Description

Technical Field

[0001] This application relates to the field of chemical equipment, and more particularly to a stirred tank reactor. Background Technology

[0002] In the field of chemical preparation, existing stirred tank reactors are widely used for processing solid-liquid, liquid-liquid, and systems with exothermic / gas release. They generally consist of a tank body, stirring drive, feeding and venting / discharging interfaces, and temperature control components, and are common general-purpose mixing reaction equipment in factories.

[0003] To ensure normal operation, a central stirring system is typically used to form a circulation, with a single-point feed inlet on the side wall or top cover, and exhaust and discharge outlets on the top cover and lower side. Heat exchange is achieved through a jacket / coil. To improve mixing efficiency, the stirring speed or power needs to be increased. To facilitate step-by-step feeding, materials are often introduced directly into the vessel from the side wall or top in a free jet manner. To ensure continuous production and safety, it is necessary to maintain unobstructed exhaust and discharge, relying on conventional temperature / pressure detection and interlocking methods. As a result, the flow inside the vessel is mainly dominated by the central vortex and the wall-mounted backflow, leading to insufficient coupling between the feed jet and the main circulation.

[0004] Based on the above layout and operation mode, the existing technology generally has the following technical problems: the material in the reactor is prone to stratification and severe eddy currents, resulting in poor mixing uniformity and long mixing time; during the step feeding process, it is difficult to achieve volume dispersion and dilution in the feed neighborhood in a timely manner, which leads to excessively high local concentration / temperature during feeding, affecting process safety and product consistency. Utility Model Content

[0005] Therefore, it is necessary to propose a stirred tank reactor to address the above problems.

[0006] Embodiments of this application provide a stirred tank reactor, comprising: The vessel body forms a cavity with an axis. A channel guide is an arc-shaped baffle disposed on the inner wall of the vessel, with openings at both ends between the baffle and the inner wall, the openings being continuous along the axial direction. A flow guiding assembly is disposed within the receiving cavity and located at the center of the receiving cavity. The channel guide and the flow guiding assembly together form a circulating channel extending along the axis within the receiving cavity. The feeding section is located on the side wall of the vessel body and communicates with the receiving cavity; A flow-dissipating component is fixed to the inner wall of the vessel.

[0008] In at least one embodiment of this application, the arcuate opening of the channel guide faces the flow guiding assembly; The channel guide is provided with a gap extending along the axis between it and the inner wall of the vessel.

[0009] In at least one embodiment of this application, the feeding section is a straight short section that passes through the side wall of the vessel body, the inner end of the short section being flush with the inner wall of the vessel body and opening directly into the wall-mounted channel between the channel guide and the inner wall of the vessel body.

[0010] In at least one embodiment of this application, the turbulence component includes a substrate and a plurality of bosses spaced apart along the axis, wherein the leading edge of the bosses is an arc surface.

[0011] In at least one embodiment of this application, at least one set of the turbulence components is disposed inside the feed section and located between the feed section and the circulation channel.

[0012] In at least one embodiment of this application, it further includes a discharge section, a sampling section, an exhaust gas section, an instrument section, and a maintenance and installation section that are in communication with the receiving cavity; The discharge section is located on the side wall of the vessel and communicates with the receiving cavity; The sampling section is located on the side wall of the vessel body and is positioned above the side wall of the discharge section, and is in communication with the receiving cavity; The exhaust gas section is disposed on the top cover and communicates with the receiving cavity; The instrument section is located on the top cover, has a straight-through structure, and communicates with the receiving cavity; The maintenance and installation part is located on the top cover and in the axial region of the receiving cavity.

[0013] In at least one embodiment of this application, a liquid baffle is provided on the inner side of the exhaust gas section. The liquid baffle is a wall-mounted arc-shaped cover plate with a single-end opening, which is attached to the inner wall of the top cover and arranged around the inner opening of the exhaust gas section, and communicates with the exhaust gas section. Its opening faces the bottom of the vessel body.

[0014] In at least one embodiment of this application, the sampling section is an upwardly extending straight section welded to the side wall of the vessel body, the outer end of the sampling section is a quick-connect connector, and the inner end of the sampling section is flush with the inner wall of the vessel body.

