Description

Technical Field

[0001] The utility model relates to the technical field of distillation columns, and specifically relates to a distillation column with uniform packing. Background Art

[0002] A distillation column is a mass transfer and heat transfer device widely used in petrochemical production, and is also a tower-type vapor-liquid contact device for distillation. The distillation column can utilize the different volatilities of each component in the mixture, that is, the vapor pressures of each component are different at the same temperature. This property enables the light components in the liquid phase to transfer to the gas phase, while the heavy components in the gas phase transfer to the liquid phase, thereby achieving the purpose of separation.

[0003] However, the existing distillation columns still have some disadvantages in actual use: Although the existing distillation columns can place packing materials of different materials into the tower body from the feed port for reaction separation operations, the packing placed into the distillation column will accumulate in the packing layer and cannot be evenly discharged. As a result, the liquid and the packing cannot fully react, affecting the efficiency during the operation. For a few distillation columns that can rotate and evenly spread the packing materials, they are prone to spraying and adhering to the side wall of the distillation column due to too fast rotation speed during the rotation and spreading, thus easily corroding the inner wall.

[0004] Therefore, we designed a distillation column with uniform packing to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a distillation column with uniform packing to solve the problems raised in the above background art.

[0006] To solve the above technical problems, a distillation column with uniform packing provided by the utility model includes a base, a tower body is fixedly arranged on the base, a support grid is fixedly arranged inside the tower body, a packing layer is arranged on the support grid, a filter plate is movably arranged above the support grid, a lead screw is rotatably arranged inside the filter plate, a nut is threadedly sleeved on the lead screw, a scraper is fixedly arranged on the nut, the scraper is slidably arranged inside the tower body, a placement cavity is further opened inside the filter plate, a motor is fixedly arranged inside the placement cavity, and the driving end of the motor is in transmission connection with one end of the lead screw. An inlet part is further arranged on the tower body.

[0007] Furthermore, a partition is fixedly arranged inside the scraper, two springs are symmetrically arranged inside the scraper, the two springs are respectively fixedly arranged on both sides of the partition, a telescopic plate is movably arranged inside the scraper, the other end of the spring is fixedly connected to the telescopic plate, and the telescopic plate abuts against the side wall of the packing layer. The scraper and the telescopic plate can flatten the bulging packing, making the packing arrangement uniform.

[0008] Furthermore, a cavity is formed inside the scraper, and sliding openings are formed on both sides of the scraper. The cavity communicates with the sliding openings. The telescopic plate is slidably inserted into the sliding openings, and the partition plate is fixedly installed inside the cavity. The arrangement of the sliding openings can better enable the telescopic plate to slide in the sliding openings, avoiding the problem of movement interference.

[0009] Furthermore, two limit blocks are symmetrically and fixedly installed on the top of the filter plate. A cylinder is fixedly arranged on the inner top wall of the limit block. The driving end of the cylinder penetrates through the limit block and is fixedly connected to the filter plate. The filter plate is slidably arranged in the packing layer. The arrangement of the cylinder enables the scraper to touch the unevenly laid packing due to the cooperation of the cylinder to make the horizontal plane of the packing flush, and can also finally drive the filter plate to press down and squeeze the space above the packing layer, avoiding a large gap between the gas, liquid and the packing during the separation operation, so that the packing shakes up and down in the packing layer and impacts the bottom of the filter plate, causing certain damage to the filter plate.

[0010] Furthermore, the feeding member includes a feeding port, which is fixedly inserted into the side wall of the tower body and communicates with the packing layer. The feeding port is located obliquely above the packing layer. The arrangement of the feeding port can facilitate feeding into the packing layer more conveniently.

[0011] Furthermore, a liquid inlet pipe is fixedly arranged at the top of one side of the tower body. A spray head is fixedly installed at one end of the liquid inlet pipe for spraying liquid. The arrangement of the liquid inlet pipe can better cooperate with the spray head for spraying operation.

[0012] Furthermore, a liquid redistributor is fixedly arranged at the bottom of the support grid. A liquid guide pipe is also fixedly inserted into one side of the tower body. The other end of the liquid guide pipe is fixedly connected to a liquid collecting tank. The arrangement of the liquid guide pipe can collect the finally redundant liquid into the liquid collecting tank through the liquid guide pipe.

[0013] Furthermore, a liquid guide inclined plate is also fixedly arranged on the inner bottom wall of the tower body. The arrangement of the liquid guide inclined plate can better assist the liquid guide pipe in collecting liquid, making the collection efficiency higher.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows: The driving end of the motor drives the lead screw to make the scraper slide in the packing layer. During the sliding process of the packing layer, both ends of the telescopic plate always abut against the inner wall of the tower body. The telescopic plate cooperates with the scraper to make the spring compress and rebound according to the diameters at different positions inside the tower body, controlling the length of the telescopic plate extending out, and can better perform the uniform paving operation.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: The air cylinder can cooperate with the scraper, enabling the scraper to reciprocate and evenly spread while descending to level the horizontal plane of the filler, enhancing the even spreading effect of the scraper. The air cylinder can also press down the filter plate and squeeze the space above the filler layer, avoiding a large gap between the gas, liquid and the filler during the separation operation, which may cause the filler to shake up and down in the filler layer and impact the bottom of the filter plate, causing certain damage to the filter plate.

