Specific embodiment
The utility model is further described in conjunction with attached drawing.
Embodiment 1:
A kind of market fire-fighting smoke evacuation system, as shown in Fig. 1, including 1 He of Vertical Channel being arranged in market side wall 101
The interconnection 2 for being arranged in market crown wall 102 and communicating with the Vertical Channel 1, the interconnection 2 include smoke path
21 and the separate cavities 22 between the smoke path 21 and market crown wall 102, smog in market is through Vertical Channel 1, horizontal
It is discharged to the smoke path 21 in channel, it,, can be right when especially passing through smoke path by channel since the temperature of smog is higher
The floor on market upper layer causes high temperature to damage, therefore separate cavities 22 are arranged, and reduces the loss of high temperature bring.Setting in smoke path 21
There is thermal insulation layer (not shown), the thermal insulation layer that thermal insulation layer can be made using existing any temperature insulating material guarantees logical
The integrality in road, it is ensured that it can be worked normally.It is provided with ventilating duct 23 in the separate cavities 22, can be injected into market fresh
Air is that the trapped person of the inside supplies oxygen.The smoke path 21 is communicated with the Vertical Channel 1, and the smoke path 21 is set
The outlet flue 211 being equipped with outside to market, the Vertical Channel 1 are provided with the smoke inlet 11 in opposite market.
Embodiment 2:
As shown in Figure 1 and Figure 2, a kind of market fire-fighting smoke evacuation system, including the Vertical Channel 1 being arranged in market side wall 101
With the interconnection 2 for being arranged in market crown wall 102 and communicating with the Vertical Channel 1, Vertical Channel 1 includes that smoke inlet 11 exists
