针对皮江法炼镁生产过程中白云石煅烧工艺的不同,论述了3种白云石煅烧炉(回转窑、竖窑和流态化煅烧炉)的优缺点、国内外进展概况和应用现状。回转窑是目前煅烧白云石最为普遍的一种炉窑;竖窑用于煅烧白云石,已成为一种逐渐被淘汰的炉窑;流态化煅烧炉是一种新兴的白云石煅烧炉窑,有着很大的发展前景。基于流态化煅烧炉的优缺点,还提出了一种新型旋流煅烧炉的设想。最后对各种炉窑的优缺点进行了总结。 In view of the difference of dolomite calcination process in pidgeon process magnesium production, the advantages and disadvantages of three kinds of dolomite calciner (rotary kiln, shaft kiln and fluidized calciner), the progress and application status at home and abroad are discussed. Rotary kiln is currently the most common calcined dolomite a kiln; shaft kiln used to calcine dolomite, has become a gradually eliminated furnace; fluidized calciner is a new dolomite calciner kiln, Has a great development prospects. Based on the advantages and disadvantages of fluidized calciners, a new concept of a cyclone calciner is also proposed. Finally, the advantages and disadvantages of various furnaces were summarized.
