Ventilation system for tunnel construction

Abstract

The invention discloses a ventilation system for tunnel construction, and relates to the field of ventilation equipment for tunnel construction, the ventilation system comprises a fan pipe and a flow guide pipe, and the outer side of the fan pipe is sleeved with a mounting bracket. According to the ventilation system for tunnel construction, airflow can be more evenly distributed, the problems of blind areas and uneven airflow can be solved, a drainage plate and a first flow guide plate can guide the airflow to flow into a filter hopper, meanwhile, the turbulent flow and vortex phenomena in the airflow are reduced, the stability of the airflow is improved, and the ventilation effect is improved. Water mist sprayed by the spraying head adsorbs dust and is collected through the flow guide groove, most of the dust is prevented from entering the long-distance flow guide pipe, follow-up cleaning is facilitated, the air quality in the tunnel is detected through the air quality sensor and the temperature and humidity sensor, the opening and closing angle of the protection plate is adjusted, the air inlet amount is adjusted, and energy consumption is reduced. And the activated carbon filter screen is detachable, so that the working efficiency and convenience of the ventilation system for tunnel construction are improved.
