Description

Technical Field

[0001] This invention relates to the field of barium carbonate preparation technology, and in particular to a barium carbonate synthesis reactor and its application method. Background Technology

[0002] Barium carbonate has a wide range of industrial applications, primarily in the manufacture of electronic components. It can also be used to analyze the iron content in calcium, magnesium, manganese, and zinc, as well as to detect and determine halogens in organic compounds. Currently, the carbonation method is widely used in the preparation of barium carbonate. This involves passing carbon dioxide into a barium sulfide solution to induce a carbonation reaction, resulting in a barium carbonate slurry. Subsequent steps include desulfurization washing, vacuum filtration, drying, and pulverization to obtain the final barium carbonate product.

[0003] A utility model patent with authorization announcement number CN218530942U discloses a process apparatus for producing electronic-grade barium carbonate, relating to the field of chemical technology. The apparatus includes a barium hydroxide preparation tank and an atomizing tower. A high-pressure plunger pump is installed on the right side of the barium hydroxide preparation tank, and a flow guiding mechanism is provided above the high-pressure plunger pump. A carbon dioxide inlet pipe is installed on the outer surface of the atomizing tower. A 17.5% barium hydroxide solution is prepared and the temperature is controlled at 70 ℃, then pumped into the atomizing tower by the high-pressure plunger pump. The tower is filled with carbon dioxide gas. The barium hydroxide solution is sprayed into a mist from the top of the atomizing tower through a nozzle, instantly reacting with the carbon dioxide gas to produce barium carbonate. The solution flows out from the bottom of the tower for collection.

[0004] In the above technical solutions, barium hydroxide reacts with carbon dioxide to produce barium carbonate and water, while barium sulfate solution reacts with carbon dioxide to produce barium carbonate and hydrogen sulfide. Both solutions share a similarity: barium hydroxide and barium sulfide require contact with carbon dioxide gas to react. In existing solutions, carbon dioxide is directly introduced into the carbonation tower, and barium hydroxide is sprayed using nozzles. However, this structure is unsuitable for the process of preparing barium carbonate from barium sulfide. This is because the reaction of barium sulfide solution with carbon dioxide produces hydrogen sulfide, which needs to be discharged promptly. Existing solutions are not conducive to setting up a gas circulation structure, are unsuitable for handling hydrogen sulfide gas, and lead to a large waste of carbon dioxide, affecting production costs. Therefore, improvements are urgently needed. Summary of the Invention

The drive unit is located inside the sealed end of the exhaust pipe, and the movable end of the drive unit is connected to the first section; The other two ends of the exhaust pipe extend to the outside of the reaction pipe.

[0012] Based on the above technical solutions, preferably, the large-diameter section includes a connecting section and a submerged section, wherein, One end of the connecting section is detachably connected to the expanded diameter section; One end of the submerged section is detachably connected to the other end of the connecting section; The first guide plate is set on the inner wall of the connecting section; The exhaust pipe is fixed relative to the submerged section.

[0016] The barium carbonate synthesis reactor and its application method of the present invention have the following advantages over the prior art: (1) In this technical solution, a reaction tube and a guide tube are provided inside the tower. The reaction tube extends outside the tower to facilitate the input of carbon dioxide gas. The guide tube can guide the gas flow so that the carbon dioxide gas can fully react with the barium sulfide solution sprayed into the nozzle around the reaction tube, thus improving the utilization rate of raw materials.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1 like Figures 1-9 As shown, the barium carbonate synthesis reactor of the present invention includes a tower body 1, a reaction tube 2, a guide tube 3, and a nozzle 4.

[0021] like Figures 1-5As shown, the tower body 1, reaction tube 2, and guide tube 3 are coaxially arranged; the reaction tube 2 is located inside the tower body 1, and one end extends outside the tower body 1; the guide tube 3 is located inside the reaction tube 2, and the guide tube 3 and the reaction tube 2 form a turbulence section 100, which is used to reduce the gas flow rate and discharge the reaction gas; the nozzle 4 is arranged on the reaction tube 2, and the spray end of the nozzle 4 is located inside the reaction tube 2 and corresponds to the turbulence section 100; As described above, the tower body 1 serves as a reaction vessel, housing a reaction pipe 2, a guide pipe 3, and a nozzle 4. When in use, the tower body 1 is filled with barium sulfide solution, and the barium sulfide solution covers the lower end of the reaction tube 2. The reaction tube 2 extends to one end outside the tower body 1 and is used to connect to a carbon dioxide supply device to inject carbon dioxide gas into the reaction tube 2. After carbon dioxide gas is injected, it will be dispersed by the guide pipe 3. The carbon dioxide gas flows through the gap between the reaction pipe 2 and the guide pipe 3. At the same time, the barium sulfide solution is pumped into the nozzle 4 by the pump. The nozzle 4 sprays the barium sulfide solution to react with the flowing carbon dioxide gas to generate barium carbonate slurry. In this structure, a turbulence section 100 is formed between the reaction tube 2 and the guide tube 3 to reduce the flow rate of carbon dioxide gas and ensure that the carbon dioxide gas reacts fully with the barium sulfide solution. During the preparation process, the generated hydrogen sulfide gas is discharged through the guide pipe 3 to avoid occupying the volume of the reaction tube 2, thereby ensuring the normal progress of the reaction; since hydrogen sulfide gas is toxic, timely discharge of it also helps to ensure the safety of production.

