In the flue gas desulfurization project of the power plant, limestone is used as an adsorbent, which is crushed into powder and transported to the slurry tank for mixing with water. The limestone slurry is fully and evenly stirred by the stirrer. After reaching the specified concentration, it is transported to the absorption tower and discharged into the tower. The flue gas in the flue gas is fully contacted and mixed. The sulfur dioxide in the flue gas is oxidized in the slurry and the air blown from the lower part of the absorption tower to produce. After reaching a certain saturation, it crystallizes into dihydrate gypsum. The discharge pump discharges the gypsum to the dehydration system. After secondary filtration by the vacuum belt filter, when the moisture content reaches less than %, it is transported to the gypsum storage by transportation machinery. Part of the slurry separated from the gypsum slurry is treated by the wastewater treatment system and discharged after reaching the standard. If the power plant needs to shut down the limestone slurry tank desulfurization mixing device for a long time, the following matters should be paid attention to
. If the system needs to be overhauled and the mixing device shut down, all equipment in each system must be shut down, and the slurry in the tank and box must be removed. It is stored in the accident propeller tank. At this time, only the pit mixer is put into use.
.During the shutdown of the limestone slurry desulfurization mixing device, in order to prevent the limestone slurry from settling, the limestone slurry tank must be drained before stopping the limestone liquid pump and limestone slurry tank.
. Before the limestone slurry tank desulfurization mixing device is shut down, try to reduce the limestone unloading hopper material level and the limestone storage bin material level as much as possible, and use up the limestone during the shutdown. For example, the limestone storage bin is in a state of storing limestone. During shutdown, the manual gate valve under the limestone storage silo should be closed to prevent limestone from clogging in the limestone storage silo.
.When it is necessary to repair the limestone slurry tank or mixer, the liquid level and slurry concentration should be reduced as much as possible during operation, and the remaining slurry should be drained into the ditch as much as possible after shutdown.
