冷凝式燃气采暖炉和燃气热水器尽可能的将排烟温度降低,同时烟气中所生成的酸性气体随之溶于冷凝水中,冷凝水呈酸性,其p H值为3左右。生成的冷凝水需要及时排出,如果不加任何中和处理而直接排出的话,会对环境造成污染,同时也会渐渐腐蚀铸铁型下水管道等。对此,应该在器具中装配有中和酸性冷凝水的中和装置,简称中和器。针对这些要求,论文介绍的了关于装配在器具里的中和冷凝水中酸性物质的中和器的一些设计要领和技巧。
The condensing gas heating furnace and the gas water heater reduce the exhaust gas temperature as much as possible, and at the same time, the acidic gas generated in the flue gas is dissolved in the condensed water, and the condensed water is acidic, and its pH value is about 3. The generated condensate needs to be discharged in a timely manner. If it is discharged without any neutralization treatment, it will cause environmental pollution, and it will also gradually erode cast iron-type sewage pipes. In this regard, a neutralizing device for neutralizing acidic condensate, referred to as a neutralizer, should be installed in the appliance. In response to these requirements, the paper introduced some of the design essentials and techniques for a neutralizer for neutralizing acid in condensing water that was installed in the appliance.
