Abstract

An economical catalyst component for desulfurization and destocking belongs to the field of environmental protection equipment. It is characterized in that it includes a porous base material, a denitrification catalyst liquid material and a desulfurization spray system; wherein the porous base material and the denitration catalyst liquid material account for 90% and 10% respectively, and the denitration catalyst liquid material is infiltrated on the surface of the porous base material. The invention can simultaneously purify sulfur-based and nitro-based pollutants in flue gas, and protect and purify the atmospheric environment.

Description

technical field [0001] The invention belongs to the field of environmental protection equipment for filtering chemical pollutant tail gas, and in particular relates to an SCR denitration catalyst assembly for simultaneous sulfur removal. Background technique [0002] The emission of major air pollutants in my country is huge. In 2010, the total emissions of sulfur dioxide and nitrogen oxides were 22.678 million tons and 22.736 million tons respectively, ranking first in the world. The emission of smoke and dust was 14.461 million tons, both far exceeding the environmental carrying capacity. . The key areas account for 14% of the country's land area, concentrate nearly 48% of the country's population, generate 71% of the total economic output, consume 52% of coal, and emit 48% of sulfur dioxide, 51% of nitrogen oxides, 42% of % of soot and about 50% of volatile organic compounds, the emission intensity of pollutants per unit area is 2.9 to .6 times the national average level,...
