Definitions
- the present invention relates to a thermodynamic cycle apparatus comprising a working medium with a lubricant additive and an expansion machine for converting enthalpy in the working medium into mechanical energy.
- ORC Organic Rankine Cycle
- the working medium is brought to a working pressure by a feed pump, and it is supplied to it in an evaporator energy in the form of heat, which is provided by a combustion, a waste heat stream or other heat source available.
- the working fluid flows via a pressure tube to an expansion machine in which it is expanded to a lower pressure.
- the expanded working medium vapor flows through a condenser, in which a heat exchange between the vaporous working medium and a cooling medium takes place, after which the condensed working medium is pressurized by the feed pump and returned to the evaporator in a cyclic process.
- volumetric expansion machines also called positive displacement expansion machines be referred to, include one or more working chamber (s) and perform during an increase in volume of this working chamber (s) during the relaxation of the working medium work.
- These expansion machines are realized, for example, in the form of piston expansion machines, screw expansion machines or scroller expander.
- Such volumetric expansion machines are used in particular in ORC systems of small power class (eg 1 to 500 kW electrical power).
- ORC systems of small power class (eg 1 to 500 kW electrical power).
- volumetric expansion machines require lubrication by a lubricant in particular the piston or the mutually rolling profiles (flanks) of the expansion space and the bearings and the sliding walls of the working chamber. So it requires a lubrication of the bearings and the touching flanks.
- the lubrication of the high-pressure side and the low-pressure side bearings is accomplished via a respective lubricant supply.
- the lubricant is directed to the bearings, passes through the bearing and leaves the bearing via a connection to the low pressure side and enters the exhaust steam path. There, the liquid oil mixes with the exhaust steam and is transported to the condenser.
- Both bearings are approximately at the same pressure level, since the two bearings are connected to each other via a bore / pipe.
- the pressure level at the bearings is on the order of the pressure at the outlet of the expansion machine.
- US 5,329,771 A discloses an ORC system in which working fluid is branched between two pumps and supplied to hydrodynamic bearings for lubrication.
- thermodynamic cycle device with a working fluid with a lubricant additive; an expansion machine for converting enthalpy in the working medium into mechanical energy; a multi-stage pressure increasing device (for example, a feed pump) for stepwise pressurizing the working medium; means for branching off a portion of the working fluid between two stages of the multi-stage pressure booster; and means for supplying the diverted portion of the working medium to one or more bearing points of the expansion machine.
- the tapping of the multi-stage pressure booster for diverting a portion of the working medium has the advantage that the working medium with the lubricant is diverted directly from the multi-stage pressure booster at a suitable pressure level.
- thermodynamic size of the enthalpy of the working medium includes, as usual, the internal thermal energy and the volume work to be done ("pressure energy").
- the multi-stage pressure booster comprises a multi-stage pump, in particular a multi-stage centrifugal pump.
- the pressure booster stages have the same operating principle and are housed in a housing ("a pump").
- thermodynamic cycle device A development of the thermodynamic cycle device is that the means for branching a portion of the working fluid may include a branch, in particular a bore, between two stages of the multi-stage pump. This represents a simple practical realization of the means for branching.
- the means for supplying the diverted portion of the working medium to one or more bearings of the expansion machine may comprise one or more conduits.
- thermodynamic cycle device in the case of a multi-stage pump with two or more impellers, the means for branching off a part of the working medium in the conveying direction of the pump can be arranged between two directly adjacent impellers.
- the gradual increase in pressure of the working fluid can be exploited by means of the wheels and a part of the working medium (mixture of a working fluid and the lubricant) are branched off at a suitable location.
- thermodynamic cycle apparatus may further comprise means for discharging the working medium with the lubricant additive from the one or more bearing points, wherein the means for discharging the working medium may be in particular in fluid communication with an outlet of the expansion machine.
- the cycle device may be an organic Rankine cycle device and / or the expansion machine may be selected from the group consisting of a piston expansion machine, screw expansion machine, a scroll expander, a vane machine and a root expander.
- the working medium may be provided in the form of an organic working medium, wherein the working medium may in particular comprise or consist of a fluorinated working medium, such as fluorinated hydrocarbons, fluorinated carbons, fluoroethers or fluoroketones, and / or the lubricant, in particular Include or may consist of refrigerant oil, and / or wherein the lubricant content of the working medium can be between 0.1% and 10% by weight.
- a fluorinated working medium such as fluorinated hydrocarbons, fluorinated carbons, fluoroethers or fluoroketones
- the lubricant in particular Include or may consist of refrigerant oil, and / or wherein the lubricant content of the working medium can be between 0.1% and 10% by weight.
- thermodynamic cycle device can be part of a steam power plant.
- the above object is further achieved by a method of lubricating an expansion machine in a thermodynamic cycle apparatus, the cycle apparatus comprising the expansion machine, a multi-stage pressure booster and a working medium with a lubricant additive, and the method comprising the steps of: stepwise pressurizing the working medium with the multi-stage pressure booster device; Diverting a portion of the working fluid between two stages of the multi-stage pressure booster; and supplying the diverted portion of the working medium to at least one or more bearing points of the expansion machine for lubricating the bearings.
- the multi-stage pressure booster comprises a multi-stage pump.
- FIG. 1 exemplifies a lubrication system for an expansion machine according to the present invention.
- the working fluid will be diverted directly from the multi-stage feed pump at a suitable pressure level.
- the solution according to the invention advantageously combines the function of a condensate pump and the feed pump in a housing and makes it possible to remove liquid at a suitable location, this location (number of already passed stages) determining the pressure level of the withdrawn liquid.
- a special feature of these pumps can be used.
- the pressure increase in the multi-stage pumps takes place by a juxtaposition of a plurality of impellers, so that per stage a pressure increase of e.g. 1 bar takes place.
- the wheels are mounted on a shaft in a housing and each have the same diameter. Towards the shaft, an increase in pressure is observed in stages. Through a tap at a suitable point can now liquid, in the present case lubricant working fluid solution, are removed at the pressure level, which already has the appropriate pressure level. So it must be made no further increase in pressure of this fluid.
- FIG. 1 shows a schematic diagram of a thermodynamic cycle device according to the present invention.
- the thermodynamic cycle apparatus includes a multi-stage multi-impeller feed pump 1.
- the multi-stage feed pump 1 is supplied with liquid working fluid-lubricant solution, which solution enters the inlet 2 in the pump.
- the necessary for the lubrication of the bearings 9 of the expansion machine 5 mass flow is diverted directly at a suitable point 3 with a prevailing pressure level between two adjacent wheels and the bearings 9 are provided.
- the bearings 9 are supplied via the lubricant supply 4, wherein the lubricant passes through the bearings and is discharged via a discharge line / device 6.
- the discharge line / device 6 is in communication with the outlet of the expansion machine 5, which in turn is in communication with the condenser 7.
- both the lubricant supply 4 and the lubricant discharge line 6 can be integrated into the expansion machines 5 and need not be designed as a separate line, but can be part of the housing or the rotors.
- the exhaust steam and the lubricant pass to the condenser 7, from which the liquefied working medium lubricant solution is conducted to the bearing points 9 and to the evaporator 8 by means of a feed pump as described.
- the working fluid evaporates, but the lubricant remains liquid and serves for lubrication and sealing of the flanks of the expansion machine. 5
