Summary of the invention
Technical problem to be solved by this invention is to provide the capacitor stage phosphoric acid production device of the higher phosphoric acid product of a kind of energy production purity.
The technical solution adopted for the present invention to solve the technical problems is: capacitor stage phosphoric acid production device, comprise air compressor and combustion phosphorus hydration tower, comprise air purification tower and auxiliary air scavenging tower, the exit end of described air compressor communicates with the bottom of air purification tower, be filled with air purifying preparation in air purification tower, the air purification tower exit end of air purification tower be arranged at the phosphorus rifle firing phosphorus hydration tower inner tip and communicate; Described auxiliary air scavenging tower is communicated with combustion phosphorus hydration tower by auxiliary air scavenging tower exit end; The sidewall of described combustion phosphorus hydration tower is provided with deionized water nozzle.
Further, the top of auxiliary air scavenging tower inside is provided with auxiliary purification shower nozzle, and described auxiliary purification shower nozzle communicates with the ionized water induction pipe of deionized water nozzle.
Further, the bottom of auxiliary air scavenging tower is provided with auxiliary air scavenging tower inlet mouth, and auxiliary air scavenging tower exit end is arranged at the top of auxiliary air scavenging tower.
Further, the air purifying preparation in described air purification tower is ionized water.
Further, described auxiliary air scavenging tower exit end is arranged at combustion phosphorus hydration tower top end, and described auxiliary air scavenging tower exit end is distributed in around the phosphorus rifle of combustion phosphorus hydration tower.
Further, described deionized water nozzle is distributed on the sidewall of combustion phosphorus hydration tower.
The invention has the beneficial effects as follows: the product that the present invention produces is the phosphoric acid of capacitor stage, so first improve in the burning of yellow phosphorus: one is filtered by air purification tower by the air with yellow phosphorus mixed firing, what ensure with the air of yellow phosphorus mixed firing is pure; Two is set up auxiliary air scavenging tower, and described auxiliary air scavenging tower is used for for providing more sufficient oxygen atmosphere during yellow phosphorus burning, ensures the Thorough combustion of yellow phosphorus.Above two inventive points can allow the burning of yellow phosphorus be ensured fully, and the Vanadium Pentoxide in FLAKES particle purity obtained also improves greatly.Supreme on this basis, by arranging deionized water nozzle on the sidewall of combustion phosphorus hydration tower, ionized water can be sprayed in combustion phosphorus hydration tower uniformly by deionized water nozzle, allow the Vanadium Pentoxide in FLAKES particle obtained after the burning of yellow phosphorus realize mixing uniformly with ionized water.The combination of these two production stages substantially increases purity and the homogeneity of final yellow phosphorus product, can realize efficient production capacitor stage yellow phosphorus solution.The present invention is particularly suitable for producing with in the capacitor stage yellow phosphorus solution highly purified yellow phosphorus solution that is representative.

Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
Capacitor stage phosphoric acid production device as shown in Figure 1, comprise air compressor 7 and combustion phosphorus hydration tower 3, comprise air purification tower 1 and auxiliary air scavenging tower 2, the exit end of described air compressor 7 communicates with the bottom of air purification tower 1, be filled with air purifying preparation 4 in air purification tower 1, the air purification tower exit end 11 of air purification tower 1 be arranged at the phosphorus rifle 6 firing phosphorus hydration tower 3 inner tip and communicate; Described auxiliary air scavenging tower 2 is communicated with combustion phosphorus hydration tower 3 by auxiliary air scavenging tower exit end 21; The sidewall of described combustion phosphorus hydration tower 3 is provided with deionized water nozzle 31.
When practical application, in conjunction with practical experience, liquid yellow phosphorus is that Cemented filling by communicating with phosphorus rifle 6 is to phosphorus rifle 6 place.After entering into air compressor 7 with the air of yellow phosphorus mixed firing by air compressor inlet mouth 71, directly enter into the bottom of air purification tower 1, then after the filtration of air purifying preparation 4, enter into phosphorus rifle 6 place by air purification tower exit end 11, thus realize the burning with liquid phosphor.Namely the Vanadium Pentoxide in FLAKES obtained that burns is positioned at combustion phosphorus hydration tower 3.Sufficient oxygen is had in order to allow the burning situation of yellow phosphorus, thus improve the purity of Vanadium Pentoxide in FLAKES particle, the present invention has also set up auxiliary air scavenging tower 2, air in described auxiliary air scavenging tower 2 enters in combustion phosphorus hydration tower 3 by auxiliary air scavenging tower exit end 21, greatly can improve the oxygen content in combustion phosphorus hydration tower 3, thus ensure yellow phosphorus Thorough combustion.After completing above-mentioned Thorough combustion, the deionized water spray that ionized water induction pipe 32 transports can go out by deionized water nozzle 31 of the present invention, thus allows Vanadium Pentoxide in FLAKES particle fully be dissolved in ionized water, and finally obtains the very high capacitor stage phosphoric acid solution of purity.
Also be guaranteed to allow the purity entering into the air of combustion phosphorus hydration tower 3 by auxiliary air scavenging tower 2, can arrange auxiliary purification shower nozzle 5 on the top of auxiliary air scavenging tower 2 inside, described auxiliary purification shower nozzle 5 communicates with the ionized water induction pipe 32 of deionized water nozzle 31.As shown in Figure 1, the air that auxiliary air scavenging tower inlet mouth 22 place enters can filter by the ionized water that auxiliary purification shower nozzle 5 sprays, thus further improves the purity of final phosphoric acid product.
As further improvement of these options, can select bottom auxiliary air scavenging tower inlet mouth 22 being arranged at auxiliary air scavenging tower 2, auxiliary air scavenging tower exit end 21 is arranged at the top of auxiliary air scavenging tower 2.Such improvement can improve the filter effect of ionized water to air, allows product quality be improved.
In order under the prerequisite ensureing quality product, accomplish the simplification of equipment variety of raw material, the air purifying preparation 4 in described air purification tower 1 can be chosen as ionized water.Contaminant filter in air can well fall by ionized water, and ionized water can directly be obtained by ionized water induction pipe 32 place.
In order to the supply allowing the burning of yellow phosphorus obtain sufficient oxygen further, described auxiliary air scavenging tower exit end 21 can be arranged at combustion phosphorus hydration tower 3 top, and described auxiliary air scavenging tower exit end 21 is distributed in around the phosphorus rifle 6 of combustion phosphorus hydration tower 3.As shown in Figure 1, the air like this through auxiliary air scavenging tower exit end 21 can create sufficient oxygen-enriched environment for aflame yellow phosphorus, not only increases yellow phosphorus raw material availability, also substantially increases the purity of final phosphoric acid solution.
Based on same design, also described deionized water nozzle 31 can be distributed on the sidewall of combustion phosphorus hydration tower 3.As shown in Figure 1, the water smoke that such improvement can allow the ionized water that sprays be formed evenly, better can form the capacitor stage phosphoric acid solution that quality is higher.
