Description
Technical field
The invention belongs to chemical technology field, is related to a kind of sulfuric acid waste reclaiming clean device.
Background technology
The widely used wet cleaning cleaning dust falling temperature technique processing flue gas during smelting of sulfuric acid acid making system, in processing procedure
In, the constantly enrichment such as washing liquid acidity, sour temperature, dust-laden, harmful substance is, it is necessary to open a way, so as to generate a large amount of acid waste waters, together
When require supplementation with a large amount of new water, arranged outside acid waste water, environmental pollution can be caused, need to be administered；At present, lime neutralisation is ratio
More ripe process for treating acidic sewage, but it is big to invest height, waste residue amount；There is also operating cost height etc. to ask for other administering methods
Topic.
The content of the invention
The purpose of the present invention is that a kind of sulfuric acid waste reclaiming clean device is provided the problem of presence for prior art.
The concrete technical scheme of the present invention is as follows：
A kind of sulfuric acid waste reclaiming clean device, including purifying column, degassing tower, sour water storage tank, filter press, concentration tower, acid mixing device
Tower is inhaled with tail, the purifying column discharging opening is connected by slush pump with degassing tower charging aperture, degassing tower discharging opening and sour water storage tank

Material mouth is connected, and concentration tower discharging opening is connected with acid mixing device；Exhaust outlet, the degassing tower exhaust outlet of purifying column are connected to purification negative pressure cigarette
Road, the exhaust outlet of concentration tower are connected to tail and inhale tower；
The reverse jet tube of the concentration tower is connected with two suction tower exhaust pass.
The invention has the advantages that：
The present invention can carry out effective purified treatment to sulfuric acid waste, can effectively reclaim sulfuric acid in sulfuric acid waste into
Point, finished product sulfuric acid concentration is inhaled for adjusting to do, caused waste residue amount is extremely low after purified treatment, and can effectively reclaim wherein
Valuable metal.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
A kind of sulfuric acid waste reclaiming clean device as shown in Figure 1, including purifying column 1, degassing tower 2, sour water storage tank 3, press filtration
Machine 4, concentration tower 5, acid mixing device 6 and tail inhale tower 7, and the discharging opening of purifying column 1 is connected by slush pump 8 with the charging aperture of degassing tower 2,
The discharging opening of degassing tower 2 is connected with the charging aperture of sour water storage tank 3, and the discharging opening of sour water storage tank 3 passes through filter pressing pump 9 and the charging aperture of filter press 4
Connection, the discharging opening of filter press 4 are connected with the charging aperture of concentration tower 5, and the discharging opening of concentration tower 5 is connected with acid mixing device 6；The row of purifying column 1
Gas port, the exhaust outlet of degassing tower 2 are connected to purification negative pressure flue 10, and the exhaust outlet of concentration tower 5 is connected to tail and inhales tower 7, the concentration
The reverse jet tube of tower 5 is connected with two suction tower exhaust pass 11.
Specific work process of the present invention is as follows：
Sulfuric acid waste enters purifying column 1, is well mixed the mud in waste liquid and liquid by the vortex separating tube of purifying column 1, purification
Caused sulfur dioxide gas is discharged into recycling in purification negative pressure flue in tower 1, and the waste liquid being well mixed in purifying column 1 leads to
Cross slush pump 8 and deliver into degassing tower 2 and be de-gassed operation, the sulfur dioxide gas in waste liquid is discharged into purification negative pressure flue
Middle recycling, the waste liquid after degassing process, which enters in sour water storage tank 3, to be stored, and the waste liquid in sour water storage tank 3 passes through pressure
Filter pump 9 delivers into filter press 4, and filter press 4 carries out separation of solid and liquid, and obtained solid waste can carry out valuable metal recovery, obtain
To sour water clear liquid be delivered in concentration tower 5 and carry out concentration, meanwhile, two inhale the tower 11 inverse sprays to concentration tower 5 of exhaust pass
Conveying dry flue gas, takes away part water, fluorine, chlorine in sour water clear liquid in pipe, and inhaling tower 7 into tail is absorbed, at the concentration of concentration tower 5
Dilute sulfuric acid is obtained after reason, is discharged into acid mixing device and is used to adjust dry suction finished product sulfuric acid concentration.
