Description

Technical Field

[0001] This invention relates to the field of reaction vessel technology, and more specifically to a horizontal reaction vessel. Background Technology

[0002] Polyester blended fabric systems, such as polyester spandex, polyester cotton, polyester nylon, and polyester wool blends, involve adding a depolymerization solution to waste polyester blended fabrics during depolymerization. The solution is stirred and mixed with the fabric, causing the polyester fiber components to decompose and reduce to their original, powdery form: dimethyl terephthalate (DMT) and ethylene glycol. While the polyester components are depolymerized into DMT, the non-polyester fiber components in the blended fabric remain chemically stable and will not decompose under the same depolymerization conditions. They will remain in their original fibrous web form.

[0003] Currently, polyester blended fabrics are generally depolymerized using a reactor. During depolymerization, the polyester blended fabric is introduced into the reactor, and then a filter screen is installed at the outlet of the reactor. The filter screen intercepts the residual mesh material and discharges the depolymerization solution and DMT.

[0004] After depolymerization, the residual mesh material in the reactor adsorbs the depolymerization solvent and DMT, preventing effective discharge with the liquid and resulting in incomplete separation of the depolymerization solution, DMT, and mesh material. Furthermore, the residual non-polyester components in the reactor, after being squeezed, can significantly reduce the amount of solvent they adsorb, increasing drying efficiency while reducing energy consumption. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a horizontal reactor to solve the technical problem of incomplete separation of depolymerization solution, DMT and fabric in the reactor in the prior art.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: This invention provides a horizontal reaction vessel, comprising: The reaction assembly includes a horizontal vessel body and a sieve plate. The horizontal vessel body has a feed inlet, a slurry outlet, and a discharge outlet. The sieve plate is built into the horizontal vessel body and is arranged along the axial direction of the horizontal vessel body, dividing the internal cavity of the horizontal vessel body into a reaction chamber and a separation chamber. The reaction chamber is connected to the feed inlet and the discharge outlet, and the separation chamber is connected to the slurry outlet. A stirring assembly is connected to the horizontal vessel body, and the stirring end of the stirring assembly is rotatably integrated into the reaction chamber; and The separation assembly includes an extruder and a linear drive. The extruder is fitted and slidably integrated into the reaction chamber. The linear drive connects the extruder and the horizontal vessel body and is configured to drive the extruder to move axially along the horizontal vessel body.

[0007] In one embodiment, the stirring assembly includes a rotating shaft, a plurality of stirring elements, and a rotary drive. The rotating shaft is rotatably built into the reaction chamber. The plurality of stirring elements are spaced apart along the axial direction of the rotating shaft and are all connected to the rotating shaft. The rotary drive connects the rotating shaft and the horizontal vessel body and is configured to drive the rotating shaft to rotate.

[0008] In one embodiment, the stirring component includes a fixed sleeve and three blades. The fixed sleeve is fitted onto the rotating shaft, and the three blades are all connected to the rotating shaft and are spaced apart circumferentially along the rotating shaft. The included angle between adjacent blades is 120°, and the blades are spiral-shaped.

[0009] In one embodiment, the inner wall of the reaction chamber is formed with a protrusion, the protrusion being arranged along the axial direction of the horizontal vessel and connected to the inner wall of the horizontal vessel via an arc surface along the circumference of the horizontal vessel.

[0010] In one embodiment, the extruder is slidably fitted onto the protrusion.

[0011] In one embodiment, the extruder has an opening that matches the shape of the stirring end of the mixing assembly, so that the extruder can be slidably fitted onto the stirring end of the mixing assembly through the opening.

[0012] In one embodiment, the extruder has a plurality of filter holes, which are evenly distributed on the extruder and are arranged along the axial direction of the horizontal reactor body.

