Title: Method and device for submerged injection not entraining air in liquid
Inventor: SHINODA KATSUHISA
IPC: F22D11/00
Filed: 2000-02-23
Abstract: PROBLEM TO BE SOLVED: To provide a method and device for injection by which air is prevented from dissolving in a liquid at the time of injecting the liquid into a tank for preventing the quality drop or deterioration of the liquid and the corrosion of equipment by oxygen. SOLUTION: In this method for injection, injection is performed in a state where the front end of the injecting port of the device for injection is always submerged in the liquid by lowering the front end to a depth which is equal to or lower than a low water lever 4 so that air may not be entrained in the liquid. Since a pipe is filled up with the liquid and set to a connected state after injection, an intake valve is provided above a high water level (full flood level). After injection, part of the liquid is eliminated by making air to flow naturally in the pipe by opening the valve so as to form a space in the pipe to intercept pressure. Alternatively, an electrical or mechanical valve which closes when injection ends is installed to the injected tank.  The relief pipe of an injecting tank is also lowered to the low water level or lower so that the pipe may be submerged in the liquid so as to prevent the dissolution of oxygen in the liquid.
