In China's many industrial sectors widely used acid cleaning process, in metal acid cleaning process, with the acid cleaning operation continuing to take place, the concentration of acid wash continues to decrease, while the acid wash content of metal ions continues to rise, when the acid wash concentration is low to below the specified value, or the acid wash content of metal ions exceeds the allowed limit value above, when the acid wash loses acid cleaning effect, becomes waste acid, this waste acid can't be used, according to the national environmental protection regulations or not allowed direct emission, is a difficult problem to deal with.
Evaporation method waste acid regeneration device, can extract from waste hydrochloric acid crystal, which is a valuable chemical raw material, can be sold in the market, while getting the same as the original waste acid concentration, without iron salt pure hydrochloric acid, after alloying acid adjusted concentration can be put back into use in acid washing. No waste water emissions during recycling process, nor any secondary pollutants produced, not only solved environmental protection problems, but also has a considerable economic benefit.

The principle of evaporation method waste acid regeneration treatment is based on waste acid chloride in waste acid liquid is very difficult volatile solid phase substances, in the process of waste acid evaporation, these metal salts always remain in acid liquid, in secondary steam almost no contain subferrous chloride and other substances, therefore after evaporation obtained secondary steam condensation, i.e. regenerated hydrochloric acid, will also not contain metal salts of substances, getting is pure hydrochloric acid, can be put into acid washing and reuse.
