Abstract
The utility model relates to environmental protection industry (epi) technical field, be particularly related to a kind of retrieving arrangement of stainless steel acid-washing waste liquid, comprise spent acid storage tank, calcination device and liquefied room, spent acid storage tank is connected with the left side import of calcination device by pipeline, the air outlet, top, right side of calcination device is connected with liquefied room by pipeline, and described calcination device bottom is connected with metal recovery pond by pipeline; Liquefied room's inner chamber is provided with cool-heat-exchanger.In the time using the utility model, by calcination device, spent acid is carried out to gas phase separation, isolate acid vapour and metallic crystal body; Acid vapour is cooled to concentrated acid liquid through liquefied room, after metallic crystal body is cooling, leaves metal recovery pond in, so just spent pickle liquor fully can be recycled, and has solved environmental issue.The utlity model has simple in structurely, arrange rationally, the advantage such as cost of manufacture is low.
Description
Technical field
The utility model relates to environmental protection industry (epi) technical field, particularly a kind of retrieving arrangement of stainless steel acid-washing waste liquid.
Background technology
Pickling is requisite operation in producing stainless steel process, both ensured the quality that steel surface is good, be again that further deep processing is ready " according to " Iron And Steel Industry " 12 " development program "; expect 2015; China's stainless steel annual requirement is 1.6Mt; therefore will produce a large amount of stainless steel acid-washing waste liquids (hereinafter to be referred as spent pickle liquor) every year, and the every loss per ton steel fresh water amount of planning requirement is lower than 4.0m
3, solid waste comprehensive utilization ratio, more than 97%, contains water and the metal ion of a large amount of reusable edibles in addition in spent pickle liquor, and therefore the recycling of spent pickle liquor is very urgent.
Utility model content
The purpose of this utility model is for the defect of prior art and deficiency, provides a kind of simple in structure, the retrieving arrangement of stainless steel acid-washing waste liquid reasonable in design, easy to use.
For achieving the above object, the technical solution adopted in the utility model is:
The retrieving arrangement of a kind of stainless steel acid-washing waste liquid described in the utility model, comprise spent acid storage tank, calcination device and liquefied room, spent acid storage tank is connected with the left side import of calcination device by pipeline, the air outlet, top, right side of calcination device is connected with liquefied room by pipeline, and described calcination device bottom is connected with metal recovery pond by pipeline; Liquefied room's inner chamber is provided with cool-heat-exchanger.
Further, the cross section of described cool-heat-exchanger is cross shape.
Further, described calcination device top is provided with explosion trap.
Further, described liquefied room is connected with dilution chamber by pipeline, and described dilution chamber top is provided with diluent import, and described dilution chamber bottom is connected with acid solution pond for recovering by pipeline.
Adopt after said structure, the utility model beneficial effect is: the retrieving arrangement of a kind of stainless steel acid-washing waste liquid described in the utility model, comprise spent acid storage tank, calcination device and liquefied room, spent acid storage tank is connected with the left side import of calcination device by pipeline, the air outlet, top, right side of calcination device is connected with liquefied room by pipeline, and described calcination device bottom is connected with metal recovery pond by pipeline; Liquefied room's inner chamber is provided with cool-heat-exchanger.In the time using the utility model, by calcination device, spent acid is carried out to gas phase separation, isolate acid vapour and metallic crystal body; Acid vapour is cooled to concentrated acid liquid through liquefied room, after metallic crystal body is cooling, leaves metal recovery pond in, so just spent pickle liquor fully can be recycled, and has solved environmental issue.The utlity model has simple in structurely, arrange rationally, the advantage such as cost of manufacture is low.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1-2, the retrieving arrangement of a kind of stainless steel acid-washing waste liquid described in the utility model, comprise spent acid storage tank 2, calcination device 3 and liquefied room 4, spent acid storage tank 2 is connected with the 3 left side imports of calcination device by pipeline 1, the air outlet, top, right side of calcination device 3 is connected with liquefied room 4 by pipeline 1, and described calcination device 3 bottoms are connected with metal recovery pond 6 by pipeline 1; Liquefied room's 4 inner chambers are provided with cool-heat-exchanger 8.
As a kind of optimal way of the present utility model, the cross section of described cool-heat-exchanger 8 is cross shape; Can improve like this liquefaction effect.
As a kind of optimal way of the present utility model, described calcination device 3 tops are provided with explosion trap 3-1, can improve like this security of calcination device 3.
As a kind of optimal way of the present utility model, described liquefied room 4 is connected with dilution chamber 5 by pipeline 1, and described dilution chamber 5 tops are provided with diluent import 5-1, and described dilution chamber 5 bottoms are connected with acid solution pond for recovering 7 by pipeline 1; Can allow like this concentrated acid be reclaimed fully.
In the time using the utility model, by calcination device, spent acid is carried out to gas phase separation, isolate acid vapour and metallic crystal body; Acid vapour is cooled to concentrated acid liquid through liquefied room, after metallic crystal body is cooling, leaves metal recovery pond in, so just spent pickle liquor fully can be recycled, and has solved environmental issue.In addition, this is simple in structure, reasonable in design, low cost of manufacture.
The above is only preferred embodiments of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
