Liquid distributor

A gravity liquid distributor comprising:

• a lower plate (P) provided with orifices via which a liquid leaves the distributor in order to irrigate a lower element, such as a lower packing section,
• parallel parallelepipedal chimneys (C) dedicated to the passage of the ascending gas, thus delimiting troughs for liquid above the lower plate, the parallel parallelepipedal chimneys being provided with a closure means on the upper portion, configured both to deflect the liquid, and to mechanically support this section,
• the parallel parallelepipedal chimneys are distributed over an entire central portion with a circular cross section of the lower plate, which frees up a peripheral channel, which is fluidically connected to the troughs, over the perimeter of the lower plate,
• a plurality of hats (R, R1, R2) that are configured to guide the liquid collected above the troughs towards the peripheral channel, each hat having an elongate rectangular form with two ends, wherein:
• there is just one hat per trough, each hat being closed off at just one end and optionally inclined such that at least the majority of the liquid collected flows towards the peripheral channel,
• the hats are oriented at an acute or zero angle with respect to the horizontal, and
• the end of the hats that is closed off alternates from one trough to another.
