Background technology
Existing phosphoric acid, especially in the production process of capacitor stage phosphoric acid, the primary industry yellow phosphorus adopting is all directly by pipeline, to be delivered in phosphoric acid production equipment combustion phosphorus hydration tower, by spray burning after described yellow phosphorus and air mixed, obtain Vanadium Pentoxide in FLAKES particle, and finally obtain phosphoric acid solution.But such technique is because yellow phosphorus raw material is without any purifying treatment, in industrial yellow phosphorus, containing the impurity such as heavy metal, impurity, organism also can be along with entering into final phosphoric acid product.Therefore such mode of production can affect the purity of final phosphoric acid product.Especially for capacitor stage phosphoric acid product, such production technique is difficult to the qualified product of producing of efficient stable.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of capacitor stage phosphoric acid yellow phosphorus purification device that industrial yellow phosphorus raw material is purified.
The technical solution adopted for the present invention to solve the technical problems is: capacitor stage phosphoric acid yellow phosphorus purification device, comprise that inside is provided with the rinse tank of whipping appts, yellow phosphorus storage tank, pickling tank, melts phosphorus groove and is provided with the water washing cleaning pot of ionized water entrance, described yellow phosphorus storage tank communicates with rinse tank by being arranged at the yellow phosphorus submerged pump of yellow phosphorus storage tank inner bottom part, described pickling tank communicates with rinse tank by being arranged at the pickling submerged pump of pickling tank inner bottom part, rinse tank communicates with water washing cleaning pot, described water washing cleaning pot by yellow phosphorus output tube with melt phosphorus groove and communicate.
Further, the whipping appts in described rinse tank is the stirring rake that is arranged at rinse tank bottom.
Further, described yellow phosphorus output tube is arranged at the stage casing of water washing cleaning pot.
Further, the bottom of water washing cleaning pot is provided with pickle solution relief outlet.
Further, in rinse tank, be provided with temperature-detecting device.
Further, described ionized water entrance is arranged at the top of water washing cleaning pot.
The invention has the beneficial effects as follows: first the present invention is transported to liquid industrial yellow phosphorus in rinse tank, to stir rinsing by yellow phosphorus submerged pump, when temperature reaches 70 to 80 degrees Celsius, start pickling submerged pump, the pickle solution in pickling tank is pumped in rinse tank and carries out mix and blend with yellow phosphorus raw material.After stirring, the liquid in rinse tank is passed in water washing cleaning pot and is heated, and the ion film water that simultaneously passes into 70 to 80 degrees Celsius of temperature by ionized water entrance rinses, until remove completely in yellow phosphorus after residual acid solution, can obtain the pure yellow phosphorus raw material for the production of capacitor stage phosphoric acid.The present invention's practicality that is skillfully constructed, is specially adapted to purify the yellow phosphorus for the production of capacitor stage phosphoric acid, thereby guarantees the quality of the capacitor stage phosphoric acid product that finally obtains.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, be labeled as: yellow phosphorus storage tank 1, yellow phosphorus submerged pump 11, rinse tank 2, whipping appts 21, water washing cleaning pot 3, yellow phosphorus 31, yellow phosphorus output tube 311, ionized water 32, pickle solution 33, pickle solution relief outlet 331, ionized water entrance 34, pickling tank 4, pickling submerged pump 41, melt phosphorus groove 5.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
Capacitor stage phosphoric acid yellow phosphorus purification device as shown in Figure 1, comprise that inside is provided with the rinse tank 2 of whipping appts 21, yellow phosphorus storage tank 1, pickling tank 4, melts phosphorus groove 5 and is provided with the water washing cleaning pot 3 of ionized water entrance 34, described yellow phosphorus storage tank 1 communicates with rinse tank 2 by being arranged at the yellow phosphorus submerged pump 11 of yellow phosphorus storage tank 1 inner bottom part, described pickling tank 4 communicates with rinse tank 2 by being arranged at the pickling submerged pump 41 of pickling tank 4 inner bottom parts, rinse tank 2 communicates with water washing cleaning pot 3, described water washing cleaning pot 3 by yellow phosphorus output tube 311 with melt phosphorus groove 5 and communicate.
When reality use is of the present invention, the industrial yellow phosphorus first needs being cleaned is poured in yellow phosphorus storage tank 1, and first described liquid industrial yellow phosphorus is transported in rinse tank 2 through yellow phosphorus submerged pump 11, and heats up through the stirring of whipping appts 21.General, when temperature reaches to 70 to 80 degrees Celsius, the pickling submerged pump 41 that starts pickling tank 4 is input to pickle solution in rinse tank 2, mixes, and removed and be take the impurity that sulfide is representative by pickle solution with yellow phosphorus.Next, the yellow phosphorus that contains pickle solution is passed in water washing cleaning pot 3, and yellow phosphorus solution is heated.Meanwhile, by ionized water entrance 34, pass into ionized water the yellow phosphorus that contains pickle solution is carried out to rinsing.Finally, at the interior material that can form three aspects of water washing cleaning pot 3: be positioned at undermost pickle solution 33, be positioned at middle layer yellow phosphorus 31, be positioned at the ionized water 32 of the superiors.Now, only need yellow phosphorus 31 is input to and melt phosphorus groove 5 by yellow phosphorus output tube 311, the yellow phosphorus starting material after finally can being purified in melting phosphorus groove 5 be for the production of capacitor stage phosphoric acid.
In order to simplify the structure of whipping appts 21, the whipping appts 21 in described rinse tank 2 can be chosen as to the stirring rake that is arranged at rinse tank 2 bottoms.As shown in Figure 1, the stirring rake after simplification can guarantee mixing of industrial yellow phosphorus and ionized water, and is convenient to the dismounting maintenance in later stage.
Because the yellow phosphorus 31 obtaining in water washing cleaning pot 3 is generally the stage casing that is positioned at water washing cleaning pot 3, described yellow phosphorus output tube 311 can be arranged to the stage casing of water washing cleaning pot 3, can easylier more fully yellow phosphorus 31 be discharged again like this.
In order timely the pickle solution of water washing cleaning pot 3 bottoms to be discharged, pickle solution relief outlet 331 can be set in the bottom of water washing cleaning pot 3.As shown in Figure 1, yellow phosphorus after ionized water rinses, its pickle solution containing becomes branch to be deposited in water washing cleaning pot 3 bottoms, sets up after pickle solution relief outlet 331, can timely described pickle solution be discharged, finally for repetitious ionized water rinses, provide technical guarantee.
Due to the requirement having when starting input pickle solution aspect temperature, so can be at the interior set temperature proofing unit of rinse tank 2.The temperature-detecting device of setting up can go out the interior Temperature Feedback of rinse tank 2 comparatively accurately, can realize like this automatization control that pickle solution adds, and improves level of automation of the present invention.
In order to make ionized water better to the developing result of yellow phosphorus, described ionized water entrance 34 can be arranged to the top of water washing cleaning pot 3.Such improvement can allow ionized water rinse more fully yellow phosphorus 31, also allows the purity of the yellow phosphorus product that finally obtains higher.
The resulting pure yellow phosphorus product of the present invention is the starting material of production capacitor stage phosphoric acid.Through processing of the present invention, purification, yellow phosphorus can directly be passed among next step operation, and the quality of the capacitor stage phosphoric acid product finally obtaining also can be greatly increased.
