Description

Technical Field

[0001] This invention relates to the field of mechanical equipment technology, specifically to a gas-liquid atomizing swirling mixing reaction device. Background Technology

[0002] In modern industrial production, mixing reactors are widely used in many fields such as chemical engineering, pharmaceuticals, environmental protection, and food processing. The mixing and reaction of different fluid materials includes processes such as the synthesis, precipitation, crystallization, and extraction of different chemical raw materials. Mixing and reaction devices mainly include types such as kettles, tanks, towers, and tubular reactors. Kettles and tanks mostly employ a bottom liquid in the mixing reactor, with the two materials added from different inlets, and then directly mixed and reacted within the reactor through mechanical stirring. Towers and tubular reactors mostly have irregularly shaped structural components or fillers installed inside, allowing different liquid materials to be mixed through forced convection and diffusion during flow. The common feature of both is that pure liquid materials are mixed to achieve chemical reactions between different materials, leading to processes such as synthesis, precipitation, and crystallization.

[0003] In existing technologies, traditional mixing reaction devices (batch reactors and continuous reaction devices) mostly rely on mechanical stirring or forced turbulence to achieve fluid mixing reactions. This mainly presents three problems: First, high-concentration, high-viscosity liquids require long mixing times, resulting in poor dispersibility and uniformity. Local material ratios deviate from theoretical values, easily generating non-target products and affecting product quality. Second, backmixing and short-circuiting are prone to occur in large-capacity containers, leading to significant differences in material residence time, resulting in wide particle size distribution and mutual entanglement of precipitated crystals. Simultaneously, some materials do not react fully, reducing raw material yield and production efficiency. Third, a large amount of liquid needs to be retained in the container, and the process of uniformly mixing new materials is slow. When using pH, conductivity, and temperature as control indicators, the sensitivity is low and the lag is large, making it difficult to automatically and accurately control the feed flow rate and ratio. Summary of the Invention

[0004] The purpose of this invention is to provide a gas-liquid atomizing swirling mixing reaction device to solve the problems of slow mixing, poor uniformity, and local material imbalance in traditional mixing reaction devices that rely on mechanical stirring or forced turbulent mixing as described in the background art; back mixing and short circuits are prone to occur in the container, resulting in inconsistent crystallization quality, incomplete reaction, and low yield; and the feedback of parameters such as pH and temperature is lagging, resulting in poor automatic control accuracy.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-16This invention provides an embodiment of a gas-liquid atomizing swirling mixing reaction device, comprising a mounting bracket 1, a disc-shaped mixing reaction chamber 21 detachably mounted on the mounting bracket 1 by bolts, a connecting chamber 22 detachably mounted on the top of the mixing reaction chamber 21 by bolts, a gas-liquid separation chamber 23 detachably mounted on the top of the connecting chamber 22 by bolts, a gas-liquid separation mesh 29 fixedly connected inside the gas-liquid separation chamber 23, an atomizing nozzle 24 fixedly connected to the mixing reaction chamber 21, a pressure regulating unit mounted on the atomizing nozzle 24, a drive unit and an indicator unit mounted on the pressure regulating unit, a gas feed pipe 25 fixedly connected at one end to the atomizing nozzle 24, and a gas feed pipe 25 fixedly connected at one end to the atomizing nozzle 24. The liquid feed pipe 26 on the 4th floor, the overflow pipe 27 which is detachably bolted to the mixing reaction chamber 21, the material channel hole 28 which is opened between the connecting chamber 22 and the overflow pipe 27, the connecting pipe 210 which is detachably bolted to the top of the gas-liquid separation chamber 23, the exhaust valve 211 which is fixedly connected to the top of the connecting pipe 210, the exhaust pipe 212 which is fixedly connected to the output end of the exhaust valve 211 at one end, the long pipe 213 which is fixedly connected to the position of the overflow pipe 27 in the mixing reaction chamber 21, the discharge pipe 214 and the self-control probe mounting pipe 216 which are fixedly connected to the long pipe 213 from top to bottom, and the discharge valve sealing plate 215 which is detachably bolted to the bottom of the long pipe 213, and the discharge pipe 214 is used to connect external pipes or subsequent reactors via flanges; exhaust pipe 212 is used to discharge gas; gas-liquid separation screen 29 is used to separate gas and liquid; discharge valve sealing disc 215 discharges residual liquid through its own discharge valve; mounting bracket 1 provides a stable support foundation for the entire device; mixing reaction chamber 21, connecting chamber 22, and gas-liquid separation chamber 23 are bolt-mounted for easy assembly, disassembly, transportation, and internal cleaning and maintenance; atomizing nozzle 24, in conjunction with gas feed pipe 25 and liquid feed pipe 26, can fully atomize liquid materials and gas into tiny droplets, significantly improving material dispersion and mixing efficiency; overflow pipe 27, in conjunction with material channel hole 28, achieves orderly material flow and stable liquid level. The control system, with connecting pipe 210, exhaust valve 211, and exhaust pipe 212 working together to ensure orderly gas discharge and stable internal pressure, enables stable output of reactants and convenient connection to subsequent process equipment. The self-control probe mounting pipe 216 provides an installation position for online detection probes, enabling real-time monitoring and precise control of gas-liquid feed parameters. The exhaust valve sealing disc 215 facilitates rapid emptying of internal residual liquid during equipment maintenance and shutdown, preventing material residue contamination and corrosion. The gas-liquid separation mesh 29 achieves efficient gas-liquid separation, ensuring the purity of the discharged liquid phase and the cleanliness of the exhaust. The overall structure is reasonably laid out and highly integrated, meeting the process requirements of continuous atomization, swirling mixing, and reaction of multiple materials.