[0015] In at least one embodiment of this application, the discharge section is a radially straight short section, the inner end of which is flush with the inner wall of the vessel and communicates with the receiving cavity; The outer end of the short section is provided with a flange; The discharge section also includes a blind flange, which is detachably and sealed to the flange, and a handle is provided on the outside of the blind flange.

[0016] The stirred tank reactor described above utilizes a wall-mounted arc-shaped channel guide and an axial flow guiding component to form a continuous axial circulation channel within the reactor. This allows the material to rise within the channel and fall back outside, breaking the central vortex and eliminating stratification, thereby improving mixing uniformity and shortening mixing time. The side-wall feed section, in conjunction with the inner turbulence-inducing component, first disperses the feed jet and guides it into the circulation channel, achieving rapid volume dispersion and dilution. This significantly reduces local concentration and temperature peaks during feeding, avoiding hot spots and side reactions. Attached Figure Description

[0022] Please see Figure 1 , Figure 2 and Figure 3 In this embodiment, a stirred tank reactor 100 comprises a vessel body 10, a receiving cavity 11, a channel guide 20, an opening 21, a flow guiding assembly 30, a feed section 12, and a turbulence-inducing assembly 40. The vessel body 10 is a cylindrical shell equipped with a top cover 13, the two being sealed together to form the receiving cavity 11; the geometric centerline of the receiving cavity 11 is located at... Figure 2 The axis A is shown in the center and serves as a directional reference for structural installation and flow description. This enclosed cavity is used to withstand the pressure and temperature loads generated during stirring and heat exchange, providing a closed space for subsequent organized circulation.

[0023] In one specific embodiment, the channel guide 20 is fixed to the inner wall of the vessel body 10. The channel guide 20 is an arc-shaped baffle extending along axis A, with its arc surface facing the central area of ​​the receiving cavity 11. Openings 21 are provided at the upper and lower ends of the channel guide 20 between it and the inner wall. The openings 21 are continuous along axis A, allowing the narrow wall-attached channel defined between the arc-shaped baffle and the inner wall to communicate with the main cavity space at both the upper and lower ends. This arrangement aims to organize the originally disordered wall-attached backflow into a continuous axial path from top to bottom, reducing wall-attached stagnation, weakening the central vortex, and promoting continuous exchange between the upper and lower layers of the cavity. This directly improves the problems of easy material stratification and severe eddy currents, laying the flow foundation for shortening the homogenization time.

[0024] Furthermore, the channel guide 20 is fixed to the inner wall of the vessel body 10 by welding to ensure stable shape and position and facilitate assembly.

[0025] In one specific embodiment, the flow guiding component 30 is disposed within the receiving cavity 11 and located in the central region along axis A. The flow guiding component 30 and the channel guide 20 together form a circulating channel extending along axis A within the cavity. The function of the flow guiding component 30 is to geometrically converge and guide the backflow in the central region and near the bottom, drawing the backflow into the aforementioned narrow channel against the wall and causing it to rise along axis A, thereby forming a main circulation that flows upward within the channel and falls back outside the channel, reducing short-circuit flow and dead zones at the bottom and suppressing the large central vortex.

[0026] In one specific embodiment, the flow guiding component 30 is a U-shaped frame baffle with its opening facing the channel guide 20 and maintaining a gap with the bottom of the vessel body 10, so as to improve the volume circulation volume and circulation stability with less resistance loss.

[0027] In one specific embodiment, the feed section 12 is disposed on the side wall of the vessel body 10, and adopts a through-wall straight section 51 structure. Its outer end is used for a sealed connection with an external feeding pipe; the inner port opens directly into the wall-adhering channel defined by the channel guide 20 and the inner wall of the vessel body 10. The inner end of the feed section 12 is located on the side of the arc surface of the channel guide 20 adjacent to the upper end and the lower end opening 21, so that the incoming material does not enter the main space of the receiving cavity 11 in a free jet manner, but enters the wall-adhering channel in situ. Preferably, in order to avoid significantly affecting the flow cross-section of the wall-adhering channel, the feed section 12 is a through-wall straight section 51 that passes through the side wall of the vessel body 10, with its inner end flush with the inner wall of the vessel body 10, and its inner port opening directly into the wall-adhering channel defined by the channel guide 20 and the inner wall of the vessel body 10, without obstructing the arc surface boundary of the channel guide 20.