[0026] The inlet part includes an inlet port 17, the inlet port 17 is fixedly inserted into the side wall of the tower body 2 and communicates with the packing layer 4, and the inlet port 17 is located obliquely above the packing layer 4.

[0027] During specific implementation, the packing is conveyed from the inlet port 17 into the packing layer 4, the driving end of the motor 8 drives the lead screw 5 to make the scraper 9 slide inside the packing layer 4. During the sliding process of the packing layer 4, both ends of the telescopic plate 12 always abut against the inner wall of the tower body 2. The telescopic plate 12 cooperates with the scraper 9 to control the length of the telescopic plate 12 extended by the compression and rebound of the spring 13 according to the diameters at different positions inside the tower body 2, so as to better perform the uniform paving operation.

[0028] Refer to Figures 1-5 As shown, two limiting blocks 15 are symmetrically and fixedly installed on the top of the filter plate 3, a cylinder 16 is fixedly arranged on the inner top wall of the limiting block 15, the driving end of the cylinder 16 penetrates through the limiting block 15 and is fixedly connected to the filter plate 3, and the filter plate 3 is slidably arranged inside the packing layer 4.

[0029] During specific implementation, the driving end of the cylinder 16 drives the scraper 9 to make the scraper 9 reciprocate and uniformly pave while descending to make the horizontal plane of the packing flush, enhancing the uniform paving effect of the scraper 9. The cylinder 16 can also drive the filter plate 3 to press down and squeeze the space above the packing layer 4, which can avoid large gaps between the gas, liquid and the packing during the separation operation, so that the packing shakes up and down inside the packing layer 4 and impacts the bottom of the filter plate 3, causing certain damage to the filter plate 3.

[0030] Refer toFigures 1-5 On one side of the top of the tower body 2, a liquid inlet pipe 18 is fixedly arranged. One end of the liquid inlet pipe 18 is fixedly installed with a spray head for spraying liquid. The arrangement of the liquid inlet pipe 18 can better cooperate with the spray head for spraying operation.

[0031] Refer to Figures 1-5 At the bottom of the support grid 20, a liquid redistributor 19 is fixedly arranged. On one side of the tower body 2, a liquid guide pipe 22 is also fixedly inserted. The other end of the liquid guide pipe 22 is fixedly connected to a liquid collection tank 23. The arrangement of the liquid guide pipe 22 can collect the finally redundant liquid into the liquid collection tank 23 through the liquid guide pipe 22.

[0032] Refer to Figures 1-5 On the inner bottom wall of the tower body 2, a liquid guide inclined plate 21 is also fixedly arranged. The arrangement of the liquid guide inclined plate 21 can better assist the liquid guide pipe 22 in collecting liquid, making the collection efficiency higher.

[0033] In addition, it should be noted that an air inlet is arranged above the liquid guide pipe 22 to facilitate the separation operation of the mutual cooperation of liquid, gas and solid packing.

[0034] Working principle: The external power supply enables the electrical appliances to operate normally. Before the separation operation, packing is conveyed into the packing layer 4 through the feed inlet 17. At this time, the motor 8 and the cylinder 16 are started simultaneously. The driving end of the motor 8 drives the lead screw 5 to rotate, so that the nut 6 drives the scraper 9 to slide in the packing layer 4. During the sliding process, the cylinder 16 also drives the filter plate 3 to slowly descend, so that the scraper 9 touches the unevenly laid packing due to the cooperation of the cylinder 16 to make the horizontal plane of the packing flat. During the sliding process, both ends of the scraper 9 are always in contact with the inner wall of the tower body 2. When the scraper 9 moves to the widest part inside the tower body 2, the spring 13 rebounds and pushes the telescopic plate 12 to extend towards both sides of the scraper 9 for uniform paving operation. When the scraper 9 slides to both sides of the packing layer 4, due to the smaller diameter, the spring 13 is compressed by the resisting force and retracts the sliding port 14 into the cavity 10. The compression and rebound of the spring 13 due to the change in position enable the telescopic plate 12 to slide in the sliding port 14 to better uniformly pave the packing;

[0035] After uniform paving, the driving end of the cylinder 16 drives the filter plate 3 to press down and squeeze the space above the packing layer 4, which can avoid large gaps between the gas, liquid and packing during the separation operation, so that the packing shakes up and down in the packing layer 4 and impacts the bottom of the filter plate 3, causing certain damage to the filter plate 3.
