A system for cement SCR denitration and tail gas treatment, comprising an intake flue, a high-temperature electrostatic precipitator, an outlet flue and a denitration reactor, characterized in that the intake flue is connected to the top inlet of the high-temperature electrostatic precipitator, The bottom of the high-temperature dust collector is provided with a plurality of dust collector hoppers, and the side of the high-temperature dust collector is provided with an air outlet, and the air outlet is connected to the denitration reactor through the outlet flue, and the denitration reactor includes a multi-layer catalyst Ceramic material, multiple soot blowers, heat exchangers, compressed air delivery pipes, the soot blowers include rake soot blowers and sonic soot blowers, which are respectively arranged in The upper and both sides of the catalyst ceramic material improve the denitrification efficiency, reduce the consumption of ammonia water, and reduce the escape of ammonia; optimize the process, save the evaporation process of ammonia water, reduce costs and operating costs, and use a spiral scrubber to desulfurize the exhaust gas, which improves the sulfuration in the exhaust gas. the absorption rate of the substance. |
