This invention relates to an apparatus and method for the efficient capture of iodine-containing exhaust gas, comprising a tower system, a gas supply system, an absorbent system, an exhaust gas detection system, and a control system. Iodine-containing exhaust gas enters from the bottom of the tower system via the gas supply system and flows upward within the tower. The absorbent system enters from the top of the tower system via a nozzle and flows downward. The two gases come into countercurrent contact within the tower. Sodium hydroxide in the absorbent reacts with iodine in the exhaust gas to form iodide, thus converting iodine from the gas phase to the liquid phase, achieving iodine absorption and capture. After absorption and capture, the exhaust gas passes through a demisting section to capture entrained droplets before being discharged from the top of the tower system. The exhaust gas detection system measures the concentration of iodine in the exhaust gas. This method enables efficient gas-liquid contact and mass transfer, and achieves constant-temperature circulation and composition control of the alkaline solution. Through optimized tower structure and control system, it achieves stable and efficient capture of iodine from iodine-containing exhaust gas, possessing good potential for scientific research verification and engineering scale-up.

This application relates to the field of suspension bridge cable strand processing technology, specifically disclosing a method for anchoring ultra-high strength cable strands. The method includes the following steps: collecting structural parameters of the anchor cup, wire separator, and wire bundle entities and constructing a digital twin model; collecting process parameters of the cable strand anchoring process and synchronously mapping them to the digital twin model; comparing the collected parameters with preset safety ranges, marking parameters that do not meet preset safety thresholds as process parameters to be adjusted; calculating the actual injection amount by collecting the alloy weight difference before and after anchoring; comparing the reverse displacement curve and injection amount of each anchor with historical qualified data intervals; if the range is exceeded, marking the anchor as a defective anchor and triggering an alarm; retrieving parameters of the defective anchor and analyzing them to obtain an optimized safety threshold range for the process parameters. The purpose of this patent is to solve the problem of lacking effective monitoring and control methods during the cable strand anchoring process, making real-time process monitoring and adjustment impossible.
