Description
Technical field
The utility model relates to the technical field that quicklime slaking prepares lime slurry, and particularly a kind of lime slurry for preparing is used for the device that the sewage heavy metal contaminants is handled.
Background technology
Heavy metal contaminants is one of main pollutent in the industry such as plating, metallurgy, and lime is widely used as containing one of WWT such as heavy metal medicament commonly used, having, lower-price characteristic.The general need that add, use of lime is prepared into lime slurry (lime slurry), i.e. quicklime slaking slurrying by unslaked lime earlier.Effective constituent Ca (OH) in the lime slurry
2Content directly influence its result of use.
The quality of unslaked lime is the important factor that influences the lime slurry preparation.In some engineering project, unslaked lime difficult quality guarantee because of various reasons, the unslaked lime foreign matter content is high.The artificial lime slaking mode of tradition exists that water loss is big, effective constituent Ca (OH) in the slurries
2Content is difficult to control, manpower consumption is big, the not high deficiency of production efficiency; The then relative complex structure of existing other lime slaking devices, deficiencies such as investment is higher, device is huger, Operation and Maintenance inconvenience, and be applicable to that mainly the lime consumption is big, the occasion of fairly largeization production, be difficult to be transplanted to relative small-scale lime consumption occasion.
Summary of the invention
The purpose of the utility model is in order to solve the shortcoming that prior art exists, and a kind of little, ciculation fluidized lime slurry preparation facilities efficiently of lime content in the lime slurry, easy and simple to handle, miniaturized, simplification, manpower consumption of being convenient to control is provided.
The technical scheme that the utility model adopts is:
Ciculation fluidized lime slurry preparation facilities; Comprise lime stock tank, fluidized reaction equipment, separated slag member and water pump; It is characterized in that; Said fluidized reaction equipment is installed in the said lime stock tank through equipment support, and said separated slag member places in the said fluidized reaction equipment, and said water pump is arranged on said lime stock tank bottom.
Further; Described fluidized reaction equipment comprises fluidized reaction zone and fluidized reaction equipment riser; The bottom of said fluidized reaction equipment or bottom side are provided with fluidisation liquid liquid outlet, and the front end feed liquor pipeline of said fluidisation liquid liquid outlet is provided with the lime slurry backflow bypass of band valve.
