Converter dry dedusting evaporative cooler scaling matter impact prevention device

The utility model relates to a scaling matter impact prevention device for a converter dry dedusting evaporative cooler. The scaling matter impact prevention device is installed in a banana bend below a smoke outlet of the evaporative cooler. The anti-collision beams are transversely arranged at intervals along the smoke outlet, the two ends of each anti-collision beam are fixedly connected with the side wall of the upper portion of the banana bend, and a crushing ridge is arranged at the top of each anti-collision beam; the distance between the anti-collision beams is smaller than the width of the coarse ash discharging opening. The device not only can effectively prevent scaling substances on the inner wall of the evaporative cooler from falling off to block a coarse ash conveying mechanism below, but also can effectively prevent the scaling substances from falling off to impact and damage built-in chain type ash conveying machine equipment, is simple in structure, convenient to operate and easy to implemen
