Abstract

Abstract A gas-purifying device capable of removing solid and/or gaseous components from a flowing gas. The device includes a cyclone for receiving the gas and removing therefrom relatively coarse solid components, this cyclone having a tubular discharge having at an upper region in the interior of the cyclone a bottom open end through which the gas enters the tubular discharge after the relatively coarse solid components have been removed therefrom. Situated at least partly within the tubular discharge is a wet-washer for subjecting the gas flowing through the tubular discharge to a wet-washing action which removes from this gas relatively fine solid components and/or gaseous components, before the gas is discharged to the exterior of the cyclone. The wet-washer forms a sludge from the relatively fine components and/or gaseous components removed from the gas before discharge thereof to the exterior of the cyclone, and this sludge falls downwardly through the bottom open end of the tubular discharge along the interior of the cyclone. Situated beneath the bottom open end of the tubular discharge is a receiving structure which receives the sludge falling from the tubular discharge.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 493 words
A device for removing solid and/or gaseous components from a gas, comprising: upright cyclone means having a gas inlet for receiving the gas and for removing relatively coarse solid components therefrom, said cyclone means including a central tubular discharge means having a top wall formed with an opening passing therethrough for discharging the gas from which the relatively coarse solid components have been removed out of the cyclone means, said tubular discharge means having in said cyclone means a bottom open end through which the gas with relatively fine solid components and/or gaseous components therein enters said tubular discharge means to flow therethrough toward the exterior of the cyclone means, rotary, unitary wet-washer means situated at least in part in said tubular discharge means for providing therein an umbrella of washing liquid spreading radially from a lower end of said washing means to an inner surface of said tubular discharge means for subjecting the gas flowing therethrough toward the exterior of the cyclone means to a wet-washing and drying action for removing from the gas the finer solid components and/or gaseous components therein and for drying the gas before the gas discharges to the exterior of the cyclone means, said wet-washing means including an internal blower means situated in said tubular means adjacent said top wall thereof and an external blower means of a diameter greater than said internal blower means situated adjacent said top wall of said tubular discharge means at the exterior thereof, and said wet-washer means including a tubular means coaxial with both of said blower means, communicating with central regions thereof, and extending fluid-tightly tightly through said opening of said top wall of said tubular discharge means, so that gas discharged from said tubular discharge means passes first through said internal blower means then through said tubular means and finally through said external blower means, said internal blower means serving to separate from the gas droplets which are flung by said internal blower means against an inner surface of said tubular discharge means for drying the gas before the latter in purified condition flows through said tubular means to said exterior blower means, said wet-washer means, by said wet-washing action and by aid drying action thereof, producing from the relatively fine solid components and/or gaseous components a sludge which falls down through the open bottom end of said tubular discharge means along the interior of the cyclone means, and receiving means situated in its entirety in said cyclone means at a location spaced from and coaxially beneath said tubular discharge means for receiving the sludge falling therefrom downwardly along the interior of said cyclone means, the gas which enters said tubular discharge means through said bottom thereof first entering a space between said bottom open end of said tubular discharge means and said receiving means for acting in said space on said sludge to displace the latter toward a common axis of said tubular discharge means and receiving means.
Claim 2
Independent Claim 493 words
A device for removing solid and/or gaseous components from a gas, comprising: upright cyclone means having a gas inlet for receiving the gas and for removing relatively coarse solid components therefrom, said cyclone means including a central tubular discharge means having a top wall formed with an opening passing therethrough for discharging the gas from which the relatively coarse solid components have been removed out of the cyclone means, said tubular discharge means having in said cyclone means a bottom open end through which the gas with relatively fine solid components and/or gaseous components therein enters said tubular discharge means to flow therethrough toward the exterior of the cyclone means, rotary, unitary wet-washer means situated at least in part in said tubular discharge means for providing therein an umbrella of washing liquid spreading radially from a lower end of said washing means to an inner surface of said tubular discharge means for subjecting the gas flowing therethrough toward the exterior of the cyclone means to a wet-washing and drying action for removing from the gas the finer solid components and/or gaseous components therein and for drying the gas before the gas discharges to the exterior of the cyclone means, said wet-washing means including an internal blower means situated in said tubular means adjacent said top wall thereof and an external blower means of a diameter greater than said internal blower means situated adjacent said top wall of said tubular discharge means at the exterior thereof, and said wet-washer means including a tubular means coaxial with both of said blower means, communicating with central regions thereof, and extending fluid-tightly tightly through said opening of said top wall of said tubular discharge means, so that gas discharged from said tubular discharge means passes first through said internal blower means then through said tubular means and finally through said external blower means, said internal blower means serving to separate from the gas droplets which are flung by said internal blower means against an inner surface of said tubular discharge means for drying the gas before the latter in purified condition flows through said tubular means to said exterior blower means, said wet-washer means, by said wet-washing action and by aid drying action thereof, producing from the relatively fine solid components and/or gaseous components a sludge which falls down through the open bottom end of said tubular discharge means along the interior of the cyclone means, and receiving means situated in its entirety in said cyclone means at a location spaced from and coaxially beneath said tubular discharge means for receiving the sludge falling therefrom downwardly along the interior of said cyclone means, the gas which enters said tubular discharge means through said bottom thereof first entering a space between said bottom open end of said tubular discharge means and said receiving means for acting in said space on said sludge to displace the latter toward a common axis of said tubular discharge means and receiving means.
Claim 3
Dependent Claim 98 words
The combination of claim 1 and wherein said internal blower means has a bottom wall having a lower surface fixedly carrying vanes which rotate with said internal blower means, said wet-washer means including means situated adjacent said vanes for directing toward the latter and said bottom wall of said internal blower means said washing liquid which is distributed radially from said bottom wall of said internal blower means across the interior of said tubular discharge means to form therein said umbrella of liquid through which the flowing gas must pass before being received by said internal blower means.
Claim 4
Dependent Claim 58 words
The combination of claim 2 and wherein said wet-washer means includes a drive means operatively connected with both of said blower means and with said tubular means extending between and connected to both of said blower means for rotating both blower means and said tubular means extending therebetween as a unit with respect to said tubular discharge means.
