Condenser tube cleaning apparatus

A condenser tube cleaning apparatus, comprising:

• a condenser unit having a plurality of unit tubes in an inner region thereof;
• a foreign substance removal unit that is located at an inlet side of the condenser unit and includes a wire mesh to filter out foreign substances contained in coolant supplied to the condenser unit;
• a strainer unit configured to sort the coolant passing through the condenser unit into coolant and cleaning balls;
• and
• a ball collection unit configured to collect the cleaning balls passing through the strainer unit, wherein the ball collection unit includes:
• a 3-way valve disposed on a path of a first transfer pipe, a first end of the first transfer pipe being coupled to the strainer unit, and a second end of the first transfer pipe extends to an upper portion of the foreign substance removal unit, the valve configured to switch between a first state defining a first fluid path and a second state defining a second fluid path;
• a pump unit spaced apart from the valve and disposed on the first transfer pipe so as to supply the cleaning balls passing through the valve to the foreign substance removal unit;
• a collection unit that is disposed between the valve and the pump unit and includes a cylindrical cavity to collect the cleaning balls when the valve is in the first state;
• and
• wherein the first fluid path travels from the valve to the pump through the collection unit, and the second fluid path travels from the valve to the pump bypassing the collection unit.
