Description
Technical field
The utility model relates to power generation by waste combustion fields, and specifically, the utility model relates to a kind of for macromolecule denitration
Feeding device.
Background technique
With the continuous development of China's economy the continuous quickening of urbanization process and process of industrialization, environmental pollution is increasingly
Seriously, country is also higher and higher to the attention degree of environmental protection.Power generation by waste combustion factory can generate a large amount of nitrogen oxidation during the burning process
Object NOx is closed, flue gas, which is directly discharged into atmosphere, will cause serious environmental pollution, and denitration technology is that power plant construction runs general ring
Technological means is protected, excessive NOx in flue gas can be effectively removed.Domestic denitration technology general at present has SCR, and (selective catalysis is also
Former method), SNCR (selective non-catalytic reduction method), wherein SNCR simple process, denitration efficiency is lower, is not able to satisfy increasingly strict
Environmental requirement, SCR denitration efficiency is higher, but its complex process, especially low-temperature SCR catalyst are expensive, and service life is short,