[0020] Please see Figure 1-14A further solution based on this embodiment is as follows: a first sealing ring is provided between the mixing reaction chamber 21 and the connecting chamber 22; a second sealing ring is provided between the connecting chamber 22 and the gas-liquid separation chamber 23; a third sealing ring is provided between the overflow pipe 27 and the mixing reaction chamber 21; a fourth sealing ring is provided between the gas-liquid separation chamber 23 and the connecting pipe 210; and a fifth sealing ring is provided between the long pipe 213 and the discharge valve sealing plate 215. By providing a first sealing ring between the mixing reaction chamber 21 and the connecting chamber 22, leakage from the joint surface of the gas-liquid mixture can be effectively prevented during the swirling mixing reaction, ensuring the airtightness and pressure stability of the mixing reaction space. By providing a second sealing ring between the connecting chamber 22 and the gas-liquid separation chamber 23, leakage of the gas-liquid two-phase fluid during the rising phase can be prevented. To prevent leakage during the separation process and ensure a reliable and sealed gas-liquid separation environment, a third sealing ring is installed between the overflow pipe 27 and the mixing reaction chamber 21 to prevent liquid material from leaking through the installation gap of the overflow pipe 27, ensuring smooth and leak-free overflow. A fourth sealing ring is installed between the gas-liquid separation chamber 23 and the connecting pipe 210 to prevent gas leakage from the connection point after separation, ensuring a sealed and controllable exhaust path. A fifth sealing ring is installed between the long pipe 213 and the discharge valve sealing plate 215 to prevent material leakage from the bottom discharge end during normal operation of the device, while ensuring sealing reliability during maintenance discharge. The synergistic effect of multiple sealing structures comprehensively improves the overall sealing performance of the device, avoids material loss, environmental pollution and safety hazards, and ensures stable and continuous operation of the reaction system.

[0021] Please see Figure 10-11 A further solution based on this embodiment is as follows: the gas-liquid separation screen 29 is set in a cone shape that is wider at the top and narrower at the bottom. By setting the gas-liquid separation screen 29 in a cone shape that is wider at the top and narrower at the bottom, the contact area between the gas and liquid phase fluids and the screen can be increased, the residence time of the fluid in the separation area can be extended, and the liquid phase droplets can be more fully collided, coalesced, and flow back downward under the action of gravity, which significantly improves the gas-liquid separation efficiency and separation effect. The cone structure gradually shrinks from top to bottom, which can guide and stabilize the rising airflow, avoid the liquid phase entrainment caused by airflow turbulence, and facilitate the smooth sliding of the coalesced liquid phase material to the overflow pipe 27 area, reduce the phenomenon of material adhesion to the wall, keep the screen unobstructed and the separation performance stable, and the cone structure is uniformly stressed, which can withstand the impact of airflow and the scouring of materials, and improve the operating stability and service life of the device.

