[0062] In this embodiment, a pressure gauge 13 is installed at the liquid outlet of the fifth heating housing 205. The pressure gauge 13 is connected to the controller and is used to detect the internal pressure of the housing.

[0067] In this embodiment, the heating element is a heating tube. Electric heating wires or other heating elements can also be used according to needs, as long as the liquid can be heated.

[0068] When the utility model is in use:

[0069] 1. The liquid to be heated enters from the inlet flange 701 and then flows through the first heating housing 201, the outlet of the first heating housing 201, the first housing connecting pipe 501, the inlet of the second heating housing 202, the second heating housing 202, the outlet of the second heating housing 202, the second housing connecting pipe 502, the inlet of the third heating housing 203, the third heating housing 203, the outlet of the third heating housing 203, the third housing connecting pipe 503, the inlet of the fourth heating housing 204, the fourth heating housing 204, the outlet of the fourth heating housing 204, the fourth housing connecting pipe 504, the inlet of the fifth heating housing 205, and flows out from the outlet flange 702.

[0070] 2. During the liquid heating process, the outlet temperature sensor on each heating component detects the liquid temperature. When the temperature detected by the first outlet temperature sensor 901 is lower than the set value, the controller controls the second heating tube 102 to increase the operating power to raise the temperature of the liquid flowing through the inside of the second heating housing 202. When the temperature detected by the first outlet temperature sensor 901 is higher than the set value, the controller controls the second heating tube 102 to reduce the power to cool the liquid flowing through the inside of the second heating housing 202. And so on. The controller adjusts the operating power of the corresponding heating tube according to the signals fed back by each outlet temperature sensor to ensure precise control of the temperature of the liquid flowing out from the outlet flange 702.

[0071] 3. The end temperature sensor on each heating component detects the temperature of the corresponding heating tube and feeds it back to the controller. When the temperature of the heating tube is abnormal, the controller can control the heating tube to stop heating.

[0072] 4. When the pressure detected by the pressure gauge 13 is abnormal, the controller controls the heating tube to stop working to prevent the risk of explosion due to excessive pressure. When the liquid level sensor 11 detects a low liquid level, the controller controls the heating tube to stop working to prevent dry burning.

[0073] 5. When there is a liquid leakage situation, the liquid drips into the liquid receiving tray and contacts the liquid leakage sensor. The controller controls the heating tube to stop working according to the signal fed back by the liquid leakage sensor, and opens the drain valve 16 to drain the liquid in the heating housing for maintenance of the heating device.
