The design of the electronic control system should have good adaptability to ensure its stable and reliable operation in low temperature, dusty and other environments. It can evenly and stably spray and blow the lime powder into the molten pool to achieve the purpose of energy saving and consumption reduction.
(1) The whole process of spraying lime powder realizes fully automatic control: the exhaust of spraying powder tank, charging, pressurizing, spraying powder and adjusting the flow of spraying powder can be controlled fully automatically;
(2) Lime powder spraying flow rate can be adjusted at the right time: the flow rate can be adjusted according to the needs of Party A, with accurate and stable adjustment, reliable work and long service life;
(3) Powder spray tank fluidization device needs to ensure that the whole process of spraying is stable and pulsation is small;
(4) The valve should ensure stable long-term work in the environment with pressure and dust.
(5) Equipped with on-site operation box, which is convenient for on-site operation.
Energy medium and lime powder conditions
(1) Lime powder warehouse fluidization, pressurization, instrumentation gas source medium
Gas source medium: argon;
Working pressure: ≥ 1.2Mpa; flow 180Nm3/h.
(2) Lime powder (for blowing): water content of lime powder ≤1% and
0-74um, 85%, 74-254um, 15%
