Abstract

The invention discloses a countercurrent operated plate frame type electric regenerating device for inactive ion exchange resin. The device comprises a membrane stack, electrode devices and a clamping device. The membrane stack consists of a plurality of groups of membrane pairs; each group of membrane pairs comprises a cation-exchange membrane, a resin regeneration chamber partition board, an anion-exchange membrane and a thick water chamber partition board; and two sides of the membrane stack are provided with the electrode devices, and the membrane stack and the electrode devices are compacted by using the clamping device on the exterior so as to assemble the plate frame type electric regenerating device for the ion exchange resin. Water flows of a resin regeneration chamber and a thick water chamber in the device can run stably for long term in a countercurrent operation mode, so the resin regeneration effect is good; and meanwhile, the device does not consume acid or alkali chemical agents during running, does not discharge waste liquid and waste water, and only consumes a little electric energy, so the device has the advantages of low energy consumption, simple operation andconvenient use and can be widely applied to inactive regeneration of various mixed-bed resin, polished resin, softened resin and positive and negative resin.

Description

technical field [0001] The invention relates to the regeneration field of ion exchange resins, in particular to an electric regeneration device for exhausted ion exchange resins in countercurrent operation of ultrapure water production. Background technique [0002] Ultrapure water is used as high-quality production process water, supporting water for production equipment (high-pressure boilers) and water for analysis and experiments. Technology companies, various testing centers and other social development fields. Ultrapure water is widely used in analytical laboratories, biochemical industry, microelectronics industry, semiconductor industry, power generation industry, pharmaceutical industry and hospitals. In vitro electrical regeneration of ion exchange resins is a green process change for existing ion exchange water treatment, which is very suitable for the renovation of many old factories and the recycling of traditional disposable polishing resins. [0003] At pres...
