摘要： A desalination process for seawater, based on electrodialysis heats the collected seawater by solar heat collectors. The preheated seawater is passed through an electrodialyser which separates it into two parts, a diluted solution and a concentrated brine. The preferred preheating temperature lies in the range from 30 deg.C to 90 deg.C. The utilisation of solar heat reduces the power requirements for desalination and makes effective use of the solar heat.

摘要： PURPOSE:To lower an unburnt component in an exhaust gas without raising the temperature of a furnace by setting an amount of air of a sub air port provided between main air ports based on a flow rate of a jet flow of a burner and a spiral force of the burner. CONSTITUTION:In an air port through which air for combustion is blown in on the downstream of a burner 2 which makes a burning below a theoretical air for making up for the shortage thereof, sub air ports 4 each with a smaller diameter thereof than main air ports 3 are provided between the main air ports or at least one or more thereof are provided between the main air ports and side walls or at both thereof to build a furnace 1. Then, the sub air ports 4 are provided with a flow rate adjusting function, an jetting direction adjusting function and moreover, a spiral generation function. The distribution or adjustment of the air ports is performed in correspondence to a flow rate distribution of a burner jet flow, a direction of turning the uppermost stage burner or a product of the direction of turning and a flow rate of the burner flow rate. This enables the lowering of an unburnt component in an exhaust gas without raising the temperature of a furnace.

摘要： PURPOSE:To desalt or concentrate a fluid of high pressure and high concentration without reducing pressure and preventing the generation of scale by disposing a desalination chamber and a concentration chamber alternately and forming the flowing direction of both chambers opposite each other. CONSTITUTION:Cation selective permeable films and anion selective permeable films are disposed alternately between an anode plate 41 and a cathode plate 42. A chamber frame, consisting of a frame body 51 and a net 52 positioned between said cation selective permeable films and anion selective permeable films, and provided with liquid chambers working as desalination or concentration chambers inside and with its outer periphery formed in a round shape or a polygon of pentagon or more, is provided. The clesalination chambers and the concentration chambers are disposed alternately and the flowing direction of both chambers are formed opposite each other. As a result, desalination or concentration of a fluid of high pressure and high concentration can be carried out without reducing the pressure and generating scale.

摘要： PURPOSE:To prevent deposition of alkaline earth metallic salts in a membrane separation type water producer by adding an easy to water dissolve compound for alkali metals to raw water, and beforehand depositing and separating the alkaline earth metals in the raw water. CONSTITUTION:Raw water 12 is mixed with sterilizing liquid 15 which is pumped 14 from a sterilizing liquid tank 13, thence it is filtered via a pump 16 by a filter 17. The filtered raw water 12 is added to alkali liquid 19 of a material selected from easy to water dissolve salts such as oxide, hydroxide and carbonate of alkali metals from a tank 18 by way of a pump 20 and is fed to a settling tank 21. Here, alkaline earth metallic salts are settled and removed, after which the raw water is injected with acidic liquid 24 from a tank 22 by a pump 23, to regulate pH value and is fed to an electrodialysis tank not shown. According to such method, power consumption for electrodialysis is less required because the ion concn. in the raw water does not increase.

摘要： PURPOSE:To reduce greatly the consumption of heat and electic power by mainly heating the fresh water side of desalting intermediate stage in electrodialysis chamber in the manufacture of fresh water from sea water. CONSTITUTION:The sea water from the pipe line 1 is sent to the electrodialysis tank 4 by dividing it into two flow paths, a desalination side and a fresh water side, semi-desalted water comint through the fresh wate side desalting chambers 7 and 8 is extracted from the extraction pipe 14 and then heat-exchanged with heated fresh water in the heat recoverer 5C. Then, the semi-desalted water is heated by the heater 6 and then introduced into the third desalting chamber 9 to lower the electric resistance value of fresh water. The bline concentrated in the concentrating chambers 10-12 and by the diaphragm 13 is obtained from the pipe 3, and also fresh water is obtained from the pipe 2. In comparison with the conventional method in which the whole amount of the sea water is heated, this method reduces the heat quantity required to heat the sea water to approx. half, and also since only the fresh side where electric resistance value at the time of electrification is much greater is heated, the lowering of the resistance value can be greatly reduced and therefore the consumption of electric power can be greatly reduced.

摘要： PURPOSE:To preheat the sea water without being affected by weather and day and night by transmitting heat energy converted from solar energy by heat collector to the sea water through heat pipe. CONSTITUTION:When passing through the pipe 10 inside the heat accumulator 3 by the pump 8, the sea water is preheated and then separated into the fresh water 13 and the enriched sea water 14 at the fresh water-manufacturing apparatus 6,each of which is introduced into respective heat accumulators 3 and used for heating the heat accumulating substance 5. The heating of the accumulating substance 5 is made by the procedure in which solar energy is collected by the heat collector 1, and transmetted to the heat accumulator 3 by evaporation and condensation of heat medium housed in the heat pipe 2. When the supply of solar energy is stopped at night or rainy weather, the sea water 9 is heated by heat possessed by the heat accumulating substance 5. The heat possessed by the heat accumulating substance 5 is not released from the heat pipe because the heat transmitting action of the heat pipe is nonreversible.

摘要： PURPOSE:To accomplish efficient energy trapping with a simple equipment eliminating moving parts by means of a heat pipe empolying water or the like for working heat medium to transmit heat between the heat collector and the heat storage device. CONSTITUTION:A heat pipe 7 employing water or the like for the heat medium is provided between a heat collector 1 and a heat storage device 2. The heat pipe is so inclined upward from the heat collector 1 to the heat storage device 2 as to allow the heat medium condensed on the inside of the heat storage device 2 to flow to the side of the heat collector. This can prevents the heat transmission from the storage device 2 from the heat collector 1, thereby checking the dissipation at a low temperature. In this manner, efficient heat storage is possible.

摘要： PURPOSE:For effective heat recovery for molten slag while providing constant quality slag, slag is cooled in two chamber system so that molten slag from blast furnace is solidified while being transferred by conveyor in the slag solidification chamber, then dropped into the heat recovery chamber. CONSTITUTION:Molten blast furnace slag in the hopper 1 is poured in molds 12 on the conveyor 11 in the slag solidification chamber 2. Slag, while being transferred obliquely upward by conveyor 11 driven by gear 14, is cooled and solidified by air from the inlet 4 and dropped in the heat recovery chamber 16. High temperature conveyor 11 is cooled by air from the inlet 5 and used again to transfer molten slag. High temperature solid slag is cooled in the heat recovery chamber 16 by air from the air header 19. Both cooling air for heat recovery chamber and slag silidification chamber is heated to high temperature and dicharged from the outlet 7 to be effec tively recovered by the waste heat boiler 20.
