The utility model provides a tail gas treatment condensing filter for vacuum distillation of p-tert-butylphenol. The tail gas treatment condensing filter for the vacuum distillation of the p-tert-butylphenol comprises a condensing main body and an adsorption main body arranged at the lower end of the condensing main body, wherein a tail gas inlet for the inflow of the tert-butylphenol tail gas is formed in the condensing main body, the tail gas inlet is communicated with the outside and an inner cavity of the condensing main body, and the p-tert-butylphenol tail gas enters the condensing main body from the tail gas inlet in a negative pressure system. The condensation filter for treating the tail gas of the p-tert-butylphenol by reduced pressure distillation combines a condensation recovery method and an adsorption method, has high adsorption efficiency, solves the difficulty of distillation, condensation and recovery of solid substances, has simple equipment and small investment, can simply and efficiently recover the tert-butylphenol in the distillation tail gas, prevents the vacuum tube from being blocked by the solidification of the p-tert-butylphenol, and avoids the pollution of the discharged air and water to the p-tert-butylphenol. |
