When the fluid passes through the small gap, the flow is blocked and a high pressure is formed, causing various substances in the fluid to undergo strong shearing, impact, cavitation explosion, turbulence and other effects, so that the fluid material after passing through the homogenization valve group is ultra-finely refined and evenly dispersed; however, at present, when the homogenizer is used for fibrous raw materials such as multi-walled carbon nanotubes, single-walled carbon nanotubes, bio-based nanofibrillated cellulose, cotton and linen fibers, viscose fibers, ceramic or glass inorganic fibers, and difficult-to-disperse raw materials such as graphene, there are still problems with poor dispersion and fragmentation effects.

Those skilled in the art can reasonably determine the specific meanings of the above words in the present invention in combination with the specific content of the technical solution.
[0023] Refer to Figures 1 to 6, the high-efficiency homogenization valve group according to the embodiment of the first aspect of the present invention includes a valve body 100 and a homogenization component 200. The valve body 100 is provided with a homogenization channel 110, and the homogenization channel 110 is provided with a turbulator ring 111 protruding radially; the homogenization component 200 is arranged in the homogenization channel 110; the homogenization component 200 includes a first valve core 210 and a second valve core 220. The second valve core 220 is provided with a homogenization groove 222, the first valve core 210 covers the second valve core 220, and the end wall of the first valve core 210 and the homogenization groove 222 form a homogenization cavity; the first valve core 210 is provided with a feed hole 211, the feed hole 211 communicates the homogenization cavity and the inlet end of the homogenization channel 110, and the second valve core 220 is provided with a discharge hole 221, the discharge hole 221 communicates the homogenization cavity and the outlet end of the homogenization channel 110; wherein, the homogenization groove 222 includes a confluence channel 2222 and a collision channel 2221, the collision channel 2221 is communicated with the confluence channel 2222, and the discharge hole 221 is arranged in the confluence channel 2222. When the fluid solution flows forward through the homogenization channel 110, a reverse backflow will be formed at the turbulator ring 111, and the backflow solution collides with the forward-flowing solution to form turbulence, thereby realizing the preliminary shearing of the fluid solution; after the fluid solution enters the homogenization cavity through the feed hole 211, the fluid solution undergoes high-speed collision in the collision channel 2221, thereby realizing the secondary high-speed shearing of the fluid solution, thereby improving the dispersion and fragmentation effects of the fibrous raw materials in the fluid solution. The above-mentioned forward flow of the fluid solution through the homogenization channel 110 means that the fluid solution flows from the inlet end to the outlet end of the homogenization channel 110, and the reverse backflow refers to Figure 1 as shown.
[0024] Further, in this embodiment, the depth of the collision channel 2221 is preferably less than 1 mm, and the width of the collision channel 2221 is greater than the depth, which is convenient for the fibrous raw materials or graphite raw materials to collide at high speed in an unfolded state, improving the dispersion and fragmentation effects of the raw materials. The depth of the collision channel 2221 can be specifically set according to the ratio of the length of the raw material to be homogenized to the pipe diameter. For example, if the raw material to be homogenized is graphite powder and graphene is obtained through the homogenization valve group of this embodiment, the depth of the collision channel 2221 can be preferably set to a set multiple of the particle size of the graphite particles, for example, set to 3 to 10 times the particle size depth of the graphite particles. The width W of the collision channel 2221 and the depth D of the collision channel 2221 preferably satisfy: W≥3D. The depth D of the collision channel 2221 refers to Figure 2 as shown, and the width W of the collision channel 2221 refers to Figure 4 as shown. By setting the width W of the collision channel 2221 to be significantly greater than the depth D, during the collision, it is difficult for the fibrous raw materials to stack in the depth direction of the collision channel 2221, and it is convenient for the fibrous raw materials to unfold, so that the fibrous raw materials or graphite raw materials can more achieve "head-on" collisions, improving the dispersion and fragmentation effects of the fibrous raw materials and graphite raw materials.
[0025] Currently, most of the homogenizing equipment on the market adopts a cylindrical collision channel 2221. In order to increase the crushing effect on the fibrous raw materials and graphite raw materials and make the fibrous raw materials and graphite raw materials achieve a "tit-for-tat" collision, it is necessary to reduce the inner diameter of the collision channel 2221 as much as possible. However, the reduction in the inner diameter of the collision channel 2221 can easily lead to blockage of the collision channel 2221, affecting the crushing efficiency and crushing effect. The flat collision channel 2221 in this embodiment is not easy to be blocked, and can achieve a good crushing effect on the fibrous raw materials and graphite raw materials, greatly improving the crushing efficiency.
