A high-efficiency denitrification and dust removal integrated device and its use method

Abstract

The invention discloses an efficient denitration and dust removal integrated device and a use method of the efficient denitration and dust removal integrated device. A denitration and dust removal pipe (12) is arranged in a denitration and dust removal rotating device (1), a partition plate (10) is arranged at one end of the denitration and dust removal rotating device (1), the end part of the denitration and dust removal rotating device (1) is divided by the partition plate (10) into a dust removal zone (7), a denitration zone (8) and a blowing zone (9), one end of the dust removal zone (7) is connected with a draught fan (3), the other end of the dust removal zone (7) is connected with one end of the denitration zone (8) through a flue gas pipe (11), the other end of the denitration zone (8) is connected with a flue gas outlet (4), one end of the blowing zone (9) is connected with a blowing gas inlet (5), and the other end of the blowing zone (9) is connected with a blowing gas outlet (6). According to the efficient denitration and dust removal integrated device and the use method of the efficient denitration and dust removal integrated device, the content of flue gas dust entering a denitration reactor is low, the denitration and the dust removal are conducted in an integrated manner, and the denitration efficiency is high.

Description

technical field [0001] The invention relates to a flue gas purification device, in particular to an integrated device for high-efficiency denitrification and dust removal. The invention also relates to a method for using the high-efficiency denitrification and dust removal integrated device. Background technique [0002] In recent years, with the increase of smog weather in various places and the improvement of people's awareness of environmental protection, the state and local governments have promulgated more stringent environmental protection laws and policies. Industrial furnace flue gas pollutants such as soot and nitrogen oxides are in urgent need of a high-efficiency and energy-saving technology. [0003] At present, flue gas denitrification and dust removal generally adopt separate treatment methods, and SCR reactors are generally used to treat nitrogen oxides in flue gas, while belt dust removal or electric dust removal are generally used for dust removal.

Problems solved by technology

Moreover, at present, most of them are dedusted after denitrification, which leads to the flue gas entering the denitrification reactor containing a large amount of soot, which will affect the activity of the catalyst, thereby affecting the denitrification efficiency.