[0022] like Figure 5 , Figure 8 and Figure 9 As shown, the reaction tube 2 includes a small-diameter section 21, an expanded-diameter section 22, a large-diameter section 23, and a first guide plate 24. The small-diameter section 21 is connected to the tower body 1 and extends to the outside of the tower body 1. One end of the expanded-diameter section 22 is connected to the small-diameter section 21. The large-diameter section 23 is connected to the other end of the expanded-diameter section 22. The first guide plate 24 is connected to the inner wall of the large-diameter section 23 and surrounds the flow guide tube 3 to form a turbulence section 100. As described above, the reaction tube 2 is divided into three parts from top to bottom: a small diameter section 21, an expanded diameter section 22, and a large diameter section 23. After carbon dioxide gas enters the small diameter section 21, it will be dispersed by the guide tube 3 and supplied downward through the periphery of the guide tube 3. Subsequently, the carbon dioxide gas flows through the expansion section 22 to the first guide plate 24, and a turbulence section 100 is formed above the first guide plate 24. At this time, the carbon dioxide gas reaches the large diameter section 23, thereby reducing the gas flow rate and achieving a gathering effect. Then, the barium sulfide solution sprayed by the nozzle 4 can fully react with the carbon dioxide gas, which is beneficial to ensuring the preparation effect of barium carbonate. Meanwhile, the smaller diameter of the small-diameter section 21 of the reaction tube 2 makes it easier to lead it outside the tower body 1 and connect it to the carbon dioxide gas supply equipment.

[0023] like Figures 5-7 As shown, the guide pipe 3 includes a guide section 31, a reduced diameter section 32, an extension section 33, and a second guide plate 34. The guide section 31 corresponds to the small diameter section 21; one end of the reduced diameter section 32 is connected to the guide section 31 and corresponds to the expanded diameter section 22; the extension section 33 is connected to the other end of the reduced diameter section 32 and corresponds to the large diameter section 23; the second guide plate 34 is connected to the reduced diameter section 32 and corresponds to the expanded diameter section 22; the nozzle 4 corresponds to the gap between the first guide plate 24 and the second guide plate 34. As described above, the guide pipe 3 is provided with a guide section 31, a narrowing section 32 and an extension section 33. The guide section 31 has a conical structure, which is beneficial for dispersing and guiding carbon dioxide gas and increasing the gas flow rate so that the carbon dioxide gas rushes toward the first guide plate 24, forming a vortex and accumulating in the turbulence section 100, which is beneficial for the reaction to proceed. Furthermore, the reduced diameter section 32 is provided with a second guide plate 34, which can work with the expanded diameter section 22 of the reaction tube 2 to guide the airflow and ensure that the carbon dioxide gas flows to the first guide plate 24. This structure allows carbon dioxide gas to fully contact the barium sulfide solution sprayed from the surrounding nozzles 4, and prevents the carbon dioxide gas from flowing directly downwards, thus facilitating contact and reaction with the barium sulfate solution.

[0024] like Figure 5 As shown, the guide pipe 3 also includes a filter plate 35 and an exhaust pipe 36. The filter plate 35 is sleeved on the extension section 33. One end of the filter plate 35 is connected to the second guide plate 34, and the other end is connected to the extension section 33. The reduced diameter section 32 has a through hole 301 corresponding to the filter plate 35. One end of the exhaust pipe 36 is connected to the extension section 33, and the other end extends to the outside of the tower body 1. As described above, the second guide plate 34 has an expanded structure, so the inner diameter reduction section 32 is convenient for opening through holes 301. When carbon dioxide gas mixes and reacts with barium sulfide solution in the turbulence section 100, hydrogen sulfide is formed and flows to the lower side of the second guide plate 34, then enters the guide pipe 3 through the through hole 301, and is then discharged through the exhaust pipe 36. This structure helps to ensure the normal progress of the reaction; at the same time, timely handling of hydrogen sulfide gas can ensure the safety of production. Specifically, a filter plate is installed between the second guide plate and the extension section for liquid filtration, thus preventing the discharge of spray mist through filtration. Specifically, the exhaust pipe 36 is connected to the induced draft device to achieve continuous discharge of hydrogen sulfide gas, or to work intermittently to achieve intermittent discharge of hydrogen sulfide gas.

[0025] like Figure 4 and Figure 5 As shown, the exhaust pipe 36 includes a three-way pipe 361 and a connecting pipe 362. One end of the three-way pipe 361 is connected to the extension section 33, and the other two ends extend to the outside of the reaction pipe 2. The three-way pipe 361 and the extension section 33 are detachably connected. Two connecting pipes 362 are provided. Each of the two connecting pipes 362 is connected to one port of the three-way pipe 361, and the other end of the connecting pipe 362 extends to the outside of the tower body 1. As described above, the exhaust pipe 36 is configured as two parts: a three-way pipe 361 and a connecting pipe 362. In this way, during assembly, most of the components of the guide pipe 3 are integrated with the reaction pipe 2 through the three-way pipe 361, and the connecting pipe 362 is inserted from the outside of the tower body 1. This can further ensure the integrity of the tower body 1, the reaction pipe 2 and the guide pipe 3, which is conducive to ensuring the stability of the overall structure and also facilitates integration. During the reaction, the hydrogen sulfide gas produced is discharged directly to the outside of the tower body 1 through the three-way pipe 361 and the connecting pipe 362.

