Preparation method for high concentration dredging silt rapid dehydrating agent solution

Abstract

The present invention discloses a preparation method for a high concentration dredging silt rapid dehydrating agent solution. The method comprises the following steps: adding sodium carbonate and sodium chloride compound particles to a powdery anionic polymer dehydrating agent, sufficiently mixing the dehydrating agent, sodium carbonate and sodium chloride compound particles by stirring; and dissolving the dehydrating agent mixed solution by high-speed dispersing emulsifying equipment with the dissolution time of less than 2 min. The dehydrating agent solution is prepared after dissolving. According to the present invention, a certain proportion of water-soluble sodium carbonate and sodium chloride compounds are added to the polymer dehydrating agent for modification, each particle is fast and fully contact with water base on the combination of influent water flow mist flow condition to achieve instantaneous uniform dispersion in water, and ultimately high concentration wet-caking problem of the polymer dehydrating agent material is solved.

Description

technical field [0001] The invention relates to the field of quick treatment of dredged sea mud, in particular to a method for configuring a high-concentration dredged mud quick dehydrating agent solution. Background technique [0002] my country's land resources are seriously scarce, especially in the developed coastal areas, which is even more obvious. Reclaiming land from the sea has undoubtedly become an important way for coastal areas to obtain land resources, and it is a development measure adopted by coastal areas to alleviate land shortage. In China, dredged sea mud is generally used directly as filling material. The sea mud with high moisture content is naturally dehydrated and dried to reduce the water content of the sea mud and improve the workable strength. The time required is as long as 1-3 years, and the economic benefits are slow. [0003] In developed countries, there are many successful sea reclamation projects that directly add fast dehydrating agent to t...

AI Technical Summary

Problems solved by technology

[0005] 1) When the concentration of the agent reaches 3‰, it is easy to agglomerate, resulting in waste of the agent, a large amount of addition, and unstable concentration of the preparation, which in turn affects the treatment effect;

[0006] 2) The mixing method is used for preparation and dissolution. It takes more than 3 hours for the polymer to completely dissolve, which takes a long time;

[0007] 3) The chemical dissolving equipment occupies a large area and has a large operating cost