[0026] Reference Figure 4 As shown, in the embodiment of the present invention, there are multiple collision channels 2221, and the multiple collision channels 2221 are arranged at intervals along the extension direction of the confluence channel 2222. The extension direction of the confluence channel 2222 is perpendicular to the extension direction of the collision channel 2221. The confluence channel 2222 passes through the multiple collision channels 2221, and the multiple collision channels 2221 are all connected to the confluence channel 2222. Specifically, the homogenizing tank 222 includes a collision area 230, and the collision area 230 is provided with a dividing bar 240. The dividing bar 240 is used to separate the collision area 230 into multiple collision channels 2221. The multiple collision channels 2221 can improve the collision efficiency of the raw materials, thereby reducing the number of times the raw materials circulate in the homogenizing component 200. There are multiple discharge holes 221 to facilitate the rapid discharge of the fluid solution. The specific positions of the multiple discharge holes 221 can be specifically set according to actual conditions. Exemplarily, refer to Figure 4 As shown, there are two discharge holes 221 which are respectively arranged at the two ends of the converging channel 2222, so that the raw materials can flow out after sufficient collision.
[0027] Further, the first valve core 210 is provided with a plurality of feed holes 211, and the plurality of feed holes 211 are all connected to the collision area 230, and the plurality of feed holes 211 are symmetrically arranged about the confluence channel 2222. Figure 3 As shown, there are two feed holes 211, which are respectively connected to the collision area 230 and are preferably as far away from the collision channel 2221 as possible, so as to facilitate the uniform distribution of the fluid solution into the multiple collision channels 2221; the multiple feed holes 211 are symmetrically arranged about the confluence channel 2222, so as to facilitate the uniform distribution of the fluid solution into the collision channels 2221 on both sides of the confluence channel 2222, thereby improving the dispersion and crushing effects of the fluid solution.
[0028] In the embodiment of the present invention, the collision area 230 includes a first edge 231 and a second edge 232 symmetrically arranged, the first edge 231 and the second edge 232 are symmetrically arranged about the confluence channel 2222, the confluence channel 2222 is arranged in the middle of the collision area 230, and both ends of the confluence channel 2222 extend out of the collision area 230.Figure 4 As shown, after the homogeneous valve group of this embodiment is installed, the two feed holes 211 of the first valve core 210 respectively correspond to the middle positions of the first edge 231 and the second edge 232. Preferably, both the first edge 231 and the second edge 232 are arc-shaped edges, and both ends of the first edge 231 and the second edge 232 extend towards the direction close to the confluence channel 2222, so as to facilitate the rapid flow of the fluid solution towards the collision channels 2221 near both ends of the confluence channel 2222, and can make the amount distribution of the fluid solution in the multiple collision channels 2221 uniform.
[0029] Refer to Figure 1 As shown, there are multiple turbulence rings 111 in the embodiment of the present invention. The multiple turbulence rings 111 are arranged at intervals along the material flow path direction of the homogeneous channel 110, and the multiple turbulence rings 111 can enhance the turbulence effect on the fluid solution in the homogeneous channel 110. The cross-sectional shape of the turbulence ring 111 can be set according to the actual situation. For example, it can be set as an arc or a rectangle, that is, the inner side wall of the turbulence ring 111 can be set as an arc surface or a plane. Preferably, the inner side wall of the turbulence ring 111 is set as an arc surface to reduce the loss of dynamic potential energy caused by turbulence, reduce the damage to the inner side wall of the turbulence ring 111 caused by turbulence, and at the same time increase the reverse flow rate and speed caused by the turbulence ring 111.
[0030] Furthermore, the inner diameters of the multiple turbulence rings 111 in this embodiment can be set to be equal or unequal. For example, along the material flow path direction of the homogeneous channel 110, the inner diameters of the multiple turbulence rings 111 can increase in sequence, or the inner diameters of the multiple turbulence rings 111 can decrease in sequence, or the inner diameter of the middle turbulence ring 111 is larger than the inner diameters of the turbulence rings 111 at both ends, or the inner diameter of the middle turbulence ring 111 is smaller than the inner diameters of the turbulence rings 111 at both ends, etc. Through experiments, in order to further enhance the turbulence effect caused by the turbulence ring 111, preferably along the material flow path direction of the homogeneous channel 110, the inner diameters of the multiple turbulence rings 111 increase in sequence.
[0031] It can be conceived that along the material flow path direction of the homogeneous channel 110, the turbulence ring 111 can be arranged at the front end or the rear end of the homogeneous component 200 as shown in Figure 1 . That is, the fluid solution can first flow through the turbulence ring 111 and then enter the homogeneous component 200, or it can first flow through the homogeneous component 200 and then enter the turbulence ring 111, which is not limited in this embodiment.
[0032] In the embodiment of the present invention, the turbulence ring 111 can be arranged on the inner side wall of the homogeneous channel 110, or can be formed by a detachable homogeneous module 300, so as to facilitate changing the inner diameter of the turbulence ring 111 according to different raw materials to be broken. Refer to Figure 5 、 Figure 6As shown, the homogenization module 300 includes a through-hole 310 passing through the homogenization module 300. The through-hole 310 includes a first flared section 311, a straight section 312, and a second flared section 313. The straight section 312 connects the first flared section 311 and the second flared section 313. Along the radial direction of the homogenization module 300, the inner diameters of the first flared section 311 and the second flared section 313 gradually increase outward along the straight section 312. The first flared section 311 and the second flared section 313 cooperate to form a turbulence ring 111. By changing the shapes and sizes of the first flared section 311 and the second flared section 313, different types of turbulence rings 111 can be formed. For example, the cross-sections of the first flared section 311 and the second flared section 313 can be set as Figure 5 the arc shown or Figure 6 the straight line shown, Figure 5 the inner side walls of the first flared section 311 and the second flared section 313 shown in can also be concave or convex, which is not limited in this embodiment.
