Definitions

  • the invention relates to a device for cooling liquid or gaseous media.
  • Low-boiling liquefied gases can only be kept liquid by means of particularly good insulation of the storage tanks and the pipelines. Even the slightest heat or frictional heat can lead to partial evaporation, depending on the boiling state.
  • the boiling bubbles collect, except in the headspace of the storage container, e.g. also in vertical pipe bends. These so-called gas cushions in the supply line lead to disruptions at the sampling point when a reproducible dosing of the liquefied gas is required. It is easy to see that due to the density difference between the gas and the liquid, different amounts flow through an opening of the same size at equal time intervals. In order to have reliable pure liquid in front of the dosing, it is necessary to subcool the liquefied gas with respect to its respective boiling state.
  • Such supercooling can be accomplished, for example, by cooling the liquid coolant isobarically by means of an electric cooling unit so that no partial evaporation occurs during the circulation in a loop system due to heat radiation and friction losses.
  • an electric cooling unit so that no partial evaporation occurs during the circulation in a loop system due to heat radiation and friction losses.
  • the necessary aggregates are very expensive to buy and operate due to their high power requirements.
  • the device comprises a heat exchanger through which the liquid nitrogen to be cooled flows, which is arranged in an insulated container.
  • the heat exchanger is designed as a cooling coil, to which a float-operated lever valve is connected, which maintains a container surrounding the cooling coil bath of liquid nitrogen.
  • a gas outlet valve is provided, which ensures that the pressure in the container corresponds to the ambient pressure.
  • a disadvantage of this embodiment is that the bandwidth of the temperature setting is very narrow.
  • the invention is therefore based on the object to provide a device for cooling fluid media, in particular for subcooling liquids, with the simple way a high bandwidth of the temperature setting can be achieved.
  • a device for cooling of liquid or gaseous media with an arranged in an insulated container heat exchanger, which is flowed through by the medium to be cooled and which is accommodated in a bath of a cooling medium, with a in the interior of the isolated Container at an expansion organ ausmündenden pressure line for the cooling medium and with a equipped with a pressure control valve for adjusting the pressure in the container outlet line for the cooling medium.
  • the temperature of the cooling medium drops due to the Joule-Thomson effect.
  • the height of the pressure drop occurring during the expansion is determined by the pressure of the supplied cooling medium and the freely adjustable pressure holding value at the pressure control valve in the output line. Together with the additional parameter of the temperature of the supplied cooling medium before the relaxation can thus be set in theissermediumsbad a predetermined temperature.
  • a forced cooling such a gaseous or liquid medium can be cooled by heat exchange with thedemediumsbad, only care must be taken that the temperature of thedemediumsbades inside the container is not so low that the guided through the heat exchanger medium freezes.
  • the pressure line passes through a device for controlling the temperature of the cooling medium in front of its mouth on the expansion element.
  • a device for controlling the temperature of the cooling medium in front of its mouth on the expansion element.
  • the cooling medium already has a particularly low temperature before the relaxation.
  • a device for determining the level of the cooling medium bath is expediently provided, which is operatively connected to a arranged in the pressure line for the cooling medium blocking member. Falls below a predetermined level height, the blocking member of the pressure line opens and liquid cooling medium flows after.
  • the device for determining the filling height is a float-controlled lever valve.
  • float-controlled valves are often unreliable in practice, since the density of the high-boiling liquid in the container, and thus the buoyancy for the float, often insufficient to close the valve. In addition, the density difference between liquid and gas near the critical point is becoming smaller and smaller.
  • a device for detecting the temperature of the cooled medium is provided, which is operatively connected to the pressure control valve.
  • the pressure at the pressure control valve and thus the temperature of the cooling medium bath is set in this embodiment of the invention continuously in response to a desired temperature of the treated medium.
  • a preferred cooling medium is carbon dioxide. Due to its physical properties, carbon dioxide makes it possible to adjust the temperature of the cooling medium bath by adjusting the pressure in a wide range between +10 ° C and -55 ° C.
  • the device according to the invention is particularly advantageously suitable for subcooling, ie for cooling to a temperature well below the boiling point of the cryogenic medium used, for example liquid carbon dioxide.
  • subcooling in particular cavitation effects can be reduced in piston pumps.
  • the yield i. E. the proportion of snow compared to the proportion of generated carbon dioxide gas increase.
  • FIG. 1 schematically illustrates an embodiment of the device according to the invention.
  • the device 1 comprises a closed container 2 with a lid 3 with thermally insulated walls. Inside the container 3, two cooling coils 4,5 are arranged.
  • the cooling coil 4 serves to cool a liquid or gaseous medium, which is led into the container 3 via an insulated feed line 7 and leaves the container again via an equally insulated discharge line 8.
