Description
技术领域：Technical field:
本实用新型属于机械领域，涉及管材内部酸洗的设备，尤其是一种大型管材内部酸洗装置。The utility model belongs to the field of machinery and relates to equipment for pickling inside pipes, in particular to a pickling device inside large pipes.
背景技术：Background technique:
酸洗是指利用酸溶液去除钢铁表面上的氧化皮和锈蚀物,是清洁金属表面的一种方法。通常与预膜一起进行。利用氧化皮、铁锈等铁的氧化物(Fe3O4，Fe2O3，FeO等)与酸溶液发生化学反应，形成盐类溶于酸溶液中而被除去的原理，将制件浸入硫酸等的水溶液，以除去金属表面的氧化物等薄膜。是电镀、搪瓷、轧制等工艺的前处理或中间处理。Pickling refers to the use of acid solution to remove scale and rust on the steel surface, and is a method of cleaning metal surfaces. Usually done with pre-film. Using the principle that iron oxides (Fe 3 O 4 , Fe 2 O 3 , FeO, etc.) such as scale and rust react with acid solution to form salts that are dissolved in acid solution and removed, the workpiece is immersed in sulfuric acid Etc. aqueous solution to remove thin films such as oxides on the metal surface. It is the pretreatment or intermediate treatment of electroplating, enamel, rolling and other processes.
酸洗工艺主要有浸渍酸洗法、喷射酸洗法和酸膏除锈法。一般多用浸渍酸洗法，大批量生产中可采用喷射法，内流动酸洗属于浸渍酸洗法的范畴。The pickling process mainly includes immersion pickling, spray pickling and acid paste rust removal. Generally, the immersion pickling method is mostly used, and the spray method can be used in mass production. The internal flow pickling belongs to the category of the immersion pickling method.
但无论是何种方式的酸洗，在酸洗过程中，主要通过酸与金属皮的化学反应，溶解相应的金属氧化物的溶解作用来除去金属皮。而如使用硫酸等进行钢材酸洗时，还要借助于酸与金属发生化学反应产生的氢气泡的剥离作用来除去氧化皮。因此在酸洗过程中，大量消耗酸是必然的。But no matter what kind of pickling, in the pickling process, the metal skin is mainly removed through the chemical reaction of acid and metal skin, and the dissolution of the corresponding metal oxide. And if sulfuric acid is used to pickle steel, it is necessary to remove the scale by means of the stripping effect of hydrogen bubbles generated by the chemical reaction between acid and metal. Therefore, in the pickling process, it is inevitable to consume a large amount of acid.
而单独针对大型管材的浸渍酸洗，将管材完全浸渍势必消耗海量的酸液，产生巨额的成本。当酸液中的金属离子和其它无机杂质达到一定的浓度后，因处理效果达不到工艺要求，酸液需要重新配制和更换。在这个过程中，大量的废酸液被产生。这些废酸液中由于含有较高浓度的酸和金属，对环境造成一定的威胁，需要进行处理。在处理过程中，大量残余的酸被浪费，进一步增加了生产成本。However, for the impregnation and pickling of large pipes alone, it is bound to consume a large amount of acid solution to completely impregnate the pipes, resulting in huge costs. When the metal ions and other inorganic impurities in the acid solution reach a certain concentration, the acid solution needs to be re-prepared and replaced because the treatment effect cannot meet the process requirements. During this process, a large amount of spent acid is produced. Due to the high concentration of acid and metal contained in these waste acid liquids, it poses a certain threat to the environment and needs to be treated. During processing, large amounts of residual acid are wasted, further increasing production costs.
