Abstract

Abstract An irradiator of the type using radioactive material as a source of radiation having a casing for holding an irradiator core and inputs and outputs passing through the casing to the core. The core includes a plurality of concentric walls forming chambers with the flow of fluid passing from one chamber to the next and then out of the irradiator. A plurality of radiation sources are located in the core and a system for feeding predetermined gases through a liquid being treated in the core and for bleeding excess gases out of the core is provided. The gas inputs are located to provide a turbulence in the liquid along the walls for keeping the irradiator clean as well as for increasing the effectiveness of the irradiator and the use of pre-selected gases improves the treatment by the combined action of the gases and irradiation of the fluid.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 168 words
Apparatus for treating polluted fluids comprising in combination: a. a casing including a plurality of inputs and outputs therefrom; b. core means located in said casing defined a flowpath for liquid therethrough from at least one input to at least one output; c. said core means having a central overflow pipe and a plurality of chambers each chamber being operatively connected to at least one other chamber for the feeding of liquid from one to the other and out the overflow pipe; d. radiation sources located in said core means for irradiating liquids passing therethrough; e. gas feed means operatively connected to said core means for feeding a gas into said core means through liquid passing through said core means; f. bleed means located to allow accumulated gases in said core means to escape therefrom; and g. baffle means located in spaced relationship to at least one gas feed means through said liquid in said core means, whereby liquid passing through said apparatus is irradiated during chemical treatment.
Claim 2
Dependent Claim 168 words
Apparatus for treating polluted fluids comprising in combination: a. a casing including a plurality of inputs and outputs therefrom; b. core means located in said casing defined a flowpath for liquid therethrough from at least one input to at least one output; c. said core means having a central overflow pipe and a plurality of chambers each chamber being operatively connected to at least one other chamber for the feeding of liquid from one to the other and out the overflow pipe; d. radiation sources located in said core means for irradiating liquids passing therethrough; e. gas feed means operatively connected to said core means for feeding a gas into said core means through liquid passing through said core means; f. bleed means located to allow accumulated gases in said core means to escape therefrom; and g. baffle means located in spaced relationship to at least one gas feed means through said liquid in said core means, whereby liquid passing through said apparatus is irradiated during chemical treatment.
Claim 3
Dependent Claim 32 words
The apparatus in accordance with claim 1 in which said chambers have concentric walls with openings for said liquid to flow over at least one wall and under at least one wall.
Claim 4
Dependent Claim 26 words
The apparatus in accordance with claim 1 including sampling means for sampling the liquid passing through said core at a plurality of points in said core.
Claim 5
Dependent Claim 32 words
The apparatus in accordance with claim 1 in which said gas feed means are located in said core for said gas fed therefrom to agitate said liquid for cleaning said core means.
Claim 6
Dependent Claim 66 words
The apparatus in accordance with claim 1 in which said casing has a plurality of cylindrical walls and has an entrance for removing at least one cylindrical wall from said core and said casing forms the outside wall of the outermost chamber in said core, said entrance being smaller than said entire core and larger than said core without the outer wall of the outermost chamber.
Claim 7
Dependent Claim 175 words
Apparatus for treating polluted fluids comprising in combination: a. a casing having a plurality of inputs and outputs therefrom; b. core means located in said casing defining a flowpath for liquid therethrough from at least one input to at least one output; c. radiation sources located in said core means for irraDiating liquids passing therethrough; d. gas feed means operatively connected to said core means for feeding a gas into said core means through liquid passing through said core means, said gas feed means having a plurality of pipes connected to said core means for feeding gas to a plurality of chambers in said core means and means for feeding different gases to different chambers; e. bleed means located to allow accumulated gases in said core means to escape therefrom; and f. baffle means located in spaced relationship to at least one gas feed means to partially direct the flow of gas from said gas feed means through said liquid in said core means, whereby liquid passing through said apparatus is irradiated during chemical treatment.
Claim 8
Dependent Claim 175 words
Apparatus for treating polluted fluids comprising in combination: a. a casing having a plurality of inputs and outputs therefrom; b. core means located in said casing defining a flowpath for liquid therethrough from at least one input to at least one output; c. radiation sources located in said core means for irraDiating liquids passing therethrough; d. gas feed means operatively connected to said core means for feeding a gas into said core means through liquid passing through said core means, said gas feed means having a plurality of pipes connected to said core means for feeding gas to a plurality of chambers in said core means and means for feeding different gases to different chambers; e. bleed means located to allow accumulated gases in said core means to escape therefrom; and f. baffle means located in spaced relationship to at least one gas feed means to partially direct the flow of gas from said gas feed means through said liquid in said core means, whereby liquid passing through said apparatus is irradiated during chemical treatment.
