Description

Technical Field

[0001] This application relates to the field of chemical equipment, and in particular to a reaction vessel for the production of water glass. Background Technology

[0002] Vertical reactors commonly used in water glass production often employ traditional paddle-type stirring structures. The solid-liquid mixture of silica sand and caustic soda solution is prone to stratification within the reactor. The solid raw materials at the bottom and walls of the reactor are difficult to stir sufficiently, leading to incomplete reaction. This not only reduces the yield of water glass products but also causes significant fluctuations in the product modulus due to differences in the degree of reaction in different areas, affecting quality stability. At the same time, the reaction temperature of atmospheric pressure reactors is limited by the boiling point of the solution, resulting in slow reaction rates, long cycles, and low production efficiency. Furthermore, the reactor body lacks a targeted solid-liquid separation structure, allowing unreacted silica sand residue to easily mix into the finished product, leading to a decrease in the transparency of the water glass and failing to meet the requirements of high-end applications.

[0003] High-pressure reactors are the core equipment for the production of high-modulus water glass. Existing equipment mostly uses flange-type sealing structures for the reactor body and lid. Under long-term high-temperature and high-pressure reaction conditions, the sealing gaskets are prone to aging and deformation, leading to leakage problems. This not only affects the continuity of production but also poses certain safety hazards. Furthermore, its heat exchange relies heavily on the external jacket structure, which has a limited heat exchange area and uneven temperature distribution of materials inside the reactor, making it difficult to accurately control reaction process parameters and easily causing inconsistent polymerization degrees of water glass. In addition, there is no anti-scaling design at the discharge port, and viscous water glass materials easily adhere to and form scale at the discharge port, frequently clogging the discharge channel. This is difficult to clean, and shutdown for cleaning will significantly reduce the continuous operating efficiency of the equipment.

[0004] However, in the process of implementing the technical solution, the inventors of this application discovered that the above-mentioned technology has at least the following technical problems: Existing equipment often uses flange-type sealing structures for the vessel body and lid. Under long-term high-temperature and high-pressure reaction conditions, the sealing gaskets are prone to aging and deformation, leading to leakage of liquid and gas. This not only affects the continuity of production but also poses certain safety hazards. Furthermore, its heat exchange relies heavily on the external jacket structure, which has a limited heat exchange area and uneven temperature distribution of materials inside the vessel, making it difficult to accurately control reaction process parameters and easily causing inconsistent polymerization degree of water glass. In addition, there is no anti-scaling design at the discharge port, and viscous water glass materials are prone to adhering and forming scale at the discharge port, frequently clogging the discharge channel. This makes cleaning difficult, and shutdown for cleaning will significantly reduce the continuous operating efficiency of the equipment. This solution addresses the issues of anti-sticking, anti-clogging, and precise control. Summary of the Invention

[0005] This application provides a reaction vessel for water glass production, solving the problems of existing high-pressure reaction vessels, which are the core equipment for high-modulus water glass production. Existing equipment often uses flange-type sealing structures for the vessel body and lid, which are prone to aging and deformation of the gaskets under long-term high-temperature and high-pressure reaction conditions, leading to leakage problems. This affects production continuity and poses certain safety hazards. Furthermore, heat exchange relies heavily on the external jacket structure, resulting in limited heat exchange area, uneven temperature distribution of materials inside the vessel, difficulty in accurately controlling reaction process parameters, and inconsistent polymerization degrees of water glass. In addition, the discharge port lacks anti-scaling design, allowing viscous water glass materials to easily adhere and form scale at the discharge port, frequently clogging the discharge channel, making cleaning difficult, and requiring shutdown for cleaning to significantly reduce the continuous operating efficiency of the equipment. This application achieves anti-sticking, anti-clogging, and precise control.

[0007] The dual-layer stirring system, which links the upper and lower parts, effectively solves the problems of solid-liquid stratification and incomplete local reaction in traditional reactors. The high-speed stirring blades in the upper processing tank can perform preliminary mixing and dispersion of silica sand and caustic soda solution, while the coaxially driven scraper blades and bottom plate blades in the lower reaction tank can achieve stirring throughout the entire reactor. In particular, the scraper blades can remove the material adhering to the reactor wall, and the bottom plate blades, together with the brush, can stir and clean the silica sand deposited at the bottom of the reactor, thereby significantly improving the uniformity of raw material mixing and reaction rate, reducing unreacted residue, and ensuring the stability of the modulus and the increase of yield of water glass products.

