Abstract

The invention relates to a desulfuration dust collection process which comprises the following steps: pretreating a flue gas, introducing into a dry electric dust collector for dust collection, introducing the flue gas after primary dust collection into a wet desulfuration tower for desulfuration and dust collection, and introducing the flue gas after dust collection and desulfuration into a wet dust collection device for further dust collection, wherein at least two electric fields are arranged in the dry electric dust collector; at least one electric field is provided with a high-frequency power supply; at least one electric field is provided with a pulse power supply. By adopting the process, good dust collection and desulfuration effects can be achieved, the filtration efficiency is not less than 99.95%, and the outlet emission is less than or equal to 30 mg / Nm<3>.

Description

technical field [0001] The invention relates to the field of gas pollutant treatment, in particular to sulfur and dust removal treatment of flue gas. Background technique [0002] Environmental protection is the basic state policy of our country. The state attaches great importance to environmental protection, taking it as an important means of transforming the mode of economic development, as a fundamental measure to promote the construction of ecological civilization, and taking the significant reduction of the total discharge of major pollutants as a binding indicator for economic and social development. . At present, the overall deterioration of my country's environmental conditions has not been fundamentally curbed, environmental contradictions are prominent, and the pressure continues to increase. Environmental problems have become one of the important factors threatening human health, public safety and social stability. As a large coal consumer, thermal power plant...
