干法水泥厂收尘的设计与实践

在水泥厂的生产过程中会产生大量的废气，废气中夹带着一定量的粉尘，一个２０００ｔ／ｄ级的水泥厂一天要向大气中排放约２０００万ｍ３（标）以上的废气（不同配置的水泥厂会有一些差异），即使水泥厂是达标排放，按１００ｍｇ／ｍ３（标）的排放浓度计，一天要向大气中排放２０００ｋｇ的粉尘，如果按５０ｍｇ／ｍ３（标）的排放浓度计，一天也要向大气中排放１０００ｋｇ的粉尘，也就是说一年要向大气中排放３１０ｔ以上的粉尘。 从水泥生产的特点看，水泥厂是个产尘的企业。在水泥的生产过程中，进厂的大块原料首先要被破碎成小颗粒状…

Design and Practice of Dry Cement Plant Dus Collection

Cement plant are dust porducing enterprises. Dust loading from process has the feature of enviornment enclosure and large ehaust gas emission. At present, two dedusting methods by precipitation and filtration bag filfer and E.P.are generally used in cement plants. From the view of environmental and water source savings, bag filters will be more and more used in future. For dust emission from materials crushing and handling the optimal method is to make combination of initiative and possitive amnagement and treatment.
