SYSTEM AND METHOD TO PREVENT THE IMPINGEMENT OF MARINE ORGANISMS AT THE INTAKE OF POWER PLANTS

摘要

Provided are a system and method for preventing the inflow of marine organisms into seawater intakes of power stations. The system includes a marine organism lifting apparatus for lifting the marine organisms and a marine organism discharging apparatus. The marine organism lifting apparatus includes a plurality of brush traveling screens installed at an inclination of a predetermined angle with respect to the seawater intakes to wholly or partially screen the seawater intakes and engaged in upper and lower sprocket wheels so that the widths of the brush traveling screens are matched to those of the seawater intakes, each brush traveling screen including a caterpillar traveling chain guided by an upper chain guiding rail and a plurality of brushes installed at the caterpillar traveling chain to lift marine organisms jammed or laid between the brushes; and a scraper installed at the upper sprocket wheel and formed with a plurality of grooves and blades to scrape the marine organisms jammed or laid between the brushes. The marine organism discharging apparatus includes a conveyor for moving the marine organisms scraped by the scraper using a screw; and a collecting box for collecting the marine organisms moved by the conveyor. Therefore, lifting of various types of marine organisms is easy, a remarkably increased treatment capacity ensures complete removal of large quantities of marine organisms, a pressure drop of seawater can be minimized, and system optimization is possible.
