Embodiment
For ease of it will be appreciated by those skilled in the art that the utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment:
As shown in Figure 1, a kind of verifying attachment for fire-fighting smoke control system validity, comprise inside be equipped with supporting be fuming oil aerosol producer, the oil of being fuming is the water miscible oil of being fuming of nontoxic pollution-free, the air intake opening of aerosol producer is connected with the high pressure gas device by the carrier gas input pipe, the gas outlet of aerosol producer is connected with smoke vessel, and the endpiece of the smoke vessel in the present embodiment is " L " shape structure, and room wall is provided with the smog test macro.Smog test macro in the present embodiment comprises pilot lamp bundle and video camera; Wherein, the pilot lamp bundle vertically is arranged on the room wall, be provided with video camera at pilot lamp bundle same room wall, the video camera image pickup scope is the fire fighting device of pilot lamp bundle and check, pilot lamp bundle in the present embodiment comprises 2 above LED lamps, the distance of adjacent LED lamp is 0.4 ~ 0.6 meter, and the distance of adjacent LED lamp is 0.5 meter during practical application.
High pressure gas device in the present embodiment is gas cylinder, and it is the safe gas such as nitrogen or carbon dioxide that the gas in the gas cylinder requires, and tensimeter is equipped with at the gate out switch place of gas cylinder.Aerosol producer comprises aerosol producer body and PID controller, and the PID controller is connected with the aerosol producer body.
A kind of implementation method of the verifying attachment for fire-fighting smoke control system validity may further comprise the steps:
(1), aerosol producer is positioned in the tested room;
(2), the air intake opening of aerosol producer is connected with the high pressure gas device by the carrier gas input pipe, the gas outlet of aerosol producer is connected with smoke vessel;
(3), the pilot lamp bundle in the smog test macro vertically is arranged on the room wall, is provided with video camera at pilot lamp bundle same room wall, opens pilot lamp bundle and video camera;
(4), the oil of will being fuming pours in the aerosol producer, presses the hot key that adds of aerosol producer;
(5), when heating-up temperature during near design temperature, press the release key of aerosol producer;
(6), the high pressure gas device opens, it is the smoke particle of micron level that the smog in the aerosol producer continues outwards to discharge diameter by smoke vessel;
(7), smoke particle is raised to rapidly the top in room, the ceiling jet of simulated fire smog then occurs, the forward of smoke particle begin to around spread, observe by video camera, when smog arrives pilot lamp bundle bottom, open smoke control system;
(8), observe by camera recordings and to pilot lamp Shu Jinhang, draw by analysis assay.
High pressure gas device in the described step (2) is gas cylinder, and the pilot lamp bundle in the step (3) comprises 2 above LED lamps, and the distance of adjacent LED lamp is 0.4 ~ 0.6 meter, and the design temperature in the step (5) is more than 350 degree.
When the design for fire protection in newly-built building need to be checked and accepted, with the middle part of the utility model Plant arrangement in large space, and according to field condition layout smog test macro.The flow process of check is: checking first smoke alarm, then is the interlock control of fire fighting device, checks at last fire resisting shutter, smoke control system.
Before the experiment beginning, whether the oil of being fuming of confirming aerosol producer is sufficient, whether the pressure of gas cylinder is enough large, after beginning heating, note the variation of temperature, when reaching design temperature, need slowly open gas cylinder, and adjust the release rate of smog according to the size in space, then whether the result by the smog test macro to draw smoke control system qualified.
As shown in Figure 2, verifying attachment of the present utility model begins to discharge smog, smog arrives ceiling, then observe smog decline process by video camera, and record the moment that smog drops to first LED lamp, smog drops to the moment of second LED lamp, in like manner, record smog always and drop to moment of end LED lamp, at this moment, open smoke control system, begin to observe the smog uphill process, and record smog rises to the moment of end LED lamp, in like manner, record smog always and rise to the moment of pushing up the LED lamp most, at this moment, close smoke control system, test ending.
On-the-spot shooting can find that the fire resisting shutter impermeability in corridor, the two, three building is good not, causes exit corridor that the cigarette of leakage situation is arranged.Can find by record form, as shown in Figure 2, opened smoke-discharging blower fan after smog discharges 450s, flue gas layer is after dropping to minimum 6m height, beginning is slowly risen, finally can be so that flue gas layer rise to the 9m height in 300s, and this can not affect personnel's safe escape highly substantially.Therefore reach a conclusion as the smoke evacuation system in this building is good (the amount of smoke of HRR＜4MW) produce that design power can the small-sized fire of timely and effective discharge.
Above-mentioned embodiment is preferred embodiment of the present utility model; can not limit the utility model; other any change that does not deviate from the technical solution of the utility model and make or other equivalent substitute mode are included within the protection domain of the present utility model.
