Abstract
The invention belongs to the field of municipal construction and relates to an efficient-ventilating tunnel which comprises an open traffic tunnel. An air inlet channel and an air discharging channel which are arranged oppositely and are separated from the open traffic tunnel through a partitioning wall are arranged on the two sides of the open traffic tunnel. The air inlet channel penetrates through the partitioning wall through an air inlet branch pipe and is communicated with the open traffic tunnel. A first air pumping device is arranged at an inlet of the air inlet branch pipe. The air inlet channel is provided with an air inlet header pipe communicated with the outside. The air discharging channel and the open traffic tunnel are communicated through an air discharging branch pipe arranged on the partitioning wall. A second air pumping device is arranged at an outlet of the air discharging branch pipe. An air discharging header pipe communicated with the outside is arranged on the air discharging channel. The efficient-ventilating tunnel is reasonable in structure, vehicle exhaust in the tunnel can be discharged into the ventilating channel quickly and efficiently and then can be discharged out, meanwhile, fresh air outside the tunnel is sucked into the tunnel, ventilating effect is good, and obvious effect is achieved especially on a long tunnel with a plurality of vehicles.

By implementing technique scheme, the present invention has following beneficial effect: the present invention is rational in infrastructure, fast and efficiently the vehicle exhaust in tunnel can be entered air exhaust passage, then discharge; Sucked in tunnel by fresh air outside tunnel, ventilation effect is good simultaneously, particularly for the long tunnel that vehicle is many, and more remarkable effect.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of one embodiment of the invention.
Detailed description of the invention
The tunnel of a kind of high-efficient ventilation as shown in Figure 1, comprise the tunnel 10 that is open to traffic, be open to traffic the both sides in tunnel 10 be provided be oppositely arranged and the air intake passage 20 separated by partition wall 101 and the tunnel 10 that is open to traffic and air exhaust passage 30, difference between the height of air intake passage 20 and air exhaust passage 30 is tunnel 10 1/4-1/3 highly that is open to traffic, this arranges and can ensure that waste gas is discharged, fresh air can at tunnel Inner eycle after sucking, and the present embodiment is 1/4.Air intake passage 20 is communicated with the tunnel 10 that is open to traffic through partition wall 101 by air intake arm 40, entrance first extractor fan 401 of air intake arm 40, air intake passage 20 is provided with the air intake house steward 50 communicated with the external world, and air intake house steward 50 is connected with the first blower fan 501 in outside air machinery suction air intake passage 20.Air exhaust passage 30 is communicated by the air exhaust branch pipe 60 be arranged on partition wall 101 with being open to traffic between tunnel 10, air exhaust branch pipe 60 comprises and extends to partition wall 101 and be positioned at the extension 602 be open to traffic on the metope in tunnel 10, extension 602 has the air inlet port that some alignings are open to traffic in tunnel 10, the number of air inlet port is depending on the length in tunnel, and usual one meter arranges one; Exit second extractor fan 601 of air exhaust branch pipe 60, air exhaust passage 30 is provided with the air draft house steward 70 communicated with the external world, and air draft house steward 70 is connected with the second blower fan 701 in outside air machinery discharge air exhaust passage 30.Because tail gas is in below usually, therefore air exhaust branch pipe 60 leads to the position of the bottom, tunnel 10 that is open to traffic.The air in tunnel portal or exit, can with the air free exchange in the external world, so air intake arm 40 and air exhaust branch pipe 60 are evenly distributed on the middle part of partition wall 101, the be open to traffic entrance in tunnel 10 or the minimum range of outlet of usual air exhaust branch pipe 60 distance is 3-5 rice, entrance or exit are in the 3-5 rice in tunnel, air energy free exchange, need by external force; The be open to traffic entrance in tunnel 10 or the minimum range of outlet of air intake arm 40 distance is the 1/5-1/4 of tunnel 10 overall length of being open to traffic, and the present embodiment is 1/5.
