With the continuous expansion of global industrial production scale and the increasing requirements for product quality, the application of distillation technology is becoming more and more widespread, and higher standards are being set for the performance of distillation columns.

[0003] In the existing technology, compound distillation columns are widely used in the industrial field. During long-term use, solid particles in the material can clog the packing layer inside the compound distillation column. Traditionally, the packing layer needs to be disassembled, cleaned and reinstalled, which reduces the cleaning efficiency of the packing layer and increases the labor intensity of the workers.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1: As Figures 1-4 As shown, this utility model provides a composite distillation column, including a cleaning mechanism 1, and a main body 2 is provided on the top of the cleaning mechanism 1;

[0026] The cleaning mechanism 1 includes a base plate 11, a heating box 14 fixedly installed on the top of the base plate 11, a heating tube 141 provided on the inner wall of the heating box 14, a top plate 15 fixedly installed on the top of the heating box 14, a power supply 151 fixedly installed on the top of the top plate 15, the outer wall of the power supply 151 is fixedly connected to the outer wall of the heating tube 141, a data acquisition device 152 is fixedly inserted into the inner wall of the top plate 15, and a fixing groove 153 is opened on the top of the top plate 15. The main body mechanism 2 includes a support frame 21 and two air outlet pipes 25, a conveying pipe 26 is fixedly connected between the outer walls of the two air outlet pipes 25, and a second valve 261 is provided on the inner wall of the conveying pipe 26.

[0027] The overall effect of Embodiment 1 is that after the composite distillation column completes the processing of the material, the remaining water from the composite distillation column is transported to the heating chamber 14 through operator intervention and the cooperation of other structures. Then, the water inside the heating chamber 14 is heated by the power supply 151 and the heating tube 141. Simultaneously, the temperature and pressure of the water vapor inside the heating chamber 14 are monitored in real time by the data acquisition device 152 (temperature sensor and pressure sensor). When the temperature and pressure of the water vapor inside the heating chamber 14 reach suitable values, the water is heated... Under the operation of the staff, the second valve 261 is opened, allowing high-temperature and high-pressure water vapor to be sprayed out from the outlet pipe 25 through the conveying pipe 26. This high-pressure removal of the blockages blocking the first packing layer 23 and the second packing layer 24 causes them to fall off. After a certain period of spraying, the second valve 261 is closed. Then, under the operation of the staff, the sealing cover at the designated position of the composite distillation column is opened, making it easier to collect and remove the fallen blockages. This avoids the need to disassemble and clean the first packing layer 23 and the second packing layer 24, greatly improving the cleaning efficiency.

[0028] Example 2: As Figures 2-4As shown, a filter box 12 is fixedly installed on the top of the base plate 11. A circular groove 121 is formed on one side of the outer wall of the filter box 12. Three sets of insertion slots 122 are formed on the inner surface of the filter box 12. Filter plates 123 are movably inserted between the inner surface of the three sets of insertion slots 122. A top cover 124 is fixedly installed on the top of the filter box 12 by bolts. A connecting pipe 13 is fixedly connected to one side of the outer wall of the filter box 12, and one side of the outer wall of the connecting pipe 13 is fixedly connected to one side of the outer wall of the heating box 14. A delivery pump 131 is fixedly installed on the top of the base plate 11, and the outer wall of the delivery pump 131 is fixedly connected to the outer wall of the connecting pipe 13. A tower body 22 is fixedly installed on the inner wall of the support frame 21. A water supply pipe 221 is fixedly connected to the bottom of the tower body 22. A first valve 222 is provided on the inner wall of the water supply pipe 221. A first packing layer 23 and a second packing layer 24 are fixedly installed on the inner wall of the tower body 22. The outer walls of the two air outlet pipes 25 are both located inside the first packing layer 23 and the second packing layer 24. The top of the bottom plate 11 is fixedly connected to the bottom of the support frame 21. The outer wall of the water supply pipe 221 is fixedly inserted into the inside of the circular groove 121. The outer wall of the conveying pipe 26 is fixedly inserted into the inside of the fixed groove 153.

[0029] The overall effect of Embodiment 2 is that when it is necessary to clean the first packing layer 23 and the second packing layer 24 inside the composite distillation column, the first valve 222 is opened under the operation of the operator, so that the water remaining after processing inside the composite distillation column is transported from the water supply pipe 221 to the filter box 12. Under the action of the filter plate 123 (primary filter plate and magnetic filter plate) inside, particulate impurities and metal impurities in the water can be filtered and adsorbed, so as to avoid the impurities from damaging the subsequent delivery pump 131. The filtered water can be transported to the heating box 14 for use by the delivery pump 131 and the connecting pipe 13, thereby improving the utilization rate of water resources and avoiding the waste of water resources.

[0030] Working Principle: After the composite distillation column completes the processing of materials, it needs to clean its first packing layer 23 and second packing layer 24. Under the operator's control, the first valve 222 is opened, allowing the remaining water from the composite distillation column to be transported through the water supply pipe 221 to the filter box 12. The filter plates 123 (primary filter plate and magnetic filter plate) inside the filter box 12 filter and adsorb particulate and metallic impurities in the water, preventing damage to the subsequent transfer pump 131. The filtered water is then transported to the heating box 14 by the transfer pump 131 and connecting pipe 13. Finally, the water inside the heating box 14 is heated by the power supply 151 and heating pipe 141. Simultaneously, with the help of the data acquisition device 152 (temperature sensor and pressure sensor), the temperature and pressure of the water vapor inside the heating box 14 can be monitored in real time. When the temperature and pressure of the water vapor inside the heating box 14 reach a suitable value, the second valve 261 is opened under the operation of the operator, so that the high-temperature and high-pressure water vapor is sprayed out from the outlet pipe 25 through the delivery pipe 26, thereby removing the blockages blocking the first packing layer 23 and the second packing layer 24 under high pressure and causing them to fall off from the first packing layer 23 and the second packing layer 24. After a certain period of spraying, the second valve 261 is closed, and then the sealing cover at the designated position of the composite distillation column is opened under the operation of the operator, so as to facilitate the collection and removal of the fallen blockages.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