[0022] Please see Figure 7 and Figure 13-14A further solution based on this embodiment is as follows: several groups of atomizing nozzles 24 are provided, and these groups of atomizing nozzles 24 are evenly distributed in a ring on the mixing reaction chamber 21. By providing several groups of atomizing nozzles 24 evenly distributed in a ring on the mixing reaction chamber 21, multiple liquid materials and gases can be simultaneously atomized and fed, so that each material enters the mixing reaction space in the form of tiny droplets, avoiding excessively high or low local material concentrations, and greatly improving the uniformity of material mixing and reaction synchronization. The evenly distributed ring layout can ensure that the atomized jet enters the mixing reaction chamber 21 tangentially, forming a stable and orderly swirling field, strengthening the collision, diffusion and mixing between materials, reducing backmixing and short-circuiting phenomena. At the same time, the number and layout of atomizing nozzles 24 can be flexibly adjusted according to process requirements to adapt to the mixing reaction of two or more liquid materials, improve the versatility and process adaptability of the device, and meet the needs of efficient mixing reaction of multiple materials in different production scenarios.

[0023] Please see Figure 15-16 A further embodiment of this solution is as follows: The pressure regulating unit includes a light rod 31 rotatably connected to the atomizing nozzle 24, a pressure regulating plate 34 fixedly connected to the light rod 31, a sealing sleeve 35 fixedly connected to the pressure regulating plate 34, a stepped plate 32 fixedly connected to the light rod 31, and a sealing gasket 33 fixedly connected to the atomizing nozzle 24 at the corresponding step plate 32. The sealing sleeve 35 contacts the inner wall of the atomizing nozzle 24, the stepped plate 32 is rotatably connected to the atomizing nozzle 24, and the stepped plate 32 contacts the sealing gasket 33. By driving the pressure regulating plate 34 and the sealing sleeve 35 to rotate through the light rod 31, the internal air pressure of the atomizing nozzle 24 can be precisely adjusted. The opening of the liquid flow channel allows for flexible control of the gas and liquid feed flow rate and injection pressure, ensuring stable and uniform material atomization. The stepped plate 32 and the sealing gasket 33 work together to form a reliable seal during adjustment, preventing gas and liquid materials from leaking from the adjustment part. The sealing sleeve 35 is in close contact with the inner wall of the atomizing nozzle 24, further improving the sealing performance and adjustment accuracy, ensuring that a stable and suitable atomized jet can be formed under different working conditions. This pressure regulating unit has a compact structure and sensitive adjustment, which can effectively ensure the stability of material atomization particle size, injection angle and feed rate, providing a stable and reliable material basis for subsequent swirling mixing and reaction.

[0024] Please see Figure 16A further solution based on this embodiment is as follows: both the stepped plate 32 and the sealing gasket 33 are set in a stepped shape, and an annular groove is opened on the atomizing nozzle 24. The stepped plate 32 is rotatably connected to the annular groove where the sealing gasket 33 is fixed. By setting the stepped plate 32 and the sealing gasket 33 in a stepped shape and cooperating with the annular groove installation structure on the atomizing nozzle 24, the contact area between the stepped plate 32 and the sealing gasket 33 can be increased, forming a multi-layer sealing surface, significantly improving the sealing reliability and pressure bearing capacity, effectively preventing high-pressure gas and liquid materials from leaking from the adjustment gap. The stepped structure can accurately position and guide the stepped plate 32, ensuring that the rotation adjustment process of the light rod 31 is smooth and stable, without jamming or offset, ensuring the pressure adjustment accuracy and operational stability. The annular groove provides a stable installation space for the stepped plate 32 and the sealing gasket 33, making the overall structure compact and reasonable, ensuring the sealing effect without affecting the normal realization of the pressure adjustment function, extending the service life of the pressure adjustment unit, and improving the long-term operational stability of the device.

