Description

Technical Field

[0001] The utility model belongs to the technical field of extraction in chemical separation, and in particular relates to a baffle extraction tower containing solid extraction operation. Background Art

[0002] Solvent extraction is an important separation technology in chemical and metallurgical processes. It has the advantages of high selectivity, strong adaptability, good separation effect and easy large-scale continuous production. It is currently widely used in hydrometallurgy, nuclear chemical industry, petrochemical industry, environmental engineering, new energy and new materials and other fields. The realization of the liquid-liquid extraction process depends on the development of extraction equipment. With the continuous expansion of production scale and the increasing complexity of separation objects, the requirements for extraction equipment are also getting higher and higher. In practical production, liquid-liquid-solid extraction systems containing solid phases are often encountered. The solid particles in this type of extraction gas are easily deposited in the extraction equipment and reduce the equipment flux, thereby causing equipment blockage and affecting its normal operation and long-term operation. Therefore, it is very important to develop an extraction device that is resistant to blockage, high-throughput and can achieve continuous liquid-solid discharge for separation of solid-containing extraction operations while ensuring high mass transfer efficiency.

[0003] The pulse baffle extraction tower has the advantages of simple structure, large flux, no internal moving parts, good sewage discharge performance and easy maintenance. Compared with other mechanical stirring extraction towers, this type of extraction tower has a wider operating area, increased operational stability, and can also handle materials containing solid particles. However, the existing pulse baffle extraction tower is only suitable for low solid content operation. When the solid content of the system is too high, the particles will be excessively deposited and adhered at the connection between the outer ring plate and the tower wall, and produce a "snowball" effect, rapidly accumulating and expanding, affecting the normal operation of the equipment, and in severe cases, causing the extraction tower to be blocked.

[0004] The utility model patent publication with publication number CN102698467A discloses a method for extracting and purifying natural uranium using a vibrating annular baffle extraction tower. By setting annular baffles under vibration conditions, it is possible to process solid-containing raw materials, but the baffles are all flat plate structures, and the vibration has limited effect on excessive deposition and adhesion as well as enrichment. In addition, it is set as a central column, and the flux is limited. Utility Model Content

[0005] In view of the above technical problems, the utility model proposes an improved pulse baffle extraction tower suitable for solid-containing extraction operations. The internal components are improved and designed based on the analysis of the flow field structure in the baffle extraction tower, so as to reduce the deposition of solid phase on the outer ring plate and the inner plate, eliminate tower body blockage, increase flow flux, and realize continuous discharge of solid phase, so as to improve the extraction tower's processing capacity for solid-containing extraction systems.

First, the outer ring plate and the inner ring plate of the traditional pulse baffle extraction tower are improved, and a specific inclined surface design structure is adopted to make the surface of the internal component produce a gravity component along the inclined surface direction, which promotes the movement of particles; the multiphase flow field structure in the baffle extraction tower has a better fit with the inclined surface plate, eliminating the flow dead zone in the tower and preventing solid phase deposition; and the three-rod edge support method is combined to eliminate the area occupied by the single-rod center support method on the center of the extraction tower, thereby improving the flux of the extraction tower.

[0059] So far, the device structure of the utility model has been exemplarily shown. The specific use effects of the device of the utility model are illustrated and compared with usage examples below.

[0060] Example 1

[0061] 20% P204-kerosene was used as the light phase, and an aqueous solution containing Ni, Co, Mn, Mg, Cu, Zn, Ca, Fe (Ca 2+>0.2g / L) as the heavy phase for fluid mechanics experiments. The experimental conditions are that the total flow rate of the two phases is 350L / h, the flow ratio of the organic phase to the aqueous phase is 0.8-1.5, and the organic phase is continuous. The above-mentioned baffle extraction tower containing solid extraction operation of the utility model is used. The operation steps are to fill the baffle extraction tower containing solid extraction operation of the utility model with 20% P204-kerosene from the light phase inlet, and the aqueous phase is input through the heavy phase distributor, and the two-phase flow rate is adjusted to 200L / h for the organic phase and 150L / h for the aqueous phase. The pulse stroke is set to a fixed value of 0.5mm, and the pulse frequency control device is turned on to make the liquid surface fluctuate periodically. The product of the amplitude and frequency of the vibration of the droplets in the extraction tower is the pulse intensity. The flow rate of the heavy phase outlet in the heavy phase clarification section (i.e., the lower tower body) is adjusted to maintain the height of the interface between the light phase and the heavy phase at the clarification section stable and unchanged.

