| titleOfInvention | Device and method for purifying residual HCN (hydrogen cyanide) through electro-Fenton |
| abstract | The invention discloses a device and method for purifying residual HCN (hydrogen cyanide) through electro-Fenton. The device comprises a waste gas collecting hood, a pressure controller, an electric waste gas processing device, an HCN recovery storage tank, a gas mist eliminator, a spray liquid storage pool, a control valve, a on-line monitor, an anolyte collection pool, a catholyte tank, a Fe2+ containing liquid tank, a cathodic electro-Fenton device, a first anode plate, a first cathode plate, a first direct-current power supply, a conducting medium, a gas cylinder and a blower. High-concentration cyanogen-containing waste gas passes through the electric waste gas treatment device firstly so as to recover most of HCN, then the residual low-concentration HCN gas is fed into the cathodic electro-Fenton device, the cathodic electro-Fenton device is a fluidized bed type device and is internally filled with the conducting medium, voltages are exerted on the two ends of the device, Fe2+-containing liquid is fed in the device, and air is fed in a cathode, so that free radicals are generated under the action of electricity, and then low-concentration HCN is oxidized into CO2, thereby realizing the zero release of HCN. The device can treat various cyanogen-containing waste gases such as carbon fiber tail gas, acrylic cyanide waste gas and the like. |
