摘要： PURPOSE: To provide a condensate filtration device capable of facilitating the utilizing of a by-pass of a part of the device and of facilitating the adjustment of a period of water-passing through a hollow fiber membrane and a device designing differential pressure by utilizing the by-pass of the part of the device. CONSTITUTION: In a double condensate purification system consisting of a condensate filtration device 3 and a condensate demineralizer 4, a plurality of filters 7 are arranged in parallel between an entrance header 5 and an exit header 6 and a differential manometer 12 and an equal differential pressure control valve 13 are provided to each of the series of the filters 7. Differential pressures of the filters 7 are different from each other in accordance with pollution degree of a hollow fiber membrane in a tower. However, an opening extent of the equal differential pressure control valve 13 is adjusted in accordance with a signal from the differential manometer 12 to apply a differential pressure so that differential pressure of each of the series of the filters is controlled at a constant level.

摘要： PURPOSE:To provide an apparatus for demineralization in which reverse regeneration is prevented without installing a tank for receiving mixed resins, a high regeneration ratio is obtained by regenerating separately a cation exchange resin and an anion exchange resin. CONSTITUTION:A cation exchange resin and an anion exchange resin in a demineralization tower 1 are sent to a cation exchange resin regeneration tower 2, where back washing is conducted, and separated into a cation exchange resin layer, mixed resins layer, and an anion exchange resin layer. The anion exchange resin layer is sent to an anion exchange resin regeneration tower 3 through an anion exchange resin outlet pipe 9 to be regenerated, while the mixed resins layer 12 is sent to the demineralization tower 1 through a mixed resins extraction pipe 6 to be preserved. The cation exchange resin is regenerated in the cation exchange resin regeneration tower 2. The anion exchange resin is returned to the cation exchange resin regeneration tower 2 through an anion exchange resin returning pipe 13 and mixed with the cation exchange resin to be washed for finishing. The resin is returned to the demineralization tower where it is mixed with the mixed resins preserved.

摘要： PURPOSE: To contrive to utilize energy effectively by a method wherein a heating means for heating the steam generated in a heating drum and a means for directing the heated steam from the heating means to the heating drum are provided, in the titled concentrator wherein a heating drum and an evaporator are connected to each other by a closed-loop piping.
CONSTITUTION: In a concentrator for a waste liquid, particularly for the ratioactive waste water in a nuclear power plant, the steam coming out from a gas-liquid separator 4 after being generated in the evaporator 1 is compressed to a desired pressure by a compressor 17. Due to the heat generated at the time of compression, the steam is converted into a superheated steam of a high temperature. The superheated steam is fed into the heating drum 2, where it gives heat to the waste liquid being circulated, so that a concentrating and heating operation is conducted continuously. Upon giving heat to the waste liquid in the drum 2, the superheated steam is condensed to a liquid, the condensate is fed to a condensate cooler 18, where it is cooled by cooling water to a target temperature for recovery and it is recovered through an outlet port 22 as water for the plant.

摘要： PURPOSE: To obtain a deaerator enabling the sharp reduction of equipment and keeping the same deaeration effect as the existing method by utilizing effectively Henry's law in mechanical deaeration.
CONSTITUTION: The deaerator is composed of a tank 1 opened to the air and a gaseous nitrogen supplying device 2. Gaseous nitrogen supplied from the gaseous nitrogen supplying device 2 is controlled to a specified flow rate by a flow rate control valve 3, is injected into the tank 1 from a gaseous nitrogen supplying header 4 to deaerate the feed water in the tank 1 by bubbling. The gaseous nitrogen in the vapor phase of the tank is discharged to the open air through a vent pipe 5 together with the supply from the gaseous nitrogen supplying device. By providing a down part to the vent pipe, the vent pipe is filled with gaseous nitrogen having smaller sp. gr. than the air, and the inflow of air is prevented.
