| titleOfInvention | Remove the method and system of the HCN in sulphur ammonium |
| abstract | The invention provides a kind of method and system that remove the HCN in sulphur ammonium, method comprises the steps: the ammonium sulfate solution of production to be delivered to heat exchanger; Carry out flash distillation with sending into decyanation still after ammonium sulfate solution described in Steam Heating; Steam after flash of steam and HCN enter HCN and recycle pipeline, and HCN is recycled; Described system comprises sulphur ammonium circulating tank, sulphur ammonium heater, decyanation still, cyclone separator; The present invention is by utilizing the characteristic of easily overflowing from solution under HCN boiling point low and high temperature condition; the mode that adopts a kind of flash distillation is by vaporize decyanation the HCN removing is recycled of ammonium sulfate solution; by integrated to sulphur ammonium decyanation operation and hydrogen cyanide synthesis procedure; solve a gas not tractable difficult problem in the ordinary course of things that contains HCN after flash distillation; reduce the production cost of HCN; can reduce again the evaporation of sulphur ammonium and emit the pollution that HCN tail gas brings simultaneously, significant to changing waste into resources utilization and environmental protection. |
