Detailed Implementation

[0021] This utility model discloses a soybean oil pretreatment distillation tower. The following description, in conjunction with a preferred embodiment (Example 1), is shown in the accompanying drawings. Figure 1 The following figures further describe the specific embodiments of this utility model.

[0022] See attached diagram. Figures 1 to 8 , Figures 1 to 6 The soybean oil pretreatment distillation tower is shown from different perspectives. Figure 7 and Figure 8 The first direction partition assembly is shown separately.

[0023] Example 1.

[0024] Preferably, the soybean oil pretreatment distillation column includes a column body 100, a plurality of first-direction baffle assemblies 200, and a plurality of second-direction baffle assemblies 300. Both the first-direction baffle assemblies 200 and the second-direction baffle assemblies 300 are built into the column body 100, and the first-direction baffle assemblies 200 and the second-direction baffle assemblies 300 are alternately distributed, wherein:

[0025] The tower body 100 includes a tower body cylinder 101 and a first air inlet 110, a liquid outlet 130, and multiple air outlets 140 integrally formed with the tower body cylinder 101. The first air inlet 110 and the liquid outlet 130 are located at the bottom end of the tower body cylinder 101, the first air inlet 110 is higher than the liquid outlet 130, and the air outlets 140 are higher than the first air inlet 110. There is a gap between two adjacent air outlets 140 so that products with different oil content can be obtained at air outlets 140 at different heights according to the difference in parameters such as boiling point.

[0026] The column body 100 also includes a second air inlet 120, which is located in the middle of the column body 101 and integrally formed with it. This second air inlet 120 serves as a supplement to the first air inlet 110, allowing the oil-gas mixture to be distilled to enter the column body 100 through either the first air inlet 110 or the second air inlet 120. Furthermore, depending on the differences in boiling points and other parameters between different batches of oil-gas mixtures, the mixture can be selectively introduced into the column body 100 through either the first air inlet 110 or the second air inlet 120, thus achieving better gas-liquid phase separation.

[0027] The structure of the second directional baffle assembly 300 is the same as that of the first directional baffle assembly 200. The second directional baffle assembly 300 and the first directional baffle assembly 200 are mirror-symmetrically distributed with respect to the axial direction of the tower body 101. This allows the oil-gas mixture to be distilled to be introduced into the tower body 100 through the first air inlet 110 or the second air inlet 120, so as to extend the upward path of the oil-gas mixture as much as possible. The countercurrent flow of the gas and liquid phases (vapor upward and oil downward) can achieve multiple equilibrium separations and improve the separation efficiency.

[0028] The first air inlet 110, the second air inlet 120, the liquid outlet 130, and the air outlet 140 are each equipped with a plug (not shown in the figure). When air, liquid, or gas needs to be introduced, the plug is removed. After the air, liquid, or gas is introduced, the plug can be reinserted to avoid long-term contact with the external environment, which could interfere with the circulation of the oil-gas mixture.

[0029] The first direction baffle assembly 200 includes a baffle 210, a longitudinal plate 220, and an annular segment 230. The baffle 210 and the longitudinal plate 220 are perpendicular to each other and fixedly connected. There is a flow space 201 between the longitudinal plate 220 and the annular segment 230 so that a portion of the oil-gas mixture can flow directly through the flow space 201. The two ends of the annular segment 230 are fixedly connected to the baffle 210 and the longitudinal plate 220 at their joints, respectively. The outer periphery of the baffle 210 abuts against the inner wall of the tower body 101 and is fixedly connected to the inner wall of the tower body 101. The outer periphery of the annular segment 230 abuts against the inner wall of the tower body 101 and is fixedly connected to the inner wall of the tower body 101.

[0030] The partition 210 has multiple flow holes 211, with a gap between adjacent flow holes 211, so that a portion of the oil-gas mixture can also flow through the flow holes 211.

[0031] The first direction partition assembly 200 is preferably made of a corrosion-resistant material.

[0032] It is worth mentioning that the specific components and other technical features of the corrosion-resistant materials involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be conventionally selected in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not elaborate further.

[0033] For those skilled in the art, modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
