Abstract

The invention discloses a tetrabromobisphenol A filtering and phase-splitting device, and relates to the technical field of phase-splitting devices. The tetrabromobisphenol A filtering and phase-splitting device comprises a phase-splitting mechanism and a filtering mechanism; the phase-splitting mechanism and the filtering mechanism are arranged at an interval and are communicated through a pipeline, and the phase-splitting mechanism comprises a liquid inlet header pipe, a liquid outlet header pipe, an adjusting header pipe, a liquid discharge header pipe and a plurality of phase-splitting assemblies; each phase splitting assembly is communicated with a liquid inlet header pipe, a liquid outlet header pipe, an adjusting header pipe and a liquid discharge header pipe, and the liquid outlet header pipe, the adjusting header pipe and the liquid discharge header pipe are respectively provided with a liquid outlet pump, an adjusting air pump and a liquid discharge pump; the filtering mechanism comprises a filtering assembly and an auxiliary assembly; the auxiliary assembly is positioned beside the filtering assembly, and an auxiliary pipeline for communicating the auxiliary assembly with the filtering assembly is arranged between the auxiliary assembly and the filtering assembly. Through the arrangement of the phase splitting blocks in the phase splitting assembly, the phase splitting effect of the tetrabromobisphenol A solution is effectively improved, through the arrangement of the auxiliary assembly, the filtering assembly can be cleaned in time, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of phase separation devices, in particular to a tetrabromobisphenol A filtration phase separation device. Background technique [0002] Tetrabromobisphenol A is a derivative of bisphenol A. It is a white powder and is mainly used as an additive for plastic products. It is one of the commonly used brominated flame retardants. The oxidative bromination method is one of the main methods to produce tetrabromobisphenol A. This method is carried out in a solvent in the presence of hydrogen peroxide. Add bisphenol A, n-octanol and water into the reaction flask, stir, control the temperature at 25°C, and add bromine dropwise within 45 minutes. After dropping, add hydrogen peroxide and keep warm for 10 minutes. Raise the temperature to 80°C and heat-preserve for 1 hour. Cool to crystallize, filter, wash the filter cake with ethanol and hot water successively, and dry to obtain the product. [0003] But existing f...
