Abstract

The invention relates to an efficient integrated desulfurization and denitrification device for coal-fired boiler fuel gas and an implementation method of the device. The efficient integrated desulfurization and denitrification device for the coal-fired boiler fuel gas comprises a desulfurization and denitrification agent conveying module, a desulfurization and denitrification agent metering and spraying module and a circulating spraying system, wherein the desulfurization and denitrification agent conveying module is connected with the desulfurization and denitrification agent metering and spraying module, and the desulfurization and denitrification agent metering and spraying module is connected with the circulating spraying system. The device and the method provided by the invention have the advantages that defects of the conventional desulfurization and denitrification process and equipment such as large investments, complicated operation procedures, a high failure rate and the like are overcome, strength and acid and alkali resistance are guaranteed, the contact between fuel gas and circulating slurry is enlarged, and the desulfurization and denitrification efficiency is improved.

Description

technical field [0001] The invention relates to a desulfurization and denitrification device, in particular to an integrated device for high-efficiency desulfurization and denitrification of flue gas of a small coal-fired boiler and a realization method thereof, belonging to the technical field of environmental protection mechanical equipment. Background technique [0002] Although the use of coal-fired boilers has made great contributions to my country's economic development, the emission of flue gas and exhaust gas also causes huge pollution to my country's air environment. SO2 and NOX pollution has surpassed smoke pollution and become the largest pollutant in the atmospheric environment. [0003] Desulfurization in the prior art mainly includes wet desulfurization, semi-dry desulfurization, dry desulfurization, etc. The wet desulfurization mainly includes desulfurization processes such as limestone-gypsum method, magnesia method, ammonia method, alkali method, etc. Current...
