Description
Technical field
The present invention relates to a kind of respiratory organ, especially a kind of efficient breather for fire fighting of internal-circulation type.
Background technology
It is known that fireman is when rescuing fire scene rescue scene, on-the-spot CO and or other toxic gas can
The respiratory tract even life of fire-fighting officers and men can be brought harm.The use time of conventional air respiratory organ is the shortest
(6.8L air respiratorresuscitator theory uses the time to be 45 minutes, within time used is 30 minutes), and quality is bigger than normal
(weight of 6.8L air respiratorresuscitator is about 10.2KG).Inferior position on use time and weight greatly limit conventional air and exhales
The use of haustorium, also constrains fire-fighting officers and men in fire, the performance of rescue site.Therefore, design a kind of persistent period length, pendant
Band is simple, bear light Almightiness type breather for fire fighting, is to be presently required to solve the technical problem that.
Summary of the invention
The technical problem to be solved be to provide a kind of persistently use the time, wear simple, bear light
Almightiness type breather for fire fighting.
The present invention solves the technical scheme of its technical scheme:

As a preferred embodiment of the present invention, described unidirectional forced ventilation filter is by particulate filter, air inducing
Machine, harmful gas absorber and check valve are constituted, particulate filter, air-introduced machine, harmful gas absorber and check valve order
Connecting, check valve connects with tee T.When switching switch and being switched to outer circulation respiratory organ pattern, the air that air-introduced machine sucks leads to
Cross and pass through gas after sponging the harmful gass such as CO and SO2 by harmful gas absorber again after particulate filter filters out dust
Room enters face shield and breathes for fireman.
As a preferred embodiment of the present invention, or arrange in air chamber equipped with CO2 suction built with CO2 absorbent at air chamber
Receive the antipriming pipe of agent.When switching switch is switched to interior circulatory and respiratory device pattern formula, and check valve is closed naturally, the oxygen that oxygen candle produces
Being lowered the temperature laggard air inlet chamber by ice chest, the air containing CO2 of fireman's exhalation is also into air chamber, and the CO2 absorbent in air chamber will
CO2 absorbs, and breathes for fireman after other gases of fireman's exhalation and the oxygen mix entered in air chamber.
As a preferred embodiment of the present invention, two oxygen candles are separately fixed on casing and case lid or two by anchor ear
It is each attached on casing.
As a preferred embodiment of the present invention, described particulate filter is the mode of middle effect+efficient folded filter paper,
Middle effect filter paper can remove the bulky grain toxic fumes of more than PM10, and High Efficiency Filter Media can remove the little granule of more than PM2.5 toxic smoke
Dirt, reduces aeration resistance by the mode folded, and improves dust containing capacity；Road filtering layer headed by this filtering layer.
As a preferred embodiment of the present invention, described harmful gas absorber is cavity, at cavity built with being used for
Absorption eliminates the military project activated carbon of the part organic gas in air.
As a preferred embodiment of the present invention, described CO2 absorbent is calcium bicarbonate granule.
The design of oxygen candle:
Calculation of oxygen demand is 1.2L/min, 1.2 × 60=72L by self-rescuer standard oxygen-supplying amount, it is contemplated that people's maximum is aerobic
Measure 3 L/min, therefore this regenerative cartridge is designed as 100L/h；
Oxygen-producing amount is that the design of 100L oxygen candle calculates:
Oxygen candle oxygen sources inDecomposing, its oxygen-producing amount is calculated as follows:；
The oxygen density of existing oxygen candle is=41%, then data V=100L are substituted into and can calculate the matter needing oxygen candle medicine block
Amount (shape can as required depending on): W=0.320kg=320g；
Oxygen candle medicine block Size calculation: medicine block is designed as cylinder, and diameter is set to 30mm, and medicine block density is: long L=320 ÷
1.9÷(1.5×1.5×3.14)=238mm；
Considering oxygen candle domestic demand and load various filtering materials and heat-barrier material, regenerative cartridge profile arrangement is 50mm
×300mm；
Air chamber (purifying carbon dioxide) part design:
Based on single carbon dioxide output 22L/h and effective carbon-dioxide absorbent that carbon dioxide absorption rate is 36%
Calculate, then need carbon-dioxide absorbent 520g；
The density of carbon-dioxide absorbent is: 0.78g/cm3, volume V=520 ÷ 0.78=660cm3.
Compared with prior art, the present invention persistently use the time up to 2-5 hour (being conventional ventilators more than 4 times),
Weight saving 50%, wears simple, bears light, be greatly improved Operational Effectiveness Rat and the health quotient of fire-fighting officers and men.
