Technical Field
The utility model relates to a dust collecting equipment, in particular to dust collecting equipment who is used for reducing dust and harmful gas in the tunnel in tunnel tunnelling construction.
Background
In the current tunnel construction, the trackless transportation drilling and blasting method has become a main method for tunnel construction due to the characteristics of flexibility, rapidness and high efficiency. However, the trackless transportation drilling and blasting method can generate a large amount of free silica dust in the tunnel, and tail gas generated by fuel oil of various construction machinery equipment is mixed in the free silica dust, so that great harm is caused to physical and psychological health of tunnel construction personnel. The ventilation ash discharge in the existing tunnel construction basically depends on a fan to convey fresh air into a hole, and dirty gas such as dust in the hole is discharged out of the hole through an exhaust passage of the tunnel through pressure difference. Because the tunnel is a relatively closed space, the concentration of dust and harmful gases in the tunnel is very high, and the method cannot effectively reduce the concentration of dust in the tunnel, and particularly has an unobvious effect on the reduction of the concentration of the harmful gases.
