| 摘要 |
The invention relates to the wine and alcohol-distillation industry, namely to a process for treating alcoholic distillate containing aldehyde compounds and to a device for its realization.The process, according to the invention, comprises reduction of aldehyde compounds with electrochemically generated hydrogen, upon its release on a porous electrode in the cathode space of a diaphragm electrolyzer at the current density of 0.1…0.5 A/dm3 and the linear flow rate of 0.01…0.05 m/s, and subsequent treatment of alcoholic distillate in an electrohydrodynamic cavitator with spherical magnetized ferromagnetic particles upon their magnetic liquefaction in an electromagnetic field with the magnetic induction of 0.03…0.05 T.The device, according to the invention, includes a detachable electrode unit (1), in the upper part of which is fixed an electrohydrodynamic cavitator (15). The electrode unit (1) comprises a flow-type cathode (3) and a perforated anode (9), adjacent to a membrane (4) delimiting the cathode compartment (5) from the anode compartment (8). At the same time, the electrohydrodynamic cavitator (15) comprises a housing (14) provided with a treated distillate outlet branch pipe (16 ) and a cover (21) with hydraulic lock (22), a mesh shelf (19), on which are placed spherical magnetized ferromagnetic particles (20) and an electromagnetic field generator (17) in the form of a solenoid with control unit (18). |
