煤化工一体化节能技改的工程实践

为解决煤气鼓风机、循环水泵等设计余量大、能耗高的问题,开展了节能研究和改造。将煤气鼓风机液力耦合器调速系统改为高压变频调速系统,将循环水泵改为变流恒压泵,节能量可达30%以上;将循环水冷却塔风机改为水轮机驱动,可实现系统能量的二次利用。一体化节能改造项目实施后,每年可节电3 843.69×104kWh,折12 799.49 t标煤。

Revamping Practice of Integrated Energy Saving Technology of Coal Chemical Industry

Energy conservation and revamping was developed to solve the high energy consumption caused by too much design margin of the gas blower, circulating pumps, etc. Changing the speed regulating system of the hydraulic coupler into a high voltage variable frequency speed regulating system and the circulating pumps into the constant pressure variable flow pump could save over 30% energy. And changing the blower of the cooling water tower into a water turbine could achieve 100% energy conservation. After the completion of the power could be saved, and this saving equals to 12 799.49 t of integrated energy conservation revamping, 3 843.69x10^4 kWh standard coal.
