SEPARATION AND RECOVERY APPARATUS

摘要

PROBLEM TO BE SOLVED: To improve working efficiency of an absorbent and to improve recovery efficiency by providing a shutter with gas permeability constituted in such a way that a slit with a uniform width through which the absorbent flows out moves in the horizontal direction on the discharging outlet of a hopper in a discharging machine for controlling discharge from an absorption tower. SOLUTION: An absorption tower 2 is provided with a feeding inlet 17 for feeding a regenerated unabsorbed agent 1E and is constituted of an absorption tower main body 19 in which a heat exchanging means is combined and a hopper 13 for introducing a mixed gas (a feedstock gas) in which an ingredient to be recovered is mixed from a discharging outlet 11 and discharging an already absorbed agent 1F absorbs the ingredient to be recovered. A discharging machine 3 is attached to the discharging outlet 11 so as to perform discharging of the already absorbed agent 1F in the absorption tower 2 while it is balanced with reaction speed in a regenerating tower 4. Here, the discharging machine 3 provided with a shutter 15 constituted in such a way that a slit 14 with a uniform width through which the absorbent 1 flows out moves in the horizontal direction on the discharging outlet 11 of the hopper 13 and with gas permeability, is attached to the discharging outlet 11.
