Abstract

The invention relates to an electric dialyzator which is suitable for desalting fermentation liquor. The electric dialyzator comprises an electrodialysis membrane stack unit, a plurality of sensors / transducers and a programmable logic controller (PLC) control unit; and an integrated device consists of different functional units and is suitable for performing electrodialysis on complex solutions such as the fermentation liquor so as to realize online monitoring of a plurality of parameters such as electric conductivity, pH, temperature, flow rate, pressure, current-voltage-electric consumptionand the like in the electrodialysis desalting process of the fermentation liquor, facilitate system state diagnosis and system protection and realize optimization of process condition for the electrodialysis desalting of the fermentation liquor through feedback control. The problems that the conventional electric dialyzator has high energy consumption and is difficult to run stably for a long time when used in a fermentation liquor desalting process and that effective key parameter monitoring, process control and the like are not performed are solved and engineering application of electrodialysis desalting technology of the fermentation liquor is promoted.

Description

technical field [0001] The present invention relates to the field of electrodialysis treatment process and equipment. Specifically, the present invention relates to an electrodialyzer used for fermented liquid desalination, an integrated device suitable for electrodialysis and desalted treatment of complex solutions such as fermented liquid, capable of carrying out multiple key Online monitoring and process control of parameters. Background technique [0002] Electrodialysis is a membrane separation process in which ions migrate through a selective ion exchange membrane under the action of a direct current electric field, so that charged ions are separated from aqueous solution and other uncharged components. Due to the characteristics of low energy consumption, long service life and no pollution, this technology has played an important role in various natural water desalination, seawater concentration salt production, wastewater treatment and other aspects. At present, the...
