Description
Technical field
this utility model relates tothe water reuse of phosphoric acid production
field.
Background technology
In phosphoric acid production line, use sulfuric acid decomposition phosphorus ore, generate phosphoric acid and phosphogypsum, be separated by filtration out phosphoric acid, by-product phosphogypsum water is transported to phosphogypsum storehouse by Pulp pump after sizing mixing, phosphogypsum deposits in storehouse, phosphogypsum post-depositional waste water in phosphogypsum storehouse remains a large amount of phosphate radical and sulfate ion, pH value is 1---between 2, normally get back to phosphoric acid production system, to size mixing water as filtration and washing water and phosphogypsum, along with time lapse, in water body, contained acid ion concentration can constantly increase, cause pipeline scale serious, affect phosphoric acid normally produce and cause Washing ratio index to decline.And phosphate reverse flotation system water is sour water, usually adopt sulfuric acid or phosphoric acid to carry out pH value adjustment, reach after reverse flotation produces pH value (about 5.0) and could use.Show thus: the waste water on the one hand in phosphoric acid production line contains phosphate radical and sulfate ion, direct circulation is used for, in phosphoric acid production line, affecting phosphoric acid and normally producing; The sour water of phosphate reverse flotation system will use sulfuric acid or phosphoric acid to carry out pH value adjustment on the other hand.
Summary of the invention
The purpose of this utility model is exactly at present, and the waste water in phosphoric acid production line contains phosphate radical and sulfate ion, and direct circulation is used for, in phosphoric acid production line, affecting phosphoric acid and normally producing; And the sour water of phosphate reverse flotation system will use sulfuric acid or phosphoric acid to carry out pH value adjustment, consume the deficiency of sulfuric acid or phosphate raw material, and the reverse flotation system of the waste water process for processing phosphorus ore utilizing phosphoric acid production line is provided.
The utility model is made up of the phosphogypsum storehouse waste water pond for recovering of ball mill, swirler, agitation vat, flotation cell, thickener, concentrate back pool, phosphoric acid production line; The water outlet of the phosphogypsum storehouse waste water pond for recovering of phosphoric acid production line communicates with concentrate back pool, one road water outlet of concentrate back pool communicates with the ore discharge port of ball mill, another road water outlet communicates with flotation cell, the ore discharge port of ball mill communicates with the opening for feed of swirler, the coarse fodder outlet of swirler communicates with the opening for feed of ball mill, the fines outlet of swirler communicates with agitation vat, agitation vat opening for feed communicates with flotation cell, the concentrate outlet of flotation cell communicates with the opening for feed of thickener, and the water outlet of thickener communicates with concentrate back pool.
The utility model has the advantages that: be incorporated in concentrate through reverse flotation back pool by the acid waste water (PH=1.0-2.0) that phosphoric acid production is produced, regulate concentrate backwater pH value, turn back to reverse flotation system, reduce sulfuric acid dosage in reverse flotation production process; Containing a large amount of phosphate anions in sour water, the effect (suppressing phosphorus ore to float) of inhibitor can be played in reverse flotation production process, save phosphoric acid consumption, reduce mine tailing, improve phosphorous recovery.Use phosphoric acid production filter punch plate washing water instead clear water simultaneously, improve Washing ratio index, form water of productive use benign cycle.

Embodiment
The utility model stirs bubble Droplets groove 2 by ball mill 1, direct flotation, reverse flotation stirs bubble Droplets groove 3, positive Tailings Dam 4, anti-Tailings Dam 5, the high-order wastewater disposal basin 6 of homocercal fin, the high-order wastewater disposal basin 7 of anti-tail, thickener 5, concentrate wastewater disposal basin 6, A mortar pump 7, B mortar pump 11 are formed, and the discharge port of ball mill 1 is made up of the phosphogypsum storehouse waste water pond for recovering 7 of ball mill 1, swirler 2, agitation vat 3, flotation cell 4, thickener 5, concentrate back pool 6, phosphoric acid production line with the utility model that top-ups; The water outlet of the phosphogypsum storehouse waste water pond for recovering 7 of phosphoric acid production line communicates with concentrate back pool 6, one road water outlet of concentrate back pool 6 communicates with the ore discharge port of ball mill 1, another road water outlet communicates with flotation cell 4, the ore discharge port of ball mill 1 communicates with the opening for feed of swirler 2, the coarse fodder outlet of swirler 2 communicates with the opening for feed of ball mill 1, the fines outlet of swirler 2 communicates with agitation vat 3, agitation vat 3 opening for feed communicates with flotation cell 4, the concentrate outlet of flotation cell 4 communicates with the opening for feed of thickener 5, and the water outlet of thickener 5 communicates with concentrate back pool 6.
Mode of operation: concentrate back pool is sent in phosphogypsum storehouse acid waste water (PH=1.0-2.0) of phosphoric acid production line, ((PH=5) mixes with the backwater coming from thickener in concentrate back pool, the water PH=3-3.5 of mixing, then the ore discharge port that ball mill is sent on Shui mono-tunnel is mixed, use as ore discharge water, flotation cell is sent on another road of water of mixing, uses as Pao Droplets wash-down water.The abrasive material of ball mill sends into swirler together with ore discharge water, and the coarse fodder after separation enters ball mill and regrinds, and the fines after separation sends into flotation cell after agitation vat stirs.Concentrate after flotation enters thickener.
By full sour water workflow reengineering---phosphoric acid slag reservoir backwater (sour water PH=1.0-2.0) is delivered continuously to the floating system of enrichment plant mill by transferpump, reduce concentrate backwater pH value (PH controls at 3.0-3.5), reduce reverse flotation sulfuric acid (adjustment pH value) consumption 50Kg/t and phosphoric acid (inhibitor) consumption 20Kg/t, mine tailing declines 25%, reduces beneficiation cost about 35 yuan/t.
Phosphoric acid production filter filter disc wash-down water uses clear water instead, and the Washing ratio index of phosphoric acid production brings up to more than 99.3% from 99.0%.
