Round tower-shaped preprocessor

The invention discloses a round tower-shaped preprocessor which comprises a tower body, a mixing device is arranged in the tower body, a liquid distribution device is arranged on the tower body, and an atomization device is connected to the liquid distribution device. The conical liquid distribution device is additionally arranged on the round tower-shaped coal slurry preprocessor, and the dosing point and the liquid distribution feeding port are arranged in a centralized manner so that the problem of nonuniform linear feeding and dosing is effectively solved, the pretreatment precision is improved, and the purposes of low energy consumption and stable operation of a flotation production line are achieved. 本发明公开一种圆塔形预处理器，包括塔体，塔体流内设置有混合装置，塔体上设置有布液装置，布液装置上连接有雾化装置。本发明圆塔形煤浆预处理器的上方加装了锥形布液装置，并将加药点与布液入料口集中布置，有效解决了线性入料加药不均匀的问题，从而提高了预处理精度达到浮选生产线能耗低，运转平稳的目的。
