Abstract
Abstract A cyclone separator assembly includes a conveying pipe for conveying a carrier gas and solids conveyed thereby along a flow path extending in a rectilinear direction. A diagonal wall extends across the conveying pipe in a direction which is diagonally inclined with respect to the rectilinear direction. A plurality of cyclone separator units are located adjacent the diagonal wall. A plurality of branch pipes, one each for each cyclone separator unit, convey carrier gas and solids from the conveying pipe to the cyclone separator units. Each branch pipe has a first end connected to the diagonal wall and a second end connected to a respective cyclone separator unit. At least an initial length portion of each branch pipe, taken from the first end thereof, extends in a direction substantially parallel to the rectilinear direction of flow of the carrier gas and suspended solids within the conveying pipe.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
227 words
A cyclone separator assembly for use in separating solids such as coal from a carrier gas conveying such solids, said assembly comprising: conveying pipe means for conveying a carrier gas and solids conveyed thereby along a flow path extending in a rectilinear direction; a diagonal wall extending across said conveying pipe means in a direction which is diagonally inclined with respect to said rectilinear direction; a plurality of cyclone separators located adjacent said diagonal wall; and branching pipe means for transferring said carrier gas and solids from said conveying pipe means to said cyclone separators, whereat said solids and carrier gas are separated, said branching pipe means comprising a plurality of branch pipes, one said branch pipe for each said cyclone separator, each said branch pipe having a first end connected to said diagonal wall and opening into said conveying pipe means and a second end connected to and opening into a respective said cyclone separator, at least an initial length portion of each said branch pipe, taken from said first end thereof, extending in a direction substantially parallel to said rectilinear direction, such that said solids and carrier gas, upon passing said diagonal wall into said branch pipes, continue to flow substantially in said rectilinear direction within said initial length portions of said branch pipes, thereby preventing premature separation of said solids within said branch pipes.
Claim 2
Dependent Claim
227 words
A cyclone separator assembly for use in separating solids such as coal from a carrier gas conveying such solids, said assembly comprising: conveying pipe means for conveying a carrier gas and solids conveyed thereby along a flow path extending in a rectilinear direction; a diagonal wall extending across said conveying pipe means in a direction which is diagonally inclined with respect to said rectilinear direction; a plurality of cyclone separators located adjacent said diagonal wall; and branching pipe means for transferring said carrier gas and solids from said conveying pipe means to said cyclone separators, whereat said solids and carrier gas are separated, said branching pipe means comprising a plurality of branch pipes, one said branch pipe for each said cyclone separator, each said branch pipe having a first end connected to said diagonal wall and opening into said conveying pipe means and a second end connected to and opening into a respective said cyclone separator, at least an initial length portion of each said branch pipe, taken from said first end thereof, extending in a direction substantially parallel to said rectilinear direction, such that said solids and carrier gas, upon passing said diagonal wall into said branch pipes, continue to flow substantially in said rectilinear direction within said initial length portions of said branch pipes, thereby preventing premature separation of said solids within said branch pipes.
Claim 3
Dependent Claim
38 words
An assembly as claimed in claim 1, wherein said plurality of cyclone separators are all substantially positioned adjacent said diagonal wall in a free space substantially formed by the projection of an extension of said conveying pipe means.
Claim 4
Dependent Claim
64 words
An assembly as claimed in claim 1, wherein said plurality of cyclone separators includes a first group of cyclone separators arranged in a first row extending substantially parallel to said diagonal wall and positioned closely adjacent said diagonal wall, said branch pipes of said first group of cyclone separators extending throughout substantially the entire lengths thereof in directions substantially parallel to said rectilinear direction.
Claim 5
Dependent Claim
124 words
An assembly as claimed in claim 3, wherein said plurality of cyclone separators further includes a second group of cyclone separators arranged in a second row positioned behind and closely adjacent said first row, each said branch pipe of said second group of cyclone separators extending between an adjacent pair of said first group of cyclone separators, each said branch pipe of said second group of cyclone separators including a respective said initial length portion extending in said direction substantially parallel to said rectilinear direction and a curved following section connected to the respective said cyclone separator and having a curvature such that no portion of said following section extends at an angle less than an obtuse angle with respect to said rectilinear direction.
Claim 6
Dependent Claim
45 words
An assembly as claimed in claim 1, wherein said cyclone separators, said branch pipes, said diagonal wall and at least a portion of said conveying pipe means are formed as a single integral unit which can readily be connected to and disconnected from a pipeline.
Claim 7
Dependent Claim
24 words
An assembly as claimed in claim 1, wherein said second ends of said branch pipes are connected tangentially to the respective said cyclone separators.
Claim 8
Dependent Claim
26 words
An assembly as claimed in claim 1, wherein said first ends of said branch pipes collectively take up substantially the entire area of said diagonal wall.
Claim 9
Dependent Claim
39 words
An assembly as claimed in claim 1, further comprising a carrier gas removal pipe means, connected to top portions of said cyclone separators by means of pipe connections, for removing said carrier gas after separation thereof from said solids.
Claim 10
Dependent Claim
30 words
An assembly as claimed in claim 1, further comprising collecting means, connected to lower portions of said cyclone separators, for removing said solids after separation thereof from said carrier gas.
Claim 11
Dependent Claim
28 words
An assembly as claimed in claim 9, wherein said collecting means comprise plural collecting containers, each said collecting container being connected to a pair of said cyclone separators.
