METHOD FOR DISPERSING A GAS CLOUD AND APPARATUS FOR CARRYING OUT SAID METHOD

摘要

In the event of gas leaking from an above-ground container, horizontal spreading of the developing gas cloud is restricted by the formation of a liquid film on a mesh enclosure mounted around the container. The film is formed by spraying of the liquid. The gas cloud is diluted with air to safe concentration levels by restricting the vertical movement of the gas cloud in the enclosed area and dividing the gas cloud escaping from said area into separate flows. The apparatus for dispersing the gas cloud comprises a solid enclosure which is mounted around the container and on the upper edge of which at least one mesh enclosure is mounted. Reservoir jets which are oriented towards the mesh enclosure are connected to a source of the liquid. A cover having openings into which pipes are mounted is fixed on the upper edge of the mesh enclosure. Gas and thermal radiation detectors are arranged between the container and the mesh enclosure and are connected to a system for controlling the supply of liquid into the reservoir with the jets.
