Compared with the traditional six-sided fire whirl experimental apparatus, the six-sided fire whirl experimental apparatus has the advantages that wind inlet change conditions in fire scenes are simulated by means of adjusting opening modes and widths of the movable tempered glass doors, so that the experimental diversity can be improved, the research range can be enlarged, and fire whirl formation conditions and laws under the conditions of different wind inlet modes and widths can be researched.
Description
Technical field
The invention belongs to fire safety evaluating technical field, particularly a kind of can be at a kind of experimental provision of different air intake patterns and width Imitating fire whirl.
Background technology
Forset and glassland fire, in low intensive plan burn and when some urban architecture fire occur; usually there will be a kind of strong convection fire phenomena that shows as swirl flame; when the intensity of swirl flame is enough large; the mode of motion meeting flip-flop of its flame, forms the fire whirl with strong rotating forward movement.Air inlet width and patterns different in the scene of a fire can form dissimilar air flow field, this can cause nature to entrainment air velocity variation, successively inwardly velocity of propagation is different for rotational flow field, the complexity that forms fire whirl is different, fire whirl combustion intensity, temperature of combustion, rotational speed and flame height are different, and the HRR of fire is also not quite similar.The fire whirl duration and degree of heating and the direction of heat flow that form can be undergone mutation simultaneously, be difficult to prediction, this is by put out a fire to save life and property personnel's safety of serious threat, and fire whirl carries a large amount of burning bits pieces and spreads to flame range farther place in addition, form new burning things which may cause a fire disaster, this will make scene of a fire situation out of hand, cause more casualties and property loss.From six the seventies, people just have research to fire whirl, in fire whirl inducement mechanism, the aspect such as experimental simulation and numerical simulation has obtained certain achievement, wherein the research and development of experimental simulation device focus on how to form and shear flow field, and improve the aspects such as shear flow field stability, for example, Zhang Linhe (generation of fire whirl and rotation regulation research in vertical-shaped conduit model, Fire Science) etc. designed a hexagonal fire whirl generating means, this device is an enclosing wall type hexagonal prism, at six edge Central Symmetries, have 6 gaps that width is identical, and be provided with fair water fin.This generating means opening pattern is certain, and the experimental study of fire whirl under a kind of A/F can only be provided, and assay format is single, and range of application is little.The mechanism forming for fire whirl under different air intake patterns and width in the scene of a fire both at home and abroad at present, architectural feature changes, and the research that characteristic parameter changes is very few, does not find the report of the proprietary experimental provision of relevant this respect in existing technical information.
Summary of the invention
The object of the present invention is to provide a kind of can be at the experimental provision of different air intake patterns and width Imitating fire whirl.
Realize the technical solution of the object of the invention: a kind of six flank fire vortex experimental facilities, comprise orthohexagonal cylinder framework, be placed in the horizontal slip groove on CylGizmo top of the trellis and bottom outside limit, removable door made of tempered glass, exhaust fume collecting hood and fuel tank, removable door made of tempered glass and the supporting setting of orthohexagonal cylinder framework are also placed in horizontal slip groove, exhaust fume collecting hood is arranged at directly over cylinder framework, and fuel tank is built in cylinder framework bottom centre place.
The present invention has the following advantages: the removable door made of tempered glass of six fans is all fixed in the top of cylinder framework and the horizontal concrete chute on bottom outside limit, can freely adjust opening pattern and regulate A/F, and different opening patterns and A/F also can independent assortments, formation mechanism and the rule of research fire whirl under multiple condition, increase experiment diversity, expanded research range.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of six flank fire vortex experimental facility embodiment of the present invention.
Fig. 2 is the structural representation of removable door made of tempered glass lower limb pulley of the present invention and place chute.
Fig. 3 is the vertical view of experimental provision described in the embodiment of the present invention.
Embodiment
Referring to Fig. 1, the housing installing described in the present embodiment is orthohexagonal cylinder framework 1, this cylinder framework 1 is welded than the rectangle frame that is 3:1 by six length and width sizes, each rectangle frame is made by stainless-steel tube (in this example, stainless-steel tube cross section is the wide square structure of 2.5cm), cylinder framework 1 fixes on the ground, is the agent structure of fire vortex experimental facility; For fixing and mobile removable door made of tempered glass 2, in the top of cylinder framework 1 and the regular hexagon outer side edges of bottom, be provided with horizontal slip groove 4; In order to facilitate the observation of experimental phenomena, removable door made of tempered glass 2 is made by tempered glass, and removable door made of tempered glass 2 is supporting with cylinder framework 1 size; For safety be convenient to install pulley, at removable door made of tempered glass 2 surroundings parcel corrosion resistant plates; Each removable door made of tempered glass 2 side centre-height place is provided with handle, and several steel pulleys 3 are installed on its base and top margin, and removable door made of tempered glass 2 is arranged in the horizontal concrete chute 4 of cylinder framework 1, facilitates the movement of removable door made of tempered glass; Quantitative adjusting for the ease of experiment A/F is provided with scale, referring to Fig. 2 on horizontal concrete chute 4.Above cylinder framework 1, be provided with exhaust fume collecting hood 6, for fear of the flue gas speed not exclusively forming because of fuel combustion in fire whirl generating process, be greater than the exhaust rate of axial-flow type smoke exhaust fan 8, and cause flue gas in experimental provision to gather, affect the observation of experiment effect and experimental phenomena, the exhaust fume collecting hood 6 of this example is not connected with orthohexagonal cylinder framework 1, the air port area of exhaust fume collecting hood 6 is greater than the area of overlooking of orthohexagonal cylinder framework 1, the preferred 30:17 of its ratio, top at exhaust fume collecting hood 6 is provided with opening, be connected with smoke discharging pipe 7, through to outdoor, axial-flow type smoke exhaust fan 8 is embedded in smoke discharging pipe 7 inside.
As shown in Figure 3, in the situation that opening pattern is six symmetrical openings, regulate the A/F of removable door made of tempered glass 2, simulate formation condition and the rule of fire whirl under different air intake width.The uncovered fuel tank 5 that holds fuel, its specification has 5cm
