Multi-cartridge stainless steel self-cleaning sediment water filter

The fluid to be filtered flows through the slotted tube filter elements of the backflushing filter, passing from the inside to the outside.
 
Contamination particles then collect on the smooth inside of the filter elements.
As the level of contamination increases, the differential pressure between the contaminated and clean sides of the filter increases.
When the differential pressure reaches its preset value, backflushing starts automatically.




 
Cleaning Process 
When the difference in pressure reaches the preset value on the electronic control unit, a series of events is triggered while water continues to flow to the system units. The flushing valve opens, pressure is released from the hydraulic piston, and water flows outside. Pressure in the hydraulic motor chamber and the dirt collector is significantly lowered, and the dirt collector nozzles begin a suction process. The water flows through the hydraulic motor, which rotates the dirt collector around its axis. The pressure released from the piston and the high pressure inside the filter, cause linear movement of the dirt collector. The combination of the linear movement and rotation significantly cleans the whole internal screen surface. The flushing cycle takes 5 seconds. The flushing valve closes at the end of the cycle and the increased water pressure returns the system to its initial position. The filter is now ready for the next cycle, with clean and filtered water flowing through the "Outlet".

 


Application Fields


Power Plants : Treatment of Industrial Water for cooling generators and filtration of 
 
sealing water to increase the service life of the Turbine Shaft sliding-ring seals in 
 
Hydro-Electric Power Stations.
 
Steel Industry: Protection of nozzles and pumps during high-pressure descaling, water 
 
treatment for blast furnaces, rolling mills, cleaning, quenching applications.
 
Chemical Industry : Improvement of product quality by filtering process media. Filtration 
 
of White water, Black Liquor, Starch, Fuel oils, Caustic Solutions, Cooking oils, 
 
brackish/salt intake water etc. For filtration of water used for cooling, process, fire 
 
protection applications.
 
Pulp & Paper Industry : Removal of fibers from white water filtrate, Protection of spray 
 
nozzles for screens of paper making machines. This reduces frequent failures caused due to 
 
clogging and wear.
 
Mining: By filtering underground, spray water of even quality is assured. This results in 
 
more reliable operation of pumps and disc cutting machines
 
Environmental Technology. Used as pre-filters before waste water treatment plants, UV 
 
Treatment, Reverse Osmosis, membrane filtration etc.
 
Sewage Treatment Plants : During Production of industrial water, filtration of a take off 
 
of the clear run can be used to save valuable drinking or well water.
 
Heat Transfer / Heat Supply : Protects heat Exchangers from clogging & wear




Chracteristics of SS multi-cartridge automatic backwash filter
 

automatic backwashing self-cleaning filter suitable for demanding environments, for different application requirements ,3500micron -50micron filter screens are available.with 8"-36" inlet/outlet diameter. The self-cleaning filtration is started by a differential pressure switch which is monitoring the pressure difference on the filter inlet and outlet.
Continuity water supply: very less cleaning water requirement ,just 1% of the out water.the flushing time is2-15 seconds, and the whole system is continuity water supply.
High filtration precision: the filtration precision can be up to 20 microns, with a variety of precision filter screens.
Large filtration area: the standard effective filtration area is larger 7 to 40 times than the entrance area.
Reliable cleaning: there are a variety of control modes, such as manual, pressure difference , time, setting and PLC program logic control .
Low-cost and simple installation: various structure forms, suitable for installation various of conditions.
Long service life: more than 10 years ; the filter screen is made of stainless steel, and if necessary, the filter screens of different specifications can easily be replaced.

Important parts for filtration system:
01. Carbon steel cycloner,
02. Stainless screen,
03. Butterfly valve
04. Sewage device, etc.
