Later in the working process, the temperature sensor 621 inside the dust duct 2 will monitor the temperature in the duct in real time. When the temperature exceeds a preset threshold, the sensor will transmit a signal to the control end, and the control end will send a signal to the first solenoid valve 623 to open. At this time, the cold water in the water tank 61 will be transported to the spiral coil 624 along the first connecting pipe 622, thereby performing heat exchange and cooling operations on the high temperature in the pipeline. The personnel can connect the other end of the spiral coil 624 to the work place where hot water is needed, so as to achieve heat energy conversion and avoid energy loss. Secondly, when the water level in the water tank 61 is lower than the liquid level sensor 631, its sensor signal goes directly to the control end, and the control end will control the second solenoid valve 633 to open. Since the end of the third connecting pipe 634 is connected to the water inlet source end, after the second solenoid valve 633 is opened, its cold water source will enter the water tank 61 along the third connecting pipe 634 and the second connecting pipe 632 for replenishment, which is portable and efficient.
