[0020] Embodiment: It includes an exhaust furnace body 1, and a spraying device 2 is provided in the middle of the inner wall of the exhaust furnace body 1. The spraying device 2 can spray the inside of the exhaust furnace body 1 to cool it down. A water supply valve 3 is fixedly connected to the lower end of the spraying device 2. The water supply valve 3 can supply water to the spraying device 2 and adjust the amount of water supplied. A rotating ring 4 is provided at the upper end of the inner wall of the exhaust furnace body 1, and an adjusting mechanism 5 is rotatably connected to the rotating ring 4. The adjusting mechanism 5 is connected to the water supply valve 3. The adjusting mechanism 5 can adjust the opening and closing of the water supply valve 3. A water supply pipe 6 is fixedly connected to the lower surface of the water supply valve 3.

[0021] The adjustment mechanism 5 includes a mounting ring 7, the outer side of which is provided with a groove, which is adapted to the rotating ring 4, and support rollers 8 are installed on both the upper and lower sides of the rotating ring 4, and the support rollers 8 are in contact with the inner wall of the groove. When the mounting ring 7 rotates, the support rollers 8 can reduce the friction between the mounting ring 7 and the rotating ring 4. A deflection blade 9 is fixedly connected to the inner side of the mounting ring 7. A limit ring 10 is fixedly connected to the inner side of the deflection blade 9, and a speed regulating mechanism 11 is fixedly connected to the interior of the limit ring 10. When the smoke flows through the deflection blade 9, it can push the mounting ring 7 to rotate.

[0022] The speed regulating mechanism 11 includes a connecting rod 12, which is arranged inside the limiting ring 10. The middle of the connecting rod 12 is fixedly connected to a support platform 13, the upper surface of the support platform 13 is fixedly connected to a vertical rod 14, the upper end of the vertical rod 14 is fixedly connected to a T-shaped frame 15, both ends of the T-shaped frame 15 are rotatably connected to a swing rod 16, the end of the swing rod 16 is fixedly connected to a counterweight ball 17, the middle of the swing rod 16 is rotatably connected to a linkage rod 18, and the lower end of the linkage rod 18 is fixedly connected to a connecting ring 19. When the T-shaped frame 15 rotates rapidly, it can drive the counterweight ball 17 to swing upward. When the rotation speed of the T-shaped frame 15 decreases, the counterweight ball 17 will move downward.

[0023] The inside of the connecting ring is rotatably connected with a linkage ring 20, and the lower surface of the linkage ring 20 is fixedly connected with a pull rope 21, and the lower end of the pull rope 21 is connected to the regulating switch of the water supply valve 3. When the pull rope 21 pulls the regulating switch upward, the flow of the water supply valve 3 can be increased, and the water spraying and cooling of the spraying device can be accelerated.

When the amount of smoke increases, the spraying amount of the spraying device 2 can be increased, and when the amount of smoke decreases, the spraying amount of the spraying device can be reduced. When the amount of smoke increases, the smoke will push the deflection fan blade 9, so that the rotation speed of the mounting ring 7 increases. When the rotation speed of the mounting ring 7 increases, it drives the T-shaped frame 15 to rotate.

The pull rope 21 connected by rotation in the connecting ring 19 can pull the regulating switch of the water supply valve 3, so that the flow of the water supply valve 3 increases, and then the flow of the upper spraying device 2 increases, so as to achieve better cooling. When the amount of smoke decreases, the rotation speed of the mounting ring 7 decreases, so that the switch of the water supply valve 3 automatically returns to close, reducing the flow rate of the spraying system.
