The invention relates to the technical field of flue gas treatment equipment, and discloses a fluidized tank for a flue gas treatment process, which includes a feeding box and a fluidizing tank arranged below the feeding box. The inner bottom of the feeding box is provided with a vibrating rod. A feeding net is provided on the top of the vibrating rod, and a fluidization device is provided at the junction of the feeding box and the fluidization tank, and the fluidization device includes a discharge pipe. In the present invention, by setting the feeding net, the vibrating rod and the fluidization device, the powder material is unloaded in the form of vibration, and the material is distributed through the fluidization device, and the fluidization wind is passed into the bottom of the fluidization tank, because the fluidization wind passes through the fluidization device At the bottom of the fluidization device, according to the Bernoulli principle of the fluid, the pressure is low at the place where the flow rate is high, and the powder particles falling in the fluidization device are sucked into the fluidization wind, because the fluidization wind is substituted into the powder particles in the form of self-absorption, compared with Since the fluidizing air is directly passed into the powder layer, its resistance is greatly reduced, the requirement for the stability of the fluidizing air is reduced, and the energy consumption required for the same degree of fluidization can also be reduced.
Description
technical field [0001] The invention relates to the technical field of flue gas treatment equipment, in particular to a fluidized tank for a flue gas treatment process. Background technique [0002] There are many kinds of coal-fired flue gas desulfurization technologies, including direct injection of lime / limestone in the furnace and fluidized bed limestone dry flue gas desulfurization, calcium alkali method, amine alkali method, sodium subtraction method, magnesium alkali method and other wet flue gas desulfurization. [0003] The cycle semi-dry method uses the reaction to proceed in the three phases of gas, solid and liquid, and uses the sensible heat of the flue gas to evaporate the water in the absorption liquid, so that the final product is a dry powder. The quicklime is digested with water and then mixed with flue gas for desulfurization. Before the quicklime is digested with water, it is necessary to present the powdered quicklime in a fluid form and then mix it with...
