Double-source double-backpressure multi-net residual and waste heat energy heating supply system of power plant

The invention discloses a double-source double-backpressure multi-net residual and waste heat energy heating supply system. The system comprises a peak-shaving steam boiler and a backpressure device thereof and also comprises a power plant backpressure device. The system is characterized in that a shunting type steam heating device, a whole year heat using system, a peak-shaving steam boiler room, a steam heat pump device, an electric heating source device, a low-temperature heat using area, an off-net heat using system and various residual and waste heat energy gathering devices are arranged between the two backpressure devices in a communicating mode in sequence. Full capacity operation of a large amount of power plant backpressure in an area is achieved, residual and waste heat energy in the area is fully utilized, and huge energy-saving and economic benefits are achieved. 本发明种双源双背压多网余废热能供热系统，包括：调峰蒸汽锅炉及其背压装置，电厂背压装置，其特征在于：所述的两背压装置间，依次连通分流式蒸汽加热装置，常年用热系统调峰蒸汽锅炉房，蒸汽热泵装置，电热原装置，低温用热区，网外用热系统，各种余废热能汇集装置。它使区域内电厂大量背压
