Abstract

Abstract A filter bed separator for separation of liquid or solid particulates from gas streams and/or for washing of accumulated solids from the filter bed. Each separator contains one or more cylindrical filter bed elements, each comprising a non-matting bed of filter material defining a hollow cylindrical filter bed element having a hollow core, with the filter bed terminating at the walls of a gas inlet duct. The gas inlet duct comprises one or more ducts disposed along at least a portion of the longitudinal length of the cylindrical element with the walls of the duct extending from outside the housing of the separator to the inner circumference of the filter bed.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 208 words
A filter bed separator for separation of a liquid from a moving gas stream, said separator comprising a housing having inlet and outlet means for the gas stream and drainage means for the separated liquid phase, and disposed within said housing at least one cylindrical fiber bed element with gas inlet duct means in communication with said inlet means of said housing, and baffle means in conjunction with each of said at least one cylindrical element to cause the gas stream to flow through the filter bed of each of said at least one cylindrical element from the hereinafter defined hollow core thereof radially outwardly; each of said at least one cylindrical element with gas inlet duct means comprising: (a) a non-matting bed of filter material of thickness defined by an inner and outer circumference, forming a substantially cylindrical filter bed having a hollow core, said filter bed circumferentially terminating at the walls of said gas inlet duct means; and (b) said gas inlet duct means comprising at least one elongated duct disposed along at least a substantial portion of the longitudinal length of the cylindrical element and the walls of which extend from at least said housing inlet means to the inner circumference of the filter bed.
Claim 2
Dependent Claim 208 words
A filter bed separator for separation of a liquid from a moving gas stream, said separator comprising a housing having inlet and outlet means for the gas stream and drainage means for the separated liquid phase, and disposed within said housing at least one cylindrical fiber bed element with gas inlet duct means in communication with said inlet means of said housing, and baffle means in conjunction with each of said at least one cylindrical element to cause the gas stream to flow through the filter bed of each of said at least one cylindrical element from the hereinafter defined hollow core thereof radially outwardly; each of said at least one cylindrical element with gas inlet duct means comprising: (a) a non-matting bed of filter material of thickness defined by an inner and outer circumference, forming a substantially cylindrical filter bed having a hollow core, said filter bed circumferentially terminating at the walls of said gas inlet duct means; and (b) said gas inlet duct means comprising at least one elongated duct disposed along at least a substantial portion of the longitudinal length of the cylindrical element and the walls of which extend from at least said housing inlet means to the inner circumference of the filter bed.
Claim 3
Dependent Claim 33 words
A filter bed separator as in claim 1 further having a means for irrigating or washing the filter bed disposed within the hollow core of each of said at least one cylindrical element.
Claim 4
Dependent Claim 43 words
A filter bed separator as in claim 2 wherein said irrigating or washing means is a pipe provided with a plurality of spray nozzles disposed so as to provide substantially uniform distribution of the liquid over the inner surface of the filter bed.
Claim 5
Dependent Claim 21 words
A filter bed separator as in claim 1 wherein the filter bed is a bed of glass, metal or plastic fibers.
Claim 6
Dependent Claim 35 words
A filter bed separator as in claim 1 wherein the walls of each of said at least one duct extend from outside said housing through said housing to the inner circumference of the filter bed.
Claim 7
Dependent Claim 32 words
A filter bed separator as in claim 1 wherein said at least one cylindrical element comprises a single cylindrical filter bed element with gas inlet duct means and disposed within said housing.
Claim 8
Dependent Claim 29 words
A filter bed separator as in claim 6 further having a means for irrigating or washing the filter bed disposed within the hollow core of said single cylindrical element.
Claim 9
Dependent Claim 43 words
A filter bed separator as in claim 7 wherein said irrigating or washing means is a pipe provided with a plurality of spray nozzles disposed so as to provide substantially uniform distribution of the liquid over the inner surface of the filter bed.
Claim 10
Dependent Claim 107 words
A cylindrical filter bed element for use in a filter bed separator for separation of a liquid from a moving gas stream comprising a non-mating bed of filter material of thickness defined by an inner and outer circumference, forming a cylindrical filter bed having a hollow core, said filter bed circumferentially terminating at the walls of a gas inlet duct means; said gas inlet duct means comprising at least one duct disposed along at least a substantial portion of the longitudinal length of said cylindrical element and the walls of which extend at least from the outer circumference of the filter bed to the inner circumference thereof.
Claim 11
Dependent Claim 107 words
A cylindrical filter bed element for use in a filter bed separator for separation of a liquid from a moving gas stream comprising a non-mating bed of filter material of thickness defined by an inner and outer circumference, forming a cylindrical filter bed having a hollow core, said filter bed circumferentially terminating at the walls of a gas inlet duct means; said gas inlet duct means comprising at least one duct disposed along at least a substantial portion of the longitudinal length of said cylindrical element and the walls of which extend at least from the outer circumference of the filter bed to the inner circumference thereof.
Claim 12
Dependent Claim 22 words
a cylindrical filter bed element as in claim 9 wherein the filter bed is a bed of glass, metal or plastic fibers.
