Metal Automatic Tubular Filter MF Seires for Pulp and Paper
Industry
Description
Tubular Filter is the automatic filtration system according to the
modular design concept. It has the high reliability and flexibility
for expanding.we can increase or decrease the filter units to
complish the whole system per the low or high flow rate and low or
high impurity content. It has the following features: running
automatically, very durable, no manual cleaning, very easy to open
for maintenance, with unique V-SLOT filter element, completely
back-flushed and less back-flushing discharging liquid. This kind
of filter can purify the liquid and protect the downstream key
equipments. It is designed and manufactured by the high
performance, high quality, high reliability standard and has the
world class quality.
Working Principle
This kind of filter has two model for your selection since using
two backwash water source,one is internal backwash,remove the
filter cake by filtered clean water reverse flowing; another is
outer backwash,remove the filter cake by clean water or clean air
from external access.Although each modular filter is fabricated to meet specific
application requirements,all share common features.
Each unit are mounted on a common header to provide continuous flow
during backwash,the individual modular self clean filters use
permanent ,reusable filter elements along with the quarter turn
caps,o-ring seals and element centering pins as found about In-line
filters.
A wide range of options may be specified,including different seal
materials,manual backwash,or automatic backflush(by time clock or
pressure differential)that can be linked to PLC

Applications:
■ Applicable Industries: raw water treatment, water treatment
system, cooling system, power generation, steel mill, pulp and
paper, mining, petrol-chemical, municipal facility, etc.
■ Applicable liquid types: raw water, process water, clean white
water, super clean water, circulating cooling water, high pressure
spraying water, low pressure spraying water, sealing water, squirt
cut water, etc.. Various raw oils like diesel, gasoline, naphtha,
residual oil; hot rolling coolant or cold rolling coolant in the
steel mill
Technical Features and Advantages
■ Only one extra filter module as the spare for the whole system,
low breakdown risk, less investment cost
■ The filter modules can be switched off-line and manual cleaned
one by one with no filtering interruption.
■ It only takes 5 seconds to open the filter module's lid. Very
easy to pull the filter element out and low operation cost.
■ When filtering some difficult impurities and periodic manual
cleaning is necessary, it is the best solution
■ Back-flush by the valve switching, no complicated mechanic
structure, very easy for maintenance.
■ Continuously filtering when back-flushing, no systen downtime and
downtime cost.
■ Modular combination, easy for expansion, increase the flowing
capacity by adding several more filter modules
■ With V-SLOT slotted filter element, easy to clean completely,
extreamly durable and long service life.
■ MFV filter applies to the filtration before the pump or with very
low inlet pressure by external fluid back-flushing
■ Modular combination with high quality ball valves, instruments
and control system of high reliability
