Problems solved by technology
This kind of equipment consumes a lot of energy and has low utilization rate of heat energy.
[0004] At present, my country's existing traditional Chinese medicine production alcohol distillation process has problems such as high energy consumption, low heat energy utilization rate, large waste water discharge, and low equipment automation. In order to reduce energy consumption in the alcohol distillation process, improve heat energy utilization rate, and reduce waste water discharge, It is necessary to develop a medicinal alcohol rectification device to realize energy saving and emission reduction in the alcohol recovery process

Embodiment Construction
[0025] The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly. The implementation conditions used in the examples can be further adjusted according to specific requirements, and the unspecified implementation conditions are usually the conditions in routine experiments. In addition, unless otherwise specified, there are no specific requirements and restrictions for detecting temperature and humidity.
[0026] This embodiment provides a medicinal alcohol rectification device, which aims to use the characteristics of the different boiling points of alcohol and water, and by controlling the temperature at the top of the tower, the alcohol is distilled out of the tower body, and the water is left in the tower for separation, so as to achieve the goal of recovering...

Abstract
The invention discloses a medicinal alcohol distillation apparatus, which includes a material feeding pump, a secondary preheater, a rectification column, a reboiler, an overhead condenser, a buffer tank, and a column top preheater and a balancing tank. The material feeding pump is connected to the column top preheater which is then connected to the secondary preheater. The secondary preheater isconnected to the rectification column which is then connected to the reboiler. The top of the rectification column is connected to the column top preheater so that alcohol vapor enters the column toppreheater for transmitting heat to diluted alcohol. The column top preheater is also connected to the balancing tank so that liquefied alcohol in the column top preheater flows into the balancing tank. The column top preheater is connected to the overhead condenser so that non-liquefied alcohol vapor enters the overhead condenser and is liquefied. The balancing tank is connected to the overhead condenser so that the alcohol liquefied by the overhead condenser flows into the balancing tank. The balancing tank is connected to the buffer tank so that the mixed alcohol in the balancing tank flowsinto the buffer tank for storage. The medicinal alcohol distillation apparatus is improved in heat energy utilization rate and reduces energy consumption of recovery of the medicinal alcohol.
Description
technical field [0001] The invention relates to the field of traditional Chinese medicine pharmacy, in particular to a medicinal alcohol rectification device. Background technique [0002] With the rapid development of traditional Chinese medicine in my country, alcohol is used as the main extraction solvent and purification solvent, and the consumption is increasing day by day. Therefore, reclaiming the discarded dilute alcohol and ensuring the quality of the recovered alcohol to make it meet the reuse standard for reuse are the main ways for the majority of traditional Chinese medicine pharmaceutical companies to reduce production costs and improve economic benefits. The working principle of alcohol distillation is to use the azeotropic point of alcohol-water (95.6: 4.4, v / v) and the boiling point of alcohol to be lower than the boiling point of water. At this time, the water has not reached the boiling point, and basically does not volatilize, so that the high-concentrat...
