It has disadvantages such as high fuel consumption and frequent mechanical failures. (Blistering) reactors that do not require large-scale stirrers, mild reactions, low material It has advantages such as low consumption and no energy consumption. However, Due to the conventional feeding mode and gas disperser adopted in bubbling reactors, 30 Ensuring an even distribution of materials and gases entering the reactor interior is challenging. This situation leads to an uneven distribution of the temperature field and the reaction field. This situation leads to the formation of vortices that affect the circulation flow of materials within the reactor. There is a tendency for the reaction to open, resulting in increased material consumption. 2 insufficient resources and rising production costs, thus affecting product quality and economic efficiency. The benefits are negatively affected. In one configuration, as shown in Figure 1, the bubbling reactor is positioned vertically. a reactor shell (100) and inside the reactor shell (100) and on its base 5 It includes a ring-shaped gas distributor (300) located nearby.

Because of its location, the area near the base of the reactor shell (100) contains abundant gas (e.g. (contains air) and violent reactions occur, but the reaction It is unable to receive timely replenishment of its materials. This situation affects the reactor body (100) This leads to an extremely high local reaction temperature inside, and side effects. It can accompany the reactions. In contrast, the material inside the reactor shell (100) is 20 The region near the inlet has a low gas content (e.g., air), which affects the reaction. This is unfavorable. In addition, local vortices occur inside the reactor shell (100). can be reached. In addition, the large amount of reaction material (cold) in this region (environment), causes a locally low temperature and inside the reactor shell (100) This further exacerbates the uneven distribution of the temperature field and the reaction field. 25 In this technique, the temperature field and the reaction field are uneven in the multiphase reactor. regarding the problem of how distribution affects reaction efficiency and increases material consumption So far, no effective solution has been proposed. Therefore, based on years of experience and practices in the relevant industry, the invention The developer proposes a multi-phase reactor to address the shortcomings of the previous technique.

The directional terms such as "top", "bottom", "peak", "base" and "vertical" used in the current explanation All are defined by reference to the orientations shown in Figure 2. These terms are used here. As stated, it aims to define spatial relationships more clearly, in practice. It does not limit orientations. As shown in Figures 2 to 5, the current description includes a reactor shell (1), a gas diffuser and provides a multiphase reactor containing at least one circulation tube (2). Reactor shell A reaction chamber (101) is constructed inside (1). Reaction chamber (101) is vertical It is a cylindrical chamber placed on the reactor body (1), the reaction a primary material inlet channel (7) and a 30 in fluid communication with the reservoir (101).

It aims to preserve the structure, the types of primary and secondary materials. It does not limit. 30 In an optional configuration of the current statement, as shown in Figure 2, the first The outlet end of the material inlet channel (7) extends to the inside of the circulation pipe (2). On the other hand, this situation is around the outer perimeter of the second gas distributor (6) of the first material. 9 This allows for the distribution of the ratio between the primary and secondary materials. This makes it easier to adjust. This situation ensures that the second material (e.g., air) is sufficient. This allows it to immediately chemically react with a sufficient amount of the primary material, thus excessive chemical reactions resulting from an excess of the second material (e.g., air) and This reduces the intermediate products formed as a result, the second material (e.g., air) 5 It minimizes the amount of feed, reduces production costs, and is economical. This ensures the benefits. On the other hand, this situation affects the reaction position of the reactor. It places the reactor away from the inner wall surface of the body (1), so that the reactor excessive local thermal stress at the discontinuity points on the inner wall surface of the body (1) This prevents and consequently reduces local material failure and equipment instability. It prevents him from working. In addition, as shown in Figure 2, the first material inlet channel (7) and the second material inlet Channel (8) is arranged along the axial direction of the reaction chamber (101). First The material inlet channel (7) is located in the middle-lower part of the reaction chamber (101) and the second 15 The material inlet channel (8) is located at or near the bottom of the reaction chamber (101). There is a relative first material inlet channel (7) and a second material inlet channel (8). its arrangement as the medium inside the reaction chamber (101) the reaction chamber (101) This arrangement ensures that the flow occurs along the axial direction. In addition, this arrangement is made with the circulation pipe (2). By working together, we can further improve the axial flow of the medium inside the reaction chamber (101). It directs at the level. In addition, the ventilation on the circulation pipe (2) The sections function to cut and break up the medium, thus creating a mixing effect. It increases the efficiency and speed of mixing the medium, and the reaction. It improves its performance. In addition, the gas distributor has a second material inlet channel (8) Axial distribution of the second material conveyed by 25 inside the reaction chamber (101) It makes things easier. In an optional configuration of the current description, as shown in Figures 2 through 5, circulation pipe (2), a vertically arranged cylindrical pipe with open top and bottom