Abstract

本发明涉及矿井粉尘治理技术领域,具体公开了一种采煤转载点异质核化‑超重力协同粉尘净化装置。该装置包括:异质核化‑超重力协同除尘装置、负压风机、离心机及沉淀式污水处理装置。其中,除尘装置由筒式一体化外壳体、多级填料组件和循环式水冷壁组成。工作时,负压风机将含尘气体吸入,水冷壁维持装置内部低温环境,诱导粉尘发生异质核化效应;同时,离心机驱动多级填料高速旋转形成超重力场,对含尘液滴进行高效捕集与分离。洁净气体经顶部排出,含尘污水则流入沉淀式污水处理装置。本发明通过异质核化与超重力的协同作用,显著提升了对采煤转载点全粒径粉尘的捕集效率(可达95%以上),同时具有用水成本低、结构紧凑、对井下空间适应性强的优点。
