Scraped film type sulfonator

A sulfonator and scraping membrane technology, applied in the field of scraped membrane sulfonator, can solve the problems such as the inability to quickly remove the reaction heat, the severe exotherm of the sulfonation reaction, the side reaction of oversulfonation, etc., so as to avoid oversulfonation. Even coking, the reaction temperature is mild and controllable, and the effect of less residue

Problems solved by technology

However, for organic materials with high viscosity (greater than 5000C.P), it is difficult to carry out jet atomization, and the heat release of sulfonation reaction is severe. The reaction heat of the gas jet sulfonator cannot be removed quickly, and oversulfonation is easy to occur. Chemical side reaction

Abstract

The invention relates to a wiped-film sulfonator, belonging to the manufacturing technical field for a reaction device for producing an anion active agent through sulphonation or sulphation of gas SO3. The device comprises an orthostatic reaction cylinder body (8), a stirring shaft (10) with a scraping plate (9) arranged in the orthostatic reaction cylinder body (8), a lower tube plate (11) and an upper plate(5) with a sealed tube plate (4) which are arranged at the two ends of the orthostatic reaction cylinder body; an upper head (2) with a SO3 gas inlet (1) which is arranged at the upper part of the sealed tube plate, a lower head (12) with a reactant outlet (16) arranged at the lower part of the lower tube plate (11), a motor (18) with a reducer (17) which is connected with the stirring shaft (10) and fixed at the upper head (2) or the lower head (12) and 1-3 section cooling jackets (14) with a cooling water inlet (13) and a cooling water outlet (15) which is arranged at the periphery of the orthostatic reaction cylinder body (8), etc. The general structure is designed reasonably, the operation is flexible, the manufacture is easy and the investment is small.

Description

technical field [0001] The invention relates to a scraping film type sulfonator, which belongs to the gas SO 3 The technical field of manufacturing a reaction device for producing anionic surfactants by sulfonation or sulfation. Background technique [0002] Anionic surfactants are mainly sulfonated and sulfated products. The production process is to dilute gaseous sulfur trioxide with dry air (or other inert gases) to a certain concentration, and mix with various organic substances (such as alkyl Benzene, fatty alcohol, fatty alcohol polyoxyethylene ether, α-olefin, fatty acid methyl ester and other sulfonated raw materials) contact with sulfonation or sulfation reaction to obtain sulfonation and sulfation products. Sulfonator is one of the key equipment. Existing sulfonation devices can be divided into falling film reactors (multi-tube falling film or double film falling film), jet reactors (gas jet and liquid jet, etc.) and continuous stirred tank reactors. At present,...
