Abstract
The utility model relates to a kind of tunnel multi-working face control ventilation device, the fan outside the import of auxiliary gallery generates wind and is sent to four ventilation pipes by first ventilation air duct;The wind at four ventilation pipes is sent to the working face at both ends of first positive hole by third ventilation air duct fixed in the top of first positive hole;The wind at four ventilation pipes is sent to three ventilation pipes fixed in the top of second intersection by second ventilation air duct fixed in the top of horizontal channel;The wind at three ventilation pipes is sent to the working face at both ends of second positive hole by fourth ventilation air duct fixed in the top of second positive hole, it can be realized by a fan Multiple working face ventilation, it needs less fan equipment and different working face ventilation route part general, so that the overall ventilation line is shortened, and then reduce cost.Can use controller to control the opening and closing degree of corresponding butterfly valve by relay, meet the demand of different process air supply of tunnel, can reduce energy consumption, improve economic efficiency.