[0013] In one embodiment, the protrusion is provided with a cavity and a communicating groove connecting the cavity and the interior of the horizontal vessel body along the axial direction of the horizontal vessel body. The linear drive includes a lead screw, a nut, a connecting block, and a drive motor. One end of the lead screw is rotatably embedded in the cavity, and the other end is rotatably extended out of the horizontal vessel body. The nut is threadedly connected to the lead screw. One end of the connecting block is connected to the nut, and the other end passes through the communicating groove and is connected to the extrusion member. The drive motor is fixed to the end of the horizontal vessel body and connected to the other end of the lead screw.

[0014] In one embodiment, the shape of at least one side of the extruder matches the axial end face shape of the horizontal vessel body, so that one side of the extruder can fit against the inner end wall of the horizontal vessel body.

[0015] In one embodiment, the horizontal reactor further includes a drying component, the air outlet of which is connected to the reaction chamber and configured to introduce hot air into the reaction chamber, dry the material with the hot air, and discharge the dried material from the outlet.

[0016] Compared with the prior art, the horizontal reactor provided by the present invention, when depolymerizing waste polyester blended fabric, introduces the fabric into the horizontal reactor body through the feed port, adds a depolymerization solution to it, and after the depolymerization solution is introduced into the horizontal reactor body, the depolymerization solution and the polyester blended fabric are stirred and mixed in the horizontal reactor body. The polyester fiber component in the fabric is decomposed and reduced to the original, powdered dimethyl terephthalate (DMT) and ethylene glycol. While the polyester component is depolymerized into DMT, the non-polyester fiber component in the blended fabric remains chemically stable and will not be decomposed under the same depolymerization conditions. They will remain in the original fiber network form, forming a sheet-like framework structure.

[0017] The fabric and depolymerization solution are fed into the reaction chamber of the horizontal reactor body through the feed inlet. The stirring assembly is activated, and the stirring end of the assembly thoroughly mixes the fabric and depolymerization solution in the reaction chamber. The powdered DMT formed by depolymerization can pass through the sieve plate and enter the separation chamber, and is discharged from the slurry outlet of the separation chamber. After depolymerization is completed, in order to fully recover the DMT in the solution, the linear drive is activated. The linear drive drives the extruder to move, and the extruder squeezes the residual mesh material in the reaction chamber. The solution and DMT in the mesh material are squeezed out and discharged. The discharged solution and DMT pass through the sieve plate and enter the separation chamber, and are discharged from the horizontal reactor body. Then, the extruder is driven to reset, so that the extruder moves to fit the inner wall of the end of the horizontal reactor body, and then the residual mesh material in the horizontal reactor body is discharged from the discharge port.

[0018] By installing a sieve plate inside the horizontal reactor, the sieve plate can quickly discharge the depolymerized DMT into the reaction chamber, achieving rapid separation of DMT. At the same time, by installing an extruder, the extruder can drive the solution to separate from the mesh material when it extrudes the mesh material, and DMT follows the solution away from the mesh material, improving the recovery rate of DMT.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0022] To address the technical problem of incomplete separation of depolymerization solution, DMT, and fabric in a reactor, this invention provides a horizontal reactor capable of achieving thorough separation of depolymerization solution, DMT, and fabric.

[0023] Please see Figure 5 , Figure 5This is a cross-sectional view of a horizontal reactor according to an embodiment of the present invention. The horizontal reactor includes a reaction assembly 1, a stirring assembly 2, and a separation assembly 3. The reaction assembly 1 includes a horizontal reactor body 11 and a sieve plate 12. The horizontal reactor body 11 has a feed inlet 11a, a slurry outlet 11b, and a discharge outlet 11c. The sieve plate 12 is built into the horizontal reactor body 11 and arranged along the axial direction of the horizontal reactor body 11, dividing the internal cavity of the horizontal reactor body 11 into a reaction chamber 11d and a separation chamber 11e. The reaction chamber 11d is connected to the feed inlet 11a and the slurry outlet 11b. The feed inlet 11a and the discharge outlet 11c are connected, and the separation chamber 11e is connected to the slurry outlet 11b; the stirring assembly 2 is connected to the horizontal vessel body 11, and the stirring end of the stirring assembly 2 is rotatably built into the reaction chamber 11d; the separation assembly 3 includes an extruder 31 and a linear drive 32, the extruder 31 is fitted and slidably built into the reaction chamber 11d, and the linear drive 32 is connected to the extruder 31 and the horizontal vessel body 11, configured to drive the extruder 31 to move axially along the horizontal vessel body 11.

