However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0048] This embodiment provides a treatment reaction device suitable for the technical field of biomass dilute acid pretreatment. Figure 1 As shown, the treatment reaction device includes a reactor 1, and the reactor 1 is provided with a feed port 101, and the feed port 101 is used to pass the material to be treated. Among them, the material can be specifically selected from biomass straw, the material particle size is about 5cm to 100cm, the material length is about 40cm to 70cm, and the solid-liquid ratio can be selected to be about 1:2. Add the solvent required for pretreatment to the reactor 1, for example: 10kg of 1% hydrochloric acid. The solid-liquid ratio of the material to the solvent can be selected to be about 1:2, then the treatment reaction device can also be called a biomass dilute acid pretreatment reactor.

[0049] The reactor 1 is specifically a rectangular or cylindrical structure, the shell of the reactor 1 is made of stainless steel and glass-lined, the pretreatment pressure can reach 0.1MPa to 0.6MPa, and the internal material of the reactor 1 can be made of high temperature, high pressure and corrosion resistant materials, such as polytetrafluoroethylene.

[0050] Among them, the feed port 101 can be set at at least one end of the reactor 1 along the axial direction of the reactor 1, for example, the front end and / or the rear end of the reactor 1; of course, in some other embodiments, the feed port 101 can also be set in the middle position of the reactor 1.

[0051] like Figure 1As shown, the reactor 1 further includes a material guide structure 6, which is at least partially disposed in the reactor 1, and a feed port 101 is disposed at one end of the material guide structure 6 away from the reactor 1. The material guide structure 6 plays a role in guiding the material transportation, and the material introduced from the feed port 101 is conveniently transported to the reactor 1 under the guidance of the material guide structure 6. The material guide structure 6 can be specifically a material guide pipe, which is convenient for sequentially adding the material into the reactor 1. A control valve can be provided on the material guide pipe to control the feeding speed of the material.

[0052] The reactor 1 of the existing treatment reaction device is provided with a stirring structure, which is used to stir the materials so that the materials can fully react in the reactor 1. However, during the high-speed rotation of the stirring structure in the reactor 1, part of the materials may be squeezed between the anti-blocking stirring structure and the inner wall of the reactor 1, causing the anti-blocking stirring structure to be stuck and unable to rotate.

[0053] To solve this problem, Figure 1 As shown, the processing reaction device provided in this embodiment includes an anti-blocking stirring structure 2, which is arranged in the reactor 1 and can rotate relative to the reactor 1. A accommodating chamber 20 is arranged in the anti-blocking stirring structure 2, and the accommodating chamber 20 is used to accommodate materials.

[0054] The processing reaction device provided in this embodiment can rotate relative to the reactor 1 by using the anti-blocking stirring structure 2 to achieve full contact and mixing of materials. The accommodating chamber 20 of the anti-blocking stirring structure 2 provides a accommodating space for the material, and the material can be confined to the inside of the accommodating chamber 20. When the anti-blocking stirring structure 2 rotates relative to the reactor 1, the material will not be blocked between the reactor 1 and the anti-blocking stirring structure 2, avoiding the risk of the anti-blocking stirring structure 2 getting stuck, so as to ensure the smooth rotation of the anti-blocking stirring structure 2.

[0055] In one embodiment, Figure 1 As shown, the reactor 1 is provided with a steam inlet 103 and a steam outlet 104 .

[0056] The steam inlet 103 is used to introduce steam, and the steam outlet 104 is used to discharge steam. After the materials are evenly mixed, they are heated by steam so that the temperature and pressure in the reactor 1 reach the set values. For example, the temperature in the reactor 1 is about 150° C., and the reaction time is about 1 hour, which can increase the reaction speed and effect of the materials. The steam discharged through the steam outlet 104 can be used for heat utilization in other links, making full use of thermal energy, reducing energy consumption, and reducing overall costs.

[0057] In one embodiment, the anti-blocking stirring structure 2 includes a containing tube 201 , the containing tube 201 is provided with a through hole 202 , the containing chamber 20 is provided in the containing tube 201 , and the containing chamber 20 is communicated with the through hole 202 .

[0058] The through holes may be circular holes, strip holes, etc. The through holes are used to connect the accommodating chamber 20 with the inner cavity of the reactor 1, so that the steam is in full contact with the material, thereby improving the mass transfer effect and the stirring uniformity.

[0059] In one embodiment, the anti-blocking stirring structure 2 further includes a reinforcing rod 23 , which is disposed in the containing cylinder 201 to strengthen the containing cylinder 201 and increase the structural strength of the containing cylinder 201 .

