Abstract

The invention relates to an SNCR (selective non-catalytic reduction) and ozone flue gas denitrification device. The device comprises a boiler (1), wherein an air preheater (2) and a boiler economizer (4) are arranged in the boiler (1), the air preheater (2) is arranged above the boiler economizer (4), a spray gun area (3) is arranged between the air preheater (2) and the boiler economizer (4), an atomization area of the spray gun area (3) is an SNCR reaction area, an air outlet of the air preheater (2) is connected with a flue gas delivery pipeline (7), the other end of the flue gas delivery pipeline (7) is connected with an inlet end I of a mixer (5), an inlet end II of the mixer (5) is connected with an ozone generator (6) of an ozone delivery pipeline (8), and an outlet end of the mixer (5) is connected with a reacted gas delivery pipeline (9). The device is high in denitrification efficiency and low in investment cost, requires less equipment and has the advantages that the investment is saved and site limitation is avoided, and the project cost and the running cost are reduced.

Description

[technical field] [0001] The invention relates to the technical field of nitrogen oxide treatment, in particular to an SNCR+ozone flue gas denitrification device. [Background technique] [0002] At present, SCR technology or SNCR technology is commonly used in flue gas denitrification. Although it plays an active role in reducing nitrogen oxides and improving the environment, according to the current use, some new problems have emerged, such as, High operating cost and corrosion, complex control system, high site requirements, and more steel structures. Therefore, it will be of great significance to provide a flue gas denitrification device that can reduce engineering cost and operating cost, and has high denitrification efficiency, less equipment required, and less investment cost. [Content of the invention] [0003] The object of the present invention is to solve the above-mentioned deficiencies and provide a kind of SNCR+ozone flue gas denitrification device, which not...
