Abstract

The present invention discloses a flue gas treatment system for ceramic production. The flue gas treatment system comprises a boiler, a denitration system, a desulfurization system, a heat exchanger,a chimney and a gas source; the boiler, desulfurization system, and chimney are sequentially connected by pipelines; flue gas is desulfurized by the desulfurization system and denitrated by the denitration system; denitration spray heads spray a reducing agent prepared in a reducing agent preparation module into the boiler to remove nitrogen oxides in the flue gas generated by the boiler; the heatexchanger is arranged in a flue inlet heat exchange section and a flue outlet heat exchange section; heat of raw flue gas not subjected to desulfurization by a desulfurization tower is transferred tonet flue gas subjected to the desulfurization by the desulfurization tower via the heat exchanger; liquid water carried by the net flue gas is converted into gaseous water, thereby achieving an effect of eliminating white smoke. The flue gas treatment system organically combines the three purification devices for the denitrification, desulfurization and white smoke elimination together, is simplein structure, low in operation cost and good in desulfurization and denitration effects, and reduces environmental impacts in the ceramic production.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a flue gas treatment system for ceramic production. Background technique [0002] In the production of ceramics, a large amount of industrial waste gas will be generated. These waste gases include sulfur, nitrogen and other pollutants. Therefore, these industrial waste gases need to be treated. In addition, due to the low temperature and high humidity of the flue gas, the flue gas discharged from the chimney Mixing with cold air will cause the water vapor in the flue gas to condense to form white smoke, which will affect the appearance of the environment. [0003] In the power industry, the selective non-catalytic reduction denitrification system is generally used to denitrify the flue gas. Due to the difference in the concentration and content of nitrogen oxides produced in the ceramic manufacturing industry, the concentration of nitrogen oxides produced in the ...
