Description
Technical field
The present invention relates to powdery flocculating agent, flocculant and filter aid in slime water treatment technique it is evenly dispersed in the liquid phase and
The field of mixed dissolution, and in particular to a kind of mealy medicine is evenly dispersed in the liquid phase and mixed dissolution system.
Background technique
Overwhelming majority coal preparation plant, China all uses wet coal preparation, and slime water treatment is important in wet coal preparation process flow
Link is required to the clarification of coal slime water depth, closed water circuit from the aspect of economical and environmentally friendly.Coal preparation plant generallys use mixed
Solidifying method handles black water, and so-called Coagulation Method is exactly to add coagulant into coal slime aqueous systems, so that in coal slime aqueous systems
Grain leans on gravitational settling after reuniting.The most commonly used is organic polymer coargulators, such as polyacrylamide for coagulant, due to organic high
Molecular flocculant has molecular weight big, the features such as side chain is long, therefore the drawbacks such as that there are dissolution times is longer, dissolution is insufficient, if
Dispersion mixing is uneven in water for medicament, dissolves and is not thorough at the appointed time it will cause medicament, and medicament concentration of aqueous solution is inclined
Phenomena such as low, medicament wastes, also will have a direct impact on the treatment effect of black water when situation is serious.The traditional flocculant of coal preparation plant is matched
Method processed be by manually directly powdery flocculant be added to be mixed bucket in directly stir, but due to be fed it is uneven, mixed
Close it is insufficient often will cause medicament conglomeration, the problems such as dissolution is insufficient, and need to be arranged special post driver to observe liquid
Position and on time addition powdery flocculant, there are certain hysteresis quality and dosage has artificial deviation.Although utility model
201721157662.5 propose to be fed using screw(-type) feeder to solve the problems, such as to be fed non-uniform, patent of invention
201410260122.4 propose to reach the evenly dispersed purpose of feeding process Chinese medicine using medicament dispersing sieve, but can not solve
The problems such as undercompounding, whipping process conglomeration, thus assistant officer needs a kind of mealy medicine evenly dispersed in the liquid phase and mixed dissolution
System solves the problems, such as that medicament undercompounding, that course of dissolution " swelling " conglomeration causes mealy medicine to dissolve is insufficient.(swelling
If referring to that the several particles of the high polymer coagulant of powdered granule are got together to fall into the water again, after the expansion of some particle surface layer, packet
Other particles are wrapped up in, leading pelleting cannot separate, and cause to dissolve incomplete phenomenon.)
Summary of the invention
It is an object of the invention to overcome above-mentioned the deficiencies in the prior art, medicament high efficiency dispersion hybrid system is designed, including
