Definitions
- the present invention relates to a method and a device for dewatering in a steam power plant.
- the present invention further relates to a steam power plant.
- Such a steam power plant usually contains one or more steam drums with associated evaporators, with which, in particular at different pressure levels, steam is generated, which can be fed to a steam turbine.
- Impurities in the water-steam circuit of the steam power plant must be removed.
- a concentration of impurities arises in the steam drum.
- Due to the removal of saturated steam from the steam drum remain non-volatile substances in the steam drum.
- These non-volatile substances are removed from the circulation by leaching.
- effluents and steam through drainages which contain no impurities, but still largely discarded and not used.
- the replenished deionate has high levels of oxygen and carbon dioxide which require degassing of the deionate, thus prolonging the startup time of the steam power plant. Furthermore, costs are incurred and the environment is burdened.
- US 419,895 A For example, a method of optimizing the useful content of a geothermal fluid is described.
- US 3 008 295 A concerns a steam power plant.
- the invention has for its object to enable a technically effective way of dewatering in a steam power plant, the burden on the environment should be low. In particular, no contaminated water should be released and it should be handled sparingly with the water.
- This object is achieved according to the invention with a method and a device for dewatering in a steam power plant, wherein according to a degree of contamination of a number of partial amounts of water a separate collection of the relevant partial amounts of water is performed.
- the object is also achieved with a steam power plant having a device according to the invention.
- the possibility is advantageously created to significantly reduce the waste water accumulation. As a result, environmental requirements are more easily met. In addition, less deionate must be refilled.
- the inventive method and the associated device is applicable both for steam power plants with and without steam drum (eg a forced-circulation boiler).
- a steam power plant without steam drum only eliminates the drain and / or subsequent cleaning.
- the advantage of the invention lies in particular in relation to an introduction of the drains directly into a condenser in that the condenser does not have to be used to absorb water or steam when the steam power plant is at a standstill. At standstill fall particularly large amounts of dewatering condensate, which are fed into the water-steam cycle.
- At least one steam drum is taken from an amount of water (e.g., drum slurry) and fed to a water treatment. This can be done a cleaning of a water-steam cycle of the steam power plant and a feed of the recovered, clean water.
- water e.g., drum slurry
- At least one superheater and / or one steam line a further quantity of water (for example, dewatering condensate or steam) is removed and fed to a storage container. It is thus ensured that water accumulated in these components, which can not be processed by the turbine, is recycled.
- dewatering condensate or steam for example, dewatering condensate or steam
- This additional amount of water can be supplied to the water-steam cycle of the steam power plant without prior water treatment, so that the accumulation of waste water can be kept small.
- the water taken from the steam drum is subjected to a first water-steam separation and the separated and concentrated water is fed to the water treatment.
- the separated clean steam and the further amount of water taken from the at least one superheater and / or the steam line is fed to a second water-steam separation. This can minimize the amount of water that needs to be cleaned.
- the water separated in the first or second water-steam separation is supplied to the storage tank. This water is clean and does not have to go on be recycled to be re-injected into the water-steam cycle.
- the vapor separated in the first and second water-steam separation is fed to a condenser.
- a return of the steam is given in a simple way in the water-steam cycle.
- the water contained in the storage tank is kept isolated from the ambient air.
- the storage container is therefore closed. An air ingress or air entry can not take place. As a result, no oxygen enrichment takes place in the water, whereby a complex degassing is avoided and a rapid startup of the steam power plant is made possible.
- a first embodiment of a dewatering device 1 according to the invention is shown, which is part of a steam power plant 2 for power generation.
- the dewatering apparatus 1 is sealed from the atmosphere to prevent air leakage into the water-steam cycle of the To prevent steam power plant 2.
- various components of the steam power plant 2 are connected by means of lines for the transmission of water or steam. Dashed lines indicate contaminated water lines, dashed lines indicate clean water lines, and solid lines clean steam lines.
- the steam power plant 2 includes one or more steam turbines 3, the steam is supplied via a superheater.
- a combination of the superheater and an evaporator with the reference numeral 4 is shown.
- the dewatering device 1 contains a tank, which is designed as a separator tank 5 for water-steam separation.
- An input of the separator tank 5 is connected via a line to an outlet of the evaporator / superheater combination 4.
- a first partial amount of water from the superheater is drained, contaminated water discharged into the separator 5 and relaxed to further concentrate the Abschlämmwasser and separate clean water in the form of vapor from the contaminated water.
- the separated in the separator 5 contaminated and further concentrated water is conveyed via a line in a reprocessing tank in the form of a Abschlämmtanks 21, and processed in a cleaning system or water treatment 6.
- the treated water can be supplied to a condenser 7 of the steam power plant 2 for further utilization.
- the separated in the separator tank 5 steam contains no impurities and is introduced into a tank.
- the tank 8 is a flash tank and condensing tank, which is connected to the evaporator / superheater combination 4 and is introduced into the drained from the superheater, clean water as a second partial amount of water.
- the tank 8 is held with a so-called pad steam at a slight overpressure relative to the environment, so that air or carbon dioxide is not added to the water in the tank 8.
- a water-steam separation wherein the Separated water is fed to a tank 9, which serves as a condensate storage tank.
- the separated steam is fed to the condenser 7 via a suitable conduit.
- the dewatering device 1 further comprises a tank 10, whose inlet is connected via a drainage line to a steam line 11 for supplying steam to the steam turbine 3.
- This steam line 11 can be dehydrated in particular by the arrival and departure of the steam power plant 2 by the water discharged during the drainage as a third partial amount of water to the tank 10 is supplied. The water occurring during this drainage is clean.
- the tank 10 is a flash tank and condensing tank in which a water-steam separation takes place.
- the separated, clean water is supplied to the tank 9 and the separated, clean steam to the condenser 7.
- the water condensate supplied to the tank 9 is cached under exclusion of air, in particular with the aid of auxiliary steam, and fed back to the water-steam cycle, if necessary, by being fed into the condenser 7.
- the introduced from the tanks 8 and 10 in the condenser 7 steam is condensed in the operation of the steam power plant 2 in the condenser 7.
- the connecting lines from the tank 8 and from the tank 10 to the condenser 7 are closed and the steam is cooled by a cooling water system of the steam power plant 2, condensed and the condensate fed to the tank 9.
- the water in the condenser 7 is pumped via a hotwell into the steam drum of the steam drum / superheater combination 4, and the steam produced is then fed via the superheater to the steam drum / superheater combination 4 of the steam turbine 3.
- the second tank 8 has been used to receive water from the steam drum / superheater combination 4.
- the tank 10 was used to receive water from the steam line 11. It is also possible to supply both the water from the steam drum / superheater combination 4 and the water from the steam line 11 to a common tank, in which then a water-steam separation can be made.
