Definitions

  • the present invention relates to an apparatus for separating a two-phase flow or stream into a plurality of partial flows having a like liquid to gas ratio.
  • the above mentioned apparatus substantially comprise a separating chamber, to which leads a duct for supplying the gas-liquid mixture which is affected by suitably designed elements which so hinder the flow to provide inside the separating chamber a bottom region for collecting liquid therein and a top region for collecting gas therein.
  • separating chamber In said separating chamber are arranged a plurality of outlet tubes or lines which usually comprise ducts including a plurality of longitudinally extending slots, and which ducts axially extend inside the separating chamber and lead to the bottom portion of the latter.
  • the aim of the present invention is to overcome the above mentioned problems, by providing an apparatus for separating a two-phase flow into a plurality of partial flows, with a like liquid to gas ratio, allowing to always obtain a constant ratio of the liquid and gas.
  • a main object of the present invention is to provide such an apparatus assuring, by a very simple construction, an optimum operation under different operating conditions.
  • Another object of the present invention is to provide such an apparatus which is very reliable and safe in operation.
  • Yet another object of the present invention is to provide such an apparatus for separating a two-phase flow or stream into a plurality of partial flows or streams, with a like liquid to gas ratio, which can be easily made by using easily available elements and materials and which, moreover, is very competitive from a mere economic standpoint.
  • an apparatus for separating a two-phase flow into a plurality of partial flows, with a like liquid to gas ratio comprising a separating chamber communicating with a duct for supplying a two-phase flow and defining a bottom region for collecting the liquid phase therein and a top region for collecting the gaseous phase therein, characterized in that said apparatus further comprises a plurality of outlet tubes, arranged in said separating chamber and leading to the top of said separating chamber through a top surface of said separating chamber.
  • the apparatus for separating a two-phase flow or stream into a plurality of partial flows or streams with a like liquid to gas ratio comprises an apparatus body 1, having preferably a substantially cylindric configuration, defining in its inside a separating chamber 2, which communicates with an inlet duct for supplying into said separating chamber a two-phase flow 3, said duct being substantially radially arranged of said body 1.
  • a separating wall 4 in front of said inlet duct, a separating wall 4 thereagainst is supplied the flow of the ducts 3, so as to facilitate the separation of the liquid phase from the gaseous phase, is arranged.
  • Said separating wall 4 defines a bottom gap 5 and a top gap 6, designing for reducing the rate of the two-phase flow, and to hold stable the free surface of the liquid held in said separating chamber 2.
  • the latter is provided with an inner bottom region 10 for collecting therein the liquid phase and a top region 11 for collecting therein the gaseous phase.
  • the main feature of the invention is that a plurality of outlet tubes 20 are provided, said outlet tubes being arranged beyond the region delimited by the mentioned separating wall 4 and, advantageously, being evenly distributed with respect to the center of the apparatus body 1.
  • the outlet tubes 20 are provided with a closed inner bottom 21 and a top opening 22, passing through the top cover of the separating chamber 2.
  • the outlet tubes 20 are provided, through their surface, with a plurality of longitudinally extending slots 30 which are variously distributed and which, advantageously, are open toward the inner portion of the separating chamber 2.
  • the above disclosed device which comprises a plurality of outlet tubes upward projecting, allows to always provide a constant ratio of the outlet liquid and gas flow ratio, independently from possible small inclinations with respect to the vertical line of the vessel axis.
  • the disclosed device allows to provide even liquid phase/gaseous phase ratios, through the outlet ducts, differently from the prior art approaches, while also providing a discrete region between the two-phase flow inlet region and the region therefrom the outlet tubes depart.
  • the used materials, as well as the contingent size and shapes can be any, depending on requirements.