[0024] Specifically, when depolymerizing waste polyester blended fabric, the fabric is introduced into the horizontal reactor 11 through the feed inlet 11a, and a depolymerization solution is added to it. After the depolymerization solution is introduced into the horizontal reactor 11, it is stirred and mixed with the polyester blended fabric. The polyester fiber component in the fabric is decomposed and reduced to the original, powdered dimethyl terephthalate (DMT) and ethylene glycol. While the polyester component is depolymerized into DMT, the non-polyester fiber component in the blended fabric remains chemically stable and will not be decomposed under the same depolymerization conditions. They will remain in their original fiber network form, forming a sheet-like framework structure.

[0025] The fabric and depolymerization solution are fed into the reaction chamber 11d of the horizontal reactor body 11 through the feed inlet 11a. The stirring assembly 2 is activated, and the stirring end of the stirring assembly 2 thoroughly mixes the fabric and depolymerization solution in the reaction chamber 11d. The powdered DMT formed by depolymerization can pass through the sieve plate 12 and enter the separation chamber 11e, and is discharged from the slurry outlet 11b of the separation chamber 11e. After depolymerization is completed, in order to fully recover the DMT in the solution, the linear drive 32 is activated. The linear drive 32 drives the extruder 31 to move, and the extruder 31 extrudes the reaction chamber 11d. The residual mesh material in 1d is squeezed out by the solution in the mesh material. DMT is separated from the mesh material along with the solution. The discharged solution and DMT pass through the sieve plate 12 into the separation chamber 11e and are discharged from the horizontal vessel 11 from the separation chamber 11e. After the solution and DMT are separated from the mesh material, the solution content in the mesh material is reduced, which facilitates drying. Then, the extruder 31 is driven to reset, so that the extruder 31 moves to fit the inner wall of the end of the horizontal vessel 11. Then, the residual mesh material in the horizontal vessel 11 is discharged from the outlet 11c.

[0026] By setting a sieve plate 12 inside the horizontal reactor body 11, the sieve plate 12 can quickly discharge the depolymerized DMT into the reaction chamber 11d, thus achieving rapid separation of DMT. At the same time, by setting an extruder 31, when the extruder 31 extrudes the mesh material, it can drive the solution to separate from the mesh material, and DMT follows the solution away from the mesh material, thereby improving the recovery rate of DMT.

[0027] It should be understood that the discharge port 11c can be located at both ends or in the middle of the horizontal vessel body 11. The bottom of the horizontal vessel body 11 gradually decreases in height along the direction close to the discharge port 11c, so that the solution DMT can approach the discharge port 11c by gravity and be discharged from the discharge port 11c.

[0028] It should be understood that the stirring component 2 can be a stirring paddle driven by an electric motor, or a stirring paddle driven by a hydraulic motor, magnetic force, or other means.

[0029] like Figure 3 As shown, in one embodiment, the stirring assembly 2 includes a rotating shaft 21, a plurality of stirring elements 22, and a rotary drive 23. The rotating shaft 21 is rotatably built into the reaction chamber 11d. The plurality of stirring elements 22 are spaced apart along the axial direction of the rotating shaft 21 and are all connected to the rotating shaft 21. The rotary drive 23 is connected to the rotating shaft 21 and the horizontal vessel body 11 and is configured to drive the rotating shaft 21 to rotate.

