UNDERWATER ORGANISM REMOVING DEVICE IN SHIP BLAST TANK USING PRECIPITATION REMOVING DEVICE

摘要

PURPOSE: A chemical injecting device is installed in a sediment removing device in a ballast tank of a ship to prevent sediment in the tank. CONSTITUTION: A main tank(9) stores a chemical, and an auxiliary tank(16) applies a certain pressure to the main tank to make density of the chemical in the sea water evenly. A chemical injection pipe(10) injects chemical to sea water through a main supplying pipe(4). A position sensor indicates filled amount of the chemical in the main tank. The flow of the chemical is controlled by a checking valve(14). An air supplying valve(19) adjust supplied air amount.
