Abstract

The invention discloses a SCR injection control system for a power generation internal combustion engine based on air inlet flow. According to the system, the air inlet flow of the power generation internal combustion engine can be judged through an air inlet flow meter without re-calibrating the air inlet flow of the power generation internal combustion engine, the working condition of the internal combustion engine is quickly and accurately judged, and the urea water solution injection amount can be adjusted in real time; and NOx in tail gas emission of the internal combustion engine is effectively reduced. According to the SCR injection control system, the product cost is reduced greatly while the judgment of the exhaust flow of the internal combustion engine is achieved, thereby promoting the application of SCR in the power generation industry of the internal combustion engine, and the environment pollution of nitrogen oxide in the exhaust of the power generation internal combustion engine is reduced greatly; and the SCR injection control system is of great significance in guarantee of resident health.

Description

technical field [0001] The invention relates to the technical field of tail gas treatment of power generation internal combustion engines, in particular to an SCR injection control system for power generation internal combustion engines based on intake air flow. Background technique [0002] With the growth of domestic demand for "distributed energy", the domestic gas (methane, coal bed methane, etc.) gradually appearing. According to data, the annual emission of nitrogen oxides from a single 600kW biogas generator can reach 50 tons per year, and its initial emission concentration can reach 8 times the emission standard of "Comprehensive Emission Standards for Air Pollutants GB16297-1996". Nitrogen oxides can lead to asthma and other respiratory diseases, and lead to frequent occurrence of "acid rain". Therefore, the reduction of exhaust pollutants from internal combustion engines for power generation is of great significance to the improvement of residents' health. [000...
