At the same time, the water temperature can be sensed by the temperature sensor 104 and the control panel 101, and the equipment is automatically controlled when the water temperature reaches the set temperature.

[0028] Second embodiment

[0029] like Figures 1 to 3 As shown, the liquid inlet structure of the liquid inlet assembly 2 includes a sealing ring 203 installed on the outer surface of the first hydraulic rod 202, the bottom end of the telescopic end of the first hydraulic rod 202 is fixedly connected to the first piston plate 204, and a water inlet 205 is provided on the left side of the liquid inlet cylinder 201.

The bottom end of the liquid inlet cylinder 201 passes through the partition 105, and the top of the liquid outlet cylinder 301 passes through the partition 105.

[0030] In order to be able to drain water into different cavities, such as Figure 1 、 Figure 2 and Figure 4As shown, the liquid outlet component 3 includes a top plate 303 installed at the telescopic end of the second hydraulic rod 302, a liquid outlet 304 is provided on the left side of the liquid outlet cylinder 301, and a push rod 305 is fixedly connected to the upper surface of the top plate 303, and the top end of the push rod 305 is fixedly connected to the second piston plate 306.

Then the water enters the water tank 401, and the water enters the heat exchange tube 402 inside the water tank 401, so that the heat exchange tube 402 exchanges heat with the flue gas, and the waste heat of the flue gas is utilized to increase the water temperature. The water is discharged into the liquid outlet cylinder 301 through the outlet pipe 403, so that the water forms a cycle. After the water temperature rises, the water is sensed by the temperature sensor 104, and when the temperature reaches the set value, the control panel 101 is coordinated to start the first hydraulic rod 202 and The second hydraulic rod 302 works, thereby moving the first piston plate 204 to below the elbow 206, and the second piston plate 306 moves downward to below the water outlet pipe 403, so that the elbow 206 extracts the water above the partition 105, and discharges the water inside the heat exchange tube 402 to above the partition 105, sealing the bottom of the partition 105, and then draining the hot water through the drain pipe 102 and the first solenoid valve 103, replacing the water below the partition 105. By repeating the above operation, the water above and below the partition 105 can be quickly replaced in rotation, thereby ensuring the cooling effect on the flue gas.
