Title:
DUAL-FLUID COLLIDING JET-TYPE MICRO-NANO-BUBBLE GENERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/038310
Kind Code:
A1
Abstract:
Disclosed is a dual-fluid colliding jet-type micro-nano-bubble generation device, comprising Venturi tubes, wherein two Venturi tubes are provided. The device has the beneficial effects that the device uses a dual-fluid colliding-type structural design; collision occurs between two fluids containing micro-nano-bubbles, and thus a turbulence intensity being 1.5-3 times higher than that of traditional single-tube jets is formed to promote micro-nano secondary crushing, such that there are more micro-nano-bubbles generated, and the grain size becomes uniform; by means of collision between two foam fluids, a diffusion mode of the micro-nano-bubbles changes to a 360-degree annular disk form, thereby facilitating diffusion of the micro-nano-bubbles; a counter-acting force of a water body on the device is small due to a special collision-type structural design; therefore, when the device works underwater, other fixing devices are not needed, thereby greatly improving convenience; and compared with a traditional single-tube Venturi tube device, the present invention requires lower energy consumption in the case of requiring the generation of the same number of micro-nano-bubbles of the same grain size.
