Abstract
The invention discloses a rotary cement kiln grate cooler novel waste heat power generation system. On the basis that a grate cooler high-quality cement production process is guaranteed, grate cooler waste heat is used for power generation. The rotary cement kiln grate cooler novel waste heat power generation system comprises a rotary kiln and a grate cooler arranged at the end of the rotary cement kiln. A high-temperature section, a medium-temperature section and a low-temperature section are arranged on the grate cooler in the direction far away from the rotary kiln in sequence. A circulating water bag is wrapped on the outer surface of the low-temperature section. The circulating water bag is filled with water. Water is injected into the circulating water bag through a water supplement tank, meanwhile, the circulating water bag conveys high-temperature water which absorbs heat into a boiler through a pipeline, and the boiler conveys hot steam into a turbine generator for power generation. A heat-preservation layer is wrapped on the outer surface of the high-temperature section. The hot steam passes through the turbine generator and then is fed into a cooling spraying tower for cooling, and liquid-state water is fed into the circulating water bag after cooling.
