The utility model discloses a novel dry-process cement production line residual heat generation system, which includes a grog cooler, an AQC residual heat boiler, a cement rotary kiln, a cement rotary kiln head cover, a three-time wind blast pipe, a cement preheat machine, a cement pre-reduction furnace, a SP residual heat boiler, an air blower, a deaerator, and a condenser as well as a steam turbine generating set; wherein, the three-time blast pipe is positioned between the cement rotary kiln head cover and the cement pre-reduction furnace; while the cement rotary kiln head cover is communicated with the grog cooler. The utility model is characterized in that the pipeline of the three-time blast pipe is provided with a three-time wind residual heat boiler with a bypass wind tunnel, the working fluid entrance end of the three-time wind residual heat boiler is connected with the AQC residual heat boiler and the SP residual heat boiler through pipelines; while the working fluid entrance end is connected with the steam turbine generating unit and can fully dip out the process residual heat of the production line, so as to provide the overheat steam meeting the generation of the steam turbine generating set; and the cement ton grog generating volume is more than 40kwh, thus the utility model is easy to be implemented.
