摘要： PROBLEM TO BE SOLVED: To remove metal and nonmetal materials stuck on the surface of a material to be treated extremely well without using a special cleaning agent, combustion flame or the like. SOLUTION: In this method, after a material to be treated 1 is fed into a closed space 2 and the closed space 2 is evacuated, a non-oxidizing gas is fed and also primary heating is performed. Then, after the closed space is evacuated, secondary heating is further performed to evaporate liquid and solid materials stuck on the material to be treated 1 and the evaporated materials are housed in a condenser to condense them. Then, the non-oxidizing gas is fed again to cool the material to be treated 1. The oxidizing gas warmed by this cooling treatment is introduced into a preheating furnace 31 to preheat the untreated material to be treated 1.

摘要： PURPOSE: To recover a high purity copper with a simple treatment by incorporating copper-containing waste material into a two-step jig, raising the temp. step by step, recovering vaporized component, successively, recovering molten copper and removing the stuck component. CONSTITUTION: The copper-containing waste material is carried into a space part 3 of the two-step jig 2. The space part 3 is closed and evacuated, and organic material in the waste material is vaporized by preheating with a heating means 4 and collected with a condenser 6 and a gas absorber 7 and discharged. The temp. of the space part 3 is further raised to vaporize and recover Zn, and the heating is succeeded to vaporize and recover Pb, etc. Further, the temp. is raised to about 1200 deg.C to recover the copper as dripped molten material. After making granular material by cooling this copper drip, the granule is pulverized to detach carbon, etc., stuck to the copper surface. Successively, the carbon penetrated on the copper grain surface is removed by sending to a grinding process to improve the purity of the copper grain.

摘要： PURPOSE: To highly efficiently treat a metal-contg. waste at a low cost by crushing waste appliances, etc., heating the separated metal-contg. grain in stages in a vacuum heating furnace and recovering the vapor of the metal and nonmetal and molten material generated in each stage. CONSTITUTION: When waste is treated, the waste is crushed to 1-50 mesh, and the metal-contg. grain is recovered and separated. The granular waste 1 is then placed in a jig, introduced into a vacuum heat-treating device, passed successively through vacuum heating and vaporizing chambers 3 to 5 from a preheating chamber 2 and discharged through a cooling chamber 6. The waste 1 is preheated to 50-100 deg.C, for example, to remove water, oil, etc., heated to 250 deg.C in the chamber 3, heated to 660-750 deg.C in the chamber 4 and further heated to 750 deg.C to the temp. higher than the b.p. of the materials other than the iron to be recovered in the final chamber at 5×10 to 1×10 Torr. The separated vapor and gas are sucked into condensers 10 to 12 and gas adsorbers 17 to 19 and recovered.

摘要： PURPOSE:To constitute the security room so that a sufficient heat insulation effect is displayed by always holding the wall surface at a low temperature, and also, when a fire is generated, water is allowed to flow into hollow wall, door and window, and moreover, the fire can be extinguished by deaerating the inside of the room, and thereby display works, etc., can be protected surely from a fire. CONSTITUTION:In an entrance and an opening part such as a window, etc., a fire-proof vacuum door 2 and a fireproof vacuum window door 4 for closing them in an airtight state are installed, respectively, and also, a evacuating device 15 for setting the inside of a room 1 to a vacuum state is installed, and the fireproof vacuum door 2, the fireproof vacuum window door 4 and the wall surface 5 are formed so as to be hollow and allowed to communicate with each other, so that water can flow therethrough. It is desirable that a means for supplying nitrogen gas is provided together in the room 1.
