Abstract

The present invention relates to an apparatus (1) for separating a two-phase flow or stream into a plurality of partial flows with a like liquid to gas ratio, comprising a separating chamber (2) communicating with an inlet duct (3) for supplying a two-phase flow and defining a bottom region (10) for collecting the liquid phase and a top region (11) for collecting the gaseous phase. The main feature of the invention is that the apparatus (1) further comprises a plurality of outlet tubes (20) arranged in the separating chamber (2) and leading to the top surface of the separating chamber (2). <IMAGE>

Description

The The present invention relates to a device for separating a Two-phase flow or a two-phase flow in a plurality of partial flows with same liquid / gas ratio accordingly The preamble of claim 1. Such a device is made Document US-A-2 220 595.

Be known in refrigeration systems conventionally Devices for separating a two-phase flow or a two-phase flow into a plurality of partial flows or currents used with an equal liquid / gas ratio.

The mentioned above Device essentially comprises a separation chamber, to which a Wire for feeding the gas / liquid mixture leads, which is influenced by suitably designed elements which the flow so hinder that inside the separation chamber, a lower area to collect the liquid in this and an upper area for collecting the gas in this to be provided.

In said separation chamber are a plurality of outlet tubes or arranged lines, which is usual way Tubes include a plurality of longitudinally extending slots have, wherein the tubes in the interior of the separation chamber axially extend and lead to the lower portion selbiger.

With the aforementioned Arrangement, it is quite difficult to fix possible disadvantages, which with a migration of the liquid downstream of the separator, if the system except Operation is related.

Summary the invention

Accordingly The object of the present invention is to provide the above mentioned Problems encountered by a device for separating a Two-phase flow into a plurality of partial flows with the same liquid / gas ratio to disposal which always allows a constant ratio of liquid and to get gas.

in the Frame of the aforementioned Objective is a main object of the present invention It is to provide such a device that with a very simple design optimal operation at different Ensures operating conditions.

A Another object of the present invention is to provide such Device available to put that very reliable and is safe to operate.

Yet Another object of the present invention is to provide a Such device for separating a two-phase flow or a two-phase flow into a plurality of partial flows or currents with an equal liquid / gas ratio to disposal to put in a simple way using easily available elements and materials can be made and which beyond from a purely economic Position is very competitive.

The mentioned above Goal is achieved and the tasks as well as other tasks which Become more obvious in the following, be solved by a device for separating a two-phase flow in a plurality of partial flows with same liquid / gas ratio accordingly Claim 1.

Short description the drawings

Further Features and advantages of the present invention will become apparent below become clearer from the following detailed disclosure a preferred, although not exclusive embodiment a device for separating a two-phase flow in one Plurality of partial flows with the same liquid / gas ratio, which by way of an illustrative, but not limiting Example in the attached Drawings is shown, wherein:

1 Fig. 12 is a schematic perspective view illustrating the apparatus according to the present invention;

2 Figure 3 is a cross-sectional view taken substantially along a vertical plane illustrating the separation device according to the invention; and

3 another cross-sectional view, which is essentially along the section line III-III 2 taken.

description the preferred embodiment

With reference to the reference numerals of the above-mentioned figures, the device for separating a two-phase flow or a two-phase flow into a plurality of partial flows or flows having the same liquid / gas ratio comprises a device body 1 , of the preferably has a substantially cylindrical configuration, which in its interior a separation chamber 2 determined with an inlet tube for supplying a two-phase flow 3 communicating with the separation chamber, the tube being substantially radial to the fuselage 1 is arranged.

In the separation chamber 2 is in front of the inlet pipe a partition 4 arranged against which the flow from the pipes 3 is fed so as to facilitate the separation of the liquid phase from the gas phase.

The partition 4 defines a lower space 5 and an upper space 6 , which are designed to reduce the speed of the two-phase flow and to keep the free surface of the liquid stable in the separation chamber 2 is held.

The latter has a lower area inside 10 for collecting the liquid phase in this and an upper area 11 for collecting the gas phase in this.

The main feature of the invention is that a plurality of outlet pipes 20 is provided, wherein the outlet pipes beyond the by the mentioned partition 4 separated area and advantageously evenly with respect to the center of the device body 1 are distributed.

In particular, the outlet pipes 20 a closed inner floor 21 and an upper opening 22 on, passing through the top cover of the separation chamber 2 through rich.

In the outlet pipes 20 are through the surface through a plurality of longitudinally extending slots 30 provided, which are distributed differently and preferably to the inner region of the separation chamber 2 are open.

The device disclosed above, which a plurality of comprising upwardly projecting outlet pipes, always allows a constant ratio of discharged liquid and gas flow to provide, independently of possible minor inclinations with respect to the vertical line of the vessel axis.

The Thus disclosed device makes it possible, same liquid phase / gas phase conditions over the To provide outlet pipes, in contrast to the approaches according to the state the technique while at the same time a separate area between the inlet area the two-phase flow and the area from which the outlet pipes exit becomes.
