Problems solved by technology
The current dealcoholization technology generally adopts the method of heating the material in a vacuum state, stirring, and separating and removing methanol by vaporization. The disadvantage of this technology is: due to the presence of glycerol (glycerol) and dissolved soap in the crude ester, the production of methanol The encapsulation effect makes part of the methanol unable to be vaporized and removed, which affects the dealcoholization effect, and is not conducive to the sedimentation of glycerin and dissolved soap, which brings a great burden to the subsequent distillation process, affects the output, and restricts the production scale.

Abstract
The invention discloses a biodiesel methyl esterification dealcoholysis device, which comprises a transfer pump (1), a charging inverted valve (2), a flash evaporation tower (3) with multilevel tower inner distribution plates (32) and tower inner trays (33), a vision cup (4), a discharging inverted valve (5), a methanol condenser (6) and a vacuum device, wherein an outlet of the transfer pump is connected with the charging inverted valve (2) by a pipeline and then connected with an inlet of the flash evaporation tower; an outlet for low-boiling-point substances on the top of the flash evaporation tower is successively connected with the vision cup (4) and the methanol condenser (6) by pipelines; and a discharge hatch at the bottom of the flash evaporation tower is connected with the discharging inverted valve (5) by a pipeline. The biodiesel methyl esterification dealcoholysis device can be used to effectively remove methanol before aliphatic acid methyl ester enters a next process without influencing the settlement of glycerin and dissolved soap, and has a rapid and high efficient dealcoholysis characteristic.
Description
1. Technical field [0001] The invention relates to organic chemical product production equipment, in particular to a dealcoholization device in biodiesel methyl esterification production equipment. 2. Background technology [0002] In the production process of biodiesel (fatty acid methyl ester) using waste animal and vegetable oil, a kind of low boiling point industrial raw material methanol with a boiling point of 63.5°C must be used; in the methyl esterification synthesis reaction process, in order to improve the conversion rate of biodiesel products Methanol is recycled in excess; after the methyl esterification synthesis reaction is completed, there is a large amount of methanol in the crude fatty acid methyl ester, which must be removed for subsequent distillation production. The current dealcoholization technology generally adopts the method of heating the material in a vacuum state, stirring, and separating and removing methanol by vaporization. The disadvantage of t...
