Description
Technical field
The invention belongs to ardealites to calcine field, in particular to a kind of before ardealite calcining, utilize calcining kiln discharge
It preheats and the preheating kiln that preheating reduces moisture is carried out to the higher ardealite of moisture content.
Background technique
Ardealite is the byproduct of phosphorous chemical industry enterprise production, due to moisture content height, containing harmful substance and acid ion, with
And main ingredient causes bulk deposition it is thus impossible to enough be applied directly in construction for dihydrate gypsum, so that causing
Environmental pollution；For this purpose, the present inventor, which has formerly invented ardealite, removes harmful substance and acid ion by calcining, it is allowed to convert
For that can be complex phase semi-hydrated gypsum mixture that construction uses, solves ardealite bulk deposition and cause asking for environmental pollution
Topic, while intensity height, the gypsum building material of water-tolerant are provided to construction again；In ardealite calcination process, phosphorus
Gypsum passes through diminishing, and preheating after calcining, forms the mixture of anhydrous gypsum and semi-hydrated gypsum；Due in phosphorous chemical industry enterprise
The ardealite moisture content of output is higher, reaches 25% or more, if all using calcining, the water of every removal 1% per ton, it is necessary to
1 kilogram of standard coal is expended, if as soon as 30 tons of the calcining furnace daily output, light are to remove 25% Free water to need to expend 0.75
The standard coal of ton, in addition dihydrate gypsum is converted to the crystallization water of semi-hydrated gypsum, it is necessary to expend more energy；Therefore, this Shen
It asks someone formerly to have invented using sunlight shed using the natural green energy resource such as sunlight and wind, in addition neutralization additive tentatively subtracts phosphorus stone
The moisture content of cream can subtract the free moisture of ardealite 10% by sunlight shed；Then preheating kiln is used, calcining kiln is utilized
Ardealite is further dehydrated by the waste heat of discharge in preheating kiln, enters the moisture content of the ardealite in calcining kiln so just very
It is low, because if the moisture content of ardealite is high, not only waste of energy, and the production efficiency of calcining kiln can be reduced, when unit
In to need to remove a large amount of water include that Free water and the crystallization water can waste many times, to reach certain production capacity, just need
Increase the length and diameter of calcining kiln, and since place limits and transport relevant regulations, the length of calcining kiln cannot infinitely increase
Add, and diameter is no more than the limitation of shipping height；Using sunlight shed and preheating kiln treated ardealite, can satisfy substantially
Calcining kiln works normally；In order to save the energy, preheating kiln be directly entered using the hot-air that is discharged out of calcining kiln it is pre-
Heating kiln, the ardealite poplar that rolls in preheating kiln spread, directly contact with hot-air, realize and improve ardealite temperature, accelerate moisture
The effect of evaporation；In practice, it has been found that since ardealite evaporates large quantity of moisture in calcining, the heat being discharged out of calcining kiln
In air equally contain a large amount of moisture, these moisture be in hot-air it is in an overheated state, when hot-air is in preheating kiln
When contacting with the lower ardealite of temperature, cooling becomes water to the overheated steam that can cool down rapidly, and include in hot-air rapidly,
Increase the moisture content of ardealite instead, therefore, the preheating kiln adopted this method is lower to the water removal efficiency of ardealite.
Summary of the invention
It uses the hot-air being discharged out of calcining kiln to be directly entered preheating kiln for existing preheating kiln and is easy to produce moisture
Condensation, the problem of reducing the water removal efficiency of preheating kiln, the present invention propose the preheating kiln before a kind of ardealite calcining, and feature exists
