Abstract
The invention provides a chemical oxygen-making respirator for normal temperature phase change material refrigeration, and belongs to the field of fire fighting and rescuing. The oxygen-making respirator comprises a mask, an oxygen-producing purifier, an air bag, a cooler, a battery, a GPS (Global Positioning System) controller and other parts, wherein gas enters the oxygen-producing purifier through the mask and an respiration pipeline when the respirator works, carbon dioxide reacts with medicaments in the purifier to produce oxygen; oxygen is stored in the air bag in an expiration process; and gas flowing from the air bag is cooled by the cooler in an inspiration process, and enters the mask for respiration through the pipeline. The cooler in the respirator is used for refrigerating and cooling by utilizing a normal temperature phase change material. The chemical oxygen-making respirator can be used for overcoming the defect that refrigeration and cooling of the traditional respirator is not convenient to use by requiring electricity or ice serving as refrigerating materials, and has the advantages of simple structure, convenience in use and convenience in supply.
Description
Technical field
The invention belongs to the fire-extinguishing and lifesaving field; Be applicable to that fire-fighting, colliery, chemical industry, tunnel and skyscraper etc. detect and wear use in the work in the disaster environment rescue and relief work of poisonous, pernicious gas, anoxic, search; Relate to a kind of chemical formula system oxygen inhalation apparatus, the emergency survival breathing equipment that particularly a kind of chemical oxygen generation, purification and freezing by change of state are used.
Background technology
Respirator prevents that human body from sucking a kind of respiratory protection utensil of carrying of poisonous gas poisoning or anoxia asphyxia when being accident such as well or protected personnel breaking out of fire in down-hole or particular surroundings, gas, coal-dust explosion.When various accident takes place its main application exactly, supply the user of service to wear and escape danger, avoid poisoning or death by suffocation; Be applicable in the places such as sea-freight steamer, underground railway, pernicious gas thesaurus, public place of entertainment, megastore and high-rise resident building.In order to satisfy the requirement of escaping and giving first aid under the particular surroundings; Many in the world countries have strengthened the research to various respirators, have developed various respiratory devices such as fume respirator, chemical oxygen respirator, compressed oxygen (air) respirator and fire-fighting self-rescue apparatus step by step.
Fume respirator on principle, is only applicable to carbon monoxide and hydrogen cyanide is in the environment of harmful components, can not protect other toxic and harmfuls, and it is also inapplicable that oxygen concentration is lower than 17% environment.Simultaneously, the use of various New Building Materials and organic finishing, ornament materials in the actual life, these material combustions produce the floating thing that has viscosity, stick on the filter bed of filtering type self-rescue apparatus, and resistance increased when the people was used, expiratory dyspnea.Therefore, fume respirator has the trend that progressively is eliminated in colliery and other environment.
The basic principle of compressed oxygen respirator is with O
2Be stored in the pressure vessel, utilize pressure reducer during use high pressure O
2Pressure reduce, by quantitative oxygen supply, automatically the supply oxygen supply and manually supply oxygen supply mode satisfy the human body respiration needs, the foul smell of exhalation is through Ca (OH)
2Get into respiration cycle after the purification once more.The compressed oxygen respirator is applicable to any disaster area environment, and can view O intuitively
2Pressure, the wearer can the estimated remaining time.But its shortcoming is that the volume and the quality of respirator is bigger than normal, and service time is too short, and need regularly carry out care and maintenance.
More than two kinds of respirators also have a common shortcoming, promptly under the too high situation of environment temperature, respirator is difficult to use.
Summary of the invention
For solving the problem that the lifesaving of fire fighter's fire-fighting occasion is breathed, the invention provides a kind of chemical legal system oxygen that utilizes, the emergency survival breathing equipment of phase-change material cooling.
A kind of chemical oxygen generation respirator of normal temperature phase-change material refrigeration: the method for producing oxygen through chemistry provides oxygen and with the carbon dioxide purification, through cooler gas cooled is arrived the temperature that suitable people breathes.Cooler adopts the mode of freezing by change of state to cool off, the phase-change material that cooler adopts be melting point between 5 degrees centigrade to 35 degrees centigrade, melting heat at 100kJ/kg between the 2000kJ/kg.Producing the medicament that is adopted in the oxygen clarifier is KO
2Or Na O
2
Said chemical oxygen generation respirator is mainly by forming with the lower part: parts such as face shield-1, product oxygen clarifier-2, air bag-3, cooler-4 are formed.The gas that the people breathes out is through face shield-1 and breathe pipeline entering product oxygen clarifier-2; The reaction of carbon dioxide and medicament produces oxygen in producing oxygen clarifier-2; Oxygen gets into air bag-3 and stores in exhalation process; In breathing process, the oxygen rich gas in the air bag supplies the people to breathe use through pipeline, face shield-1 after cooler-4 is regulated temperature.Breathing gas circulates in totally-enclosed system, with the external world Gas Exchange does not take place, and can effectively stop pernicious gas to get into respiratory system.
For realizing the accurate location of rescue personnel present position, battery-5, GPS controller-6 have been installed in the present invention additional in the chemical oxygen generation respirator, and battery-5 links to each other with GPS controller-6.
Self-saving breather of chemical oxygen is the respirator of a kind of respiratory circulatory system and insulated from ambient atmospheric conditions (being totally-enclosed self-circulation system), and it utilizes regenerative agent and steam, CO
2Reaction sponges the CO in the expiration
2, producing oxygen simultaneously supplies the people to breathe usefulness, and this is big characteristics of Self-saving breather of chemical oxygen.Another big characteristics are that cooling system can be set.Thereby it does not receive the restriction of ambient atmosphere environmental gas composition, under anoxic, hot environment and the occasion of poisonous gas leakage also can be suitable for, be a kind of comparatively desirable self-rescue apparatus.
The beneficial effect of this device is following:
(1) breathing gas circulates in totally-enclosed system, with the external world Gas Exchange does not take place, and can effectively stop pernicious gas to get into respiratory system.
(2) produce the oxygen clarifier and can realize the function removing carbon dioxide in air, produce oxygen in exhalation process simultaneously.
(3) adopt normal temperature phase-change material refrigeration in the cooler, need not extra power supply, and the refrigerating material convenient for storing can be recycled.
(4) carry the GPS controller in the system oxygen inhalation apparatus,, can effectively confirm rescue personnel's position through control centre.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is this chemical oxygen generation respirator sketch map
The 1-face shield, 2-produces oxygen clarifier, 3-air bag, 4-cooler, 5-battery, 6-GPS controller.
The specific embodiment
Embodiment
As shown in Figure 1, a kind of chemical oxygen generation respirator, the gas that human body is breathed out is equipped with KO through face shield-1 and the entering of breathing pipeline
