Working principle: a kind of ceramic membrane cross-flow filtration device, including intake pump 3, circulating pump 4, backwashing pump 20, ceramic membrane group
Part 5, in-site chemical cleaning device and back washing device.Material liquid enters system by water inlet ON/OFF electrically operated valve 2, is then sent
It to intake pump 3, is used for system boost, then by circulating pump 4 by raw water to ceramic film component 5, raw water passes through membrane component,
Under pressure effect, raw water is divided into two kinds of forms, and producing water was that drainage is oozed out by membranous wall, and concentrated water is flowed through along membrane component, from film
The element other end comes out.Membrane component water inlet, produce water water and concentrated water end install respectively pressure and flowmeter for measure pressure and
Flow.
The concentrated water a part come out from the membrane component other end recycles in circulation loop, and a part is through 31 row of concentrated water outlet end
Out, positioned at the concentrated water three-way valve 9 of concentrated water outlet concentrated water can be sent back to material liquid input end 1 or by concentrated water outlet by its
Transmitting system, three electrically operated valves of concentrated water outlet, when one of concentrated water ON/OFF electrically operated valve 8 is for reducing backwash
The pressure of concentrated water outlet, and another two adjusts motor-driven valve, concentrated water coarse adjustment electrically operated valve 6 and concentrated water accurate adjustment electrically operated valve 7, because
