Background technology
Blast refers to because material abrupt oxidization or decomposition reaction generation temperature, pressure increase or both are simultaneously increased existing
As.Fuel gas, flammable liquid steam or dust mix with air reach certain proportion after, meet fire occur burning release heat,
And make heated combustion product, heating, volumetric expansion.It can occur if the combustion product of expanded by heating can not drain in time quick-fried
It is fried.According to statistics, blast is to cause serious personal's injures and deaths and property loss in fuel gas, flammable liquid and dust fire accident
One of an important factor for.To fuel gas, the dangerous Journal of Sex Research of flammable liquid or dust combustion blast can further improve people
Awareness of safety, for prevent and successfully dispose fuel gas, flammable liquid or dust combustion explosion accident have important meaning
Justice.Therefore, the class demonstration experiment is highly desirable, student is educated.
At present, the lecture experiment of blast is concentrated mainly in dust explosion demonstration in the lab, if but this experiment press
Step described in teaching material is closed in photograph and device is set, and experiment effect is unsatisfactory.It is mainly manifested in：First, reaction vessel uses metal
Material, it is difficult to it was observed that the combustion phenomena in container；If second, using glass container, although it is observed that container internal combustion decrepitate
Fried scene, but the potential safety hazard that glass explosion is hurted sb.'s feelings be present；Third, igniter can not control flame size, and easily it is blown into
Air-flow extinguishes；Fourth, it single can only realize that dust explosion is demonstrated.To solve the above problems, therefore design this utility model device.
The content of the invention
The purpose of this utility model precisely in order to the defects of overcoming above-mentioned prior art situation to exist, and one kind is provided can
Combustion gas body, flammable liquid and dust explosion demonstrating experiment device are integrated in one, and experimental implementation is easy, can clearly reflect combustible gas
The apparatus for demonstrating of body, flammable liquid steam or dust explosion experiment.
The purpose of this utility model is achieved by the following technical solution.
A kind of multi-functional explosion test apparatus for demonstrating, including polycarbonate plastic explosive container and it is located at polycarbonate plastic
The makrolon blast device cover plate on explosive container top, butane storage tank is connected with simultaneously in polycarbonate plastic explosive container inner bottom part
Controlled by butane atmosphere control valve, be provided with piezoelectrics in butane atmosphere control valve mouth, and set above piezoelectrics
There is Wind-proof flame blowtorch, be provided with explosive container by the fuel gas ingress pipe of outside access, exploded in polycarbonate plastic
Container inner bottom part is equipped with volatile flammable liquid holder；Wherein, butane storage tank and piezoelectrics connect with Wind-proof flame blowtorch
Connect, form ignition system；The external fuel gas of fuel gas ingress pipe；Starch funnel is arranged on polycarbonate plastic explosive container
Bottom, it is connected with drawing the drum air hose outside being connected to.
Required experimental article also has experimental drug：Fuel gas, volatile flammable liquid, butane, combustible dust.
The beneficial effects of the utility model are can to allow student in study fuel gas, flammable liquid and dust explosion
Knowledge is easily mastered during appearance, teacher is also easier to teach, and the teaching demonstration device shows that relatively more directly perceived, lively, understanding sense is strong, energy
It is enough effectively to unify rational knowledge with perceptual knowledge, and the efficiency of teaching to student can be effectively improved.
The beneficial effects of the utility model are that, as a result of above technical scheme, have significant technique effect：Collection can
Combustion gas body, flammable liquid and dust explosion demonstrating experiment device are integrated, and experimental provision is simple, easy to operate, and success rate is high, real
Test interesting, the origin cause of formation and the phenomenon of being exploded to student's visual understanding have preferable teaching demonstration effect.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Embodiment
See Fig. 1, a kind of multi-functional explosion test apparatus for demonstrating, including polycarbonate plastic explosive container 1 and be located at poly- carbon
The makrolon blast device cover plate 2 on the top of acid esters plastics explosive container 1, is connected in the inner bottom part of polycarbonate plastic explosive container 1
There is butane storage tank 3 and controlled by butane atmosphere control valve 4, piezoelectrics 6 are provided with 4 mouthfuls of butane atmosphere control valve, and
The top of piezoelectrics 6 is provided with Wind-proof flame blowtorch 5, is provided with explosive container 1 by the fuel gas ingress pipe of outside access
7, it is equipped with volatile flammable liquid holder 8 in the inner bottom part of polycarbonate plastic explosive container 1；Wherein, butane storage tank 3 and piezoelectricity
Igniter 6 is connected with Wind-proof flame blowtorch 5, forms ignition system；7 external fuel gas of fuel gas ingress pipe；Starch funnel 9
The bottom of polycarbonate plastic explosive container 1 is arranged on, is connected with drawing the drum air hose 10 outside being connected to.
The utility model is lighted a fire using butane as fuel by piezoelectrics, can use butane atmosphere regulating valve regulation fire
Flame size.The blast lecture experiment of fuel gas, volatile flammable liquid and dust can be carried out respectively.And it can be gathered by transparent
Carbonic ester explosive container observes whole explosion phenomenon.Whole experiment process is simple to operate, and controllability is strong, and success rate is high.
Operating procedure：
1. flammable gas explosion is tested：Makrolon is exploded into device cover plate lid on explosive container, opens external storage tank, will
Fuel gas is imported into explosive container by fuel gas ingress pipe.Butane atmosphere regulating valve is opened afterwards, passes through piezo-electric ignition
Device, light flame and trigger flammable gas explosion, explosion wave throws cover plate upwards.Combustion explosion can be observed by container
Phenomenon.
2. volatile flammable liquid explosion test：Volatile flammable liquid, lid are injected in volatile flammable liquid holder
Upper cover plate opens butane atmosphere regulating valve after the certain time that evaporates, and by piezoelectrics, it is flammable to light flame initiation
Gas burst, explosion wave throw cover plate upwards.Observation burning and explosion phenomenon.
3. dust explosion lecture experiment：A certain amount of combustible dust is added in dust funnel, covers cover plate, opens butane
Atmosphere regulating valve, by piezoelectrics, light flame.Air-flow is blown into container by drum air hose, is suspended in dust
In container, trigger dust combustion blast, explosion wave throws cover plate upwards.Observation burning and explosion phenomenon.
The several items that should be noted in experimentation：
1. during volatile flammable liquid explosion test, a period of time row igniting again is needed to wait for after adding liquid, so as to flammable
Liquid vaporses form flammable explosive with air.
2. dust explosion is tested, dust addition should not be excessive, in order to avoid air-flow is difficult to kick up in dust, influences experiment effect
Fruit.Meanwhile add dust and need to keep drying.
3. during experiment, observer should be observed by explosive container side, must not just be observed on the cover board, in order to avoid
Injury to personnel is caused when cover plate flies up.
