Title:
FLUIDIZED POWDER FEEDING SYSTEM AND METHOD BASED ON WASTE GAS AND RESIDUE-QUENCHED STEEL SLAG
Document Type and Number:
WIPO Patent Application WO/2024/060402
Kind Code:
A1
Abstract:
Provided are a fluidized powder feeding system and method based on waste gas and residue-quenched steel slag, relating to the technical field of workshop conveyor systems and pneumatic pipe conveying. A first waste gas pipeline is used for receiving pressurized CO2-rich waste gas, and is communicated with an upper discharging bin (10) by means of a fluidized air pipeline, a pressurized air pipeline, and a supplementary air pipeline; a second waste gas pipeline is used for receiving the pressurized CO2-rich waste gas and is communicated with a gas-gas mixer (3); a first end of a dense-phase discharging guide pipe (9) is used for extending into the upper discharging bin (10) to receive a CO2-rich waste gas high-pressure dense-phase gas-powder flow, and a second end of the dense-phase discharging guide pipe (9) is communicated with the gas-gas mixer (3); and a discharging end of a double-helix variable-pitch sealed conveyor (7) extends into the internal space of the upper discharging bin (10), and the discharging end of the double-helix variable-pitch sealed conveyor (7) is provided with an upwardly-inclined anti-gas-cross section. The operation consumption of a cold source is reduced, and a quenched slag product having higher quality and higher activity is produced while the granularity of quenched slag products is reduced.
