Description
Technical field
The present invention relates to the fields such as teaching experiment, safety engineering, fire-proof and explosion-proof engineering, are imparted knowledge to students more particularly to back-fire relief explosion arrestment
Test and put into practice field.
Background technology
At present, fire prevention and anti-explosion engineering are an essential teaching and practice in Safety Engineering Major curricular system
The course being combined, specialized compulsory class is all established as in the school for largely offering Safety Engineering Major.At present, due to fire prevention
The popularization of explosion-proof technology is not high, and considerably less suitable for the experimental rig of Safety Engineering Major practical teaching.This secondary design with
The back-fire relief explosion arrestment experimental system of exploitation, belongs to fire-proof and explosion-proof technical field, is examined in combination with Safety Ergonomics, safety devices
Survey.It is intended to the design concept being combined by interactive and security, using prevent fires with the rudimentary knowledge of anti-explosion engineering course as
Basis, it is the practice service of this course, can act also as the Specialty Experiment or comprehensive real in Safety Engineering Major practice
Test use.In industrial processes, because of the tunnel-effect of pipeline, flame or explosion wave in turn result in accident along pipe transmmision
The accident expanded again is a lot, explosion arrestment explosion suppression device can effectively prevent its propagation, but detects explosion arrestment without a set of ripe system
The functional effect of the devices such as datonation-inhibition, explosion arrestment explosion arrestment.
The content of the invention
It is an object of the invention to provide a kind of back-fire relief explosion arrestment experimental system, is burnt by combustible vapor or gas, and shape
Into after blast or detonation, visually intuitively understand flame and produce, propagate, developing and pass through, and the effect of back-fire relief device of blast prevention
Effect, by processing systems such as pressure, temperature signals, with reference to the basic theories of fire-proof and explosion-proof technology, fired by steam or gas
The tracing analysis of detonation pressure power, temperature development process, judge back-fire relief explosion arrestment effect of the back-fire relief device of blast prevention in terms of gas burst.
The technical solution for realizing the object of the invention is：
Back-fire relief explosion arrestment experimental system, including 1 gas cylinder, 2 igniters, 3 detector tubes, 4 pressure gauges, 5 temperature sensors, 6 pressure
Sensor, 7 back-fire relief devices of blast prevention, 8 pressure release tanks, 9 safety valves, 10 power control systems, 11 data collecting systems, 12 vavuum pumps.
The present invention compared with prior art, its remarkable advantage：
1st, system has the observing function of flammable liquid steam or flame of combustible gases along pipe transmmision, other back-fire relief explosion arrestments
Class experimental system does not possess.
2nd, system has the quantitative detection function of the safety means facilities such as temperature sensing, explosion wave pressure detection simultaneously,
Other experimental systems can not be provided simultaneously with.
3rd, system has the experimental data detection function that flame and blast impulse are blocked, and other systems can not accomplish explosion arrestment
Experiential function.
4th, whole system be provided with each unclosed valve close and interlock that ignition system can not start, and have safety relief
Device, other experimental systems do not possess.
5th, system uses Automatic Control pattern, can replace personnel manually operated completely, safety height.
The present invention is described in further detail below in conjunction with the accompanying drawings.
Brief description of the drawings
Fig. 1 is the structural representation of back-fire relief explosion arrestment experimental system of the present invention.

With reference to Fig. 1：
Embodiment 1：
Back-fire relief explosion arrestment experimental system, experimental system is extracted by necessarily required vacuum by vacuum system, by flammable gas cylinder
In fuel gas ratio as requested be filled with visual pipeline.Under the premise of the closing of all valves, setting is used
Sparking mode is lighted a fire, and is burnt the fuel gas in system and is formed blast or detonation, visually straight at detector tube
See and understand flame generation, propagate, develop and pass through.When flame and shock wave are after back-fire relief device of blast prevention, its fray-out of flame, impact
Ripple reduces.By to signal processing systems such as pressure, temperature, with reference to the basic theories of fire-proof and explosion-proof technology, then passing through to firing
The tracing analysis of the parameters advances process such as pressure, temperature, judge flame of the back-fire relief device of blast prevention in terms of fire and blast and quick-fried
Fried forming process, and the mitigation effect of back-fire relief device of blast prevention, and then allow operating personnel or experimenter to understand its safe work
The knowledge of the teaching fields such as journey, fire-proof and explosion-proof engineering, a step of going forward side by side card institute theory.
