a static mixer

Abstract

The invention discloses a static mixer which belongs to the field of fluid mixing devices and aims at solving the problems of existence of a dead angle in the mixing process, inconvenience in subsequent cleaning, large resistance, high energy consumption and the like in an existing static mixer. The static mixer comprises a mixer main body, wherein the mixer main body is a circular pipe, a plurality of mixer units are arranged in the circular pipe in sequence along the liquid intaking direction, and each mixer unit comprises a funnel-shaped flowing channel and a honeycomb-shaped flowing unit. A fluid enters the static mixer from an external pipeline, and the fluid disturbance is increased through the mixing of the funnel-shaped flowing channels of the mixer units and the dispersion of the honeycomb-shaped flowing units of the mixer units, so that a plurality of kinds of fluids are radially mixed. The static mixer has the advantages of simple structure, uniformity in fluid mixing, small fluid mixing resistance and low energy consumption.

Description

technical field [0001] The invention relates to a fluid mixing device, in particular to a static mixer. Background technique [0002] Static mixer is a kind of high-efficiency mixing equipment that has no moving parts and relies on the special structure and fluid movement of the mixing unit to disperse and mix immiscible fluids or fluids with uneven concentration distribution. At present, the common static mixers in China are SV type, SK type, SH type, SL type and SX type. These common static mixers have problems such as uneven mixing in the radial direction, large resistance, affecting the expansion of processing capacity, and mixing blind spots. Therefore, the existing technology needs to be improved and perfected to design a new type of static mixer with more industrial application value. [0003] Chinese patent CN201010587543.X discloses a static mixer comprising a channel extending along the main direction (X) with at least one mixing element arranged therein, wherein...

Problems solved by technology

This patent uses mixing elements to realize the division, turning, and merging of fluids to achieve the purpose of mixing. The resistance is too large and the energy consumption is high; Chinese patent CN201220054938. The element includes an inner tube and a partition, and the inner layer and the outer layer of the inner tube are communicated through several small holes on the inner tube and the partition

The pore size of this patent is adjustable, which can adapt to the mixing of fluids with different viscosities, but the energy consumption of the fluid is high, and there are many dead ends in the mixing process, which is easy to cause blockage of the pipeline and needs to be cleaned, which brings inconvenience to the subsequent process
