| 简介 |
Useful model relates to the field of rescue equipment, in particular to means of individual protection of respiratory organs, operating on chemically bound oxygen, and can be used, for example, in structure samospasatelei for underground operations. Technical result of the utility model is to moistening respiratory gas mixture and diffusion lu cooling efficiency of its. Is a device for cooling respiratory gas mix in equipment of individual protection of respiratory organs, operating on chemically bound oxygen, including insert 1, installed on the path of motion of respiratory mixture, inside of which is placed coolant. The essence of the utility model consists in the fact, that in is used as cooling agent inorganic salts, are able to form crystallohydrates, applied on fibers. As such salts can be used salts of calcium and magnesium, of individual and mixed salt of the ferric iron, aluminium, rare-earth elements and others. Fibers 6, on which is applied salt, able to form crystallohydrates, is manufactured from inorganic compounds, for example, glass, quartz, basalt, aluminium oxide and others. For fixation of treated fibers insert has both sides of holding net 4 and 5, made from stainless steel. The offered device allows reduced temperature respiratory mixture to safe parameters of, to increase moisture content and simplified maintenance means protection of respiratory organs. 3 3. u. 2 ., 1 ill. |
