Every circle annular air supply unit 5 is made up of 20-40 typhoon machine 3, and every circle annular air supply unit 5 all is equipped with and is used for the unified variable-frequence governor of regulating air quantity.
The utlity model has following advantage:
1, method technology compactness of the present utility model, product shaping are good, less investment, energy consumption is low, it produces negative pressure upwards by many horizontal rows are installed at granulation formation tower middle part on the one hand to the wind cutting air-blast device and at many exhaust equipments of cat head installation, fast unnecessary heat is discharged outside the tower on the other hand, reduced the set time of compound fertilizer granules significantly, reduced the height and the diameter of granulation formation tower, the cost of can reducing investment outlay greatly reduces running cost.
2, compare with freezing tower with existing low tower and can reduce investment 50%-70%, simultaneously industrial scale can be regulated as required, and is changeable.
3, can produce the composite fertilizer of high, normal, basic different concns, it is very convenient to change prescription, the formula rate scope is big, can regulate air output by the variable frequency adjustment device for the composite fertilizer of different proportionings and will adjust to suitable scope cooling time, prevents that cold-peace from cooling off the not generation of foot phenomenon.
4, can not produce the dust wall sticking phenomenon, need not periodic cleaning tower wall, the compound fertilizer slurry particle can make that with vortex shape slow decline in body of the tower dust descends with particle, can not produce present dust raising phenomenon.
5, the good evenness of product, yield rate can be up to more than 99%, and handling.
6, can under all weather conditions, work, solved under high temperature that existing processes exists, the super-humid conditions can't ordinary production contradiction, can be under hot and humid condition round-the-clock ordinary production.
7, energy consumption is low, has reduced tower height on the one hand, has reduced the energy consumption of mass transport, by adopting energy-conservation gas blower, can significantly reduce energy loss on the other hand.

Embodiment
Following structure drawings and Examples are further described the utility model.
The wind-cooling crystallization granulation device of a kind of full-fusing composite fertilizer, as shown in Figure 1, 2, it comprises prilling tower 1, rotating granulation head 2, blower fan 3, vacuum fan 4, this tower height of making material tower 1 is a 15-50 rice, tower diameter is a 6-12 rice, and rotating granulation head 2 is installed in prilling tower 1 inside top center position, is vertically installed with 4-8 platform vacuum fan 4 around the top of prilling tower 1, rotating granulation head 2, so that the heat in the tower is discharged, the blast inlet of vacuum fan 4 communicates with the inner chamber of prilling tower 1; Be that the annular air supply unit 5 that 3-5 circle, every circle are made up of 20-40 typhoon machine 3 is installed on the prilling tower body of the tower of (as 4 meters positions) below 4 meters in distance rotating granulation head 2 vertical ranges, the air output of every typhoon machine 3 and air supply velocity can be selected with reference to the relevant design handbook according to kind, speed of cooling and the output of composite fertilizer, and the distance between the described annular air supply unit 5 is advisable with 1.5-4 rice.In order to obtain ideal vortex effect, slow down the lowering speed of slip, the slurry that comes out from prilling head is cooled off rapidly, therefore the air supply direction of blower fan 3 should reasonably be controlled, the angle α of the air supply direction of blower fan 3 and horizontal plane can select between the 15-45 degree, and the angle β between the mounting points tower diameter line of place can select between the 80-85 degree.Each annular air supply unit 5 all has volume adjusting apparatus (as variable-frequence governor) separately so that air output is regulated in unification.
Air output when specifically implementing in addition, can be determined according to output and tower diameter.
It is all same as the prior art that the utility model does not relate to part.
The method that matches with the utility model may further comprise the steps:
The first step is 15-50 with the composite fertilizer's slip under the full-fusing state from being positioned at tower height, and tower diameter is to spray in the rotating granulation head at top of prilling tower of 6-12 rice;
Second step, first group of cooling blower of drying in tower is installed around the prilling tower body of the tower that from the prilling head vertical range is the position that (contains 4 meters) below 4 meters, making the air-out direction of every typhoon machine and the angle of horizontal plane is the 15-45 degree, with the diameter angle be the direction of 80-85 degree to tower to carrying cooling wind, the control air supply velocity is the 2-10 meter per second, blast is 100-400Pa, to guarantee speed of cooling, and the reasonable disposition by blower fan (is promptly adjusted the direction of blower fan air-supply, angle) make cooling in tower, form the vortex shape air curtain with wind by the blower fan air-supply, thereby slow down the lowering speed of the particulate state slip that sprays in the rotating granulation head, each face of slip is fully contacted with wind with the cooling that blower fan is sent here, make its surperficial rapid crystallization; The vacuum fan that ventilates and produce negative pressure meanwhile has been installed on the granulation cat head, has been extracted out the heat of slurry in the tower outside the tower fast;
The 3rd step, below first group of cooling blower every be provided with for 1.5-4 rice one group, altogether design two groups or more, go on foot identical cooling air unit with second, so that the basic crystal grain that is shaped further cools off after the cooling of the first cooling air unit, after being deposited at the bottom of the tower, at the bottom of tower, obtain granular complex fertilizer;
In the 4th step, above-mentioned the 3rd granular complex fertilizer that obtains of step is sent tower by conveying belt carry out naturally cooling outward and get final product.
