Description

Technical Field

[0001] This utility model relates to the field of distillation column technology, specifically to a high-efficiency and energy-saving distillation column with a protective mechanism. Background Technology

[0002] High-efficiency and energy-saving distillation columns are distillation equipment that significantly reduces energy consumption and improves separation efficiency by integrating advanced heat recovery technology, optimized structural design and intelligent control system. They utilize the property that the components in a mixture have different volatility, that is, different vapor pressures of the components at the same temperature, to transfer the lighter components in the liquid phase to the gas phase, while the heavier components in the gas phase are transferred to the liquid phase, thereby achieving the purpose of separation.

[0003] The utility model CN221557571U discloses a distillation column with a protective mechanism, including a protective shell, a distillation column body and a fixing assembly. The distillation column body is disposed inside the protective shell. Four connecting rods are welded on the distillation column body. Each of the four connecting rods is provided with a fixing assembly. The fixing assembly includes an arc plate, an annular cavity, a liquid storage tank, a slider, a threaded rod, a rotating plate and a seal.

[0004] The above technical solution, through the cooperation of various components, can achieve fixed installation of distillation columns of different sizes. It is not only simple in structure but also easy to disassemble, improving practicality and convenience. However, the feed inlet does not have a filter protection structure to reduce particulate matter clogging the pipe. Furthermore, prolonged high-temperature heating causes material to adhere to the inner wall and coke, affecting the distillation process. Utility Model Content

The cleaning structure includes a main shaft connected to a motor and a motor output shaft, and a scraper plate at the end of the main shaft.

[0008] The isolation assembly includes an isolation cylinder and a mounting base connected to the bottom of the isolation cylinder;

[0009] The protective filtration assembly includes a filter box and a sealing cover that is inserted into the top of the filter box. A partition plate is provided in the middle of the interior of the filter box. A filter screen is provided on the partition plate near the top. The left side of the partition plate is a sedimentation chamber and the right side is a filtration chamber. The filtration chamber is provided with absorbent cotton. The right end of the filter box is provided with a guide pipe that communicates with the interior of the distillation column body. A one-way valve is provided on the guide pipe.

[0010] Furthermore, the outer diameter of the distillation column body is adapted to the inner diameter of the isolation cylinder, the bottom of the isolation cylinder and the top of the fixed base are integrally formed, and the upper surface of the fixed base near the left side is also provided with a support plate corresponding to the filter box, and the bottom of the filter box and the upper surface of the support plate are inserted into each other.

[0011] In this invention, the isolation cylinder, in conjunction with the outer side of the distillation column body, provides protection and reduces the risk of burns from direct contact by outside personnel. The support plate, in conjunction with the support plate, provides a support point for the filter box, making it easier to support the entire protective filter assembly and increasing the stability of the connection.

[0012] Specifically, the hollow area between the inner and outer walls of the isolation cylinder is a vacuum layer, and the drain pipe and exhaust pipe on the distillation column body pass through the isolation cylinder respectively.

The sedimentation compartment initially precipitates the solution entering from the inlet pipe. The filter screen intercepts large particles, reducing the amount of large particles entering the distillation column. With the help of adsorption cotton, it performs filtration and adsorption again, reducing the amount of particles entering the guide pipe and avoiding blockage of the pipe, which would affect the continuous delivery of the solution.

[0018] Furthermore, the top of the filter box is provided with an annular groove, and a sealing cover is provided in the annular groove.

[0040] In this invention, the isolation cylinder 20, in conjunction with the outer side of the distillation column body 1, provides protection and reduces the risk of burns caused by direct contact with the outside personnel. The support plate 22, in conjunction with the filter box 30, provides a support point for the filter box 30, making it easier to support the entire protective filter assembly 3 and increasing the stability of the connection.

[0041] It should be noted that the hollow area between the inner and outer walls of the isolation cylinder 20 is a vacuum layer 200, and the drain pipe and exhaust pipe on the distillation column body 1 pass through the isolation cylinder 20 respectively.

[0042] In this invention, with the cooperation of the vacuum layer 200, the interior is evacuated, and the temperature transmission is isolated in the vacuum environment, reducing the impact of the outer side of the isolation cylinder 20 on external personnel to cause burns.

[0046] It is worth noting that the partition plate 300 and the filter box 30 are integrally formed structures. The width of the outer wall of the absorbent cotton 302 is adapted to the width of the inner wall of the filter chamber on the right side of the partition plate 300. The left end of the guide pipe 32 is welded and fixed to the right end of the filter box 30, and the right end of the guide pipe 32 is welded and fixed to the distillation column body 1.

It undergoes initial sedimentation on the left side of the partition plate 300, is filtered and intercepted by the filter screen 301, and then enters the filter chamber on the right side of the partition plate 300. With the help of the adsorption cotton 302, small particles are intercepted and then enter the interior of the distillation column body 1 through the guide pipe 32. This reduces the impact of particles in the added solution clogging the pipes.