[0030] When it is necessary to stir the material and depolymerization solution, the rotary drive 23 is activated, which drives the rotating shaft 21 to rotate. The rotating shaft 21 drives multiple stirring elements 22 to rotate. The multiple stirring elements 22 stir the material and depolymerization solution in the horizontal reactor 11, avoiding the formation of dead zones in the stirring, ensuring the uniformity of the concentration and temperature of the reactants, and improving the reaction efficiency.

[0031] It should be understood that the number of stirring components 22 can be one, two, three, four, or five, etc. Specifically, in one embodiment, the number of stirring components 22 is preferably three, and the three stirring components 22 are arranged parallel to each other and spaced apart.

[0032] The agitator 22 can be a single blade, an inclined straight blade, etc., specifically, such as Figure 3 As shown, in one embodiment, the stirring element 22 includes three blades 221, each connected to a rotating shaft 21 and spaced apart circumferentially along the shaft 21. The included angle between adjacent blades 221 is 120°, and the blades 221 are helical. The included angle between the blades 221 and the axis of the rotating shaft 21 is 5° to 10°. It should be understood that the blades can be directly welded to the central shaft or fixed to the central shaft by bolts.

[0033] When the spiral blades 221 rotate, they not only generate radial mixing but also axial pushing force, which promotes the material to move along the axial direction of the horizontal vessel body 11, enhancing the mixing effect of the material and preventing local accumulation of material. At the same time, it reduces the contact area and time between the blades 221 and the material, reduces the bearing load, and lowers the risk of entanglement. It is suitable for processing fibrous materials that are easy to entangle and clump together, effectively breaking up the material and preventing it from entangled on the blades 221. The rotating shaft 21 and the blades 221 can operate in reverse intermittently / at low speed. By setting the angle between the axis of the blades 221 and the axis of the rotating shaft 21 to 5°-10°, if the angle is too small, the axial pushing force will be weak; if the angle is too large, the stirring resistance will increase sharply and the energy consumption will increase. The angle range of 5°-10° ensures effective axial mixing while reducing energy consumption.

[0034] To reduce fabric adhesion to the blades 221, in one embodiment, the surface of the blades 221 is polished.

[0035] Polishing the surface of blade 221 can improve the smoothness of the blade 221 surface and reduce the adhesion of materials to blade 221.

[0036] It should be understood that if the distance between the impeller 221 and the sieve plate 12 is too far, the impeller 221 may not be able to stir the solution on the sieve plate 12, leading to DMT precipitation and potentially clogging the sieve holes of the sieve plate 12. Therefore, in one embodiment, the distance between the sieve plate 12 and the impeller 221 is 1-6 cm. This avoids the impeller 221 being unable to stir the solution on the sieve plate 12 due to excessive distance, thus preventing DMT precipitation and clogging of the sieve plate 12.

[0037] To ensure thorough mixing of the fabric and the depolymerization solution within the horizontal reactor 11, therefore, as follows: Figure 3 , Figure 6 and Figure 7 As shown, in one embodiment, the inner wall of the reaction chamber 11d is formed with a protrusion 13, which is arranged along the axial direction of the horizontal vessel body 11 and is connected to the inner wall of the horizontal vessel body 11 via an arc surface along the circumference of the horizontal vessel body 11.

[0038] When the rotating shaft 21 drives the blade 221 to rotate, it stirs the material and solution inside the horizontal vessel 11. When the material comes into contact with the protrusion 13, the protrusion 13 will change the direction of material movement, prevent material accumulation, and make the material fully dispersed and fully deagglomerated.

[0039] While ensuring sufficient dispersion of the material, in one embodiment, the protrusion 13 is specifically designed to allow the extrusion member 31 to be slidably fitted onto the protrusion 13.

[0040] The protrusion 13 slides with the extruder 31, providing precise linear guidance for the reciprocating motion of the extruder 31, ensuring that it does not deflect, shake or jam during movement, thereby ensuring the stability of the extrusion action.

