[0013] Embodiment 1: A cooling device for a high-temperature working environment, including a jacketed tube, the diameter of which is 50 mm smaller than the inner diameter of the equipment, and the jacketed tube is composed of four equally divided arc clamps 1, the arc clamp 1 is composed of an inner plate wall 11 and an outer plate wall 12, the inner plate wall 11 and the outer plate wall 12 are connected on both sides by straight strip-type sealing plates, the top is connected by an arc-shaped sealing plate, and the bottom is connected by a fan-shaped connecting plate 13, and the center of the connecting plate 13 coincides with the center of the arc clamp 1; the inner plate wall 11, the outer plate wall 12, the sealing plate and the connecting plate 13 are all stainless steel plates with a thickness of 1 mm. A number of partitions 2 are welded radially along the arc partition inside the arc clamp 1, and water outlets are alternately opened at the top and bottom of the partition 2, and the water outlets opened at the left and right end partitions 2 are both at the bottom of the partition 2, and the partition 2 is a stainless steel bar with a thickness of 2 mm. The two ends of the sealing plate at the top of the arc clamp plate 1 are respectively provided with a water outlet pipe 3 and a water inlet pipe 4 to communicate with the inside of the arc clamp plate, and the water inlet pipe and the water outlet pipe are Φ12 steel pipes. The top and bottom of both sides of the arc clamp plate 1 are respectively welded to connect the ear pieces 5, and screw holes are opened on the ear pieces 5.

[0014] After four equally divided arc clamps 1 are put in, they are assembled into a clamping sleeve through ear pieces 5 and bolts. Cold water is injected into the arc clamps 1 from the water inlet pipe 3, and the cold water flows along the area separated by the partition and the water outlet, and finally discharged from the water outlet pipe 4. During the flow process, the heat generated during preheating is continuously absorbed, so that the temperature of the working area in the middle of the clamping sleeve is reduced from 100°C to about 30°C. Workers can work in it for 40 to 50 minutes, and safety accidents such as scalding and heat stroke caused by high temperature environment can be avoided.
