FLUID DELIVERY APPARATUS AND METHOD FOR MODIFYING FLUID DELIVERY APPARATUS
A fluid delivery apparatus to deliver a slurry liquid to be brought into contact with exhaust gas discharged from a combustion device to a plurality of delivery destinations comprises: a first delivery line for delivering the slurry liquid from a delivery source to a first delivery destination; a return line, branching off from the first delivery line at a first bifurcation part, for returning the slurry liquid to the delivery source; a second delivery line, branching off from the return line at a second bifurcation part, for delivering the slurry liquid to a second delivery destination different from the first delivery destination; and a delivery destination switching device configured to able to switch a delivery destination of the slurry liquid flowing on an upstream side of the second bifurcation part in the return line to a downstream side of the second bifurcation part in the return line.
1 . A fluid delivery apparatus configured to deliver a slurry liquid to be brought into contact with exhaust gas discharged from a combustion device to a plurality of delivery destinations, comprising:
a first delivery line for delivering the slurry liquid from a delivery source to a first delivery destination;
a return line, branching off from the first delivery line at a first bifurcation part, for returning the slurry liquid to the delivery source;
a second delivery line, branching off from the return line at a second bifurcation part, for delivering the slurry liquid to a second delivery destination different from the first delivery destination; and
a delivery destination switching device configured to able to switch a delivery destination of the slurry liquid flowing on an upstream side of the second bifurcation part in the return line to a downstream side of the second bifurcation part in the return line or to the second delivery line.
2 . The fluid delivery apparatus according to claim 1 , further comprising a washing line configured to deliver a washing liquid to the second delivery line.
3 . The fluid delivery apparatus according to claim 1 ,
wherein the second delivery line includes at least one concave portion at which a slope of the second delivery line changes from downward to upward, and
wherein the fluid delivery apparatus further comprises a drain line connecting the at least one concave portion and a portion of the second delivery destination at a height lower than the concave portion.
4 . The fluid delivery apparatus according to claim 1 ,
wherein the second delivery line has a downward slope from the second bifurcation part to the second delivery destination.
5 . The fluid delivery apparatus according to claim 1 ,
wherein the first delivery destination includes a first absorption tower, and
wherein the second delivery destination includes a second absorption tower different from the first absorption tower, or a second storage device configured to store the slurry liquid to be delivered to the second absorption tower.
6 . The fluid delivery apparatus according to claim 1 ,
wherein the first delivery destination includes a first separation device configured to separate a product produced in a first absorption tower from the slurry liquid, or a third storage device configured to store the slurry liquid to be delivered to the first separation device, and
wherein the second delivery destination includes a second separation device configured to separate a product produced in a second absorption tower different from the first absorption tower from the slurry liquid, or a fourth storage device configured to store the slurry liquid to be delivered to the second separation device.
7 . The fluid delivery apparatus according to claim 1 ,
wherein the first delivery destination includes a separation device configured to separate a product produced in an absorption tower from the slurry liquid, or a fifth storage device configured to store the slurry liquid to be delivered to the separation device, and
wherein the second delivery destination includes a sixth storage device different from the fifth storage device and configured to store the slurry liquid to be delivered to the separation device.
8 . A method for modifying a fluid delivery apparatus configured to deliver a slurry liquid to be brought into contact with exhaust gas discharged from a combustion device to at least one delivery destination,
the fluid delivery apparatus comprising:
a first delivery line for delivering the slurry liquid from a delivery source to a first delivery destination; and
a return line, branching off from the first delivery line at a first bifurcation part, for returning the slurry liquid to the delivery source,
the method comprising:
a second delivery line addition step of additionally installing a second delivery line, branching off from the return line at a second bifurcation part, for delivering the slurry liquid to a second delivery destination different from the first delivery destination; and
a delivery destination switching device addition step of additionally installing a delivery destination switching device configured to able to switch a delivery destination of the slurry liquid flowing on an upstream side of the second bifurcation part in the return line to a downstream side of the second bifurcation part in the return line or to the second delivery line.
