Abstract

The invention discloses a filtering dust removing denitration integrated device comprising a dust removing denitration tower, wherein the dust removing denitration tower is provided with a backflushing section, a denitration section, a dust removing section and an ash collecting section from top to bottom in turn; wherein a mounting plate is arranged between the dust removing section and the denitration section, the mounting plate is provided with a plurality of dust removing pipes, and a dust inlet is arranged at the lower end of the dust removing section; the dust removing pipe comprises a head, a neck and a body, wherein the neck has a circle of neck groove recessed toward the top of the dust removing denitration tower, so that a circle of head flange protruding toward the bottom of thedust removing denitration tower is formed on the head connected to the neck, a circle of mounting flange connected with the neck groove in an embedded manner and a mounting groove for containing thehead flange are correspondingly arranged on the mounting plate, and by use of the filtering dust removing denitration integrated device, e dust removing and wet denitration are performed, the airspeedof flue gas and other reaction gases are controlled during the treatment process, a large amount of flue gas can be efficiently processed, and the dust removing and denitration efficiency of the fluegas can be improved.

Description

Technical field [0001] The invention relates to waste gas treatment, in particular to an integrated device for filtering, dust removal and denitration, and also to an integrated process for filtering, dust removal and denitration. Background technique [0002] Nitrogen oxide (NOx) is one of the main pollutants in the atmosphere, and it is also the focus and difficulty of air pollution control and environmental protection. my country's coal-based energy structure will not change significantly in the next few decades. The combustion of coal is likely to cause serious air pollution, especially the NOx in coal-fired flue gas, which is extremely harmful to human health and the environment. In the near future, environmental issues will become an important factor restricting economic development. Protecting and improving the environment is a necessary condition to ensure the sustainable development of my country's economy. In addition, the temperature of the glass furnace is high, the ...
