Embodiment Construction

[0018] The embodiments of the present invention are described in further detail below: It should be emphasized that the embodiments of the present invention are illustrative rather than limiting, so the present invention is not limited to the embodiments described in the specific implementation methods. Other implementations obtained by those skilled in the art according to the technical solution of the present invention also belong to the protection scope of the present invention.

[0019] A calculation method for evaluation of SCR denitrification catalyst, the method calculates the operating fraction of the denitrification catalyst according to the concentration of nitrogen oxides at the outlet, ammonia escape and denitrification efficiency in the actual operation of the denitrification catalyst, and obtains the actual use of the denitrification catalyst. The method includes the following steps :

[0020] (1) Calculate the SCR denitration catalyst evaluation coefficient n, t...

Abstract

The invention relates to an SCR denitration catalyst assessment calculation method. The method comprises the following steps of (1) calculating an SCR denitration catalyst assessment coefficient n with a formula defined in the specification; and (2) making a continuous curve of change, with time, of the SCR denitration catalyst assessment coefficient n, tracking and analyzing a running condition of a catalyst for a long term according to the change of the curve, and providing data support for SCR denitration catalyst adjustment. According to the method, the calculated catalyst state assessment coefficient n is more accurate and reasonable; actual running conditions of equipment are met; and in actual measurement, implementation can be finished without adding new measurement contents, so that the data support is provided for the SCR denitration catalyst adjustment.

Description

technical field [0001] The invention belongs to the technical field of engineering measurement, in particular to an evaluation calculation method for an SCR denitration catalyst. Background technique [0002] As my country's emphasis on environmental protection and related industries has gradually increased, the identification and testing methods of environmental protection equipment have been greatly improved. Among them, there are corresponding standards and specifications for the detection technology of boiler flue gas desulfurization and denitrification equipment. However, the detection standards at this stage are too simple, and few on-site factors are considered. Among them, there is no specific calculation method for evaluating the catalyst of the selective catalytic reduction reaction (abbreviated as SCR) denitrification device. Contents of the invention [0003] The purpose of the present invention is to propose an evaluation calculation method for an SCR denitra...
