Description

The broken dry flour production line of ardealite
Technical field
The present invention relates to ardealite processing equipment field, in particular to the broken dry flour production line of a kind of ardealite.
Background technique
Monoammonium phosphate is a kind of fire-retardant, extinguishing chemical well, be widely used in timber, paper, fabric it is fire-retardant, while also using Make dispersing agent, the agent of enamel glaze, the compounding agent of fireproof coating, dry powder fire extinguishing agent of fiber process and dye industry, medicine and print Dataller's industry etc. also has use.There is wet process to produce monoammonium phosphate and thermal method production monoammonium phosphate by manufacturing process point, with national and at different levels The strict control that department uses the energy, since its production energy consumption is lower than thermal phosphoric acid, product index is able to satisfy more phosphoric acid by wet process Aspect requirement replaces thermal phosphoric acid in some field phosphoric acid by wet processes substantially, and the market share is 90% or more.
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 by-product 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 be only 2%- currently with rate 3%.Most of associated production enterprises all select ardealite direct emission not only taking up a large amount of soils, and can generation environment dirt Dye.The main reason for causing this phenomenon first is that in the market lack profession processing ardealite equipment, if enterprise is given birth to other Producing line substitution, production efficiency is too low, and profit margin is little, and production is short of power.
For example, be method more mature in current ardealite application with ardealite production building gypsum, ardealite is net Change processing, removes phosphate, fluoride, organic matter and soluble-salt therein, complies 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. building gypsum).But Ardealite after long-term stacking would generally generate a large amount of agglomeration, these agglomeration volumes are big, and internal moisture is not easy to evaporate, when dry It can usually accumulate and result in blockage in rotary kiln, seriously affect ardealite processing efficiency.
In addition, the high-temperature material that rotary kiln generates often needs to be cooled to certain temperature, Fang Kejin in ardealite drying course Row conveying is stored and is 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 a large amount 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.
Summary of the invention
The purpose of the present invention is a kind of broken dry flour production line of ardealite is provided, in rotary kiln according to the above problem Interior setting material-blockage preventing device avoids blocking, and substitutes cooler in rotary kiln cooling zone setting water-cooling structure and cools down to material, And the structure for improving frying furnace improves the efficiency of production line processing ardealite, reduces production cost, improves the utilization rate of ardealite.
The purpose of the present invention is achieved through the following technical solutions: the broken dry flour production line of ardealite, including Rotary kiln, crusher, frying furnace and ball mill, ardealite wet basis are admitted to crusher in rotary kiln and carry out brokenly after drying and dewatering Broken, then using the calcining of frying furnace and ball mill grinding finished product land plaster, the Rotary kiln installation is in kiln head cover and kiln Between tail smoke-box, rotary kiln is followed successively by preheating zone, intermediate zone, clinkering zone and cooling zone from kiln head cover to kiln tail smoke-box, described Rotary kiln is Anti-blockage ardealite high temperature rotary kiln, and the cooling zone of rotary kiln is equipped with water-cooling structure, and the frying furnace is air blast Type phosphogypsum powder frying furnace.
