Abstract
The utility model discloses a multi-effect cyanide-bearing waste water vacuum evaporation and recovery device, which includes a tower body with a mixed acid chamber in an upper space thereof, a spray packing chamber which is connected with a high efficient material receiving cylinder is arranged under the mixed acid chamber, a deposit chamber is disposed below the material receiving cylinder, and the lower part of the deposit chamber is a thickening cone. The vacuum evaporation and recovery device has a simple structure and can implement the multi-effect vacuum evaporation and recovery at a time with the recovery rate of 99 percent. The evaporation and recovery device avoids the problems of high treatment cost and secondary pollution in the exiting process of cyanide-containing wastewater treatment and achieves the goal of changing waste into valuables. Cyanide-containing wastewater can be directly recycled and reutilized, thereby greatly saving costs and energy and protecting the environment.
Description
Technical field
The utility model relates to a kind of cyanogens-containing sewage water retrieving arrangement.
Background technology
The existing history that goes up a century of extraction of gold by cyanidation is that gold mine is put forward golden topmost method always.Two kinds of different cyanidation technologies are arranged at present, and promptly two kinds of methods of zinc cyanide powder substitution depositing technology and carbon slurry process all produce the waste water that contains a large amount of prussiates.Because prussiate is hypertoxic, therefore, cyaniding gold extraction waste water should be deviate from deleterious prussiate before discharging, make its emission standard that reaches regulation, just can enter water drain or small stream korneforos, and handling the back index must be definitely up to standard; If the not treated water body that enters will cause severe contamination, and cyano complex influence the further processing of waste water, therefore at first will remove the prussiate in the waste water, handles water-quality determination afterwards and just can be for further processing after up to standard.The common treatment process of cyanide wastewater has alkaline chlorination process, electrolytic process, ion exchange method, activated carbon method etc.These methods are not weak effects, are exactly the cost height, and what have also exists secondary pollution and influence recycling of water body because of adding chemical.At present, also be not exclusively used in the treatment unit that reclaims cyanogens-containing sewage water.
The utility model content
The purpose of this utility model is to provide a kind of cyanogens-containing sewage water multiple-effect vacuum evaporation retrieving arrangement, to reach the purpose that turns waste into wealth.
To achieve these goals, the technical solution of the utility model is to have adopted a kind of cyanogens-containing sewage water multiple-effect vacuum evaporation retrieving arrangement, comprise tower body, the upper space of tower body is the nitration mixture chamber, the below of nitration mixture chamber is spray filler chamber, spray filler chamber links to each other with efficiently being subjected to barrel, efficiently is subjected to the barrel below to be the settling chamber, and the bottom, settling chamber is for concentrating the awl bucket.
Be provided with sulfuric acid inlet and cyanogens-containing sewage water inlet on the top of nitration mixture chamber.
The vacuum pumping chamber outlet is arranged on the tower body top.
Described concentrated awl bucket outer setting has a steam heating water jacket.
The precipitation bucket lower end, bottom that concentrates the awl bucket is provided with plasma discharge mouth and condensation-water drain.
On the precipitation bucket sidewall, also be provided with inspection manhole.
The described barrel that efficiently is subjected to links to each other with an efficient tilted plate, efficiently is being subjected to be provided with overflow weir around the barrel, and the discharge weir is connected with leakage fluid dram on the tower body.
Described tower body is provided with the vacuumometer scale.
Utilize retrieving arrangement of the present utility model, under the negative pressure of vacuum effect, cyanogens-containing sewage water and sulfuric acid suck the nitration mixture chamber in the tower body certainly via cyanogens-containing sewage water inlet, the sulfuric acid inlet on vacuum-evaporation recovery tower top respectively, behind the thorough mixing, mixing liquid is sprayed by spray piping, enters filler chamber, during chemical reaction takes place, complexing cryanide ion in the cyanogens-containing sewage water and the reaction of the hydrogen ion in the sulfuric acid generate prussic acid promptly: (CN)
-+ H
+=HCN ↑, HCN evaporates, and owing to the effect of negative pressure of vacuum, evaporable prussic acid is inhaled in the vacuum jet pump simultaneously, and prussic acid and alkali reaction absorb, and generate liquid sodium cyanide (HCN+NaOH=NaCN+H
2O), return cyanidation gold-extracted process and be used again, thereby reached the purpose that sodium cyanide is reclaimed in the full acidifying of cyanogens-containing sewage water.For accelerating chemical reaction and velocity of evaporation, concentrate awl and following partial design steam heating water jacket, production process can be carried out the steam heating operation.
Apparatus structure of the present utility model is simple, and a multiple-effect vacuum-evaporation is reclaimed, and the rate of recovery reaches 99%.Avoid the processing cost height that caused in the existing processing cyanogens-containing sewage water process, caused secondary pollution problem easily, reached the purpose that turns waste into wealth.Cyanogens-containing sewage water directly reclaims and utilizes again, has saved cost greatly, energy-conserving and environment-protective.
Description of drawings
Fig. 1 is the structural representation of retrieving arrangement of the present utility model.
Embodiment
As shown in Figure 1, retrieving arrangement of the present utility model comprises tower body 1, the upper space of tower body 1 is nitration mixture chamber 2, the below of nitration mixture chamber 2 is spray filler chamber 3, spray filler chamber 3 links to each other with efficiently being subjected to barrel 4, and efficiently being subjected to barrel 4 belows is settling chamber 5, and 5 bottoms, settling chamber are for concentrating awl bucket 6, concentrating awl bucket 6 outer setting has a steam heating water jacket 7, to accelerate chemical reaction and velocity of evaporation.Tower body is provided with vacuumometer scale 15, is provided with sulfuric acid inlet 8 and cyanogens-containing sewage water inlet 9 on the top of nitration mixture chamber 2, and vacuum pumping chamber outlet 10 is arranged on tower body 1 top.Bottom precipitation bucket 11 lower ends that concentrate awl bucket 6 are provided with plasma discharge mouth 12 and condensation-water drain 13, also are provided with inspection manhole 14 on precipitation bucket 11 sidewalls.Linked to each other with an efficient tilted plate 16 by barrel 4, efficiently be subjected to be provided with overflow weir 17 around the barrel 4, discharge weir 17 is connected with leakage fluid dram 18 on the tower body.Liquid such as the cuprous rhodanide that generates in the reaction process enter into settling chamber, bottom 5 by the efficient material feeding tube 4 in center, clarify precipitation; Liquid is fed by the efficient material feeding tube 4 in center, through efficient tilted plate 16, behind the peripheral overflow weir 17, is clear liquor and overflows, and enters the reaction of neutralization reaction groove, and back up to standard is from liquid outlet 18 dischargings; The solid precipitations such as cuprous rhodanide that generate are gone into precipitation bucket 11 through concentrating awl bucket 6, at last by being pumped into the pressure filter press filtration, forming copper cake and sell outward.
