DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] like Figure 1 and Figure 2 As shown, an energy-saving and efficient wet-process sodium carbonate reactor comprises a reactor body 1, a reactor cover 2 is arranged at the upper end of the reactor body 1, a stirring rod 4 is arranged in the middle of the reactor cover 2, a motor 3 is connected to the upper end of the stirring rod 4, a graphite pressure ring 7 is arranged on the stirring rod 4 located above the reactor cover 2, a first blade 41, a second blade 42 and a third blade 43 are arranged in sequence on the stirring rod 4 located inside the reactor body 1, a sodium carbonate pipeline 5 is fixed on one side of the inner wall of the reactor body 1, and a steam pipeline 6 is fixed on the side of the inner wall of the reactor body 1 opposite to the sodium carbonate pipeline 5; by optimizing the structure and operation process, the production efficiency is improved and the energy consumption is reduced; the reactor body 1 is used as a container for the entire reaction process, and the reactor body 1 (usually also called a reactor or reactor) needs to be able to withstand the pressure, temperature and chemical corrosion that may be generated during the reaction process. Its design should ensure good sealing and stability to maintain the stability of the reaction environment; the reactor cover 2 is located at the upper end of the reactor body 1, and is used to close the reaction space to prevent the reactants from leaking. The kettle cover 2 is usually provided with various interfaces, such as a channel for the stirring rod 4, an observation window, a sampling port, etc., to facilitate operation and monitoring of the reaction process; the stirring rod 4 is driven by the motor 3 and rotates in the reactor to stir the reactants, promote uniform mixing of the materials and increase the reaction rate. The design of the stirring rod 4 (such as length, diameter, blade shape and number) will directly affect the stirring effect and energy consumption; the graphite pressure ring 7 is located at the upper end of the stirring rod 4, connected to the kettle cover 2 or the motor 3. The graphite material has good high temperature resistance and corrosion resistance, which can effectively protect the connection between the stirring rod 4 and the motor 3 from the influence of the reaction medium, while reducing friction and wear, and improving the service life of the equipment; the first blade 41, the second blade 42 and the third blade 43, these blades are installed on the stirring rod 4 in a certain order and angle, and they each play a different role in the stirring process. For example, the first blade 41 may be mainly responsible for lifting the reactants from the bottom to the top to form a preliminary mixture; the second blade 42 may focus on diffusing the material in the horizontal direction; the third blade 43 may further refine the mixing to ensure sufficient contact between the reactants. Through the synergistic effect of multiple layers of blades, the reaction efficiency and uniformity can be significantly improved; the sodium carbonate pipeline 5 is fixed on one side of the inner wall of the kettle body 1, and is used to inject sodium carbonate or other reaction raw materials into the reactor. The design of the pipeline should ensure that the raw materials can enter the reaction area accurately and evenly to avoid uneven reactions caused by excessive or low local concentrations; the steam pipeline 6 is fixed on the inner wall of the kettle body 1 on the side opposite to the sodium carbonate pipeline 5, and is used to pass steam into the reactor. The addition of steam can heat the reactants and increase the reaction rate, and it also helps to control the reaction temperature and ensure the stability and safety of the reaction process. The design of the steam pipeline 6 should take into account factors such as thermal efficiency, temperature uniformity and safety.
[0023] like Figure 1As shown, a sodium carbonate feed port 51 is provided at one end of the sodium carbonate pipeline 5, and the sodium carbonate feed port 51 extends out of the upper end of the kettle cover 2, and a sodium carbonate discharge port 52 is provided at the other end of the sodium carbonate pipeline 5, and the sodium carbonate discharge port 52 is bent and fixed at the bottom end of the kettle body 1; the sodium carbonate pipeline 5 provided on one side of the inner wall of the kettle body 1 introduces raw materials into the kettle body 1 through the sodium carbonate feed port 51, and discharges the waste materials after the reaction from the kettle body 1 as much as possible through the sodium carbonate discharge port 52. This design makes the addition of raw materials and the discharge of products more convenient and efficient; the sodium carbonate discharge port 52 is bent and fixed at the bottom end of the kettle body 1: this design helps to reduce material residues and improve the recovery rate of products.
