Abstract
The utility model discloses a test device for the plume short circuit, including tuber pipe, outdoor exhaust port, outdoor air inlet and fan. The device can effectively avoid plume short circuit phenomenon through the experimental position relation who obtains a reasonable outdoor exhaust port and each across block overall arrangement of air intake.
Description
Technical field
The utility model relates to buildings affiliated facility, is specifically related to a kind of test unit of plume short circuit.
Background technology
After building fire occurs, the heat smoke that outdoor exhaust opening is discharged can be caused the effect of similar " short circuit " by the mechanic pressure blow system and the outdoor air inlet suction of smoke evacuation air-makeup system, very large impact will be caused on smoke exhaust efficiency, even can jeopardize the life security of Evacuation.
Specify according in " Code for fire protection design of buildings " GB50016-2006 of China: " the outdoor air inlet of 9.4.7 mechanism contact type sensor fume-resisting system and smoke evacuation air-makeup system should be arranged in the below of outdoor exhaust opening, and the discrepancy in elevation should not be less than 3.0m; When horizontally disposed, horizontal range should not be less than 1 () .0m." in addition, specify in " metro design code " GB5007-2003 of China: " and 12.2.43 when entering, air draft booth is when building jointly, exhaust outlet should exceed 5m than air inlet, or direction of staggering, air port is arranged, and enter, exhaust outlet minimum spacing should be greater than 5m.”
After building fire occurs, cause plume short circuit phenomenon, outdoor exhaust opening should be consistent with above-mentioned relevant specification of country with the layout of outdoor air inlet.But in fact, in order to increase outdoor buildings exhaust opening exhaust smoke level, also increase outdoor air inlet intake, a lot of outdoor buildings often arranges more than 1 group of exhaust opening and air inlet simultaneously, to reach the object of smoke evacuation and air intake fast.If each group exhaust opening and air inlet layout unreasonable, although often meet the requirement of relevant specification of country between group, but outdoor buildings limited space after all, very easily cause the plume short circuit phenomenon of exhaust opening and air inlet between each group, thus affect smoke exhaust efficiency, even can jeopardize the life security of Evacuation.
Summary of the invention
The plume short circuit that the position relationship respectively organizing a layout in view of above-mentioned outdoor buildings exhaust opening and air inlet causes, fire smoke is caused to be sucked by outdoor air inlet, thus reduction smoke exhaust efficiency, even jeopardize the situation of Evacuation life security, the utility model provides a kind of test unit for plume short circuit, to obtain the position relationship that a kind of rational outdoor exhaust opening and air inlet respectively organize a layout, avoid causing plume short circuit phenomenon.
In order to realize foregoing invention object, can implement by the following technical programs.
The utility model provides a kind of test unit of plume short circuit, it is characterized in that, a kind of plume short-circuit test device, it is characterized in that, this device comprises airduct 101,102,103,104, outdoor exhaust opening 201,202,203, outdoor air inlet 204,205, blower fan 301,302; Wherein said airduct 101 is smoke exhaust pipe, it is drawn and the 15m that stretches out by blower fan 301, airduct 101 holds up airduct 103,104 and outdoor exhaust opening 201 respectively at interval of 5m, the height of described airduct 103 is 5m, the height of 104 is 3m, airduct 103 is arranged outdoor exhaust opening 203, airduct 104 is arranged outdoor exhaust opening 202; Airduct 102 is tonifying Qi airduct, and it is drawn and the 10m that stretches out by blower fan 302, described airduct 102 is arranged respectively the outdoor air inlet 204,205 that level interval is 5m, and air inlet 204,205 is highly 0m.
Wherein said outdoor exhaust opening 201,202,203, outdoor air inlet 204,205 is preferably made by the window shutter of four sides opening.
The blinds of wherein said window shutter preferably downwards in angle of 45 degrees.
Bottom wherein said airduct 103,104, preferably 0.5m place arranges opening 401,402 respectively from bottom to top, and bottom outdoor exhaust opening 201,0m place arranges opening 403 from bottom to top.
Bottom wherein said air inlet 205, preferably 0m place arranges opening 501 from bottom to top, and bottom air inlet 204,0m place arranges opening 502 from bottom to top.
Orderly that of wherein said opening 401,402,403,501,502 inserts iron plate 601 by testing requirements.
Adopt the plume short-circuit test device that technique scheme makes, can obtain by test the position relationship that a kind of rational outdoor exhaust opening and air inlet respectively organize a layout, effectively avoid plume short circuit phenomenon.
