Abstract
The utility model discloses a fire hazard flue gas simulation timing quantitive control device, which can be used to control the production of the flue gas in the fire hazard flue gas simulation process during the test or the fire drill regularly and quantitively. The fire hazard flue gas simulation timing quantitive control device comprises a combustion chassis, a spiral type combustion chamber, a combustion control sheet and a flue gas concentration cover. The combustion chassis is a bottom plate. The spiral type combustion chamber and the combustion control sheet are disposed on the combustion bottom plate. The device has advantages of simple structure, wide application, and abilities of realizing quantitive and timing control of simulated flue gas and saving flue gas generating material.
Description
Technical field
The utility model relates to the fire safety evaluating technical field, is specially a kind ofly to can be used for testing or the device of the quantitatively timing controlled flue gas generation of fire smoke simulation during fire-fighting drill.
Background technology
Because the fire combustion position is very incomplete, all can produce a large amount of flue gases in nearly all fire.The temperature of fire smoke is higher and contain multiple poisonous, objectionable constituent, can personnel's safety and indoor article be constituted a serious threat.The existence of flue gas also can make the visibility in the buildings reduce.In space, the easy rapid spread of flue gas comes.
Carry out flue gas simulation at present, generally use " cake ", all fix but cake produces cigarette speed, smoke-producing amount, product cigarette time, can't quantitatively control after lighting.Particularly carry out correlation test, when research flow of flue gas rule, buildings or structures flue gas control scheme, need carry out meticulous control to the generation of flue gas.
Also have and heat the simulated fire flue gas after using other gases by mechanical mixture, this kind equipment is the generation of timing controlled flue gas quantitatively.But the flue gas the when flue gas that produces and real fire has certain difference, can not represent the flue gas of natural fire.And this kind equipment volume is bigger, also needs to connect power supply in addition and heats.
The utility model content
The technical matters that the utility model solves is to provide a kind of fire smoke to simulate control device at regular time and quantity, to solve the shortcoming in the above-mentioned background technology.
The technical matters that the utility model solves realizes by the following technical solutions:
A kind of fire smoke is simulated control device at regular time and quantity, comprise burning chassis, spiral firing chamber, burning control strip and fume centralized cover, described burning chassis is base plate, described spiral firing chamber and burning control strip all are arranged on the burning base plate, described spiral firing chamber is the helical space that spiral chamber wall surrounds, described burning control strip is placed in the spiral firing chamber, be the shape of falling T structure, described fume centralized cover cap is the low bamboo hat shape of middle high rim above spiral firing chamber.
The below of described fume centralized cover is provided with feet, and described feet can be stuck in outside the spiral firing chamber, supports the fume centralized cover, and plays the effect of location.
The centre of described fume centralized cover is circular smoke outlet, and the cigarette that produces in the spiral firing chamber is discharged by smoke outlet.
Vertical range maintains the slit the most nearby between the lower edge of described fume centralized cover and the spiral firing chamber, and the swabbing action of hot-fluid during burning can make fresh air entrainment in the firing chamber.
Slit between the lower edge of described fume centralized cover and the spiral firing chamber is about 1cm.
Described burning control strip is provided with altitude scale.
In the utility model, described burning chassis, spiral chamber wall and fume centralized cover all are the refractory steel plates structure.
Beneficial effect: the utility model can be by changing the time of the length control generation flue gas of placing smoker particles inside (powder) material, i.e. flue gas simulation timing controlled; Can be by changing the accumulation height of smoker particles inside (powder) material somewhere, the control somewhere produces amount and the speed of flue gas, i.e. quantitatively control of flue gas simulation; This apparatus structure is simple, and is scalable; Realize the quantitative and timing controlled of flue gas simulation, can save smoker particles inside (powder) material.
