Abstract
A device for filtering a flow of gas conveying liquid or solid particles in a flow channel. According to the invention, the particles are imparted a speed that is high enough to project same by inertia into the opening of a recovery channel formed inside the flow channel, while the gas from the flow bypasses said opening due to a specific configuration of the flow conditions of a perfect fluid in the flow channel and in the collection channel.
Claims11
A device for filtering a flow of gas conveying liquid or solid particles, said device comprising:
- a flow channel comprising a neck extended by an enlargement in the downstream direction,
- a recovery channel having an upstream opening arranged inside the flow channel so as to be substantially aligned with the neck in the downstream extension thereof,
- with the recovery channel and the flow channel being so configured that the flow allowed to circulate in the recovery channel is less than the one allowed to circulate in the flow channel.
The method for filtering a flow of gas conveying liquid or solid particles along a path, with said method being such that:
- on said path is placed a recovery channel having an upstream opening arranged inside a flow channel which comprises a neck extended by an enlargement in the downstream direction, so that said upstream opening is substantially aligned with the neck, along a downstream extension thereof,
- and is allowed to circulate, in the recovery channel, a flow which is less than the one allowed to circulate in the flow channel.