The high-speed stirring blades in the upper processing tank can perform preliminary mixing and dispersion of silica sand and caustic soda solution, while the coaxially driven wall scraper blades and bottom plate blades in the lower reaction tank can achieve stirring throughout the entire reactor. In particular, the wall scraper blades can remove the material adhering to the reactor wall, and the bottom plate blades, together with the brush, can stir and clean the silica sand deposited at the bottom of the reactor, thereby significantly improving the uniformity of raw material mixing and reaction rate, reducing unreacted residue, and ensuring the stability of the modulus and the increase of yield of water glass products.

[0017] 2. This reactor for water glass production achieves precise control of reaction temperature and efficient utilization of thermal energy through an integrated coil heat exchange and waste heat recovery system. The spiral coil is tightly fitted to the outer wall of the reaction tank, significantly increasing the heat exchange area. With the temperature and pressure sensor signals fed back to the controller, the flow rate of the heat exchange medium can be adjusted in real time to ensure uniform and stable temperature inside the reactor, which is beneficial for controlling the consistency of water glass polymerization. At the same time, the waste heat of steam generated in the treatment tank is introduced into the waste heat recovery block through heat conduction pipes, and after heat exchange through a serpentine flow channel, it is introduced into the coil for recycling. This not only saves energy and reduces consumption, but also improves the thermal management efficiency and process controllability of the entire reaction process. Attached Figure Description

[0024] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] This application discloses a reaction vessel for water glass production, including a body 1, a support column 2 fixedly installed at the bottom of the body 1, and an adjustment mechanism 3 provided inside the body 1; The regulating mechanism 3 includes a processing box 301. The processing box 301 is fixedly installed inside the machine body 1. An output shaft 302 is movably installed at the bottom inner part of the processing box 301. A high-speed stirring blade 303 is fixedly installed on the outer side of the output shaft 302. A pressure relief block 304 is fixedly installed on the top of the processing box 301. A sieve plate 305 is fixedly installed inside the pressure relief block 304. A conduit 306 is fixedly installed on the top of the processing box 301. A waste heat recovery block 307 is fixedly installed on the top of the processing box 301. A reaction box 308 located below the processing box 301 is fixedly installed inside the machine body 1. A feed pipe 309 penetrating into the processing box 301 is fixedly installed on the top inner part of the reaction box 308. A valve 310 is fixedly installed on the outer side of the feed pipe 309. A temperature sensor 311 is fixedly installed on the top inner part of the reaction box 308. A connecting bearing 312 is fixedly installed on the top inner part of the reaction box 308. A rotating shaft 313 is movably mounted on the inner side of the bearing 312. A scraper blade 314 is fixedly mounted on the outer side of the rotating shaft 313. A chassis 315 is fixedly mounted on the bottom of the reaction chamber 308. A chassis blade 316 adapted to the chassis 315 is fixedly mounted on the outer side of the rotating shaft 313. A brush 317 is fixedly mounted on the bottom of the chassis blade 316. A connecting block 318 is fixedly mounted on the bottom of the chassis 315. A quality detector 319 is fixedly mounted inside the connecting block 318. A valve plate 320 is movably mounted inside the connecting block 318. A threaded block 321 is fixedly mounted on the bottom of the connecting block 318. A discharge pipe 322 is movably mounted on the inner side of the threaded block 321. A pressure sensor 323 is fixedly mounted on the inner top of the reaction chamber 308. A coil 324 located outside the reaction chamber 308 is fixedly mounted inside the body 1. A connecting pipe 325 is fixedly mounted on the top of the coil 324.

[0026] In the implementation of the case, the bottom of the connecting block 318 is provided with a discharge port, the rotating shaft 313 and the output shaft 302 are connected by a coupling and driven by the same drive motor, and the surfaces of the rotating shaft 313 and the output shaft 302 are coated with a polytetrafluoroethylene anti-corrosion layer.

