摘要:- 以某污泥干化焚燒處理工程為研究對象，分別建立污泥干化系統(tǒng)、焚燒及余熱利用系統(tǒng)和煙氣處理系統(tǒng)的能量平衡模型。基于實際運行數(shù)據(jù)和現(xiàn)場測定數(shù)據(jù)，確定了運行期間污泥干化焚燒系統(tǒng)中主要的能量損失點,包括干化載氣洗滌水熱損失、干化機散熱損失、焚燒爐及余熱利用系統(tǒng)散熱損失、煙氣洗滌水熱損失等。針對系統(tǒng)主要的能量損失點，提出了針對全過程的節(jié)能降耗方案。即，首先通過運行參數(shù)調(diào)節(jié)來提高干化機和焚燒及余熱利用系統(tǒng)效率從而減少散熱損失，再通過余熱利用干化載氣以及洗滌塔前煙氣,從而減少載氣洗滌排污熱損失和煙氣洗滌水熱損失。
Abstract:- Energy balance models of sludge drying system, incineration and waste heat utilization system and flue gas treatment system were established based on a sludge drying and incineration project. According to the operation data and on-site analytic data, the main energy loss points in the system were determined including the heat loss of the carrier gas washing water of drying system, the heat loss of the drying machine due to radiation, the heat loss of the incinerator and the waste heat utilization system due to radiation, and the sensible heat loss of the washing water of flue gas. According to these main energy loss points, this paper proposed an energy saving and consumption reducing scheme for the whole process. Firstly, the operating parameters are adjusted to improve the efficiency of drying machine, incineration and waste heat utilization system to reduce the heat loss. Then, through the usage of waste heat, drying carrier gas and flue gas in front of scrubbing tower, the heat loss of carrier gas washing sewage and the flue gas washing water can be reduced.
