The invention discloses a thermal power plant steam turbine waste heat utilization system. The thermal power plant steam turbine waste heat utilization system comprises a filter system, a primary heatabsorption system, a flow separating system and a secondary heat absorption system. The filter system, the primary heat absorption system, the flow separating system and the secondary heat absorptionsystem are sequentially connected through pipelines. The filter system is connected with an exhaust port of a steam turbine, and impurities in steam are filtered out through the filter system. Heat in the steam is absorbed through the primary heat absorption system. Flow separating is conducted on the steam through the flow separating system, and the heat in the steam can be absorbed through thesecondary heat absorption system conveniently. The residual heat in the steam is absorbed through the secondary heat absorption system. According to the thermal power plant steam turbine waste heat utilization system, the impur
