The utility model provides a kind ofly is used for acid washing iron red high temperature purification equipment, through adopting above structure, feeds water vapour, thereby has reduced temperature of reaction, has original 800-900 ° to be reduced to present 300-650 °, thereby has reduced energy consumption effectively.And the chloride ion content of finished product materials further reduces, and is merely below 0.10%; Tail gas just can discharge after all reclaiming through the hydrogen chloride gas recovery system, has reduced pollution effectively.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Fig. 1 is the one-piece construction synoptic diagram of the utility model.
Among the figure: feed system 1, one-level is handled kiln 2, second-stage treatment kiln 3, cooling tube 4, material packing plant 5, circulating cooling system 6, hydrogen chloride gas recovery system 7, water vapour interface 8.
Embodiment
In Fig. 1, a kind ofly be used for acid washing iron red high temperature purification equipment, comprise processing kiln, feed system 1 that multistage head and the tail connect, be positioned at the cooling tube 4 of handling the kiln outlet and be connected with circulating cooling system 6; Described processing kiln at different levels is an all-sealed structure, and processing kilns at different levels are provided with a plurality of water vapour interfaces 8, and processing kilns at different levels are communicated with hydrogen chloride gas recovery system 7 through pipeline.Though adopted rotary kiln in the prior art, many employing high-temperature roastings, the utility model has adopted the scheme that 5-10 water vapour interface 8 is set at every grade of processing kiln at 800-900 ℃ thereby temperature of reaction is many, and concrete reaction formula is following:
2FeCl
3?+?3H
2O?→?Fe
2O
3?+?6HCl↑
4FeCl
2?+?O
2?+?4H
2O?→?2Fe
2O
3?+?8HCl↑
Structure thus; Through enough water vapour being provided to the intravital material of high temperature kiln, make muriate and water vapour that above-mentioned chemical reaction at high temperature take place, generate hydrogen chloride gas; Again through hydrogen chloride gas recovery system 7 separating hydrogen chloride gases; Thereby reach the purpose of removing cl ions, fundamentally avoided simple hyperthermia drying device can only remove acid washing iron red middle remaining hydrochloric acid, greatly improved the separation efficiency of cl ions; And the chloride ion content of finished product materials is merely 0.10%, has improved resource utilization.Reduced the temperature of reaction of entire equipment, the temperature of reaction of the utility model has reduced energy consumption effectively usually at 300-650 ℃.
