Liquid jet mixer and design method thereof

Abstract

The invention discloses a liquid jet mixer which comprises a dispersion jet head, a steady flow section, a jet mixing section, a plurality of dosing pipelines and a slurry pipeline, and the dispersion jet head, the steady flow section and the jet mixing section are sequentially connected and arranged from left to right; and the dosing pipeline comprises a short pipe, a dosing valve, a dosing pipe joint, a dosing filter and a dosing hose joint which are sequentially connected from bottom to top, and the slurry pipeline comprises a bent pipe, a valve, a pipe joint, a filter and a hose joint which are sequentially connected from bottom to top. By utilizing the principle of high-speed jet mixing and dispersion re-mixing, the mixing uniformity is high, a four-stage homogenizing function is realized, the retention rate of paper pulp fibers is improved, a medicament and the paper pulp fibers are not easy to hang on the wall, and the quality of paper products is ensured; the structure is simple, reliability is high and maintenance is not needed; matched power is not needed, extra energy consumption is avoided, the medicine consumption is small, the sewage treatment capacity is reduced, and therefore the operation and maintenance cost is low, and the economic benefit is high.

Description

technical field [0001] The invention relates to the field of liquid mixing and homogenization, in particular to a liquid jet mixer and a design method thereof. Background technique [0002] A variety of fluid mixing processes are widely used in many fields such as papermaking and water treatment, and the mixing process has high requirements for mixing uniformity, so as not to affect the production process and final product quality. [0003] However, there are many defects in the existing technical fluid mixing technology and fluid mixing equipment. Either the mixing uniformity is not up to standard or the equipment is too complicated. If the mixing uniformity is not up to standard, it will affect the product quality, and if the equipment is too complicated, the initial cost and maintenance cost will be too high. high. For example, in the papermaking process, it is necessary to add a variety of liquid medicines to the slurry and mix them. There are two traditional methods: o...