ends It is a pipe, placed coaxially with the reactor body (1). Multiple vents 30 The section is distributed intermittently along the circumferential aspect of the circulation pipe (2). Multiple ventilation sections are neatly arranged on the circulation pipe (2). can be distributed or their distribution locations are to the first material inlet channel (7) They can be adjusted according to their distances, so multiple ventilation sections can be properly positioned. It can be distributed in a non-reactive manner. The basic requirement is that the ventilation sections react. to ensure adequate radial flow direction for the first material entering the reservoir (101) It provides security. In addition, as shown in Figures 2 and 5, the number of circulation tubes (2) is more than one 5 all of these are arranged coaxially with the reaction chamber (101) and They are placed at equal intervals along the axial direction of the reaction chamber (101) (i.e., The distance between any two adjacent circulation pipes (2) is equal). The bottommost The base end surface of the circulation pipe (2) is the weld of the base cap of the reactor body (1). It is positioned higher than its source line. Circulation 10 The number of tubes (2) is determined according to the height of the reaction chamber (101), reaction chamber (101) to provide overall radial flow orientation for the medium inside and reaction performance It can be adjusted to maximize efficiency. Any two adjacent circulation pipes. (2) The vertical spacing between them shall be equal according to actual settlement requirements It is adjustable. 15 In an optional configuration of the current statement, as shown in Figure 2, The diameter of the circulation tube (2) is smaller than the diameter of the reactor shell (1), first The inlet end of the material inlet channel (7) is located outside the reactor shell (1) and the first The outlet end of the material inlet channel (7) extends to the inside of the circulation pipe (2). 20 The cross-sectional area of ​​the circulation tube (2) is equal to the cross-sectional area of ​​the reactor shell (1). It can be adjusted to approximately 50% to 75% or the circulation pipe (2) its diameter shall be approximately 70 to 86% of the diameter of the reactor shell (1) It is adjustable. The current description provides two structural configurations of the circulation pipe (2). One of the structural configurations of the flow circulation pipe (2) is as follows: In Figure 3 As shown, the circulation pipe (2) runs along the circumferential side of the reaction chamber (101). Multiple partition plates with intermittently arranged arc-shaped cross-sections (201) 30 It is structured. Multiple partition plates (201) are connected by means of connecting elements (3). It is attached to the inner wall of the reactor shell (1). To configure the ventilation section. the inner and outer parts of the circulation pipe (2) between adjacent partition plates (201). A gap (202) is left between them, providing fluid communication. Partition plates (201), 11 The reaction chamber shall be constructed in such a way that gaps (202) are left between adjacent partition plates (201). (101) can be arranged neatly by taking the axis as the center line. Each The upper parts of the multiple partition plates (201) that structure the circulation pipe (2) are horizontal They are aligned as follows, and their bases are also horizontally aligned. Suddenly... excess space (202), in order to maximize reaction efficiency, uniformly 5 can be distributed or gaps (202) and the inlet end of the first material inlet channel (7) unevenly depending on the distance or degree of reaction It can be distributed. The circulation pipe (2) can be connected to the reactor via connecting elements (3). It is fixed to the inner wall of the body (1). The number of fasteners (3) is the partition It is equal to the number of plates (201) and corresponds to them one by one. The existing 10 In a specific configuration of the description, the number of circulation pipes (2) is two It is possible to configure each circulation pipe (2) with six partition plates (201). and at the same time the number of corresponding connecting elements (3) is six, each connecting element (3) fixes a partition plate (201) to the inner wall of the reactor shell (1). Actual During assembly, the fasteners (3) are first mounted on the reactor shell (1) 15 can be done and then multiple partition plates (201), respectively the corresponding connection elements (3) are mounted on it. Another structural configuration of the circulation pipe (2) is as follows: In Figure 4 As shown, the circulation tube (2) is placed inside the reaction chamber (101) 20 It is a cylindrical tube (203). The tube (203) is along the circumferential direction of the tube (203). to the inner wall of the reactor body (1) by means of multiple distributed fastening elements (3) It is connected. In order to configure the ventilation sections, it is on the pipe (203) Multiple ventilation holes (204) or vents are placed intermittently along the circumferential direction. The vent is arranged. Multiple ventilation holes (204) or ventilation vents, 25 It can be evenly distributed to maximize reaction efficiency. or the distance between these and the inlet end of the first material inlet channel (7) or reaction It can be distributed unevenly depending on the degree. The number of connecting elements (3) It is equal to or greater than 2 and is to ensure the stable assembly of the pipe (203). It is arranged uniformly along the circumferential direction of the pipe (203). 30 In the current explanation, gaps (202) on the circulation pipe (2) are used for ventilation. Providing holes (204) or ventilation vents, reaction chamber (101) the medium flowing axially in the reaction chamber (101) radially 12 This also makes it possible for the flow to occur in that direction, allowing the multiphase medium to be interrupted again. It carries out the decomposition and the separation between the first and second materials. It enhances the mixing effect, thereby strengthening radial circulation and traditional This changes the situation where axial circulation dominates the flow field in reactors. This prevents problems such as local viscous flow and low mixing efficiency. 