[0060] The existing stirring structure is generally a spiral structure. When the material is a relatively long material such as straw, if the spiral structure stirs the material, the spiral structure will guide the material, making it easy for the material to be entangled in the spiral grooves of the spiral structure, causing the stirring structure to become stuck.

[0061] For this reason, Figure 2 As shown, the anti-blocking stirring structure 2 provided in this embodiment includes a plurality of stirring rods, the stirring rods are linear structures, and the plurality of stirring rods are interconnected to form a frame structure.

[0062] The anti-blocking stirring structure 2 provided in this embodiment has a plurality of stirring rods connected to each other to form a frame structure, which can also be referred to as a cage-shaped structure having a receiving cavity 20. Compared with the existing spiral structure, since each stirring rod is a linear structure, the material will not be fed or guided all the time, the risk of the material being entangled in the stirring rod is reduced, and the anti-blocking stirring structure 2 itself is prevented from being stuck and locked, resulting in difficulty in rotation.

[0063] The frame structure is provided with an open end, which is arranged corresponding to the feed port 101 and is connected to each other, and the material added from the feed port 101 enters the accommodating cavity 20 of the frame structure through the open end. At the same time, the frame structure is not a closed structure, that is, there may be a gap between two adjacent stirring rods, so that the material can fully contact with the air or steam in the reactor 1.

[0064] Specifically, Figure 2 As shown, the stirring rod includes a first stirring rod 21 and a second stirring rod 22, the first stirring rod 21 is connected to the second stirring rod 22, and the first stirring rod 21 and the second stirring rod 22 are arranged at an angle. That is, the first stirring rod 21 and the second stirring rod 22 are at least arranged crosswise, and the two stirring rods are staggered and overlapped, thereby increasing the structural stability of the anti-blocking stirring structure 2.

[0065] For example, the number of the first stirring rod 21 and the number of the second stirring rod 22 are both multiple, and multiple first stirring rods 21 and multiple second stirring rods 22 can form a relatively stable frame structure. Of course, the number of the first stirring rod 21 and the second stirring rod 22 can be the same or different, and the specific number is not limited in this embodiment and can be adjusted according to actual production needs.

[0066] Exemplarily, the angle between the first stirring rod 21 and the second stirring rod 22 may be an acute angle, a right angle, or an obtuse angle. The present embodiment does not limit the angle between the two stirring rods, and the angle may be adjusted according to actual production needs.

[0067] It can be understood that the anti-blocking stirring structure includes but is not limited to the first stirring rod 21 and the second stirring rod 22, and the anti-blocking stirring structure may also include other types of stirring rods.

[0068] In one embodiment, Figure 2 As shown, one of the first stirring rod 21 and the second stirring rod 22 is arranged parallel to the axial direction of the reactor 1 , and the other is arranged perpendicular to the axial direction of the reactor 1 .

[0069] For example, the first stirring rod 21 is arranged parallel to the axial direction of the reactor 1, and the second stirring rod 22 is arranged perpendicularly to the axial direction of the reactor 1, that is, the two stirring rods are arranged perpendicularly to each other. The arrangement order of the two stirring rods is not messy, but conforms to the setting direction of the reactor 1. The appearance is neat and easy to install.

[0070] In one embodiment, the anti-blocking stirring structure 2 also includes a reinforcing structure, which is arranged on the frame structure to increase the overall structural stability of the anti-blocking stirring structure 2.

[0071] Specifically, the reinforcement structure includes a reinforcement rod 23, which is disposed between the two first stirring rods 21 to improve the stability and fixing effect between the two first stirring rods 21. The reinforcement rod 23 can be disposed at an angle with the first stirring rod 21, for example, the reinforcement rod 23 can be disposed perpendicular to the first stirring rod 21, and the reinforcement rod 23 can be specifically disposed between two adjacent first stirring rods 21, or between two first stirring rods 21 disposed opposite to each other, and of course, can also be disposed between any two first stirring rods 21.

[0072] Exemplarily, the reinforcing rod 23 can also be arranged between the two second stirring rods 22 to improve the stability and fixing effect between the two second stirring rods 22; the reinforcing rod 23 can be arranged at an angle with the second stirring rod 22, for example, the reinforcing rod 23 can be arranged perpendicular to the second stirring rod 22, the reinforcing rod 23 can be specifically arranged between two adjacent second stirring rods 22, or between two oppositely arranged second stirring rods 22, and of course, can also be arranged between any two second stirring rods 22.

