Apparatus and process for production of nanobubble liquid

Abstract

An apparatus and process for production of a liquid containing fuel that avoid the need to add any extra surfactant and also the need to apply ultrasonic wave energy and attain high stability of minute bubbles, etc. Production apparatus for a liquid containing fuel comprises pump for pressurizing a stored fuel and nanobubble generating unit adapted to inject a liquid containing the pressurized fuel. The apparatus may be equipped with homogenizing means for storing the liquid containing fuel. The process for production of a liquid containing fuel is characterized by sequentially performing storing of a liquid containing fuel in storage means, pressurizing the liquid so as to obtain a high-pressure liquid with a given pressure, injecting the same through a nozzle into a matrix of liquid containing fuel and effecting collision thereof with a wall so that nanobubbles of foreign substance are dispersed in the matrix of liquid containing fuel.