[0026] like Figure 5 , Figure 7 and Figure 8 As shown, the large-diameter section 23 includes a connecting section 231 and a submerged section 232, wherein one end of the connecting section 231 is detachably connected to the enlarged-diameter section 22; one end of the submerged section 232 is detachably connected to the other end of the connecting section 231; a first guide plate 24 is disposed on the inner wall of the connecting section 231; and an exhaust pipe 36 is fixed relative to the submerged section 232. As described above, the large-diameter section 23 is divided into two parts: the connecting section 231 and the immersion section 232. It is designed to be detachable. Since the guide pipe 3 is integrated with the immersion section 232, most of the components of the guide pipe 3 will be exposed when the immersion section 232 and the connecting section 231 are separated. This facilitates cleaning and maintenance and improves the convenience of application. In practical applications, one end of the immersion section 232 is immersed in the barium sulfide solution to prevent the generated hydrogen sulfide gas from overflowing into the tower body 1, thereby avoiding residue problems.

[0027] like Figure 6 and Figure 7 As shown, the middle section of the reduced diameter section 32 is spaced to form a first chamber 302 that connects to the guide section 31 and a second chamber 303 that connects to the extension section 33; the first chamber 302 is a heating chamber; the second chamber 303 is connected to the exhaust pipe 36. As described above, the reduced diameter section 32 is configured as a hollow structure and as a spacer structure. When applied, the upper end of the guide tube 3, i.e. the first chamber 302, can accommodate a heating component to ensure the reaction temperature inside the reaction tube 2. The second chamber 303 is connected to the through hole 301 and the exhaust pipe 36, so that the reaction gas can be discharged outside the tower body 1.

[0028] like Figure 5 and Figure 9 As shown, the reaction tube 2 also includes a drain pipe 25. One end of the drain pipe 25 is connected to the first guide plate 24 and communicates with the upper space of the first guide plate 24; the other end of the drain pipe 25 is inclined toward the guide pipe 3. As described above, in order to form the turbulence section 100, the first guide plate 24 is set as an annular plate with an arc-shaped cross section. Therefore, in order to avoid the problem of liquid accumulation, a drain pipe 25 is opened so that the liquid accumulated on the first guide plate 24 can be discharged to avoid affecting the turbulence of carbon dioxide gas. Meanwhile, driven by the supply of carbon dioxide gas, since the other end of the drain pipe 25 is inclined toward the guide pipe 3, it can undergo a secondary reaction with the raw material flowing down between the first guide plate 24 and the guide pipe 3, which can improve the preparation efficiency of barium carbonate.

[0029] Example 2 like Figure 10 The difference between this embodiment and the first embodiment is that it also includes a driving component 5, and the exhaust pipe 36 is a four-way pipe; the extension section 33 includes a first section 331 that connects to the reduced diameter section 32, and a second section 332 that slides with the first section 331. One end of the exhaust pipe 36 is connected to the second section 332, and the other end is a sealed structure; the driving component 5 is set inside the sealed end of the exhaust pipe 36, and the movable end of the driving component 5 is connected to the first section 331; the other two ends of the exhaust pipe 36 extend to the outside of the reaction tube 2. As described above, in this embodiment, the exhaust pipe 36 has four ports, and the extension section 33 of the guide pipe 3 is configured as a sliding connection between the first section 331 and the second section 332; one port of the exhaust pipe 36 is connected to the second section 332, and the corresponding other port is set as a sealed structure for installing the drive member 5, and the movable end of the drive member 5 is connected to the first section 331. This structure allows the first section 331 and the portion of the guide tube 3 located on the upper side of the first section 331 to be lifted by the drive component 5 during the application of the reactor. In this way, the size of the turbulence section 100 can be adjusted according to the gas supply flow rate or the solution supply flow rate, thereby adjusting the gas retention time and improving the reaction effect.

[0030] like Figure 11 As shown, in a specific application, a pump is set up to extract the barium sulfide solution in the tower body 1 and supply it to the nozzle 4 through a pipeline to achieve a circulating reaction.

[0031] The application method of the barium carbonate synthesis reactor of the present invention includes the following steps: S1. Extend one end of the reaction tube 2 to the outside of the tower body 1 for the input of carbon dioxide gas; S2. Inject barium sulfide solution through nozzle 4; S3. When carbon dioxide gas flows to the turbulence section 100, it reacts fully with the barium sulfide solution sprayed by nozzle 4 to form barium carbonate slurry. S4. Connect the exhaust pipe 36 to the induced draft fan to draw out the hydrogen sulfide gas produced by the reaction.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
