Problems solved by technology

Membrane reactors are divided into three types: single-membrane, double-membrane and double-tube, among which the double-membrane sulfonator is the most widely used membrane sulfonator at present. The whole reactor is divided into three parts: the top is the distribution part , used to distribute the material to form a liquid film; the middle is the reaction part, and the material completes the reaction in the annular space; the bottom is the tail gas separation part, where the reaction product sulfonic acid and tail gas are separated. In the sulfonation reactor of this structure, the reaction product sulfonic acid, The reaction is not thorough enough to guarantee product quality

Abstract

The present invention discloses a sulfonation reactor and a use method thereof, and belongs to the field of sulfonation reaction equipment. The sulfonation reactor comprises a sealed reaction container, wherein the top of the reaction container is provided with a plurality of material inlet pipes, the bottom of the reaction container is provided with a material outlet, the top of the reaction container is vertically provided with an emptying pipe, and is further vertically provided with a co-current pipe, the top of the co-current pipe is sealed and is provided with a ventilation pipe, the side wall of the co-current pipe is provided with a material inlet, a circulation pipeline is connected and arranged between the material inlet and the material outlet, one circulation pipeline end close to the material outlet is provided with a material discharge valve, the circulation pipeline is further provided with a material feeding pipe, and the material feeding pipe is provided with a material feeding valve. According to the sulfonation reactor with the structure, during use, a material is subjected to a circulation reaction in the reactor through the circulation pipeline so as to increase a sulfonic acid concentration and improve product quality, and the sulfonation reactor is provided with a thermometer casing and a temperature control device so as to ensure a reaction rate and reaction quality of the sulfonation reaction.

Description

technical field [0001] The invention relates to the field of sulfonation reaction equipment, in particular to a sulfonation reactor, and also relates to a method for using the sulfonation reactor. Background technique [0002] There are two types of sulfonation reactors: tank type and membrane type. Membrane reactors are divided into three types: single-membrane, double-membrane and double-tube, among which the double-membrane sulfonator is the most widely used membrane sulfonator at present. The whole reactor is divided into three parts: the top is the distribution part , used to distribute the material to form a liquid film; the middle is the reaction part, and the material completes the reaction in the annular space; the bottom is the tail gas separation part, where the reaction product sulfonic acid and tail gas are separated. In the sulfonation reactor of this structure, the reaction product sulfonic acid, The reaction is not thorough enough to guarantee product qualit...
