Filed: 1978-02-14
Abstract: PURPOSE: To heighten the efficiency of energy recovery, by adding an expansion turbine and pressurizing and introducing the high-temperature exhaust gas from a hot gas furnace into the turbine.  
     CONSTITUTION: The expansion turbine 10, an air compressor 11 and an electric generator 16 are installed at the downstream of an exhaust gas line 9 of the hot gas furnace 8. When a bypass valve 13 at the upstream side of a chimney 14 is closed and a shut-off valve 18 and a governor valve 21 are opened, a part of the exhaust gas 1 of a blast furnace is introduced into a furnace top pressure revovery turbine 5 to drive an electric generator 17 and another part of the gas 1 is introduced into the hot gas furnace 8 to be burned with high-pressure air supplied from a burning air line 20. The burned gas is introduced into the exhaust gas energy recovering expansion turbine 10 through the exhaust gas line 9 to drive the electric generator 16 and the air compressor 11. Therefore, the energy of the exhaust gas from the hot gas furnace is also effectively used. As a result, the purpose is attained.

Title: Surface processing device of stone
Inventor: ISHIZAKI MASATOSHI
IPC: B28D1/00
Filed: 1993-01-06
Abstract: PURPOSE:To improve moving speed and prevent stone from cracking by forming a nozzle with an uneven pattern appearing on the surface of the stone using a flat ejection nozzle which ejects liquid in a wide flat jet stream, and distributing pressure uniformly across a specified width area without concentrating a pressurized liquid on a single point on the surface of the stone. CONSTITUTION:A flat ejection nozzle 3 is used as a nozzle for ejecting a pressurized liquid to the surface of a stone, and an ejected high pressure water is of a wide, flat shape. Consequently, the high pressure water is ejected in a width direction at a uniform pressure and spreads at a constant pressure. Thus the surface of the stone is finished evenly across a specified area to have an uneven pattern resembling the appearance of a natural stone. Further, it is possible to form an uneven pattern efficiently by operating an ejection angle variably. In addition, it is possible to prevent the stone from cracking due to the non-concentrated ejection of the high pressure water. The processing speed is also accelerated as the nozzle 3 travels linearly.

Title: Treatment of waste water
Inventor: HATA TOSHIHIKO
IPC: C02F1/72
Filed: 1982-02-03
Abstract: PURPOSE:To reduce the high concn. COD in waste water effectively by controlling the pH of the waste water, then adding a proper amt. of sodium hypochlorite and introducing ozone through said water to treat the waste water. CONSTITUTION:After the pH of waste water contg. oxyacid ions of nitrogen and chlorine, etc. is adjusted to >=7pH, sodium hypochlorite is added until the oxidation reduction potential of the waste water soln. attains the highest potential to decrease COD and the remaining chlorine in the waste water. Ozone is introduced through such waste water to minimize the remaining COD. This method decreases the COD in the waste water by oxidizing the reductive materials in the waste water effectively by the oxidative effect of both sodium hypochlorite and ozone.
