Full automatic self cleaning filter housing system
Full automatic back washing filter housing BCM series
BCM full automatic back washing filter housing is suitable for
filtering high flow, high speed, low viscosity fluid particle
impurity.
BCM full automatic back washing filter housing is a mechanical and
electrical products, with advantages of reasonable design, high
filtration efficiency, low operating costs, continuous filtration
in back washing process, etc., which is widely used in metallurgy,
chemical, electric power, oilfield injection water, ballast water,
environment-friendly water treatment, etc..
Working principle of BCM full automatic back washing filter
housing:
The filtered liquid is flowing from the inlet to the filter
housing, then going through the fixing plate into the filter
housing, the liquid flows from the filter element inside to the
outside, and then flows out from the filter vessel outlet;
Impurities produced from back washing filter flows out from the
sewage outfall.
How it works?
When liquid flows through the filter element, the solid particles
will be trapped in the inner side of the filter element. With the
increase of pollutants, the differential pressure between the
contaminated side and the clean side of the filter is gradually
increasing. When the differential pressure reaches the set value,
the differential pressure meter sends a message and the filter
housing starts automatic back washing process.
back washing process:
1.Gear motor drives washing arm to turn round by the jackshaft, the
rotation angle of the washing arm is controlled by a photoelectric
positioning switch, which will make it align to the cleaned filter.
2.The drain valve is opened, so that differential pressure will
form between the filter element of the outside (clean side) and
pollutant drainage.
3.Under the action of pressure difference, liquid flow of the clean
side will flows from cleaned filter outside to inside to carry out
back washing process, pollutants accumulated in the inner side of
the filter screen will be washed away and flow out the filter
through the sewage outfall.
4.The back washing time of each filter elment has been set, so when
the back washing time is reached, the pollution discharge valve
will be close, and this back washing process of filter element is
over, then gear motor will drive washing arm to turn again,
conducting back washing to the next set of filters, sewage valve
will be open again., and so on to conduct back washing process to
each mesh.
5.After all filter cleaning is completed, the washing arm returns
to the original position under the control of the photoelectric
switch, which means a back washing cycle is end.
6.Because the back washing is washing a set of filters in turn,
therefore during the process the filter can maintain a continuous
fluid filtration state.
Set back washing process:
1.Differential pressure setting: the filter has differential
pressure gauge, which is used to set filter differential pressure.
2.Time setting: the control box has time setting device, which can
be used to set back washing process cycle according to user
requirements. Differential pressure setting and time setting are
automatic back washing configuration process, the two settings
exist at the same time, while pressure setting is prior.
3.Manual start: In addition to differential pressure setting and
time setting automatic back washing process, there is also TEST key
to manually start the process, which is used for debugging and
maintenance.
Design features of BCM full automatic back washing filter housing:
1.The internal mechanical structure of filtration equipment using
patented technology, realizes the back washing function in true
sense, which can completely remove the filter impurities, clean
every corner without dead angle, flux without attenuation, and
guarantee the filtration efficiency and long service life.
2.Filter equipment selects 304, 316L, 2205, MONEL materials wedge
filter element, with advantages of large intensity, high precision,
corrosion resistance, and the maximum filtering accuracy is up to
25 microns.
3.Through its own retrieval and strain function, filtering
equipment could realize automatic back washing, and can deal with
unstable water quality fluctuation without manual intervention.
4.Filter equipment control system is sensitive, accurate operation,
and can flexibly adjust the differential pressure and time setting
value of back washing based on different water and filter accuracy.
5.During the back washing process, each filter vessel is conducted
back washing in turn; which ensures the filter screen safety,
efficient cleaning, while other filters are not affected and
continue to be filtered.
6.Filtering equipment have less vulnerable parts, no consumable
material, with low operating and maintenance costs and easy
operation and management.
7.The filter equipment is designed compact and reasonable, with a
small size, which is flexible and convenient for installation and
movement.
8.Filtration equipment uses pneumatic drain valve, with a short
time of back washing process, less water consumption, environmental
protection and economic.
9.Filtering equipment working state is displayed by the touch
screen, and the differential pressure and time setting is
convenient for view.
Application area:
Sea water desalination, circulating cooling water and oilfield
reinjection water, ballast water for ship, boiler reuse water,
