Problems solved by technology

This not only wastes manpower and material resources, but also wastes time, resulting in low output and heavy labor, and impurities will be doped in the iron filings, which will be discharged along with the ferric chloride steam during the reaction, so that the purity of ferric chloride will decrease.

Embodiment 1

[0032] A melting and chlorination furnace for producing ferric chloride comprises a melting furnace 1 and a chlorination furnace 2, and the chlorination furnace 2 includes a chlorine gas inlet 3, a molten iron inlet 4 and a ferric chloride steam outlet 5, the The ferric chloride steam outlet 5 upper end is connected with a rotary separation zone 21, a spiral shaft 22 is provided in the rotary separation zone 21, a separation port 23 is provided on the side wall of the bottom end of the rotary separation zone 21, and an air outlet 24 is provided at the top. The melting furnace 1 includes a bracket, an iron filings inlet 6 and a molten iron outlet 7, the iron filings inlet 6 is connected to the separation port 23, and the molten iron outlet 7 on the melting furnace 1 passes through the molten iron inlet 4 on the chlorination furnace 2 The pipeline 8 is connected, and the support includes a fixed support frame 9 and a movable support frame 10. The upper end of the fixed support fr...

Embodiment 2

[0037] A production process for ferric chloride, comprising the steps of:

[0038] (1) Add 600Kg iron filings into the melting furnace in the melting chlorination furnace, and heat up to melt the iron filings;

[0039] (2) Feed chlorine gas into the melting chlorination furnace, open the gate at the outlet of molten iron, extend the oil cylinder of the movable support rod, tilt the melting furnace, and make the molten iron flow into the chlorination furnace to contact with chlorine gas;

[0040](3) The ferric chloride vapor generated by the reaction is separated from solid and gas through the rotating separation zone in the chlorination furnace of the melting chlorination furnace, and the separation port is opened to return the separated solid to the melting furnace for re-melting to improve the utilization rate of iron filings; It is sucked into three traps by the negative pressure of the exhaust fan for cooling and crystallization;

[0041] (4) Tail gas absorption is divide...

Embodiment 3

[0044] Add 600Kg of iron filings directly to the chlorination furnace to burn the iron filings red. The amount of chlorine added is 1.7 times the amount of iron filings, that is, 1020Kg. The reaction temperature is 1000°C. The reaction furnace is negative pressure, about 200mm water column, and the final reaction The temperature is 450-500°C, and the ferric chloride vapor generated by the reaction is sucked into the trap by the negative pressure of the exhaust fan for cooling and crystallization. After cooling by three traps, the tail gas absorption is divided into three steps: the first and second absorption towers use ferrous chloride solution to absorb and react to generate ferric chloride solution; the third absorption tower is sodium hydroxide The solution absorption tower uses lye to absorb the chlorine gas that is not completely absorbed in the first and second steps, so as to meet the emission standard of waste gas.

[0045] Detect the purity of ferric chloride and the...
