[0023] Before using the utility model, the air inlet pipe 1 is first connected to the air outlet pipe of the device that needs to treat water vapor (such as an existing activated carbon box); cooling water is continuously introduced into the liquid inlet pipe 6 of the heat exchanger 3. The gas that needs to treat water vapor enters the heat exchange tube 4 of the heat exchanger 3 from the air inlet pipe 1, and is converted from gaseous water vapor into liquid condensed water when it is cooled, and adheres to the inner wall of the heat exchange tube 4. Under the action of gravity, it flows into the guide groove 8 at the bottom of the heat exchange tube 4. Under the guidance of the inclined guide groove 8, the condensed water flows into the U-shaped tube 9 and accumulates at the bottom of the U-shaped tube 9. The valve 11 is opened, and the condensed water flows out from the water outlet pipe 10. After flowing out, the valve 11 is closed. At the same time, the gas that has been degassed and cooled passes through the U-shaped tube 9 and is discharged from the exhaust pipe 2. The utility model effectively utilizes the thermal energy of water vapor in high-temperature exhaust gas, which is energy-saving and environmentally friendly.

[0024] In order to make the condensed water flow smoothly from the heat exchange tube 4 to the bottom of the U-shaped tube 9, Figure 2 , Figure 4 , Figure 5 As shown, a guide rod 12 is preferably provided in the left side of the U-shaped tube 9 of the utility model, the upper end of the guide rod 12 is connected to the water outlet end of the guide groove 8, the lower end of the guide rod 12 is connected to the bottom of the U-shaped tube 9, and the rod body of the guide rod 12 does not contact the inner wall of the U-shaped tube 9. The condensed water flowing out of the guide groove 8 flows downward along the guide rod 12 to the bottom of the U-shaped tube 9.

[0025] In order to ensure that the condensed water continues to accumulate at the bottom of the U-shaped tube 9 and the gas passes through the U-shaped tube 9 smoothly, Figure 2 , Figure 4 As shown, the bottom of the U-shaped tube 9 of the utility model is preferably provided with a water storage chamber 13, and the water storage chamber 13 is connected to a water outlet pipe 10. When the condensed water accumulates to a certain amount in the water storage chamber 13, the valve 11 is opened and the condensed water flows out from the water outlet pipe 10.

[0026] In order to make the condensed water flow out from the water outlet pipe 10 smoothly, Figure 4 As shown, the bottom of the water storage chamber 13 is preferably inclined, and the lowest point thereof is connected to a water outlet pipe 10 .

[0027] In order to further improve the heat transfer effect of the heat exchanger 3, Figure 1 , Figure 3 As shown, the heat exchanger 3 is preferably provided with a heat exchange metal mesh 14, which is arranged between the heat exchange box 5 and the heat exchange tube 4, and the heat exchange metal mesh 14 is connected to the outer wall of the heat exchange tube 4, thereby increasing the heat exchange area.

[0029] When the condensed water in the water storage chamber 13 reaches the preset maximum liquid level, the liquid level sensor 15 transmits the sensing signal to the intelligent control device 16 through the control circuit. After receiving the sensing signal, the intelligent control device 16 sends a command to the valve 11 through the control circuit. After receiving the command, the valve 11 opens, and the condensed water flows out from the outlet pipe 10, and the water level of the condensed water in the water storage chamber 13 drops. When the condensed water in the water storage chamber 13 drops to the preset minimum liquid level, the liquid level sensor 15 transmits the sensing signal to the intelligent control device 16 through the control circuit. After receiving the sensing signal, the intelligent control device 16 sends a command to the valve 11 through the control circuit. After receiving the command, the valve 11 closes.
