Description

TECHNICAL FIELD

[0001] The utility model relates to chemical separation equipment technical field, concretely is a kind of rectifying column for environmental protection type chemical production. BACKGROUND

[0002] The working principle of rectifying column is based on the difference in volatility of different components, i.e., different boiling points of different components. In the column, through continuous evaporation and condensation process, low-boiling-point substances will gradually migrate to the top of the column, while high-boiling-point substances will gather at the bottom of the column. The liquid and vapor in the column will repeatedly contact on different plates or packings to achieve the distribution of substances and achieve the purpose of separation.

[0003] For example, the rectifying column for environmental protection type chemical production disclosed in CN222110971U includes a rectifying column and a support frame. The rectifying column is supported and fixed by the support frame. The lower part of the rectifying column is a stripping section, and the upper part is a rectifying section. The rectifying column is provided with a raw material pretreatment part. High molecular adsorption filter material is used to filter and treat the raw material, effectively removing solid particles, suspended solids and other impurities in the raw material, ensuring that the raw material entering the rectifying column is clean and pure. This can reduce the plugging and fouling of the tray by impurities, improve the gas-liquid contact of the raw material on the tray, and improve the mass transfer and heat transfer efficiency, thereby significantly improving the separation effect. At the same time, it also reduces the overall energy consumption of the rectifying column and reduces the discharge of waste liquid, achieving the purpose of energy saving and environmental protection.

[0004] In the above-mentioned patent, high molecular adsorption filter material is used to filter and treat the raw material, effectively removing solid particles, suspended solids and other impurities in the raw material, ensuring that the raw material entering the rectifying column is clean and pure. However, in actual use, the adsorption capacity of high molecular adsorption filter material is limited. Once a large amount of impurities is adsorbed, the material will reach saturation and cannot continue to effectively clean the impurities. The device needs to stop working and replace the high molecular adsorption filter material to continue cleaning the impurities, which affects the normal operation of the rectifying column and is inconvenient to use.

[0005] Therefore, we propose a rectifying column for environmental protection type chemical production to solve the above-mentioned problems. Utility model content
