Description
Technical field
The present invention relates to carbon filter, but a kind of carbon filter of electrochemical regeneration active carbon particularly.
Background technology
Active carbon has excellent suction-operated owing to having a large amount of spaces, is widely used in the fields such as the purification of water purification, material and decolouring.Active carbon can, except smelling and flavor, colourity, chlorine residue, colloid, organic matter, heavy metal and radioactive substance etc. in anhydrating, be to use the earliest water-purifying material the most widely in water purifier.
The cleaning principle of active carbon is mainly physical absorption and chemisorbed.Active carbon in use for some time, will reach absorption saturated, loses detergent power.The discarded saturated active carbon of absorption that reaches will cause the wasting of resources and secondary pollution problems.Regenerating active carbon, be with the active carbon process specially treated of the various pollutants of saturated adsorption, makes active carbon recover the adsorption capacity of the overwhelming majority, and be reused for adsorption process, thereby reduce the waste of resource.
Regeneration method of active carbon has thermal regeneration method, chemicals method of reproduction, bio-regeneration method and electrochemical regeneration method etc.Thermal regeneration method regeneration efficiency is high, be the maximum a kind of renovation process of application, but the required energy consumption of thermal regeneration is high, and in regenerative process, the active carbon loss is larger.The chemicals method of reproduction is by using chemical agent to make the pollutant desorption, and regeneration efficiency is low, and the with medicament that makes easily produces secondary pollution.The bio-regeneration method utilizes microorganism with the organic pollutant degraded of activated carbon surface absorption, and the recovery time is long, and regeneration efficiency is lower.And the electrochemical regeneration method is emerging active carbon regenerating technology, that active carbon is filled between the anodic-cathodic sheet, apply DC electric field in electrolyte, active carbon polarizes under electric field action, one section become anode, another section becomes negative electrode, form micro cell, be adsorbed on the most of oxidized decomposition of pollutant on active carbon, fraction makes regenerating active carbon because of electrophoretic action generation desorption.Regeneration efficiency is high, can reach more than 90%.
At present more about patent and the academic documents of active carbon filtering device, Electrochemical Regeneration for Activated Carbon, but can rarely have report to the active carbon filtering device that active carbon carries out electrochemical regeneration.Patent CN102772934A, CN1319108, CN201906530U, CN202569683U, CN202387266U isoreactivity carbon filter Patents all do not comprise the function that relates to regenerating active carbon.Patent CN1613552 discloses the electrochemical device of a kind of active carbon, and this device is exclusively used in the electrochemical regeneration of active carbon, does not have the purification function of carbon filter.Patent CN101891331A discloses a kind of charcoal absorption and electrochemical regeneration integrated treatment unit and using method thereof; it is characterized in that this device is provided with the adsorption column of filler particles active carbon; wherein being equipped with simultaneously to be fixed on and being equal to micropore titanium filter core electrod-array on the adsorption column flange, is to melt adsorption filtration and electrochemical treatments in the Multifunction water treatment device of one.But because this device needs to use micropore titanium filter core electrod-array, the device cost of manufacture is high.This device is when regenerating to active carbon in addition, and active carbon still is in closest packing state, causes the active carbon layer short circuit, and making most of electric energy conversion is Joule heat, thereby affects the degradation effect of pollutant, the regeneration energy consumption of increase active carbon.
Summary of the invention
But the object of the present invention is to provide a kind of carbon filter of electrochemical regeneration active carbon, the function that active carbon is regenerated that has that common carbon filter do not have, effectively extend service life of active carbon, thereby saving resource and energy consumption.
formation of the present invention: but a kind of carbon filter of electrochemical regeneration active carbon, by upper cover, the rectangle straight barrel, low head, upper intake, lower intake, the electrode group, upper waterpower distributor and lower waterpower distributor form, it is characterized in that: installing electrodes group in the rectangle straight barrel, and filling active carbon, install end socket above the rectangle straight barrel, low head is installed in below, a upper intake and lower intake respectively are set on upper cover and low head, upper intake connects waterpower distributor in upper cover, lower intake connects a lower waterpower distributor in low head.
Active carbon is filled to 1/2～2/3 height in the rectangle straight barrel; When carbon filter filters work, current are upper entering and lower leaving, when active carbon reaches absorption and carries out electrochemical regeneration after saturated, change current into bottom in and top out, active carbon suspends in water and flows through between the anode and cathode slice of electrode group under flow action,, to the anode and cathode slice energising, realize the electrochemical oxidation regeneration of active carbon this moment.
Cathode sheets and the anode strip alternative arrangement of rectangle straight tube internal electrode group, and by the pole piece fixed bar, fixed, the pole piece spacing is 10mm～200mm, decomposition voltage is 3V～30V.
Compared with the prior art, apparatus of the present invention are the function that carbon filter has increased the electrochemical regeneration active carbon; Active carbon in regenerative process, at the flow action low suspension between anodic-cathodic, can not cause between active carbon and connect short circuit, thereby maximally utilise Faradaic current, improve regeneration efficiency.Install in addition the electrode that uses and be the chip electrode, make, install simply, cost is low.