[0025] Please see Figure 16 A further solution based on this embodiment is as follows: The drive unit includes a worm 37 rotatably connected to the atomizing nozzle 24, a micro motor 36 fixedly connected to the atomizing nozzle 24, a worm wheel 38 fixedly connected to one end of the optical rod 31, and two sets of limiting blocks 39 fixedly connected to the worm wheel 38. The worm 37 is fixedly connected to the output end of the micro motor 36, and the worm wheel 38 meshes with the worm 37. The two sets of limiting blocks 39 are used to limit the rotation of the optical rod 31 by ±90°. By driving the worm 37 through the micro motor 36, the worm wheel 38 is rotated, thereby realizing the automated and precise drive of the optical rod 31, and thus completing the automatic adjustment of the pressure regulating unit without the need for... Manual operation enhances the automation level and adjustment precision of the device, ensuring timely and accurate control of gas-liquid feed parameters. The worm gear 38 and worm 37 transmission have self-locking performance, maintaining the stable position of the pressure regulating plate 34 after adjustment, preventing changes in opening due to material pressure fluctuations, and ensuring constant atomization and mixing states. Two sets of limit blocks 39 restrict the rotation range of the guide rod 31 to ±90°, which can meet the flow and pressure adjustment requirements, while preventing excessive rotation from damaging the internal sealing structure and adjustment components, protecting the safe and stable operation of the device. This drive unit responds quickly and controls precisely, and can be adapted to online automatic control systems to achieve real-time closed-loop adjustment of process parameters.

[0026] Please see Figure 15-16A further solution based on this embodiment is as follows: The indicating unit includes a pointer 41 fixedly connected to the light rod 31 at one end and several sets of scales 42 opened at the corresponding light rod 31 on the atomizing nozzle 24. By cooperating with the scales 42 on the atomizing nozzle 24, the adjustment position and opening size of the pressure regulating unit can be displayed intuitively and accurately. This facilitates the operator to observe, record and calibrate the gas-liquid feed adjustment parameters in real time, ensuring the consistency and repeatability of production process parameters under different batches and different working conditions. The scales 42 are clearly marked and easy to read, enabling precise fine-tuning and avoiding errors caused by adjustment based on experience. This improves the stability and controllability of the atomization effect and the mixing reaction process. At the same time, it provides intuitive position feedback for the automated control system, facilitating parameter calibration and fault diagnosis, and improving the ease of operation and process control accuracy of the device.

