Abstract

The invention discloses an industrial lime desulfurization technical process and a device thereof, and relates to the field of lime desulfurization. Aiming at problems that the existing industrial lime desulfurization efficiency is low and labor consumption is high, a technical scheme is provided, wherein the device includes an absorption column, a circulating pump circulating pool, a filter press, a lime bin and a lime pool, the absorption column is mounted at the top end of the circulating pool, three circulating pumps with the same structure are mounted around the absorption column, water inlets of the circulating pumps are connected with the circulating pool, water outlets of the circulating pumps are connected with the absorption column, and one side of the circulating pool is connected with the filter press. According to the invention, flue gas particles generated by desulfurized water can be solved, the problem of water quality of desulfurized water can be solved, the phenomenonof discharge of desulfurized water is solved, the desulfurized water can be recycled for a long time, resources are saved, the problems of scaling and blockage of a desulfurization pipeline and a spray head are effectively controlled, the desulfurization efficiency is improved, the manual operation time is reduced, and the process and the device are suitable for popularization.

Description

technical field [0001] The invention relates to the field of lime desulfurization, in particular to an industrial lime desulfurization process flow and a device thereof. Background technique [0002] The principle of quicklime desulfurization is actually a process of neutralization reaction. The sulfur dioxide generated by sulfur combustion is absorbed by the reaction of quicklime and SO2 (CaO+SO2=CaSO3), so that the reaction is converted into a stable desulfurization by-product, so as to achieve the purpose of desulfurization. Sulfur dioxide is an acidic valence, and quicklime is a strong alkaline medium. Using its acid-base neutralization and redox principles, the kinetic energy provided by the circulation pump and the booster fan is used to carry out reverse contact of the gas-liquid two-phase in the absorption tower. The reaction produces CO2 and hydrous calcium sulfate. That is to say, the quicklime is sent to the feeding platform, and is fed into the silo from the fee...
