CO₂ ABSORBENT SPRAY NOZZLE AND SPRAY TOWER TYPE CO₂ ABSORPTION DEVICE COMPRISING SAME

摘要

Disclosed are a CO₂ absorbent spray nozzle and a spray tower type CO₂ absorption device comprising the same. A CO₂ absorbent spray nozzle according to an aspect of the present invention comprises: a nozzle body having a cylindrical structure in which a single CO2 absorbent supply pipe is connected to the upper portion thereof, an absorbent receiving part having a predetermined volume is formed inside thereof, and an opening is formed in the lower portion thereof; and a nozzle plate installed in the lower opening of the nozzle body and having a plurality of nozzle holes, the sizes of which are the same over the entire nozzle plate or are different in each area of the nozzle plate, wherein a pressure pipe is connected to the upper portion of the nozzle body on the other side thereof, and under the control of a pressure regulator connected to the pressure pipe, a CO2 absorbent filled to a predetermined height in the receiving part is sprayed into a CO2 capturing reactor through the nozzle holes, such that the CO2 absorbent is uniformly distributed in the form of atomized droplets in the reactor.
