Vortex street mixer

Abstract

The invention discloses a vortex street mixer which comprises an inlet flange, a vortex street generator I, a vortex street generator II, a mixer main body pipe and an outlet flange, wherein the mixer main body pipe is of a hollow cylindrical structure, the inlet flange and the outlet flange are respectively welded at the upper end and the lower end of the mixer main body pipe, the vortex street generator I and the vortex street generator II are both set to be of a hollow isosceles triangular column structure, and the vertex angle directly faces the fluid inlet direction; the vortex street generator I and the vortex street generator II are arranged by forming a right angle by passing through the center of circle of a pipeline interface, the vortex street generator I is welded between the upper end face and the lower end face of the mixer main body pipe, and the vortex street generator II is welded on a corresponding side wall vertical to the axis of the mixer main body pipe. The pipeline mixer which is simple in structure, high in use reliability and remarkable in mixing enhancing effect is favorable for generating eddy current, improving the fluid mixing degree and improving the mixing effect, is used for liquid-liquid and gas-gas quick mixing reaction, and is wide in applicability.

Description

technical field [0001] The invention relates to the technical field of water and gas mixing, in particular to a vortex street mixer, that is, a vortex street mixer used for liquid-liquid and gas-gas rapid mixing reactions. Background technique [0002] At present, the liquid-liquid and gas-gas mixing devices of water treatment and gas mass transfer devices are widely used in the market, such as spiral mixer, Venturi mixer, static mixer and so on. The cost of the spiral mixer is high, the resistance of the blade to the fluid is large during use, and the impact of the fluid on the blade is large, and the practicability in the high-speed fluid pipeline is greatly reduced, especially the small-caliber mixer is more difficult to manufacture and is more likely to be damaged. Venturi mixer needs high-pressure fluid to participate, the structure is complex and the application conditions are relatively harsh, the fluid agitation strength is not strong enough, the mixing effect is ins...