[0028] Furthermore, the turbulence-disrupting component 40 is fixed to the inner wall of the vessel body 10 and located adjacent to the inner end of the feed section 12, so that the fluid entering the wall-attached channel from the feed section 12 first undergoes shear disturbance when flowing through this location and is guided in the upward direction along axis A.

[0029] In one specific embodiment, the channel guide 20 is fixed to the arc-shaped baffle on the inner wall of the vessel 10, forming an extended wall-adhering channel with the inner wall. Openings 21 are provided at its downstream end, connecting the wall-adhering channel to the upper and lower spaces of the receiving cavity 11. The inner end of the feed section 12 directly interacts with the wall-adhering channel. After external flow enters, it is confined by the channel guide 20 and, under the suction and guidance of the flow guiding assembly 30, moves upward along axis A, thus quickly merging into the main circulation of upward flow within the channel and downward flow outside the channel. The path and time for the feed to merge into the main circulation are shortened, reducing local concentration peaks and instantaneous temperature increases near the feed port and vessel 10 during step-by-step feeding. Furthermore, it avoids direct large-scale vortices and wall backflow formed by free jets entering the main space, weakening stratification at the source and improving volumetric dispersion efficiency. For solid-liquid mixing, exothermic feeding, or feeding accompanied by venting, the above-mentioned feeding method of introducing the feed into the wall-mounted channel and moving upwards can allow heat and concentration to accumulate in the main circulation and be carried away in time, reducing the risk of side reactions and local overheating, and improving process safety and batch stability.

[0030] In one specific embodiment, the turbulence-disrupting component 40 is fixed to the inner wall of the vessel body 10 to provide disturbance to the wall-attached flow and the jet entering from the feed section 12 and guide them into the circulation channel. The turbulence-disrupting component 40 accelerates volume dispersion and further suppresses large-scale vortices by changing the local boundary layer state, cutting the jet, and deflecting the flow direction, thereby disrupting the stable wall-attached return surface and local vortices.

[0031] Furthermore, the turbulence component 40 is arranged along axis A, and several turbulence units are set along the axial direction to obtain a continuous turbulence effect under the premise of low drag.

[0032] In one specific embodiment, after power-on, initial liquid is added to or introduced into the receiving cavity 11, and stirring and related operating conditions are activated. Under the combined action of the flow guiding component 30 and the channel guide component 20, the fluid flows from bottom to top along the circulation channel. After entering the upper space of the cavity through the upper opening 21, it falls back to the central area and is then guided by the flow guiding component 30 to the lower opening 21 of the channel to continue upward, forming a stable main circulation with axis A as the direction. When the feed is added in stages through the feeding section 12, the feed is dispersed and redirected at the turbulence component 40, and then quickly swallowed by the main circulation and evenly dispersed throughout the receiving cavity 11. During the entire process, the central vortex is suppressed, stratification is continuously broken, the time to reach the target uniformity is shortened, and the concentration and temperature peaks in the feeding area are significantly reduced.

[0033] Furthermore, based on this, the embodiments of this application first utilize the channel guide 20 and the opening 21 to define a narrow channel through axis A on the inner wall, solving the problems of wall stagnation and stratification; secondly, a flow guiding component 30 is arranged in the area of ​​axis A to gather the backflow and guide it into the narrow channel, forming a closed and stable macroscopic circulation, reducing the central eddy and bottom short-circuit flow; then, the feed section 12 and the turbulence component 40 are path-coupled, so that the feed is disturbed on-site and quickly incorporated into the main circulation, thereby weakening the local concentration / temperature peaks caused by step feeding from a mechanistic perspective. This purely structured solution can improve mixing uniformity and shorten mixing time at the same stirring power without additional energy input or complex control.

[0034] In one specific embodiment, the flow guiding component 30 is disposed in the central region of the receiving cavity 11 along axis A. The flow guiding component 30 adopts a U-shaped frame-type flow guiding baffle structure, with the U-shaped opening facing the arc surface of the channel guide 20. The two side frames of the U-shaped frame extend along axis A and together with the channel guide 20 form a continuous circulation channel within the cavity. A gap is left between the lower edge of the U-shaped frame and the bottom of the vessel body 10 to avoid forming a tight seal with the bottom of the vessel and to provide a channel for the backflow near the bottom to enter the interior of the U-shaped frame.

