Description
Technical field
The utility model is related to a kind of civilian escape system more particularly to a kind of escape systems of assisted respiartion.
Background technology
Recently as expanding economy, the level of urbanization in China is continuously improved, and urban population increases and urban construction
Land used supply is insufficient particularly thorny, and in order to alleviate this contradiction, people's residential location tends to high stratification.In addition, the current people
Living conditions be also continuously improved.House interior trim, household goods and displaying articles are all being enriched constantly.The improvement of living conditions
The comfort of people's inhabitation is substantially increased, but exists simultaneously fire safety evaluating hidden danger.Main cause is：1）House interior trim, furniture
Articles for use and displaying articles are mostly the combustibles such as timber, plastics and fabric.When once catching fire, these material combustions, which can discharge, to be had
Malicious pernicious gas.2）People's residential location is in high level.When catching fire, the people need the regular hour to flee from the scene of the accident.
Many fire incidents in reality, accident personnel are not scorched to death, but because toxic and harmful gas leads to death by suffocation.
Therefore as residential locations such as public place of entertainment, shops and houses, being equipped with private residence escape system will be extremely important.When generation fire
When, user of service can wear this system and not fled the scene quickly by the harm of toxic and harmful gas.
Common escape system is divided into filtering type and Gas feeding, two kinds of operation principle differences on the market at present.Filtering type master
It will be by filtering the toxic and harmful gas ingredient in ambient air, to realize that user of service breathes safety air.It is this
There are many kinds of the types of form, but structure is similar, and filtering type mainly protects head using aluminium foil head-shield, matches on head-shield
There is canister.Air in hazardous environment enters head-shield by canister filtering, breathes and uses for survivor.Gas feeding mainly leads to
It crosses and carries safe air source, breathed for user of service.Gas feeding generally comprises gas cylinder, cylinder valve pressure reducer, supply air line and head-shield.
High pressure gas in gas cylinder, by cylinder valve pressure reducer at middle pressure, output gas enters head-shield by supply air line, for user of service
Breathing is used.The gaseous mixture of exhalation is discharged by the outlet valve on head-shield.
Current filtering type escape system is provided with filtering tank, is filled using activated carbon as main component in filtering tank, and
The pore surface of activated carbon, impregnated of chemical agents such as copper, silver, chromium metal oxides.But the filtering tank of different model, filtering
Noxious gas component it is different.But indoor interior decoration and displaying articles include timber, plastics, textile and fiber etc. can
Combustion things, these material combustions will produce various pernicious gases, and filtering type escape system on the market, different model are only capable of at present
Certain toxic gas is filtered, whole toxic and harmful gas cannot can be filtered, filter effect is barely satisfactory, i.e., enabled auxiliary
Escape still has certain damage to human body.In addition, after user of service takes head-shield, gas volume in head-shield when air-breathing
It reduces, negative pressure is in head-shield so that head-shield neck seal can not achieve 100% sealing, and surrounding pernicious gas can not pass through filtering
Tank and enter head-shield from neck seal, to endanger the life security of user of service.
Current Gas feeding escape system carries air supply source, and head-shield is in positive pressure in the course of work, and can overcome has poison gas
Body endangers the risk of user of service's life security, but existing Gas feeding escape system mostly uses greatly using 2.2L, gas cylinder work
Make the aluminium alloy gas cylinder of pressure 20MPa, the big weight weight of volume does not meet the performance of user of service more preferably.If simple
The nominal volume that ground reduces gas cylinder can seriously threaten the personal safety of user of service in this way then service life will be sacrificed.By
It is generally higher in current inhabitation floor, in order to ensure that personnel efficiently flee from the scene of the accident, it is badly in need of a small in volume, and
Enough service lifes are can guarantee, to ensure escape system that user of service leaves safely.
