The present invention realizes above-mentioned purpose like this:
The environment-friendly disposal system of lead-acid battery pole plate production technology comprises lead dust, lead fume and lead steam collection processing system implementing and acid mist and spent acid collection processing system implementing; Wherein lead dust, lead fume and lead steam collection processing system implementing include negative pressure system, the arrival end of negative pressure system is connected to the floss hole of corresponding technological operation station, the port of export of negative pressure system connects the spraying treatment system, lead dust, lead fume and lead steam that each operation position produces are drawn into floss hole and enter into the spraying treatment system under the effect of negative pressure system, the top of spraying treatment system is provided with a large amount of shower nozzles and forms to spray in system and shroud, and the plumbous particle in the gas is sprayed adsorbed and entered the Waste Water Treatment sedimentation; The spent acid collection processing system implementing includes negative pressure system, the arrival end of negative pressure system is connected to the floss hole of corresponding technological operation station, the port of export of negative pressure system connects the spraying treatment system, the acid mist that each operation position produces is drawn into floss hole and enters into the spraying treatment system under the effect of negative pressure system, the top of spraying treatment system is provided with a large amount of shower nozzles and forms alkalescence spray and to shroud in system, acid mist is by alkalescence spraying absorption and be neutralized formation waste water, waste water enters Waste Water Treatment and regenerates, and purifying waste water that regeneration obtains is reused for the production of lead-acid battery.
Wherein, described Waste Water Treatment comprises integrated treatment pond and at least one sedimentation basin, further acid-base neutralization is carried out in the integrated treatment pond, water in the integrated treatment pond is transported to centrifugal tower through water pump, and centrifugal tower is separated the solids in the water and suspension to be discharged into then and done the trickle suspension of further precipitate and separate in the sedimentation basin and obtain to purify waste water.
Wherein, described spraying treatment system comprises tower shape main body, and the inwall of tower is equipped with a large amount of sprayers, and sprayer links to each other with high-pressure pump.
The invention has the beneficial effects as follows: native system can be divided into lead dust, lead fume and lead steam collection processing system implementing and acid mist and spent acid collection processing system implementing.Two systems adopt negative pressure system to carry out suction-type to collect, can effectively prevent pollutant in the operation position by inappropriate discharging; And two system adopt atomizing to handle, all shrouded in the whole spraying treatment system by water smoke, when land pollutant or acid pollution thing will be adsorbed sedimentation under the gravity effect then during by water smoke, all then sewage can be transported to Waste Water Treatment and regenerate, the lead powder of collecting can be put into production again on the one hand, form on the other hand and purify waste water, the production process of lead-acid battery of to be recycled of purifying waste water, therefore native system can effectively be collected and purify pollutant, reach recycling effect, reach substantially environment is realized zero-emission.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples:
Fig. 1 is the structural representation of lead dust of the present invention, lead fume and lead steam collection processing system implementing;
Fig. 2 is the structural representation of acid mist of the present invention and spent acid collection processing system implementing.
The specific embodiment
With reference to Fig. 1 and Fig. 2, the environment-friendly disposal system of lead-acid battery pole plate production technology comprises lead dust, lead fume and lead steam collection processing system implementing and acid mist and spent acid collection processing system implementing; Wherein lead dust, lead fume and lead steam collection processing system implementing include negative pressure system, the arrival end of negative pressure system is connected to the floss hole of corresponding technological operation station, the port of export of negative pressure system connects the spraying treatment system, lead dust, lead fume and lead steam that each operation position produces are drawn into floss hole and enter into the spraying treatment system under the effect of negative pressure system, the top of spraying treatment system is provided with a large amount of shower nozzles and forms to spray in system and shroud, and the plumbous particle in the gas is sprayed adsorbed and entered the Waste Water Treatment sedimentation; The spent acid collection processing system implementing includes negative pressure system, the arrival end of negative pressure system is connected to the floss hole of corresponding technological operation station, the port of export of negative pressure system connects the spraying treatment system, the acid mist that each operation position produces is drawn into floss hole and enters into the spraying treatment system under the effect of negative pressure system, the top of spraying treatment system is provided with a large amount of shower nozzles and forms alkalescence spray and to shroud in system, acid mist is by alkalescence spraying absorption and be neutralized formation waste water, waste water enters Waste Water Treatment and regenerates, and purifying waste water that regeneration obtains is reused for the production of lead-acid battery.Native system can be divided into lead dust, lead fume and lead steam collection processing system implementing and acid mist and spent acid collection processing system implementing.Two systems adopt negative pressure system to carry out suction-type to collect, can effectively prevent pollutant in the operation position by inappropriate discharging; And two system adopt atomizing to handle, all shrouded in the whole spraying treatment system by water smoke, when land pollutant or acid pollution thing will be adsorbed sedimentation under the gravity effect then during by water smoke, all then sewage can be transported to Waste Water Treatment and regenerate, the lead powder of collecting can be put into production again on the one hand, form on the other hand and purify waste water, the production process of lead-acid battery of to be recycled of purifying waste water, therefore native system can effectively be collected and purify pollutant, reach recycling effect, reach substantially environment is realized zero-emission.
