Device for discharging an explosive gas
A device for releasing an explosive gas via a stack arranged on a roof of a building is provided. The upper free end of the stack is provided with a discharging head including a plurality of distribution pipes projecting from the stack in the form of a star. Each pipe includes an outlet on the free end thereof. The device reduces the pressure wave load exerted during an explosion even during adverse wind conditions. To this end, the end regions of the distribution pipes are embodied as jet pumps in which the explosive gas is the propellant sucking the ambient air.
1. A device for discharging an explosive gas, comprising:
a stack that is arranged on a roof of a building; and
a discharging head that comprises a plurality of distributor pipes emanating in a star shape from the stack,
wherein the discharging head is provided on an upper free end of the stack, and
wherein the plurality of distributor pipes each include at a free end an exit opening, and
wherein an end region of each of the plurality of distributor pipes is designed as a jet pump in which the explosive gas is a motive medium that takes in ambient air; and
wherein the plurality of distributor pipes are arranged in two levels, providing exit openings in a lower level and providing exit openings in an upper level,
wherein each jet pump includes a driving nozzle,
a diffuser, and a mixing chamber adjacent to the nozzle, where the ambient air is sucked in due to an underpressure set up in the diffuser,
wherein the driving nozzle is substantially arranged within the mixing chamber,
wherein the intake ambient air is mixed with the explosive gas in the diffuser disposed after the mixing chamber in a flow direction, and
wherein the mixture is blown out of the exit opening, and
wherein the plurality of distributor pipes of the upper level are inclined upward at a prescribed angle with respect to the roof, and
wherein the plurality of distributor pipes of the lower level are arranged horizontally with respect to the roof,
wherein the plurality of distributor pipes of the upper level and the plurality of distributor pipes of the lower are arranged in an alternating manner such that an angular offset with respect to the vertical axis of the stack exists between each distributor pipe of the upper level and an adjacent distributor pipe of the lower level.
