The improvement of gas air supply system, safe and reliable Journal of Sex Research being devoted to raising system etc..Abroad with in the fire-fighting and rescue of domestic city
The large-scale mobile vehicle-mounted fire-fighting inflation equipment used, preferably solves on-the-spot supply problem.But it involves great expense, uses
High in cost of production shortcoming, is not particularly suited for equipment of small motor rescue and field performs task and air respiratorresuscitator is inflated actual demand.
Inventor finds that during realizing the present invention defect of prior art is:
When performing emergency management and rescue task, field condition proposes the highest requirement to air respiratorresuscitator inflation to charging efficiency, needs
Want air respiratorresuscitator each gas cylinder to substitute the bad for the good within a short period of time, air matter in multiple gas cylinder and gas cylinder can be filled within a period of time
Amount is preferably.And present case, compressed air charger is that the inflationtime of every gas cylinder (6.8L) is typically at about 8 minutes.
Heat can be produced in gas replenishment process, inflation gas cylinder is had an impact, and the apparatus overheat that works long hours, typically take continuous work
After making 1 hour, orderly closedown cools down 10-20 minute.These have impact on the efficiency of inflation.
For giving air respiratorresuscitator inflating gas cylinder efficiency high in satisfied on-the-spot a period of time in the wild, two need to be solved further and mainly ask
Topic: one is the shortest to each inflating gas cylinder time under ensureing safety and gas cylinder premise in service life.Two is in certain time

Solve the problem that air respiratorresuscitator each gas cylinder is substituted the bad for the good, can be filled multiple gas cylinder within a period of time within a short period of time.Invention one
Plant field fast aeration method and apparatus safely and efficiently.
Technical scheme:
(1) concrete resolving ideas
For problem one, how solving single air cylinder, to be full of the gases at high pressure time the shortest.Analyzing current practice is to utilize
Air compressor is inflated, and compresses atmospheric air step by step, and in making air respiratorresuscitator gas cylinder, air reaches 30MPa pressure, and
It is full of gas cylinder capacity.If it is T that its single air cylinder is full of the time of gas, atmosphere gas is compressed to the compression time of 30MPa gas
For T1, the filling time of the 30MPa gas filling full gas cylinder capacity is T2, i.e. T=T1+T2.Through experimentation, for
To under the constraints that single air cylinder inflationtime is the shortest, we use the method for isobaric convection current QI invigorating, will be equipped with 30MPa
The compressed air of pressure is directly filled to gas cylinder, omits the T1 time, reaches single air cylinder and is full of the gas time and only needs the filling time to be T2,
Accomplish that the time is the shortest.I.e. use the high-pressure gas cylinder group that capacity is big " can fill " directly to carbon fiber gas cylinder, be equivalent to inflation
Machine work ahead.
For problem two, how within a period of time, to fill multiple gas cylinder.Owing to during fast aeration, pressure change can make gas cylinder
Produce heat, for ensureing safety and gas cylinder service life, variations in temperature during our inflating gas cylinder to be controlled.Current long-time work
Making apparatus overheat, after typically taking to work continuously 1 hour, orderly closedown cools down 10-20 minute.We take to reduce and shut down cooling
Time, the extension device working time, inflate to multiple gas cylinders simultaneously simultaneously, really realize fast aeration.
As known from the above, the gas charging system that charging efficiency is high should be: huge discharge inflator+jumbo gas bomb group+inflator is not
The work being interrupted.
Through fast aeration process is carried out experimentation and numerical simulation, same due to the temperature effects in gas replenishment process during fast aeration
Time affect use temperature limiting and the inflation rate of gas cylinder, therefore how controlling temperature effects while shortening inflationtime just becomes
Improve charging efficiency and guarantee the key of gas cylinder safely.Although experiment shows that improving bleed pressure can increase inflation rate, but increases and add
Operating cost.Improving and have a cost analysis optimal value between inflation rate and increase source of the gas gas storage volume, this is required for specifically
Situation analysis.
Use during mass-changed system thermodynamics and aerodynamics theoretical research hermetic container fast aeration fluid in pipeline
Flowing law and hermetic container temperature changing regularity.If initial time, the gas parameter in container is p1, T1, m1.Open valve
Door, after the inflation t time, gas in container parameter is pt, Tt, mt.After gas charging system itself determines, temperature before and after inflation
Change relevant with pt/p1, unrelated with the size of container itself.This is because gas replenishment process can be interpreted as from physical essence
Former gas in a reservoir is carried out adiabatic compression, and mixes the synthesis result of the two process with insufflation gas mutually.Experiment table
Temperature in lucid and lively speed gas replenishment process significantly changes and mainly appears on the incipient stage, as long as illustrating to weaken the temperature effects of incipient stage
Just can control the temperature effects in whole gas replenishment process.
Concrete measure: one is the downward trend controlling inflation actual pressure ratio, though bleed pressure step variation, can be effective
Avoid the container temperature rise that caused by " pressure waste ", so that vessel temp is relatively without declining to a great extent in the case of control.Two is to pass through
Radiating and cooling.Use the method controlling each device temperature increasing degree for this, reduce and shut down cool time, the extension device working time,
Inflate to multiple gas cylinders simultaneously simultaneously, really realize fast aeration.
