摘要:- 結(jié)合石洞口污泥處理二期工程的鼓泡流化床焚燒爐工藝設(shè)計(jì)以及調(diào)試情況，通過(guò)研究不同工況下半干污泥的焚燒特性，獲得焚燒過(guò)程
中產(chǎn)生的煙氣污染物NOx、SO2、CO的排放數(shù)據(jù)，分析了一次風(fēng)量、污泥給料量和污泥含水率對(duì)煙氣污染物排放特性的影響，并對(duì)焚燒爐性能考核期間CEMS在線檢測(cè)系統(tǒng)檢測(cè)到的各煙氣污染物指標(biāo)與《生活垃圾焚燒大氣污染物排放標(biāo)準(zhǔn)》（DB 31/768—2013）進(jìn)行比較，結(jié)果顯示，煙氣污染物全部達(dá)標(biāo)。同時(shí)，通過(guò)研究污泥焚燒工藝的運(yùn)行特性和煙氣污染物排放特性，給出了污泥焚燒爐燃燒工況控制的建議。
Abstract:- The design and debugging of a bubbling fluidized bed incinerator in Shidongkou sludge treatment phase Ⅱ project were analyzed. The incineration characteristics of semi-dry sludge under different working conditions were investigated, and the emission data of pollutants such as NOx, SO2 and CO in the flue gas produced in the incineration process were obtained. The influence of primary air volume, sludge feed volume and sludge moisture content on emission characteristics of the pollutants in the flue gas was analyzed. The pollutants indicators of flue gas detected by CEMS online detection system during the performance evaluation period were compared with those specified in Emission Standard of Air Pollutants for Municipal Solid Waste Incineration (DB 31/768-2013), and the results showed that all the pollutants in the flue gas conformed to the requirements of the standard. Based on the operation characteristics of the sludge incineration process and the emission characteristics of the pollutants in the flue gas, the suggestions on control of combustion condition in sludge incinerators was given.
