SU1235506A1 - Apparatus for suppressing explosion - Google Patents

Description

The invention relates to devices for delivering extinguishing agent to the explosion zone and can be used in closed-volume explosion suppression systems, for example, in process equipment of the chemical industry.

The purpose of the invention is to simplify the design and increase reliability.

The drawing shows suggesting my device, a cut.

The device consists of a housing 1 filled with fire extinguishing agent 2 with a fixed spray nozzle 3 having openings 4 and placed in the lower part of the housing, a piston 5 serving to displace the fire extinguishing agent, a pyrotechnic 6, membranes 7 serving to seal the housing, and a movable the spray nozzle 8 with holes placed between the piston 5 and the fixed nozzle 3. In this case the movable spray nozzle is installed with the possibility of longitudinal movement relative to the body and the hole in the fixed asadke made slotted.

The device works as follows.

When pyrobudger 6 is triggered, the formed powder gases destroy the upper membrane 7. Under the action of pressure, the piston 5 starts

5 is moved, the lower membrane 7 is destroyed, and the extinguishing agent 2 (freon 114B2) is injected at high speed into the explosion zone. The initial portion of the extinguishing agent 10 is injected through a fixed spray nozzle 3, having a slit perforation 4, which provides high speed and range of drops of freon

15 114B2. As the piston 5 moves, the movable nozzle 8 moves under the action of the flow of extinguishing fluid 2. As soon as the movable nozzle 8 reaches the stationary 20 cage 3, the release of the extinguishing agent in the form of finely sprayed jets begins through the openings of the movable nozzle. The outflow occurs only through those holes nozzle 8,

25 which: e did not coincide with the slits in the nozzle 3, i.e. At the same time as the mass flow rate of the extinguishing fluid decreases, the structure of the oroshe torch 30 itself also changes in the direction of decreasing droplet size.
