Fig. 1 be transformation before wash acid tower schematic flow sheet；
Fig. 2 improved washes acid tower waste acidity recovery reuse means schematic flow sheet。
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described further。
Wash acid tower waste acidity recovery reuse means, including some descaling baths and some rinsing bowls, some descaling baths and some rinsing bowls by first descaling bath to end descaling bath, by first rinsing bowl to end rinsing bowl, be sequentially connected, wherein, end descaling bath is connected with first rinsing bowl；First descaling bath is connected with spent acid collection place, and end descaling bath is connected with complex acid barrel, arranges external pipeline on the individual pipeline between descaling bath and first rinsing bowl in end, and external pipeline is connected with collecting box, and collecting box is connected with washing acid tower。When descaling bath is three, and rinsing bowl is two, annexation is that the first descaling bath, the second descaling bath, the 3rd descaling bath, the first rinsing bowl and the second rinsing bowl are sequentially connected logical。
As shown in Figure 1-2, acid tower is washed before transformation, including descaling bath and rinsing bowl, descaling bath includes the first descaling bath, the second descaling bath and the 3rd descaling bath, descaling bath all adopts stepped principle of overflow, rinsing bowl includes the first rinsing bowl and the second rinsing bowl, first passes through the first rinsing bowl, the second rinsing bowl carries out water flushing。Annexation is that the first descaling bath, the second descaling bath, the 3rd descaling bath, the first rinsing bowl and the second rinsing bowl are sequentially connected, it is of course possible to be arranged as required to the number of descaling bath and rinsing bowl, herein because length restriction, a selection arranges three descaling baths and two rinsing bowls are easy to content of the present utility model is described。
The purpose that water rinses is to wash away the residual liquid of Steel Wire Surface, it is prevented that with next procedure cross-contamination。The flow process of rinsing bowl is washed for adding tap water from the second rinsing bowl, part after the second rinsing bowl first time washing can directly be discharged, part after the first rinsing bowl second time washing is directly added into descaling bath, because close to the higher value possessing recycling of pickling exit concentration。
The operation principle washing acid tower is to absorb the acid mist in descaling bath by pickling, through the dilution of therein spray form water, siphons away residue acid mist, finally makes gas reach discharge standard。
As shown in Figure 1, for transformation before wash acid tower, first descaling bath, the second descaling bath, the 3rd descaling bath, the first rinsing bowl and the second rinsing bowl are sequentially connected logical, wherein, second rinsing bowl tap water addition is 30L/h, first descaling bath is connected with washing acid tower by spent acid collection place, and washing tap water addition in acid tower is 40L/h。3rd descaling bath is connected with complex acid barrel, arranges pneumatic operated valve between the 3rd descaling bath and complex acid barrel, and complex acid barrel increases by 7 barrels of acid every day。
As shown in Figure 2, acid tower waste acidity recovery reuse means is washed for improved, first descaling bath, the second descaling bath, the 3rd descaling bath, the first rinsing bowl and the second rinsing bowl are sequentially connected logical, wherein, second rinsing bowl tap water addition is 7L/h, and the first descaling bath is connected with spent acid collection place, and the 3rd descaling bath is connected with complex acid barrel, arranging pneumatic operated valve between the 3rd descaling bath and complex acid barrel, complex acid barrel increases by 3 barrels of acid every day。Arranging external pipeline on pipeline between the 3rd descaling bath and the first rinsing bowl, external pipeline is connected with collecting box, and collecting box is connected with washing acid tower, wash acid tower is provided with the use of effusion meter and voltage stabilizing bag。The external pipeline arranged on pipeline between the 3rd descaling bath and the first rinsing bowl arranges effusion meter。
It will be apparent from the above that:
Before transformation, acid bucket is by acid: water=3:1 (namely concentration is 270g/L)；Rear acid bucket changes the pure acid of interpolation (namely concentration is about 350g/L) into。
Thus, before transformation, spent acid generation amount is: 7*680+(30+40) * 24=6440L；Before transformation, adding quantity of regenerating acid is: 7*680/4*3=3.5 ton。
After transformation, spent acid generation amount is: 3*680+(40+7) * 24=3170L；After transformation, adding quantity of regenerating acid is: 3*680=2.04 ton。
To sum up, by the recycling to spent acid, needed for both having reached to produce, decrease the use to eo-acid, simultaneously the generation amount of less spent acid by a relatively large margin。
