SU6833A1 - Explosion safeguard for storage of flammable liquids - Google Patents

Description

Patent No. 1022 describes an explosion guard of storages of highly flammable liquids, consisting of several thin-walled tubes entering one another, covered with a special plate on the cork, sunk or melted metal, and fitted with non-coincident rows of small holes. The effect of this fuse is that when the hrayilisch is hit by a fire, the fusible melt melts, vapors formed from the heating of the liquid rush through the fuse and ignite, but the flame enters the inner tube and the passage of narrow spaces between the tubes breaks and goes out.

The present invention aims to use these fuses to protect the vaults from explosions that may occur as a result of electrization of the fluid from friction against the walls of pipelines.

In FIG. 1 shows a vertical section of the present invention along line a b in FIG. 2; FIG. 2- view of the fuse from above.

The fuses 9, 9 are mounted on the periphery of the round metal

a pot 5 with thick walls, a seed cap 4 and a bottom 7. Such a pot is located inside or outside the tank with easily flammable liquid, at the end of the pipeline 1 filling the tank.

The fluid striking the bottom of the pot loses its speed, and the negative electrical charge of the fluid is carried out with the positive electricity of the walls of the pot 5.

With discharge occurring and if there is an explosive mixture in pot 5 at the beginning of filling the tank, an explosion may occur, but since the quantity of the mixture is small and the walls of the pot are calculated for such pressure, the pot will not break and the flame will not be transferred to the tank. due to the presence of fuses 9, 9. Secondary electrification of the liquid will not occur, since the path for getting liquid into the tank and its speed, with a sufficient number of fuses, is small.

The subject of the patent.

The use of a fuse from explosions of storages of flammable liquids according to patent No. 1022 in the form

- four,

groups of such fuses, installed along (alternately) metal cfroiCTHMH walls and with a seed lid and bottom of the pot 5, placed or outside of tanks storing the mentioned liquids and located on the end of the pipeline with these liquids, in order to fill the jster with the help of a large number of small jets, in order to avoid dangerous electrical discharges resulting from the friction of fluid against the walls of the pipeline.
