Description

Adjustable intelligent dynamic pipeline mixer system

Technical Field

The utility model relates to the technical field of environmental protection equipment, in particular to an adjustable intelligent dynamic pipeline mixer system.

Background

The statements herein merely provide background information related to the present disclosure and may not necessarily constitute prior art.

Water is an important resource for human survival and development, and water treatment and reuse are particularly important in the present day when water resources are extremely deficient. The use of medicaments in the water treatment process for treating raw water is an indispensable key step, the medicament type and the medicament adding amount are large, and the medicament mixing effect can directly influence the treatment effect of the rear-end process. At present, in urban water purification plants, the added medicaments mainly comprise flocculating agents, coagulants and disinfectants. Natural water or industrial water contains not only silt but also fine-grained dust, humus, starch, cellulose, bacteria, algae and other microorganisms, and these impurities form colloidal particles in a sol state with water, and the colloidal particles exhibit sedimentation stability and polymerization stability due to brownian motion and electrostatic repulsive force, and cannot be removed by a gravity natural sedimentation method in general. Different kinds of flocculating agents have different coagulation capacities to colloids, the flocculation effect of water can be improved by increasing the using amount of the flocculating agents, but when the using amount of the flocculating agents exceeds a certain value, the original negatively charged colloid in the water is changed into positively charged colloid, and destabilized colloid is re-stabilized due to the fact that the like poles of the flocculating gel body repel, so that the flocculation effect is remarkably deteriorated. A quantity of flocculant is added to the water by first allowing the flocculant to diffuse rapidly and uniformly into the water. After the flocculating agent is fully dissolved, a plurality of tiny alum flocs are formed after the generated colloid is contacted with the original colloid and suspended matters in water, and the process is called mixing. The mixing process requires a vigorous turbulence of the water stream to thoroughly mix the medicament and water in a relatively rapid time, typically tens of seconds to 2 minutes. Among them, four main factors affect flocculation: 1. the type and dosage of the medicament; 2. stirring condition and reaction time; 3. influence of pH value alkalinity; 4. the influence of temperature.

The most common modes of medicament mixing are mechanical stirring, jet flow adding and pipeline mixing. The mechanical stirring needs to build a special stirring tank, and the civil engineering investment is large. The jet flow feeding effect is unstable. Pipeline mixing is static mixer in the existing market, and static mixer structure is simple but mixing effect is not ideal. And few dynamic mixers have fixed rotation speed ratio, so that reasonable stirring speed cannot be adjusted and selected at any time, and ideal mixing effect cannot be achieved.
