The invention discloses a denitration device for a power plant, which comprises a urea storage tank, a double-fluid injection device, a mixing pipeline and a catalytic reactor. The dual-fluid injection device is provided with a urea liquid inlet and a compressed air inlet. The urea liquid inlet is connected to the urea storage tank through the first delivery pipe. The first delivery pipe is provided with a peristaltic pump. The compressed air inlet is connected to a compressed air source. The mixing pipe is provided with a high-temperature flue gas inlet connected to the smoke exhaust pipe of the power plant, a reducing agent inlet connected to the injection outlet of the dual-fluid injection device, and a mixed fluid outlet connected to the catalytic reactor; it also includes a control system, smoke exhaust The pipeline is equipped with a temperature sensor, a flow sensor and a NOx concentration detector near the high-temperature flue gas inlet, and the control system is connected and communicated with the temperature sensor, flow sensor, NOx concentration detector and peristaltic pump respectively. The invention has simple structure and high denitrification efficiency.
Description
technical field [0001] The invention relates to the technical field of power plant denitrification, in particular to a power plant denitrification device. Background technique [0002] The high-temperature flue gas discharged from power plants contains a large amount of nitrogen oxides, and the discharge of this part of nitrogen oxides has brought serious harm to the natural environment and human life. For example, nitrogen oxides can nitrify human hemoglobin and cause respiratory inflammation. Nitrogen oxides are one of the main causes of acid rain and acid fog. Nitrogen oxides also participate in the destruction of the ozone layer. Therefore, nitrogen oxides have become a major public hazard today. In order to control and reduce their impact on the atmospheric environment Both the national and local environmental protection departments have clear and mandatory emission standards for the emission of nitrogen oxides in industrial production waste gas. At present, many kind...
