Description

本発明は以上のような従来のアルカリ賦活炭の製造装置における課題を考慮してなされたものであり、第一の目的は、トンネル炉内に異常が発生した場合に、トンネル炉内の賦活反応生成物、未反応物を、安全に炉外に排出することができるアルカリ賦活炭の製造装置を提供することにあり、第二の目的は、炉壁に付着したアルカリ金属化合物を効率良く除去し、安定してアルカリ賦活炭を製造することができるアルカリ賦活炭の製造装置を提供することにある。 The present invention has been made in consideration of the problems in the conventional alkali activated carbon production apparatus as described above, and the first object is to activate the reaction in the tunnel furnace when an abnormality occurs in the tunnel furnace. The second object is to provide an apparatus for producing alkali activated carbon that can safely discharge products and unreacted materials outside the furnace. The second object is to efficiently remove alkali metal compounds adhering to the furnace wall. An object of the present invention is to provide an apparatus for producing alkali-activated charcoal that can stably produce alkali-activated charcoal .
