Nitric acid supply manner and that device null for acceleration study degreasing reactor

摘要

PURPOSE: To provide a method for safely charging and exchanging nitric acid in a chemical decomposition method for a high speed chemically defatting oven. ;CONSTITUTION: A nitric acid tank (3A) used for tranportation, having a pressure hole (15) for connecting to an air-charging pipe (12) for pressing out nitric acid pressed and received in the tank main body (3A1) outside the tank main (3A1), and having a nitric acid-charging pipe (14) for flowing out the pressed nitric acid is detachably connected to a nitric acid-discharging pipe (13) for charging the nitric acid to a high speed chemically defatting oven and to an air-charging pipe (12) connected to a compressed air source (6), respectively. When the nitric acid is consumed, the nitric acid tank (3A) for transportation is exchanged with a new one, and the nitric acid-discharging pipe (13) and the air-charging pipe (12) are reconnected to the new tank (3A).;COPYRIGHT: (C)1995,JPO
