摘要： PURPOSE:To provide a facility and method for water treatment in a combined plant wherein structure and operation are simple and operating cost can be saved by utilizing air extracted from a compressor. CONSTITUTION:A compressor 36 of a gas turbine 1 is connected to a condensate and feed water system of an once-through boiler 10 through an air extraction feeding pipe 3. As a result, by forcing the air extracted from the compressor 36 into the condensate and feed water system, the density of oxygen dissolved into the water of the system is maintained at a predetermined value, thereby preventing iron from dissolving in the water or from being corroded. Consequently, only be connecting the compressor 36 to the condensate and feed water system through the pipe 3, additional devices of a plant such as a conventional water treatment device is not required and hence devices and operation can be simplified and operating cost can be saved.

摘要： PURPOSE:To reduce the pressure loss caused by a filter, by giving an electric charge to the impurities contained in oil and then collecting these impurities by a filter. CONSTITUTION:An oil 1 to be treated in poured into an electrostatic oil cleaning device through an inlet 2, and thus the impurity contained in the oil are electrified at a high voltage electrode 3 to which the high voltage is applied via an insulator for high voltage plus a charging part opposite to the electrode 3 and consisting of an earth electrode 4. The electrified impurities are led to a filter collecting part 6 comprising a rapped filter. As the fiber diameter is extremely fine, a strong electric filed is produced at the rapped part when the electrified impurities get near the rapped part. Then, the impurities in the oil are attracted to the rapped area by the gradient force caused by the above-mentioned electric field to be collected there. While the oil is cleaned and discharged through an outlet 7. Thus a surface filtering system that collects the impurities at the area of rapping becomes available to reduce the pressure loss on the filter surface.

摘要： PURPOSE:To prevent the erosion of turbine blade owing to the scale of iron oxide from a boiler, in a circuit which recovers a steam generated from the boiler of a thermoelectric power plant to a condenser by a pipeline and a valve, by disposing a bypass circuit in parallel with the valve. CONSTITUTION:A steam generated from a boiler 1 bypasses a turbine 9 via a main steam pipe 2, and flow rate thereof is controlled by a main steam pipe warming valve 4 via a bypass pipe 3 thereafter. Moreover, the steam is cooled by a desuperheater 5, and is recovered to a condenser 10. And a condensate is returned to the boiler 1 by a feed water pump 13, after it is supplied to a deaerator 12 by a condensate pump 11. In this construction, a scale blow valve 15 and its front valve 14 and rear valve 16 are disposed in parallel with the valve 4. And the generated steam containing the scale of iron oxide from the boiler 1 is discharged to the condenser 10 by the valve 15. After that, the circuit is changed to the side of the valve 4 and a turbine governor 8 is opened, hen the turbine 9 is admitted with initial steam and speeded up.

摘要： PURPOSE: To prevent previously the deterioration of desalting performance by feeding only a cation exchange resin and anion exchange resin which are obtained by removing the inactivated resin out of the ion exchange resin subjected to the regenerating treatment into the inside of a desalting tower in the prestage of raw liquid treatment.
CONSTITUTION: An acid reagent is charged into the regeneration tower 8 through a reagent passing means to subject a cation resin 103 to the regenerating treatment. An alkali reagent is charged into the second regeneration tower 15 through the other reagent passing means to subject an anion resin 101 to the regenerating treatment. After the above-mentioned regenerating treatment of the cation resin 103, a stop valve 12 of a takeout pipe 11 for the cation resin is opened to take out the cation resin 103 out of the first regeneration tower 8 and the cation resin 103 is fed to a storage vessel 18 for an ion exchange resin through the take out pipe 11 and stored therein. On one hand, the anion resin 101 taken out from the second regeneration tower 15 is stored in the storage tank 18.

摘要： PURPOSE:To remove silica and hydrogen sulfide contained in geothermal water, by constituting a geothermal power plant to comprise an alkali injecting means for injecting an alkali, a means for absorbing hydrogen sulfide by way of chemical reaction, and a silica separating means for removing silica contained in geothermal water. CONSTITUTION:Hydrogen sulfide contained in steam is absorbed by injecting an alkali 2 into steam-containing geothermal water drawn up from a production well and mixing them sufficiently in a mixer 3. Then, the geothermal water is introduced into a multi-stage flash type heat exchanger 4. Hot water 1 is removed of incondensible gas containing hydrogen sulfide and carbon dioxide gas in a first-stage evaporation chamber 5, and then carried into the next evaporation chamber 5. Thus, the temperature of hot water 1 is lowered gradually through successive exchange of heat in the evaporation chambers 5. In a hydrogen sulfide absorbing means 13, hydrogen sulfide contained in the hot water 1 is absorbed by way of chemical reaction, and at the same time, pH of the hot water 1 is lowered. Then, silica sticks as scale in a silica separating means 17, and this sticking of silica is promoted along with lowering of pH and the temperature of hot water 1.
