Dynamic high-pressure cooking rotary kiln for preparing alpha phosphogypsum and control method of dynamic high-pressure cooking rotary kiln
The invention relates to the technical field of ardealite treatment, and discloses a dynamic high-pressure cooking rotary kiln for preparing alpha ardealite and a control method of the dynamic high-pressure cooking rotary kiln. The dynamic high-pressure cooking rotary kiln comprises a feeding piece, a kiln assembly and a valve assembly. The kiln assembly comprises a feeding tank, a cooking kiln and a discharging tank; the feeding tank, the cooking kiln and the discharging tank are coaxially arranged along a rotation axis; a heating assembly is arranged on the peripheral wall of the cooking kiln; the valve assembly comprises a first control valve, a second control valve, a third control valve and a fourth control valve, the first control valve is arranged between the feeding piece and the feeding tank, the second control valve is arranged between the feeding tank and the cooking kiln, the third control valve is arranged between the cooking kiln and the discharging tank, and the fourth control valve is arranged at the discharging end of the discharging tank; phosphogypsum raw materials supplied by the feeding piece can be sequentially conveyed along the feeding tank, the cooking kiln and the discharging tank. According to the method, the ardealite raw material can be continuously subjected to high-pressure dynamic cooking, so that'over-cooking 'can be avoided in the cooking process, and the crystal transformation efficiency of the alpha ardealite is greatly improved.
本发明涉及磷石膏处理技术领域，公开了一种制备α磷石膏的动态高压蒸煮回转窑及其控制方法。该动态高压蒸煮回转窑包括给料件、窑炉组件和阀门组件；窑炉组件包括进料罐、蒸煮窑和出料罐；进料罐、蒸煮窑和出料罐沿回转轴线同轴设置；蒸煮窑的周壁设有加热组件；阀门组件包括第一控制阀、第二控制阀、第三控制阀和第四控制阀，第一控制阀设于给料件和进料罐之间，第二控制阀设于进料罐和蒸煮窑之间，第三控制阀设于蒸煮窑和出料罐之间，第四控制阀设于出料罐的出料端；给料件供给的磷石膏原料能够沿进料罐、蒸煮窑和出料罐顺次输送。本发明能够持续地对磷石膏原料进行高压动态蒸煮，可避免在蒸煮中出现“过蒸”，大幅度提升了α磷石膏的转晶效率。
