Title: Method of cleaning inner surface of heat transfer pipe in heat exchanger
Inventor: SAKAMOTO TAKAO
IPC: B08B9/02
Filed: 1985-05-02
Abstract: PURPOSE:To make it possible to automatically carry out cleaning of a number of heat transfer tubes surely without erroneously operating the heat exchanger by discharging a gas into a liquid in a bubble state at the inlet end of a heat transfer tube to form a gas=liquid mixed flow which flows down through tubes transmitting an ultrasonic wave to the gas-liquid mixed flow in the liquid to remove matters adhering to the inside of the tube. CONSTITUTION:When scales of cooling water adhere to the inner surface of a heat transfer tube 3 with the driving, a gas is caused to flow down into the heat transfer tube 3 from a cleaning head 10 in a bubble state and transmits an ultrasonic wave in the liquid to remove scales and clean the same. For this reason, the heat exchanger is provided with a cleaning head 10 accommodated in a water inlet side water chamber 4, a support arm 11 supporting the same, an expansible shaft 12, and a driver 13 for driving the same, and a location controller 14 which moves the same from the external part to an arbitrary position of the tube group. A gas flowing down through the heat transfer pipe 3 is discharged to the water outlet side water chamber 5 and is accumulated in a gas reservoir 20 provided in the water outlet side water chamber 5. The gas is extracted by a venting pump 22 and is exhausted out of the system via a pipe 21.
