Title:
BLAST FURNACE GAS RECYCLING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/033056
Kind Code:
A1
Abstract:
A blast furnace gas recycling system, comprising a dry-type bag-type dust collecting device (1), an organic Rankine cycle power generation device (2), a multistage compressor device (3) and a fuel gas-steam combined cycle power generation device (4). The organic Rankine cycle power generation device (2) comprises an evaporator (21), an expansion turbine (22) and an electric generator (23). A working medium inlet of the evaporator (21) is in communication with a working medium outlet of the expansion turbine (22) via a pipeline, a working medium outlet of the evaporator (21) is in communication with a working medium inlet of the expansion turbine machine (22) via a pipeline, and the electric generator (23) is connected to an output end of the expansion turbine (22). The dry-type bag-type dust collecting device (1), the evaporator (21), the multistage compressor device (3) and the fuel gas-steam combined cycle power generation device (4) are sequentially connected via pipelines. The blast furnace gas recycling system makes full use of the temperature and pressure of the blast furnace gas, and improves the recycling efficiency of the blast furnace gas.
