Abstract
The utility model discloses a system for purifying potassium dihydrogen phosphate. The system comprises a dissolution reaction kettle (1), a filtering device (2), a cooling tank (3) and a centrifugal water removing device (4), wherein potassium dihydrogen phosphate powder is dissolved in the dissolution reaction kettle and then flows into the filtering device (2), then a potassium dihydrogen phosphate solution obtained after filtration by the filtering device (2) enters the cooling tank (3) to obtain a solid-solution state potassium dihydrogen phosphate solution, and then the solid-solution state potassium dihydrogen phosphate solution enters the centrifugal water removing device (4) for centrifugal water removal. The system is simple in structure, can efficiently purify the potassium dihydrogen phosphate solution, and has high purification efficiency.
Description
Technical field
The utility model relates to a kind of potassium primary phosphate purification system, belongs to potassium primary phosphate purification equipment technical field.
Background technology
The purity of potassium primary phosphate is higher, the crystal of growth can be larger, for example, when making eyeglass, just mean that also the eyeglass of doing can be larger, the light beam that can pass through within the unit time like this can be more, and light beam through after this crystal eyeglass a cataclysm can occur, it can be heated up, be exactly traditional laser.
Therefore, the purity of potassium primary phosphate is extremely important.It is free metal ion with in the potassium primary phosphate that the powder of potassium dihydrogen phosphate crystal is purified, and comprises other impurity, effectively is controlled at below the 0.02ppm, makes its growth to crystal have controllability, makes crystal become pure and physical property is fixed.
The content of at present domestic potassium primary phosphate detrimental impurity there is no at present simple and reliable method potassium primary phosphate is purified below 10ppm.The purification water-soluble reagent is generally used the method for recrystallization, and utilize impurity in crystal and in the solvent difference of segregation coefficient reaches the purpose of purifying.
The utility model content
The purpose of this utility model provides a kind of system that can effectively purify to potassium dihydrogen phosphate.
In order to reach above-mentioned technical purpose, the technical solution of the utility model is: a kind of potassium primary phosphate purification system, it comprises solubilizing reaction still, filtration unit, cooling tank and centrifugal water trap, inflow filter after the potassium primary phosphate powder dissolves in the solubilizing reaction still, potassium dihydrogen phosphate enters the potassium dihydrogen phosphate that cooling tank obtains solid solution condition behind the device after filtration, and the potassium dihydrogen phosphate of solid solution condition enters centrifugal anhydrating in the centrifugal water trap.
Described filtration unit is by the membrane filtration potassium dihydrogen phosphate.
Described centrifugal water trap is whizzer.
The utility model is simple in structure, can carry out purification operations to potassium dihydrogen phosphate efficiently, and purification efficiency is high.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the schematic diagram of the utility model system.
Embodiment
As shown in Figure 1, the utility model system comprises dissolving, filtration, crystallisation by cooling and the centrifugal step of anhydrating.
Dissolving step carries out in solubilizing reaction still 1, and the potassium primary phosphate powder is dissolved in the ultrapure water.Also comprise the steps such as heating, stirring in this process, to obtain higher efficient.
Allow the dissolving after potassium dihydrogen phosphate inflow filter 2 in, the filter membrane of filtration unit 2 is with solution filter, this process is mainly removed particle diameter greater than the impurity of 0.1 μ m.
Potassium dihydrogen phosphate after the filtration enters and carries out the crystallisation by cooling processing in the cooling tank 3, passes through the agitator arm stirred solution in this process to obtain higher crystallisation by cooling efficient.
Obtain the potassium dihydrogen phosphate of solid solution condition behind cooling tank 3 crystallisation by cooling, the centrifugal water trap 4 of at last this solution being put into whizzer one class carries out centrifugal anhydrating.
Just obtain evengranular potassium primary phosphate after centrifugal the anhydrating.
Above-described embodiment limits the utility model never in any form, and every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops in the protection domain of the present utility model.
