Description
Technical field
The utility model relates to a kind of gas discriminating gear, particularly a kind of discriminating gear of smoke poisoning gas.
Background technology
Material is meeting evolved gas when heating, and combustible material can disengage flue gas when burning, and these cigarettes, gas have a strong impact on personnel escape, and the poisonous gas containing in flue gas can increase the weight of harm.When hydrogeneous in material, can produce H
2o, carbon containing can produce CO
2, can produce CO during rough burning, chloridely may produce Cl
2, HCl, carbon containing, chlorine may produce COCl
2, nitrogenously may produce NO
x, nitrogenous, hydrogen may produce NH
3, sulfur-bearing may produce H
2s, SO
2, hydrogeneous, carbon, nitrogen may produce HCN.In these representative gases, CO is most important harmful toxic matter in fire smoke, is also lethal primary toxic gas; The irritative gas that the HCl of take is representative, if existed, be the earliest by people's perception, reach the earliest the primary toxic gas of critical value; CO
2be one of main products of combustion of fire, in some scene of a fire, its concentration can reach 15%.Although the toxicity of CO is CO
2100 times, but under naked light combustion case, CO
2be only the main reason that causes people's stupor; Cl
2eyes, the upper respiratory tract and lung tissue are had to spread effect, cause shed tears, sneeze, cough and pulmonary emphysema, cause expiratory dyspnea and suffocate; COCl
2bronchus, alveolar are had to spread effect, cause pulmonary emphysema, cause expiratory dyspnea and suffocate; NO
2bronchus, alveolar are had to spread effect, cause pulmonary emphysema, cause expiratory dyspnea and suffocate; NH
3stimulate eyes and upper respiratory tract mucous membrane, cause pulmonary emphysema; H
2during S low concentration, eyes and upper respiratory tract mucous membrane are had to spread effect, during high concentration, can cause respiratory center paralysis; SO
2eyes, upper respiratory tract bronchial mucosa are had to spread effect, cause lung glottis wind-puff, cause tracheae to stop up and suffocate; HCN is hypertoxic choke damp, is the primary toxic gas that causes losing escape capability.
As cotton, timber, meeting in pyrolytic process produces a considerable number of, to have intense stimulus effect aldehydes and acid to the material of occurring in nature, but in flaming combustion situation, is easily burned and decompose; Along with scientific and technological development, polymkeric substance replaces other material as various materials, such as being used as the principal ingredient of the outer insulation jacket of electric wire, be that superpolymer is as plastics (Polyvinylchloride, cross-linked polrvinyl chloride, tygon, teflon, fluoroplastic, polystyrene etc.), rubber and rubber, the cable of some specific use also has many additives, and the smoke components of generation is more complicated.Therefore, poisonous gas contained in flue gas is differentiated and measured, be subject to people always and pay close attention to, but very difficult to toxicity evaluation and the analysis of material thermal decomposition or burning generation flue gas, conventionally adopt the toxic gas potpourri that material combustion discharges to evaluate the group effect of animal.The poisonous gas disengaging during at present for material combustion is measured, the product smoke toxicity test device that adopts GB GB/T 20285-2006 (with reference to DIN 53436 JIS A1321 standards) to produce, it is the testing equipment that a kind of test material burning produces the toxic grade of flue gas, first by material combustion, by the test in mouse cage in toxicant exposure box, with white mouse, carry out biological toxicity test, belong to animal and expose viral infection test, can not differentiate the concrete composition of gas.