[0035] Furthermore, during operation, the fluid falling from the upper part of the cavity to the central region and near the bottom first enters the U-shaped frame from below through the gap. After being geometrically converged by the side frame of the flow guiding component 30, it rises along axis A and is directed towards the channel guide 20 through the U-shaped opening, communicating with the wall-adhering channel defined between the channel guide 20 and the inner wall of the vessel body 10. The U-shaped frame arrangement combined with the bottom gap improves the interception capability of the falling flow in the central region and bottom, reducing bottom short-circuit flow and stagnant dead zones. On the other hand, it increases the volumetric circulation rate and circulation stability without significantly increasing resistance loss, which is beneficial for suppressing the central eddy and shortening the homogenization time.

[0036] In one specific embodiment, the channel guide 20 is fixed to the inner wall of the vessel body 10. The channel guide 20 is an arc-shaped baffle with its arc-shaped opening facing the flow guide assembly 30 located in the central region of the receiving cavity 11. A gap extending along axis A is left between the channel guide 20 and the inner wall of the vessel body 10. This gap fits with the inner wall to form a wall-attached channel section, and openings 21 are left at the upper and lower ends of the channel guide 20 and the inner wall, respectively, so that the wall-attached channel communicates with the main cavity space at the upper and lower ends.

[0037] Furthermore, the combination of the arcuate orientation and axial clearance allows the fluid falling from the central region to be directed into the wall-attached channel with minimal turning loss under the guidance of the flow guide component 30, and to flow upward along axis A. Wall-attached stagnation and backflow are reduced, while vertical exchange near the wall is enhanced, thereby suppressing stratification and large-scale central vortices, and shortening the time to reach the target uniformity. These effects can be achieved simply by adjusting the orientation and clearance of the channel guide component 20, without requiring additional components or control measures.

[0038] In one specific embodiment, the turbulence-disrupting assembly 40 includes four sets of turbulence-disrupting assemblies 40 spaced circumferentially along the inner wall of the vessel body 10, with the four sets distributed approximately equidistantly around axis A. Each set of turbulence-disrupting assemblies 40 has a base plate 41 attached to the wall, and several protrusions 42 are arranged at intervals along axis A on the base plate 41, with the leading edge of each protrusion 42 being a sloped or arc-shaped surface. The four sets of turbulence-disrupting assemblies 40 work together in the circumferential direction, causing the fluid skimming against the wall to encounter the leading edges of the sloped / arc-shaped protrusions 42 in sequence along the axial direction, resulting in continuous shearing and moderate deflection, forming four turbulence bands extending along axis A with low resistance. This arrangement can, on the basis of the main circulation established by the channel guide 20 and the flow guiding assembly 30, take into account the near-wall turbulence coverage in each quadrant of the circumference, weaken the wall-attached backflow surface and local vortices, reduce the risk of wall-attached stagnation and stratification, and accelerate the main circulation of material entering the wall-attached channel from the feed section 12 and flowing upward into the channel and falling back outside the channel.

[0039] Preferably, at least one set of turbulence components 40 is disposed inside the feed section 12, between the feed section 12 and the wall-mounted channel defined by the channel guide 20, so that the feed material first obtains continuous shearing and guidance and then quickly merges into the axial upward flow, reducing the instantaneous concentration / temperature peak in the feeding area, and cooperating with the other three sets in the circumferential direction to further suppress the central eddy, shorten the homogenization time, improve batch consistency and process safety.

[0040] In one specific embodiment, at least one set of the turbulence-disrupting components 40 is arranged inside the feed section 12 and located between the feed section 12 and the circulation channel defined by the channel guide 20 and the inner wall of the vessel body 10. This set of turbulence-disrupting components 40 includes a base plate 41 attached to the wall and a plurality of protrusions 42 spaced apart along axis A, each protrusion 42 having a beveled or arc-shaped leading edge. During operation, external material injected from the feed section 12 first passes over this set of turbulence-disrupting components 40. The jet is continuously sheared and moderately deflected by the protrusions 42, forming an upward turbulence band along axis A. Subsequently, under the suction and guidance of the flow guiding component 30, it is incorporated into the main circulation that flows upward within the channel and then falls back outside the channel. This positional coupling enables the feed to be crushed and flowed together within a short stroke, significantly reducing the instantaneous concentration / temperature peak in the feed neighborhood, shortening the path and time for it to enter the main circulation, and working in conjunction with other circumferential turbulence components 40 to weaken wall retention and local vortices, thereby suppressing stratification and large-scale central vortices from a mechanistic perspective.

