AI Technical Summary

Technical Problem

The existing dichloroethylene distillation tower has a short contact time between the gas phase and the liquid phase, and insufficient mixing, resulting in low efficiency in the transfer of light and heavy components. Repeated cycle distillation is required, which is costly and inefficient.

Method used

The design of the first honeycomb plate, the second honeycomb plate, the third honeycomb plate, the first guide plate, the second guide plate and the third guide plate is adopted to make the gas phase and the liquid fully contact in the tower body. At the same time, the transmission motor, the rotating rod, the blanking blade and other components are used to extend the contact time and clean the dirt on the bottom wall of the tower body.

Benefits of technology

The transfer efficiency and effect of light and heavy components are improved, the number of repeated distillation cycles is reduced, the cost is reduced and the work efficiency is improved.

Abstract

The utility model discloses a dichloroethylene rectifying tower which comprises a tower body, one side of the tower body is fixedly connected with a liquid inlet pipe, the lower end of the tower body is fixedly connected with a liquid discharge pipe, one side of the liquid inlet pipe is fixedly connected with a connecting pipe, and one side of the connecting pipe is fixedly connected with a shunting ring pipe. A plurality of nozzles are fixedly connected to the lower end of the shunting ring pipe, a first honeycomb plate, a second honeycomb plate and a third honeycomb plate are arranged in the tower body, and a first guide plate, a second guide plate and a third guide plate are arranged in the tower body; by arranging the first honeycomb plate, the second honeycomb plate, the third honeycomb plate, the first guide plate, the second guide plate and the third guide plate, a gas phase rises through the lower part of the tower body, a liquid passes through the first honeycomb plate, the second honeycomb plate and the third honeycomb plate, and under the guide action of the first guide plate, the second guide plate and the third guide plate, the contact time of the gas phase and the liquid is long; therefore, the liquid and the gas phase can be more fully mixed.
