Self-cleaning iron ion removing separation device

Technical field

The utility model relates to a kind of separating device, specifically a kind of self-cleaning iron ion removing separation device.

Background technology

According to non-faraday's phenomenon, numerous B metals (contain the slag after the non-ferrous metal metallurgy of a large amount of positive charges, certainly must pass through screening) can exchange with the negative ions in the waste water, change ionic structure and become molecule, adopt corresponding isolation technique, the iron ion of removing in the waste water is one of method wherein.This technology at home and abroad water treatment field be used widely, effect is also very good.According to adopting at present both at home and abroad the B metal to exchange the equipment of iron ions, generally adopt mechanical filter and sand-bed filter, more than two kinds of equipment because processing cost is low, use often in the water treatment field at home and abroad.

Non-faraday's electrolysis tech is removed ion in wastewater treatment industry and is approved extensively that problem is after the electrolysis, the B metal lumps easily, and after the after chemical reaction, dirt is wrapped in above the B metal, ion can not be contacted with the B metal, therefore stopped chemical reaction.When just using, effect is fairly obvious simultaneously, and along with successive reaction, effect constantly decays.Therefore must stop to produce, adopt a large amount of anti-cleanings of cleaning water, and the anti-waste water that washes down must carry out re-treatment again, thereby increase running cost; Be not easy the pine bed in addition after the B metal caking, often need the B metal in the machine taken out and clean, increased cost of labor again, can not continuous production when cleaning simultaneously, delay the amount of wastewater treatment.

Summary of the invention

The purpose of this utility model is a kind of self-cleaning iron ion removing separation device of design, adopts the ultimate principle of fluidized-bed, in conjunction with the innovative technology that cleans and return automatically the B metallic substance automatically; when separating; do not need to shut down and clean, do not need to waste rinse water, solved loose bed problem simultaneously.

According to the technical scheme that the utility model provides, be the filter bed of placing the compound of manganese sand and B metal in the bottom of staving, the water distribution cover is arranged in filter bed, water-supply pipe is set on the top of staving, described water-supply pipe is connected with described water distribution cover; The water outlet sand tube is arranged in staving, and the lower end of described water outlet sand tube is positioned at the bottom of staving, and the upper end of described water outlet sand tube is connected with the auger that is positioned at staving top; The position that faces the water outlet sand tube in the bottom of staving is provided with compressed air outlet, clear water output is being set above corresponding to filter bed on the wall of staving;
