Abstract

The invention discloses a flue gas dehumidification process. The flue gas dehumidification process comprises the following steps of S1, primary dust and mist removal, wherein flue gas to be dehumidified after spray desulfurization is firstly dedusted by a multi-cyclone dedusting and demisting device; S2, cooling is performed to separate out saturated water, wherein after primary dedusting and demisting, the flue gas is cooled by a flue gas cooling and dehumidifying device, and the saturated water is separated out from the cooled flue gas; S3, secondary dust and mist removal, wherein the cooledflue gas is subjected to secondary dust and mist removal through multi-cyclone; and S4, the flue gas is reheated for flue gas electric dedusting. The process has the characteristic of no leakage; a cooling side and a heating side are completely separated; cooling of raw flue gas, cooling and dehumidification of wet flue gas and re-heating of the wet flue gas by the whole system are all subsystems; no flue gas and fly ash are leaked among the subsystems; the removal efficiency of SO2 and fly ash is not influenced in the process; and the design of the process can well adapt to various flue gasconditions, and has good economical efficiency and reliability.

Description

technical field [0001] The invention belongs to the technical field of flue gas treatment, in particular to a flue gas dehumidification process. Background technique [0002] Smoke is a mixture of gas and smoke and is the main cause of air pollution in residential areas. The composition of the flue gas is very complex. The gas includes water vapor, SO2, N2, O2, CO, CO2, hydrocarbons, and nitrogen oxides. The smoke includes fuel ash, coal particles, oil droplets, and high-temperature cracking products. Therefore, the pollution of flue gas to the environment is the compound pollution of various poisons. The harmfulness of smoke to the human body is related to the size of the particles. The most harmful to the human body is the floating dust with a diameter of less than 10 microns, especially the most harmful dust of 1-2.5 microns; [0003] For urban heating enterprises, reducing white smoke emissions is a phenomenon-based indicator of whether environmental protection can mee...
