Integrated coal-electricity energy utilization system

The invention relates to a green-power eco-utilization system, wherein integration of coal and electricity is the core of the system and the purpose of the system is to realize whole-lifecycle high-efficiency utilization of resources. The system can recover sulphur, prevent environmental pollution and promote sound development of coal mines and environment through integrated purification and treatment of flue gas in a power plant while utilizing fire coal and drain waste water for power generation. The invention provides an integrated coal-electricity energy utilization system which comprises a coal mining plant, a thermal power plant, a flue gas desulphurization assembly and a sulphur production assembly, wherein the thermal power plant uses drain waste water and fire coal produced in the coal mining plant for power generation, the flue gas desulphurization assembly comprises an adsorption tower, an analytic tower and a first screening de-dusting device, and the sulphur production assembly comprises an eleme
