Abstract
Description
Technical Field
[0001] This utility model relates to the field of distillation column cleaning, and more specifically, it relates to a distillation column with a self-cleaning function. Background Technology
[0002] Distillation towers are chemical equipment made of rare metals such as titanium and their alloys. They have the characteristics of high strength, high toughness, high temperature resistance, corrosion resistance, and light weight. In chemical production, distillation towers are often used for separation and purification. Distillation towers are mainly divided into two types: plate towers and packed towers.
[0003] When cleaning a plate column, a high-speed, reverse fluid pulse is usually introduced into the plate system periodically or continuously. The backflow instantly reverses the normal flow direction and forcefully flushes away the blockages deposited on the plate system. However, this method can only clear the bubble caps and sieve holes, and the cleaning effect on the plate body is poor. The dirt deposited on the plate body will obstruct the liquid flow, which will lead to a significant decrease in the processing efficiency of the distillation column.
[0004] Therefore, a new solution is needed to address this problem. Utility Model Content
[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a distillation column with a self-cleaning function. During cleaning, a cleaning solution is sprayed into the distillation column through a spray assembly. Subsequently, a drive component drives the baffle to slide, allowing the cleaning solution to flow downwards and be quickly discharged to avoid residue. This process cleans the column plate body and restores the distillation column's processing efficiency to its initial state.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a distillation column with self-cleaning function includes a column body, a plurality of column plates fixedly connected inside the column body, a plurality of bubble caps fixedly connected to the column plates, baffles slidably connected to the column plates, a driving component for driving the baffles to slide on the column plates, and a spray assembly for cleaning the column plates on the column body.
[0007] The present invention is further configured such that: the driving component includes an electric push rod fixedly connected to the bottom side of the tower plate, a fixed plate fixedly connected to the telescopic end of the electric push rod, and an extension rod fixedly connected to the fixed plate, wherein the extension rod is fixedly connected to an adjacent baffle.
[0008] The present invention is further configured such that all of the aforementioned tower plates are inclined.
[0009] The present invention is further configured such that: the spray assembly includes a plurality of water supply pipes fixedly connected to the tower body, a spray frame fixedly connected to one end of the water supply pipe inside the tower body, a connecting pipe fixedly connected to the other end of the water supply pipe, a main pipe fixedly connected between the plurality of connecting pipes, and a connector fixedly connected to the main pipe, and the plurality of spray frames are respectively located on the upper side of a plurality of tower plates.
[0010] The present invention is further configured such that: a plurality of stabilizing rods are fixedly connected between the plurality of connecting pipes, and the stabilizing rods are fixedly connected to the tower body.
[0011] The present invention is further configured such that: a connecting frame is fixedly connected to the telescopic end of the electric push rod, a plurality of spring telescopic rods are fixedly connected to the connecting frame, and a top block is fixedly connected to the other end of the spring telescopic rods.
[0012] In summary, this utility model has the following beneficial effects: during cleaning, the cleaning liquid can be sprayed into the distillation column through the spray assembly, and then the electric push rod drives the baffle to slide, so that the cleaning liquid flows downward and is discharged quickly, thereby cleaning the column plate body and restoring the processing efficiency of the distillation column to its initial state. In addition, a top block is provided to knock on the bottom of the column plate during cleaning, so that the column plate vibrates and further improves the cleaning effect.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0019] A distillation column with self-cleaning function, such as Figures 1-4As shown, the system includes a tower body 1, with several tower plates 2 fixedly connected inside the tower body 1. Several bubble caps 3 are fixedly connected to the tower plates 2, and baffles 4 are slidably connected to the tower plates 2. The tower plates 2 are equipped with a driving component for driving the baffles 4 to slide. The tower body 1 is equipped with a spray assembly for cleaning the tower plates 2. The driving component includes an electric push rod 5 fixedly connected to the bottom side of the tower plates 2, a fixed plate 6 fixedly connected to the telescopic end of the electric push rod 5, and an extension rod 7 fixedly connected to the fixed plate 6. Fixing the electric push rod 5 to the bottom side of the tower plates 2 can prevent the electric push rod 5 from being corroded by prolonged contact with the liquid. The extension rod 7 is fixedly connected to the adjacent baffles 4. The tower plates 2 are all inclined. When the tower plates 2 are inclined towards the notch, the cleaning liquid can flow down quickly, preventing the cleaning liquid from remaining on the tower plates 2.
[0020] like Figures 1-4 As shown, when the distillation column needs to be cleaned, the cleaning liquid can first be sprayed onto the tray 2 through the spray assembly. Then, wait for the dirt to react fully with the cleaning liquid and fall off. Next, start the electric push rod 5 to extend and drive the fixed plate 6 and the extension rod 7 to move closer to the bottom of the column body 1. At this time, the baffle 4 will also be driven by the extension rod 7 to move closer to the bottom of the column body 1. The cleaning liquid and dirt mixed in the cleaning liquid that are stuck on the upper side of the tray 2 will flow down from the tray 2 to the next tray 2. At this time, the baffle 4 on the next tray 2 will not block the cleaning liquid. The cleaning liquid and dirt mixed in the cleaning liquid on the next tray 2 will also flow downward. When the cleaning liquid on several trays 2 has flowed down, the discharge pipe on the column body 1 can be opened to discharge the cleaning liquid and dirt mixed in the cleaning liquid. In this way, the tray 2 can be cleaned and the cleaning liquid residue can be avoided, so that the processing efficiency of the distillation column can be restored to the initial state.
