Description
Technical field
The utility model relates to a kind of portable breathing apparatus, be particularly related to a kind of portable compressed air purifying respiratory system, it can utilize the compressed air being seen everywhere under the working environments such as factory floor, by purification, make it to reach breathe air quality standard and supply with people and breathe use, reaching the object of respiratory protection.
Background technology
There are at present two kinds of systems for helping the people of contaminated air invasion and attack to breathe.The first is power respirator (SCBA---provide breathing apparatus for oneself), and it will compress (for example bottled) air and be transported to close-fitting face shield or lead to mouth and/or other conduit of nose, for user, suck.These systems do not allow the atmosphere of user's contact environment.The second is the filter/decontamination systems of using with canister form, it with depend on cleaning ambient air so that the respirator apparatus of its respirability is connected.Auxiliary power can be used or do not used to this filtration system.In dynamical system, ambient air is inhaled into by suitable filter/decontamination plant or other purifier under the effect of power fan etc., thereby makes the surrounding air polluting again become the air that can breathe.The air that purification obtains is sent to certain helmet, close-fitting face shield (whole system is called as powered air purifying respirator (PAPR)) for example.These two kinds of respiratory auxiliary systems all can be for librarian use that must breathing environment atmosphere, and this air be considered to be subject to severe contamination, should not breathe or dangerous air.
The dangerous atmosphere that should not breathe is considered to the air that the volumn concentration of oxygen is less than 19.5, although contain essential oxygen, also contains a large amount of noxious pollutants, as the air of particle or gas is also considered to contaminated and harmful simultaneously.Be understood that, (wherein oxygen content is at least 19.5%) in some cases, wearer only need use filtration system just can enter atmosphere pollution area, if this filter can tackle the challenge of pollution, Cleaning Air, can allow this user breathe, and still make it keep fit thus.This filter can be equipped with the device that can remove the harmful components in wearer's ambient air.Particularly, take decontamination system as basic filter, be exactly those ambient airs that can purify contaminated, and make it be converted into the system of the air that can breathe.When transmitting air-source by purification (as suitable filter) under normal pressure, these systems work best.That is to say, use pump/fan to draw contaminated atmosphere, make it pass through a filter, contact with the material that improves pollutant, and force subsequently and to have purified, the air after filtering enters face shield or other device, for example mouth mask, head-shield or helmet relevant with wearer's breathing under normal pressure.Although can preferred power-actuated air supply device, for example battery-driven pump/fan class device, also knows and can use the air cleaning system driving without external device (ED).In those non-dynamical systems, the power of user lung provides necessary motive force, thereby forces contaminated air by purification, then flows to user.For for simplicity, this device of environment purification atmosphere will be called as air-purifying respirator (APR).When owing to using battery, line current or other kinetic pump or fan class device to force air to pass through this system, these operating systems are called as powered air purifying respirator (PAPR).
As long as the percent by volume of oxygen is more than 19.5 in the air purifying; and as long as pollutant is the pollutant that can remove by filtration; as cigarette ash and flue dust; and/or can react by the cleaning of substances with suitable the pollutant improving, powered air purifying respirator (PAPR) just can protect wearer to avoid the evil of pollutant.With regard to actual effect, these systems can be designed to be used in removable filter and air cleaning tank.Yet the volume content of oxygen is lower than 19.5% time in ambient air, these systems will be valueless at all.
Also have other situation, for example ambient air is seriously polluted, pollute so seriously in other words, to such an extent as to filter and/or decontamination/cleaning system cannot be processed this problem; And/or the oxygen content in surrounding air is too low, to such an extent as to cannot meet people's living necessities (that is to say, atmosphere is IDLH, and the meaning is that ambient air is direct life-threatening and health) here.In these cases, people, when entering the region with level of pollution like this and type, must carry the air-source of oneself.This is similar to diver and carries the air of oneself with the container (bottle) that compression clean air is housed.
In a large amount of contaminated environment, there is the compressed air gas source using as power, but can not be as respiratory gas source because this source of the gas itself is unholiness, if exist a kind of equipment and can be converted into breath by this gas source purification, so just can solve the respiratory protection problem under this contaminated environment.
Be understood that, when confined space operation, as: at cabin, tank case, pressure vessel, the small spaces such as pipeline are engaged in welding, polishing, clean, during upkeep operation, surrounding air often can be heavily polluted and have even anoxic of a large amount of poisonous and harmful substances, self-priming filtering type dust-proof rebreather or respirator for gas defence are meaningless under this environment, the people that enter this region operation must carry in addition other sources of the gas and blow and could solve respiratory protection problem as gas cylinder or by long tube, no person can suffocate because of anoxic, or be subject to the infringement of other pollutant.
When carrying air-source, for how many air can be carried safely, there is a very real practical limits.With to use under water SCUBA equipment to operate contrary, fireman's gas cylinder used is quite heavy, and must be supported completely by wearer, nor can utilize buoyancy of water partly to support their weight.They are done more to a little, thereby can carry more air, but increased their weight like this, reduced their portability.
Therefore, under such working environment, as long as have the compressed air gas source as power, there is again a kind of equipment to breathe quality standard for user's breathing by reaching after this gas source purification simultaneously, just the respiratory protection of the people of operation under this contaminated environment can be thoroughly solved, and toxic and harmful or anoxic whether needn't be worried whether to exist in air.And can solve long-time respiratory protection and needn't worry matter of time.
Certainly, this equipment, except purification function, also needs the normally breathing mask of comfortable wearing, so just can be combined into complete a set of compressed air breath purifying system.