[0033] Furthermore, the inner diameter of the straight section 312 of the through-hole 310 can be set to be equal to or unequal to the inner diameter of the homogenization channel 110. For example, the inner diameter of the straight section 312 can be set to be greater than or less than or equal to the inner diameter of the homogenization channel 110, which is not limited in this embodiment.
[0034] In the embodiment of the present invention, the number of the homogenization modules 300 can be set according to the actual situation, and the installation position of the homogenization modules 300 can also be set according to the actual situation. For example, along the material flow path direction of the homogenization channel 110, multiple homogenization modules 300 can be arranged in parallel at the front end of the homogenization assembly 200, or multiple homogenization modules 300 can be arranged in parallel at the rear end of the homogenization assembly 200, or homogenization modules 300 are provided at both the front and rear ends of the homogenization assembly 200.
[0035] The homogenizer according to the second aspect embodiment of the present invention includes a separation device and the above-mentioned homogenization valve group. The separation device is used to receive the fluid solution discharged by the high-efficiency homogenization valve group and separate the homogenized raw materials in the fluid solution. The separation device includes a separation and extraction tank. The inside of the separation and extraction tank is at normal pressure or low pressure. After the fluid solution after high-efficiency homogenization enters the separation and extraction tank, it will become a micro-nano aerosol state. The supercritical carbon dioxide liquid returns to the gaseous state after returning to normal pressure or low pressure. The carbon dioxide gas enters the recovery, compression and recycling device after filtration, and the remaining materials become finished products through hierarchical recovery. Since the homogenizer includes the above-mentioned homogenization valve group, it has at least all the beneficial effects of the homogenization valve group, which will not be elaborated here.
[0036] The homogenization method according to the third aspect embodiment of the present invention is applicable to the above-mentioned homogenizer. The homogenization method includes the following steps: Input a fluid solution into the high-efficiency homogenization valve group for homogenization operation and cycle for a set number of times; The high-efficiency homogeneous valve group outputs a fluid solution to a separation device for separation and extraction operations; Among them, the fluid solution is composed of raw materials, liquid solvents, dispersants, and supercritical carbon dioxide solvents. For example, for the production of graphene, the raw material can be graphite powder; the liquid solvent can be one or more of inorganic solvents such as water, organic solvents such as alcohols and toluenes, and can also include materials that prevent the raw materials from agglomerating again after dispersion, such as polyvinylpyrrolidone, carboxymethyl cellulose, polyvinylidene fluoride, polystyrene butadiene, etc. The appropriate liquid solvent can be selected according to different raw materials. Preferably, the particle size of the liquid solvent used is close to that of the raw material, so as to facilitate the impact on the raw material and enable the raw material to obtain better intercalation, dispersion, and fragmentation effects. Currently, for the dispersion and fragmentation of fibrous raw materials and difficult-to-disperse raw materials such as graphene, usually only supercritical carbon dioxide solvent is mixed with the raw materials. For example, in a patent application for a method for preparing graphene by supercritical fluid explosion method with the application number CN201510994548.7, only supercritical carbon dioxide and graphite powder are mixed as the fluid solution. In this application, by adding a liquid solvent to the fluid solution, according to the calculation of specific surface area and volume ratio, under the condition of meeting the dosage for good dispersion of the raw materials, the addition amount of the supercritical carbon dioxide solvent can be reduced, thereby reducing the preparation cost, reducing the investment in the recovery system, and improving the separation and extraction efficiency of the raw materials; the liquid solvent is difficult to be compressed, and using a liquid solvent with a particle size close to that of the raw material can significantly improve the dispersion and fragmentation effects on the raw materials. In the fluid solution, preferably, the raw materials and the supercritical carbon dioxide solvent account for 0.1% to 99.9% of the total volume of the fluid solution; if in terms of specific surface area ratio, in the fluid solution, preferably, the ratio of the specific surface area of the supercritical carbon dioxide solvent to the specific surface area of the raw materials is 0.1 to 30; if in terms of volume ratio, in the fluid solution, preferably, the ratio of the volume of the supercritical carbon dioxide solvent to the volume of the raw materials is 0.1 to 50.
[0037] Furthermore, by adding a liquid solvent to the fluid solution, the use of the supercritical carbon dioxide solvent can be reduced. The supercritical carbon dioxide solvent will be converted into a gas in the separation and extraction tank to facilitate the separation of the raw materials, and when the supercritical carbon dioxide is converted into a gas, a huge expansion will occur. Therefore, higher requirements are imposed on the structural strength of the separation device, and a larger container is required to store the gaseous carbon dioxide, resulting in higher manufacturing costs and maintenance costs of the equipment; in this embodiment, through a scientific formula, the use of supercritical carbon dioxide is minimized, the structural strength of the separation device can be appropriately reduced, and the volume of the container for storing the gaseous carbon dioxide can be reduced, thereby reducing the manufacturing costs and maintenance costs of the equipment.
