Abstract

FRANKA-Stein is a semi-industrial prototype plant for the selective decomposition of up to 1 t/h of pre-broken minerals like concrete, rocks or the like. Its main components are: (i) a powerful high voltage pulse generator that delivers a 300 kV, 15 kA pulse with a 12 Hz repetition rate; (ii) a water filled reaction chamber. In this reaction chamber the materials to be treated are exposed for a well defined time interval to the HV discharges; (iii) a transport system that continuously feeds the materials to be treated into and out of the reaction chamber; and (iv) additional components for the separation of crushed materials from water, material classification and if re-required for water cleaning and reprocessing. In this contribution, a description of the main components is given and the operation experience achieved so far is summarized. Furthermore the results from the treatment of concrete lumps are outlined and discussed with respect to future industrial applications.

FRANKA-Stein:设计、操作和工业应用

FRANKA-Stein是一个半工业原型工厂，用于选择性分解高达1吨/小时的预破碎矿物，如混凝土，岩石等。其主要组成部分是:(i)一个强大的高压脉冲发生器，可提供300千伏，15 kA脉冲，重复频率为12 Hz;(ii)充满水的反应室。在这个反应室中，待处理的材料暴露在高压放电中一段明确规定的时间间隔;(iii)输送系统，连续不断地将待处理物料送入和送入反应室;(iv)用于粉碎物料与水分离、物料分类以及如果需要进行水清洗和后处理的附加组件。在这篇文章中，对主要部件进行了描述，并总结了迄今为止取得的运行经验。此外，还概述了混凝土块处理的结果，并就未来的工业应用进行了讨论。
