Definitions

  • the present invention relates to a steam power plant withmém and flue gas cleaning plant, and a wastewater treatment plant for process wastewater and in particular the recovery of process water.
  • the invention further relates to a method for operating a steam power plant with cooling tower and flue gas cleaning system.
  • a steam power plant essentially comprises a fired boiler, a steam turbine, a water-steam cycle, a condenser, a cooling tower and a flue gas purification plant.
  • deionized water is used, which is produced in a demineralization plant using ion exchange resins.
  • the deionized water is vaporized in the steam generator and sent to the steam turbine where it is depressurized.
  • the released during relaxation energy is transmitted via a wave to the generator.
  • the expanded steam is then fed to a condenser and the liquid phase condenses.
  • an evacuation system is connected to the condenser which generates a vacuum when the steam power plant starts up in the condenser and maintains it during operation.
  • the vacuum increases steam turbine efficiency and removes non-condensable gases from the liquid stream.
  • the impurities and additives include, in particular, ammonia, calcium, magnesium, sodium, potassium, chlorides, nitrates, sulfates (sulfuric acid) and silica.
  • the working medium contaminated by impurities or additives must be discharged as process wastewater from the water-steam cycle, since the impurities are in direct opposition to reuse as a working medium in the water-steam cycle.
  • Ammonia serves as an alkalizing agent for conditioning the feedwater.
  • the addition of ammonia makes it possible to increase the pH of the working medium, which reduces the relative corrosion rate of the feedwater. Since the distribution coefficient of ammonia in liquids and steam differs, locally significantly increased ammonia concentrations can occur in system parts with evaporation and condensation processes.
  • Process wastewater accumulates at various points in the steam power plant. A large part of contaminated water is obtained in the form of blowdown from the boiler drums in the evacuation system. When starting up and shutting down, shortages (due to dosing of working medium) and multiple stocks (due to discharge of working medium) of the working medium must be compensated. Furthermore, process waste water is produced by taking water samples and leaks in the water-steam cycle. Due to the aforementioned loss of water, the water-steam cycle must be continuous with demineralized water
  • Dewatering for example, during operation from longer closed pipelines, in which condensate has accumulated. For this purpose, the relevant pipes are opened briefly and thus dewatered. In doing so, water is lost to the water cycle, which is recirculated by additional water (deionized water). must be led. Dewatering also occurs particularly frequently when starting and stopping the steam power plant, since, for example, when the steam power plant is shut down, the steam in the water cycle gradually condenses and the resulting liquid water must not stand in the plant components, in particular in the heating surfaces. When driving off, more water is dewatered from the water cycle than is refilled until no more water is added at the end.
  • the process wastewater from the water-steam cycle is returned, depending on the quality, back into the water-steam cycle, discharged into the cooling tower or the industrial wastewater system.
  • An exemplary state-of-the-art fossil-fueled steam power plant with 2x1050 MW, a natural draft cooling tower and a wet limestone flue gas cleaning plant, produces up to 100,000 tons of process wastewater per year during basic load operation, which has to be discharged into public waters. Almost half of this is accounted for by the cooling tower.
  • the object of the invention is therefore to specify a steam power plant in which the total water consumption of a steam power plant is minimized, the pollutant capacity in the remaining wastewater, in particular the wastewater of the flue gas cleaning plant, and the consumption of demineralized / demineralized water is minimized.

  • a process water can be supplied to the flue gas purification plant, and a process waste water can be diverted from it.
  • the flue gas cleaning system is connected to the cooling water circuit in such a way that the process water required for the flue gas cleaning can be removed from the cooling water circuit.
  • the flue gas cleaning plant is connected to a wastewater treatment plant comprising an evaporator for the discharge of process wastewater.
  • a purified process waste water can be generated by the wastewater treatment plant.
  • the invention is based on the consideration, on the one hand to use water from the cooling water circuit for flue gas cleaning, and on the other hand to clean the contaminated by the flue gas cleaning process wastewater by evaporation in Ab- water treatment plant, so that a clean process wastewater is produced.
  • the raw water demand of the steam power plant can be reduced by the amount of additional water required by the flue gas cleaning system.
  • Lower water consumption or optimized water treatment can also reduce chemical consumption, making the plant's environmental footprint more resource-efficient.
  • the distillate is of high purity and can be reused in the power plant. It is possible to introduce the distillate into the raw water tank or into the permeate tank of the demineralization plant. The heavily polluted wastewater from the flue gas cleaning is completely processed by the evaporation. The raw water requirement and the wastewater volume of the power plant are thus reduced.
  • the flue gas cleaning system is connected to the cooling water circuit after the cooling tower such that cooling tower drainage water is used as process water for the flue gas cleaning.
  • Cooling tower sewage is wastewater that is a major requirement in a power plant with a cooling tower as contaminated process water and is therefore always available. This reduces the total amount of wastewater, as the process water in the flue gas cleaning system is additionally thickened.
  • the thickening can also be considered disadvantageous depending on local guidelines and specifications or requirements, since the process wastewater in the flue gas cleaning plant is repeatedly thickened.
  • the salt and heavy metal load and the pollutant input through the flue gas cleaning in the process wastewater can be very high.
  • An improved and preferred embodiment of the fossil-fired steam power plant therefore proposes to supply the flue gas cleaning plant with a process water which is connected from the cooling water circuit upstream of the cooling tower and upstream of a cooling tower additional water treatment plant.
  • This process water has not yet been processed in the cooling tower auxiliary water treatment plant and is therefore untreated.
  • the advantage here is that the water is simply thickened in the flue gas cleaning system and therefore limits for chloride, sulfate and heavy metals can be easily complied with.

  • Cooling tower slurry is not used here, this can be thickened higher.
  • the additional amount of water for the cooling tower is reduced because less is slurried. This reduces the water consumption of the steam power plant.
  • the required purity of the gypsum produced during operation of the steam power plant in the cooling water circuit is not used here, this can be thickened higher.
  • the additional amount of water for the cooling tower is reduced because less is slurried. This reduces the water consumption of the steam power plant.
  • the flue gas purification system is connected to the cooling water circuit in front of the cooling tower with a cooling tower auxiliary water treatment plant, so that a prepared for use in the cooling tower cooling tower water can be used as process water for flue gas cleaning.
  • a prepared for use in the cooling tower cooling tower water can be used as process water for flue gas cleaning.
  • treated coolant additive water is used as process water This is simply thickened, which makes it easier to comply with limits.
  • precipitation with FeC13 inridgetumzusatzwassers the chloride content of the water is slightly increased. Since the cooling tower slurry is no longer used, it can be thickened. This reduces the amount of makeup water added to the cooling tower as it is less likely to drain. This reduces the water consumption of the power plant. This measure may also be necessary if the total volume of waste water discharged into the forerunner is fixed.

  • the wastewater treatment plant is still connected to the condensate purification plant, the evacuation system and the sampling for the introduction of contaminated process wastewater from the water-steam cycle in the wastewater treatment plant. All process wastewater from the condensate treatment plant is returned to the water-steam cycle via the wastewater treatment plant.

As boiler flushing is done with deionized water, the quality of the rejected process waste water is good.
  • the auxiliary boiler is also fed with deionized water, which is why the quality of the process waste water (blowdown) is high.
  • deionized water In the process wastewater of the auxiliary boiler, increased ion concentrations and contamination by iron particles are to be expected.
  • the demineralized plant Due to the recirculation of the condensate produced by evaporation in the wastewater treatment plant to the full demineralization plant, the demineralized plant has to process up to 75,200 tons per year of less deionized water in the exemplified steam power plant.
