Efficiency Environmental Protection Three Way Catalyst DC Furnace

Three-way catalyst DC furnace

Equipment use: Mainly used for smelting raw materials automotive catalyst (80%) and petroleum catalyst slag (20%) treatment, the equipment adopts direct current mode, effective recovery of valuable metals.
Process mode: DC electric furnace, the process is simple, high efficiency.

Equipment Description - Technical features of DC furnace equipment:
1) DC electric arc furnace than AC furnace heat transfer efficiency is high, electrode consumption is much less than AC furnace, simple operation, convenient maintenance.
2) The temperature of the reaction zone of the molten pool is high, the temperature of the solution at the bottom of the furnace is uniform, the furnace eye is easy to open, and the iron is smooth.
3) The furnace bottom conductive structure is simple, reliable operation, convenient installation and maintenance.
4) The heat is concentrated, the crucible area of the melting pool is close to the bottom of the furnace, and the heat radiation of the solution slag line area is small, which has a good protection effect on the protection of resistant materials.
5) The DC electric furnace has a low flicker effect and noise, which is very beneficial to the power grid and the operator, and its flicker effect is only 50% to 70% of the AC electric furnace, and the noise during submerged arc operation is more than 20dB lower than that of the AC electric furnace.
6) The natural power factor of DC electric furnace is high, and the power factor can reach 0.90~0.96 without compensation.
7) The integrated rectifier power supply adopts a three-phase full-bridge rectifier device, and the AC power supply is rectified into a stable and reliable DC power supply. Heating mode of DC arc furnace in furnace. The rectifier device is cooled by independent closed cooling equipment, which is safe and reliable.
8) The electrode lifting control adopts PLC hydraulic proportional reversing valve mode + manual priority operation mode, and implements voltage and current double closed-loop control. The use of internationally renowned low-voltage electrical components (Siemens/Schneider), effectively ensure the reliability and advanced nature of the equipment.
9) Advanced computer operating system, real-time operation and operation management of operation process and operation parameters.
