Description
Technical field
The present invention relates to ardealite process equipment field, more particularly to a kind of ardealite is broken to dry flour production line.
Background technology
MAP be it is a kind of well fire-retardant, extinguishing chemical, be widely used in timber, paper, fabric it is fire-retardant, while also using
Make dispersant, the agent of enamel glaze, the compounding ingredient of fireproof coating, the powder extinguishing agent of fiber process and dye industry, medicine and print
Dataller's industry etc. is also used.There is wet method to produce MAP and Re Fa production MAPs by manufacturing process point, with national and at different levels
The strict control that department is used the energy, phosphoric acid by wet process is less than thermal phosphoric acid due to its energy consumption, and product index can meet many
Aspect requirement, replaces thermal phosphoric acid, its market share is more than 90% substantially in some field phosphoric acid by wet processes.
Main By product is ardealite, our times phosphoric acid by wet process gross annual output amount about 2.6 hundred million during Wet-process Phosphoric Acid Production
Ton (in terms of P2O5), about 1.5 hundred million tons of accessory substance ardealite, utilization rate only 4.3%-4.6%.It is expected that China arrives the year two thousand twenty phosphate fertilizer
(P2O5) demand will be up to 1.3 hundred million tons, and ardealite annual emissions will be more than 20,000,000 tons at that time, and are only 2%- currently with rate
3%.Most of associated production enterprises are all selected directly to discharge ardealite, and a large amount of soils are not only taken up, and can generation environment dirt
Dye.The one of the main reasons for causing this phenomenon is the equipment that in the market lacks specialty processing ardealite, if enterprise is given birth to other
Producing line is substituted, and production efficiency is too low, and less, production is short of power profit margin.
For example, it is method more ripe during current ardealite is applied that plaster of Paris is produced with ardealite, ardealite is net
Change is handled, and is removed phosphate therein, fluoride, organic matter and soluble-salt, is complied with the requirement of construction material.After purification
Ardealite slough free water and the crystallization water through drying, calcining, then aged can be made into semi-hydrated gypsum (i.e. plaster of Paris).But
Ardealite after long-term stacking would generally produce substantial amounts of caking, and these caking volumes are big, and internal moisture is difficult evaporation, when drying
It can usually accumulate and result in blockage in rotary kiln, have a strong impact on ardealite processing efficiency.
In addition, in ardealite drying course, the high-temperature material that rotary kiln is produced often needs to be cooled to certain temperature, Fang Kejin
Row conveys, stores and be further processed.Conventional way is to install cooler additional in the end of rotary kiln at present, passes through cooling
Machine takes away the heat on material.But substantial amounts of electric energy can be consumed in the cooler course of work, equipment operating cost is higher, and
The long-term operational failure rate of machine can constantly rise, and production line can not continuous and steady operation.
The content of the invention
The purpose of the present invention is there is provided a kind of broken dry flour production line of ardealite, in rotary kiln according to above mentioned problem