[0041] It should be understood that the linear drive component 32 can be a hydraulic cylinder, a pneumatic cylinder, or an electric actuator, etc. Specifically, for example... Figure 1 , 2 As shown in Figures 6 and 7, in one embodiment, the protrusion 13 is provided with a cavity and a communicating groove connecting the cavity and the interior of the horizontal vessel body 11 along the axial direction of the horizontal vessel body 11. The linear drive component 32 includes a lead screw 321, a nut 322, a connecting block 323, and a drive motor 324. One end of the lead screw 321 is rotatably embedded in the cavity, and the other end is rotatably extended out of the horizontal vessel body 1. The nut 322 is threadedly connected to the lead screw 321. One end of the connecting block 323 is connected to the nut 322, and the other end passes through the communicating groove and is connected to the extrusion component 22. The drive motor 324 is fixed to the end of the horizontal vessel body 11 and connected to the other end of the lead screw 321, configured to drive the lead screw 321 to rotate.

[0042] When the extruder 22 needs to be moved, the drive motor 324 is activated, which drives the lead screw 321 to rotate. The rotating lead screw 321 pushes the connecting block 323 and the extruder 31 to move axially along the horizontal reactor body. The linear drive mechanism, including the lead screw 321, nut 322, and connecting block 323, is completely integrated and hidden inside the guide protrusion. The rotating lead screw 321 and the moving nut 322 are placed in a cavity relatively isolated from the reaction chamber and connected to the reaction chamber through a narrow connecting groove. This protects the lead screw 321 and nut 322 from the intrusion of materials, liquids, or vapors in the reaction chamber, preventing corrosion or jamming of the precision transmission components. At the same time, the absence of a complex drive mechanism inside the reaction chamber makes it easier to clean.

[0043] When the extruder 31 is extruding the material in the reaction chamber 11d, when the extruder 31 approaches the blade 221, the blade 221 will hinder the continued movement of the extruder 31. Therefore, as Figure 3As shown, in one embodiment, the extruder 31 has an opening 31a that matches the shape of the stirring end of the mixing assembly 2, so that the extruder 31 can slide onto the stirring end of the mixing assembly 2 through the opening 31a. It should be understood that the blades 221 in the plurality of mixing components 22 can be coaxially arranged so that when the blades 221 in the plurality of mixing components 22 stop rotating, they are directly opposite the opening 31a of the extruder 31. Alternatively, the blades 221 in the plurality of mixing components 22 can be arranged at intervals along the circumference of the rotating shaft 21. During the extrusion process of the extruder 31, when the extruder 31 moves to the corresponding blade 221, the rotating shaft 21 and the blade 221 are controlled to rotate, so that the opening 31a of the extruder 31 is positioned relative to the blade 221, allowing the extruder 31 to slide onto and pass over the blade 221 through the opening 31a. When the extruder 31 has not reached a specific position, the mixing paddle can still rotate at a low speed, driving the material to rotate, so that the material is uniformly extruded.

[0044] In this embodiment, by providing an opening 31a on the extruder 31 that matches the blade 221, when it is necessary to extrude the fabric, the opening 31a of the extruder 31 is positioned relative to the blade 221 of the agitator 22. The extruder 31 begins to extrude the fabric in the reaction chamber 11d. When the extruder 31 passes the blade 221, the extruder 31 can be fitted onto the blade 221 through the opening 31a and slide past the blade 221, so that the extruder 31 can fully extrude the fabric in the reaction chamber 11d. Since the size of the fabric remaining in the reaction chamber 11d is relatively large, it is not easy to pass through the opening 31a, and the blade 221 blocks the opening 31a, which can prevent the fabric from passing through the opening 31a.

