Embodiment Construction

[0025] Preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although preferred embodiments of the invention are shown in the drawings, it should be understood that the invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0026] The present disclosure proposes a static mixer. The static mixer includes a shell and a hollow mixing unit arranged in the shell. exist figure 1 In the exemplary embodiment shown, the housing is a circular duct, but the housing may be of other suitable shapes. One end of the hollow mixing unit communicates with the outside through an inlet through which the dispersed phase enters the hollow mixing unit. The hollow mixing unit includes a left-helical ...

Abstract

A static mixer comprises a housing and a hollow mixing unit; the hollow mixing unit is arranged in the housing, one end of the hollow mixing unit communicates with the outside through an inlet, and the hollow mixing unit comprises a left screw mixing unit and a right screw mixing unit which are alternately arranged and mutually connected; the left screw mixing unit and the right screw mixing unit are each of a hollow structure, and the surfaces are provided with micropores; a mixing channel is formed between the hollow mixing unit and the housing. The static mixer has the advantages that the mixing units are each of the hollow structure, and the surfaces are provided with the micropores, so a dispersed phase can be divided into bubbles, droplets or jets and then is mixed with a dispersion phase, and the mixing efficiency is greatly improved.

Description

technical field [0001] The invention relates to material flow mixing equipment, in particular to a static mixer. Background technique [0002] For many years, industrial and scientific research departments usually use mechanical agitation to mix or react liquids. For example, the blending of lubricating oil and the reaction of chemical products, mixing tanks or reaction kettles with agitators are commonly used, and large-diameter tower equipment is used in the reaction process of gas and liquid two-phase flows, such as absorption towers, reaction tanks, etc. tower etc. The common disadvantages of the above equipment are low efficiency, high energy consumption, complex structure and large investment. Operating the shaft seal of the moving equipment under high temperature or high pressure is prone to leakage, and the maintenance cost of the equipment is high. Mechanical agitators also need devices such as motors, reducers, drive shafts, and bearing seals. The price of the ...
