Abstract
Abstract A fluid distributor, especially for an electrostatic precipitator or the like, in which the fluid stream passes from a conduit of small cross-section into a region of larger crosssection, as in a diffuser, and the throttle and guide devices include a distributor plane in which V-section throttle elements are provided with a direction of convergence facing toward a source of dust or other particles and substantially independent of the gas-flow direction. The flanks of the V-section distributor are slotted alternately and the closeness or spread of the V-section member can be adjusted to suit distribution requirements. Below the distributor plane is an array of deflector blades of generally Y-shaped cross-section with shanks in stepped relationship along the gas-flow path.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
169 words
A device for feeding a fluid to a chamber comprising: a housing forming a duct opening at one end into said chamber and communicating at another end with a source of fluid; and a planar array of mutually parallel throttle elements extending across the cross-section of said duct, each of said throttle elements having a V-cross section with codirectionally facing ridges, and aprons divergent from said ridges, said chamber being a treatment space containing means spaced from said one end of said duct for treating said fluid, said fluid being a gas and solid particles descending from said chamber through said array of throttle elements, said ridges being turned toward said chamber, each of said throttle elements comprising a support beam of T-cross-section having a shank and a cross bar, and at least one sheet-metal strip defining said aprons and resting on said beam with the ridge of said strip extending along the shank of the T and flanks of said strips resting against the ends of said cross-bar.
Claim 2
Independent Claim
169 words
A device for feeding a fluid to a chamber comprising: a housing forming a duct opening at one end into said chamber and communicating at another end with a source of fluid; and a planar array of mutually parallel throttle elements extending across the cross-section of said duct, each of said throttle elements having a V-cross section with codirectionally facing ridges, and aprons divergent from said ridges, said chamber being a treatment space containing means spaced from said one end of said duct for treating said fluid, said fluid being a gas and solid particles descending from said chamber through said array of throttle elements, said ridges being turned toward said chamber, each of said throttle elements comprising a support beam of T-cross-section having a shank and a cross bar, and at least one sheet-metal strip defining said aprons and resting on said beam with the ridge of said strip extending along the shank of the T and flanks of said strips resting against the ends of said cross-bar.
Claim 3
Dependent Claim
19 words
The device defined in claim 1 further comprising means for adjustably shifting said throttle elements in the plane thereof.
Claim 4
Dependent Claim
31 words
The device defined in claim 1 wherein each of said throttle elements comprises a single strip resting upon the respective beam and formed with slots longitudinally spaced apart along each apron.
Claim 5
Dependent Claim
17 words
The device defined in claim 3 wherein the slots and the aprons of each element alternate therealong.
Claim 6
Dependent Claim
45 words
The device defined in claim 1 wherein each of said elements is provided with a multiplicity of contiguous bent metal strips having long and short legs disposed alternatively on opposite side of the respective beam to form alternating slots along the aprons of said elements.
Claim 7
Dependent Claim
46 words
The device defined in claim 1 wherein said source communicates with said duct at an angular junction, said device further comprising an array of transversely spaced mutually parallel deflector slats disposed at said junction and lying in planes perpendicular to the plane of said throttle elements.
Claim 8
Dependent Claim
87 words
The device defined in claim 6 wherein said slats are of stepwise increasing height in the direction of fluid flow with bottom edges terminating in a diagonal plane through a junction and upper edges terminating in a plane parallel to the plane of said throttle elements, said upper edges of said slats being provided with arrays of tongues bent alternately in opposite directions to impart a Y-section to each slat, said tongues extending toward said throttle elements from the plane of the upper edges of said slats.
Claim 9
Dependent Claim
15 words
The device defined in claim 7 wherein said chamber forms part of an electrostatic precipitator.
Claim 10
Dependent Claim
178 words
In a device for feeding a fluid to a chamber comprising a housing forming a duct opening at one end into said chamber and communicating at another end with a source of fluid, wherein said chamber contains means to treat the fluid, said means to treat the fluid being spaced from said one end of said duct, and a planar array of mutually parallel throttle elements extending across the cross section of said duct, each of said throttle elements having a V-cross section with codirectionally facing ridges and aprons divergent from said ridges and wherein said fluid is a gas and solid particles descend from said chamber through said array of throttle elements, said ridges being turned toward said chamber, the improvement wherein each of said throttle elements comprises a support beam of T-cross section having a shank and a cross-bar and at least one sheet metal strip defining said aprons and resting on said beam with the ridge extending along the shank of the T and flanks of said strips resting against the ends of said crossbar.
Claim 11
Dependent Claim
178 words
In a device for feeding a fluid to a chamber comprising a housing forming a duct opening at one end into said chamber and communicating at another end with a source of fluid, wherein said chamber contains means to treat the fluid, said means to treat the fluid being spaced from said one end of said duct, and a planar array of mutually parallel throttle elements extending across the cross section of said duct, each of said throttle elements having a V-cross section with codirectionally facing ridges and aprons divergent from said ridges and wherein said fluid is a gas and solid particles descend from said chamber through said array of throttle elements, said ridges being turned toward said chamber, the improvement wherein each of said throttle elements comprises a support beam of T-cross section having a shank and a cross-bar and at least one sheet metal strip defining said aprons and resting on said beam with the ridge extending along the shank of the T and flanks of said strips resting against the ends of said crossbar.
