Separating type tunnel ventilation and dust removal system

The utility model aims to provide a separated tunnel ventilation and dust removal system. Comprising an air supply mechanism for inputting fresh air into a tunnel, a smoke exhaust mechanism for exhausting dust-containing gas, a movable dust removal mechanism for preparing magnetized active water and converting the magnetized active water into foam to be sprayed out, and a fixed dust removal mechanism for removing dust on the tunnel face in a close range; the multiple mechanisms are used in cooperation, ventilation in the tunnel is rapidly achieved, the dust concentration is reduced, the separation type tunnel ventilation and dust removal system can achieve ventilation, the air quality is greatly improved, meanwhile, the working environment of workers is improved, and smooth construction is facilitated. 本实用新型的目的在于提供一种分离式隧道通风除尘系统，包括给隧道输入新鲜空气的送风机构、用于将含尘气体排出的排烟机构、用于制备出磁化活性水以及将磁化活性水转化成泡沫喷出的移动除尘机构以及对掌子面近距离除尘的固定除尘机构；该多个机构互相配合使用，快速实现隧道内通风和降低粉尘浓度，该分离式隧道通风除尘系统不仅能够实现通风，而且大幅度的提高了空气质量，同时也改善了工人的作业环境，利于施工顺利进行。
