摘要： PURPOSE:To enable automatic and speedy cleaning of heat exchanger tubes of a condenser, by using a simple lightweight winch for moving a carriage, and positioning a cleaning head by an articulated type arm. CONSTITUTION:A carriage 118 set on a guide rail 111 is vertically moved by a wire rope 116 and a winch 115, whereby the vertical position of the carriage 118 is generally determined. Then, first to third arms are swivelled to adjust a guide port of a cleaning head part 300 to the position of heat exchanger tubes 21, and a vertical shaft is moved to press the tip of the guide port against a tube plate 1. It is thereby possible to clean the heat exchanger tubes 21 of a condenser automatically, easily and speedily, and the title device is made light in weight and low in cost.

摘要： PURPOSE:To have an effective utilization of an energy of cooling water heat exchanged with a hot gas and decrease a pump driving power by a method wherein a cylinder is divided into two pressure chambers with a sliding piston, a stage in which a cooling water is supplied to one chamber to discharge cooling water in the other chamber outwardly and another stage in which the water is supplied to a water spraying nozzle are alternatively carried out. CONSTITUTION:When a cooling water tank 5A is filled with a low cooling water and a sliding partition plate 10A is located at an upper part of the tank, if a cooling water outlet valve 7A and a discharging water inlet valve 8A are opened, a pressure within the tank 5A becomes a pressure in a heat exchanger 1, a hot discharged water is flowed into the tank by a cooling water discharging pump 3 to push down the partioning plate 10A and the low cooling water in the tank is flowed into the heat exchanger 1 through the valve 7A. The partioning plate 10A reaches the lower end and the valves 7A and 8A are fully closed. Then, when a cooling water inlet valve 6A and a discharging water outlet valve 9A are opened, the low cooling water is flowed into the tank 5A by a cooling water supplying pump 2, the discharged water in the tank is pushed 8 out of the system by the valve 9A, the partioning plate 10A reaches the upper end and the valves 6A and 9A are fully closed. When both systems A and B are used, the supplying and discharging of cooling water for the heat exchanger 1 can be substantially continuously carried out.

摘要： PURPOSE:To release a difference of thermal expansion caused by a variation of temperature and to increase the life and reliability of a device by a method wherein a low temperature fluid is flowed in opposition to a high temperature fluid in a space between elements of a heat exchanger in which several elements having a high temperature flow path limited by a pair of plates and a spacer are connected. CONSTITUTION:An element 6 is formed with a high temperature flow passage 5 limited by a pair of plates 1 and spacers 2. Each of the adjoining elements 6 pushes to each other a high temperature gas in an opposite direction and by the same force against uniform hot gas by a flowing-in and a flowing-out of hot temperature gas near both vertical ends 9 and 10 so as to endure the force. Therefore, there is no problem in view of a strength against a gas pressure applied inwardly against a clearance between the elements 6 to which a low temperature gas is flowed, i.e., a central part of a low temperature flow passage even if there is no specific supporting part. Except a junction between the hot temperature gas flowing-in part 9 and the flowing-out part 10, it is possible to endure a gas pressure passing within each of the elements 6 even with a displacement stopper 11 fixed to each of the curved portions 4.

摘要： PURPOSE:To enable basic units manufactured in a factory to be assembled on the sea by putting, side by side and banding together on the water surface, plural basic units which consist of plural concrete-made cylinders linked in the vertical direction, the inside of which are partitioned into the upper parts and the lower parts, and dead weights are stuffed in the upper parts, while the lower parts are made to serve as storage tanks. CONSTITUTION:Plurals concrete-made cylinders 1 which have the same size and shape are provided with linkage parts A so as to be linked in the vertical direction at the linkage parts A. A cylinder block 2 has linkage parts A and a bulkhead B which are the same size as that of the cylinder 1. A basic unit 3 is constituted by linking plural cylinders 1 and cylinders 2, and sand and pebbles C are stuffed in the upper part and compressed air D is stored in the lower part. Plural basic units 3 are supported by plural frames 4.

摘要： PURPOSE:To store a large quantity of cold thermal energy in a heat accumulating tank by suspending a container filled with water in the heat accumulating tank filled with antifreeze liquid and immersing a vaporizer of a freezer in the antifreezing liquid. CONSTITUTION:Refrigerant gas delivered by a compressor 2 is condensed by a condenser 3, and cools antifreezing liquid in a vaporizer 10 after going through an adiabtic expansion in an expansion valve 5. As the antifreeze liquid cooled in the vaporizer 10 descends through gaps between containers 11 and circulates in a heat accumulating tank 1 by convection, water in the container 11 is efficiently cooled and all of it become frozen to store cold thermal energy in the heat accumulating tank 1. In order to recover said cold thermal energy, a brine pump is operated. The antifreezing liquid is drawn by the brine pump 6 to enter a radiator 9 where it is heated by releasing the heat and returns to the upper part of the heat accumulating tank 1. As the ice in the container 11 is positioned higher due to a difference in the specific gravity from water, the temperature difference from the circulated antifeezing liquid becomes greater, thereby improving the heat exchanging efficiency.
