国家执行二氧化硫排放控制以来，涌现出一大批脱硫除尘技术，其中以湿法最多，很多技术方案为自激式。这一类技术专利和一些新产品，在除雾和排烟温度方面尚存在一些没解决好或未解决的问题。这里提出来以便在技术开发和鉴定中引起重视，避免物力财力的浪费。一、除雾问题... Since the implementation of sulfur dioxide emission control by the state, a large number of desulfurization and dust removal technologies have emerged. Among them, the wet method is the most used, and many technical solutions are self-excited. This type of technology patents and some new products, there are still some problems not solved or unresolved in the demisting and smoke temperature. Here to raise the technical development and appraisal in the attention, to avoid the waste of material and financial resources. First, the problem of demisting
