Abstract
The apparatus includes a steam separator between two successive stages of steam utilization that condensate liquid is automatically extracted with negligible impediment to high-velocity passage, to the second stage. The separator separates the liquid component by centrifugal action, into a region outside the region of gas discharge to the second stage, and an inverted-bucket steam trap is the means of continuously draining the separated condensate.
Claims8
A steam-utilization system, comprising a single supply of high-pressure steam and two successive stages of steam utilization, said first stage having an input connected to said supply and an output connection for continuously exhausting from said first stage a combined flow of steam and condensate and such other noncondensable products as may be contained therein, said second stage having an input connection of substantially the same volumetric flow-rate capacity as the output connection of said first stage, a separator chamber having an inlet and an outlet respectively connected to said first-stage output and to said second-stage input, said chamber including a generally conical array of swirl-inducing blades on an upstanding axis and effectively dividing the interior of said chamber into an upper region and a lower region, the chamber inlet being into the upper region and the chamber outlet comprising outletconduit means with an open end located within and above the bottom of the lower region, said open end being radially spaced from the chamber wall and facing said array, whereby a substantial fraction of the condensate content of the first-stage exhaust is collected at the bottom of the lower region without admission to said second-stage input connection, a condensate-drain outlet connection from the region of condensate collection in said chamber, and condensate-discharge means including an inverted-bucket steam trap, said drain outlet connection being positioned to discharge into the space within the inverted bucket of said trap.
A combined gas trap and liquid separator, comprising an upper gas-chamber body and a lower liquid-trap-chamber body removably carried by and beneath said gas-chamber body, said gas-chamber body having an upper inlet port for admission of a flow of liquid-gas mixture, flow-deflector means comprising a generally conical array of swirl-inducing blades carried within said gas-chamber body and effectively dividing the interior of said gas-chamber body into an upper inlet region and a lower discharge region, thereby imparting to the inlet flow of admitted mixture a rotary swirl about a central axis of flow, and thereby also centrifugally directing to an outer zone of greatest radii about said axis the liquid component of the mixture, a gas-outlet port including a conduit having an open inlet end above the bottom of the lower region and facing the flow discharged by said deflector means, said open end having an area confined to a central zone of lesser radii about said axis, trap means including an inverted bucket movably suspended within said trap-chamber body, and a liquid drain conduit extending from the outer zone of said gas-chamber body and positioned to discharge into the interior of said inverted bucket, said trap means including valve-controlled means discharging external to said bodies and having an operating connection to a movable part of the bucket suspension.
A combined gas trap and liquid separator comprising an upstanding generally cylindrical gas-chamber body having an inlet-chamber region and a discharge-chamber region separated by a generally conical array of swirl-inducing blades on an upstanding axis, an inlet connection to said inlet-chamber region for admitting a flow of liquid-gas mixture thereto, a gas-outlet connection to said discharge-chamber region and including a conduit with an open inlet end of area substantially less than that of said gas-chamber body and facing the axis of discharge of said array and located above the bottom of said gas-chamber body, a cupped trap housing removably secured at its open end to the bottom of said gas-chamber body, trap means including an inverted bucket movably suspended in the volume within said trap housing, a drain conduit extending from and through the bottom of said gas-chamber body into the included volume of said trap housing, said drain conduit being positioned to discharge into the inner volume of said inverted bucket, and trap-discharge passage means extending upwardly through the gas-chamber bottom and forming part of an external liquid-discharge connection to the gas-chamber body, said trap means including a valve in said trap-discharge passage means and operated by a movable part of the bucket suspension, whereby said trap housing may be removed without disturbing any of said connections.
