Apparatus for removing foreign matters from condenser cooling water

A foreign matter removing apparatus for condenser cooling water comprising:

• an inverted frusto-conical barrel,
• a filter mounted in said barrel and having a form substantially the same as that of said barrel and further having an upper and lower portion,
• an unfiltered cooling water inlet pipe connected to a side portion of said barrel,
• a filtered cooling water outlet pipe connected to an upper portion of said barrel,
• a foreign matter discharge pipe connected to a side portion of said barrel,
• a butterfly valve disposed in said unfiltered cooling water inlet pipe for adjusting the flow of water into said barrel to either directly flow into said barrel for filtering or to tangentially flow into an annular passage between the inner peripheral surface of said barrel and the outer peripheral surface of said filter to form a downward spiral flow which separates foreign matters from the outer peripheral surface of said filter and discharges the same from said foreign matter discharge pipe, and
• flow blocking means on an upper portion of said filter opposite said cooling water inlet.

A foreign matter removing apparatus for a condensor cooling water comprising:

• a generally cylindrical barrel,
• a filter mounted in said barrel, said filter having an upper and lower portion,
• an unfiltered cooling water inlet pipe connected to a lower side portion of said barrel,
• a filtered cooling water outlet pipe connected to an upper portion of said barrel,
• a foreign matter discharge pipe connected to an upper side portion of said barrel opposite said inlet,
• a butterfly valve disposed in said unfiltered cooling water inlet pipe for adjusting the flow of water into said barrel to either directly flow into said barrel for filtering or to tangentially flow into said barrel for filter cleaning, and
• flow blocking means opposite said discharge pipe only on an upper side portion of said filter.
