Description

Technical Field

[0001] The utility model relates to the field related to butadiene extraction, in particular to a butadiene extraction device. Background Art

[0002] Butadiene is an organic compound with the chemical formula C4H6. It is a colorless gas with a slight aromatic odor. It is insoluble in water but soluble in most organic solvents such as acetone, benzene, acetic acid, and esters. It is a raw material for the manufacture of synthetic rubber, synthetic resin, and nylon. Butadiene is extracted and separated by multiple extraction and distillation of C4 hydrocarbons using the DMF extractive distillation method.

[0003] A butadiene extraction device proposed in the prior art utility model patent publication number CN221385254U utilizes a stirring element and a transmission component to accelerate the mixing speed of the butadiene raw material and the extractant within the device and the distillation heating speed, thereby effectively increasing the extraction speed of butadiene. Furthermore, the device uses air cooling to dissipate heat from the water in the distillation condensation area, thereby improving water resource utilization.

[0004] However, the structure of its stirring element is relatively complex, and is achieved through the cooperation of multiple sets of gears and rotating rod structures. It takes up a large space and has high manufacturing and subsequent maintenance costs. It is also more prone to problems such as jamming and damage during use, which reduces the practicality of the device. At the same time, it does not have the ability to discharge waste gas, and directly introduces waste gas and water vapor into the circulation at the same time, which easily leads to harmful components in the water vapor and cannot be effectively recycled. Therefore, we need to upgrade and transform the existing technology to overcome the existing problems and shortcomings. Utility Model Content
