低溫余熱回收系統是怎么工作的：針對30-80℃的工業廢水，通過高效換熱器或熱泵機組提取熱能；將回收的熱能轉化為70-95℃高溫熱水，無縫對接工廠用熱需求；廢水余熱→加熱凈水→供給鍋爐/清洗/生產線→減少外部能源依賴，實現“熱-水-熱”循環。

How does the low-temperature waste heat recovery system work: for industrial wastewater at 30-80 ℃, heat energy is extracted through efficient heat exchangers or heat pump units; Convert the recovered heat energy into high temperature hot water at 70-95 ℃, seamlessly meeting the heat demand of the factory; Waste heat from wastewater → Heating purified water → Supplying boilers/cleaning/production lines → Reducing external energy dependence, achieving a "heat water heat" cycle.
