Abstract: An activated carbon manufacturing system can efficiently heat a wood material or carbide to promote a drying process, a carbonization process and an activation process in manufacturing activated carbon, and can reduce the environmental load involved in the manufacture of activated carbon. Specifically, a drying process of a wood material is achieved by heating the wood material with saturated steam at an appropriate temperature, and an initial carbonization process of the wood material is achieved by heating the wood material with superheated steam. Therefore, the wood material can be heated with high heat transfer efficiency, so that the heat loss can be reduced, and neither a drying device nor a first carbonizing device produces a gas containing a harmful constituent in the heating processes, so that the adverse effect on the environment can be reduced.

Abstract: Disclosed is a method and apparatus for recovering rare metal, which separates and collects rare metals by making use of chemical actions in an efficient combination of adsorption and separation, thereby reducing work load and improving work safety. The method for recycling rare metals includes a leaching step in which a rare metal of palladium, platinum, and rhodium is mixed with hydrochloric acid into a hydrochloric acid mixture, which is then stirred at one atmospheric pressure or lower at a temperature from 50 to 90 degrees Centigrade. The vapor resulting from the stirring is condensed, and the hydrochloric acid resulting from the condensing is fed back to the original hydrochloric acid mixture to produce a hydrochloric acid leaching solution. The hydrochloric acid leaching solution produced in the leaching step is used to collect the rare metals.

Abstract: An absorber having a shell, wet tubes and cooling fluid supply and collection portions. Partition walls divide the shell into at least three zones. The wet tubes are disposed parallelly in the shell, passing through the partition walls. The opposite open ends of the wet tube locate in the uppermost and lowermost zones of the shell, respectively. The cooling fluid supply portion communicates with the open end of the wet tube to supply a cooling fluid thereto. The cooling fluid collection portion communicates with the other open end of the wet tube and discharge it outside. A gap is formed between the wet tube and the partition walls facing the intermediate zone. The cooling fluid continuously flows in the wet tubes, while supplying the liquid working fluid to the uppermost zone so as to flow down from the gap. The liquid working fluid flows through the gap to the zone locating below the intermediate zone and is discharged outside.

Abstract: Tubular heat transferring members are disposed in a shell. A kind of fluid passes through the heat transferring members, while the other kind of fluid flows around the heat transferring members in the direction perpendicular to the flowing direction of the former fluid, to make a heat exchange between these fluids through the heat transferring members. No packing member is needed to ease restriction in pressure applied to the fluid, improving the heat exchange efficiency. There is no occurrence of leakage, improving reliability. The opposite end portions of the heat transferring members serve as an inlet to the inside of the heat transferring members and an outlet therefrom and there is no opening formed in the intermediate portion of the heat transferring members without wasting material in a blanking process for the heat transferring members, thus providing an economic effect.

Abstract: A condenser comprises at least one heat transferring face formed of a plate-shaped material. Change of phase of a low temperature fluid from a liquid phase to a gaseous phase is made by causing a high temperature fluid and the low temperature fluid to flow on opposite surface sides of the heat transferring face, respectively, so that flowing directions of the high and low temperature fluids are perpendicular to each other, to make a heat exchange. There is provided at least one condensate discharging trough portion having a first groove portion formed on a surface of the high temperature fluid side of the heat transferring face so as to extend in an oblique direction to a flowing direction of the high temperature fluid by a prescribed angle. The condensate discharging trough portion is capable of receiving condensate of the high temperature fluid, which is generated on the heat transferring face to flow down in the flowing direction of the high temperature fluid.

Abstract: Local heat transferring zones are provided on a heat transferring face. The zones have prescribed patterns of irregularity, which are different from each other. Resistance corresponding to the flowing velocity of the high temperature fluid is imparted to the high temperature fluid by the patterns of irregularity in the zones. It is possible to distribute uniformly the high temperature fluid to the zones to cause it to flow over the entirety of the heat transferring face so as to obtain a uniform flow rate of the high temperature fluid on the zones, improve the contact efficiency of the high temperature fluid with the heat transferring face and improve the heat transfer efficiency of the high temperature fluid to the low temperature fluid through the heat transferring face, unlike the conventional case that the high temperature fluid does not flow in a uniform state on the heat transferring face due to the biased position for the supply of the high temperature fluid.
