Gas film with firefighting and smoke exhausting functions

Abstract

The invention relates to the field of gas films, in particular to a gas film with firefighting and smoke exhausting functions. The gas film comprises an inner film, an outer film and a smoke exhausting component. The inner film is fixedly arranged on the outer film via a connecting piece, at least two cavities are formed by the inner film, the outer film and the connecting piece and are communicated with each other, open holes which correspond to one another are formed in the inner film and the outer film, the smoke exhausting component is arranged at the open holes, and the outer edge of thesmoke exhausting component is hermetically connected with the inner film and the outer film. The gas film has the advantages that the open holes which correspond to one another are formed in the innerfilm and the outer film, the smoke exhausting component is arranged at the open holes and can be switched on when fire hazards occur, the inner gas pressures of the gas film are higher than the external air pressures, dense smoke generated during combustion can be exhausted out of the gas film by the smoke exhausting component, and accordingly harm on personnel in the gas film due to the high temperatures and mixed toxic gas can be reduced to a great extent; the high-temperature dense smoke can be effectively exhausted, accordingly, the spreading speed of open fire can be effectively reduced,the visual field ranges of the personnel in the gas film can be expanded, and the precious time can be gained for escape.

Description

technical field [0001] The invention relates to the field of air film, in particular to an air film with fire-fighting and smoke exhaust. Background technique [0002] At present, in the prior art, due to the structural characteristics of the air film, there is no fire-fighting and smoke exhaust channel. Once a fire occurs, the smoke generated by the open flame cannot be discharged. The main cause of death caused by thick smoke is carbon monoxide poisoning. In the air with a carbon monoxide concentration of 1.3%, a person will lose consciousness after breathing two or three breaths, and will die after breathing for 13 minutes; it is known that the content of carbon monoxide in the smoke produced when commonly used building materials are burned is as high as 2.5%. In addition, the smoke in the fire also contains a large amount of carbon dioxide. Under normal circumstances, carbon dioxide accounts for about 0.06% in the air. When its concentration reaches 2%, people will feel...
