Technical requirements: The equipment is used for the filtration system of Lyocell fiber production line. It is a disc type layer by layer scanning automatic backwashing filter with automatic backwashing and continuous filtration capabilities. There are no dead corners in the chamber, and the flow rate changes by 1.3-2% during backwashing. After filtration, the constant pressure control ensures stable output pressure. 1、 Technical parameters 1.
