Method and installation for eliminating the chloride harmfulness of the biphenyl radical

摘要

The invention relates to a process and an installation for eliminating the chloride of biphenyl radical harmfulness of the pcb. / p & & p & the pcb to be treated is preheated before its introduction into a combustion furnace 1, so that it reaches its point of were more easily and raises the pcb preheated through a layer of particles mineral 6 willing in the furnace, the particles being formed of a porous inorganic substance has multiple elements and, in addition, the inside of the furnace, and more particularly the layer 6, since preheated at a temperature has 1100c by a heat source different; the pcb is then separated in benzene rings and in the gaseous chlorine which is conveyed towards a treatment chamber 13 which has the function of absorbing and to neutralize the gaseous chlorine, thereby eliminating the harmfulness of the pcb.
