Abstract
Abstract Smoke washer apparatus which includes a smokestack having an exhaust flue in communication therewith. A series of sprinkler heads is located in the exhaust flue for spraying a curtain of water generally in the direction of the smokestack as that as exhaust passes through the flue, the curtain of water removes particulate and those gases soluble in water. The contaminantladen water gravitates to a collection tank and the cleaned smoke is directed to the smokestack for emission to the atmosphere. The contaminant is removed from the collection tank and the water recycled to the sprinkler heads.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
261 words
Smoke washer apparatus comprising: a. a smoke stack, b. a smoke flue, one end of which is in communication with said smoke stack, c. the opposite end of said smoke flue being provided with a smoke inlet, d. said smoke flue being of substantially the same crosssectional area throughout its length, e. the smoke flue including a first portion disposed downwardly at an angle to the horizontal, f. a plurality of water sprinkler heads positioned within said first portion of the flue, g. said sprinkler heads being arranged to provide an interlocking curtain of spray, which spray is directed longitudinally of said first flue portion, whereby the spray removes the contaminants from the smoke without impeding the flow of the smoke through said first portion of the flue, h. a primary collection tank in communication with the lower end of said first portion of the flue for receiving water and contaminants gravitating to the bottom of said first portion of the flue, i. means for delivering water from said primary collection tank to said sprinkler heads, j. a contaminant collection tank adjacent said primary collection tank, k. means for drawing off the contaminants from said primary collection tank into said contaminant collection tank, and l. a second flue portion in communication with the lower end of said first portion of the flue for receiving the washed smoke therefrom, m. said second portion of said flue extending upwardly from said first portion of the flue to an intermediate portion of said smoke stack, for delivering the washed smoke to the smoke stack.

Smoke washer apparatus comprising: a. a smoke stack, b. a smoke flue, one end of which is in communication with said smoke stack, c. the opposite end of said smoke flue being provided with a smoke inlet, d. said smoke flue being of substantially the same crosssectional area throughout its length, e. the smoke flue including a first portion disposed downwardly at an angle to the horizontal, f. a plurality of water sprinkler heads positioned within said first portion of the flue, g. said sprinkler heads being arranged to provide an interlocking curtain of spray, which spray is directed longitudinally of said first flue portion, whereby the spray removes the contaminants from the smoke without impeding the flow of the smoke through said first portion of the flue, h. a primary collection tank in communication with the lower end of said first portion of the flue for receiving water and contaminants gravitating to the bottom of said first portion of the flue, i. means for delivering water from said primary collection tank to said sprinkler heads, j. a contaminant collection tank adjacent said primary collection tank, k. means for drawing off the contaminants from said primary collection tank into said contaminant collection tank, and l. a second flue portion in communication with the lower end of said first portion of the flue for receiving the washed smoke therefrom, m. said second portion of said flue extending upwardly from said first portion of the flue to an intermediate portion of said smoke stack, for delivering the washed smoke to the smoke stack.
Claim 3
Dependent Claim
37 words
The smoke washer apparatus of claim 1, with the addition of: a. means for delivering water to said primary collection tank, and b. means for maintaining the water in said primary collection tank at a predetermined level.
Claim 4
Dependent Claim
271 words
Smoke washer apparatus comprising: a. a vertically disposed smoke stack, b. a smoke flue extending laterally in the direction of said smoke stack and connected at one end thereto, c. the opposite end of said smoke flue being provided with a smoke inlet, d. said smoke flue being of substantially the same cross-sectional area throughout its length, e. the smoke flue including a first portion inclined downwardly at approximately a 30* angle to the horizontal, f. a second portion which is inclined upwardly at approximately a 30* angle to the horizontal, g. the lower end of said second flue portion being in communication with the lower end of said first flue portion and the upper end of said second flue portion being in communication with said smoke stack, h. a series of spaced sprinkler heads positioned within the passageway of said first flue portion, i. said sprinkler heads being arranged to set up an interlocking curtain of spray whose line of flow is longitudinally of said first flue portion and generally in the direction of the smoke, j. a primary collection tank positioned beneath the lowest part of said flue, k. said first flue portion being provided with an opening at its lowermost end to permit gravitation of water and contaminants therethrough, l. a tubular member in the opening extending downwardly into the lower part of said primary collection tank, with the result that the heavier particles contained in the water gravitate towards the bottom thereof, and m. means for pumping water From the upper portion of said primary collection tank to said means for supplying water to said sprinkler heads.
