Novel SCR (Selective Catalytic Reduction) denitration reactor

Abstract

The invention discloses a novel SCR (Selective Catalytic Reduction) denitration reactor which comprises a reactor body, wherein a plurality layers of pattern plates are arranged in parallel inside the reactor body; a plurality of catalyst cages are uniformly arranged on each layer of the pattern plate; the upper ends of the catalyst cages are arranged on the pattern plates in an upside down manner; the lower ends of the catalyst cages are positioned below the pattern plates; the catalyst cages take the shape of a column; the parts between the inner walls and the outer walls of the catalyst cages are filled with a granular denitration catalyst; the inner walls and the outer walls of the catalyst cages are of steel wire net structures; the bottom ends of the catalyst cages are of airtight plate structures; a manhole gate is arranged on a side wall below each layer of the pattern plate, of the reactor body. The novel SCR denitration reactor is simple and novel in structure, the facility investment is reduced, the problem of reducing operation cost and the like is solved, and the resource utilization rate is increased.

Description

technical field [0001] The invention relates to the field of flue gas purification, in particular to a novel SCR denitrification reactor. Background technique [0002] my country is a big coal-burning country, and a certain amount of dust, SO 2 , nitrogen oxides (NO X ) and harmful metal elements, etc., NO in flue gas X The emission ratio of SO 2 The harm to the environment is more serious, a large amount of nitrogen oxides (NO X ) emissions will cause a series of environmental problems such as acid rain, photochemical smog, ozone layer depletion and greenhouse effect, especially the serious "smog" phenomenon in most parts of the country in recent years, which is rooted in nitrogen oxides (NO X ) emissions to control atmospheric nitrogen oxides (NO X ) emission has aroused global attention, and it is also the focus and difficulty of my country's current atmospheric environment protection. Therefore, NO X processing is particularly important. [0003] Currently on the ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a new type of SCR denitrification reactor, which can change the problems of equipment size, floor area, uniform distribution of flue gas, supporting facilities and other problems in the existing flue gas treatment, so as to reduce equipment investment and reduce operating costs. , improve resource utilization
