This design significantly enhances the stirring force and range, making the mixing between soda ash, circulating mother liquor and condensed water more sufficient and rapid, and the improvement of mixing efficiency helps to shorten the reaction time and improve production efficiency.

[0029] The alkali tank 5 is provided with a feed port 13, a chute 14 is provided on the feed port 13, a baffle 15 is slidably connected to the chute 14, the output end of the alkali tank 5 is fixedly connected to the second liquid pump 16, the output end of the second liquid pump 16 is fixedly connected to a clarification barrel 17, the end of the clarification barrel 17 away from the second liquid pump 16 is connected to a carbonizing tower 18, the output end of the carbonizing tower 18 is connected to a centrifugal cleaning machine 19, the output end of the centrifugal cleaning machine 19 is connected to a drying box 20, a CO2 purification component 21 is fixedly installed on the carbonizing tower 18, the first stirring rod 8 rotates in the alkali tank 5, The connecting seat 6 is located on the side of the alkali tank 5 away from the feed port 13, and the feed port 13 is obliquely arranged on the alkali tank 5. The components whose working principles are not mentioned in this application are all existing technologies that are known and easily available in the art. This article only uses them and does not improve them, so the working principle of this technology is not explained. The CO2 gas used for the carbonization reaction is purified to remove impurities therein, thereby improving the purity and cleanliness of the CO2 gas. This not only enhances the efficiency of the carbonization reaction and product quality, but also maximizes the utilization of resources and reduces the generation of waste.

[0030] Working principle: When using the medicinal baking soda production equipment, the purchased soda ash is first subjected to physical methods such as screening, crushing or magnetic separation to remove large impurities, foreign matter and dust attached to the surface. This step ensures the initial cleanliness of the raw materials and provides a good foundation for subsequent chemical reactions. Then, the baffle 15 is pulled and removed from the feed port 13 to open the feed port 13. Soda ash and condensed water are slowly and evenly added through the obliquely installed feed port 13. The oblique design helps to reduce the accumulation and blockage of materials during the feeding process, ensuring that the soda ash can smoothly fall into the alkali tank 5. Then, the first liquid pump 3 is started, and the first liquid pump 3 extracts the mother liquid in the mother liquid barrel 1 through the liquid infusion pipe 2, and then the mother liquid is pumped into the alkali tank 5 through the liquid outlet pipe 4. At the same time, the motor 7 is started, and the motor 7 drives the second pulley 11 and the second stirring rod 10 through the first pulley and the transmission belt 12. At this time, the first stirring rod 8 also rotates under the direct drive of the motor 7. The design of the double stirring rods can more effectively promote the mixing of soda ash, circulating mother liquid and condensed water, accelerate the reaction speed and improve the reaction uniformity. Subsequently, high-purity caustic soda (such as purity 99.9% flake caustic soda), as a strong base, can quickly react with NaHCO3 in the system to promote the conversion of NaHCO3 to Na2CO3. At the same time, the added sodium sulfide reacts with heavy metal ions such as iron and lead in the mother liquor to generate insoluble FeS and PbS precipitates, effectively removing these harmful impurities. The stirring system ensures that the reactants are fully mixed and improves the reaction efficiency. After the addition is completed, the operator reinserts the baffle 15 into the feed port 13 through the chute 14 to close the feed port 13 to prevent the escape of gas or splashes generated during the reaction. After the reaction is completed, the temperature in the alkali tank 5 is reduced to below 70°C to reduce the supersaturation of the solution and promote the precipitation of precipitates such as FeS and PbS. After standing for a period of time, gravity is used to allow the precipitate to fully settle to the bottom of the tank and separate from the supernatant. The cooled alkali solution is sent to the clarification tank 17, and suspended impurities and fine precipitates are further removed by natural sedimentation or the addition of a clarifier. Subsequently, the clarified liquid is filtered using precision filtration equipment such as a microporous PE filter to intercept tiny impurities The CO2 gas purified by the CO2 purification component 21 is introduced into the filtered alkali solution in the carbonation tower 18 for a carbonation reaction. By precisely controlling parameters such as reaction temperature, pressure, CO2 concentration, and composition, Na2CO3 reacts with CO2 to form sodium bicarbonate crystals. The CO2 gas used in the carbonation reaction is purified, typically using physical and chemical methods such as compression, condensation, and adsorption to remove impurities such as water vapor, dust, and sulfides. This ensures the purity and cleanliness of the CO2 gas and reduces its negative impact on the carbonization reaction and product quality. The sodium bicarbonate slurry removed from the bottom of the carbonization tower 18 is separated by a centrifugal washer 19, using centrifugal force to separate the crystals from the mother liquor. Subsequently, the crystals are centrifugally cleaned with deionized water to remove impurities and residual mother liquor from the crystal surface. The cleaned wet sodium bicarbonate product is then transferred to a drying oven 20 for hot air drying within a controlled temperature range (e.g., 130-140°C) to evaporate moisture from the crystals and improve the dryness and stability of the product.
