摘要：To address the bottleneck of efficient and low-cost CO2 capture from blast furnace flue gas, this study systematically investigates HOP gas-liquid mass transfer intensification technology. Via high-speed camera observation, laboratory experiments and Meishan hundred-cubic-meter-scale pilot, the dual-orifice jet's five-stage breakup and mass transfer mechanism are revealed, and operating parameter effects on eta and K(G)a are clarified. The bag-breakup mode generated 323 droplets, with an average particle size of 500 similar to 800 mu m. This significantly increased the contact area between the liquid and gas phases. The oscillation frequency range of the droplets was 100 similar to 1430 Hz, which enhanced the rate of interface renewal. 28 % DETA +2 % PZ performs best (eta(max) = 90.1 %, K(G)a(max) = 2.89 kmol kPa(-1)& centerdot;m(-3)& centerdot;s(-1)). An empirical formula for 28 % DETA +2 % PZ and CO2 mass transfer was proposed. The 4.2 m-tall pilot device has a carbon capture efficiency ranging 84.18 % similar to 97.48 %, and its footprint is reduced by 60 % similar to 80 %. This compact design significantly cuts down manufacturing, civil engineering and space occupation costs while ensuring operational stability, providing crucial technical support and engineering references for CO2 capture in high-carbon emission industries.
