Advantage of the present invention is, prevents that main tunnel flue gas from getting into the safe escape passage, and the Smoke prevention effect is remarkable, and the flue excellent performance is simple in structure, can guarantee in the whole safe escape passage smokeless.
Description of drawings
Fig. 1 is a Smoke prevention structural representation in tunnel of the present invention.
The specific embodiment
Through embodiment characteristic of the present invention and other correlated characteristic are done further explain below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
As shown in Figure 1, mark 1-8 is respectively among the figure: bidirectional movement blower fan 1, air-supply bar seam 2, conversion air-valve 3, service channel 4, tunnel 5, safe escape passage 6, tunnel 7, service channel 8.
Embodiment:
As shown in Figure 1; Smoke prevention structure in present embodiment tunnel reaches two tunnels that laterally arrange 5 and tunnel 7, is provided with safe escape passage 6 therebetween; Between tunnel 5 and safe escape passage 6, be provided with service channel 8, between tunnel 7 and safe escape passage 6, be provided with service channel 4.
Bidirectional movement blower fan 1 malleation air outlet is respectively through four air-supply bar seams 2 that turn to air-valve 3 to connect four air curtains of control; Two groups of air-supply bar seams 2 that interface is provided with between secure tunnel fire escape 6 and tunnel 5; Wherein one group of air-supply bar seam 2 is positioned at the interface of tunnel 5 and service channel 8, and another group air-supply bar seam 2 is positioned at service channel 8 and safe escape passage 6 interfaces.Two groups of air-supply bars seams 2 that interface is provided with between secure tunnel fire escape 6 and tunnel 7, wherein one group of air-supply bar seam 2 is positioned at the interface of tunnel 7 and service channel 4, and another group air-supply bar seam 2 is positioned at service channel 4 and safe escape passage 6 interfaces.The deflection angle deflection flue gas of above-mentioned air-supply bar seam 2 pours in direction, and the angle of deflection is an optimum with 10 °-20 ° usually.
The negative pressure air intake of bidirectional movement blower fan 1 is communicated with tunnel 5 and tunnel 7 respectively.
The present embodiment method of operation is following:
