[0025] A specific application of this embodiment is:

[0026] Water heat recovery system; The hot gas collector collects the waste heat generated during the operation of the mechanical equipment through a pipeline and introduces it into the heat exchanger. The heat exchanger is internally provided with a heat exchange medium. Through the heat exchange between the heat exchange medium and the gas, the heat energy in the gas is transferred to the heat exchange medium. The heat exchange medium carries the heat energy into the heat storage device and stores the heat energy to form hot water or steam. The heat storage device can provide hot water or steam to the heat-using equipment through a pipeline according to actual needs. The control system monitors the working states of the hot gas collector, the heat exchanger and the heat storage device in real time through sensors and adjusts their working parameters according to actual needs to ensure the stability and efficiency of the system.

[0027] Heat energy recovery system; when the mechanical equipment is running, the waste heat generated is transferred to the heat pump through the heat exchanger. After the heat pump absorbs the waste heat, it drives the refrigerant cycle, converts the waste heat into high-temperature heat energy, and stores it in the heat storage device. When heat energy is needed, the control device will automatically extract heat energy from the heat storage device to meet the production and living needs.

There is water inside the heat exchanger, and through the heat exchange between the water and the hot gas, the water evaporates to generate steam. The generated steam enters the steam generator, and after storage and regulation, it is transported to the heat-using equipment through the pipeline. The control system monitors the working states of the hot gas collector, the heat exchanger, and the steam generator in real time through sensors, and adjusts their working parameters according to actual needs to ensure the stability and high efficiency of the system.
