Venturi high-efficiency mixer and working mode thereof

Technical Field

The invention relates to the field of mixers, in particular to a high-efficiency Venturi mixer and a working mode thereof.

Background

The Venturi mixer has no moving part and consists of three parts, including nozzle, sucking chamber and diffuser pipe. The working fluid with certain pressure is sprayed out at high speed through the nozzle, so that the pressure energy is converted into velocity energy, vacuum is formed in the outlet area of the nozzle, the pumped medium is sucked out, the two strands of media are mixed and subjected to energy exchange in the pressure expanding pipe, the velocity energy is reduced into the pressure energy, and finally the pressure energy is discharged at the pressure higher than the atmospheric pressure. The venturi mixer is a device integrating air suction and mixing reaction. The unique design of the mixing air chamber is that the air flow and the air or the liquid are mixed and sprayed forcefully, so that the stirring is uniform and complete, the generated bubbles are more and fine, and the gas dissolving efficiency is improved.

The current venturi mixer has the following problems: the flow rate of the mixed fluid flowing out is constant and cannot be adjusted.