[0073] Exemplarily, the reinforcing rod 23 is arranged between the first stirring rod 21 and the second stirring rod 22 to improve the stability and fixing effect between the first stirring rod 21 and the second stirring rod 22. For example, the reinforcing rod 23 and the first stirring rod 21 and the second stirring rod 22 are all inclined. The reinforcing rod 23 can also be called an angled support, that is, the first stirring rod 21, the second stirring rod 22 and the reinforcing rod 23 are in a triangular structure. The triangular structure is used to stabilize the structure and further improve the structural stability of the anti-blocking stirring structure 2.

[0074] The axial direction of the reactor 1 is arranged parallel to the horizontal plane, that is, the processing reaction device is a horizontal structure. Therefore, it is difficult for the material added from the feed port 101 to directly enter the containing cavity 20 of the anti-blocking stirring structure 2.

[0075] To solve this problem, Figure 1-2 As shown, the treatment reaction device also includes a guide structure 3, which is arranged on the anti-blocking stirring structure 2 and is used to guide the material into the reactor 1 along a direction away from the feed inlet 101.

[0076] Even if the reactor 1 is a horizontal structure, the guide structure 3 can be used to guide the material from the feed port 101 to the accommodating chamber 20 of the reactor 1, thereby improving the mixing uniformity of the material in the reactor 1. At the same time, by setting the guide structure 3 on the anti-blocking stirring structure 2, when the anti-blocking stirring structure 2 rotates, the guide structure 3 can move with the rotation of the anti-blocking stirring structure 2, thereby realizing the process of guiding the material to feed, without adding an additional driving device to the guide structure 3, which is easy to use and reduces production costs.

[0077] Exemplarily, the guide structure 3 includes a guide plate, and the guide plate is a spiral structure.

[0078] Since the guide blade is arranged on the anti-blocking stirring structure 2, when the guide blade rotates with the anti-blocking stirring structure 2, the spiral groove of the guide blade guides the material, so that the material moves along the axial direction of the reactor 1, thereby improving the guiding and conveying effect of the material.

[0079] In one embodiment, there are multiple guide blades, and the multiple guide blades are arranged in parallel and at intervals along the axial direction of the reactor 1 , so that the material can be continuously fed and transported along the axial direction of the reactor 1 .

[0080] In one embodiment, there are multiple guide blades, which are arranged in parallel and spaced apart along the circumferential direction of the reactor 1, that is, the guide blades are equivalent to the extended parts of the inner wall of the anti-blocking stirring structure 2, which increases the contact area with the material and improves the uniformity of stirring.

[0081] It can be understood that multiple guide plates can be arranged along the axial and circumferential directions of the reactor 1 at the same time. For example, each circle of the reactor 1 has multiple guide plates, and the guide plates of each circle are arranged along the axial direction of the reactor 1; alternatively, multiple guide plates are arranged along the inner wall of the accommodating chamber 20 along a spiral structure.

[0082] If the multiple guide plates of the guide structure 3 are continuous spiral structures, when the guide structure 3 rotates with the anti-blocking stirring structure 2, the material is easily entangled on the guide plates, thereby causing the anti-blocking stirring structure 2 to become stuck, affecting the reliability of use.

[0083] To solve this problem, Figure 1-Figure 2 As shown, the projections of the plurality of guide plates relative to the reference plane do not overlap; wherein the reference plane is arranged parallel to the axial direction of the reactor 1; and / or, the reference plane is arranged perpendicular to the axial direction of the reactor 1.

[0084] When the reference plane is perpendicular to the axial direction of the reactor 1, the reference plane is the plane where the radial cross section of the reactor 1 is located, and the projections of the multiple guide plates relative to the reference plane do not overlap, that is, a first gap is provided between two adjacent guide plates along the radial direction, and the material can directly enter the bottom of the accommodating chamber 20 through the first gap.

[0085] When the reference plane is parallel to the axial direction of the reactor 1, the reference plane is the plane where the axial cross section of the reactor 1 is located, and the projections of the multiple guide plates relative to the reference plane do not overlap, that is, a second gap is provided between two adjacent guide plates along the axial direction, so that the multiple guide plates arranged along the axial direction of the reactor 1 are staggered, which facilitates the guiding and transportation of materials to the side of the accommodating chamber 20 away from the feed port 101.

[0086] In this way, there is a certain offset space between any two guide plates along the axial direction and radial direction of the reactor 1, avoiding the situation where the material needs to bypass the guide plates, resulting in a too long material conveying path, thereby reducing the risk of material accumulation or even blockage between the two guide plates.

