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 fire-extinguishing and lifesaving field, be applicable to fire-fighting, colliery, chemical industry, tunnel and skyscraper etc. and in detecting work, wear use in disaster environment rescue and relief work, the search of poisonous, pernicious gas, anoxic, relate to a kind of chemical formula oxygen respirator, particularly the emergency survival breathing equipment of a kind of chemical oxygen generation, purification and freezing by change of state application.
Background technology
Respirator prevents while being the accidents such as well or protected personnel breaking out of fire in down-hole or particular surroundings, gas, coal-dust explosion that human body from sucking a kind of respiratory protection utensil of carrying of poisonous gas poisoning or anoxia asphyxia.When its main application exactly various accident occurs, wear and escape danger for user of service, avoid poisoning or death by suffocation; Be applicable to transport by sea in the places such as steamer, underground railway, pernicious gas thesaurus, public place of entertainment, megastore and high-rise civil construction.In order to meet the requirement of escaping and giving first aid under particular surroundings, many countries have strengthened the research to various respirators in the world, have developed step by step the various respiratory devices such as fume respirator, chemical oxygen respirator, compressed oxygen (air) respirator and saving oneself respirator.
Fume respirator is only applicable to, in environment that carbon monoxide and hydrogen cyanide are harmful components, can not protect other toxic and harmfuls in principle, and also inapplicable lower than 17% environment to oxygen concentration.Meanwhile, the use of various New Building Materials and organic finishing, ornament materials in actual life, these material combustions produce and are with sticking floating thing, stick on the filter bed of filtering type self-saving respirator resistance increment when people is used, expiratory dyspnea.Therefore, fume respirator has the trend being progressively eliminated in colliery and other environment.
The general principle of compressed oxygen respirator is by O
2be stored in pressure vessel, when use, utilize pressure reducer by high pressure O
2pressure decreased, by quantitative oxygen supply, automatic makeup to oxygen supply and manually supply oxygen supply mode meet human body respiration needs, the foul smell of exhalation is through Ca (OH)
2after purification, again enter respiration cycle.Compressed oxygen respirator is applicable to any disaster area environment, and can view intuitively O
2pressure, wearer can estimate remaining time.But its shortcoming is that volume and the quality of respirator is bigger than normal, and service time is too short, and need to regularly carry out care and maintenance.
Above two kinds of respirators also have a common shortcoming, and, in the situation that environment temperature is too high, respirator is difficult to use.
Summary of the invention
The problem of breathing for solving the lifesaving of fire fighter's fire-fighting occasion, the invention provides one and utilizes chemical method oxygen, the emergency survival breathing equipment that phase-change material is cooling.
A kind of chemical oxygen generation respirator of normal temperature phase-change material refrigeration: oxygen is provided and carbon dioxide is purified by the method for chemical oxygen-producing, the temperature of gas cooled being breathed to applicable people by cooler.It is cooling that cooler adopts the mode of freezing by change of state to carry out, the phase-change material that cooler adopts be melting point between 5 degrees Celsius to 35 degrees Celsius, melting heat at 100kJ/kg between 2000kJ/kg.Producing the medicament adopting in oxygen clarifier is KO
2or Na O
2.
Described chemical oxygen generation respirator is mainly made up of following part: the parts such as face shield-1, product oxygen clarifier-2, air bag-3, cooler-4 form.People breathe out gas through face shield-1 and breathing pipeline enter produce oxygen clarifier-2, in product oxygen clarifier-2, interior carbon dioxide reacts and produces oxygen with medicament, oxygen enters air bag-3 and stores in exhalation process, in breathing process, oxygen rich gas in air bag, after cooler-4 regulate temperature, is breathed for people through pipeline, face shield-1.Breathing gas circulates in totally-enclosed system, with the external world, gas exchange does not occur, and can effectively stop pernicious gas to enter 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 chemical oxygen generation respirator, and battery-5 are connected 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 expiration
2, producing oxygen and breathe for people simultaneously, this is a large feature of Self-saving breather of chemical oxygen.Another large feature is that cooling system can be set.Thereby it is not subject to 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 as follows:
(1) breathing gas circulates in totally-enclosed system, with the external world, gas exchange does not occur, and can effectively stop pernicious gas to enter respiratory system.
(2) produce oxygen clarifier and can realize the function of removing airborne carbon dioxide, oxygen producing in exhalation process simultaneously.
(3) in cooler, adopt normal temperature phase-change material refrigeration, without extra power supply, and refrigerating material storage conveniently can be recycled.
(4) in oxygen respirator, carry GPS controller, by control centre, can effectively determine rescue personnel's position.
Brief description of the drawings
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is this chemical oxygen generation respirator schematic diagram
1-face shield, 2-produces oxygen clarifier, 3-air bag, 4-cooler, 5-battery, 6-GPS controller.
