| titleOfInvention | A kind of heavy metal absorbent of purification diluted sulfric acid and its application |
| abstract | The invention discloses a kind of heavy metal absorbent of purification diluted sulfric acid and its applications.By 50~70 parts of 30% dimethyl dithiocarbamic acid aqueous ammonium, 2~5 parts of sodium sulfite, 17%~20% 10~30 parts of ammonium sulfide solution, 5% 10~20 parts of thiourea solution and 2~5 parts of sequences of tannic acid are mixed evenly to prepare.The heavy metal absorbent is loaded in filtering adsorption tower, waste acid is introduced into adsorption tower, purified diluted acid enters plate heat exchanger via diluted acid circulating slot and cools down, introduces second motive force wave scrubbing tower after cooling and be used for flue gas washing.The product can sufficiently remove the heavy metal ion in waste acid, overcome the bad problem of conventional DTC class heavy metal absorbent treatment effect in acidic environment.It is combined with diluted acid cleansing and recycling method of the invention, under conditions of not influencing technique requirement, the acid concentration of circulation diluted acid can be obviously improved, reduced diluted acid discharge, reduce cleaning procedure water consumption, water-saving and emission-reducing significant effect. |
