生活垃圾焚烧发电厂防臭控制分析

Analysis on Deodorization Control of Municipal Solid Waste Incineration Power Plant

随着人们的日常生活垃圾不断的增加,垃圾处理工作逐步增大,据国内运行情况表明,能够达到标准的生活垃圾可以通过电厂焚烧进行再利用,同时减少了生活垃圾的存放量也是促进发电行业迅速发展的条件之一。由于生活垃圾中包含的成分相对比较复杂,在运输到垃圾池内存储和焚烧过程当中,防止恶臭散发也是尤为重要的,这主要是因为恶臭是通过空气作为介质传输,并且速度非常快,人们长时间接触会引起情绪烦躁同时也损害工作人员的身体健康,也对环境造成二次污染,并且在焚烧生活垃圾过程中产生的污染物伤害远远超过正常燃烧煤炭所产生污染物。例如,在生活垃圾存储发酵过程产生的甲烷和硫化氢等气体及圾焚烧过程中产生的二噁英等有害气体,没有进行合理的处理措施,则将影响工作人员身体健康、周围居民的生活及造成环境的污染。此文针对生活垃圾焚烧发电过程中出现的恶臭及有害物质、气体的控制及防范措施的分析。现根据安徽某生活垃圾焚烧发电厂施工经验做如下分析。

With the continuous increase of people's daily domestic waste,the garbage disposal work is gradually increasing.According to the domestic operation situation,the municipal solid waste that can meet the standard can be reused through power plant incineration.At the same time,reducing the storage of domestic waste is also one of the conditions to promote the rapid development of power generation industry.Because the components contained in domestic waste are relatively complex,it is also particularly important to prevent the emission of stench in the process of being transported to garbage ponds for storage and incineration,mainly because the stench is transmitted through air as a medium.And the speed is very fast,people contact for a long time can cause emotional irritability and damage workers at the same time.The health of the staff also causes secondary pollution to the environment,and the pollutants caused by the incineration of domestic waste far outweigh the pollutants caused by the normal combustion of coal.For example,gases such as methane and hydrogen sulfide produced during municipal solid waste storage and fermentation and harmful gases such as dioxins produced during garbage incineration,without reasonable treatment measures,will affect the health of the staff,The life of the surrounding residents and the pollution of the environment.This paper mainly analyzes the odor and harmful substances,gas control and preventive measures in the process of MSW incineration and power generation.According to the construction experience of a domestic waste incineration power plant in Anhui Province,the following analysis is made.
