Abstract
The utility model discloses a kind of production equipment of highly water-soluble phosphorus S-based compound fertilizer, comprise mother liquor holding tank and dilute phosphoric acid storage tank, these two storage tanks are all connected to conversion tank, and the discharge port of conversion tank connects tubular reactor, flashing apparatus and spray granulation drier successively; Described flashing apparatus is also connected with washer, and spray granulation drier is also connected with venturi scrubber, and washer and venturi scrubber are all connected to emptying chimney.The S-based compound fertilizer water-soluble phosphorus adopting this device to produce and original S-based compound fertilizer water-soluble phosphorus will exceed more than 5%, mainly make use of water-soluble phosphorus content high in the industrial monoammonium phosphate mother liquor stored in mother liquor holding tank; Can obtain outward appearance more mellow and fuller, the more uniform compound manure of granularity, and S-based compound fertilizer device easily operates in granulation process, production control is more steady, and the production capacity of device is played to greatest extent.
Description
Technical field
The utility model belongs to chemical production field, is specifically related to a kind of production equipment of highly water-soluble phosphorus S-based compound fertilizer.
Background technology
In recent years, along with putting into operation of large quantities of S-based compound fertilizer device, S-based compound fertilizer product has been tending towards saturated, Market competition.Add raw-material lasting rise in price, client has higher requirement to water-soluble phosphorus aspect, and the profit of enterprise is compressed further.Therefore ensure that compound fertilizer facility quality product has very important realistic meaning.
Existing spray granulating method is not high at the S-based compound fertilizer water-soluble phosphorus content produced of dilute phosphoric acid of use low-grade high-magnesium-phosphorus ore to produce 20% ~ 25%, generally between 80 ~ 84%, can not meet the demand of client.
Summary of the invention
The purpose of this utility model is for above problem, provides a kind of production equipment of highly water-soluble phosphorus S-based compound fertilizer, can overcome the present situation that current S-based compound fertilizer water-soluble phosphorus is not high, optimizes quality product and the production equipment of S-based compound fertilizer.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of production equipment of highly water-soluble phosphorus S-based compound fertilizer, it is characterized in that: comprise mother liquor holding tank and dilute phosphoric acid storage tank, these two storage tanks are all connected to conversion tank, and the discharge port of conversion tank connects tubular reactor, flashing apparatus and spray granulation drier successively; Described flashing apparatus is also connected with washer, and spray granulation drier is also connected with venturi scrubber, and washer and venturi scrubber are all connected to emptying chimney.
Shurry pump is provided with between described flashing apparatus and spray granulation drier.
Described conversion tank also connects vitriol oil storage tank and Repone K storage tank by pipeline.
Described device also comprises screening plant; Main screening plant has roller grizzly, fluidized-bed cooler, cage crusher, worm conveyor, cooling air blower, finished product screen, and finished product before encapsulation equipment be also provided with cold wind kiln and coating machine.
Its concrete production method is
1) by weight, by being that the dilute phosphoric acid of 20% ~ 25% mixes by 2 ~ 4:1 with the mother liquor in industrial monoammonium phosphate device by mass concentration, with add 0.8-1.0 part mass concentration be 98% the vitriol oil, 0.5-1.5 part Repone K react 4 ~ 6h;
2) by the mixing solutions of gained after reaction in step 1) in carrying out through tubular reactor and ammonia with, the ammonia amount of use is regulated in time according to the viscosity of pH and slip, until slip pH is 1.10 ~ 1.50, then adopt spray granulation drier to carry out granulation, obtain the phosphorus S-based compound fertilizer that water-soluble phosphorus content is more than 88%.
The composition of the mother liquor in described industrial monoammonium phosphate device has nitrogen content 4 ~ 6%, available phosphorus content to be 16-20.Water-soluble P
2o
5in available phosphorus content, account for more than 99%, foreign matter content < 1%, and namely the effective constituent in the mother liquor utilized in the utility model be water-soluble P
2o
5.
Pass into saturation steam during described step 1) reaction, and constantly stir, control its temperature of reaction between 120 ~ 150 DEG C.
Described step 2) neutralization, in granulation process, the slip after neutralization and the specific gravity control of water 1.45 ~ 1.55, during granulation, the anterior temperature 300 ~ 600 DEG C of spray granulation drier, afterbody Wen Du≤60 DEG C.
Adopt this device and explained hereafter S-based compound fertilizer water-soluble phosphorus out and original S-based compound fertilizer water-soluble phosphorus to exceed more than 5%, mainly make use of water-soluble phosphorus content high in industrial monoammonium phosphate mother liquor; Can obtain outward appearance more mellow and fuller, the more uniform compound manure of granularity, and S-based compound fertilizer device easily operates in granulation process, production control is more steady, and the production capacity of device is played to greatest extent.Utilize this device can produce the sulphur based compound fertilizer of highly water-soluble phosphorus with low-grade high-magnesium-phosphorus ore, add the quality-advantage of sulphur based compound fertilizer, make competitive power commercially stronger.
Accompanying drawing explanation
Fig. 1 is the structural representation of the device that the utility model provides.
Embodiment
Further illustrate the utility model below in conjunction with embodiment, but the claimed scope of the utility model is not limited to the scope of embodiment statement.
As shown in Figure 1, a kind of production equipment of highly water-soluble phosphorus S-based compound fertilizer, comprise mother liquor holding tank 1 and dilute phosphoric acid storage tank 2, these two storage tanks are all connected to conversion tank 3, and the discharge port of conversion tank 3 connects tubular reactor 4, flashing apparatus 5 and spray granulation drier 6 successively; Described flashing apparatus 5 is also connected with washer 7, and spray granulation drier 6 is also connected with venturi scrubber 8, and washer 7 and venturi scrubber 8 are all connected to emptying chimney.
Further, shurry pump is provided with between described flashing apparatus 5 and spray granulation drier 6.
Further, described conversion tank 3 also connects vitriol oil storage tank and Repone K storage tank by pipeline.
Further, described device also comprises screening plant.
During use, by conversion tank mixing mother liquor, dilute phosphoric acid, the vitriol oil and Repone K, then enter in tubular reactor and react, then enter in flashing apparatus and carry out neutralizing and expansion drying, last spray granulation drier carries out granulating and drying, obtains phosphorus S-based compound fertilizer.Washer in device and venturi scrubber are all for reclaiming the objectionable impurities in tail gas.
