Description

Technical Field

[0001] The present application relates to the technical field of chemical equipment, and in particular to an efficient extraction tower internal. Background Art

[0002] Liquid-liquid extraction is an important operation link in the petrochemical, chemical, metallurgical, pharmaceutical, environmental protection and other industries. Liquid-liquid extraction is a form of mass transfer. One or several compound components in a mixture solution are extracted with another liquid (called a solvent, which is immiscible with the solvent of the mixture solution), thereby achieving separation, enrichment and purification.

[0003] Extraction equipment is a type of mass transfer equipment used for extraction operations, which can achieve complete separation of components contained in the feed liquid; extraction equipment can be divided into mixer-settlers (extraction tanks), extraction towers and centrifugal extractors according to their structure.

[0004] Extraction equipment, also known as extractor, is a mass transfer equipment used for extraction operations. It can make the extractant and the feed liquid contact well and realize the complete separation of the components contained in the feed liquid. There are two types: graded contact and differential contact. In the extraction process, it is usually expected that the extractant is dispersed in the other phase in the form of droplets. This can increase the contact area between the two phases and improve the material transfer efficiency. The extraction equipment commonly used is the extraction tower. The extraction tower is also called the extraction tower. It is an important liquid-liquid mass transfer equipment and is widely used in chemical industry, petroleum refining, environmental protection and other industrial sectors. The extraction tower currently has the following different structures and types: such as packed extraction tower, sieve plate extraction tower, turntable extraction tower, vibrating sieve plate tower, multi-stage centrifugal extraction tower, etc.

[0005] The working principle of the existing sieve plate extraction tower is: the light phase (dispersed phase) is introduced into the bottom of the tower and dispersed through the sieve holes, then rises in the heavy phase (continuous phase), gathers into a layer of light liquid at the bottom of the upper sieve plate, disperses again, and gathers again. The dispersion process is the extraction mass transfer process; it is suitable for materials with high viscosity and high concentration gradient. The sieve plate extraction tower is widely used in chemical production processes due to its large processing capacity, simple structure and low cost, but the mass transfer effect of the sieve plate extraction tower is not ideal, and it cannot be chopped into droplets in time. The droplet diameter is large and the mass transfer area is small; the packed extraction tower has a better effect. It is equipped with packing inside, which can increase the contact area between the solvent and the raw material solution and improve the extraction efficiency. The packed extraction tower has a relatively simple structure and is easy to manufacture and maintain. Although the packed extraction tower has many advantages, it also has some shortcomings, such as: the packing layer will increase the flow resistance and cause a large pressure drop, the liquid is unevenly distributed, the packing is blocked and needs to be cleaned and replaced regularly, the tower diameter is large, the operation flexibility is limited, and it is difficult to handle high viscosity liquids.

[0006] Therefore, it is necessary to provide a new extraction tower internal to solve the technical problems existing in the above-mentioned extraction tower. Utility Model Content

Preferably, the fixed valve pieces 88 are evenly arranged on the outer side of the fixed installation part 87 and are integrally formed; the fixed valve piece 88 adopts any one of an arc shape, a circle, a semicircle, a clover shape, a triangle, a rhombus shape, a rectangle, an ellipse, and a tongue shape, or the orthographic projection shape of the fixed valve piece 88 on the inclined plate 1 or / and the inclined plate 2 is any one of an arc shape, a circle, a semicircle, a clover shape, a triangle, a rhombus shape, a rectangle, an ellipse, and a tongue shape. The fixed valve legs 89 are arranged between adjacent fixed valve discs 88 or on one side of the fixed valve disc 88. In the present embodiment, the fixed valve legs 89 are arranged between adjacent fixed valve discs 88, and the fixed valve legs 89 are connected to the inclined plate 1 or / and the inclined plate 2. The fixed valve legs 89 are arranged tilted, and the angle between the fixed valve legs 89 and the inclined plate 1 or / and the inclined plate 2 is 20°-80°.

