洗浴污水余热耦合空气源回收系统优化研究OA

To address issues such as high energy consumption and serious waste of residual heat in coal mine bathing systems,this paper optimizes a system for recovering heat from air-source energy coupled with residual heat from bathing wastewater.The system indirectly extracts low-temperature heat from bathing wastewater through a wastewater-source heat pump and uses an air-source heat pump as an auxiliary heat source,employing a circulation heating method to ensure stable water temperature in the bath.In addition,the paper details the composition of the system,the basis for selecting heat sources,methods for load calculation,and approaches for equipment selection,and vali-dates the system through actual engineering case studies.The results show that,compared with traditional coal-fired boilers,the system can save 328.13 tons of standard coal annually,it significantly reduces the emissions of pollu-tants such as carbon dioxide and nitrogen oxides.It has notable environmental benefits and application value,provi-ding a practical technical solution for the low-carbon transformation of bathing systems in industrial and mining enter-prises.
