Description

Technical Field

[0001] The utility model relates to the technical field of distillation columns, and more specifically, the utility model relates to a distillation column facilitating the cleaning of the inner wall. Background Art

[0002] A distillation column is a tower-type gas-liquid contact device. Distillation is a method of separating different components in a mixture by utilizing the different volatilities of each component in the mixture. A traditional distillation column is composed of components such as a tower body, an inlet gas pipe, an outlet gas pipe, an inlet liquid pipe, an outlet liquid pipe, and tower plates. The mixture solution is poured into the top of the distillation column, while the gas is poured into the bottom of the distillation column. Gas channels are provided on the tower plates, and a cover is arranged at the top of the air hole channels, forming a water seal structure with the gas channels. The gas passes through the gas channels on the tower plates. During the contact process of the liquid and the gas, the components in the mixture are separated. However, during the operation of the distillation column, the inner wall of the distillation column is soaked in the liquid for a long time, and the solute in the liquid will gradually deposit on the inner wall of the distillation column, thus forming dirt. The traditional method for cleaning the distillation column is to use a cleaning solution or high-pressure water flushing, and the cleaning effect is poor, making it difficult to remove stubborn dirt. To solve the deficiencies of the prior art, we propose a distillation column facilitating the cleaning of the inner wall. Summary of the Utility Model

A sealing plate 58 is fixedly connected to the top surface of the sliding frame 55.

[0022] Among them, the sealing plate 58 is located directly below the vertical air pipe 53, and the sealing plate 58 is used to seal the air outlet of the vertical air pipe 53;

[0025] The sliding frame 55 is restricted by the vertical guide rod 54 to move only up and down along the vertical guide rod 54. When the air pump 51 conveys air into the vertical air pipe 53, it will push the sealing plate 58 and the sliding frame 55 downward. Then, under the action of the spring 57, the sliding frame 55 and the sealing plate 58 will be pushed upward, causing the sliding frame 55 and the brush 56 to move up and down repeatedly to wash the inner wall of the tower body 1.

[0026] Among them, the cover cleaning assembly 6 includes a baffle 61, which is fixedly installed on the outer surface of one side of one of the tower plates 2. A first rotating shaft 62 is rotatably connected to the inner wall of the baffle 61. One end of the first rotating shaft 62 is fixedly connected with a first fan blade 63. A diversion groove 64 is fixedly installed on the top of the baffle 61. A first bevel gear 65 is fixedly connected to the outer wall of the first rotating shaft 62.

When the rectifying column is working, gas continuously flows upward from the bottom through multiple gas channels 3, thereby driving the second fan blade 68 to rotate. Under the dual power of the first fan blade 63 and the second fan blade 68, it drives the scraper 69 to rotate around the second rotating shaft 66, thereby cleaning the inner wall of the cover component 4.

The sliding frame 55 and the brush 56 move downward along the vertical guide rod 54. Under the thrust of the spring 57, the sliding frame 55 and the brush 56 quickly move upward again. Under the repeated pushing of the air and the spring 57, it drives the sliding frame 55 and the brush 56 to move up and down reciprocally, cooperating with the cleaning liquid to clean the inner wall of the tower body 1. When the rectifying column is working, liquid continuously flows into the upper part of the first fan blade 63 from the diversion groove 64, driving the first fan blade 63 to rotate. The first fan blade 63 transmits power to the second rotating shaft 66 through the first bevel gear 65 and the second bevel gear 67.