[0024] like Figure 1 As shown, a steam inlet 61 is provided at one end of the steam pipe 6, and the steam inlet 61 extends out of the upper end of the kettle cover 2; the steam pipe 6 introduces steam through the steam inlet 61 to provide a heat source for the material in the kettle body 1 and promote the reaction of sodium carbonate. Steam, as a clean energy source, has the advantages of high heating efficiency and environmental protection and no pollution.
[0025] like Figure 1 As shown, a steam muffler 62 is provided at the other end of the steam pipe 6, and the steam muffler 62 is parallel to the inner wall of the kettle body 1; during the steam pressurization process, strong noise and vibration will be generated when mixing with the finished product. A steam muffler 62 is provided at the other end of the steam pipe 6 to reduce noise pollution during steam discharge and improve the comfort of the production environment.
[0026] like Figure 1 As shown, the kettle wall of the kettle body 1 is provided with a kettle body lining structure 8; since the quartz sand causes great wear to the kettle body during the stirring process, in order to facilitate the subsequent maintenance, a set of kettle body lining structural design is added, which greatly prolongs the service life of the reactor.
[0027] like Figure 1 As shown, the graphite pressure ring 7 is sealed with a packing; the frame and the kettle body adopt a graphite pressure ring 7 and a packing seal design. Compared with the mechanical seal, the packing seal has a simple structure, low price, and convenient maintenance, and is more suitable for high-temperature steam and low-speed working conditions.
[0028] like Figure 2 As shown, a steam circulation port 9 is provided on the kettle cover 2; a set of steam circulation ports 9 is added to the kettle cover 2 to discharge excess steam into other kettles to preheat the next batch of materials.
[0029] Working principle: Sodium carbonate enters the sodium carbonate pipeline 5 through the sodium carbonate feed port 51 arranged at the upper end of the kettle body 1. After entering the pipeline, the sodium carbonate flows into the kettle body 1 through the pipeline; the motor 3 drives the stirring rod 4 to rotate, and the first blade 41, the second blade 42 and the third blade 43 on the stirring rod 4 mix and stir the sodium carbonate in the kettle body 1 in turn. This multi-layer blade design helps to achieve a more uniform mixing effect and improve the reaction efficiency; the graphite pressure ring 7 and the packing seal arranged at the upper end of the stirring rod 4 ensure the sealing of the stirring system and prevent material leakage; the steam enters the kettle body 1 through the steam pipeline 6 to heat the sodium carbonate. A steam inlet 61 is provided at one end of the steam pipeline 6, which is connected to an external steam source. Steam exchanges heat with sodium carbonate in the kettle body 1 to promote chemical reactions or physical changes of sodium carbonate. The steam muffler 62 provided at the other end of the steam pipe 6 is used to reduce noise during steam discharge and also helps to discharge steam smoothly. The design of the kettle body 1 may include a kettle body lining structure 8, which may be used to enhance heat transfer efficiency and improve energy utilization. The steam circulation port 9 provided on the kettle cover 2 may be used for steam recycling or emission control to further improve the energy efficiency of the system. After sufficient mixing and heating reaction, sodium carbonate is discharged through the sodium carbonate discharge port 52 at the other end of the sodium carbonate pipe 5. The sodium carbonate discharge port 52 is bent and fixed at the bottom of the kettle body 1 to help completely discharge the reaction product.
[0030] In summary, the energy-saving and high-efficiency wet-process sodium carbonate reactor adopts a graphite pressure ring 7 and a packing seal design for the frame and the reactor body. Compared with mechanical seals, the packing seal has a simple structure, is cheap, and is easy to maintain, and is more suitable for high-temperature steam and low-speed working conditions; a three-layer high-efficiency and wear-resistant blade is designed to increase the service life of the blade, while enhancing the stirring efficiency in the reactor and shortening the reaction time; a special inlet and outlet pipe design is adopted to allow the waste produced to be discharged from the reactor body as much as possible; a wear-resistant muffler is designed at the end to reduce the strong noise and vibration generated when mixing with the finished product during the steam pressurization process; a set of steam circulation ports 9 is added in the process to discharge excess steam into other reactors to preheat the next material; since the quartz sand wears the reactor body more during the stirring process, in order to facilitate later maintenance, a set of structural design for the inner lining of the reactor body is added, which greatly prolongs the service life of the reactor.
