Description

Technical Field

[0001] This utility model relates to the field of distillation equipment technology, and in particular to a convenient tower distillation device. Background Technology

[0002] Distillation is a thermodynamic separation process that utilizes the different boiling points of components in a liquid mixture or liquid-solid system. It involves evaporating the lower-boiling-point component and then condensing it to separate the entire component. It is a unit operation combining evaporation and condensation. Compared to other separation methods such as extraction, filtration, and crystallization, its advantage lies in the fact that it does not require the use of solvents other than those used in the system, thus ensuring that no new impurities are introduced.

[0003] However, existing distillation equipment is prone to the problem of repeated distillation, that is, when the vapor at the bottom leaves upward, it is condensed by the liquid inlet at the top, resulting in low distillation efficiency and increased production costs. Utility Model Content

[0004] The purpose of this invention is to provide a convenient tower distillation device that reduces the possibility of vapor being re-condensed when it rises, thereby improving distillation efficiency and reducing production costs.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A convenient tower distillation device includes a tower body, which is equipped with a heating device and a liquid guiding device. The upper end of the tower body is provided with a liquid inlet pipe and a vapor pipe, and the lower end is provided with a discharge pipe. The liquid in the liquid inlet pipe flows into the liquid guiding device, which includes a number of vertically distributed guiding plates with adjacent guiding plates connected to each other. There is a gap between the outer periphery of the guiding plates and the interior of the tower body. The liquid flows continuously downward along the guiding plates and is finally discharged from the discharge pipe. A hollow heat insulation layer is also provided below the guiding plates, and the heating device is located in or connected to each hollow heat insulation layer.

[0007] By adopting the above technical solution, the liquid flows continuously downward along the guide plate and is eventually discharged from the discharge pipe. During the process, the heating device is located or connected to each hollow insulation layer. While heating and evaporating the liquid on the guide plate, it also allows the vapor below to directly encounter the hollow insulation layer instead of the guide plate when it rises. This avoids the problem of re-condensation when it comes into contact with the guide plate cooled by the liquid, thus improving distillation efficiency and reducing production costs.

[0008] Furthermore, the liquid guiding device includes a hollow column in the middle, a heating device located in or connected to the hollow column, and a plurality of first through holes distributed vertically on the outer periphery of the hollow column, the first through holes being connected to the corresponding hollow insulation layer.

[0009] By adopting the above technical solution, the hollow column is connected to the corresponding hollow insulation layer through the first through hole, so that the heating device can heat different hollow insulation layers and improve the distillation efficiency.

[0010] Furthermore, the flow guide plate includes at least one spiral segment, which is connected downward to the next flow guide plate.

[0011] By adopting the above technical solution, the spiral guide facilitates the stable and uniform downward flow of liquid, further improving the distillation effect.

[0012] Furthermore, several second through holes are opened on the lower side of the hollow insulation layer, with the second through holes facing the downward-facing guide plate.

[0013] By adopting the above technical solution, with the second through hole facing the downward guide plate, the heating device can heat and evaporate the liquid on the guide plate through each hollow heat insulation layer, while also blowing the liquid on the lower guide plate downward to accelerate evaporation.

[0014] Furthermore, the flow guide plate is provided with several flow-blocking strips.

[0015] By adopting the above technical solution, the liquid flow rate on the guide plate is further reduced, thereby improving the distillation effect.

[0016] Furthermore, one end of the flow-blocking strip is connected to the outer or inner ring of the flow guide plate, and the other end is spaced apart from the inner or outer ring of the flow guide plate.

[0017] By adopting the above technical solution, the liquid is bypassed at one end and passes through the other end, guiding the liquid's movement path to be longer and improving the distillation effect.

[0018] Furthermore, the adjacent flow-blocking strips are respectively connected to the outer and inner rings of the flow-guiding disc body.

[0019] By adopting the above technical solution, the liquid on the guide plate can spiral down along an S-shaped trajectory, further increasing the length of the liquid movement path and improving the distillation effect.

[0020] Furthermore, the flow-blocking strip is inclined, with one end high and connected to the outer or inner ring of the flow guide plate, and the other end gradually decreasing in height and having a gap between it and the inner or outer ring of the flow guide plate.

[0021] By adopting the above technical solution, the liquid movement path is guided while avoiding excessive backflow and reducing splashing, making the liquid movement smoother.

