Description

Technical Field

[0002] Butyl octanol is an organic compound synthesized from butanol and octanol, has a special smell, can form azeotropes with water and various compounds, and has moderate toxicity; most of the existing butyl octanol tail gas condensation recovery devices pass the butyl octanol tail gas into the condensation recovery device, and use a condensation component (such as a condensation tank into which condensate is passed) to condense and recover the butyl octanol tail gas; however, the existing butyl octanol tail gas condensation recovery devices still generally have the problem that the butyl octanol tail gas and the condensation component have a short contact time and a limited contact area, resulting in poor condensation effect.

[0003] After searching, a condensation and recovery device for 1-decyl alcohol tail gas with announcement number CN218280614U is found, which includes a condensation tank, a tail gas inlet pipe, a condensate outlet pipe, several spirally coiled tubes, several air inlet branch pipes, several condensate branch pipes and a cooling fin group.
