The invention discloses a novel mining ventilation multi-stage dust removal device and method, and relates to the technical field of mining dust removal equipment. The dust removal device comprises a dust removal box, and a dry dust removal mechanism, a wet dust removal mechanism and a cleaning mechanism are arranged on the dust removal box. The negative pressure fan is started through the controller, so that negative pressure is formed in the dust removal box, external contaminated air is sucked into the air inlet pipe, then primary dust removal can be conducted through cooperation of a coarse filter screen, a first dust collection box and other structures, and secondary dust removal is conducted under the action of a fine filter screen; dust attached to the surface of the fine filter screen can be cleaned through a telescopic rod, a cleaning block and other mechanisms, the dust falls into a second dust collection box, contaminated air enters the dust removal box after secondary dust removal, at the moment, water mist can be sprayed through a water tank guide pipe, a rotating rod, a spray head and other structures, and the dust removal effect is improved. And tiny dust in the air is adsorbed by the sprayed mist beads and falls onto the third-stage filter plate, so that third-stage dust removal is conveniently realized.

    本发明公开了一种新型矿用通风多级除尘装置及方法,涉及矿用除尘设备技术领域。本发明包括除尘箱,所述除尘箱上设置有干式除尘机构、湿式除尘机构和清理机构。本发明通过控制器启动负压风机,使得除尘箱内形成负压,将外部污浊空气吸入进风管内,然后通过粗效过滤网、第一集尘盒等结构的配合能够进行一级除尘,并在细效过滤网作用下进行二级除尘,且通过伸缩杆、清理块等机构还能够对细效过滤网表面附着的灰尘进行清理,使其落入第二集尘盒内,经过二级除尘后,污浊空气会进入除尘箱内部,此时通过水箱导管、转杆、喷头等结构,还能够喷洒水雾,使空气中的微小灰尘被喷出的雾珠吸附,并下落至三级过滤板上,便于实现三级除尘。