[0054] Preferably, the shape of the sawtooth 91 includes straight sawtooth, curved sawtooth, polygonal sawtooth, etc. The shape of the sawtooth 91 has an important influence on the droplet breakup process and the size distribution of the droplets after breakage, thereby affecting the quality of the product and the separation efficiency; wherein, the straight sawtooth shape, due to its sharp edge, can produce a larger local stress concentration when contacting the droplet, thereby improving the droplet breakage efficiency. Compared with curved or polygonal sawtooth, the straight sawtooth may be more direct and effective in the cutting process. The cutting effect of the straight sawtooth on the droplet causes the droplet size distribution to be more uniform, because the straight edge of the sawtooth can ensure the consistency of the cutting to a certain extent; due to the characteristics of its shape, the curved sawtooth may produce a local stress concentration when cutting the droplet that is not as sharp as the straight sawtooth. Therefore, in some cases, the curved sawtooth is not as efficient as the straight sawtooth in terms of breakage efficiency. Compared with the straight sawtooth, the curved sawtooth will produce a wider particle size distribution. This is because the curved sawtooth This is caused by the uneven distribution of forces acting on the droplets during the cutting process; polygonal sawtooth has multiple edges and angles, which may produce multiple local stress concentration points when in contact with the droplets, which helps to break the droplets. Compared with single-edge straight sawtooth, polygonal sawtooth may exert forces on the droplets in different directions, thereby improving the crushing efficiency. Since the droplets are acted upon by forces in multiple directions, the polygonal sawtooth will cause the droplets to break into droplets of different sizes, thereby forming a wider particle size distribution; the design and application of the above-mentioned sawtooth are optimized according to specific process requirements and the physical properties of the droplets, such as: the size of the sawtooth needs to be small enough to ensure that the droplets can be effectively cut, and the sawtooth spacing needs to be appropriate to avoid bridging of droplets between the sawtooth, causing material blockage and affecting the crushing effect; material properties and usage conditions such as material viscosity, density, operating temperature and pressure will have an impact on crushing, and they all need to be considered during design, and this application does not make specific limitations here.

[0055] Embodiment three:

[0056] The difference between this embodiment and the second embodiment lies in the installation position of the fixed valve leg 89 and the shape of the fixed valve plate 88. Specifically:

[0063] Embodiment five:

[0064] The difference between this embodiment and the second embodiment lies in the shape of the fixed mounting portion 87, the number of fixed valve plates 88, and the number of fixed valve legs 89. Specifically:

[0065] like Fig.12 As shown, the fixed mounting portion 87 is in the shape of a square or its projection is a square, 12 fixed valve plates 88 are arranged on the outside of the fixed mounting portion 87, and 3 fixed valve plates 88 are arranged on the outside of each side length.

[0067] In the present application, the movement from the inside of the valve to the end of the fixed valve plate 88 has a downward secondary film pulling and breaking mass transfer effect, which ensures a better droplet cutting and breaking effect, and thus has the following advantages:

[0068] 1. Increase the contact area: Smaller and more broken droplets can significantly increase the contact area between the two liquid phases, which is beneficial to improve the efficiency of material transfer between phases and promote the separation process;

[0069] 2. Accelerate mass transfer: A larger contact area can make the mass transfer process occur faster, allowing the components to transfer more quickly between different phases, thereby accelerating the rate of liquid-liquid separation;

[0070] 3. Uniform mixing and separation: More uniform droplet breakage helps to form a more uniform mixing state, which can then achieve more orderly stratification and separation, improving the accuracy and effect of separation;

[0071] 4. Reduce separation time: Efficient droplet cutting and crushing can shorten the time required to achieve a good separation effect and improve the overall separation efficiency;

[0072] In addition, the zigzag structure design can increase the contact area and turbulence of the liquid, thereby further improving the extraction efficiency.
