[0028] In detail, the heat storage mechanism 38 includes a heat insulation plate 381, a heat insulation plate 382, a water treatment tank 383, a water tank 384, a sealing block 385, a sealing block 386, a heat-resistant water pumping pipe 387, a water pump 388, a heat-resistant water pumping pipe 389, a water pump 3810, and an outlet pipe 3811.

The water treatment tank 383 is located at the left end of heat insulation plate 382, and the water tank 384 is located at the water treatment layer. At the top of the water treatment tank 383, sealing blocks 386 and 385 are respectively arranged in a front-to-back configuration on the top right side of the water tank 384. A heat-resistant water pump 387 is arranged around the buffer layer 332. A second water pump 388 is mounted on the first heat-resistant water pump 387, and a second heat-resistant water pump 389 is also arranged around the buffer layer 332. A third water pump 3810 is mounted on the second heat-resistant water pump 389. An outlet pipe 3811 is located at the left end of the water treatment tank 383 and extends outward through the heat storage tank 32. A water-saving mechanism 3 is installed next to the water mist cooling device 1. Wastewater is introduced into the filter box 34 by the first water pump 36 for filtration, and then, after absorbing heat through the surrounding buffer layer 332, it is stored in the water tank 384 until the internal temperature reaches 100 degrees Celsius. At this point, the water is guided to the bathhouse through the outlet pipe 3811, saving electricity and significantly improving resource utilization. The residue filtered through filter box 34 will be disposed of in a unified manner to avoid impacting the external environment.
[0029] Both sealing block 1 (385) and sealing block 2 (386) are rectangular in shape. Heat-resistant water pumping pipe 1 (387) and heat-resistant water pumping pipe 2 (389) are intertwined and wrapped around each other on the buffer layer 332. The water pumping end of heat-resistant water pumping pipe 1 (387) passes through the side wall of heat insulation plate 1 (381) and filter box 34 and is located inside the filter box 34.

[0030] A temperature sensing component 3831 is installed at the front end of the internal connection of the water treatment tank 383, which monitors the water inside the water tank 384.
[0031] Working principle: The high-temperature stainless steel pipe first passes through the pipe groove 33 and then continues to the water mist cooling device 1 for cooling. The aluminum silicate fiber reinforced plate 331 can effectively collect and absorb heat. Then, through the temperature control of the buffer layer 332, the surface of the buffer layer 332 reaches the temperature that the heat-resistant water pumping pipe can withstand. The wastewater after cooling the high-temperature stainless steel pipe by the water mist cooling device 1 is drawn by water pump 36 and enters the filter box 34 through the inlet pipe 35. After being filtered by the filter assembly 37, the filtered water is drawn by water pump 388 and flows along... The water is collected in the water tank 384 through the heat-resistant water pipe 387 after passing through the buffer layer 332 multiple times. The temperature sensing component 3831 continuously monitors the temperature. If the temperature does not reach 100 degrees Celsius, the water inside the water tank 384 will be drawn by the water pump 3810 through the water treatment tank 383 and flow through the heat-resistant water pipe 389, passing through the buffer layer 332 multiple times before returning to the water tank 384. The process continues until the temperature sensing component 3831 detects that the water temperature in the water tank 384 has reached 100 degrees Celsius. Then, the water is released into the bathhouse through the outlet pipe 3811 via the water treatment tank 383.

These components are all general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. The problem solved by this utility model is that existing water mist cooling devices in annealing furnaces used for stainless steel pipe production cannot effectively collect or recycle the wastewater after cooling the high-temperature stainless steel pipes.
