Description

Technical Field

[0001] The utility model belongs to the technical field of distillation devices, in particular to a distillation device for dicumyl peroxide. Background Art

[0002] Dicumyl peroxide, an important organic peroxide, is widely used in the production of chemical products such as rubber, plastics, and coatings as a crosslinking agent, initiator, or catalyst. However, distillation and purification are crucial steps in its production, directly impacting product quality and production efficiency.

[0003] Traditional dicumyl peroxide distillation units have exposed several problems in practical applications. First, the uneven distribution of material and steam within the distillation column results in excessively high material concentrations in some areas and low concentrations in others. This not only affects the efficiency of distillation purification but can also lead to unstable product quality. Second, because the raw materials enter the distillation column without preheating, a large amount of steam is consumed for heating, resulting in high energy consumption for the entire distillation process. Furthermore, traditional condensers also have shortcomings in condensation efficiency, and some purified dicumyl peroxide fails to fully condense, resulting in product loss and environmental pollution.

[0004] To address these issues, existing researchers have been exploring new distillation equipment and technologies. However, existing improvements mostly focus on optimizing the internal structure of the distillation column, such as adding packing layers and changing the tray type. While these improvements have improved distillation efficiency to a certain extent, they haven't fundamentally addressed issues such as uneven material and vapor distribution, high energy consumption, and poor condensation.

[0005] Therefore, there is an urgent need for a new type of dicumyl peroxide distillation device that can overcome the shortcomings of the existing technology, achieve uniform distribution of materials and steam, reduce energy consumption, and improve condensation effect, thereby ensuring the quality and production efficiency of dicumyl peroxide products.
