Description

Technical Field

[0001] The invention relates to the technical field of reactor separation devices, and in particular to a separation mechanism and a reactor with the mechanism. Background Art

[0002] The distillation reactor is a device used for the distillation process, commonly used in the chemical, pharmaceutical and food industries. It combines the functions of reaction and distillation, and can simultaneously separate and purify products during the reaction process. The function of the distillation reactor is to vaporize the liquid to be distilled and provide the necessary amount of rising steam in the tower. The types of distillations include jacketed, coiled tube and shell-and-tube types. Jacketed and coiled tube types are mostly used in small-scale production due to their smaller heating area, while shell-and-tube distillations are mostly used in large-scale production.

[0003] The steam of the existing distillation reactor needs to be liquefied through an external condenser. When the steam flow is too large or dirt accumulates on the internal surface of the condenser, the condenser will not condense completely. At the same time, if there are solid impurities or undissolved solids in the reactants, the steam formed by the reactants will carry these solid particles, resulting in insufficient purity of the extracted material. Therefore, the present application provides a separation mechanism and a reactor with the mechanism to meet the needs. Summary of the invention

At the same time, it can prevent the solid particles from sticking to the inner wall of the pretreatment structure 4, causing the inner wall of the pretreatment structure 4 to be blocked or accumulate dirt for a long time, affecting the heat exchange effect, and causing the condensation efficiency to decrease; the separation structure 5 includes a separation unit 52 connected to the bottom of the separation shell 51, and the separation unit 52 is connected to a secondary separation component 53; the pretreatment structure 4 is located at the top of the separation shell 51, and the pretreatment structure 4 is connected to the separation shell 51, and the pretreatment structure 4 is used to condense and pretreat the material steam separated by the separation structure 5, which greatly relieves the condensation pressure of the external condenser and avoids the situation where the steam is not completely condensed during the distillation process.

[0048] During operation, the distillation raw materials are discharged into the lower kettle body 1 from the raw material inlet at the top of the upper kettle body 2, and then the lower kettle body 1 is heated. The various raw materials are stirred and mixed by the second stirring blade 32 and the third stirring blade 33. By utilizing the principle of different boiling points of different raw materials, the material with a lower boiling point in the lower kettle body 1 forms steam, which is driven by the first stirring blade 31 and enters the separation structure 5 for separation of solid particles. The steam separated by the separation structure 5 enters the pretreatment structure 4 for pretreatment.

[0049] like Figures 2 to 6 and Figure 8 As shown, the interior of the separation shell 51 is hollow, and the separation shell 51 with a hollow interior provides installation space for the separation unit 52 and the secondary separation component 53. One end of the separation shell 51 is provided with an outward-turned installation port 512 that penetrates the interior thereof, and an outward-turned ring piece 511 is fixedly connected to the outward-turned installation port 512.

The two side surfaces of the diverter plate 522 are fixedly connected with a plurality of protrusions with uniform spacing. The protrusions are used to guide the passing steam so that it flows in a wave-like manner in the channel between every two diverter plates 522, thereby increasing the contact with the primary separation unit 6. The protrusions on the opposite surfaces of every two diverter plates 522 are staggered with each other. A separation mounting groove 5221 is provided on the surface of the diverter plate 522 near every two adjacent protrusions. The separation mounting groove 5221 is used to provide an installation position for the primary separation unit 6. The primary separation unit 6 is connected to the separation mounting groove 5221. The primary separation unit 6 is used to initially separate solid particles passing through the steam. A secondary separation component 53 is connected to the side of the bottom plate 521 near the guide outlet 513. The secondary separation component 53 is used to further separate solid particles passing through the steam.

[0051] When the distilled steam enters the separation shell 51 through the outward-turned ring sheet 511, the steam is intercepted by the partition 523, so that it moves in the direction of the air guide module. The steam in the flow process flows in a wave shape in the channel between every two diverter plates 522 under the guidance of the protrusions. During the flow, it contacts the primary separation unit 6 for initial separation. After the initial separation, the steam flows to the secondary separation component 53 for further separation, until it flows from the outlet 513 to the pretreatment structure 4 after separation.

Every two diverter plates 522 are sealed near the top of the fan-shaped groove 5316, so that the steam can only enter the square groove 5317. The steam flowing out from the channel between the diverter plates 522 enters the secondary separation unit 532 in the square groove 5317 at the first time, and after separation by the secondary separation unit 532, it flows along the arc surface of the fan-shaped groove 5316 to the guide outlet 513.

The two ends of the connecting section 453 are fixedly connected to the second guide section 452 and the surface-increasing section 454 respectively, and the other ends of the second guide section 452 and the surface-increasing section 454 are both fixedly connected to the inner wall of the pre-condensing tube 41; the first-level guide plate 46 and the second guide plate 45 are both provided with a plurality of guide grooves 451 distributed in an annular shape on the opposing surfaces.