5 Arrangement of the circulation pipe (2) can also weaken the wall effect, It can reduce the radial temperature gradient and also improve the heat transfer efficiency by mass. It significantly improves performance. In an optional configuration of the current statement, as shown in Figures 1 and 5, 10 The gas distributor is a first gas in contact with the fluid through the second material inlet channel (8). It includes a first gas distributor (4) and a second gas distributor (6). The first gas distributor (4) is the reaction It is a circular hollow structure placed along the circumferential direction of the reservoir (101) (first gas dispenser (4) which can also be called an annular gas dispenser) and It is provided in more than one first gas hole (401). Second gas distributor (6), reaction 15 It is a hollow tube-shaped structure extending along the axial direction of the reservoir (101) (second gas distributor (6) which can also be called an axial gas distributor) and more than The second gas hole (601) is provided. The first gas distributor (4) and the second gas distributor (6) are one The second material is in fluid communication with each other via the connecting channel (5). The second material (e.g. air) conveyed by the inlet channel (8) goes to the first gas distributor (4) and 20 The second gas enters the distributor (6), so that the reaction chamber of the second material (101) It ensures distribution along the circumferential and radial directions within the reaction chamber. (101) makes the distribution of the second material inside more uniform. The first gas By means of the operation of the distributor (4) and the second gas distributor (6) together, from the first gas hole (401) and the second material is fed into the reaction chamber (101) through the second gas hole (601), 25 It exists in the form of numerous small bubbles ranging from 2 mm to 15 mm in diameter. As a result, while the feed rate of the second material remains constant, the structure is determined by the second material. The surface area of ​​the bubbles is effectively increased, thus combining the second material with the first. The contact area between the materials is increased, reaction efficiency is improved, and more A comprehensive response is ensured. 30 In addition, as shown in Figures 2 and 5, both the first gas diffuser (4) and the second gas The distributor (6) can be placed coaxially with the reactor shell (1). 13 In an optional configuration of the current statement, there are multiple first gas holes (401), It can be distributed evenly on the first gas distributor (4), but in different regions (e.g., first gas holes at different axial heights (401)) first gas holes (401) The cross-sectional areas can be different. More than one second gas hole (601), second gas It can be distributed evenly on the distributor (6), but in different regions (e.g. 5 the transverse of the second gas holes (601) at different axial heights Their cross-sectional areas can vary. In this configuration, the number of first gas distributors (4) is one, as shown in Figures 2 and 5. There are more of these, a base gas located below the lowest circulation pipe (2) 10 It includes the distributor and the intermediate gas distributors located between the adjacent circulation pipes (2). Base gas distributor and intermediate gas distributors supply second gas via connection channel (5) respectively. The base gas distributor and the second gas distributor are in fluid communication. The connecting channel (5) between (6) is located away from the axis of the reaction chamber (101). It is inclined upwards in the direction of the axis of the reaction chamber (101). 15 The angle between the axis of the connecting channel (5) and the axis of the reaction chamber (101) is greater than 0°. and is less than 90°. Circulation pipe (2), first gas distributor (4) and second gas axial reaction in conventional multiphase reactor through the operation of the distributor (6) The distribution is altered, effectively improving reaction uniformity in all directions. is being improved, the axial temperature gradient is being greatly reduced, and raw material utilization is 20%. The rate is maximized and production costs are reduced. In addition, the first gas distributor (4) is in fluid communication with the second gas distributor (6) The number of connecting channels (5) is more than one and connecting channels (5) are the first gas 25 at regular intervals along the circumferential side of the distributor (4) and the second gas distributor (6) is arranged. Alternatively, at the same time, multiple connection channels (5), first gas ensuring a stable connection between distributor (4) and second gas distributor (6) Provided that, it can be distributed unevenly. Furthermore, as shown in Figures 2 and 5, the diameter of the base gas distributor is 30 cm from the circulation pipe. (2) is equal to or less than the inner diameter and the diameter of the intermediate gas distributor is circulation The outer diameter of the pipe (2) is equal to or greater than that of the base gas. This situation affects both the base gas the second material discharged from the distributor and the intermediate gas distributor, circulation pipe (2) being able to smoothly enter the annular flow region surrounding its outer perimeter 14 This ensures that the flow direction of the discharged secondary material is as shown in Figure 5. The medium inside the reaction chamber (101) must be compatible with the general circulation flow direction. This is the reason why reaction efficiency is improved. In an optional configuration of the present description, the axial 5 of the reaction chamber (101) Along its direction, the base of the second gas distributor (6) connects to the base gas distributor via the connecting channel (5). It is in fluid contact with the second gas