Daily usage and ratio of coal water slurry additives

Thread Content

The daily consumption of water-coal slurry additives is about 7.5 tons, equivalent to 300 bags, and they are prepared in underground tanks. 1. After adding the additives prepared in the underground tank to the additive tank (V-1202), measure the liquid level in the underground tank with a ruler; it should be around 0.3 meters. 2. Add water to the underground tank, keeping the liquid level at 1.3 meters; the amount of water required is approximately 10 m3 (10 tons of water). 3. Add 75 bags of water-coal slurry additive to the underground tank, and start the mixer (M-1204) at the same time. 4. Add the water-coal slurry additive and, after mixing evenly, stop the mixer (M-1204), and notify the analysis team to test the concentration of the additive in the underground tank (the concentration is approximately 17%). 5. After the analysis is satisfactory, start the pump (P-1203) to add the prepared additive to the additive tank (V-1202) for use in pulp production. 6. Stop the pump (P-1203) when the liquid level of the additive in the underground tank is around 0.3 meters, and continue preparing the additive. Note: Additives are prepared during the day shift; before the end of the shift, it is necessary to ensure that the liquid level in the additive tank (V-1202) remains above 3 meters. One additional tank is prepared for use underground, and no additives are prepared during the night shift.
