Definitions

  • the invention relates to a device for the introduction of low turbulence Liquid into a liquid container that can be filled with the liquid and in whose filled state the liquid has a liquid level.
  • CO 2 high-purity carbon dioxide
  • Such carbon dioxide is usually stored in liquid form.
  • gaseous carbon dioxide is condensed by cooling and then fed to a pressure vessel in which the carbon dioxide is stored liquid under pressure. Since liquid carbon dioxide is regularly supplied or removed from this container, the container is generally not completely filled with liquid carbon dioxide. Rather, there is a gas atmosphere in the container above the liquid level.
  • the liquid carbon dioxide in the container should be as free as possible of any additives, such as such microbubbles.
  • the aim of the invention is to determine the purity of a liquid such as e.g. liquid carbon dioxide to improve in a liquid container.
  • a first flow body with a flow body top comprises parallel to the liquid level at the liquid level or runs in the vicinity of it, or in all directions at a flat angle Immersed liquid level and that in connection with a liquid supply line stands, which opens on the top of the flow body.
  • the to be fed Liquid flows in a flat film over the top of the flow body.
  • the Liquid to be supplied is laminar and practically without turbulence Liquid container located liquid supplied on the surface thereof, so that any gas bubbles still remaining in the supplied liquid easily can outgas.
  • turbulence prevents new gas bubbles from being introduced into the liquid. Accordingly
  • the main idea of the invention is to create such swirls as much as possible when introducing a liquid into the liquid container avoid.
  • the liquid to be supplied to the liquid container in the container Liquid is supplied from the surface, but not directly, but over the first flow body, the flow body top of which is completely or in parts at or near the liquid level Container is located.
  • the liquid to be supplied is first on the top of the flow body directed, distributed on this and consequently flows with reduced Speed almost parallel to the liquid level in the already liquid in the container.
  • the flow body can have a flat top of the flow body, which is at or near the level of the liquid.
  • the top of the flow body can also be curved flat and with their Dip the outer circumferential edges somewhat into the liquid at a flat angle.
  • the liquid feed line preferably opens centrally on the upper side of the flow body. In this way it is achieved that the liquid supplied distributed as evenly as possible over the top of the flow body and with lowest possible excess of kinetic energy already in the liquid container liquid is added.
  • the surface of the thin liquid film which allows for easy outgassing Microbubbles causes, greatly enlarged. It can also easily be one if possible central liquid supply to the flow body top can be ensured.
  • the bottom of its flow area is preferably only a little above the top of the flow body, see above that the flow rate of the liquid supplied between the lower edge of the flow surface and the flow body top as possible does not increase.
  • the collecting trough has the central one To supply the liquid to the flow body top to effect the second Property to serve as a buffer storage and with fluctuating inflow to the Sump to a uniform drain to the top of the flow body cause.
  • the drip pan is used to first catch the liquid to be supplied, before going over the edge of the tub and the adjoining flow area into the sump and over the sump to the top of the flow body flows.
  • the second flow body is preferably one in the operating state Device vertical axis rotationally symmetrical. This will cause the liquid in all directions evenly over the second flow body flows.
  • the flow area of the second flow body is viewed from the outside preferably convex.
  • the flow surface has the shape of a lateral surface of a Truncated cone.
  • the device also preferably has fastening means for one Liquid supply, which are preferably arranged so that the liquid supply ends above or in the drip pan.
  • the first flow body is preferably a first float, which is dimensioned that the flow body top in the floating state of the Device parallel to the liquid level at the level of the liquid or runs close to it or on all sides at a flat angle into the liquid level immersed.
  • the device with floating body carries the first floating body also the collecting trough and the second flow body wearing.
  • the first floating body is preferably dimensioned so that the Device can float on the surface of the liquid when the Liquid supply is attached to the float. That way ensures that the float is connected to the liquid supply constantly on the surface of those in the liquid container Liquid floats and the liquid supply also lifts when the Liquid level in the liquid container rises.
  • the attachment of the Liquid supply to the device is therefore a mobile or flexible Attachment.
  • the device comprises a second floating body which is in the operating state vertically displaceably connected to the first floating body, the sump and the second flow body carry and are dimensioned so that the collecting pan and the second flow body in the floating Condition of the device is above the liquid level.
  • the first floating body carries only the upper side of the flow body and can therefore be set very precisely so that the flow body top with floating floats exactly at the level of the liquid located.
  • the second floating body carries the remaining components of the Device and must because of its vertical mobility compared to first float can be measured only relatively roughly so that the Sump and the second flow body above the liquid level are located.
  • the second floating body is dimensioned so that the device floating on the surface of the liquid when the liquid supply is attached to the float.
  • the liquid container with a liquid level sensor and a Liquid drain can be provided with a flow regulator that with the Liquid level sensor is connected.
  • the flow regulator is in this case preferably a pump connected to a control device.
  • the device does not follow the liquid level in the liquid container, rather the liquid level in the liquid container by means of the liquid level sensor and the correspondingly regulated Pump controlled so that the liquid level is always at the level of the top of the flow body of the first flow body or in its vicinity.
  • the liquid level sensor can be located, for example, in the wall of the liquid container be arranged at the level of the top of the flow body.
  • a liquid container 10 shown in FIG. 1 is up to a liquid level 12 filled with a liquid 14.
  • To add more liquid to the liquid container To introduce 10 there is a riser pipe 16 in the container 10, the starts from an opening 18 on the underside of the container 10.
  • the riser pipe 16 has an outlet 20 near its upper end, on which a channel 22 is pivotally articulated. With its other, lower end 24 the opens Channel 22 above a device 30 for the introduction of low turbulence Liquid into the liquid container 10.

