Description

Technical Field

[0001] The utility model relates to the technical field of pesticide intermediate production, in particular to a novel distillation tower for pesticide intermediate production. Background Art

[0002] A distillation tower is a tower-type vapor-liquid contact device for distillation. It utilizes the different volatilities of the components in the mixture, that is, the different vapor pressures of the components at the same temperature, to transfer the light components (low boiling substances) in the liquid phase to the gas phase, and the heavy components (high boiling substances) in the gas phase to the liquid phase, thereby achieving the purpose of separation. In the production process of pesticide intermediates, distillation towers are usually used to distill materials.

[0003] The existing patent document with technical announcement number CN212090966U provides a new distillation tower for the production of pesticide intermediates. The existing distillation tower cannot control the temperature well. Since different substances require different temperatures, temperature control is a very important step, and a condensing device needs to be connected separately, which makes the operation complicated. The utility model has a reasonable structure and is easy to operate. The baffle can be moved by an electric telescopic rod, so that the size of the through hole can be controlled, which is convenient for controlling the flow of hot gas entering the distillation bin, so that the temperature can be controlled. The steam can be quickly condensed into liquid through the condenser for easy collection.

[0004] However, when the new distillation tower for the existing pesticide intermediate production is used, it is not convenient to automatically clean the materials attached to the inner wall of the distillation tower. When the materials adhere to the inner wall of the distillation tower during the distillation process and cannot be cleaned, it will affect the distillation effect of the distillation tower on the pesticide intermediate materials, and the residual materials inside the distillation tower will affect the extraction purity of the second distillation operation, which is not convenient to meet people's usage needs.
