Automatic defoaming multifunctional rectifying tower device and rectifying process thereof

Abstract

The invention discloses an automatic defoaming multifunctional rectifying tower device, and the device comprises a tower kettle, a metering tank, a filter, a raw material storage tank, a defoaming device, a tower body, a vacuum system, a heating system and a condensing and cooling system, wherein the lower part of the defoaming device is connected with the upper part of the tower kettle, and the upper part of the defoaming device is connected with the lower part of the tower body; the raw material storage tank, the filter and the metering tank are connected in series through pipelines and thenare connected with a feeding hole of the tower kettle, the condensation cooling system is mounted at the top of the tower body, and the top of the tower body is connected with the vacuum system through a pipeline. The method solves the problem of severe flooding caused by excessive foams in vacuum rectification, can be used for component separation of various aromatic oils or separation of multiple components in one aromatic oil, realizes continuous operation of vacuum rectification, does not need to cool the rectification tower and release vacuum after rectification is finished, and is suitable for large-scale production. The vacuum of the residual liquid tank is controlled to be lower than that of the tower kettle by the vacuum pump, and kettle residues are discharged into the residualliquid tank, so cyclic operation of procedures of feeding, rectifying, discharging and the like is realized.

Description

technical field [0001] The invention relates to the technical field of separation of aromatic oil components, in particular to an automatic anti-foaming multifunctional rectification tower device and a rectification process thereof. Background technique [0002] Aromatic oil is an important raw material for the preparation of flavors and is widely used in medicine, food, tobacco, daily chemical products and other industries. Although the amount of aromatic oil is small, it has a great impact on product quality. With the rapid development of the chemical industry, the technology of synthetic fragrances has gradually matured. This type of fragrance has greatly reduced the price of fragrances, but it also brings many negative effects, such as skin toxicity. The substances produced by the function and synthesis reaction are extremely harmful to the environment. With the improvement of national and people's awareness of environmental protection, the consumption trend of natural ...
