METHOD OF REGENERATION OF THE ACTIVE CHARCOAL AND THE SYSTEM FOR ITS REALIZATION Russian patent published in 2007 - IPC B01J20/34 C01B31/08 

FIELD: alcoholic beverage industry; food industry; other industries; methods and devices for regeneration of the active charcoal.

SUBSTANCE: the invention is pertaining to the process engineering exploiting the adsorption properties of the active charcoals and may be used for regeneration of the active charcoals after the definite operational cycles at purification of the alcoholic beverage products, the potable water and the waste waters. The active charcoal is heated up to (1-1.2) T_cr and treated with the extractant at the pressure of (1-5) Р_{cr ,} where_{Тcr andРcr - the critical temperature and pressure of the used extractant respectively. At that the direction of the extractant flow is set descending at Re≤20 and - ascending - at Re>20. Regeneration is carried out in the system containing the throttling device, the separator, the compressor or the pump, the withdrawal valve, the adsorber-extractor, which upper end is connected to the inlet of the throttling device, which outlet is connected to the inlet of the separator. The upper outlet of the separator is connected to the inlet of the compressor or the pump. The lower outlet of the compressor is connected to the withdrawal valve. The outlet of the compressor or the pump is connected to the lower end of the adsorber-extractor. In addition between the adsorber-extractor and the throttling device and between the compressor or the pump and the adsorber-extractor there are the installed valves. At that the upper end of the adsorber-extractor through the valve is connected to the outlet of the compressor or the pump and the lower end of the adsorber-extractor through the valve is connected to the inlet of the throttling device. The technical result of the invention is the reduced time of the regeneration of the active charcoal with simultaneous reduction of the power input, the possibility of regeneration of the finely dispersed charcoal and its multiuse.}

EFFECT: the invention ensures the reduced time of the regeneration of the active charcoal with simultaneous reduction of the power input, the possibility of regeneration of the finely dispersed charcoal and its multiuse.
