  摘要:

  以某污泥干化燃烧处置项目为研究对象，别离成立污泥干化系统、燃烧和余热操纵系统和烟气处置系统的能量均衡模子。基在现实运转数据和现场测定命据，肯定了运转时代污泥干化燃烧系统中首要的能量丧失点,包罗干化载气洗涤水热丧失、干化机散热丧失、燃烧炉和余热操纵系统散热丧失、烟气洗涤水热丧失等。针对系统首要的能量丧失点，提出了针对全进程的节能降耗方案。即，起首经由过程运转参数调理来提高干化机和燃烧和余热操纵系统效力从而削减散热丧失，再经由过程余热操纵干化载气和洗涤塔前烟气,从而削减载气洗涤排污热丧失和烟气洗涤水热丧失。

  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.
