Abstract

The invention provides a high-pressure rotational flow mixing device. The main mixing chamber of the high-pressure rotational flow mixing device is formed by connecting and combining a cylindrical mixing chamber and a conical mixing chamber in series; a liquid inlet pipe is connected with the cylindrical mixing chamber; the liquid inlet pipe is internally provided with a nozzle which can resist a pressure of larger than 10MPa; a solid phase charging opening is formed above the cylindrical mixing chamber; the axis of the solid phase charging opening is perpendicular to that of the nozzle; the outlet of the conical mixing chamber is provided with a mixing baffle plate; the baffle plate consists of 2-6 blades which are distributed at the outlet and have the angle from 20 degrees to 60 degrees relative to the horizontal plane; and the outlet of the conical mixing chamber is connected with the inlet of a constant-current elbow pipe; the elbow pipe is of a diameter-changing structure, wherein the elbow pipe inlet diameter D1/the elbow pipe outlet diameter D2=1.5-1.8, and the curvature radius of the central axis of the elbow pipe R/D=3.0-3.5. The inner wall of the mixing chamber is sprayed with a wear-resistant material mixed with solid particles, so that the abrasive resistance of a chamber body can be improved, the concavity of the spraying surface can be increased, the turbulent condition in the mixing chamber can be enhanced, and the mixing efficiency can be improved.

Description

Technical field: [0001] The invention relates to a device for mixing solid phase and liquid phase or solid phase and gas phase, in particular to a device for mixing solids such as dust and particles with liquid or gas at construction sites in fields such as oil and gas fields and coal gas fields. Background technique: [0002] At present, the commonly used mixers in the industrial field mainly include pipeline mixers and static mixers. Pipeline mixers are generally composed of pipes, nozzles, vortex chambers, perforated plates or special-shaped plates, etc. The mixing methods are divided into three types: nozzle type, vortex type, perforated plate or special-shaped plate type; It is developed from plate and special-shaped plate mixers. The mixer has two kinds of fixed helical blades, left-handed and right-handed. When the fluid passes through the helical blades, the flow direction changes and turbulence occurs to achieve mixing. Pipeline mixers are too small in size and hav...
