RECTIFICATION PLANT DEVICE Russian patent published in 2020 - IPC B01D3/00 C12G3/00 C12P7/06 

FIELD: chemistry.

SUBSTANCE: invention relates to equipment for rectification of alcohol. Invention relates to a rectifier apparatus comprising a sequentially connected interconnected distillation cube provided with a heater, reflux tank with a steam lift reflux for feed of a rectification column, a rectification column and a dephlegmator. Reflux tank includes housing equipped with branch pipe of connection with rectification column and connection pipe with distillation cube, reinforcing column of reflux tank in form of cylinder with contact heat and mass exchange means, installed inside housing and communicating with branch pipe of connection with distillation cube, cylindrical nozzle with holes along the perimeter of its lower part, enclosing the reinforcing column of the reflux tank, installed coaxially with it with a gap δ, located in range from 0.03 to 0.07 of reflux tank reinforcing column pipe wall radius, wherein the height of the cylindrical nozzle is greater than the height of the reinforcing column of the reflux tank. Reflux baffle is arranged above cylindrical nozzle opposite branch pipe of connection with rectification column. Housing is equipped with a nozzle with a tap for draining reflux residues, which are arranged in the lower part of the housing, and a nozzle in the upper part of the housing for installation of a thermometer.

EFFECT: high degree of purification of alcohol from impurities, considerable reduction of sampling time and maximum possible yield of the commercial product.
