Definitions

  • the invention relates to a device for dividing a flowing liquid-gas mixture into several partial flows with predeterminable ratios of liquid to gas mass flow, consisting of a separation space arrangement having a liquid and a gas area with at least one feed line for the mixture and several outlets in the gas and / or liquid area discharge lines for the formation of partial gas flows combined from a gas partial flow and a liquid partial flow.
  • This known device for dividing a flowing liquid-gas mixture into several partial flows with predeterminable ratios of liquid to gas mass flow has proven itself in practice.
  • the object of the present invention is to improve the known device in such a way that the phases of the mixture are separated even with a very compact and free design. ' In particular, it should also be achieved that the number of partial flows can be increased significantly with the same size.
  • At least one unit arranged in the flow path of the liquid-gas mixture and consisting of a plurality of baffle elements, is provided in the separation space arrangement for reducing the momentum of the liquid-gas mixture.
  • baffle elements are preferably arranged in a tangled position within the impulse reduction unit, wherein baffle baffle elements can preferably consist of the components of a tangled fiber mesh, a wire mesh, a block of steel wool or the like or of an open-cell foam.
  • At least two different baffle materials forming the pulse reduction unit follow one another in the flow direction of the incoming liquid-gas mixture, the density of the material forming the respective pulse reduction unit preferably increasing in the flow direction of the incoming liquid-gas mixture.
  • a targeted pulse reduction can be achieved with surprisingly small-volume units.
  • the material forming the pulse reduction unit is fixed in a holder which is at least partially grid-like or perforated plate-like and in which the fixing of the material results from its inherent elasticity.
  • a holder which is at least partially grid-like or perforated plate-like and in which the fixing of the material results from its inherent elasticity.
  • the material claws in the openings of the holder in such a way that no additional holding elements are required.
  • the meeting of the pulse reduction unit and the feed line is preferably connected to a cross-sectional expansion.
  • This cross-sectional widening in the flow direction can be in front of or in the area of the pulse reduction unit.
  • the pulse reduction unit advantageously consists of a cylindrical block which is held in an at least radially permeable basket, a ring-cylindrical block or a combination of such blocks. Due to the extensive freedom in the concrete design of the pulse reduction unit, problem-free adaptation to different separation space arrangements can be achieved.
  • a separating space arrangement has a distribution space with a liquid area and an overlying gas area, the height of the pulse reduction unit arranged in the distribution room preferably being selected such that the liquid level is located within the pulse reduction unit. This allows a particularly smooth liquid level to be achieved because the incoming liquid enters the liquid area at a low speed within the pulse reduction unit.
  • the distribution space of the separating arrangement is an inlet space with a pulse reduction unit that expands the cross section with respect to the feed line upstream, which is connected to both the gas and liquid side of the distribution room.
  • the inlet space is expediently arranged at the same level or above the distribution space, and the two spaces are connected to one another via the pulse reduction unit.
  • a liquid / vapor mixture is blown into a separating arrangement 10 from below via a pipeline 14, the vapor content being approximately 0.15 to 0.40.
  • This liquid-gas mixture must be divided into partial flows, each of which has a predeterminable ratio of liquid to gas mass flow.
  • the feed line 14 is surrounded by a pulse reduction unit 11, which is designed as a cylindrical block and has a plurality of baffle elements 23 in a holder 12. These baffle elements are arranged in confusion, which has the consequence that the liquid particles entrained by the steam entering through the line 14 hit these elements, lose their momentum of movement and, by division and multiple deflection, get directly into the liquid reservoir 17, the level of which is identified by 22.
  • the vapor or gas portion of the inflowing mixture separated from the liquid reaches the gas region 18, which is practically free of liquid splashes or foam formation.
  • gas or steam enters the discharge lines 20 via the ends of the tubes open at the top and also via slots 21 gas or steam, and this gas or steam flow takes a defined amount of liquid in the area of the liquid supply 17, which enters the discharge pipes via the slots 21.
  • a feed pipe 14 for the liquid-steam mixture is guided centrally through the lower bottom wall in a cylindrical separation space arrangement 10, and the pipe socket located in the cylindrical container extends into the region of the upper ceiling wall 24 and goes straight into one shield-like transverse wall 25 over.
  • This transverse wall 25 forms, together with the ceiling wall 24, an inlet space 19 and a radial flow guide, which prevents the liquid phase from falling directly down into the liquid reservoir 17 and causing undesirable swirling and bubble formation, or entering the upper gas inlet openings and so leads to uneven distribution.
  • a pulse reduction unit 11 is provided, which for example consists of a plug-like structure made of stainless steel wool.
  • This pulse reduction unit 11 has the effect that the liquid-steam mixture arriving at different and in some cases very high flow velocities is calmed and evened out and already flows radially outwards with extensive phase separation, the liquid phase leaving the guide area downwards along the wall of the container flows and thereby arrives in a further, ring-cylindrical, pulse abutment unit 11 'resting on the container wall.
  • the gaseous phase flows radially inward with a sharp deflection to the discharge lines 20 arranged there adjacent to the feed connector.
  • the open free ends of the discharge lines 20 are preferably somewhat higher than the outer edge of the screen, which contributes to the fact that practically no liquid can be taken into these gas inlet openings.
  • Bores 26 are provided in the discharge lines 20 at different heights and preferably have a larger opening cross section with increasing altitude. Instead of these bores, a narrow, preferably axially parallel slot 21 can also be provided. Instead of a single slot, several partial slots can also be used.
  • the ring-cylindrical pulse reduction unit 11 also contributes to the fact that the liquid phase is gently introduced into the liquid supply 17 and thus prevents the liquid supply from being agitated or swirled, which is unfavorable for the function.
