The purpose of this utility model is to provide a kind of tunnel of high-efficient ventilation, rational in infrastructure, and ventilation effect is good, particularly long tunnel, can fast and efficiently by the air displacement in tunnel.
In order to achieve the above object, the utility model adopts following technical scheme: a kind of tunnel of high-efficient ventilation, comprise the tunnel that is open to traffic, the both sides in the described tunnel that is open to traffic be provided be oppositely arranged and the air intake passage separated by partition wall and the described tunnel that is open to traffic and air exhaust passage, described air intake passage is communicated with the described tunnel that is open to traffic through described partition wall by air intake arm, entrance first extractor fan of described air intake arm, described air intake passage is provided with the air intake house steward communicated with the external world; Described air exhaust passage was communicated by the air exhaust branch pipe be arranged on described partition wall with described being open to traffic between tunnel, and exit second extractor fan of described air exhaust branch pipe, described air exhaust passage is provided with the air draft house steward communicated with the external world.
As preferably, the difference between the height of described air intake passage and described air exhaust passage for described in be open to traffic the 1/4-1/3 of tunnel height.
As preferably, the position of the bottom, tunnel that is open to traffic described in described air exhaust branch pipe leads to.
As preferably, described air intake house steward is connected with the first blower fan sucked by outside air machinery in described air intake passage.
As preferably, described air draft house steward is connected with second blower fan of to be discharged by outside air machinery in described air exhaust passage.
As preferably, described air exhaust branch pipe comprise extend to described partition wall be positioned at described in the extension that is open to traffic on the metope in tunnel, described extension has the air inlet port be open to traffic in tunnel described in some alignings.
As preferably, described air intake arm and air exhaust branch pipe are evenly distributed on the middle part of described partition wall.
As preferably, be open to traffic described in described air exhaust branch pipe the distance entrance in tunnel or the minimum range of outlet are 3-5 rice.
As preferably, the entrance in tunnel or the minimum range of outlet of being open to traffic described in described air intake arm distance for described in be open to traffic the 1/5-1/4 of tunnel overall length.
By implementing technique scheme, the utility model has following beneficial effect: the utility model 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 the utility model one embodiment.
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.
