Evaporation

The evaporation technology is one of the most applied methods in environment protection fields.

The evaporation system is usually used for impurities processing in sewage acid, and the waste is collected together through evaporation and separation of HCL and water. The regular applied evaporation processes including single effect evaporation, multi-effect evaporation and MVR evaporation. Different mediums require different evaporation types.

The Graphite evaporation device could replace the traditional reactor evaporation process, improve the evaporation efficiency and reduce steam consumption. It could be used to concentrate mediums with low acid concentration including sulfuric acid.

MVR cases:

1.MVR evaporation & crystallization plant:solid waste resource utilization project, which separate Nacl and Naso4,and then evaporation crystallization respectively to get salt.

2.MVR evaporation & crystallization plant:Circuit board recycling etching solution by-product resource utilization project, ammonium chloride evaporation crystallization to obtain crystal ammonium chloride products

3.MVR evaporation & crystallization plant:Desul phurization waste liquid of power plant is treated by evaporation and crystallization of high-salt waste liquid to achieve zero discharge

4，Four evaporation & crystallization plant:In the biological fermentation waste liquid treatment project, the waste liquid of high salt and COD will evaporate and crystallize, and the mother liquid will be dried to achieve the purpose of zero discharge

5，Four evaporation & crystallization plant:For the chemical waste liquid treatment project, the waste liquid of high salt and COD will evaporate and crystallize, and the mother liquid will be dried to achieve the purpose of zero discharge

6.Three evaporation & crystallization plant:The waste liquid treatment project of pharmaceutical factory will evaporate and crystallize the waste liquid of high salt and COD, recover the organic matter with low boiling point, and dry the mother liquor to achieve the purpose of zero discharge

7，Three evaporation & crystallization plant:Metallurgical smelting waste liquid treatment project, the high salt waste liquid evaporation crystallization, in order to achieve zero discharge