[0087] In one embodiment, Figure 1-Figure 2 As shown, the reactor 1 includes a reactor body 11 and a reactor cover 12. The reactor cover 12 is arranged at at least one end of the reactor body 11 along the axial direction of the reactor body 11 and is detachably connected to the reactor body 11. The reactor body 11 and the reactor cover 12 can be connected by bolts, clamping, etc., which is convenient for the installation and removal of the reactor cover 12 and the reactor body 11, and is convenient for subsequent inspection and maintenance. Among them, the feed port 101 is arranged on at least one of the reactor body 11 and the reactor cover 12. For example, the feed port 101 is arranged on the reactor cover 12 to feed from the front end of the reactor body 11.

[0088] like Figure 1As shown, the reactor 1 further includes a reactor bottom 13, and a reactor cover 12 and the reactor bottom 13 are respectively arranged at both ends of the reactor body 11 along the axial direction of the reactor body 11, wherein the reactor bottom 13 and the reactor body 11 can be an integral structure, or can be fixed by welding or the like, or can be connected by bolts, clamping or other detachable methods. In addition, the reactor cover 12 and the reactor bottom 13 can be a flat plate structure, or a circular arc structure.

[0089] like Figure 1 As shown, a support rod 14 is provided inside at least one end of the reactor 1 along the axial direction of the reactor 1, that is, the support rod 14 is provided on at least one side where the reactor cover 12 and the reactor bottom 13 face each other, and the support rod 14 plays a supporting role to increase the overall strength of the reactor 1.

[0090] In one embodiment, Figure 1-Figure 2 As shown, the processing reaction device also includes a rotating shaft 4, which is inserted into the anti-blocking stirring structure 2 and the support rod 14. The support rod 14 provides support for the rotating shaft 4. There is an interference fit between the rotating shaft 4 and the anti-blocking stirring structure 2. The rotating shaft 4 drives the anti-blocking stirring structure 2 to rotate. There is a clearance fit between the rotating shaft 4 and the support rod 14. The support rod 14 does not affect the rotation of the rotating shaft 4, so that there is a gap between the anti-blocking stirring structure 2 and the inner wall of the reactor 1, so as to avoid the anti-blocking stirring structure 2 drooping and contacting the inner wall of the reactor 1 to cause bottom dragging, thereby ensuring the smooth rotation of the anti-blocking stirring structure 2.

[0091] like Figure 1-Figure 2 As shown, the processing reaction device also includes a rotation driving source 5, which is arranged outside the reactor 1. The rotation driving source 5 can specifically be a rotating motor. The output end of the rotation driving source 5 is directly connected to the rotating shaft 4, or the output end of the rotation driving source 5 is connected to the rotating shaft 4 through a reducer, so that the rotating shaft 4 drives the anti-blocking stirring structure 2 to rotate.

[0092] Under the control of the rotary drive source 5, the entire anti-blocking stirring structure 2 rotates slowly, so that the material is fully stirred in the accommodating chamber 20, and the uniformity of stirring and mixing is improved. At the same time, it can also prevent the local temperature from being too high, resulting in uneven heating.

[0093] If the rotating shaft 4 is an integral structure, when the kettle cover 12 is removed from the kettle body 11, the rotating shaft 4 needs to be pulled out from the kettle cover 12, which makes the operation process complicated and inconvenient to use.

[0094] To solve this problem, Figure 1-Figure 2As shown, the rotating shaft 4 includes a first connecting shaft 41 and a second connecting shaft 42. The first connecting shaft 41 passes through the reactor 1 and is connected to the output end of the rotating driving source 5. The second connecting shaft 42 is arranged in the reactor 1 and is connected to the anti-blocking stirring structure 2. The first connecting shaft 41 and the second connecting shaft 42 are detachably connected at one end close to each other.

[0095] In this way, the rotating shaft 4 is a split structure. When the kettle cover 12 and the kettle body 11 need to be disassembled, the second connecting shaft 42 can be placed in the reactor 1 and remain unchanged, and the second connecting shaft 42 is disconnected from the first connecting shaft 41. Then the rotating drive source 5, the first connecting shaft 41 and the kettle cover 12 can be separated from the kettle body 11 as a whole, and the first connecting shaft 41 does not need to be separated from the kettle cover 12 again, which simplifies the operation steps; when the kettle cover 12 and the kettle body 11 need to be installed, the rotating drive source 5, the first connecting shaft 41 and the kettle cover 12 can be installed to the kettle body 11 as a whole, and the installation process can be completed by only connecting the first connecting shaft 41 and the second connecting shaft 42 to each other.

[0096] The first connecting shaft 41 and the second connecting shaft 42 can be connected in a detachable manner by a coupling, a double-headed sleeve, etc.

