摘要： PURPOSE:To rapidly and inexpensively dry a particulate material by holding the material contg. moisture such as converter sludge in an atmosphere of high oxygen content to oxidize the material and utilizing the heat of oxidation. CONSTITUTION:A particulate iron-contg. material contg. moisture such as converter sludge is extruded by a conveyor 3 into an oxidation tower 2 from a mesh part 5 at its outlet, dropped on a fluidized bed 1 and pulverized to form a gas-permeable deposited layer. Meanwhile, an oxygen-enriched gas 6 is passed through a heat exchanger 7, heat-exchanged with a high-temp. exhaust gas from the oxidation chamber 2, passed through the tiny holes of the fluidized bed 1 of the chamber 2 by a blower 8 and allowed to ascend through the deposited material. The iron in the sludge is oxidized by the oxygen-enriched gas, the water contained is removed by the oxidation heat, and the sludge is dried and effectively utilized as the iron making material. The high-temp. exhaust gas from the chamber 2 is freed of fine-powder iron oxide, etc., by a dust collecting filter 9, sent to the heat exchanger 7 through an exhaust pipe 10 and utilized to heat the oxygen-enriched gas.

摘要： PURPOSE:To feed gas to each gas holder in sequence and generate with a reduced protective space by changing the gas pressure for each gas holder. CONSTITUTION:The weight of a heavy bob 23 stuck to a piston 22 is made somewhat larger than that of a heavy bob 13 stuck to a piston 12, and the gas pressure in the first gas holder H1 is made about 500mm.Aq and the gas pressure in the second gas holder H2 is made about 550mm.Aq, for example. The first gas holder H1 is initially set to retain a protective space A at its bottom, but the second gas holder H2 is set at a state not retaining a protective space at its bottom. When valves 3a, 3b are opened and gas is fed through a feed pipe 4 connected to a communicating pipe 3, the gas first flows into the first gas holder H1 with a smaller piston pressure load, the piston 12 floats up to get into contact with a stopper 15u, but the gas continues to flow in, and when its pressure reaches 550mm.Aq, it flows into the second gas holder H2 automatically, and the gas feed is stopped when the piston 22 is lifted to a position retaining a protective space B above the piston 22.
摘要翻译：目的：通过改变每个气体保持器的气体压力，按顺序将气体送入每个气体保持器，并通过减小保护空间产生。构成：固定在活塞22上的沉重锤23的重量略大于粘在活塞12上的重锤13的重量，第一气体夹持器H1中的气体压力约为500mm.Aq和气体第二气体保持器H2中的压力为约550mm.Aq。第一气体保持器H1初始设定为在其底部保持保护空间A，但是将第二气体保持器H2设定在其底部不保持保护空间的状态。当阀3a，3b打开并且气体通过与连通管3连接的进料管4供给时，气体首先以较小的活塞压力负载流入第一气体保持器H1，活塞12浮起以与止动器15u，但是气体继续流入，并且当其压力达到550mm时，自动地流入第二气体保持器H2，并且当活塞22被提升到保持保护空间的位置时，气体供给停止 B在活塞22上方。