distributor (6), the circulation pipe (2) It passes through, the upper part of which is at least opposite to the first material inlet channel (7) or It extends to a location adjacent to this, so that the second gas is discharged from the second gas distributor (6). the material is distributed uniformly along the axial direction of the reaction chamber (101) and 10 to ensure thorough mixing with the primary material and thus It improves reaction efficiency. In addition, there is more than one first material inlet channel (7), these are the reactors It is arranged at intervals along the circumferential direction of its body (1) and has more than one first 15 All outlet ends of the material inlet channel (7) are placed inside the circulation pipe (2). It extends between the outlet end of the second gas distributor (6) and the first material inlet channel (7). The distance is 0.6 to 0.8 times the radius of the reactor shell (1). Conventional multiphase In reactors, the outlet end of the material inlet channel is located very far from the gas inlet, This situation leads to an excessively long reaction time. As a result, the gas is not sufficiently 20 It does not come into immediate contact with the material, which leads to an excessive amount of gas at the gas inlet. opening the reactor and causing an overreaction that produces large amounts of intermediate products. It reduces its efficiency. In the current explanation, the circulation of the first material input channel (7) Extending the tube (2) to the inside of the tube effectively reduces these factors and the reaction It significantly improves its efficiency and quality. In addition, the first material and 25 If heat is generated during the reaction between the second material, then heat is also generated at the same time as the first. Extending the material inlet channel (7) to the inside of the circulation pipe (2), reaction It keeps the local material area away from the inner wall surface of the reactor shell (1), thus preventing local material from accumulating. excessive local conditions that could lead to malfunction and affect the stable operation of the multi-phase reactor It prevents thermal stress. 30 In an optional configuration of the current statement, as shown in Figures 2 and 5, To remove drifting mist and droplets, at the top of the reaction chamber (101) or A fog suppressor (9) is placed inside it in a nearby location. The characteristics and advantages of the multi-phase reactor described in the current explanation are as follows: 1. In a multi-phase reactor, the reactor shell (1) is the axial position of a medium inside the reactor shell (1). It is provided in a circulation tube (2) to promote flow. 5 of the reactor shell (1) circulation pipe along the circumferential direction (2) multiple ventilation sections on it It is placed and cuts off the flowing medium inside the reaction chamber (101) and It breaks down, thus causing the polyphase medium to be cut and broken down again. It performs, enhances the mixing effect, inside the reaction chamber (101) It effectively eliminates local viscous flow and allows the medium to be processed more efficiently and quickly. 10 It facilitates mixing. In addition, the wall effect can be reduced, and the mass of the environment can be adjusted. and heat transfer can be enhanced and reaction performance improved. 2. In a multi-phase reactor, by means of the combined use of the gas distributor and circulation tube (2), The first and second materials are distributed more evenly, so the reaction is 15 while the temperature gradient in the reservoir (101) is effectively reduced and excessive local thermal stress is avoided While avoiding certain things, reaction efficiency is maximized. As a result, the reaction area is made more uniform, the reaction in the reaction chamber (101) is more comprehensive This can be achieved by improving the reaction efficiency of the multi-phase reactor. Raw material consumption is effectively reduced, and the reaction operates safely and stably. 20 is provided. 3. In the multi-phase reactor, the first gas distributor (4) and the second gas distributor (6) work together. In this way, the bubbles formed can be thinned and the gas inside the reaction chamber (101) The distribution can be optimized. In addition, the diameter of the circulation pipe (2) reactor 25 Since it is smaller than the diameter of its body (1), the circulation tube (2), reaction materials to the central region of the reactor body (1) or near the central region It is arranged to transmit to the location. In addition, the reactor shell (1) The first material inlet channel (7) distributed along the circumferential direction into the reaction chamber (101) makes the incoming materials more uniform. In addition, the circulation pipe 30 (2) divides the reaction chamber (101) into different regions and the environment in the different regions is different It allows water to flow in the directions (as shown in Figure 5, circulation pipe (2)) The medium in the central region inside flows upwards and through the circulation pipe (2) (the medium in the surrounding annular flow region flows downwards), thus the reaction 16 It creates circulation of the medium within its reservoir (101). In addition, the circulation pipe (2) Multiple ventilation sections arranged on it, inside the reaction chamber (101) It can promote radial flow of the medium and mechanisms such as collision and shear. This allows for further refinement of the bubbles, thus improving the dispersion of the medium. It optimizes and improves reaction uniformity. 5 The above explanations are specific examples only, beyond the scope of the current statement. These are their configurations and are not intended to limit the scope of the current statement. Related by a person with expertise in the technical field, from the concepts and principles of the current explanation Any equivalent changes and modifications made without separation shall be in accordance with Article 10 of the current description. It is within the scope of protection.
