Abstract

The invention discloses a spiral low-shear static mixer, relates to a static mixer and in particular relates to a spiral low-shear static mixer. The invention aims to solve the problem that the conventional static mixer is high in viscosity loss and non-ideal in uniform mixing effect. The spiral low-shear static mixer comprises a tube shell and seven spiral mixing units, wherein the seven spiral mixing units are inserted into the tube shell; and the central line of each spiral mixing unit along the length direction is parallel to the central line of the tube shell along the length direction. The spiral low-shear static mixer is used for mixing polymer mother solution and water.

Description

technical field [0001] The invention relates to a static mixer, in particular to a spiral low-shear static mixer. Background technique [0002] There will inevitably be a viscosity loss in the stage of mixing and diluting the polymer mother liquor with water. According to the analysis data, the viscosity loss rate in this stage is relatively large. Mainly, under the split swirling effect of the mixing unit of the existing static mixer, the polymer mother liquor and the aqueous solution are continuously split and turned to produce self-stirring effect, and achieve preliminary mixing through convection, shearing, dispersion, and distribution. Because of this, conventional static mixtures cause degradation of the polymer macromolecules, changing molecular properties, resulting in a decrease in viscosity, with a viscosity loss of up to 8%. And if the degree of shear division is controlled, it will affect the uniformity of the polymer after mixing, making it a contradiction. Ex...
