摘要： PURPOSE:To provided a hot sea water supplying device for desalting of sea water which can reduce the quantity of the heat energy required for heating by supplying the hot sea water obtd. by cooling the fresh water for cooling of the auxiliary machinery of an atomic reactor with a heat exchanger for the cooling water of the auxiliary machinery of the reactor to a sea water desalting device. CONSTITUTION:In a sea water desalting device 11, a piping 10 for suction of the sea water to be desalted is connected to a piping 8 for discharging of the hot sea water of a sea water heat exhanger 1 for cooling water of the auxiliary machinery of an atomic reactor. By this connection, part of the hot sea water which is discarded heretofore is sucked by a pump 9 into the device 11 and can be recovered of its heat. Here, an additional valve 15 is a valve for stopping the inflow of the hot sea water when the device 11 is stopped. By the above constitution, the used amount of the steam 13 used for the heater 12 in the device 11 is reduced; hence, this is highly effective for the reduction of the running costs required for desalting of sea water.

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.

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 effectively utilize air reservoirs for backwash as an emergency air source by providing by-pass pipes for reverse air flows between the air reservoirs for backwash and an on-site compressed air system side. CONSTITUTION:This compressed air device is composed of each air reservoir 4-6 for backwash, by-pass pipes 23 for reverse air flow, reverse flow valve 22, and pressure setter 24 which sends a signal for automatically opening the valve 22 upon detecting the abnormal pressure drop of an on-site air compressor 1. Since the valve 22 is opened and closed by means of the pressure-high and pressure-low signal of the setter 24, the valve 22 is closed at th time of normal operation when the pressure is high and is automatically operated only when the pressure of the compressor 1 abnormally drops. Since the pipes 23 are provided on the downstream side of a check valve 8 or directly connected with the air reservoirs 4-6, the air in the air reservoir 4-6 does not move to the compressor 1 side due to the valve 8 during the normal operation. Therefore, the air in the reservoirs 4-6 can be utilized effectively at the time of abnormality, since air can be made to reversely flow through the valve 22 only when the pressure of the system abnormally drops.
