Ventilation control system for tunnel face

Abstract

The invention discloses a ventilation control system for a tunnel face. The ventilation control system comprises a control device, a tunnel ventilation device, an air quality status monitoring device, an oxygen generating plant and a liquid dust-removal spray device, wherein the control device is arranged on the tunnel face of a construction tunnel, the tunnel ventilation device is arranged in the construction tunnel, the air quality status monitoring device is used for monitoring the air quality status of the tunnel face of the construction tunnel in real time, and the oxygen generating plant and the liquid dust-removal spray device are distributed on the tunnel face of the construction tunnel. The tunnel ventilation device comprises multiple sets of air supply devices and an exhaust fan arranged on the tunnel face. The control device comprises a control keyboard, a monitor, a keyboard circuit, a data storage unit and a second wireless communication module, wherein the keyboard circuit is connected with the control keyboard, and the data storage unit and the second wireless communication module are connected with the monitor respectively. The oxygen generating plant, the liquid dust-removal spray device and the exhaust fan are all controlled by the monitor and are connected with the monitor respectively. The ventilation control system is reasonable in design, convenient to install and lay, easy and convenient to use and operate, good in use effect, and capable of optimally regulating and controlling environmental conditions of the tunnel face.

Description

technical field [0001] The invention relates to a control system, in particular to a ventilation control system for tunnel faces. Background technique [0002] The function of ventilation in tunnel construction is to deliver enough fresh air from the outside of the tunnel to the inside of the tunnel, and discharge the gun smoke and harmful gases produced by blasting and transportation in the tunnel, so as to finally ensure the needs of the workers and machinery in the tunnel for fresh air, so that the inside of the tunnel The air meets the standards stipulated by the country and the industry. The quality of the ventilation effect in the construction of long tunnels directly affects the progress of the project and the health of the workers. At present, the tunnel construction ventilation at home and abroad mostly adopts the pipeline press-in ventilation method, and an axial flow fan is installed outside the tunnel entrance. The dirty air in the tunnel will be discharged out...

AI Technical Summary

Problems solved by technology

Nowadays, after the ventilation equipment used in tunnel construction is laid out and the parameters are set, it is generally not adjusted accordingly. However, due to various emergencies in the actual construction process, the air quality at the tunnel face will be affected to varying degrees , and there will be differences in the working status of the ventilation equipment

In addition, dust and other particles in the air cannot be completely taken out of the tunnel with the dirty air. Therefore, it is difficult to optimally control the air quality at the face of the tunnel if it is close to the existing ventilation device.

To sum up, there is a lack of a tunnel face ventilation control system with reasonable design, convenient layout and installation, easy operation, high intelligence, and good use effect, which can monitor the results of the air conditions at the face, Corresponding optimal control of the environmental conditions at the face of the operation
