Description

Technical Field

[0001] The utility model relates to the technical field of extraction equipment, in particular to a high-efficiency energy-saving extraction tower. Background Art

[0002] Extraction tower, also known as extraction tower, is a liquid-liquid mass transfer equipment commonly used in chemical industry, petroleum refining, environmental protection and other industrial sectors. Liquid-liquid extraction is a way of mass transfer. One or several compound components in a mixture solution are extracted with another liquid that is immiscible with the solvent of the mixture solution to separate, enrich and purify it. Its internal structure uses gravity or mechanical action to break a liquid into droplets and disperse them in another continuous liquid for liquid-liquid extraction. In production, in order to improve the efficiency of liquid-liquid mass transfer equipment, it is often necessary to supply external power, such as stirring, pulsing and vibration. There are common problems such as long time consumption and low efficiency. Summary of the invention

[0003] A high-efficiency and energy-saving extraction tower (see Figures 1 and 2), comprising a cylindrical tower body (2), a heavy liquid inlet (1), a light liquid inlet (3), a heavy liquid outlet (8) and a light liquid outlet (4) are arranged on the side wall of the tower body, and an inclined sieve plate (5) is arranged in the center of the tower body (2). In order to further achieve the purpose of the present invention, the inclined sieve plate (5) is formed by shearing a complete elliptical sieve plate formed by the intersection of the inclined sieve plate and the cylindrical tower body along a 1 / 10 position perpendicular to one end of the long axis. The angle between the inclined sieve plate (5) and the horizontal line is 25-30°, and the side of the sieve plate with one-tenth removed is located at the upper end of the inclined sieve plate, leaving a gap between the inclined sieve plate and the tower body, and the lower end of the inclined sieve plate is still elliptical and intersects with the cylindrical tower body (2).

[0004] In order to further achieve the purpose of the present invention, a plurality of small V-shaped openings (6) arranged in an array are cut on the inclined screen plate (5), and the small V-shaped plate (7) formed by the opening is adjusted to a direction perpendicular to the plane of the inclined screen plate, the height: bottom edge of the small V-shaped plate (7) is 2:1, the height is about 1 / 10 of the length of the inclined screen plate (5), and the spacing between the small regular tetrahedrons is about the length of the bottom edge of a small V-shaped plate (7). When installing the inclined screen plate, one side of the small V-shaped plate (7) is facing downward. The inclined screen plate is arranged in a folded line ascending manner, and a certain gap is left between the partitions.

[0005] Compared with the prior art, the utility model can produce the following positive effects.

[0006] In traditional processes, in order to improve the efficiency of liquid-liquid mass transfer equipment, it is often necessary to add external power, such as stirring, pulsation and vibration. In the utility model, the buoyancy of the light liquid in the heavy liquid and the shear stirring effect of the small V-shaped plate on the sieve plate are utilized to disperse the light liquid into smaller droplets without the need for external kinetic energy, thereby increasing the contact area with the heavy liquid, improving the extraction efficiency and saving costs.

[0010] An inclined sieve plate extraction tower (see FIGS. 1 and 2) comprises a cylindrical tower body (2), a heavy liquid inlet (1), a light liquid inlet (3), a heavy liquid outlet (8) and a light liquid outlet (4) are arranged on the side wall of the tower body, and an inclined sieve plate (5) is arranged in the center of the tower body (2). In order to further achieve the purpose of the utility model, the inclined sieve plate (5) is formed by shearing a complete elliptical sieve plate formed by the intersection of the inclined sieve plate and the cylindrical tower body along one-tenth of one end perpendicular to the long axis. The angle between the inclined sieve plate (5) and the horizontal line is 25-30°, and the side of the inclined sieve plate with one-tenth removed is located at the upper end of the inclined sieve plate, leaving a gap between the inclined sieve plate and the tower body, and the lower end of the inclined sieve plate is still elliptical and intersects with the cylindrical tower body (2).

[0011] In order to further achieve the purpose of the utility model, a plurality of arrayed small V-shaped openings (6) are cut on the inclined screen plate (5), and the small V-shaped plate (7) formed by the opening is adjusted to a direction perpendicular to the plane of the partition plate, the height: bottom edge of the small V-shaped plate (7) is 2:1, the height is about 1 / 10 of the length of the inclined screen plate (5), and the spacing between the small regular tetrahedrons is about the length of the bottom edge of a small V-shaped plate (7). When installing the inclined screen plate, one side of the small V-shaped plate (7) is facing downward. The inclined screen plate is arranged in a folded line ascending manner, and a certain gap is left between the partitions.

[0012] principle.

[0013] When the sieve plate extraction tower is working, the light liquid first enters the extraction tower 2 from the bottom inlet 3. Due to the buoyancy, a small amount of light liquid will move upward through the small V-shaped opening 6 and pass through the inclined sieve plate 5. Most of the light liquid will move along the inclination angle direction of the first layer of inclined sieve plates. During the inclined upward movement, the light liquid is continuously dispersed into smaller droplets under the cutting action of the small V-shaped plate 7 on the rough surface. The light liquid that has passed through one layer of inclined sieve plates then continues to move along the inclination angle direction of the next inclined sieve plate through the gap of the inclined sieve plates, thereby achieving a small part of vertical rise and most of the zigzag rise in contact with the heavy liquid. During the zigzag rise, the light liquid is continuously sheared and dispersed into smaller droplets by the small V-shaped plate 7. In addition, the small part of the light liquid that rises vertically increases the power and contact area of ​​the light and heavy liquid mixing in the entire extraction process, thereby improving the extraction efficiency without providing external power.

[0014] It should be understood that the parts not elaborated in detail in this specification belong to the prior art. The above description of the preferred embodiment is relatively detailed, but it cannot be regarded as limiting the scope of protection of the patent of this utility model.
