"V" TYPE DEBRIS SEPARATOR & SELF CLEANING STRAINERS

The Debris Filter installed in the C. W. Inlet Line is an important secondary filtering equipment. The design and the internal construction of the Debris Filter is based on the Water flow, type, size and quantity of the Debris and the Cooling Water inlet Pressure. The Debris is collected at the inner surface of the screen, housed inside the filter.

The level of debris fouling on the filter screen is indicated by monitoring the Differential Pressure across the Screen. When it reaches a preset limit, the control system initiates the debris removal operation, till the screen is cleared off the debris.

Debris accumulated on the inside surface of the screen is sucked by the debris extraction assembly which routes the extracted debris into the Debris Discharge Pipe connected to the main condenser outlet pipe or drain.

The rotation of the Flushing Assembly is facilitated by an Electric Gear drive mounted outside the Filter housing. The cleaning operation ceases once the screen is clean. The salient feature of the BGR filter is that at no time is there any significant reduction of water flow during the screen cleaning operation.

Many a times the extraction technique alone is inadequate to dislodge all the Debris from the screen. To effectively solve this problem the BGR Filter incorporates a special patented Rotating High Pressure Water Injecting Arm on the rear side of the screen.
