Title: Treating method of hot water produced from deep underground
Inventor: HARADA GENZABUROU
IPC: C02F5/02
Filed: 1978-11-30
Abstract: PURPOSE: To prevent scale from depositing on the hot water transport pipe used in a geothermal power station by a method wherein hot water from deep underground is added with calcium carbonate particulates and silicic acid particulates and produced reaction products are settled for separation.  
     CONSTITUTION: Hot water A produced from deep underground is introduced into the first reaction tank 2 into which additive B is added from the hopper 1 to allow the first reaction to occur, and the product is guided into the second reaction tank 3. In the settling tank 4, produced material is allowed to settle, which is dehydrated as slurry by the separator 5 to recover amorphous silicic acid D. Meanwhile, overflow from the settling tank 4 is guided into the return well as return water C. As the additive, it is preferable to use particulates of calcium carbonate and silicic acid either in a single form or their combination, with pH of adding water being adjusted to 5.0W9.0. The amount of additive is 1/10W20 times of the contained silicic acid. Settlement or precipitation reaction occurs at high temperatures and reaction time of about 10W30 minutes is sufficient.

Filed: 1980-10-21
Abstract: PURPOSE: To obtain a desired melt-stuck state over the entire length by forming an intermediate layer mixing with the 2nd layer at low m.p. between the 1st layer and the 2nd layer in centrifugal casting of steel type double layer pipes.  
     CONSTITUTION: At the point of the time when the 1st layer of cast metal of steel type including alloy steels at well solidifies to about 80W100% thicknesses from the outside surface after casting of said 1st layer, intermediate layer cast metal of 1.3W 4.0% C, 1.0W3.0% Si, <3.5% Mn and the balance Fe is cast. This intermediate layer metal is lower in solidification temp. than the steel type cast metal of the 1st and 2nd layers, and does not degrade the properties of the fresh 2nd layer mixed with the 2nd layer. If the inside surface of the 1st layer in this casting is unsolidified, the mixed layers are formed, and if it is right after the completion of the solidification, both layers stick thoroughly by melting when the temp. thereof is above the m.p. of the intermediate layer metal. The 2nd layer is cast right after the completion of the casting of the intermediate layer. At this time, the intermediate layer is the partly solidified or virtually solidified layer, but when the 2nd layer of the solidifying temp. higher than this is cast, both layers mix, whereby the fresh 2nd layer melt-stuck thoroughly with the 1st layer is formed.
