Abstract

The invention discloses an esterification tower for butyl acetate production, and relates to the technical field of esterification towers. The esterification tower comprises an esterification tower body, a heating ring, at least two telescopic gas pipes, a gas supply part and a pushing assembly, the heating ring, the telescopic gas pipes and the pushing assembly are arranged in the esterification tower body, the pushing assembly and the telescopic gas pipes are fixedly connected to the inner wall of the esterification tower body, the gas supply part is installed on the outer wall of the esterification tower body, and the gas supply part is installed on the outer wall of the esterification tower body. The heating ring comprises a ring body and a gas conveying pipe, the gas conveying pipe is fixedly connected to the inner wall of the ring body, the pushing assembly is connected with the gas conveying pipe, the telescopic gas pipes are connected with the gas conveying pipe, the outer circumferential wall of the ring body abuts against the inner circumferential wall of the esterification tower body, and an inner cavity communicated with the gas conveying pipe is formed in the ring body. According to the esterification tower, n-butyl acetate on the inner circumferential wall of the esterification tower body can be completely melted conveniently, n-butyl acetate solidified on the inner wall of the esterification tower can be reduced, and the yield of n-butyl acetate is increased.

Description

technical field [0001] The invention relates to the technical field of esterification towers, in particular to an esterification tower for the production of butyl acetate. Background technique [0002] Esterification tower is a chemical equipment used for esterification reaction. Esterification is the reaction of alcohol with carboxylic acid or inorganic oxo acid to generate ester and water. Through esterification, important chemical products such as butyl acetate and ethyl acetate can be prepared. Among them, when butyl acetate is cooled, it is easy to solidify on the inner wall of the esterification tower, resulting in the problem of low product yield. Therefore, it is necessary to reduce the solidification of butyl acetate on the inner wall of the esterification tower. [0003] In the related art, an esterification tower is disclosed, which includes an esterification tower body, a conduit, a drain pipe and a water valve, the top of the esterification tower body is fixedl...
