Description
Technical field
The invention belongs to the technical fields of high strength gypsum production, and in particular, to a kind of free water rotating crystal method production is high-strength
The continuous producing apparatus of gypsum.
Background technique
As country is to power environment protection, especially raising of the reduction sulfur dioxide to atmosphere pollution attention degree, China's fire
Means of flue gas desulfurization of power plant transformation enters the fast growth phase.Thereby produce a large amount of desulfurized gesso of flue gas.Present China every year there are about
8000000 tons of desulfurized gesso of flue gas outputs, if desulfurizer is all installed by whole thermal power plant of China, desulfurized gypsum yield will increase severely super
Cross 40,000,000 tons.A large amount of desulfurized gypsums face the predicament stacked, filled due to that can not dissolve, and affect ecological environment and electricity
Factory's safe operation.Comprehensive utilization of resources to desulfurized gypsum is a problem in the urgent need to address.
The main component of desulfurized gypsum is calcium sulphate dihydrate（CaSO4·2H2O）, desulfurized gypsum, which is produced as building gypsum, is
One of important use of desulfurized gypsum, i.e. desulfurized gypsum are cleaned, are homogenized, after removal of impurities, and under different crystallization conditions, tool can be made
There are the β type gypsum and α type gypsum of higher-value.Wherein, there are mainly two types of the production technologies of alpha type high-strength gypsum, first is that blocky steam
Press it is steam-cured, first is that liquid phase method produce.
Steam-cured blocky steam pressure is that the certain crystal modifier solution of dihydrate gypsum raw material and gypsum weight ratio is sent into mixing apparatus
In, it is uniformly mixed and is directly loadable into the preferable accumulator of permeability, which is sent into and turns brilliant device equipment, is set to crystalline substance is turned
It is passed through saturated steam in standby, turn brilliant equipment keeps dihydrate gypsum complete under the conditions of saturated steam medium is with temperature in heat-insulation pressure keeping
At crystalline substance is turned, the mixed type crystal that there is the polymorphic based on column crystal size class to match is formed, the material for completing to turn brilliant goes out to turn
It is sent into drying equipment after brilliant equipment and dries attachment removal water, and obtains α high strength gypsum after grinding, the blocky steam-cured method of steam pressure is simple, benefit
In large-scale production, the scale that cost, apparatus adaptability are wide, process is simple, realize technique, raising production efficiency can be reduced.
But product performance index is unstable, fluctuation is larger, thus needs to carry out final products adequately mixing and mixing, to guarantee
The consistency of properties of product.
Producing alpha gypsum powder by liquid phase method is the land plaster by raw gypsum crushing grinding at fineness in certain granules distribution, so
Blend together certain density Gypsum slurry, and heat temperature raising with water in blending tank afterwards, the Gypsum slurry after being mixed through shurry pump into
Enter to turn in brilliant device, is crystallized for the first time under the action of 90-150 DEG C of temperature, pressure 0.3-0.5MPa and crystal modifier, generate α stone
Cream slurry.The α gypsum slurry of generation enters through stock pump again in another turn of brilliant device, in 110-150 DEG C of temperature, pressure 0.3-0.4MPa
With secondary crystallization is carried out under the action of crystal modifier, 100% α gypsum slurry can be generated.It separated in α gypsum slurry, be dried to obtain
100% α gypsum crystal particle.Alpha gypsum powder purity is high, the properties of product of liquid phase method production are stablized.But the α of liquid phase method production
Gypsum, since slurry needs to be dehydrated and clean, the consumption of water is bigger, and the energy consumption that product drying needs is also bigger, while water
Processing is also current more insoluble problem.
In addition, existing high strength gypsum production equipment includes material blending tank, turn brilliant device, drying equipment etc., using current
