Rectification equipment and rectification control method

Abstract

The invention discloses rectification equipment and a rectification control method. The rectification equipment comprises a rectification tower, an air inlet pipe, a ventilation pipe and a fixing frame, the bottom end of the rectification tower is connected with the fixing frame, an external air inlet pipe circulates in the middle of the rectification tower, the top end of the rectification towercommunicates with the ventilation pipe, the other side of the ventilation pipe communicates with a liquid storage barrel, a plurality of sets of heating pipes are installed in an inner cavity of the lower half portion of the rectifying tower through fixing clamps, the side face of the rectifying tower communicates with a circulation mechanism, a plurality of sets of first semiconductor chilling plates used for refrigeration are installed in an inner cavity of a ventilation pipe, the fixing frame comprises a movable plate, a fixing plate and supporting legs, and the matched fixing plate is welded to the periphery of the rectifying tower. The periphery of the fixed plate is sleeved with a movable plate, and the movable plate is connected with the fixed plate through a plurality of sets of countersunk bolts. According to the rectification equipment and the rectification control method, the rectification thoroughness can be guaranteed, and the rectification effect can be adjusted.

Description

technical field [0001] The invention belongs to the technical field of rectification, and in particular relates to a rectification device, and also relates to a rectification control method related to rectification. Background technique [0002] Distillation is a separation process that uses the different volatilities of the components in the mixture to separate the components. Commonly used equipment includes plate distillation towers and packed distillation towers. The principle and equipment process of precision distillation are the same as ordinary distillation, except that the relative volatility of the components in the system to be separated is small (<1.05~1.10), so high-efficiency precision packing is used to achieve the separation of the components to be separated Purify. In natural essential oils, the raw material for the production of isolated spices, isomers often coexist. For example, citronellol and rhodinol that coexist in natural essential oils such as g...