[0056] The steam enters the pre-condensing tube 41 from the inlet pipe 42, and first contacts the first guide section 461. The steam is guided by the arc surface of the first guide section 461, and is directed from the air outlet to the surface of the second guide section 452, so that the steam flows from the outside to the inside of the surface of the second guide section 452. Since the second guide section 452 is in contact with the outside and the surface temperature of the second guide section 452 is low under the operation of external blowing, the steam condenses into liquid by contacting the surface of the second guide section 452, and flows along the guide groove 451 to the bottom of the inner wall of the pre-condensing tube 41. The temperature of the uncondensed steam will decrease, and under the guidance of the second guide section 452, it will flow back to the outer surface of the first guide section 461, and under the guidance of the anti-backflow section 462, it will flow to the air outlet of the second guide section 452, and then enter the tail pipe 44 along the pre-condensing tube 41, and finally flow to the outlet pipe 43.

[0057] The present invention also provides a technical solution: a reaction kettle, such as Figures 1 to 16 As shown, it includes a lower kettle body 1, an upper kettle body 2 and a driving device 3, the top of the lower kettle body 1 is fixedly connected to the upper kettle body 2, the top of the upper kettle body 2 is fixedly connected to the driving device 3, the output end of the driving device 3 passes through the upper kettle body 2 and extends to the interior of the lower kettle body 1, the output end of the driving device 3 is fixedly connected to the first stirring blade 31, the second stirring blade 32 and the third stirring blade 33 in sequence, the separation shell 51 is fixedly connected to the inner surface wall of the upper kettle body 2, one side and the top of the separation shell 51 are adapted to the inner surface wall and the top of the upper kettle body 2, an inlet hole is opened on the upper kettle body 2, and the outer wall of the inlet pipe 42 is fixedly connected to the inner wall of the inlet hole.

[0058] The lower kettle body 1 has an upper kettle body 2 fixedly connected to the top of the lower kettle body 1, and a driving device 3 fixedly connected to the top of the upper kettle body 2. The output end of the driving device 3 passes through the upper kettle body 2 and extends to the interior of the lower kettle body 1. The upper kettle body 2, the lower kettle body 1 and the driving device 3 are prior art. The output end of the driving device 3 is fixedly connected with a first stirring blade 31, a second stirring blade 32 and a third stirring blade 33 in sequence. The third stirring blade 33 is arranged in parallel with the vertical direction of the output end. The mixed material at the bottom of the lower kettle body 1 is driven to stir by the third stirring blade 33, so that the mixed material is stirred more evenly. The second stirring blade 32 is arranged at an angle of 30° to the vertical direction of the output end, and is used to drive the mixed material at the top of the lower kettle body 1 to move to the bottom of the lower kettle body 1 during the stirring process. The deflection angle of the first stirring blade 31 is opposite to that of the second stirring blade 32, and is used to drive the steam evaporated by heating the lower kettle body 1 toward the upper kettle body 2, so that the steam quickly enters the separation structure 5.

[0059] The working principle of the technical solution provided by the present invention is as follows: when working, the distillation raw materials are discharged into the lower kettle body 1 from the raw material inlet at the top of the upper kettle body 2, and then the lower kettle body 1 is heated, and the various raw materials are stirred and mixed by the second stirring blade 32 and the third stirring blade 33. By utilizing the principle that different raw materials have different boiling points, the material with a lower boiling point in the lower kettle body 1 forms steam, and enters the separation structure 5 driven by the first stirring blade 31 to separate the solid particles.

[0060] When the distilled steam enters the separation shell 51 through the outward-turned ring sheet 511, the steam is intercepted by the partition 523, so that the steam moves in the direction of the wind guide module. The steam in the flow process flows in a wave shape in the channel between every two diverter plates 522 under the guidance of the protrusion. During the flow, it contacts the primary separation unit 6 for initial separation. The steam passes through the column 62 to intercept the steam and slow it down. The steam can fully contact the surface of the plush pad 63 to intercept the solid particles in the steam. The steam passing through the channel between the diverter plates 522 enters the square groove 5317 through the secondary separation plate 5321. When passing through the secondary separation plate 5321, the steam enters the collecting ring 541 from the separation hole 5323, and then enters the stop pipe 543 along the collecting bend 542 connected to the collecting ring 541, until it enters the square groove 5317. After separation by the secondary separation unit 532, it flows toward the outlet 513 along the arc surface of the fan-shaped groove 5316.

[0061] The steam enters the pre-condensing tube 41 from the inlet pipe 42, and first contacts the first guide section 461. The steam is guided by the arc surface of the first guide section 461, and is directed from the air outlet to the surface of the second guide section 452, so that the steam flows from the outside to the inside of the surface of the second guide section 452. Since the second guide section 452 is in contact with the outside and the surface temperature of the second guide section 452 is low under the operation of external blowing, the steam condenses into liquid by contacting the surface of the second guide section 452, and flows along the guide groove 451 to the bottom of the inner wall of the pre-condensing tube 41. The temperature of the uncondensed steam will decrease, and under the guidance of the second guide section 452, it will flow back to the outer surface of the first guide section 461, and under the guidance of the anti-backflow section 462, it will flow to the air outlet of the second guide section 452, and then enter the tail pipe 44 along the pre-condensing tube 41, and finally flow to the outlet pipe 43.
