Technology and system for improving yield of nitric acid regenerated by stainless steel acid-washing waste liquid

The invention relates to a technology and a system for improving the yield of nitric acid regenerated by stainless steel acid-washing waste liquid. After the acid-washing waste liquid is concentratedby high-temperature flue gas in a pre-concentrator, the acid-washing waste liquid enters a hydrolysis and roasting furnace to be decomposed at high temperature; after flue gas containing HF, NOx and HNO3 enters the pre-concentrator and is subjected to dust removal and cooling, the flue gas enters an acid absorption tower to be subjected to acid absorption; then the flue gas is washed through a washing tower and is condensed by circulating cooling water in a condenser; condensed liquid is used as washing liquid to participate in washing in a washing tower; the washed washing liquid is used as absorption liquid of an acid absorption tower; the condensed gas enters a catalytic denitration device to be subjected to denitration reaction; after the NOx is removed, the flue gas is discharged after reaching the standards. By adopting the technology and the system, the flue gas is cooled before being subjected to the acid absorption, so that the absorption rate of the nitric acid is effectivelyimproved; meanwhile, an oxidant is sprayed into the flue gas and NO can be oxidized into high-valence substances including N2O5 and the like, so that the yield of the nitric acid is improved.
