Description

Alkali slag mountain protector

Technical Field

The utility model belongs to the technical field of environmental protection, concretely relates to alkali dreg mountain protector.

Background

The caustic sludge is industrial waste residue, is a main waste discharged in the process of producing soda ash by an ammonia-soda process, has serious pollution to the environment, and a large amount of caustic sludge storage yards (caustic sludge hills) occupy valuable land resources and seriously affect the environmental quality of surrounding areas. As China is the largest soda production country in the world, 310-360 million tons of newly added caustic sludge are added every year. The caustic sludge contains a large amount of chloride (about 16%), and thus is difficult to handle. At present, the recycling and utilizing ways are mainly as follows: the method for treating the caustic sludge in the alkali factory is mainly used for stacking in the open air, the height of the caustic sludge can reach more than ten meters and even dozens of meters, a serious dust raising phenomenon can be generated once the surface is air-dried, and the raised dust on the surface can be treated by adopting a foreign soil covering mode and the like; the interior of the water purifier can be deliquesced by precipitation and the like to form calcium chloride or other alkaline liquid which can permeate underground, and if the liquid is not guided, the liquid can slowly permeate underground, so that underground water sources are seriously polluted. Meanwhile, the liquid in the alkali slag mountain is lost to cause a cavity, which may cause large-area collapse of the alkali slag mountain, so that the alkali slag and the alkali liquor are rapidly diffused to damage the surrounding environment, and therefore, the alkali slag mountain needs to be correspondingly protected.
