污水源热泵换热器的污染与防护研究进展

RESEARCH PROGRESS ON POLLUTION AND CONTROL OF SEWAGE SOURCE HEATPUMP HEAT EXCHANGER

污水中蕴含着丰富的热能,回收利用污水中的热能是节能领域的一个重要研究方向。污水源热泵技术是回收利用污水热能的重要技术手段,然而,污水源热泵在污水中长期运行会导致其换热器受到腐蚀结垢的影响,从而降低污水热能的转化效率和污水处理厂的资源利用率。因此,以城市污水处理厂水源热泵换热器为研究对象,深入探究影响其传热性能的关键水质因素,并综合评价其在复杂水质条件下所采取的防护措施的效果。

Sewage contains abundant heat energy.Recycling heat energy in sewage is an important research direction in the field of energy conservation.Sewage source heat pump technology is an important technical means for recycling sewage heat energy.However,the long-term operation of sewage source heat pump in sewage will cause its heat exchanger affected by corrosion and scaling,thereby reducing the conversion efficiency of sewage heat energy and the resource utilization rate of sewage treatment plants.Therefore,taking the water source heat pump heat exchanger of urban sewage treatment plant as the research object,the key water quality factors affecting its heat transfer performance are deeply explored,and the effect of protective measures taken under complex water quality conditions is comprehensively evaluated.This study provides a reference for solving the long-term pollution problems of water source heat pump heat exchanger in the sewage treatment process with high efficiency and low cost,helps achieve the goal of carbon neutralization operation of sewage treatment.