  • the cooling coil 5 is used for subcooling of liquid carbon dioxide, which is brought via an isolated and pressure-resistant carbon dioxide feed line 9 from a carbon dioxide supply tank, not shown here, for example, a low pressure or medium pressure tank.
  • an expansion valve 11 is connected, which is actuated by a float 12.
  • a valve 11 relaxation member which is located for example in the region of the inlet of the supply line 9 in the container 3, are introduced into the container .
  • the float control and other measuring devices may be provided for level measurement, which are operatively connected to the expansion valve 11, and in particular when using the Carbon dioxide near its critical point are more appropriate.
  • an exhaust pipe 14 is provided for the discharge of gaseous carbon dioxide.
  • a pressure-holding valve 15 is mounted, which keeps the pressure in the exhaust pipe 14, upstream of the pressure-holding valve 15, and thus in the container 3, to a predetermined value constant.
  • the pressure-maintaining valve 15 is in data communication with a temperature measuring device 16, which measures the temperature in the discharge line 8 immediately after it leaves the container 3.
  • the pressure of carbon dioxide in the carbon dioxide feed line. 9 either corresponds to that of the supply tank or it is interposed in the carbon dioxide feed line 8 means for increasing the pressure.
  • the expansion valve 11 is constructed so that in the presence of a pressure difference between the carbon dioxide feed line and falling below a predetermined level of the level 17 liquid carbon dioxide flows into the container 3.
  • the relaxing liquid carbon dioxide evaporates partially and is discharged via the exhaust pipe 14.
  • the unevaporated portion of the incoming carbon dioxide forms the cooling coils surrounding the 4.5 bath 18.
  • the pressure-holding valve 15 can be regulated in the interior of the container 3 and thus the pressure drop occurring during the outflow of carbon dioxide. Due to the Joule-Thomson effect, the relaxation of the liquid carbon dioxide leads to a drop in the temperature of the liquid carbon dioxide flowing into the container 3. For this reason, the temperature of the liquid carbon dioxide in the container 3 is lower than that of the liquid carbon dioxide in the carbon dioxide feed line 9. With a suitable choice of the pressure and the temperature in the carbon dioxide feed line 9 and the pressure in the container 3 so it is possible to precisely set the temperature of the bath 18 within a range between + 10 ° C and -55 ° C.
  • the temperature of the cooled medium is continuously measured by means of the temperature measuring device 16, so that the control pressure at the pressure-holding valve 15 can be regulated as a function of the measured temperature to a desired value or course.
  • the height of the level 17 by means of the float 12 and the controlled with this functionally connected expansion valve 11. If the water level drops, the expansion valve 11 is opened and liquid carbon dioxide flows out of the carbon dioxide feed line 9.
  • the medium introduced via the supply line 7 emits heat to the carbon dioxide bath 18 in the container 3 on its way through the cooling coil 4 and leaves the container 3 via the discharge line 8 in a cooled manner.
  • the medium to be cooled becomes, with a sufficiently dimensioned design of the cooling coil 4, cooled to approximately the temperature of the bath 18.
  • the device 1 according to the invention thus operates completely independent of external energy. Due to the wide range within which the temperature of the bath 18 in the container 3 can be adjusted, the device according to the invention is suitable for cooling a large number of liquid or gaseous media, for example from the pharmaceutical or food technology sector.
  • the device 1 is also suitable for supercooling of liquid carbon dioxide, wherein the separation of the two cooling coils 4 and 5 allows the setting of independent temperature and pressure conditions in the supply lines 9 and 7.
  • the liquid carbon dioxide used as a cooling medium can be removed from the stream of carbon dioxide to be supercooled.
  • the liquid carbon dioxide 9 introduced in the carbon dioxide feed line 9 has a pressure of 20 bar and a temperature of -25 ° C. After passing through the cooling coil 5, which, however, only serves for pre-cooling and on the achievable temperature value of the bath 18 has no influence, and the subsequent exit on the expansion valve 11, the carbon dioxide to a pressure of about 5 bar, the set target pressure at the pressure holding valve 15th corresponds, relaxed. This reduces its temperature to -50 ° C.
  • a portion of the carbon dioxide evaporates and is discharged via the exhaust pipe 14 as soon as the pressure in the container exceeds a value of slightly more than 5 bar - ie a pressure at which the cooled to -50 ° C carbon dioxide in the container 3 just barely liquid - exceeds ,
  • the non-evaporating in the relaxation part forms and continuously adds the bath 18 of liquid carbon dioxide, the temperature is therefore also -50 ° C.
  • Cooling energy is taken from the bath 18 made of liquid carbon dioxide by this partially evaporated and flows off via the exhaust pipe 14 irreversibly into the open air.