[0022] In summary, this utility model has the following beneficial effects:

[0023] The liquid flows continuously downward along the guide plate and is eventually discharged from the discharge pipe. During the process, the heating device is connected to each hollow insulation layer. While heating and evaporating the liquid on the guide plate, it also allows the vapor below to directly encounter the hollow insulation layer instead of the guide plate when it rises. This avoids the problem of re-condensation when it comes into contact with the guide plate cooled by the liquid, thus improving distillation efficiency and reducing production costs.

[0024] The hollow column is connected to the corresponding hollow insulation layer through the first through hole, allowing the heating device to heat different hollow insulation layers and improve distillation efficiency. The spiral section of the guide plate facilitates stable and uniform downward flow of liquid. The second through hole faces the downward guide plate, allowing the heating device to heat and evaporate the liquid on the guide plate through each hollow insulation layer while simultaneously blowing the liquid downwards onto the lower guide plate to accelerate evaporation. The flow-blocking strip further reduces the liquid flow velocity on the guide plate, allowing the liquid to spiral down along an S-shaped trajectory, further increasing the length of the liquid movement path and improving the distillation effect.

[0030] A user-friendly column distillation apparatus, such as Figure 1As shown, the system includes a tower body 1, which contains a heating device 2 and a liquid guiding device. The upper end of the tower body 1 has an inlet pipe 11 and a steam pipe 12, and the lower end has a discharge pipe 13. The portion of the inlet pipe 11 inside the tower body 1 is fitted with a heat-insulating sleeve. The liquid in the inlet pipe 11 flows into the liquid guiding device, which includes several vertically distributed guide plates 3, with adjacent guide plates 3 interconnected. The outer periphery of each guide plate 3 is spaced from the interior of the tower body 1. The liquid flows continuously downwards along the guide plates 3 and is finally discharged from the discharge pipe 13.

[0031] A hollow insulation layer 31 is also provided below the guide plate body 3. The heating device 2 is located in or connected to each hollow insulation layer 31 to heat the flowing liquid and make the steam leave through the steam pipe 12 through the gap between the outer periphery of the guide plate body 3 and the interior of the tower body 1, and enter the next step of condensation and other operations.

[0032] The guide plate 3 includes at least one spiral segment, which is connected downward to the next guide plate 3. In this embodiment, the guide plate 3 is spiral in shape and connected vertically to form a whole. An upward baffle is provided on its outer periphery to prevent the liquid from leaving. In this embodiment, the outer side of the baffle is the same hollow heat insulation layer 31.

[0033] like Figure 1 As shown, the liquid guiding device includes a hollow column 4 in the middle, a guiding plate 3 fixed on the outer periphery of the guiding plate 3, and a heating device 2 including a heating rod connected to the hollow column 4. The top of the hollow column 4 is closed, and the lower outer periphery is also connected to the air inlet pipe 42. The air inlet pipe 42 is connected to the air inlet fan, so that cold air or preheated air enters and is heated by the heating rod, which drives the gas in the tower body 1 to flow. For example, in some embodiments, the air inlet pipe exchanges heat with the steam pipe 12 through a heat exchange device before being introduced into the hollow column 4.

[0034] In this embodiment, the air inlet pipe is L-shaped, with the horizontal end connected to the external fan and the vertical end sleeved on the heating rod. There is a gap between the upper end and the top of the hollow column 4, so that the air is fully heated before entering the hollow column 4 and finally entering the tower body 1. Specifically, several first through holes 41 are opened on the outer periphery of the hollow column 4, which are distributed vertically. The first through holes 41 are connected to the corresponding hollow insulation layer 31. Several second through holes 311 are opened on the lower side of the hollow insulation layer 31, and the second through holes 311 face the downward guide plate 3.

[0035] like Figure 2 As shown, in some embodiments, the flow guide plate 3 is provided with a plurality of flow-blocking strips 32; one end of the flow-blocking strip 32 is connected to the outer or inner ring of the flow guide plate 3, and the other end is spaced apart from the inner or outer ring of the flow guide plate 3; in this embodiment, adjacent flow-blocking strips 32 are respectively connected to the outer and inner rings of the flow guide plate 3, so that the liquid on the flow guide plate 3 can spiral down along an S-shaped trajectory, thereby increasing the length of the liquid movement path;

[0036] In this embodiment, the flow-blocking strip 32 is inclined, with one end high and connected to the outer or inner ring of the flow guide plate 3, and the other end gradually decreasing in height and having a gap between it and the inner or outer ring of the flow guide plate 3, so that the liquid moves more smoothly.
