    • The invention describes a unique and novel pyrolysis kiln for separating water vapor from a carbonaceous feedstock early in the pyrolysis process. The kiln structure includes two fans, one located near the proximal end of the kiln, the other near the kiln's distal end. Both fans create a local decrease in pressure at the respective ends with a dead zone in the intermediate region between the two ends of the kiln. At the proximal end, low temperature volatiles are removed, especially water vapor, and directed to a waste water cleanup station. Early removal of the water vapor makes the remaining pyrolysis process substantially more efficient. At the distal end, the high temperature hydrocarbons and other impurities are removed in a conventional manner and directed to a hot gas cleanup unit.
    • 本发明描述了一种独特且新颖的热解窑,用于在热解过程中早期从碳质原料中分离水蒸汽。 窑结构包括两个风扇,一个位于窑近端附近,另一个靠近窑的远端。 两个风扇在窑的两端之间的中间区域处的死区产生局部相应端部的压力降低。 在近端,除去低温挥发物,特别是水蒸气,并引导到废水净化站。 早期去除水蒸气使剩余的热解过程显着更有效率。 在远端,以常规方式除去高温烃和其它杂质,并引导到热气体净化单元。

    • An electrochemical remediation apparatus comprising a cylindrical tank having a plurality of vertical anodes suspended downwardly from a dome-shaped lid and positioned around the circumference of the tank spaced radially inwardly from the inner sidewalls of the tank. A single cathode is positioned at the axis of the cylindrical tank and removably mounted to the lid. A cylindrical metal ion permeable membrane is positioned between the anodes and the cathode. A plurality of nozzles spaced circumferentially around the tank directs pressurized fluid into the tank at a direction having radial, axial and circumferential components. A mixture of water, acid and contaminated earth consisting of approximately 50% contaminated earth is poured into the region between the membrane and the tank sidewalls. The mixture is incubated and fluidized, and contact between metals in the mixture and the anodes causes the metal contaminants to act as sacrificial anodes and thereby to ionize. The metal cations are electrostatically attracted to the central cathode and deposit thereon.
    • 一种电化学修复装置,包括一个圆筒形容器,该圆柱形容器具有从圆顶形盖子向下悬挂的多个垂直阳极,并且围绕容器的圆周径向向内延伸。 单个阴极定位在圆柱形罐的轴线处并可拆卸地安装到盖子上。 圆柱形金属离子渗透膜位于阳极和阴极之间。 围绕容器周向间隔开的多个喷嘴在具有径向,轴向和周向部件的方向上将加压流体引导到罐中。 将由约50%污染的土壤组成的水,酸和污染的土壤的混合物倒入膜和罐侧壁之间的区域。 将混合物温育并流化,并且混合物中的金属与阳极之间的接触导致金属污染物作为牺牲阳极,从而电离。 金属阳离子被静电吸引到中央阴极并沉积在其上。
