Description
Affiliated technical field
The present invention relates to a kind of device of chemical industry granulation, be particularly useful for the granulation of high-viscosity melt bituminous, invention belongs to chemical industry granulation equipment field.
Background technology
At present, pitch granulating and forming technology is mainly contained two kinds of methods: a kind of is method of cooling, and this method is that the solid bitumen plate is refrigerated to 0～10 ℃, again with crusher at low temperatures graded crushing become 2～10mm platy shaped particle.This method needs freezing and broken means, and energy consumption height and particle are inhomogeneous.Another kind method is a thermal spraying, and this method is that molten asphalt is delivered to special spray column, with airflow nozzle the pitch liquation is dispersed into minitype particle, feeds gas from tower bottom simultaneously, makes the moulding of pitch particle cooling drying.The final product of this method gained is a powdery or less than 0.5 millimeter spherical shape solid particulate pitch.It is mainly represented with reference to annex United States Patent (USP) 5053279.
But for melt pitch prilling process, because characteristics such as the high viscosity of molten asphalt and high cohesive force, in addition in the asphalt stock intrinsic contaminants and in the melting process of unpacking, produce such as factors such as packing material fibers, all do not retrieve at present both at home and abroad relevant report as yet with the tower rotary spray explained hereafter of granulation spheroidal particle asphaltic products..
Summary of the invention
The tower rotary spray technology of traditional granulation is to adopt the molten material is injected in the prilling spry, prilling spry is cut by the thin-walled of a metal that platform circular cone solid of revolution and internals form, on this circular cone solid of revolution generatrix, have some manholes, molten materials enters in the prilling spry of rotation, because centrifugation will form one certain thickness parabolical liquid layer will be arranged, molten materials will penetrate from spray orifice under the centrifugal pressure effect, reasons such as the fused solution chance atmospheric drag that penetrates fragment into drop, drop is shrunk to the solid spherical particle in the landing process, the Chemicals of producing with above-mentioned granulation process have urea, ammonium nitrate etc.
Owing to exist the factor of many spray orifices that results in blockage in the commercial process in molten materials self or the production system, so the work of cleaned and changed prilling spry inevitably and be frequent relatively, this is for as urea, the water miscible purifying chemical product of this class of ammonium nitrate, only needs prilling spry replacing that will be standby and (even must a not pull down) shower nozzle water or the steam flushing that will change can be as before.
If yet molten materials such high viscosity non-water soluble substance that is pitch, then above-mentioned prilling spry structure just can not adapt to its need of industrial production, because first spray orifice very easily stops up, it two is replacings after spray orifice stops up and cleaning is very difficult or it is high to clean cost.
Easily stop up the prilling spry eyelet in order to overcome molten asphalt, be difficult to the quantity-produced problem, the invention provides a kind of melt pitch rotating granulation spray dish, the spray dish is arranged at 10-300 millimeter place, pulp cutlet below, be used for directly accepting the melt pitch that injects by pulp cutlet, the spray dish is discoid, metal material, its rotating shaft is concentric with main shaft, and drive by main shaft and to make folk prescription to horizontally rotating, the upper surface of spray dish is that the radial equalization of initial point has the structure groove with the disk center, and the section form of this structure groove is a rectangle, trapezoidal, semicircle or trilateral, the end points degree of depth of this structure groove and width are 2～10 millimeters.
Characteristics of the present invention also are:
The diameter of spray dish is the 150-500 millimeter, and thickness is the 3-50 millimeter.
The quantity of structure groove is 120～360.
The below of spray dish is provided with electric heater unit.
Pitch granulation liquation divider is the container that has the insulation jacket layer, its underpart annular is evenly equipped with 4-24 pulp cutlet, when the fused liquid bitumen when pulp cutlet falls to touching on the heated spray dish end face that horizontally rotates, because centrifugation pitch liquation will slide to spray dish outer rim rapidly when rotating with the spray dish, and be tangential direction disengaging spray disk body.The molten asphalt that broken away from spray dish outer rim this moment is filminess, because causes such as its movement velocity and liquation self surface tension, film is torn into the drop of certain volume rapidly, and drop shrinks the solid particulate that is cooled to spherical shape in the process that contacts landing with air.Rotation spray dish structure has following two characteristics:
One, the pitch fused solution is motion and break away from its rotator on the end face of an open heated horizontal rotary body, owing to do not have the constraint of eyelet, so also just do not have the blocked problem of eyelet.Because for the material as rock asphalt or modifying asphalt, be may the geometrical dimension of its intrinsic solid insoluble impurity to be limited hardly before with its fusion, that also can't avoid fully still more producing in the melting process of unpacking enters fusing system such as impurity such as packing material fibers.The basic difference of the granulating principle of the prilling spry of the present invention and the traditional tower rotary spray technology of granulation just is: the prilling spry fused solution of traditional tower rotary spray technology is to eject from the eyelet of prilling spry, and the granulation spray dish fused solution of the tower rotary spray technology of the present invention then is to shed out from the open end face of spray dish.
Two, because the pitch fused solution is to move on open rotator, so relative thinner of the molten materials liquid film on the spray dish end face, cooling effect when in addition spraying the disc spins motion, so temperature that the thermal capacity that only depends on fused solution self obviously can not balancing processing requires, in addition, during initial feed the hard pitch fused solution as touch be normal temperature spray dish the time then owing to the coacervation immediately of the huge temperature difference reduces its flowability, moreover equipment still needs enough temperature after stopping and allows the defective material in the system all flow to end through the spray dish.In order to guarantee that liquation has the good mobility energy, so must heat and its Heating temperature is controlled to the spray dish.Utilize electric heater unit to heat this spray dish by thermal radiation or thermal conduction, the tabular of spray dish is subjected to heat structure to be easy to accomplish to its equal heat phase and control.
The invention has the beneficial effects as follows:
1, can accomplish that in the industrialization continuous flow procedure shower nozzle stops up never, needn't change and clean, not can because of the former of spray dish thereby cause total system be forced to stop.
2, on spray dish and the contacted end face of molten materials, with spray disk center is the radial some structure grooves that have that wait angle of initial point, this structure groove can increase the effective heating surface of spray dish long-pending, can make fused solution and spray dish be tending towards rotation synchronously more and fragment into drop more uniformly to spray dish outer rim quick travel, after can making fused solution break away from simultaneously spraying disk body.
3, the rotation spray dish structure that the present invention relates to equally also adapts to other full-bodied, as to contain the chemical material of solid suspension insolubles granulation.