[0062] Comparative Example 1

[0063] This comparative example adopts the existing traditional pulse baffle extraction tower, the outer ring plate and the inner ring plate of the traditional pulse baffle extraction tower are both flat plates, and the support rod component is a single-rod center-supported baffle extraction tower with a central support, and the plate spacing and opening rate of the outer ring plate and the inner ring plate of the traditional pulse baffle extraction tower are kept the same as the specific implementation method of the utility model used in Example 1, and the same extraction raw materials, parameters and methods as in Example 1 are used. The comparative experimental data of Example 1 and Comparative Example 1 are shown in Table 1. Table 1 is a comparison table of fluid mechanics experimental results of Example 1 and Comparative Example 1.

[0064] Table 1

[0065] Pulse intensity Continuous phase flow rate Dispersed phase flow rate Example 1 Comparative Example 1 0 0.002 0.0015 O X 0 0.004 0.003 XO X 0.005m / s 0.002 0.0015 O XO 0.005m / s 0.004 0.003 O X 0.01m / s 0.004 0.003 O X 0.015m / s 0.004 0.003 O XO 0.02m / s 0.004 0.003 O O

[0066] Note: X indicates flooding, O indicates good operation, and XO indicates poor operation.

[0067] Through the comparative data in Table 1, it can be obtained that under different pulse intensities and different flow rates, the overall operational flexibility of the three-rod edge-supported baffle extraction tower of the utility model is higher than that of the single-rod center-supported baffle extraction tower of Comparative Example 1. In particular, as shown in Table 1, the traditional baffle extraction tower of Comparative Example 1 cannot operate normally under the condition of no pulse intensity, while the baffle extraction tower of the present invention can also achieve good operation at low flow rates. For the traditional baffle extraction tower of Comparative Example 1, stable operation at a low flow rate can only be achieved under high pulse conditions (pulse intensity>0.02m / s), while the extraction tower of the present invention can achieve stable operation of the extraction equipment when the pulse is 0.005m / s. Therefore, the extraction tower of the present invention is not only suitable for extraction systems containing solid materials, but also consumes significantly less energy than the traditional extraction tower of Comparative Example 1.

[0068] By performing a tower droplet behavior and fluid mechanics simulation on Example 1 and Comparative Example 1, the specific Figures 11 to 13 As shown, the simulation process sets the tower diameter to DN250, the opening rate to 25.6%, the spacing between the inner ring plate and the outer ring plate to 113 mm, and the angles between the top surfaces of the inner cone plate and the outer ring plate and the horizontal plane (i.e., α and β) to 15°. Fig.11 (a) is the velocity flow field distribution diagram of comparative example 1, Fig.11 (b) is the velocity flow field distribution diagram of Example 1, Fig.12 (a) is the flow dead zone distribution diagram of comparative example 1, Fig.12 (b) is the flow dead zone distribution diagram of Example 1, Fig.13 (a) is the solid content distribution diagram of Comparative Example 1, Fig.13 (b) is the solid content distribution diagram of Example 1.

[0069] Through the above analysis of the droplet behavior and fluid mechanics simulation in the tower, it can be seen that there is a big difference between the fluid vortex structure in the traditional extraction tower and the geometric structure of the tower. Fig.11 The vortex formed above the inner and outer ring plates shown in (a) is not fully developed and should be smaller than Fig.11 (b) shows the eddy current intensity, which leads to Fig.11 The eddy current area (grey) defined by velocity as shown in (a) is smaller than Fig.11 (b) shows the distribution of eddy current areas. Fig.12 The dead zone distribution (black) shown in (a) is larger than Fig.12 (b) The dead zone distribution shown; the elimination of flow dead zone is beneficial to reduce the deposition of solid phase, thus Fig.13 The solid volume fraction on the plate shown in (b) is less than Fig.13 The solid volume content shown in (a) proves that the design of the internal components of the utility model is not simply to set the upper surface of the baffle plate as an inclined structure, but through the setting of parameters such as the distance and area ratio between the various components, and the coordinated use of the dispersed setting of multiple rods (three rods in this embodiment), the turbulent characteristics of the eddy current between the plates can be fully utilized to prevent solid phase deposition, thereby improving the processing capacity of the entire tower for solid-containing extraction systems.

[0070] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
