description | The utility model belongs to a ventilation technology of tunnel and underground projects and provides a plateau tunnel ventilation air-preheating device. The device essentially consists of a ventilating pipe (1), a ventilator (2), an air tube (3), a heater unit (4) and a heat supply recycling mechanism; wherein, a plurality of parallel heater units (4) are connected with the tunnel ventilator through the air tube (3); the heat supply recycling mechanism mainly includes a steam boiler (5), a steam pipe (7) and a condensed water box (8); the steam pipe (7) enters the heater unit. The water returning pipe of the steam boiler (5) is provided with a condensed water box (8) that is communicated with the steam pipe in the heat unit through pipes. The device of the utility model has the advantages of simple structure and easy installation. The heat source adopts the steam boiler at the construction site, so the effect is obvious in tunnel construction of plateau cold areas. |
