Reaction vessel negative pressure distilled water separating apparatus

Abstract

The invention discloses a reaction vessel negative pressure distilled water separating apparatus which comprises a reaction vessel body. A separating apparatus is arranged in the reaction vessel body and comprises a distillation column, a condenser, a separator, a reception tank and a vacuum pump, wherein the reaction vessel body is communicated with the distillation column through a pipeline, the distillation column is communicated with an inlet of the condenser through a pipeline, an outlet of the condenser is communicated with the separator through a discharging pipe, one side of the separator is provided with a reflux inlet, the reflux inlet is communicated with the reaction vessel body through a reflux pipe, the bottom of the separator is provided with a water rising opening, the water rising opening is communicated with the reception tank through a water rising pipe, and the tops of the separator and the reception tank are respectively connected with the vacuum pump through pipelines. The apparatus provided by the invention overcomes the following problems in usage of a traditional reaction vessel separator: water is taken back to a reaction vessel with a solvent during two-phase separation by the traditional separator under the condition of a negative pressure, and a separation effect of a solvent and water is poor, which causes reduction in product yield, delay of reaction time, reduction in production efficiency and the like.

Description

[0001] technical field [0002] The invention relates to the technical field of reactor equipment, in particular to a reactor negative pressure distilled water separation device. Background technique [0003] In the process of the negative pressure distillation reaction system, the two-phase liquid is separated, the solvent phase is reused, and the water phase is completely separated to ensure continuous production. It can be seen that solvent separation is an important step in resource reuse. At present, enterprises usually use traditional separators for two-phase separation. Under the negative pressure conditions of traditional separators, there is a phenomenon that water is brought back to the reaction kettle with the solvent, and the separation effect of solvent and water is not good, resulting in reduced product Yield, cause the delay of reaction time, reduce production efficiency.
