Definitions
- the invention relates to a method for heat transformation by means of a vortex unit, in which a steam flow in particular Saturated steam flow in the vortex unit in a heated partial flow and in a cooled partial flow is divided and in the cooled partial flow condensation takes place.
- the invention is based, loss and thus the task Loss of efficiency, especially in condensing power plants reduce and also the use of heat for district heating Desalination plants to improve water extraction or the like.
- the steam enters approximately tangentially into a vessel that is pointing downwards tapered and its shape corresponds to an egg or a funnel.
- the Condensate is drained down.
- the circulation number with which the Steam flow in spiral eddies moving forward, the longitudinal axis of the curling unit is of greater influence.
- the device dimensions are to be designed for larger amounts of steam. Experiments can be used to determine whether the Schauberger unit is in use with the same flow direction for warm and cold partial flow or the vortex tube principle with the opposite direction of the outlet flow of the core and edge zone shows the better effect.
- condensation power plants it is from these preferably wet steam from the vacuum area, e.g. B. from 0.2 bar (ts ⁇ 60 ° C) at a condensation pressure of approx. 0.07 bar (ts ⁇ 39 ° C). This results in a pressure ratio of almost 3 for relaxation in the curling unit. This ensures a maximum ballast power of the existing turbine aimed at, the performance of which would only be restricted in the vacuum region.
- the vortex tube measurements show a remainder at the warm tube end Overpressure, whereas the expansion of the cold air portion to atmospheric pressure he follows.
- the remaining temperature of the hot current is essential depends on the extent to which this hot current when generating the Secondary steam is cooled. The heat is conducted through the hot current continuously.
- the aim is to have the same secondary vapor pressure at the respective vortex stages from, for example, 15 to 60 bar to get this Merging steam flows and possibly with the appropriate pressure level the input steam flow together to simplify the process to be able to continue.
- the steam flows of the different pressure levels after heat transformation must be coordinated.
- an im Countercurrent or a curling unit with the same flow direction the edge and core flow are used.
- the method according to the invention can also be used for district heating be used. Steam from waste heat, solar heat, etc. are generated, which is then at least partially at a higher temperature level is transformed into electricity or heat. Can also at Low-cost electricity a heat pump can be used.
- the process offers water extraction in hot, dry areas Possibility of depending on the relative humidity of the air cooled at night Air compression with subsequent expansion in the vortex tube the cold air flow cool down to below the dew point so that water condenses. Part of this Water can then be evaporated during the day via a burning mirror using solar heat be, the water pressure produced by a pump with the achievable Saturated steam temperature is to be coordinated. That from the secondary steam using a turbine The energy obtained is then stored on a battery and used at night Drive of the air compressor used. Maybe it can also be used at night Warm air flow can be used to generate steam and electricity.
- ⁇ 0.5 cold air share in the total flow is one Temperature spread around 90 ° C (+ 60 ° C to - 30 ° C) measurable.
- the cold air flow can be heated by heat transfer by 70 ° C to + 40 ° C, the Warm air content cools from + 60 ° C to -10 ° C. But even at -30 ° C it needs Cold current component too much compression energy and thus experiences too high Heating, which prevents the aforementioned heat transfer and useful work.
- FIG. 1 and Fig. 2 show basic sketches according to the invention Process working condensation power plants in which different Operating parameters are entered.
- the speed of rotation in the vortex unit can be a suction component produce. Such a suction force could have a supporting effect and the pressure loss reduce in the vortex unit. This allows a larger number of Vortex unit stages can be connected in series. This will be the one in the capacitor Reduce the amount of exhaust steam to be precipitated and thus the remaining amount to be removed Reduce heat loss.
