A multi-stage distillation tower for chemical production

By setting through grooves and fixing blocks on the fractionation plate, using connecting rods to clean residual liquid, and increasing the gas-liquid contact area by driving the fan blades to rotate, the problems of insufficient gas-liquid contact and liquid residue in multi-stage fractionation towers used in chemical production are solved, achieving more efficient fractionation and liquid cleaning.

AI Technical Summary

Technical Problem

In existing multi-stage fractionation towers used in chemical production, insufficient gas-liquid contact results in poor fractionation efficiency, and chemical liquids tend to remain on the fractionation plates and cannot be discharged.

Method used

A channel and a fixing block are set on the fractionation plate. The second connecting rod drives the first connecting rod and the fixing block to move up and down to clean up the residual liquid. At the same time, the gas pushes the fixing rod, fan blade and cover to rotate, increasing the gas-liquid contact surface and improving the fractionation effect.

Benefits of technology

It enhances the gas-liquid contact surface, improves the fractionation effect, and effectively cleans the residual liquid on the fractionation plate, ensuring the complete separation and collection of chemical liquids.

Abstract

This utility model relates to the field of chemical equipment technology, specifically a multi-stage fractionation tower for chemical production. It includes a tower body and fractionation plates disposed within the tower body. A gas pipe is located at the top of the tower body. The fractionation plates are fixedly installed on the inner wall of the tower body. Both ends of a baffle plate are in contact with the inner wall of the tower body. A baffle plate is fixedly connected to one side of each fractionation plate. A through-slot is formed at the top of each fractionation plate, and a fixed block is movably connected within the through-slot. A first connecting rod is fixedly connected to the top of the fixed block. The advantages are: by setting up a fractionation device, the gas pushes the fixed rod, fan blades, and cover to rotate on the fixed frame, thereby increasing the gas-liquid contact area and improving the fractionation effect. By setting a through-slot and a fixed block on the fractionation plate, a second connecting rod drives the first connecting rod and the fixed block to move up and down, thereby cleaning the chemical liquid remaining on the fractionation plate due to the obstruction of the baffle.