[0027] Among them, the polytetrafluoroethylene anti-corrosion layer can withstand the erosion of strong alkaline raw materials in water glass production, and avoid transmission jamming of the rotating shaft 313 and output shaft 302 due to corrosion. The discharge port at the bottom of the connecting block 318 can cooperate with the conical base and bottom brush of the reaction tank 308. During the discharge stage, the residual material at the bottom of the tank is discharged synchronously with the rotation of the stirring component, reducing the probability of material accumulation and blockage at the discharge port. Through the coupling connection between the rotating shaft 313 and the output shaft 302 and the coaxial drive design, the high-speed stirring blade 303, the wall scraping blade 314, and the chassis blade 316 can be operated synchronously to ensure that the materials in each area of ​​the vessel can be fully mixed. At the same time, the transmission structure, combined with the protection of the anti-corrosion layer, can improve the operational stability and durability of the drive system and reduce the frequency of daily maintenance of the equipment.

[0028] In the case implementation, the high-speed stirring blade 303 has a multi-layered inclined blade structure, and the blades of adjacent layers are inclined in opposite directions.

[0029] Among them, the multi-layer blade structure can broaden the spatial coverage of the stirring and act simultaneously on material areas at different heights in the reactor; while the design of the adjacent blade layers tilting in opposite directions can push the upper and lower layers of materials to form convective turbulence during rotation, solving the problem of stratification and accumulation of solid and liquid raw materials due to density differences, while enhancing the shear mixing strength between materials. The multi-layered reverse tilting structure design of the high-speed stirring blade 303 allows for more uniform contact and collision between sodium silicate raw material, water, and additives in water glass production, improving the degree of reaction. This reduces the residual loss of unreacted raw materials and helps stabilize the modulus and yield of the product. It also works synergistically with the wall scraper blade 314 and the chassis blade 316 to further optimize the material mixing effect of the entire reactor.

[0030] In the case implementation, an elastic scraper is provided at the end of the scraper blade 314, which contacts the inner wall of the reaction chamber 308.

[0031] Among them, the elastic scraper is made of alkali-resistant and wear-resistant fluororubber. Its elastic properties can not only closely fit the curvature of the inner wall of the reaction chamber, avoiding the hard scraper from scratching the anti-stick coating of the inner wall, but also adapt to the slight deformation of the inner wall, continuously scraping off the water glass adhering to the wall surface, preventing the adhering material from excessively polymerizing, scaling and hardening due to prolonged high temperature. By using the real-time contact scraping design between the elastic scraper at the end of the wall scraper blade 314 and the inner wall of the reaction chamber 308, the raw materials adhering to the wall can participate in the reaction again, improving the utilization rate of raw materials and the product yield. At the same time, it avoids the decrease in heat exchange efficiency caused by the accumulation of scale on the wall surface, and also reduces the frequency of equipment shutdown for disassembly and cleaning, further ensuring the continuous and stable operation of water glass production.

[0032] In the implementation of the case, the chassis 315 is a conical structure with a downward protrusion, and its surface is provided with an anti-stick coating; the brush 317 is attached to the conical surface of the chassis 315.

[0033] The downward-convex conical structure can guide the material towards the discharge port by gravity, avoiding the material from staying in the chassis area for a long time; the anti-stick coating on its surface is made of polytetrafluoroethylene material that is the same as that of the rotating shaft, which can greatly reduce the adhesion of water glass material; and the brush 317 is made of alkali-resistant and wear-resistant nylon filament material. Its design that fits the conical surface can rotate synchronously with the stirring component to clean the residual sticky material in the chassis 315 in real time, preventing the material from hardening and scaling in the chassis 315. The conical structure of the chassis 315, the anti-stick coating, and the close fit design of the brush 317 not only allow the reacted materials to be more smoothly concentrated at the discharge port, reducing the probability of discharge blockage, but also allow the residual materials in the chassis 315 to be re-mixed into the reaction system, further improving the fullness of the raw material reaction, while also reducing the workload of subsequent equipment cleaning.

[0034] In the implementation of the case, the waste heat recovery block 307 is equipped with a serpentine heat exchange channel inside. The inlet of the heat exchange channel is connected to the top of the processing box 301, and the outlet is connected to the top of the coil 324.

[0035] The meandering layout of the serpentine heat exchange channel can significantly increase the contact area and time of heat exchange, thereby improving the efficiency of waste heat recovery. The connection with the top of the treatment box 301 is to collect the waste heat carried by the high-temperature steam generated during the reaction process. The connection between the outlet and the top of the coil 324 can transfer the recovered heat to the heat exchange medium in the coil, thereby realizing the directional reuse of waste heat. By connecting the serpentine flow channel of the waste heat recovery block 307 with the coil 324, the waste heat of the steam that would otherwise be lost can be reintroduced into the heat exchange stage of the reaction system, reducing the energy consumption of external heat sources and achieving energy-saving effects. At the same time, it can also help stabilize the initial temperature of the heat exchange medium in the coil 324, making the temperature regulation of the reaction chamber 308 more precise and efficient, and further ensuring the stability of the water glass production process parameters.

