Abstract
Abstract The invention relates to a device for the separation of liquids and/or solids from a gas stream, comprising a cylindrical vessel with a virtually vertically set axis, provided with: a top compartment to which the gas stream is supplied; a middle compartment comprising a number of blades shaped helicoidally around the axis; a bottom compartment for the separation of the liquid and/or solids and a coaxial gas discharge pipe projecting upwards from the bottom compartment through the middle and top compartments, around which the helicoidal blades are fixed, in which bottom compartment at least one plate with a circular outer rim is provided perpendicularly to the axis of the vessel and under the gas discharge pipe, at least one diametrical baffle being provided beneath the bottom plate, the overall height of each baffle being at least 1.0 times the internal diameter of the vessel. <IMAGE>

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
190 words
A device for separating liquids and/or solids from a gas stream, comprising: a cylindrical vessel having an axis and an internal diameter; a first housing portion forming one end of said vessel, said first end housing portion having an inlet means for supplying said gas stream; a central housing portion connected to said first end housing portion; a plurality of blades arranged for rotation of said gas stream about said axis in said central housing portion; a second housing portion forming the other end of said vessel for separating said liquid and/or solids; a coaxial gas discharge pipe projecting through said central and said first end housing portions, said blades fixed around said coaxial discharge pipe, said second end housing portion having at least one settling plate arranged perpendicularly to said vessel axis; at least one diametrical baffle provided beneath said settling plate for suppressing rotation, and causing settlement, of said liquids and/or solids separated from said gas, each of said diametrical baffles having a slot that extends from a bottom edge of sad diametrical baffle parallel to said axis of said vessel along the entire extent of said slot.
Claim 2
Independent Claim
190 words
A device for separating liquids and/or solids from a gas stream, comprising: a cylindrical vessel having an axis and an internal diameter; a first housing portion forming one end of said vessel, said first end housing portion having an inlet means for supplying said gas stream; a central housing portion connected to said first end housing portion; a plurality of blades arranged for rotation of said gas stream about said axis in said central housing portion; a second housing portion forming the other end of said vessel for separating said liquid and/or solids; a coaxial gas discharge pipe projecting through said central and said first end housing portions, said blades fixed around said coaxial discharge pipe, said second end housing portion having at least one settling plate arranged perpendicularly to said vessel axis; at least one diametrical baffle provided beneath said settling plate for suppressing rotation, and causing settlement, of said liquids and/or solids separated from said gas, each of said diametrical baffles having a slot that extends from a bottom edge of sad diametrical baffle parallel to said axis of said vessel along the entire extent of said slot.
Claim 3
Dependent Claim
19 words
The device as set forth in claim 1, wherein said second end housing portion has two perpendicular diametrical baffles.
Claim 4
Dependent Claim
13 words
The device as set forth in claim 1, wherein said slot is rectangular.
Claim 5
Dependent Claim
26 words
The device as set forth in claim 1, wherein the height of each diametrical baffle is at least equal to said internal diameter of said vessel.
Claim 6
Dependent Claim
25 words
The device as set forth in claim 1, wherein the height of said slot is at least 0.6 times said internal diameter of said vessel.
Claim 7
Dependent Claim
43 words
The device as set forth in claim 1, wherein a portion of each of said diametrical baffles extends the entire diameter of said vessel, said portion of said diametrical baffle having a height at least 0.4 times said internal diameter of said vessel.
Claim 8
Dependent Claim
36 words
The device as set forth in claim 1, wherein the size of said slot in a direction perpendicular to said axis of said vessel is approximately 0.25 to 0.5 times said internal diameter of said vessel.
Claim 9
Dependent Claim
40 words
The device as set forth in claim 1, wherein the distance from a bottom edge of said settling plate to a top edge of each of said diametrical baffles is at least 0.5 times said internal diameter of said vessel.
Claim 10
Dependent Claim

Claim 11
Dependent Claim
34 words
The device as set forth in claim 1, wherein second end housing portion of said vessel is conically shaped in the direction of a discharge pipe for the discharge of separated liquids and/or solids.
Claim 12
Dependent Claim
14 words
The device as set forth in claim 1, wherein said blades are helicoidally shaped.
Claim 13
Independent Claim
209 words
A device for separating liquids and/or solids from a gas stream, comprising: a cylindrical vessel having an axis and an internal diameter; a first housing portion forming one end of said vessel, said first end housing portion having an inlet means for supplying said gas stream; a central housing portion connected to said first end housing portion; a plurality of blades arranged for rotation of said gas stream about said axis in said central housing portion; a second housing portion forming the other end of said vessel for separating said liquid and/or solid; a coaxial gas discharge pipe projecting through said central and said first end housing portion, said blades fixed around said coaxial discharge pipe, said second end housing portion having at least one settling plate arranged perpendicularly to said vessel axis; said second end housing portion having two perpendiculars diametrical baffles provided beneath said settling plate for suppressing rotation, and causing settlement, of said liquids and/or solids separated from said gas, each of said diametrical baffles having a slot that extends from a bottom edge of said diametrical baffle parallel to said axis of said vessel, and each of said diametrical baffles having a top edge that is partially detached from an inner wall of said vessel.