[0097] Since the kettle cover 12 and the kettle body 11 are detachably connected, when the kettle cover 12 is removed from the kettle body 11, a discharge port 102 can be formed between the kettle cover 12 and the kettle body 11. At this time, there is no need to add an additional discharge port 102, thereby reducing production costs. After the reaction is completed, the material can be directly discharged from the kettle body 11 with a larger opening, and the unloading speed is relatively fast.

[0098] However, if the axial length of the reactor 1 is relatively long, the material near the bottom 13 of the reactor is difficult to be discharged from the discharge port 102. Figure 1 As shown, the rotating shaft 4 further includes an extension shaft 43 , which is disposed between the first connecting shaft 41 and the second connecting shaft 42 , and the extension shaft 43 is detachably connected to the first connecting shaft 41 and the second connecting shaft 42 .

[0099] During normal stirring, the kettle cover 12 is arranged on the kettle body 11, and the lengths of the first connecting shaft 41 and the second connecting shaft 42 are adapted to the lengths of the kettle cover 12 and the kettle body 11, and there is no need to add an extension shaft 43 between the first connecting shaft 41 and the second connecting shaft 42; when unloading is required, since the kettle cover 12 is separated from the kettle body 11 and a discharge port 102 is formed therebetween, the first connecting shaft 41 and the second connecting shaft 42 cannot still be directly connected. Since there is a gap between the two connecting shafts, the extension shaft 43 is used to fill the gap to facilitate the connection between the first connecting shaft 41 and the second connecting shaft 42.

[0100] After the reaction is completed, circulating water is used to quickly cool the materials. After the reaction is completed, the kettle cover 12 needs to be opened to unload the materials. The rotary drive source 5 drives the anti-blocking stirring structure 2 to rotate in the opposite direction through the rotating shaft 4, so that the materials that have completed the reaction in the anti-blocking stirring structure 2 are discharged from the discharge port 102, which is convenient for unloading the materials.

[0101] In this way, the forward rotation of the anti-blocking stirring structure 2 is used for stirring and mixing the materials, and the reverse rotation of the anti-blocking stirring structure 2 is used for unloading the materials. It not only satisfies the functions of material mixing and unloading at the same time, but also does not require the addition of additional components. It has multiple uses and strong functionality.

[0102] In one embodiment, Figure 1-Figure 2 As shown, the treatment reaction device also includes a heat-insulating layer 7, which is arranged on at least one of the inner wall and the outer wall of the reactor 1. The heat-insulating layer 7 is made of heat-insulating material. The heat-insulating layer 7 keeps the reactor 1 warm and reduces heat loss.

[0103] In one embodiment, the processing reaction device also includes a sensor 8, which is at least partially disposed in the reactor 1 and is used to detect at least one of the temperature, humidity and pressure in the reactor 1. The sensor 8 is used to realize real-time monitoring of various parameters in the reactor 1 to ensure the reaction effect of the materials.

[0104] After pretreatment by the treatment reaction device, the hemicellulose removal rate of the material is about 60% to 80%, and the cellulose retention rate is about 85%. After the pretreatment, the biomass is enzymatically hydrolyzed, and the enzymatic hydrolysis rate can reach 80%.

[0105] Exemplarily, a mixed system (biomass straw and pretreatment liquid) with the same solid-liquid ratio, wherein the biomass straws have the same length, is placed in a traditional vertical ribbon stirring reactor for pretreatment. The biomass straws can cause the stirring structure to lock, causing the equipment to fail to operate normally. A mixed system with the same solid-liquid ratio, wherein the biomass straws have the same length, is placed in the containing chamber 20 of the anti-blocking stirring structure 2 for pretreatment. The hemicellulose removal rate of the material is 20% to 40%, and the cellulose retention rate is about 90%. The pretreated biomass is enzymolyzed, and the enzymolysis rate is about 40% to 50%.

[0106] The processing reaction device provided in this embodiment can adjust the feeding speed of the material guiding structure 6, the steam temperature, and the rotation speed of the anti-clogging stirring structure 2, that is, according to different pretreatment process conditions of the material, the steam temperature, the feeding speed, the material mixing speed, or the feeding speed of the material guiding structure 6 is changed, thereby adjusting the retention time of the material in the reactor 1, or changing the temperature and pressure of the reactor 1 to achieve a good pretreatment effect.

[0107] The treatment reaction device provided in this embodiment has the advantages of good material mixing performance, uniform heating, and not easy to be blocked during the high temperature and high pressure pretreatment process.
