Abstract

The invention relates to an efficiency calculation method for a novel SCR (Selective Catalytic Reduction) denitration device. The efficiency calculation method comprises the following steps: (1) selecting and sampling a sampling measuring point in the manner as specified in GB / T16157-1996 Method for Determining Particulate Matters in Stationary Pollution Source Exhaust Gas and Sampling Gaseous Pollutants 4.2; and (2) performing sampling measurement for flue gas flow speed, oxygen concentration and nitric oxide concentration at each sampling point at the inlet and outlet of the SCR denitration device, adding the flue gas flow speed and calculating nitric oxide concentration and efficiency in the flue gas. According to the efficiency calculation method, the flue gas flow speed is added as the factor participating into the calculation in a detection process, the calculated nitric oxide concentration is more accurate and scientific, and the calculated denitration efficiency more conforms to the practical operation condition of the equipment.

Description

technical field [0001] The invention belongs to the technical field of engineering measurement, in particular to a method for calculating the efficiency of a novel SCR denitrification device. 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 desulfurization and denitrification equipment for boiler flue gas. However, the detection standards at the present stage are too simple. In order to facilitate on-site detection and calculation, fewer on-site factors are considered. Among them, the detection method of the selective catalytic reduction reaction (SCR) denitrification device has a simple calculation method and few other factors considered. Only the nitrogen oxide content and oxygen content in th...
