| description | The invention relates to an environment-friendly device for reducing nitrogen oxides in a water-coal-slurry boiler. The device comprises a first shell, a smoke inlet pipeline and a second shell, wherein the smoke inlet pipeline is connected with the interior of the first shell, a heat exchange pipe is fixedly installed in the first shell, and a water inlet and a water outlet are formed in the heatexchange pipe; and the first shell is connected with the interior of the second shell through a first pipeline, the two sides of the inner wall of the second shell are uniformly and fixedly connectedwith a plurality of catalytic plates, and the catalytic plates are provided with a catalyst. Through the cooperation of an impeller and the heat exchange pipe, the device can fully utilize high temperature and flow rate of nitrogen oxide gas for power generation and heat exchange; harmful substances in the nitrogen oxide gas can be effectively reacted and removed through cooperation of the catalytic plates and an alkaline |
