Description
Technical field
The utility model relates to the smoke evacuation system of station layer public area in the subway station, is specifically related to a kind of shield door standard metro station tunnel heat extraction platform public area smoke evacuation system of holding concurrently.
Background technology
The smoke evacuation scheme that extensively adopt the station layer public area in the at present domestic subway station that is provided with shield door is: utilize the smoke extractor exhaust fan that is arranged at the station station hall layer to discharge fume by time exhaust duct of station layer public area air-conditioning system, the smoke evacuation system that is the station layer public area is provided with separately, and separates between the smoke evacuation system in the station tunnel.Because the smoke evacuation air quantity of station layer public area is bigger, in order to satisfy the smoke evacuation requirement of station layer, need to increase back the size of exhaust duct, the headroom to building has considerable influence like this; Because need to increase the air quantity and the total head of smoke extractor exhaust fan, cause construction costs to increase to some extent again; And the setting separately respectively of the smoke evacuation system in the smoke evacuation system of station layer public area and the station tunnel, increased manufacturing cost and operation.
Summary of the invention
The purpose of this utility model is exactly in order to solve the deficiency that the above-mentioned background technology exists, to provide a kind of simple in structure, and cost is low, implements the platform public area smoke evacuation system of holding concurrently of shield door standard metro station tunnel heat extraction easily.
The technical solution adopted in the utility model is: a kind of shield door standard metro station tunnel heat extraction platform public area smoke evacuation system of holding concurrently, the station tunnel and the heat extraction air channel that is arranged on two ends, station layer public area that comprise the station platform both sides, the station tunnel two ends all are connected with the heat extraction blower fan, the station tunnel top is provided with tread heat extraction air channel, described heat extraction blower fan links to each other with tread heat extraction air channel by the heat extraction air channel, the bottom in tread heat extraction air channel is provided with first Electric air valve that is communicated with station tunnel, and tread heat extraction air channel is provided with second Electric air valve that is communicated with the platform public area near the sidewall of platform public area.
Further, the entrance point of described heat extraction blower fan and the port of export are provided with sound absorber.
Further, the entrance point of described heat extraction blower fan also is provided with the 3rd Electric air valve.
The utility model is by opening or close the Electric air valve that bottom, tread heat extraction air channel or sidewall are installed, and realizes heat extraction or smoke evacuation to capable district of rail, shield door standard subway station or station layer public area through the heat extraction blower fan of station station hall layer.Compared with prior art, the utility model combines the station layer public area with smoke evacuation system in the station tunnel, designs a kind of station tunnel heat extraction platform smoke evacuation system of holding concurrently, and effectively reduces the influence of airduct to the building headroom, has saved construction costs; And the air quantity of energy capable district of flexible modulation rail or platform public area, help the energy-saving run and the control and regulation of system.Have simple in structurely, cost is low, and it is convenient to implement, and control and regulation are simple, the advantage that operating cost is low.
