    • Process and furnace plant for production of liquid metal. The furnace comprises an apparatus (1) for treatment of furnace gas. The apparatus comprises a wet scrubber, preferably a venturi scrubber (6), such as an air gap scrubber, with an outlet connected to a mist eliminator (7) comprising a non-swirling separating device (30, 36), for example a Sulzer Mellachevron™ and optionally a second non-swirling separating device comprising a knitmesh combined with a second Sulzer Mellachevron™. Optionally, the demister (7) may comprise an inlet diffuser, such as a vane-type inlet device, in particular a Shell Schoepentoeter™ (22).
    • 用于生产液态金属的工艺和熔炉设备。 该炉包括用于处理炉气的设备(1)。 该设备包括湿式洗涤器,优选文丘里洗涤器(6),例如气隙洗涤器,其出口连接至包括非旋转分离装置(30,36)的除雾器(7),例如苏尔寿 Mellachevron TM和可选的第二非旋转分离装置,其包括与第二Sulzer Mellachevron TM组合的针织网。 可选地,除雾器(7)可以包括入口扩散器,例如叶片式入口装置,特别是Shell Schoepentoeter TM(22)。

    • This invention is a premelting vessel (1) and a method for premelting charge (12) before the charge (12) is introduced into a melting vessel (50) or furnace (50) in the steelmaking and metallurgical industry. The invention uses chemical energy from fuel sources layered within the charge (12) and from available process off-gases within a plant to premelt the charge (12) before it is transferred to the melting vessel (50), thereby reducing the melting phase time and increasing the production rate. This invention also eliminates the use of a post-combustion chamber.
    • 本发明是在炼钢和冶金工业中将进料(12)引入熔炼容器(50)或炉(50)之前的预熔化容器(1)和预充料装置(12)的方法。 本发明使用来自燃料源的化学能,其分配在电荷(12)内,并且在转移到熔融容器(50)之前,将电荷(12)预先熔化,从而降低熔融相时间 并提高生产率。 本发明还消除了后燃烧室的使用。

    • The preliminary cleaning stage of a dust extraction installation for blast furnace gas consists of a large-size cyclone (10) which comprises a vertical pressurized tank (14). A blast furnace gas line (12) arriving from the blast furnace is connected to an axial delivery device (34, 26, 28, 50) situated at the upper end of the pressurized tank (14). The delivery device (34, 26, 28, 50) is configured such that it introduces the blast furnace gas into the pressurized tank (14) in an axial direction. A swirl device (58) with guide vanes (66) is positioned below the axial delivery device (34, 26, 28, 50) and causes the blast furnace gas which is axially introduced into the pressurized tank (14) to swirl about the axis (30) of said pressurized tank (14).
    • 该预清洗步骤对高炉煤气除尘安装由一个大的旋风分离器(10),它包括一垂直压力容器(14)形成。 从高炉煤气到来线(12)一种高炉被连接到在压力容器(14)的上端部连接的轴向进给装置(34,26,28,50)。 所述进给装置(34,26,28,50)被设计为使得在轴向上进入压力容器中的高炉煤气以发起(14)。 (34,26,28,50)布置甲旋流装置(58)与所述轴向进料装置下方的导向叶片(66)。 输送其轴向到压力容器(14)引入的高炉煤气中有关压力容器(14)的轴线(30)方案是旋转运动。
