Description
Technical field
The present invention is a kind of oxygen-supplying device in rail vehicle and method thereof that is used in the plateau operation, belongs to mechanical manufacturing field.
Background technology
Along with developing rapidly of urban track traffic, car body and the design of Che Nei facility structure are humanized.The guideway vehicle that is applied to the highlands operates in the abominable external environment condition, and interior oxygen concentration, temperature are all lower, even passenger in vigorous health often also altitude sickness can take place.Be the trouble and worry of travelling in releasing passenger plateau, and set up the emergency condition of tackling the passenger's body discomfort and bringing, common meeting be equipped with emergency oxygen apparatus on high plateau train.
Existing common apparatus of oxygen supply is the oxygen generating plant of single structure, just by the crew member this device is offered this passenger and use when a certain passenger needs oxygen uptake.If when oxygen is used up, then also need change this device, both increased passenger's intense strain, also make services loaded down with trivial details, wayward.
Summary of the invention
Oxygen-supplying device in rail vehicle of the present invention and method thereof, cause the lower present situation of whole oxygen concentration in the compartment at the highlands rarefaction of air, adopt the integral type oxygenerator and connect car body in-to-in air delivery duct respectively and form by the auxilliary distributing oxygen supply arm of establishing of staffing distribution situation in the compartment by supply air line.In the interior integrated environment, provide high-concentration oxygen, can introversive at one time all passengers provide the oxygen supply service.
The objective of the invention is to, realize the oxygen supply mode that a kind of disperse oxygen supply and distributing oxygen supply combine, prepared oxygen can solve whole passengers' oxygen uptake requirement in the integrated environment that balancedly is distributed in interior.
Goal of the invention also is, the mode that adopts supply air line to be connected with the air delivery duct of car body air-conditioning realizes the temperature of interior circulating air, the equilibrium adjusting of oxygen concentration, and more comfortable environment by bus is provided.
For realizing above-mentioned design goal, described oxygen-supplying device in rail vehicle, be that an all-in-one-piece oxygenerator is set in car body inside, the supply air line of this oxygenerator is connected to car body in-to-in air delivery duct and forms by the auxilliary distributing oxygen supply arm of establishing of staffing distribution situation in the compartment.
Adopt above-mentioned apparatus of oxygen supply, cross low and cause that passenger's body is not in good time when the oxygen concentration of interior, the oxygenerator supply air line is to car body in-to-in air delivery duct aerating oxygen.The on-cycle air-blending is to improve the content of oxygen in the air in the oxygen of input and the air delivery duct, and mixed air is transported to from the air delivery duct in the interior environment, promptly realizes disperse oxygen supply mode.
Also provide distributing oxygen supply when disperse oxygen supply mode is provided, promptly the supply air line of oxygenerator is formed by the distributing oxygen supply arm, directly exports high-concentration oxygen according to the distribution situation of seat in the compartment at passenger's seat place.
Further improvement project is that the supply air line of described oxygenerator is connected in the both sides of air delivery duct, car body top.
The oxygen that makes mixes with the on-cycle air in the air delivery duct and is delivered directly in the compartment, and the transport path of mixing air is correspondingly shorter, and the loss of oxygen is less.
More the organization plan of You Huaing also can be, the supply air line of described oxygenerator, and its terminal is connected in the air delivery duct of car body top interior environment system.
Because the temperature difference of highlands is bigger, normally interior environment system is installed at the top of guideway vehicle, the oxygen that oxygenerator makes is communicated in the air delivery duct of interior environment system, not only can improve the oxygen concentration of air-conditioning air-out, and can directly carry out thermal balance, keep the homogeneity of compartment air temperature.
The distributing oxygen supply arm of described connection supply air line is formed, and at each seat place one exhaust pipe mouth is set.Oxygen from exhaust pipe mouth output can more be evenly distributed in passenger's surrounding environment.
Be fixed with by interconnective Air compressor of pipeline and expansion tank in the car body bottom, the freeing pipe of expansion tank is connected in the air inlet pipe of oxygenerator bottom.
Import pressurized air with preparation oxygen with Air compressor to oxygenerator, because the air pressure of Air compressor output is higher, be the difference of pressure inside and outside the balance oxygenerator, series connection one expansion tank between Air compressor and oxygenerator is to satisfy the requirement of oxygenerator for input service air pressure.
The freeing pipe of described oxygenerator bottom is connected with exhaust gas silencer downwards, to eliminate because of the air pressure instability of input oxygenerator or the operation noise that too high need cause.
Use the oxygen-supplying device in rail vehicle of above-mentioned technical characterictic, described method for supplying oxygen is to be provided with oxygenerator in car body inside, the supply air line of described oxygenerator is connected in car body in-to-in air delivery duct, carries prepared oxygen in disperse oxygen supply mode to interior by the wind circulation of air delivery duct;
The supply air line of described oxygenerator is connected in the oxygen supply arm of interior to be formed, and forms in the distributing oxygen supply mode by the oxygen supply arm, provides oxygen outlet at each seat place of interior.
More specifically the disperse method for supplying oxygen is, the supply air line of oxygenerator is connected in the both sides of air delivery duct, car body top, and in oxygen that oxygenerator makes and the air delivery duct behind the air-blending, the air outlet by the car body top veers away to vehicle environment;
More specifically the distributing oxygen supply method is, distributing oxygen supply arm composition is provided with an exhaust pipe mouth at each seat place, and the oxygen that oxygenerator makes directly veers away to vehicle environment from seat.
And described disperse oxygen supply, behind the air-blending that oxygen that oxygenerator makes and car body top interior environment system are sent, the air delivery duct by interior environment system veers away to vehicle environment.
Content to sum up, described oxygen-supplying device in rail vehicle and method thereof have the following advantages:
1, adopts integral type oxygenerator and realize the method for supplying oxygen that disperse oxygen supply and distributing oxygen supply combine, integrally improve oxygen concentration at interior, easy to operate, oxygen concentration can be regulated and monitor as required, solves whole passengers' oxygen uptake requirement in the same time.
2, supply air line is connected with the air delivery duct of car body air-conditioning, can realize the temperature of interior circulating air, the equilibrium adjusting of oxygen concentration simultaneously, and more comfortable environment by bus is provided.
