摘要： PURPOSE:To facilitate discharge of non-condensible gas for disturbing heat transfer in an absorber for an absorption refrigerator and to reduce pressure loss. CONSTITUTION:Vapor 4 generated from an evaporator is fed from above a tube group 11, spread to an entire absorber through a vapor passage 12, and absorbed to absorbent liquid scattered from an absorbent scattering unit 7 to outer surfaces of heat transfer tubes. A vapor fluidizing resistance can be reduced by an effect of the vapor passage 12. Non-condensible gas is discharged in a high efficiency by so straightening it by a vapor straightener 5 disposed on the passage 12 that a final arrival point of a vapor flow becomes a bleed port 10 to be used also as an absorption discharge port.

摘要： PURPOSE:To reduce a flowing resistance of vapor in an absorber device in an absorption refrigerator machine and to facilitate a discharging of non- condensed gas at the absorber device. CONSTITUTION:Vapor generated at an evaporator passes through a vapor flowing-in part 3 and further passes through a vapor flow passage 2 to occupy an entire interior part of an absorbing device. In concurrent with this operation, the vapor is absorbed by the absorbing liquid 5 dispersed from an absorbing liquid dispersion device 4 to an outer surface of each of heat transfer pipes. Flowing resistance of vapor can be reduced under an effect of the vapor flow passage 2 between a region of pipe groups of heat transfer pipes 1 closely arranged to each other and the wall surface. In addition, the vapor flow is regulated by a vapor flow regulator plate 9 arranged in the vapor flow passage 2 in such a way as a final reaching point of the vapor flow becomes a vapor extracting port 6 also acting as an absorption liquid discharging port or a gas extracting port 7.

摘要： PURPOSE:To provide diagnosis with high reliability by performing the diagnosis based on the detection outputs of the state and nature of apparatuses constituting fluid circulation facilities. CONSTITUTION:In the circulation line of the circulation facility 1 of an atomic power plant, for example, the steam boiled from the pure water by a reactor core 61 in an atomic reactor 60 is liquefied by a condenser 68 after driving a turbine 67, it is converted into the pure water by a condensate demineralizer 69, then it is preheated by a water feed heater 69 then returned to the atomic reactor 60 by a water feed line 64. The pure water is returned to the atomic reactor 60 by a re-circulation system 62, and the purified 63 pure water is guided to the line 64. The vibration of the re- circulation system 62 is detected by a vibration detecting device provided on the facility 1 as the vibration of the facility apparatus itself then analyzed and inputted to an abnormality judging device 2. The stuck particulate materials are peeled off by the abnormal vibration, the circulation water with the increased number of particulate materials is detected 72 by a particulate material counting device 22 via a sampling line 9, signal-processed 73, and inputted to the device 2. The device 2 judges an abnormality based on the threshold value level from fluctuation values.

摘要： PURPOSE:To increase the collection amount of fine amorphous particles and the diffusion speed of said particles into a resin, by preparing an ion exchange resin for a condensed water desalting device by oxidizing only the surface of a resin on the condensed water side thereof or only the vicinity of the surface. CONSTITUTION:After a cation exchange resin is received in an electrolytic cell 1 having a 1% Na2SO4 solution received therein, a DC power source 3 is connected to a platinum electrode 2 and the cation exchange resin is stirred for 3-4hr by a stirrer 4 while a constant current of 2 ampere is made to flow to the electrode 2. Subsequently, the cation exchange resin 4 is taken out of the electrolytic cell 1 to obtain the cation exchange resin oxidized only on the surface. This resin is enhanced in the collection amount of amorphous clad and increased in the diffusion speed of amorphous fine particles into the resin and the separation of the amorphous fine particles from the surface part of the cation exchange resin becomes easy and, therefore, the efficiency of removing impurities in condensed water is enhanced.
