Title:
DEVICE FOR PRODUCING GAS DISSOLVED LIQUID
Document Type and Number:
Japanese Patent JP2554609
Kind Code:
B2
Abstract:
PURPOSE: To effectively produce a gas dissolved liquid in real time and in large quantities with simple and small-sized equipment by causing gas to flow in liquid a little downstream of a squeezing part of a liquid passage of a mixer and jetting a gas-liquid mixed flow from a nozzle part of an outlet.
CONSTITUTION: A mixer is provided with a venturi tube 42 where a throat part 40 forming a contracted part is located in its central part. In a flared part 44 on the downstream side of the venturi tube 42 is formed into a gas inflow port 46 for mixing a gas fed from a gas tank into a passage, a little downstream of the throat part 40. The end of a line is connected to the gas inflow port 46. On the downstream side of the widening part 44 is formed into a mixing part 48 for mixing the gas flowing in from a gas inflow port 46 with a liquid in the passage. In such a way, the gas is caused to flow in a stream from the gas inflow port in a little downstream side of the squeezing part and the gas flowing in is pressurized and dissolved in liquid in the mixing part where the flow slows down and static pressure is increased, and further, the mixed bubbles are sheared and subdivided.
