Single-end roadway series ventilation system and ventilation method

Abstract

The invention discloses a blind roadway series connection ventilation system which comprises air inlet assemblies and air return assemblies arranged in all blind roadways connected in series and an isolation fan cover arranged in a connection roadway, and the isolation fan cover is connected with all the air return assemblies. A monitoring device and an air direction adjusting device are arranged at the position, close to the isolation fan cover, of the air return assembly, and air flow in the air return assembly can be adjusted to be blown to the connection roadway or the isolation fan cover. According to the invention, the dirty air isolation fan cover is arranged to isolate dirty air and fresh air generated by each section of one-headed roadway, so that the dirty air is prevented from entering the working surface of the next roadway; the air quality pollution caused by multi-section series ventilation is avoided, the air quality of a subsequent roadway is ensured, and the overall ventilation efficiency is improved; a monitoring device is arranged to monitor the air quality of each section of roadway, a baffle is opened when the ventilation requirement is met, air flow is guided into the roadway, and a relay fan in a dirty air isolation fan cover is shut down; unnecessary energy consumption is reduced, and the energy-saving effect of the system is improved.
