Description

Technical Field

[0001] The utility model belongs to the technical field of petrochemical distillation separation equipment, and particularly relates to a filler baffle type liquid-liquid stratification tank. Background Art

[0002] In chemical operation units such as extraction and stratification, two immiscible dispersed systems are often encountered, and the two liquids need to be separated. Among them, gravity separation is a commonly used method in chemical production. The stratification tank uses the difference in density of the two liquids and the effect of gravity to achieve effective separation of different liquids.

[0003] There is a baffle type liquid-liquid stratification tank, such as Figure 1 As shown, the raw material liquid is introduced into the tank from the feed port 2 of the tank body 1, and a lower baffle 5 is arranged on the side of the tank body 1 away from the feed port 2. After a period of static stratification, due to the difference in liquid density, the heavier liquid will gradually settle to the middle and lower part of the tank body 1, and the lighter liquid will gradually float to the middle and upper part of the tank body 1. After a certain amount of upper liquid accumulates, it will overflow to the right side of the lower baffle 5, and the lower liquid will remain on the left side of the lower baffle 5. The light phase liquid and the heavy phase liquid are respectively extracted, thereby achieving the purpose of separating the two liquids.

[0004] However, the above-mentioned baffle-type liquid-liquid stratification tank cannot completely separate the two liquids, the purity is low, the light and heavy phases are more entrained, and the static separation time is long, which will affect the separation efficiency of the raw liquid. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a filler baffle type liquid-liquid stratification tank.

[0006] The technical solution adopted by the utility model is as follows:

[0029] In order to better understand the purpose, structure and function of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings.

[0030] like Figure 2-Figure 3As shown, a filler baffle type liquid-liquid stratification tank comprises a tank body 1, wherein the two ends of the tank body 1 are provided with a left head 9 and a right head 10, the upper left end portion of the tank body 1 is provided with the feed port 2, the metal mesh filler layer, the metal perforated plate corrugated filler layer, the lower baffle 5 and the upper baffle 6 are sequentially arranged inside the tank body 1 and on the right side of the feed port 2, a distance is left between the top of the lower baffle 6 and the top of the tank body 1, a distance is left between the bottom of the upper baffle 5 and the bottom of the tank body 1, the heavy phase liquid production port 8 is provided at the lower end portion of the tank body 1, and a light phase liquid production port 7 is provided at the middle and upper part of the right head 10.

[0031] The utility model introduces a metal mesh filler 3 and a metal orifice plate corrugated filler 4 into the layered structure of the filler baffle type liquid-liquid stratification tank. The metal mesh filler 3 is made of metal mesh, and its structure is loose and uniform. It has the advantages of large specific surface area, small resistance, large flux, uniform liquid distribution, etc. After the mixed liquid enters the mesh filler, it can be evenly distributed, and the homogenization effect is good. Even at a low liquid phase load, a small amount of liquid can be evenly spread on the surface of the metal mesh; and the metal orifice plate corrugated filler 4 has a large gap, which can make the homogenized liquid better polymerized, and small droplets are aggregated into large droplets. In addition, the metal mesh filler 3 and the metal orifice plate corrugated filler 4 have the advantages of corrosion resistance, high temperature resistance, and high strength.

[0032] When in use, the raw material mixed liquid enters the filler baffle type liquid-liquid stratification tank through the feed inlet 2, and is first homogenized through the metal wire mesh filler layer. After homogenization, the mixed liquid is polymerized through the metal perforated plate corrugated filler layer, and the small droplets are polymerized into large droplets.

Among them, the lower baffle 5 can reduce the disturbance of the left material, so that the right material is separated in a relatively stable state, playing a buffering role; the combination of the upper baffle and the lower baffle enables the light phase liquid and the heavy phase liquid to achieve a better separation effect. The upper layer of liquid is extracted from the light phase liquid extraction port 7 on the right, and the lower layer of liquid is extracted from the heavy phase liquid extraction port 8 at the bottom of the tank; after the entire equipment is improved, the separated liquid has a higher purity, less entrainment, the time for separation of liquid and material is shortened, and the separation effect of liquid and material is obvious.

[0033] Among them, the metal mesh packing layer of the packing baffle type liquid-liquid stratification tank of the utility model is composed of a metal mesh packing 3 and a packing support structure 11 on both sides of the metal mesh packing 3; the metal perforated plate corrugated packing layer is composed of a metal perforated plate corrugated packing 4 and a packing support structure 11 on both sides of the metal perforated plate corrugated packing 4. The packing support structure 11 is made of metal and has a mesh structure. It can be fixed in the tank body 1 by nuts or welding. Figure 4 As shown, it plays a role in fixing the filler so that it does not become loose, thus making the metal wire mesh filler layer and the metal perforated plate corrugated filler layer more stable.

[0034] In addition, in the utility model of the packing baffle type liquid-liquid stratification tank, a support 15 is provided on the lower side of the tank body 1 to facilitate the fixing and installation of the packing baffle type liquid-liquid stratification tank. A drain port 12 is provided at the lower left end of the tank body 1 to facilitate the discharge of residual materials after liquid-liquid separation.
