[0021] This embodiment describes the specific structure of an apparatus for producing sodium phosphate ore from sodium-containing water bodies, as detailed in the following reference. Figure 1 As shown, an apparatus for producing sodium phosphate ore from sodium-containing water includes:

[0022] Example 1

[0023] Sedimentation tank 1 is provided with an inlet 8. Sedimentation tank 1 is connected to sedimentation tank 2 and evaporation concentration tank 3 through pipes. Evaporation concentration tank 3 is connected to dissolving tank 4 through pipes. Dissolving tank 4 is provided with a sample inlet 9. Dissolving tank 4 is connected to heating reaction tank 5 through pipes. Heating reaction tank 5 is connected to cooling tank 6 through pipes. Cooling tank 6 is connected to solid-liquid separation device 7 through pipes. Solid-liquid separation device 7 is provided with a discharge outlet 11 and a sample outlet 10.

[0024] Settling tank 1 settles sodium-containing water. The settled solids enter sedimentation tank 2, and the supernatant enters evaporation and concentration tank 3. The sodium-containing liquid phase after evaporation and concentration enters dissolution tank 4. After dissolution in dissolution tank 4, the liquid phase is transferred to heating reaction tank 5. After heating and full reaction, it is transferred to cooling tank 6 for crystallization. After crystallization, both solid and liquid phases are transferred to solid-liquid separation device 7 for solid-liquid separation.

[0025] Salt lake brine is injected into settling tank 1 to settle the suspended solids in the water to the bottom of the tank and transfer them to sedimentation tank 2. The supernatant enters evaporation and concentration tank 3 through the outlet of settling tank 1. The sodium-containing liquid phase after evaporation and concentration is transferred to dissolution tank 4 through a pipeline. Diammonium hydrogen phosphate is added and stirred thoroughly until the salt dissolves. The liquid phase is then transferred to heating reaction tank 5, heated and reacted fully. Then, it is slowly transferred to cooling tank 6 while still hot to ensure uniform and sufficient cooling. After crystallization, both solid and liquid phases are transferred to solid-liquid separation device 7. After separating the solid phase, it is sprayed with fresh water and dried to obtain sodium phosphate ore. The liquid phase yields another salt-containing concentrated solution.

[0026] Among them, a valve is installed at the inlet 8 of the sedimentation tank 1 to control the injection and speed of sodium-containing water. A valve is installed on the pipeline between the sedimentation tank 1 and the evaporation concentration tank 3 to control the outflow and speed of the supernatant. A valve is installed on the pipeline between the sedimentation tank 1 and the sedimentation tank 2 to control the outflow of sediment.

[0027] Furthermore, the bottom of the evaporation concentration tank 3 is equipped with a heating element, and the pipe between the evaporation concentration tank 3 and the dissolving tank 4 is equipped with a valve to control the outflow and speed of the concentrate. The evaporation mode can be natural evaporation or heated evaporation, with a heating temperature range of 80℃. The evaporation time in the evaporation concentration tank 3 can be determined according to the volume of the supernatant and the evaporation method. The Na+ concentration per ton of concentrate is 46 kg.

[0028] It is worth noting that the dissolving tank 4 is equipped with a stirring device, and the stirring speed is controlled at 200 revolutions per minute. The sample inlet 9 of the dissolving tank 4 is equipped with a valve to control the sample injection speed. The pipeline between the dissolving tank 4 and the heating reaction tank 5 is equipped with a valve to control the outflow and speed of the liquid phase. Diammonium hydrogen phosphate and ammonium dihydrogen phosphate are added to the dissolving tank 4 in a ratio of 2:1. The ratio of phosphorus atoms to sodium ions in the solution can be 1:1.

[0029] In addition, the heating reaction tank 5 is equipped with a heating element with a heating temperature range of 80°C. A valve is installed on the pipe between the heating reaction tank 5 and the cooling tank 6 to control the outflow and speed of the hot reaction liquid. The heating reaction time in the heating reaction tank 5 is 1 hour.

[0030] More importantly, the cooling pool 6 is equipped with a refrigeration element with a cooling temperature range of 10°C. The pipeline between the cooling pool 6 and the solid-liquid separation device 7 is equipped with a valve to control the sample discharge and speed. The cooling pool 6 should control the liquid phase flow rate to 0.1 tons per hour and the cooling time in the cooling pool 6 to 30 minutes.

[0031] Furthermore, the sample outlet 10 of the solid-liquid separation device 7 is equipped with a valve to control the product sampling and speed.

[0032] The final solid product is sodium phosphate rock with a purity of 99%. The Na+ conversion rate in the salt lake brine can reach 90%. The resulting liquid phase is a concentrated NH4+ solution containing impurities.

[0033] Example 2

[0034] The apparatus is the same as in Example 1, except that the sodium-containing water is papermaking wastewater. After pretreatment and sedimentation, the wastewater enters evaporation and concentration tank 3, where it is heated to 50°C and concentrated to a Na+ concentration of 40 kg / ton of concentrate. Aluminum phosphate and aluminum hydrogen phosphate are added to dissolving tank 4 in a 1:3 ratio, with a phosphorus atom to sodium ion ratio of 1:1. The stirring speed in dissolving tank 4 is 150 rpm, and the heating temperature in the reactor is 90°C for 40 minutes. After the reaction, the liquid phase flows into cooling tank 6 at a rate of 0.1 tons / hour, cooling to 0°C for 30 minutes. The synthesized product is sodium aluminum phosphate with a purity of 80%, achieving a Na+ conversion rate of up to 90% in the papermaking wastewater. The resulting liquid phase is a concentrated Al3+ solution containing impurities.

[0035] Example 3

[0036] The apparatus is the same as in Example 1, except that the sodium-containing water is papermaking wastewater. After pretreatment and sedimentation, the wastewater enters evaporation and concentration tank 3, where it is heated to 50°C and concentrated until the Na+ concentration in each ton of concentrate is 69 kg. Beryllium phosphate is added to dissolving tank 4, with a phosphorus atom to sodium ion ratio of 1:1. The stirring speed in dissolving tank 4 is 100 rpm, the heating temperature in the reactor is 80°C, and the reaction time is 40 minutes. After the reaction, the liquid phase flows into cooling tank 6 at a rate of 0.1 tons per hour, where it is cooled to -10°C for 60 minutes. The synthesized product is sodium beryllium phosphate with a purity of 99%, and the Na+ conversion rate in the papermaking wastewater can reach 20%.

[0037] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation.