[0036] In the implementation of the case, temperature sensor 311, pressure sensor 323, and mass detector 319 are all electrically connected to the controller; valve 310 is an electrically controlled valve and is electrically connected to the controller.

[0037] Among them, the temperature sensor 311 can collect the reaction temperature data in the reaction tank in real time and transmit it to the controller, providing a precise basis for the controller to adjust the flow rate of the heat exchange medium; the pressure sensor 323 can synchronously feed back the pressure value in the vessel to prevent the reaction pressure from exceeding the safety threshold; the quality detector 319 can monitor the quality parameters of the discharged water glass product, such as modulus and concentration, in real time to assist the controller in judging the reaction process; the electric control valve 310 receives the instructions from the controller and automatically adjusts the raw material feed rate, the on / off state of the heat exchange medium, etc., to realize the automated control of the process. By designing a coordinated electrical connection between temperature sensor 311, pressure sensor 323, quality detector 319, and electric control valve, an automated monitoring and control closed loop for water glass production is constructed. This not only replaces the traditional manual detection and adjustment methods, improving the control accuracy of process parameters such as temperature and pressure, but also allows for timely adjustments to the production process through real-time product quality detection, ensuring the stability of product indicators, while also reducing errors and safety risks associated with manual operation.

[0038] In the case implementation, coil 324 is tightly wound in a spiral shape around the outer wall of reaction chamber 308.

[0039] The spiral layout maximizes the coverage of the outer wall area of ​​the reaction chamber 308, allowing for more thorough heat exchange between the heat exchange medium and the reaction chamber 308. The "tightly wrapped" design reduces heat loss during the heat exchange process, improves energy utilization efficiency, and covers different height areas of the reaction chamber 308, preventing local temperatures from being too high or too low and ensuring the uniformity of the reaction environment. By tightly winding the outer wall of the reaction chamber 308 with a spiral coil 324, the temperature regulation inside the reaction chamber 308 can be more efficient and uniform. This not only helps to stabilize the process temperature required for water glass production and improve the consistency of the reaction and the stability of product quality, but also, in conjunction with the heat supply of the waste heat recovery system, further reduces the energy consumption input of external heat sources, achieving the dual benefits of energy saving and process stability.

[0040] In the case implementation, the processing box 301 and the reaction box 308 are arranged coaxially, and the feed pipe 309 is arranged in the vertical direction.

[0041] The coaxial layout allows for a more regular material transfer path between the processing tank 301 and the reaction tank 308, preventing material from shifting or remaining during cross-tank transport. The coaxial structure also ensures more balanced stress distribution on the equipment, improving structural stability during operation. The vertical guide pipe 309 uses gravity to assist the viscous water glass raw material in falling, reducing material adhesion and accumulation on the inner wall of the guide pipe 309 and ensuring smooth feeding. By setting the processing tank 301 and the reaction tank 308 coaxially and using the vertical guide pipe 309, the efficiency of material transfer across the tanks is improved, the residual loss of raw materials is reduced, the overall structure of the equipment is more compact, the production space is saved, and the corresponding assembly and subsequent maintenance of functional components such as stirring and heat exchange are facilitated, thus improving the integrated practicality of the equipment.

[0042] When implementing this procedure, please follow these steps: 1) First, add silica sand and caustic soda solution to the treatment tank 301, start the drive motor, and perform preliminary mixing through the high-speed stirring blade 303. Then, open the valve 310 to allow the material to enter the reaction tank 308 through the feed pipe 309. 2) Then start the heat exchange medium circulation of coil 324 and start the waste heat recovery system; the controller automatically adjusts the process parameters based on the feedback from temperature sensor 311 and pressure sensor 323. 3) During the reaction process, the coaxially driven scraper blades 314 and chassis blades 316 operate continuously to achieve uniform stirring and cleaning of the entire vessel and the bottom of the vessel. 4) Finally, when the quality detector 319 shows that the reaction has reached the required level, the valve plate 320 is opened and the material is discharged through the discharge pipe 322; the brush 317 rotates with the chassis blade 316 to clean the residue on the chassis 315.
