Description
Technical field
The utility model relates to water treatment field, particularly relates to a kind of electric absorption desalting regeneration system.
Background technology
Along with development economic and society, human demand and the requirement of quality to water is more and more higher on the one hand, and on the other hand, scope and degree that water pollutes are also increasing.
The electro-adsorption demineralization technology is as a kind of water technology, and its total technical process is divided into 2 parts, workflow, regeneration flow process.Workflow is to make the logical positive and negative electricity of electrode relative in the electro-adsorption module, utilizes the electrostatic field between the electrode to adsorb the interior zwitterion of former water, reaches the desalination purpose.The regeneration flow process is the positive and negative electrode short circuit with the electro-adsorption module electrodes, because the electric field of absorption zwitterion disappears, zwitterion meeting desorption is in module channels, and water is gone out the electro-adsorption module with desorption in the short circuit process to the whole ions in the passage, makes it to obtain regeneration.Two indexs estimating the electro-adsorption module are the desalination rate and get the water rate, the shared per-cent of salt amount that desalination rate sign product water is removed for former water module, and the salt amount of removing from former water is higher, and the desalination rate is higher.Get water rate characterization module water production rate with respect to the per-cent of total processing water yield.The product water that obtains is more for former water, and it is higher to get the water rate.The desalination rate and the water rate higher, the electro-adsorption module performance is better.
In order to satisfy the water outlet requirement, usually adopt the mode of two-stage demineralization.During work, former water enters module from electro-adsorption module bottom, by after the one-level electro-adsorption module that powers up from this module top output, be removed the product water of a part of salt by the former water as secondary electro-adsorption module, again enter from secondary electro-adsorption module bottom and power up module, the product water that meets industrial design from secondary electro-adsorption module top output saltiness, generally, because secondary electro-adsorption resume module is the product water of one-level electro-adsorption module, thereby, secondary electro-adsorption module except salt load less, the salt amount of secondary electro-adsorption module internal adsorption is also little than one-level electro-adsorption module; During regeneration, water is opposite when flow process is with work in module.Former water enters this module from secondary electro-adsorption module top, take away the salt amount that is stored in the secondary electro-adsorption module, discharge from secondary electro-adsorption module bottom, again enter one-level electro-adsorption module top, wash away and take away salt amount in the one-level electro-adsorption module, discharge from one-level electro-adsorption module bottom.This kind regeneration washes first the lower secondary electro-adsorption module of saltiness with former water, washes the higher one-level electro-adsorption module of saltiness again.
But above-mentioned electro-adsorption technical process also has its shortcoming.At first, in powering up working process, when the work that arrives during latter stage, one-level electro-adsorption module is saturated, but secondary electro-adsorption module also has suitable loading capacity because load is less, has just stopped powering up this moment and short circuit regeneration.Secondly, in the short circuit regenerative process, what secondary electro-adsorption module was used is preferably former water of water quality, the flushing water outlet of secondary electro-adsorption module and one-level electro-adsorption module is used, when one-level electro-adsorption module had been washed fully, the required washing water quantity of secondary electro-adsorption module had surpassed its actual required water yield.In sum, secondary electro-adsorption module reproduction ratio is more thorough, but adsorption efficiency is lower, and this is actually the waste of electro-adsorption module.