  • the device 30 has a second one above the collecting trough 36 Flow body 40. This is on the collecting pan 36 and on this to the Float 32 attached.
  • the second flow body 40 has one downwardly widening flow area 42, which is formed by a collecting trough 44 the top of the second flow body 40 goes out.
  • the device 30 is pivotable with the Channel 22 connected near its lower end 24.
  • the first flow body 32 designed as a floating body is dimensioned such that that he carries the entire device 30 with attached gutter 22 and with rising liquid level 12 floating in the container 12. Here he takes the gutter 22 with him.
  • the liquid container 10 has a for removing liquid Drain 48.
  • FIG. 2 shows an alternative embodiment of the device 30 from FIG. 1.
  • the alternative differs in the design of the flow body 32 '.
  • the Flow body 32 ' has a buoyancy body 50 on the upper side thereof flat plate 52 is attached, the top of which the flow body top 34 ' forms. Together with the buoyancy body 50, the alternative first forms Flow body 32 'a float.
  • This alternative design of the first flow body 32 ' has the consequence that its flow body upper side 34 ′ is not like the flow body upper side 34 with its edges falling flat below the liquid level 12, but rather runs parallel to this.
  • the buoyancy of the alternative first flow body 32 'must therefore be dimensioned precisely so that its flat flow body top 34 'if possible always exactly at the level of the liquid level 12 or only little goes over it.
  • Fluctuations in the immersion depth of the first flow body shown in FIG. 1 32 have the consequence that the circumferential radius of the above the Liquid level 12 located part of the flow body top 34 to or decreases.
  • the device 30 ′′ has a second floating body 54, which is displaceable in the vertical direction in the operating state with the first flow body 32 ′′ formed as a first floating body is.

  • Liquid to be supplied to the container 10 passes through the opening 18 on the Bottom of the container 10 in the riser 16 and rises to its outlet 20 on. Via the outlet 20, the liquid enters the channel 22, which as Feed to the device 30 is used.
  • the channel 22 is filled with steel wool to improve outgassing in the liquid to be dissolved gas and to brake the flow rate of the liquid in the channel 22.
  • the to be fed Liquid leaves the channel 22 at its lower end 24 and enters the Collecting trough 44 of the flow body 40. As soon as the collecting trough 44 is completely filled with liquid to be supplied, the liquid begins over the Overflow the edge of the collecting trough 44 and reaches the flow surface 42 of the flow body 40.
  • the liquid flows down over the expanding flow area 42 of the flow body 40 and passes from lower peripheral edge of the flow surface 42 in the collecting pan 36, flows to Center of the collecting pan 36 to the outlet 38 located there, from which the Liquid reaches the center of the flow body top 34 or 34 '.
