[0003] In the prior art, the method for preparing sodium carbonate powder usually adopts chemical precipitation-crystallization method: taking industrial sodium carbonate as raw material, preparing sodium carbonate solution, performing precipitation treatment on anions and cations, crystallizing the sodium carbonate solution, removing water to obtain sodium carbonate powder. However, the method is complicated in operation, new impurities may be introduced in the precipitation process, the purity is low, and the powder is easy to aggregate and block, thereby limiting the application. In addition, the commonly used method for preparing sodium carbonate powder is ion exchange-crystallization method: taking industrial sodium carbonate as raw material, preparing sodium carbonate solution, performing adsorption treatment on anions, crystallizing the sodium carbonate solution, removing water to obtain purified sodium carbonate. However, the obtained sodium carbonate is complicated in operation and high in cost, and only part of anion impurities can be removed in the adsorption process, and cation impurities still exist in the sodium carbonate, thereby resulting in low product purity, poor flowability of the powder due to aggregation, low utilization rate, and inability to meet the market demand for high-purity, high-utilization, low-cost spherical sodium carbonate powder.

[0037] The spray rounding device is used to prepare spherical sodium carbonate powder, and specifically includes the following steps:

[0038] S1: prepare saturated sodium carbonate solution;

[0039] Accurately take 27 parts of sodium carbonate powder, so that the mass ratio of sodium carbonate powder to pure water is 27:100, and add 100 parts of pure water in the stirring barrel. Turn on the stirrer, adjust the stirring speed to 20Hz~30Hz, then add the sodium carbonate powder gradually, and add again after the solution becomes clear each time. After the sodium carbonate is added, adjust the stirring speed to 45Hz~55Hz for dissolution.

[0040] or using the following method to prepare saturated sodium carbonate solution: first prepare unsaturated sodium carbonate solution, use pneumatic diaphragm pump to add unsaturated sodium carbonate solution to the stirring barrel containing sodium carbonate powder, adjust the stirring speed to 45-55 Hz for dissolution, use a graduated cylinder to measure the volume of 100 parts of sodium carbonate solution, measure the mass of the 100 parts of sodium carbonate solution, the density of the sodium carbonate solution is the ratio of mass to volume, when the density of the sodium carbonate solution is 1.25 g / cm 3 -1.28 g / cm 3 , stop adding unsaturated sodium carbonate solution to the stirring barrel.

[0041] Step S2: filter the dissolved sodium carbonate solution;

[0042] Use a pneumatic diaphragm pump to draw the completely dissolved sodium carbonate solution in the stirring barrel into a ceramic membrane filter, and after the sodium carbonate solution is filtered in the ceramic membrane filter, it flows into the material barrel. When the sodium carbonate solution in the stirring barrel is exhausted, wait for 10 s, then close the air valve of the pneumatic diaphragm pump. Prepare pure water, put the feed pipe of the pneumatic diaphragm pump into the pure water, put the discharge pipe into the stirring barrel, open the air valve, and completely discharge the residual sodium carbonate solution in the pneumatic diaphragm pump.

[0043] Step S3: discharge the filtered sodium carbonate solution from the material barrel and clean the ceramic membrane filter;

[0044] Turn on the cooling water switch and open the switch of the ceramic membrane filter, and then pour the filtered sodium carbonate solution in the material barrel into the sodium carbonate solution barrel for standby. After all the filtered sodium carbonate solution is discharged, pour the unfiltered sodium carbonate solution remaining in the ceramic membrane filter into the collection barrel for subsequent unified treatment. Pour pure water into the material barrel, open the switch of the ceramic membrane filter, and after the equipment runs for 10 min, close the switch, discharge the residual filtrate and pure water in the material barrel, add pure water again, and repeat the above cleaning steps. Finally, turn off all switches.

[0045] Step S4: turn on the switch of the spray rounding machine, and after the heating chamber reaches the specified temperature, turn on the switch of the peristaltic pump to start producing sodium carbonate powder;

[0046] Open the ventilation pipe switch of the spray roller compactor, replace the filter cotton. After confirming that the equipment is normal, turn on the circulating cooling water machine, open the total switch of the spray roller compactor, turn on the induced draft fan, and then turn on the atomizer switch. From the observation window, observe whether the atomizer rotates. If it cannot rotate normally, turn off the atomizer switch and the total switch of the spray dryer. Insert your hand into the observation window and gently push the atomizer counterclockwise. After withdrawing your hand, close the observation window. Reopen the total switch of the spray dryer and the atomizer switch. Check again whether the atomizer can rotate normally. If it still cannot rotate normally, stop the machine and contact the maintenance personnel. If it rotates normally, turn on the heating switch and observe the real-time temperature displayed on the operation panel. When the current temperature of the equipment reaches 210℃-250℃ and the outlet temperature stabilizes to 90℃-120℃, wait for 30 minutes. Put the feeding pipe into the sodium carbonate solution. Then turn on the atomizer. After 30 seconds, when the atomizer speed reaches 15000r / min-19000r / min, turn on the peristaltic pump switch and start producing sodium carbonate powder. The sodium carbonate powder is rolled and formed at a speed of 20r / min-40r / min. If the material is taken out in the middle of the process, close the butterfly valve, take out the feeding pipe from the sodium carbonate solution, and keep the atomizer rotating. After the atomizer stops spraying material, the material can be taken out.

[0047] Step S5: After the production of sodium carbonate powder is completed, close the butterfly valve. When the temperature in the drying chamber drops below 60℃, close the peristaltic pump. Package and seal the product sodium carbonate powder.

[0048] After the production of sodium carbonate powder is completed, remove the collection tank and place a material basin under the collection tank to obtain spherical sodium carbonate powder with a diameter of 200μm-500μm. Take out the feeding pipe from the sodium carbonate solution, turn off the heating switch, and put the feeding pipe into a pure water bucket. Run until the temperature of the spray roller compactor cavity drops below 60℃. Take out the feeding pipe. After the pure water in the feeding pipe is completely drained, turn off the peristaltic pump. Turn on the fume hood exhaust fan. Package the sodium carbonate in the fume hood. Immediately after packaging is completed, seal the package. Finally, turn off the fume hood exhaust fan.

[0049] Step S6: Equipment cleaning and finishing work

[0050] After the temperature of the equipment drops to room temperature, open the observation window and collect the sodium carbonate powder near the observation window with a material basin. After collection is completed, insert your hand into the observation window. Gently wipe the atomizer with wet dust-free cotton. After the atomizer is cleaned, wash the inner wall 3-4 times with pure water. Finally, use an air gun or a vacuum cleaner to collect the sodium carbonate powder scattered around the machine and on the ground.
