摘要： PURPOSE:To prevent adhesion of a marine organism without using chemicals and heavy metals, by a method wherein sea water, in which is irradiated with ultraviolet rays by means of a different system to sterilize adherent plankton in sea water, is caused to flow to a ball circulating system. CONSTITUTION:A system, in which water is fed through amain pipe inlet system 2 by means of a valve 12, is connected through an ultraviolet ray treating device 13 to the portion on the downstream side of a valve 8 on the inlet side of a ball circulating pump 6. Further, the system is connected from the portion on the upper stream side of a valve 9 on the outlet side of the ball circulating ball 6 through a bypass valve 14 to the upper stream side of the valve 8. When a ball is not circulated, the valve 8 is closed, water pumped up with the aid of a pump 6 enters an ultraviolet ray treating device 13 through the valve 12 for sterilizing treatment. After passage of water through the pump 6, the water is branched into a system subsequent to the valve 9 and a system of the valve 14, and outgoes to main pipes 2 and 4. This constitution prevents adhesion of a marine organism to a ball circulating system, and enables prevention of the occurrence of function deterioration of a ball washing device.

摘要： PURPOSE:To permit creation of environment where aquatic living matter is hardly stickable and survivable over a wide range with fewer light sources, by providing reflectors which reflect the light generated from UV light sources and project the reflected light to the parts of dead angles from the light sources. CONSTITUTION:The UV light is projected to the systems of a heat exchanger which uses sea water or river water as its cooling water or a structure which is in constant contact with the sea water or river water in order to prevent the propagation of adhesive contaminating organism. The reflectors which reflect the light generated from the UV light sources 1 and project the reflected light to the parts of dead angles from the light sources 1 are provided at this time. The reflectors are constituted of polygonal polyhedral reflecting cylinders 6 which rotate or are revolved by external driving source. As a result, the environment where the aquatic living matter is hardly stickable and survivable is created by the fewer light sources.

摘要： PURPOSE:To attempt to regenerate a condenser within a short period of time and reduce the shutdown period of a plant by cutting both ends of the main body of a condenser and a fine tube, dividing the tube nest in the direction of the tube length to disassemble the same, removing an internal structure, and loading a tube nest for replacing a all titanium tube having at its both ends a tubular plate and a short drum. CONSTITUTION:A fine tube 13 is cut at its intermediate portion as shown by a fine tube cutting part 22. A drum 4 is cut at both ends as shown by cutting portions 20 and 21. The fine tube 13 is pulled out horizontally toward right and left in a state where it is formed integrally with a water chamber side tube plate 8 and a flashing side tube plate 31, and removed. In a new tube nest 50, a water chamber 32, a water chamber cover 33, and a short drum 35 are formed as an integral structure, and a short drum 34 is mounted on the water chamber side tube plate 30. Further, in a drum 38 to be added to the drum 4 to commensurate with increased part of the tube length of a titanium fine tube 36, a drum expanding and contracting joint 39 absorbing the difference in elongation between the titanium fine tube 36, and the drum 4 is integrally assembled with a short drum 40, and the joint 39 is welded to the drum 4 to be secured thereto so that the renewed tube nest 50 can be easily fitted. On the tube nest 50 pulled into the drum 4 are finally mounted with blocking plates 42 and 43.