[0041] In one specific embodiment, the stirred tank reactor 100 is further provided with an interface communicating with the containment cavity 11, including a discharge section 50, a sampling section 70, an exhaust gas section 60, an instrumentation section 80, and a maintenance and installation section 90. The discharge section 50 passes through the side wall of the reactor body 10 and communicates with the lower region of the containment cavity 11. Its axial direction is generally outward along the normal direction of the reactor body 10, forming a short and straight discharge path to facilitate rapid venting of materials and cleaning liquid. The sampling section 70 also passes through the side wall of the reactor body 10, positioned higher than the side wall of the discharge section 50 and communicating with the containment cavity 11, for process sampling. Its circumferential position is offset from the feed section 12 and the channel guide 20 to avoid interference from the feed jet or the main circulation along the wall on the sample representativeness. The exhaust gas section 60... The feed section 12, channel guide 20, and flow guide 30 are located on the top cover 13 and communicate with the receiving cavity 11, providing an interface for the discharge of non-condensable gases and connection to the external condensation / absorption system. The instrument section 80 is located on the top cover 13, with a straight-through structure and communicating with the receiving cavity 11, facilitating the installation of temperature, pressure, or liquid level detection elements and enabling forward and reverse flushing during on-site cleaning. The maintenance and installation section 90 is located on the top cover 13 and in area A of the axis of the receiving cavity 11, providing for the assembly and maintenance of core components such as the stirring shaft and the flow guide assembly 30, as well as for visual inspection and tool entry within the cavity. The above interfaces are staggered in height and circumference from the arrangement of the feed section 12, the channel guide 20, and the flow guide assembly 30, ensuring both the continuity and stability of the main circulation channel and facilitating external piping and CIP operations.

[0042] In one specific embodiment, a liquid-blocking hood 61 is provided on the inner side of the exhaust gas section 60. The liquid-blocking hood 61 is a wall-mounted, arc-shaped hood with a single-end opening, fixed against the inner wall of the top cover 13, and arranged around the inner opening of the exhaust gas section 60, and communicating with the exhaust gas section 60. The opening of the liquid-blocking hood 61 faces the bottom of the vessel body 10. During operation, droplets and bubbles rising with the airflow are first intercepted by the liquid-blocking hood 61, condensed into a film, and flow back into the vessel along the inner wall of the top cover 13, reducing the risk of droplets being carried out by the exhaust gas, thereby reducing material loss and exhaust gas treatment load; the hood is arranged against the wall and only has a single-end opening, so it does not significantly disturb the main circulating gas-liquid flow near axis A.

[0043] In one specific embodiment, the sampling section 70 is an upward-facing straight-through short section 51 welded to the side wall of the vessel body 10. The outer end of the sampling section 70 is a quick-connect fitting port, which facilitates quick docking with the sampling valve or hose; its inner end is flush with the inner wall of the vessel body 10, and does not form an insertion tube into the receiving cavity 11. This upward-facing straight-through and flush-end structure helps to reduce the volume of stagnation and scale points, suppresses dripping and siphoning after the valve is closed, and facilitates the operator to place the container below the valve port to complete safe sampling; at the same time, the height arrangement of the sampling section 70 relative to the discharge section 50 facilitates keeping the sampling channel clean during discharge and CIP operation.

[0044] In one specific embodiment, the discharge section 50 is a radially straight short section 51. The inner end of the short section 51 is flush with the inner wall of the vessel body 10 and communicates with the receiving cavity 11, avoiding the formation of protruding dead corners on the inner wall; the outer end of the short section 51 is provided with a flange 52 for sealing connection with the discharge valve or the flange of the external pipeline. To accommodate the needs of shutdown, handling, or maintenance, a blind flange 53 is provided. The blind flange 53 is detachably connected to the flange 52 by bolts to close the discharge section 50. A handle 54 is provided on the outer side of the blind flange 53 for easy loading and unloading. This short and straight discharge channel with a flush inner end can significantly shorten the discharge time and reduce the volume of residual liquid against the wall; for materials containing solids or easily settling materials, it is also beneficial to reduce the accumulation of sediment and reduce the agitation intensity required for resuspension, thereby improving the efficiency and safety of shutdown switching and CIP cleaning.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
