Abstract

The invention discloses a cooling water leakage monitoring method and device of a material cooler. The cooling water leakage monitoring method comprises the steps of arranging a resistance detection probe on an inner wall, in contact with a solid material which does not have conductivity, of the material cooler, and connecting a resistance detector by a cable; and detecting change of a resistancevalue by the resistance detector, and detecting leakage of cooling water in the material cooler in real time. According to the characteristics that the solid material does not have conductivity, the characteristics of the non-conductivity of the solid material cannot be changed after the cooling water enters the solid material and is mixed and when the cooling water in the cooler is leaked, so that the insulation resistance becomes smaller, and the leakage condition of the cooling water in the material cooler is judged according to the resistance change detected by the resistance detector. Bythe cooling water leakage monitoring method, the internal leakage of the material cooler can be monitored in real time, particularly, slight leakage of the cooler is monitored, and meanwhile, a leakage point can be effectively positioned.

Description

technical field [0001] The invention relates to a material cooler system and a material cooler leakage detection method, in particular to a material cooler cooling water leakage monitoring method and device. Background technique [0002] The material cooler is a device that cools the high-temperature material at 500-1000°C to 100-150°C. The material cooler is mostly a plate jacket or membrane wall tube structure, and cooling water is passed through the plate jacket or membrane wall tube. The high-temperature material continuously turns and rolls in the material cooler or falls at a constant speed in the cooler silo to fully contact the inner wall of the silo and then realize heat exchange through radiation, convection, conduction, etc. to reduce the temperature of the material. Since the inner and outer walls of the water-cooled wall are low-carbon steel or alloy steel welded structures, welding defects or wear during the contact process between the wall and the material hea...