[0027] Working Principle: During operation, the mounting bracket 1 first provides stable support for the entire device, ensuring stability during operation. Then, the gas feed pipe 25 and liquid feed pipe 26 respectively supply gas and liquid materials to several groups of evenly distributed atomizing nozzles 24 in a ring. The micro motor 36 in the drive unit starts, driving the worm gear 37 to rotate. The worm gear 37 meshes with the worm wheel 38, which in turn drives the guide rod 31 to rotate. During the rotation of the guide rod 31, two sets of limit blocks 39 limit its rotation by ±90° to prevent excessive rotation and damage to components. Simultaneously, the pointer 41 in the indicating unit rotates synchronously with the guide rod 31, and in conjunction with the scale 42 on the atomizing nozzles 24, provides a clear visual indication. The adjustment position and opening of the pressure regulating unit are displayed, allowing operators to accurately control the adjustment parameters. The rotation of the guide rod 31 drives the pressure regulating disc 34 and the sealing sleeve 35 in the pressure regulating unit to rotate synchronously, precisely adjusting the opening of the gas-liquid flow channel inside the atomizing nozzle 24. This enables flexible control of the gas-liquid feed flow rate and injection pressure. The stepped disc 32 and the stepped sealing gasket 33 fit tightly in the annular groove, forming a reliable seal. The sealing sleeve 35 is in close contact with the inner wall of the atomizing nozzle 24, further improving the sealing performance and preventing gas-liquid material leakage. This ensures a stable and suitable atomized jet under different operating conditions, allowing liquid materials and gas to be fully atomized into tiny droplets. Furthermore, the mixing reaction chamber 21 contains its own... The atomization chamber provides a dedicated buffer and atomization enhancement space for the atomized fluid, allowing the gas-liquid mixture ejected from the atomizing nozzle 24 to undergo secondary atomization and flow field stabilization within the atomization chamber before entering the mixing reaction chamber 21. This ensures thorough mixing of the gas and liquid phases and that the liquid is dispersed into uniform micro-droplets, effectively preventing uneven mixing caused by insufficiently atomized materials entering the mixing reaction chamber 21. This lays a good foundation for subsequent swirling mixing reactions. Two or more atomized fluids, after thorough atomization, enter the disc-shaped mixing reaction chamber 21 from different positions along the same tangential direction through the nozzle. The precise structural design of the nozzle provides directional guidance for the fluid flow, effectively preventing fluid stagnation. To address issues of turbulence and flow deviation, the system ensures that each atomized fluid stream enters the mixing reaction chamber 21 and forms a stable, unidirectional rotating flow. The fluid's own swirling motion achieves self-stirring, eliminating the need for additional mechanical stirring structures. This allows different atomized fluids to fully collide, diffuse, and mix during the swirling process, significantly improving mixing uniformity and reaction efficiency. Simultaneously, it reduces backmixing and short-circuiting, ensuring consistent material residence time. Furthermore, the disc-shaped mixing reaction chamber 21 adapts to the swirling motion of the atomized fluids, forming a stable and orderly flow field, preventing flow obstruction and turbulence. It also shortens the radial flow distance of the material, preventing localized accumulation and allowing multiple atomized materials to quickly and fully collide and achieve uniform mixing throughout the entire process.It can also precisely correspond to the layout of the overflow pipe 27 and the material channel hole 28, so that the mixed material flows in an orderly manner. With the help of the annular atomizing nozzle 24, it can achieve precise matching between the feed and the flow field, which greatly improves the overall uniformity of mixing and thus realizes the self-stirring function. It eliminates the need for traditional mechanical stirring mechanisms, effectively improves the uniformity of material mixing and reaction rate, and reduces backmixing and short-circuiting. During the mixing reaction, the gas and liquid two-phase fluids flow upward through the connecting chamber 22 into the gas-liquid separation chamber 23. The connecting chamber 22 can not only achieve smooth communication between the mixing reaction chamber 21 and the gas-liquid separation chamber 23, but also ensure the smooth flow of gas and liquid. The orderly flow of the mixed fluid from the mixing reaction chamber 21 to the gas-liquid separation chamber 23 also serves as an effective continuation of the material mixing and reaction process. This allows the atomized swirling material to be further fully mixed and continuously reacted within the connecting chamber 22, resulting in more thorough mixing and reaction, and further improving reaction efficiency and product quality. Subsequently, the upper-wide and lower-narrow conical gas-liquid separation mesh 29 increases the gas-liquid contact area, allowing liquid droplets to fully collide, coalesce, and flow downwards under gravity, collecting through the overflow pipe 27. The separated gas then enters the exhaust valve 211 through the connecting pipe 210. The material is stably discharged through exhaust pipe 212, ensuring a stable reaction environment pressure. After the reaction is complete, the material enters long pipe 213 through overflow pipe 27, and then connects to external pipelines or subsequent reactors through discharge pipe 214 via flange to achieve stable discharge. The signal detection probe installed on the self-control probe installation pipe 216 monitors the gas-liquid feed parameters in real time, facilitating timely adjustment and ensuring reaction stability. When the device needs maintenance or shutdown, the residual liquid inside is emptied through the discharge valve of the discharge valve sealing plate 215 to prevent material residue from corroding the device. Throughout the process, the mixing reaction chamber 21 and the connecting chamber 22 are connected. The first sealing ring between the connecting chamber 22 and the gas-liquid separation chamber 23, the third sealing ring between the overflow pipe 27 and the mixing reaction chamber 21, the fourth sealing ring between the gas-liquid separation chamber 23 and the connecting pipe 210, and the fifth sealing ring between the long pipe 213 and the discharge valve sealing plate 215 work together to comprehensively ensure the airtightness of the device and prevent material leakage. Simultaneously, the number of mixing reaction chambers 21 with corresponding atomizing nozzles 24 can be replaced according to process requirements, adapting to multi-material mixing, reaction, and crystallization processes, achieving efficient, stable, and controllable gas-liquid atomized swirling mixing reaction.
