How to deal with waste hydrochloric acid iron and steel industry, fabricated metal products in the production process need to remove the steel surface oxide skin using hydrochloric acid pickling process will produce a lot of waste acid, hydrochloric acid pickle liquor main constituents: free acid, ferrous chloride and water. Its content with the pickling process, operating temperature, steel materials, specifications vary, generally Ferrous Chloride: 20-26%, free acid: 5-8%, the rest is water. Such amazing waste of emissions, the general production of a tonne of steel pickling liquid waste produces about 55-72kg. Currently the steel industry has become a major water users, but also generate large waste. According to statistics, dilute hydrochloric acid, only the key steel enterprises have an annual volume of wastewater discharged more than 30 billion cubic meters. For this type of waste treatment, mainly in two ways: First, the acid-base neutralization method, the second is hydrochloric acid regeneration. Hydrochloric acid regeneration are used heating evaporation, spray combustion mode, the current domestic hydrochloric acid regeneration system is introduced, the process is directly heated recycle waste acid and hydrochloric acid, iron oxide, few large-scale iron and steel enterprises to adopt laws and Lurgi Lu Tena law. The treatment process time investment, operation and maintenance costs high, serious damage to the equipment, SMEs generally unbearable. Therefore, most of the domestic small and medium enterprises using lime neutralization, the spent acid during and after discharge. However, this method consumes a large amount of lime, and produce large amounts of moisture content of 99% of the sludge drying process required. The approach to infrastructure investment and handling costs are also high, and the waste acid in a useful resource for failure to recycling. To this end, we have gone through years of experiments, research, the vacuum evaporation process dilute hydrochloric acid and hydrochloric acid waste recycling process for ferrous chloride crystals. Our responsibility to our customers believe that customers' success is our success! We are the best customers trusted partner of hydrochloric acid gas treatment method hydrochloric acid, the scientific name as hydrochloric acid, hydrogen chloride. (Chemical formula: HCl) in aqueous solution, it is a monobasic acid. Hydrochloric acid is a strong acid, hydrochloric purpose, concentrated hydrochloric acid is extremely volatile, and therefore a container filled with concentrated hydrochloric acid mist after the opening at the top can see, it is a small volatile hydrochloric acid to produce hydrogen chloride in combination with water vapor in the air droplets. Hydrochloric acid is a common chemical, in general, concentrated hydrochloric acid, hydrogen chloride content of about 37%. At the same time, the main component of acid is hydrochloric acid. Hydrochloric acid is corrosive, University Road hydrochloric acid, many people do not know how to deal with the rest of the hydrochloric acid, the following small series to introduce you to a way to ensure safe and effective. Hydrochloric acid is a strong acid, concentrated hydrochloric acid is extremely volatile, and therefore a container filled with concentrated hydrochloric acid mist after the opening at the top can see, it is produced in combination with the volatile hydrogen chloride vapor in the air droplets of hydrochloric acid. If you want to dispose of hydrochloric acid, you only need to lye - lime and, after discharge into the wastewater system generates sodium chloride and calcium chloride, can be diluted with water wholesale hydrochloric acid, Zhengzhou Longda Chemical, University Road hydrochloric acid. provided by the Zhengzhou Longda Chemical Products Co., Wholesale hydrochloric acid, Zhengzhou Longda Chemical, University Avenue hydrochloride Zhengzhou Longda Chemical Products Co., Ltd.
