Head ester rectifying tower in butyl acetate production process

Abstract

The invention discloses a head ester rectifying tower in a butyl acetate production process, and relates to the technical field of rectifying tower devices. A steam outlet; a liquid inlet pipe; an intake pipe; the discharging pipe is arranged at the bottom end of the main body and penetrates into the main body; comprising an auxiliary mechanism; and a discharging mechanism. By arranging an auxiliary mechanism, the output end of a driving motor rotates to drive a rotating column to rotate, the rotating column rotates to drive a conical block to rotate, the conical block rotates and sprays water to the top end of a shaking plate, the rotating column rotates to drive a first bevel gear to rotate, and the first bevel gear rotates to drive a reciprocating lead screw to rotate; the reciprocating screw rod rotates to drive the shaking plate to reciprocate up and down, so that solids accumulated at the top end of the shaking plate can be shaken off to the bottom end of the inner wall of the main body, liquid entering the main body can be sprayed through the structure, the reaction efficiency can be improved, and the distillation efficiency of the device can be improved.

Description

technical field [0001] The invention relates to the technical field of rectification tower devices, in particular to a head ester rectification tower in the production process of butyl acetate. Background technique [0002] Butyl acetate, also known as butyl acetate, is a colorless liquid with a fruity smell. Butyl acetate is slightly soluble in water and can be miscible with general organic solvents such as alcohol and ether. Butyl is insoluble in water and difficult to be hydrolyzed, but under the action of acid or alkali, it will be hydrolyzed to produce acetic acid and butanol. Butyl acetate is the most important medium volatile solvent in the coating industry, and its volatility is high enough to be removed from It evaporates quickly during application, and is low enough to prevent shrinkage, whitening and disordered flow; it is mainly used in the paint industry, the production of fluorescent lamps, knitted fabrics, foam artificial leather, and the pharmaceutical indust...
