Description
Technical field
The utility model belongs to the fluid purification processing technology field, especially relates to a kind of circulation type electro-adsorption liquid cleaning device.
Background technology
Known fluid purification treatment process has: chemical method, Physical (distillation method and cold method), ion exchange method, electroosmose process, reverse osmosis method, EDI method and electro-adsorption method etc.Aforesaid method cuts both ways, and such as the chemical method reduced investment, but can only remove the ion of easy generation indissoluble salt; Distillation method is high to the impurities in liquid clearance, but energy consumption is high; Ion exchange method is removed various ions in the liquid by ion exchange resin, invest lowlyer, but the resin needs regularly regenerate with strong acid, highly basic, and the salkali waste spent acid solution of discharge has caused secondary pollution; Electrodialysis and reverse osmosis all are to utilize membrane technique treatment and purification liquid, different is that electrodialysis is to utilize electrode formation electric field to order about the liquid intermediate ion to pass through ionic membrane, liquid is purified, and reverse osmosis is to order about liquid with pressure to pass through reverse osmosis membrane, hold back salinity in the liquid, both high advantages of desalination rate, but also have the problems such as power consumption height, film vulnerable to pollution, life-span weak point, electrodialysis also has the problem of battery lead plate polarization; EDI is the fluid purification technology that combines electrodialysis and the development of ion exchange technique advantage, and it has avoided the chemical regeneration of ion exchange resin, does not have secondary pollution, and very high desalination rate is arranged, but the problem that ionic membrane easily pollutes, the life-span is short is arranged equally.
Electro-adsorption is fluid purification technology of new generation, it is that low voltage and direct current is applied on the opposite polarity pair of electrodes plate, when liquid by between battery lead plate during passage, the charged particle in the liquid is subjected to electric field action, mobile being adsorbed on the battery lead plate of opposed polarity, liquid is purified.After for some time, with battery lead plate discharge or reversal connection, be adsorbed on ion desorption on the battery lead plate in scavenging solution, battery lead plate is regenerated.The electro-adsorption technology has overcome electrodialysis and reverse osmosis membrane and has easily polluted, poisons, needs periodic replacement expense height, can not process the shortcoming that contains a small amount of organic liquid without ion diaphragm; And the battery lead plate life-span is long, not fragile, and current consumption is low, has greatly saved processing cost.But the clearance that a main drawback of electro-adsorption is exactly charged particle is lower than reverse osmosis and electrodialytic technique, and the former is generally 65-85% by clearance, and latter Ke Da is more than 95%.
In sum, the fluid purification technology respectively has relative merits, reach widely applicable, reduced investment, energy consumption is low, removal of impurity is high, equipment is durable in use, also needs constantly innovate improvement to above-mentioned technology.
China Patent No. is that 01127146.9 " liquid treatment purifying module " discloses a kind of technology of removing band ionization particle in the liquid.This module comprises end plate, distribution base plate, battery lead plate, insulation bulkhead and web member, a pair of distribution base plate above and row arrangement is fixed by end plate and insulation bulkhead by web member, the distribution base plate is connected with the distribution element, the distribution base plate that is connected with battery lead plate is provided with delivery hole, and be communicated with and consist of fluid passage with liquid in-out mouth and the space between the battery lead plate on the end plate, the filler that liquid is passed through also is housed in the space between battery lead plate.It utilizes the electro-adsorption principle can effectively remove the charged particle in the liquid and is dissolved in salinity in the liquid.Can also remove colloid charged in the liquid, organism, microorganism etc.Equipment life is long, and power consumption is especially far below other fluid purification technology.But because battery lead plate adopts parallel-plate structure in the described module of this patent, the module quantity of used parts is too many, and manufacturing accuracy requires high, and manufacturing cost is high.
For addressing the above problem, China Patent No. is the technology that 200610172589.9 " rolling type electric adsorption filter elements " disclose a kind of rolling electro-adsorption device and removal charged particle.This device is to be provided with rolling electro-adsorption assembly in the housing that is provided with fluid inlet, liquid outlet and electrode, this assembly is wound on mandrel on by the composite bed that conductive layer, adsorption layer, supporting layer, adsorption layer, conductive layer, adsorption layer, supporting layer and adsorption layer (8 layers) form totally, and by the immovable bed in the outside it is tightened to be fixed on the mandrel and make.When stoste enters filter core from fluid inlet, during supporting layer in passing rolling electro-adsorption assembly, under the effect of direct current field force, the charged particle of liquid is attracted in the electrostatic double layer on adsorption layer surface and is effectively removed, and liquid is purified.This invents more last invention, has that energy consumption is low, simple in structure, the advantage of low cost of manufacture.But the described rolling electro-adsorption of this patent assembly is from axial turnover liquid, causes the clearance of liquid flow weak point, charged particle low, needs a plurality of monomer series-connected combinations; And if the tangential direction feed liquor, the liquid treatment amount is little, and liquid is rotational flow in electric adsorption filter element, and resistance is larger.What is more important, in processing module, along with liquid-flow, charged particle in the liquid is constantly adsorbed by battery lead plate, and in other words, the charged particle concentration in the liquid constantly reduces, thereby cause battery lead plate adsorption efficiency degradation, need to keep reducing the spacing of adjacent electrode plates under the substantially constant prerequisite of liquid flow rate this moment, and above-mentioned patent can't be accomplished.
Summary of the invention
