Abstract

Abstract A smoke cleaning apparatus has been provided for effecting the cleaning of the smoke particles from the smoke and the absorption of the gasses by water spray or pressure injected devices. The apparatus is formed of top and bottom parts, a mesh basket supported on the bottom part and a filter supporting ring disposed in the mesh basket and having vertically spaced inwardly extending flanges and a filtering mass unit having a tapered side surface fitting and conforming generally to the edges of the inwardly extending flanges of the ring to provide annular spaces about the filtering mass communicating with the tapered side face of the filtering mass to allow for entry and re-entry of the smoke into the filtering mass to provide for maximum use of the filtering material. A suction fan is provided in the bottom part for effecting generally the suction of the smoke through the filtering mass and in the outward conduit from the suction fan the water spray, or the water injected cylinder device is connected.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 158 words
A smoke cleaning apparatus, having a casing, including a top casing, provided with an inlet and a bottom casing, providing a bottom chamber for receiving and connected to the top casing, the bottom casing having a supporting shoulder, a mesh basket resting on the supporting shoulder and a ring supported in the basket, said ring having a plurality of inwardly extending perimetrical flanges varying in width from a smaller size flange at the top to a large size flange at the bottom, a filtering mass having a downwardly and inwardly tapered side wall fitting the inner edges of the flanges of said ring to provide annular spaces for the escape and distribution of smoke from the sides of the filtering mass, and suction fan means connected to the bottom casing for effecting the downward passage of the smoke through the filtering material and the annular spaces between the ring and the tapered outer surface of the filtering material.
Claim 2
Dependent Claim 158 words
A smoke cleaning apparatus, having a casing, including a top casing, provided with an inlet and a bottom casing, providing a bottom chamber for receiving and connected to the top casing, the bottom casing having a supporting shoulder, a mesh basket resting on the supporting shoulder and a ring supported in the basket, said ring having a plurality of inwardly extending perimetrical flanges varying in width from a smaller size flange at the top to a large size flange at the bottom, a filtering mass having a downwardly and inwardly tapered side wall fitting the inner edges of the flanges of said ring to provide annular spaces for the escape and distribution of smoke from the sides of the filtering mass, and suction fan means connected to the bottom casing for effecting the downward passage of the smoke through the filtering material and the annular spaces between the ring and the tapered outer surface of the filtering material.
Claim 3
Dependent Claim 57 words
A smoke cleaning apparatus, as defined in claim 1, and an outlet conduit extending from the suction fan device and a water spray device provided in the conduit comprising a water inlet and spray nozzle adapted to deliver a water spray to fill the conduit, and a sump for collecting the water used by the spray device.
Claim 4
Dependent Claim 71 words
A smoke cleaning apparatus, as defined in claim 1, and a water piston cylinder device provided in the conduit receivable of gas-containing smoke from the conduit and said water-piston cylinder device being forceable of water through the smoke to absorb gases within said smoke into the water, an outlet means by which the water having gases absorbed therein can be forced to exit from the cylinder device and from the conduit.
Claim 5
Dependent Claim 182 words
A smoke cleaning apparatus, as defined in claim 3, and said cylinder device including a valve controlled bypass extending from one end of the cylinder to the other, a water inlet to the end of the cylinder removed from the smoke inlet end thereof through which water is passed to the cylinder device, said piston upon being moved toward the smoke receiving end of the cylinder receiving water from the water inlet and forcing water through the bypass to the smoke end of the cylinder to conmingle with gasses received therefrom, said smoke end of the cylinder having a discharge outlet through which the water with the gasses are forced upon the piston being moved toward the smoke receiving end of the cylinder, a one -way ball valve in the smoke receiving end of the cylinder for controlling the smoke entering therein to, said water inlet, opposite ends of the bypass and the water outlet on the cylinder having one-way valves for controlling the passage of water into the cylinder, between the opposite ends of the cylinder and out of the cylinder.
