Abstract
Abstract A gas purifying apparatus comprises a casing, a gas feeding opening for feeding said gas to said casing, a gas discharging opening for discharging said gas from said casing, and at least one liquid atomizing apparatus positioned in said casing. The liquid atomizing apparatus includes a rotary liquid-storing means mounted rotatably and having a circular liquid-storing groove on its periphery, nozzle means arranged adjacent to the periphery of said rotary liquid-storing means and communicating with said liquid-storing groove, liquid-feeding means feeding said liquidstoring groove with liquid, and a driving means rotating said rotary liquid-storing means. In this liquid-atomizing apparatus, the smaller the nozzle, the smaller the particle size of the atomized liquid.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
201 words
A gas purifying apparatus comprising a casing, a gas feeding opening for feeding said gas to said casing, a gas discharging opening for discharging said gas from said casing, and at least one liquid atomizing apparatus positioned in said casing, said liquid atomizing apparatus including a liquid storing means, means rotatably mounting said storing means for rotation about an axis parallel to the gas flow, a liquid storing groove defined by said storing means, nozzle means positioned on the periphery of said storing means and communicating with said groove, outlets of said nozzle means facing in a direction substantially parallel to the axis of rotation of said storing means and opposite to the direction of gas flow, feeding means for feeding liquid to said groove, and drive means for rotating said storing means, said feeding means injecting said liquid such that it has a component of force in the rotational direction of the rotating storing means whereby the injection of said liquid contributes to the rotation of said storing means, whereby the atomized liquid ejected spirally by centrifugal force from said nozzle means of said liquid atomizing apparatus is adapted to remove dust and desulfurize the gas passing through said casing.
Claim 2
Dependent Claim
201 words
A gas purifying apparatus comprising a casing, a gas feeding opening for feeding said gas to said casing, a gas discharging opening for discharging said gas from said casing, and at least one liquid atomizing apparatus positioned in said casing, said liquid atomizing apparatus including a liquid storing means, means rotatably mounting said storing means for rotation about an axis parallel to the gas flow, a liquid storing groove defined by said storing means, nozzle means positioned on the periphery of said storing means and communicating with said groove, outlets of said nozzle means facing in a direction substantially parallel to the axis of rotation of said storing means and opposite to the direction of gas flow, feeding means for feeding liquid to said groove, and drive means for rotating said storing means, said feeding means injecting said liquid such that it has a component of force in the rotational direction of the rotating storing means whereby the injection of said liquid contributes to the rotation of said storing means, whereby the atomized liquid ejected spirally by centrifugal force from said nozzle means of said liquid atomizing apparatus is adapted to remove dust and desulfurize the gas passing through said casing.
Claim 3
Dependent Claim
89 words
A gas purifying apparatus according to claim 1, wherein said storing means comprises a rotating drum with an opening defined centrally of the drum communicating with said groove, and defining the height of the groove, said feeding means comprising a liquid supplying pipe extending to said opening and operating to supply liquid sufficient to overfill the groove, whereby said feeding means feeds extremely easily said groove with liquid and excess water in said groove flows outwardly through said opening to maintain a constant level of liquid in said groove.
Claim 4
Dependent Claim
41 words
A gas purifying apparatus according to claim 1 including a liquid sprinkling nozzle positioned to sprinkle gas entering said casing whereby the liquid sprinkled by said sprinkling nozzle removes mainly dust of larger particle size from the gas to be purified.
Claim 5
Dependent Claim
80 words
A gas purifying apparatus according to claim 1, wherein at least one liquid scattering device is arranged in said casing, and said liquid scattering device comprises rotary vane means provided with vanes for liquid-scooping having a groove for liquid-storing, driving means rotating said rotary vanes, and a tank for liquid-storing, whereby at least one part of said vanes for liquid-scooping dips into and out of a liquid line of said tank for liquid-storing on the rotating of said rotary vanes.
Claim 6
Dependent Claim
51 words
A gas purifying apparatus according to claim 4, wherein means for controlling said liquid line is disposed in said casing always to maintain said liquid line at the predetermined level, whereby the liquid scattering of the vanes for liquid scooping in said scattEring device is always maintained in the desired condition.
Claim 7
Dependent Claim
44 words
A gas purifying apparatus according to claim 5 wherein said means for controlling said liquid line comprises an opening defined by said casing whereby excess liquid overflows said casing and means for supplying liquid to said casing to maintain said liquid at said level.
Claim 8
Dependent Claim
31 words
A gas purifying apparatus according to claim 1 wherein at least one steam separator is positioned for contact with said gas after contact of the gas with said liquid atomizing apparatus.
Claim 9
Dependent Claim
26 words
A gas purifying apparatus according to claim 7 wherein said steam separator includes a plurality of meandering plates disposed substantially vertically and in spaced apart relationship.
Claim 10
Dependent Claim
18 words
A gas purifying apparatus according to claim 8 including at least one blower-means to forcibly ventilate said casing.
