Definitions
- the invention relates to a method for compressing the working fluid in the water-steam combination process in multi-stage turbocompressors with intermediate cooling in the individual compressor stages by adding a freezer to the working fluid.
- Such a technical solution is required for the production of energy by means of water-steam combination processes.
- the object of the invention is therefore to provide a technical solution by means of which the shortcomings of the known prior art can be overcome.
- a technical solution is required which is suitable for efficient intermediate cooling of the working fluid during the compression step and thus for the greatest possible reduction in the compressor drive power.
- the object is solved by the features of claim 1. Preferred design variants are described in the subclaims.
- the intermediate cooling is carried out in the individual stages by adding a coolant to the working fluid.
- finely divided water is used as a coolant, which is obtained by spray-atomizing water into micro-water drops.
- the individual micro water drops have diameters of less than 50 ⁇ m, preferably between 2 and 20 ⁇ m.
- the coolant in the form of water mist is added directly to the working fluid in at least one compression stage, the coolant passing into the physical state of the working fluid during the compression process.
- the coolant is preferably added to the working fluid in an amount such that the thermodynamic equilibrium is maintained.
- the evaporation of the coolant takes place along the saturation line.
- an immediate increase in the working fluid mass flow is brought about.
- several desirable technical effects are achieved at the same time.
- the temperatures of the compressed working fluid and apparatus technology are reduced.
- the mass flow through the compressor is increased and a reduced compressor output is addressed.
- the steam turbine working on the same shaft can thus deliver an increased net power.
- the coolant is obtained from the liquefied working fluid of the WDK process in the form of water vapor condensate.
- the thermal energy required for the evaporation of the plasticizer during compression is taken from the compression system, consisting of a turbocompressor and working fluid, which leads directly to a reduction in the temperatures of the apparatus and media.
- the mass flow of the working fluid in the turbocompressor can be made variable by the controllable addition of cooling agent components to the individual leg stages.
- Figure 1 is a schematic sectional view through a turbocompressor with identification of the proportion of working fluid and coolant at the entrance to the turbocompressor.
- FIG. 2 shows a diagram for characterizing the course of the coolant portion in the total mass flow of working fluid and coolant over the individual stages of a 13-stage turbocompressor.
- the relaxed steam leaving the steam turbine is fed according to FIGS. 1 and 2 in a WDK process for recompression to a turbocompressor arranged on the common shaft.
- the turbocompressor has 13 compression levels. Before the working fluid enters the turbocompressor, the working fluid is added in the ratio: 1 part by weight of working fluid: 0.15 part by weight of coolant.
- the coolant consists of a water spray that is obtained by atomizing water vapor condensate. The diameter of the individual drops of the water spray is less than 25 ⁇ m.
