火葬场焚化炉烟道气净化装置 摘 要 随着全球变暖、酸雨、粉尘污染、三个污染议题日益受到重视，人们环保研究开发意识的增强，环保研究开发设备市场也日益兴旺。本文主要介绍了一种新型的火葬场焚化炉烟道气净化装置，阐述了火葬场烟道气净化的必要性和及重要意义，介绍了火葬场烟道气净化系统的工作原理和流程；对现行的火葬场焚化炉烟道气处理方法作了系统的分析，从火葬场烟道气的净化方法到烟道气的净化装置都做了一个合理的设计，综合提出了一整套火葬场烟道气净化的科学合理的方案并提出了一种新型的，经济的，环保的火葬场烟道气净化方法。 对于火葬场来说，由于火化过程中产生的尾气大部分是有机物粉尘，它们在排入大气后对周围环境造成了严重的污染，针对这种情况设计出这样一套装置，首先让烟道气通过一个喷淋塔将有机物沉降，再进入环流脱水器中对湿气进行脱水干燥。沉积物多是有机物成分，先在沉淀池沉淀，然后作为原料通入沼气池制沼气，达到保护环境资源充分利用的目的。本文主要阐述了火葬场烟道气净化的必要性及其重要意义；介绍了各个方案的整体设计；重点介绍了采用侧喷淋装置吸收烟道气中的粉尘的优越性及其原理和工作流程；介绍了做为喷淋塔附属设备旋流脱水器的设计与工作原理以及沉淀池的设计与工作流程；并完成了火葬场烟道气除尘装置中沼气池部分的设计。与喷淋塔、脱硫装置和沉淀池一起组成了一套完整的火葬场烟道气除尘装置。 另外，还介绍了一次线性回归分析法，线性盈亏平衡分析的数学计算方法与图解方法：盈亏平衡Abstract Because of global warning acid pollution and farina pollution that three growing in importance, people’s awareness of environmental protection are boosting up day by day. And development of environmental protection equipment market is growing prosperity. This paper mainly introduces a new kind of incinerator exhaust purifying device in a crematorium. We systematically analised current crematorium incinerator exhaust processing methods , put forward a new kind of economical conservative approach , elaborated on the necessity and important meaning of crematorium exhaust purifying , and introduced the working principle and process of crematorium exhaust purifying system. We have made a reasonable design ranging from the crematorium exhaust purifying method to exhaust purifying device, and comprehensively put forward a set of scientific and reasonable skeme on exhaust purifying. For the cremation, because of the most of product of cremation process is the organic dust; they are discharged into the atmosphere, which causing serious pollution to the surrounding environment. To the question, we design such a device: first of all, we make the flue gas through a spray tower to subside organic farina. Second, the flue gas through the circumfluent dehydrator to dry the gas. Most sediment is organic component; the first step is to precipitate it in th
