Abstract

The invention discloses a benzene sulfonyl chloride production tail gas HCl absorption device. The HCl absorption device comprises a bottom plate, supporting rods, an outlet cover control unit, an absorption stirring unit and an outlet plug control unit, wherein four supporting columns are fixedly connected to the right side of the upper surface of the bottom plate and evenly distributed; a reaction tank is fixedly connected to the upper ends of the supporting columns; an outlet is formed in the lower end of the reaction tank; an outlet plug is installed at the outlet; an exhaust pipe is fixedly connected to an air outlet of the reaction tank; the middle of the upper end of the reaction tank is fixedly connected with a support frame; the supporting rods are fixedly connected to the left side of the upper surface of the bottom plate; the four supporting rods are evenly distributed; the upper ends of the supporting rods are fixedly connected with an absorption tank; and an air inlet pipeis installed at an air inlet of the absorption tank. The benzene sulfonyl chloride production tail gas HCl absorption device has a good effect of absorbing HCl tail gas, prevents a large amount of HCl tail gas from being discharged into air, and prevents the air from being polluted.

Description

technical field [0001] The invention relates to the technical field of fine chemicals, in particular to an HCl absorption device for tail gas produced by benzenesulfonyl chloride. Background technique [0002] The chlorosulfonation reaction of 4-[2-(acetamido)ethyl]benzenesulfonyl chloride is a very important link in the production process. The traditional process adopts positive pressure chlorosulfonation, and N-acetylphenylethylamine is slowly added into chlorosulfonate In the acid solution, hydrogen chloride (HCl) gas is continuously released during the reaction process of chlorosulfonation, and the release amount per ton of product is about 600kg. Due to the strong hydrophilic force of hydrogen chloride (HCl) gas, it adopts plane absorption, and the yield is about 68 -72%, the remaining hydrogen chloride (HCl) gas is simply absorbed by the tail gas. [0003] Existing a kind of 4-[2-(acetamido) ethyl] benzenesulfonyl chloride production tail gas HCl absorber, 4-[2-(aceta...
