Abstract
The utility model discloses a kind of ground iron winds booth smoke evacuation analogue means, mainly solves the problems such as big cake injected volume, simulation wind booth smoke discharging effect difference.The device includes the wall of four sides square shape, with the bottom plate of wall connecting, the exhaust outlet being arranged at the top of wall, it is arranged on wall side bottom and air inlet in rounded shape, and the axial flow blower installed in air inlet, for being blown into air inlet, wherein, wall bottom outside is provided for installing the groove of axial flow blower, the cake combustion box of cake built in the setting of axial flow blower rearward end.By such scheme, the utility model has the advantages that simple in construction, cost is cheap, simulation wind booth smoke discharging effect is true, has very high practical value and promotional value in technical field of fire control.
Description
Technical field
Technical field of fire control is the utility model is related to, especially a kind of ground iron winds booth smoke evacuation analogue means.
Background technology
Wind booth is subway ventilation air-conditioning system part, is mainly used in subway station and running tunnel and carries out sky with extraneous
Gas exchanges.When fire occurs, it is necessary to which the dense smoke in subway station, running tunnel is arranged from air draft booth (or Piston Action Wind booth)
Go out.Ground iron winds booth smoke evacuation analogue means is discharged fume available for simulated fire operating mode leeward booth, can conveniently be examined by simulating the smoke evacuation of wind booth
The performance of the fire fighting device of wind booth installation site is surveyed, the exploitation and test for corresponding establishment equipment provide facility.At present, using straight
Connect launch cake burning simulated, its injected volume is larger, can not simulate a large amount of flue gases with certain speed from wind booth discharge when
Plume form, simulation effect it is poor.
Utility model content
The purpose of this utility model is to provide a kind of ground iron winds booth smoke evacuation analogue means, mainly solves to deposit in the prior art
The problems such as cake injected volume is big, simulation effect authenticity difference.
To achieve these goals, the technical solution adopted in the utility model is as follows：
A kind of ground iron winds booth smoke evacuation analogue means, includes the wall of four sides square shape, the bottom plate with wall connecting, is arranged on
Exhaust outlet at the top of wall, be arranged on wall side bottom and in round shape air inlet, and installed in air inlet, for
The axial flow blower of air-supply in air inlet, wherein, wall bottom outside is provided for installing the groove of axial flow blower, after axial flow blower
The cake combustion box of cake built in end set, by launching the cake of burning in cake combustion box, generate dense smoke, produced cigarette
Gas is delivered to by axial flow blower inside the wall of four sides square shape, is discharged by top exhaust outlet.
Optimally, low inside and high outside slope is set at recess outlet, and dense smoke is in upward flowing by slope.Axial flow blower
Air inlet is supporting to set 4 groups, and axial flow blower is separately positioned on the air inlet of four sides wall, and dense smoke blows from 4 directions of face
Enter, simulate truly iron winds booth smoke evacuation state.
Further, cake combustion box side wall with the fresh air inlet extraneous for connecting cake combustion box is respectively provided with bottom,
It is provided for launching the charging aperture of cake at the top of cake combustion box, ensures airflow smooth during axial flow blower work, cake combustion box
It is interior to be in negative pressure state, the fresh air inlet suction air of cake combustion box is arranged on to release negative pressure state, inside cake combustion box
Flue gas all inside the wall by axial flow blower to four sides square shape, flow of flue gas is unobstructed, reduces cake injected volume.By adding
Strong cake combustion box inner loop, ensure the sufficient oxygen of burning, cake burning is abundant, reduces cake injected volume.
Compared with prior art, the utility model has the advantages that：
The utility model surrounds the wind booth of simulation by four sides wall, and 4 groups of air inlets and axle are set in wall side bottom
Flow fan, the wind outlet of axial flow blower set a slope, and the trend risen is presented in the wind for making to blast, and simulates truly iron winds booth
Air draft；The cake smoke position of the device is arranged on the cake combustion box of the rearward end (i.e. axial flow blower import) of axial flow blower
Interior, axial flow blower, which works, be in negative pressure state in cake combustion box, fresh air inlet suction air, prevent dense smoke from charging aperture with
Air inlet is discharged；Flue gas caused by cake smoke inside cake combustion box is all delivered to four sides square shape by axial flow blower
Inside wall, flow of flue gas is unobstructed, makes cake burning abundant, reduces cake injected volume, reduce cost., should by such scheme
Device has the advantages that simple in construction, cost is cheap, simulation true effect, has very high practical value in technical field of fire control
And promotional value.
