平炉水蒸汽法活性炭生产工艺与设备技术改造探讨

<正>平炉水蒸汽法生产活性炭系民间创作的一种设备结构简单、投资省、见效快的物理法生产活性炭。它靠木炭在平炉内自燃供热活化,产生的烟道气供炉后的余热锅炉和烘干坪利用。主要设备是由耐火砖砌成的、顶拱底平的长方形平炉和供汽的余热锅炉等,其工艺如图所示:

DISCUSSION ON TECHNOLOGICAL TRANSFORMATION OF TECHNIQUE AND FACILITIES FOR ACTIVAT ED CARBON PRODUCTION BY THE VAPOUR METHODOF OPEN HEARTH

Activated carbon production by the vapour method of open hearth is operating with experience nowadays. Some problems have been found in both facilities and production technology. The. problems are analysed and some propsals of transformation are put forwarded. Through trial production some satisfactory results have been obtained in activating time or temperatur e and quality of products and production yield, and so. on.
