Tubular cooling device for rapidly cooling high-temperature gas

The utility model discloses a tubular cooling device for quickly cooling high-temperature gas, which comprises an air duct extending along the vertical direction, a nozzle is mounted in the air duct, at least two baffle plates staggered at intervals along the vertical direction are mounted below the nozzle, and two ends of each baffle plate form a mounting end and a water curtain end. The mounting end is fixedly mounted on the air duct, and the water curtain end inwards exceeds the central axis of the air duct; the end part of the water curtain end is bent upwards to form a water retaining part, a water curtain area is arranged at the water curtain end, water spraying holes are formed in the water curtain area, and accumulated water on the baffle plate can flow downwards through the water spraying holes to form a water curtain; the lower end of the air duct forms an air inlet, and the upper end of the air duct forms an air outlet. The water retaining part is arranged in the water curtain area of the baffle pl
