Tertiary amine ammoxidation liquor settling separation device

Abstract

The utility model belongs to tertiary amine production device technical field, concretely relates to a tertiary amine amination liquid sedimentation separation device. The tertiary amine amination liquid sedimentation separation device, including pre -separating ware, sedimentation kettle, pre -separating ware is connected with the pipeline of sedimentation kettle, and pre -separating ware is provided with the pipeline of connecting with condenser, and condenser is connected with amination reaction kettle. The top of sedimentation kettle is provided with the gas inlet and nitrogen pipeline connection, and the top is also connected with the former filter jar through the liquid transfer pipe. The bottom of sedimentation kettle is provided with the discharge pipeline and the connection of the latter filter jar. The tertiary amine amination liquid sedimentation separation device provided by the utility model is through pre -separation, centrifugal sedimentation, sedimentation separation and multistage filtration, and is matched with U -shaped pipe and liquid inlet groove, avoids the interference of clear liquid main sedimentation, effectively solves the problem that the catalyst is not completely settled and the sedimentation efficiency is low in traditional technology. The liquid is taken by the inner extension pipe, and the reflux treatment improves the clear liquid recovery efficiency and guarantees the product quality.
