Abstract
Description
- 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.
- As is known, in refrigerating systems are conventionally used apparatus for separating a two-phase flow or stream into a plurality of partial flows, with 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.
- 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.
- With the above mentioned arrangement, it is rather difficult to overcome possible drawbacks related to a migration of the liquid downstream of the separating device as the system is put out of operation.
- Accordingly, 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.
- Within the scope of the above mentioned aim, 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.
- The above mentioned aim and objects, as well as yet other objects, which will become more apparent hereinafter, are achieved by 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.
- Further characteristics and advantages of the present invention will become more apparent hereinafter from the following detailed disclosure of a preferred, though not exclusive, embodiment of an apparatus for separating a two-phase flow into a plurality of partial flows, with a like liquid to gas ratio, which is illustrated, by way of an indicative, but not limitative example, in the accompanying drawings, where:
- Figure 1 is a schematic perspective view illustrating the apparatus according to the present invention;
- Figure 2 is a cross-sectional view, substantially taken through a vertical plane, illustrating the separating apparatus according to the invention; and
- Figure 3 illustrates a further cross-sectional view, substantially taken along the section line III-III of figure 2.
-
- With reference to the number references of the above mentioned figures, 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 aseparating 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 ofsaid body 1. - In said separating
chamber 2, in front of said inlet duct, a separatingwall 4 thereagainst is supplied the flow of theducts 3, so as to facilitate the separation of the liquid phase from the gaseous phase, is arranged. - Said separating
wall 4 defines abottom 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 separatingchamber 2. - The latter is provided with an
inner bottom region 10 for collecting therein the liquid phase and atop 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 separatingwall 4 and, advantageously, being evenly distributed with respect to the center of theapparatus body 1. - In particular, the
outlet tubes 20 are provided with a closedinner bottom 21 and a top opening 22, passing through the top cover of theseparating chamber 2. - The
outlet tubes 20 are provided, through their surface, with a plurality of longitudinally extendingslots 30 which are variously distributed and which, advantageously, are open toward the inner portion of theseparating 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.
- Thus, 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 invention, as disclosed, is susceptible to several modifications and variations, all of which will come within the inventive idea scope.
- Moreover, all of the constructional details can be replaced by other technically equivalent elements.
- In practicing the invention, the used materials, as well as the contingent size and shapes, can be any, depending on requirements.
