Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
182 words
A harness system for removing smoke from a combustion furnace comprising: a first collector chamber having an inlet pipe communicating with a combustion furnace, a second collector chamber having pipe means communicating with said first collector chamber and disposed below said first collector chamber, said second collector chamber having jet spray nozzle means for impinging water under pressure into said chamber, said second collector chamber including inlet gate means for introducing a chemical additive to said chamber in the area adjacent to said jet spray means, a third collector chamber having further pipe means communicating with said second collector chamber, said third collector chamber being disposed below said second collector chamber such that water introduced into said second collector chamber by said jet spray means is delivered, by gravity, to said third collector chamber, said third collector chamber being disposed in fluid communication with a filter means, and fluid pump means disposed for delivering liquid under pressure in said third collector chamber into said filter means, and said filter means having outlet means for discharging water introduced into said second collector chamber.
Claim 2
Dependent Claim
182 words
A harness system for removing smoke from a combustion furnace comprising: a first collector chamber having an inlet pipe communicating with a combustion furnace, a second collector chamber having pipe means communicating with said first collector chamber and disposed below said first collector chamber, said second collector chamber having jet spray nozzle means for impinging water under pressure into said chamber, said second collector chamber including inlet gate means for introducing a chemical additive to said chamber in the area adjacent to said jet spray means, a third collector chamber having further pipe means communicating with said second collector chamber, said third collector chamber being disposed below said second collector chamber such that water introduced into said second collector chamber by said jet spray means is delivered, by gravity, to said third collector chamber, said third collector chamber being disposed in fluid communication with a filter means, and fluid pump means disposed for delivering liquid under pressure in said third collector chamber into said filter means, and said filter means having outlet means for discharging water introduced into said second collector chamber.
Claim 3
Dependent Claim
25 words
A system in accordance with claim 1, wherein said first collector chamber includes baffle plate means disposed for removing solid particles from said flue gases.
Claim 4
Dependent Claim
33 words
A system in accordance with claim 1, wherein said second collector chamber has timer means associated with said jet spray means for regulating the flow of water to the interior of said chamber.
Claim 5
Dependent Claim
35 words
A system in accordance with claim 1, wherein first and second blower means are operably associated with said first and second collector chambers for deivering said flue gases under pressure to said second collector chamber.
Claim 6
Dependent Claim
29 words
A system in accordance with claim 1, wherein said filter means includes an upstanding housing enclosing a fabric mesh for removing particulate material pumped from said third collector chamber.
Claim 7
Dependent Claim
49 words
A system in accordance with claim 1, wherein pump means are disposed for pumping water from said third collector chamber into said filter means, and said filter means having outlet means adapted to be connected back to said second collector chamber for recycling the water in a continuous process.
Claim 8
Dependent Claim
178 words
A process for controlling pollution resulting from flue gases like coal as produced from a combustion furnace, the steps comprising a source of combustion of flue gases like smoke, delivering said smoke to a first collector chamber and separating larger size entrained particles from said smoke in said chamber, delivering the smoke from said first collector chamber to a second collector chamber, bringing the smoke in said second collector chamber into contact with a jet-like water spray in said chamber, selectively feeding a chemical mixture into said second collector chamber in the vacinity of said jet-like water spray, delivering said smoke from said second collector chamber into a third collector chamber, said second and third collector chambers each being at least partially filled with water and continuously introducing water into said second collector chamber and delivering the water in said second collector chamber by gravity, to said third collector chamber, delivering the water from said third collector chamber to a filter means and filtering entrained particles from said water, and discharging the filter water from said filter means.
Claim 9
Dependent Claim
178 words
A process for controlling pollution resulting from flue gases like coal as produced from a combustion furnace, the steps comprising a source of combustion of flue gases like smoke, delivering said smoke to a first collector chamber and separating larger size entrained particles from said smoke in said chamber, delivering the smoke from said first collector chamber to a second collector chamber, bringing the smoke in said second collector chamber into contact with a jet-like water spray in said chamber, selectively feeding a chemical mixture into said second collector chamber in the vacinity of said jet-like water spray, delivering said smoke from said second collector chamber into a third collector chamber, said second and third collector chambers each being at least partially filled with water and continuously introducing water into said second collector chamber and delivering the water in said second collector chamber by gravity, to said third collector chamber, delivering the water from said third collector chamber to a filter means and filtering entrained particles from said water, and discharging the filter water from said filter means.
Claim 10
Dependent Claim
25 words
A process in accordance with claim 7, including continuously adding said chemical mixture to said second collector tank, and said mixture including calcium and sulphur.
Claim 11
Dependent Claim
22 words
A process in accordance with claim 8, wherein the calcium and sulphur are present in the weight ratio of 4 to 1.
Claim 12
Dependent Claim
41 words
A process in accordance with claim 9, wherein said water is continuously circulated to said system at a flow rate of approximately 60 gallons per hour and said chemical addition is made at the rate of approximately 5 pounds per hour.
Claim 13
Dependent Claim
27 words
A process in accordance with claim 9, wherein the output water from said filter means is recycled back to said second collector chamber for a continuous operation.
