A ventilation device consists of a camera and openings, an explosion-proof element in the form of a disk made from acid-proof material and combined reflector and electrolyte aerosols trap made as a labyrinth of cylindrical form. The labyrinth has at least two camera of labyrinth arranged one above another and formed with narrow parts of labyrinth separated by two wide parts of labyrinths close adjacent to a ventilation device body. On wide parts of labyrinth it is made two cuts formed with the ventilation device body two gaps for gas passing, cuts at adjacent parts, which restrict one labyrinth camera located &pgr;/2 angle one relatively another, maximum wide of gap formed with cuts is 0,1-0,3 part of wide labyrinth side radius. Correlation of narrow and wide parts radii of labyrinth is within limits of 2-4, correlation of heights of narrow and wide parts of labyrinth is within limits of 0,5-2,0. |
