Abstract
Abstract An apparatus for separating gases from fluids, which apparatus includes a closed cylindrical receptacle and a cylindrical insert which divides the interior of the receptacle into an annular outer part and a cylindrical inner part. The outer part is provided with a tangential inlet for the fluid. Near the top, an opening connects the outer part to the inner part, the latter being provided with a ventilation device. The outer annular part is divided in the axial direction by a partition which ascends spirally from the tangential inlet approximately in a complete turn in the direction of the upper end face cover of the receptacle. The connection opening is formed by an annular clearance which extends over nearly the entire circumference of the receptacle. A similar annular clearance at the bottom of the receptacle connects the inner cylindrical part with the outer annular part, the latter having a tangential discharge outlet in this region.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
233 words
An apparatus for separating gas from a fluid, which comprises in combination: a hollow cylindrical receptacle, the ends of which respectively comprise cover means; a hollow cylindrical insert located within said receptacle and in spaced relationship thereto so as to define respective first and second annular gaps axially above and axially below between the end portions of said insert and said cover means and so as to divide the interior of said receptacle into an annular outer section and a cylindrical inner section, said outer section being provided with a tangentially oriented inlet positioned therein for receiving said fluid and a tangentially oriented outlet positioned in the lower portion of the outer section below the inlet for withdrawing said fluid in a uniform rotating film on the inner wall of said insert to facilitate and reinforce removal of gas supplemental to centrifugal forces from below at said second annular gap; a spirally ascending collar in said outer section and interposed between the inner wall of said receptacle and the outer circumference of said insert, said collar comprising a guiding surface thereon communicating with said inlet and following the spiral contour of said collar, said collar ascending upwardly in the direction of said first gap located axially there above and communicating therewith; and ventilating means communicating with said insert for withdrawing said gas from said receptacle with improved separation of gas from the fluid.