[0021] like Figures 1-3 As shown, the spray assembly includes several water supply pipes 8 fixedly connected to the tower body 1, spray frames 9 fixedly connected to one end of the water supply pipes 8 inside the tower body 1, connecting pipes 10 fixedly connected to the other end of the water supply pipes 8, main pipes 11 fixedly connected among the several connecting pipes 10, and connectors 12 fixedly connected to the main pipes 11. The several spray frames 9 are respectively located on the upper side of several tower plates 2, and all spray frames 9 are located on the lower side of the tower plates 2, which can prevent the spray frames 9 from being corroded by prolonged contact with liquid.
[0022] like Figures 1-3As shown, when the spray assembly needs to be turned on, the external cleaning fluid delivery pipe can be connected to the connector 12 first, and then the external cleaning fluid delivery pipe can be turned on. The cleaning fluid will first enter the inner main pipe 11, and then be dispersed from the main pipe 11 to each connecting pipe 10, and finally enter the water supply pipe 8 and be sprayed out from the spray frame 9. Then the cleaning fluid will be retained on the upper side of the tower plate 2 due to the baffle 4. When the cleaning fluid water level line on the upper side of the tower plate 2 is level with the baffle 4, the external cleaning fluid delivery pipe can be turned off. Then wait for the cleaning fluid to react with the dirt. At the same time, some of the cleaning fluid sprayed out by the spray frame 9 will spray and rinse the bottom side of the tower plate 2, and rinse the small amount of deposits on the bottom side of the tower plate 2.
[0023] like Figure 1 As shown, several stabilizing rods 13 are fixedly connected between several connecting pipes 10. The stabilizing rods 13 are fixedly connected to the tower body 1, which can support and stabilize the several connecting pipes 10, prevent the connecting pipes 10 from shaking when conveying cleaning fluid, and prevent the connecting pipes 10 from being damaged after long-term operation.
[0024] like Figures 3-4 As shown, the telescopic end of the electric push rod 5 is fixedly connected to a connecting frame 14, and several spring telescopic rods 15 are fixedly connected to the connecting frame 14. The other end of the spring telescopic rod 15 is fixedly connected to a top block 16. When the baffle 4 is driven by the electric push rod 5 and no longer blocks the downward flow of the cleaning liquid remaining on the upper side of the tray 2, the spring telescopic rod 15 is in normal state. At this time, the electric push rod 5 can be restarted to extend one end distance, and then the electric push rod 5 can be restarted to retract. At this time, the top block 16 will contact and impact the bottom side of the tray 2. By repeating this process, the tray 2 can be vibrated. At this time, the external cleaning liquid delivery pipe can be opened to spray the cleaning liquid again, which can remove the stubborn dirt remaining on the upper side of the tray 2.
[0025] Working principle: When cleaning the distillation column is required, first connect the external cleaning liquid delivery pipe to connector 12, then open the external cleaning liquid delivery pipe. The cleaning liquid will first enter the inner main pipe 11, then disperse from the main pipe 11 to each connecting pipe 10, and finally enter the water delivery pipe 8 and be sprayed out from the spray frame 9. Subsequently, the cleaning liquid will be retained on the upper side of the tower plate 2 due to the baffle 4. When the cleaning liquid level on the upper side of the tower plate 2 is level with the baffle 4, the external cleaning liquid delivery pipe can be closed. Then wait for the dirt and cleaning liquid to fully react and fall off. Next, start the electric push rod 5 to extend and drive the fixed plate 6 and extension rod 7 to move closer to the bottom of the tower body 1. At this time, the baffle 4 will also be driven by the extension rod 7 to move closer to the bottom of the tower body 1. At this time, the cleaning liquid retained on the upper side of the tower plate 2 and the dirt mixed in the cleaning liquid will be removed. The cleaning liquid flows down from tray 2 to the next tray 2. At this time, the baffle 4 on the next tray 2 will not block the cleaning liquid. The cleaning liquid and the dirt mixed in the cleaning liquid on the next tray 2 will also flow downward. When the cleaning liquid on several trays 2 has flowed down, the discharge pipe on the column body 1 can be opened to discharge the cleaning liquid and the dirt mixed in the cleaning liquid. Then, the electric push rod 5 can be activated again to extend one end of the distance, and then the electric push rod 5 can be activated again to retract. At this time, the top block 16 will contact and impact the bottom side of the tray 2. This repetition will make the tray 2 vibrate. Then, the external cleaning liquid delivery pipe can be opened again to spray the cleaning liquid, which can remove the stubborn dirt remaining on the upper side of the tray 2. In this way, the tray 2 can be cleaned and the cleaning liquid residue can be avoided, so that the processing efficiency of the distillation column can be restored to the initial state.
