In this golden autumn season of October, the newly-added P.S. dedusting unit for coke plant #4 of general coking plant of Ansteel have been smoothly put into production.  This newly-added P.S. dedusting unit for coke plant #4 is the first unit contracted by ACRE, which can meet the Chinese ultra-low emission standard (particle concentration no more than 10mg/Nm3).  This project is not only a solution to P.S.dedusting for 6m coke oven required by national environment protection department, but also used as standby for maintenance of charging and pushing dedusting devices, which is helpful to the owner in controlling environment pollution and solving the problems in case of emergency maintenance.
