Description

Technical Field

[0002] The steam-water heat exchanger is a heat exchange device used to recover waste heat and convert it into useful energy. It achieves heat transfer and energy recovery by contacting high-temperature or hot steam with low-temperature water or air. Its operating principle is based on the second law of thermodynamics, that is, heat will spontaneously flow from the high-temperature area to the low-temperature area. This process is mainly achieved in two ways: convection and conduction. In the steam-water heat exchanger, hot steam flows from the high-temperature area through the heat exchanger. In this process, the heat is transferred to the low-temperature water or air and cooled down. In this way, the waste heat is recovered so that it can be reused, but the current energy-saving steam-water heat exchanger does not have a water purification function, resulting in poor water quality, requiring frequent maintenance and cleaning of the equipment, increasing maintenance costs, and does not have a flocculant delivery function, resulting in the need for manual delivery, which is very troublesome. For this reason, we propose an energy-saving steam-water heat exchanger. Utility Model Content
