摘要（英）：

A device for purifying and liquefying hydrocyanic acid and producing sodium cyanide with hydrocyanic acid in combination with cyanide-containing exhaust gas comprises an ammonia removal tower, a hydrocyanic acid precooler, a steam-water separator, a hydrocyanic acid dehydrator, a hydrocyanic acid condenser, a liquid hydrocyanic acid collecting tank and a sodium cyanide absorbing tower, wherein the liquid outlet of the ammonia removal tower is connected with a deaminized liquid circulating pump through a valve II and a deaminized liquid cooler, and the ammonia removal tower and an ammonium sulfate storage trough are respectively connected with the outlet end of the deaminized liquid circulating pump; a liquid discharging pipe at the bottom of the steam-water separator is connected with the ammonia removal tower; sulfuric acid enters the ammonia removal tower through the hydrocyanic acid dehydrator; liquid caustic soda enters the sodium cyanide absorbing tower through a sodium cyanide spray transferring pump, and the sodium cyanide absorbing tower is connected with a sodium cyanide product storage trough through the sodium cyanide spray transferring pump. The liquid hydrocyanic acid is obtained through ammonia removal, pre-cooling, dehydrating and condensation liquefying and is used for producing sodium cyanide in combination with the cyanide-containing exhaust gas.
