Technical Field
The utility model relates to a flue gas desulfurization equipment technical field especially relates to a novel flue gas desulfurization stiff ware device.
Background
The thickener is a settler used for concentrating solid particles in suspension; the thickener is designed into a multi-layer type for certain requirements, and is mostly a cylinder with a conical bottom, suspension liquid flows in from a central liquid feeding groove, clear liquid overflows from the periphery and is discharged through an outflow groove, and the harrow moving slowly is arranged in the thickener, so that sediment or sediment is collected to the center of the bottom of the thickener and is discharged through a discharge conduit after being collected.
The existing flue gas desulfurization ammonium sulfate production device has the advantages that the temperature of a thickener in summer is high, the density of ammonium sulfate liquid is high, the solubility is high, particles on the lower part of the thickener are small, a rotary drum is blocked during discharging of a centrifugal machine, a material layer is stacked, the yield of ammonium sulfate is low, the blockage phenomenon of a flue gas desulfurization system is caused, and the flue gas desulfurization system cannot normally run.
Therefore, a novel flue gas desulfurization thickener device is provided to solve the problems.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problems of tower blockage and low ammonium sulfate yield of the thickener in the prior art, and providing a novel flue gas desulfurization thickener device.
