CHEMICALS FEEDER AND FEEDING METHOD

摘要

PROBLEM TO BE SOLVED: To positively and stably feed chemicals into liquid without using rotating equipment such as a chemical pump. SOLUTION: One end of a supply piping 9 is connected so as to diverge from a discharge side piping of a transport pump 2 provided on a circulation piping 5 of fluids such as cooling water and the supply piping 9 is connected to a chemical diluting tank 8 via an opening/closing valve 11. A chemical piping 10 is connected so as to combine with an intake side piping of the pump 2 and is connected to the chemical diluting tank 8 via an opening/closing valve 12. A chemical introducing part 14, an air bleeding valve 13, and an exhaust valve 15 are provided to the chemical diluting tank 8. The chemical introducing part 14 includes a gate valve 16 and a chemical supply tank 17. A chemical introduced into the chemical diluting tank 8 is diluted there by liquid from the supply piping 9 and supplied to the intake side of the pump 2 from a dilute piping 10.