[0045] In order to ensure that the opening 31a of the extruder 31 is directly opposite the blade 221 of the agitator 22 when the blade 221 stops rotating, in one embodiment, the rotary drive 23 can be a servo motor, or a positioning locking mechanism can be provided between the rotary drive 23 and the agitator shaft.

[0046] The servo motor has precise position control capabilities, allowing the setting of the absolute angle at which the stirring shaft stops. This ensures that the orientation of all blades 221 is perfectly aligned with the opening 31a on the extruder 31, then stops and locks in that position. This allows the extruder 31 to precisely pass through the aligned blades 221 via the opening 31a.

[0047] When discharging the fabric from the horizontal vessel 11, heated gas needs to be introduced into the horizontal vessel 11. In order to prevent the heated gas from carrying the fabric through the opening 31a into the gap between the extruder 31 and the horizontal vessel 11, in one embodiment, the shape of at least one side of the extruder 31 matches the shape of the end face of the horizontal vessel 11 along the axial direction, so that one side of the extruder 31 can fit against the inner wall of the end of the horizontal vessel 11.

[0048] During the drying and discharge of the fabric, the extruder 31 is reset so that it fits against the inner wall of one end of the horizontal reactor body 11. At this time, the extruder 31 fits against the inner wall of the end of the horizontal reactor body 11, forming an effective physical seal, which can prevent the fabric from entering between the extruder 31 and the horizontal reactor body 11 during the heating and discharge process.

[0049] During the extrusion process of the fabric, if the extruder 31 is a plate, the solution extruded from the fabric can only flow out of the reaction chamber 11d through the sieve plate 12, which will cause significant resistance to the extrusion process of the extruder 31, and the sieve plate 12 will bear a large extrusion force. Therefore, if... Figure 3 As shown, in one embodiment, the extruder 31 has a plurality of filter holes 31b, which are evenly distributed on the extruder 31 and are arranged along the axial direction of the horizontal reactor body 11.

[0050] When the extruder 31 extrudes the fabric, because the extruder 31 has filter holes 31b, the solution is squeezed out of the fabric when it is squeezed. The solution can enter the separation chamber 11e through the sieve plate 12, and can also pass through the filter holes 31b of the extruder 31. After passing through the extruder 31, it enters the separation chamber 11e from the sieve plate 12. The solution has many nearby outlets during the extrusion process, and its forward flow resistance is greatly reduced, which reduces the extrusion pressure on the sieve plate 12. The solution in the fabric can be separated from multiple directions, reducing the flow path of the solution when it leaves the fabric, and making it easier for the solution to leave the fabric.

[0051] In order to dry the reacted fabric and control its detachment from the horizontal reactor, for this purpose, such as Figure 1 and Figure 4 As shown, in one embodiment, the horizontal reactor further includes a drying component 4. The air outlet of the drying component 4 is connected to the reaction chamber 11d and is configured to introduce hot air into the reaction chamber 11d, and dry the material by means of the hot air, and drive the dried material out from the discharge port 11c.

[0052] This embodiment integrates hot air drying and pneumatic conveying functions directly into the reactor body. The hot air, while drying the material, also directly uses its flow momentum to discharge the material from the equipment. This eliminates intermediate transfer and loading / unloading steps, shortens the overall processing time, improves production efficiency, and reduces potential losses and contamination caused by material transfer. Fabrics after depolymerization and dehydration are typically lightweight and fluffy, easily sticking and piling up. Traditional mechanical discharge methods (such as screw conveyors) may suffer from poor discharge, bridging, or fiber entanglement. This embodiment uses pneumatic conveying for discharge, utilizing the kinetic energy of hot air to directly and gently blow the dried fibers out from the discharge port 11c. This is suitable for processing such lightweight, easily entangled fibrous materials and minimizes mechanical damage to the fiber structure.

[0053] It should be understood that the drying component 4 can be a fan capable of heating nitrogen, a pipeline that provides hot nitrogen within the factory, or a hot air generator, etc.
