Gas scrubbing device

Claim 2

A gas scrubbing device which comprises an annular body, a housing of substantially U-shape in section mounted inside the body and defining an annular space between the body and the housing and a central cavity inside the housing, means for introducing a liquid under pressure into the annular space, means for directing particle-containing gas into the central cavity, a plurality of jet nozzles receiving liquid from the annular space and mounted in a flange of the housing, discharge ends of the jet nozzles being in communication with the central cavity, means for closing an end of the central cavity adjacent discharge ends of the jet nozzles, the means for closing the end of the central cavity being a wall extending transversely of the direction of introduction of the particle containing gas to cause divergent turbulent flow of the particle containing gas at the jet nozzles, there being openings in the closing means aligned with the discharge ends of the jet nozzles, there being mixing chambers receiving liquid from the nozzles and particle-containing gas from the central cavity to mix the gas and liquid intimately to scrub the particles from the gas, means for receiving a mixture of gas and liquid from the mixing chambers and separating the gas from the liquid and particles carried by the liquid, and means for separating particles carried by the liquid from the liquid.

Claim 3

A gas scrubbing device as in claim 1 wherein the means for directing particle-containing gas into the central cavity is at the end of the housing opposite to the closing means and the jet nozzles are directed parallel to the axis of the housing and away from said directing means and the jet nozzles are arranged around the central cavity to draw from all sides thereof.

Claim 4

A gas scrubbing device as in claim 2 wherein there are at least eight jet nozzles substantially equally spaced around the central cavity.

Claim 5

A gas scrubbing device as in claim 1 wherein each of the mixing chambers includes an inwardly contracting frusto-conic inlet section, an elongated cylindrical central mixing section, and an outwardly expanding frusto-conic discharge section.

Claim 6

A gas scrubbing device as in claim 1 wherein a second flange of the housing is attached to an end of the housing remote from the closed end, the gas directing means directs particle-carrying gas into the central cavity at the second flange and axially of the housing, the jet nozzles are directEd parallel to the axis of the housing and away from the gas directing means, and the jet nozzles are substantially equally spaced around the central cavity.

Claim 7

A gas scrubbing device which comprises an annular body defining a chamber having an open end and a bottom spaced therefrom, a spool-like housing of substantially U-shape in radial section mounted inside the body and extending from adjacent the open end toward the bottom and defining an annular space between the body and the housing and a central cavity inside and extending through the housing into communication with the chamber, means for introducing a liquid under pressure into the annual space, means for directing particle-containing gas into the central cavity, a plurality of jet nozzles receiving liquid from the annular space and mounted in a flange of the housing radially outwardly of the central cavity projected and adjacent and spaced from the said bottom, discharge ends of the jet nozzles being in communication with the chamber and extending toward said bottom, the portion of the bottom opposite the central cavity being imperforate and extending transversely of the direction of introduction of the particle-containing gas to cause divergent turbulent flow of the particle-containing gas in the chamber between the nozzle carrying the flange and the bottom, there being openings in the bottom opposite and aligned with the discharge ends of the jet nozzles, there being mixing chambers secured to the body in alignment with the openings for receiving liquid from the nozzles and particle-containing gas from the chamber to mix the gas and liquid intimately to scrub the particles from the gas, means for receiving a mixture of gas and liquid from the mixing chambers and separating the gas from the liquid and particles carried by the liquid, and means for separating particles carried by the liquid from the liquid.

Claim 8

A gas scrubbing device which comprises an annular body defining a chamber having an open end and a bottom spaced therefrom, a spool-like housing of substantially U-shape in radial section mounted inside the body and extending from adjacent the open end toward the bottom and defining an annular space between the body and the housing and a central cavity inside and extending through the housing into communication with the chamber, means for introducing a liquid under pressure into the annual space, means for directing particle-containing gas into the central cavity, a plurality of jet nozzles receiving liquid from the annular space and mounted in a flange of the housing radially outwardly of the central cavity projected and adjacent and spaced from the said bottom, discharge ends of the jet nozzles being in communication with the chamber and extending toward said bottom, the portion of the bottom opposite the central cavity being imperforate and extending transversely of the direction of introduction of the particle-containing gas to cause divergent turbulent flow of the particle-containing gas in the chamber between the nozzle carrying the flange and the bottom, there being openings in the bottom opposite and aligned with the discharge ends of the jet nozzles, there being mixing chambers secured to the body in alignment with the openings for receiving liquid from the nozzles and particle-containing gas from the chamber to mix the gas and liquid intimately to scrub the particles from the gas, means for receiving a mixture of gas and liquid from the mixing chambers and separating the gas from the liquid and particles carried by the liquid, and means for separating particles carried by the liquid from the liquid.

Claim 9

In a device according to claim 6, the body being readily demountable from the gas and liquid mixture receiving means whereby the mixing chambers may be easily replaced when worn.

Claim 10

In a device according to claim 6, the spool-like housing with nozzles mounted thereon being releasable to slide out of the chamber for examination, servicing and replacement of nozzles.

Claim 11

In a device according to claim 6, the body being readily demountable from the gas and liquid mixture receiving means whereby the mixing chambers may be easily replaced when worn and the spool-like housing with nozzles mounted thereon being releasable to slide out of the chamber for examination, servicing and replacement of nozzles.
