Description
Technical field
The utility model is related to a kind of acid dip pickle that can effectively suppress acid mist generation and uses technique, belongs to atmospheric environment
Protect apparatus field.
Background technology
The problems such as having to removal metal oxide layer and rust deposite is frequently encountered in the production process of metal and its product.
Pickling can effectively remove metal oxide layer and rust deposite, be the method that can effectively solve the problem that problem above the most frequently used at present.Acid
Washing common acid has hydrochloric acid, sulfuric acid, nitric acid, hydrofluoric acid and mixed acid etc., during pickling, due to the gas of chemical reaction generation
The volatilization of body or acid solution itself, some tiny acid solution drops being brought into, acid mist is formed in air, the body of serious harm workman
Body health, etching apparatus, and air is polluted.So being improved to existing acid cleaning process, make it in pickling
Do not produce acid mist significant in journey.
Acid cleaning process mainly has dip pickling method, injection acid wash and sour cream rust removal method, general multiplex infusion process.It is near
Year, during acid cleaning process is also at constantly development and improves, it is concentrated mainly on acid dip pickle and suppresses acid mist method aspect.China
Patent CN103451669A discloses the acid-washing stainless steel mist inhibition system and acid cleaning process of a kind of pickling circulation.The method is to pass through
By acid solution and vapor, the quick mixing in descaling bath reaches the effect being rapidly heated to acid cycle pump, while being added using fog inhibitor
The gas that medicine air dissolved pump dissolves in discharges a large amount of microbubbles in acid tank, and point of safes froth bed is formed on acid tank surface, while acid solution
Recycling can make froth bed rapid regeneration and recycle.The technique reduces thermal loss, pickling efficiency is improved, while effectively
Reduce the generation of acid mist.But foam in hibitors easily catches the hydrogen and oxygen of acid cleaning process generation, blast mixing is reached
Point.Meanwhile, foam fog inhibitor is unstable and use of foam fog inhibitor can influence pickling effect.Chinese patent CN203768462U
Report a kind of closed acid mist recycling and processing device, the complete equipment by input and output material, pickling, help the equipment such as plating to be placed in a closing
Space in, and electric block and track are provided with above equipment, for lifting material.Material is from material when the complete equipment runs
Hole bottom bypasses partition panel and enters confined space, it is to avoid take acid mist out of, and the acid mist produced in acid cleaning process concentrates on closing sky
Between, by air-introduced machine after acid mist passage is extracted into the treatment absorption of acid mist spray column, organized qualified discharge.Although the complete equipment
Have collected acid mist and subsequently carry out drip washing absorption treatment, but the device program is various, and equipment is complicated, and at no solution acid mist
Relatively costly and acid mist etching apparatus the problem of reason.Chinese patent CN202430291U reports a kind of for galvanizing production work
Step-by-step movement automation pickler in skill, the equipment is in a workshop for the closing equipped with walking hoisting traveling crane, to pass through
Acid cleaning process automatically controls programming to realize pickling stepping automated job.The equipment not only effectively raises galvanizing life
The mechanization of product, automaticity, improve operating efficiency and realize the separation of pickling zone equipment and acid gas, protect and set
It is standby.But internal mechanical complex operation, invests many, and power consumption is big, and the acid gas collected needs subsequent treatment, increases production cost.
Chinese patent CN103451669A discloses a kind of polymer microballoon and suppresses the method that acid mist is produced, and the method uses polymer
Microballoon carries out all standing to acid solution surface, can effectively suppress the formation of acid mist, with good suppression acid mist effect.Ding Li
Deng（Application [J] of fog inhibitor with ball float in acid cleaning process is modern metallurgical, and 1995 (2):44-47.）Describe H-2 acid mists
The application of fog inhibitor and the solid ball floats of PP in pickling, experiment shows that two methods can effectively suppress acid mist, but workpiece
When acid solution is passed in and out, meeting adhesive tape acid fog inhibitor foam and the solid ball floats of PP are, it is necessary to secondary cleaning is processed.So H-2 acid mists suppress
It is a rational selection that agent and PP ball floats combine elution device to be applied in acid cleaning process.
Existing acid cleaning process, only payes attention to the effect of production cost and pickling mostly, and to the acid of generation in acid cleaning process
Mist pollutes and harm payes attention to inadequate.In terms of acid mist suppression, or the local generation for suppressing acid mist, or to having produced
Acid mist carries out other treatment, all can not fundamentally suppress the generation of acid mist.Method of the present utility model overcomes existing side
The shortcoming of method, employs the mode that totally-enclosed submersible is sent into pickling tube by workpiece, and with cascade, cover plate and polymer microballoon pair
Acid solution carried out it is totally-enclosed, therefore, diffusion of the acid mist to air is effectively prevented in whole acid cleaning process.Meanwhile, this reality
Acid solution is further comprises with new technique and purify reuse means, can be greatly enhanced the utilization ratio of acid solution, be greatly lowered
The discharge rate of spent acid.With existing process ration, technique of the present utility model is also with simple to operate, pickling efficiency high, section
About resource, subsequent treatment be few and the low distinguishing feature of operating cost.
