulate laden hot gas led axially through a separation chamber to a particulate outlet, and an array of separator units communicating with said separation chamber and with a clean gas chamber in which the gas is led in the opposite axial direction to a clean gas outlet, which comprises disposing inlet orifices for said units in planes substantially parallel to said axial flow of the particulate laden gas with provision for introducing the particulate laden gas to each unit in a direction transverse to said axial flow, and accelerating the particulate laden gas as it proceeds in said transverse direction, whereby an increase in the quantity of particulate material passing through said particulate outlet is achieved without impairing the efficiency of the separator unit.
Claim 15
Dependent Claim
32 words
A method according to claim 14 in which the gas entering each separator at its orifice is given circular motion in a converging region leading to the interior of said separator unit.
Claim 16
Dependent Claim
41 words
A method according to claim 15 in which the interior of said separator unit is cylindrical, and the circular motion imparted to the particulate laden gas causes its motion to progress along the outer periphery of the interior of the cylinder.
