Description

A kind of sulfuric acid waste reclaiming clean device
Technical field
The utility model 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.
Utility model content
The purpose of this utility model is that a kind of sulfuric acid waste reclaiming clean device is provided the problem of presence for prior art.
Concrete technical scheme of the present utility model is as follows:
A kind of sulfuric acid waste reclaiming clean device, including it is purifying column, degassing tower, sour water storage tank, filter press, concentration tower, mixed Sour device and tail inhale tower, and the purifying column discharging opening is connected by slush pump with degassing tower charging aperture, degassing tower discharging opening and sour water Reservoir inlet is connected, and sour water reservoir outlet is connected by filter pressing pump with feed opening of press filter, filter press discharging opening and concentration Tower charging aperture is connected, and concentration tower discharging opening is connected with acid mixing device;It is negative that exhaust outlet, the degassing tower exhaust outlet of purifying column are connected to purification Flue is pressed, the exhaust outlet of concentration tower is connected to tail and inhales tower;
The reverse jet tube of the concentration tower is connected with two suction tower exhaust pass.
The utility model has the advantages that:
The utility model can carry out effective purified treatment to sulfuric acid waste, effectively can reclaim in sulfuric acid waste Sulfuric acid components, finished product sulfuric acid concentration is inhaled for adjusting to do, caused waste residue amount is extremely low after purified treatment, and can effectively return Receive valuable metal therein.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
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.
The utility model specific work process is as follows:
Sulfur-bearing acid waste liquid enters purifying column 1, is mixed the mud in waste liquid and liquid by the vortex separating tube of purifying column 1 Even, caused sulfur dioxide gas is discharged into recycling in purification negative pressure flue in purifying column 1, is well mixed in purifying column 1 Waste liquid delivered into by slush pump 8 in degassing tower 2 and be de-gassed operation, the sulfur dioxide gas in waste liquid is discharged into purification Recycling in negative pressure flue, the waste liquid after degassing process, which enters in sour water storage tank 3, to be stored, useless in sour water storage tank 3 Liquid delivers into filter press 4 by filter pressing pump 9, and filter press 4 carries out separation of solid and liquid, and obtained solid waste can carry out valuable metal Recovery, obtained sour water clear liquid, which is delivered in concentration tower 5, carries out concentration, meanwhile, two inhale tower exhaust pass 11 to concentration tower 5 Reverse jet tube in conveying dry flue gas, take away part water, fluorine, chlorine in sour water clear liquid, into tail inhale tower 7 absorbed, concentration tower 5 Dilute sulfuric acid is obtained after concentration, is discharged into acid mixing device and is used to adjust dry suction finished product sulfuric acid concentration.
