Abstract

The invention relates to a method for ultralow emission of amorphous carbon and organic pollutants in boiler flue gas. A lower combustor, an upper combustor and combustor interlocking control equipment are sequentially arranged on a boiler hearth from bottom to top, adsorbent adding equipment and an adsorbent adding equipment controller are arranged on a boiler outlet flue, a material returning pipeline is arranged at the bottom of trapping and purifying equipment and connected with the lower combustor and the upper combustor, catalytic oxidizing agent adding equipment and a catalytic oxidizing agent adding device controller are arranged on the material returning pipeline, and catalytic oxidizing agent adding and adsorbent adding interlocking control equipment is arranged between the catalytic oxidizing agent adding equipment and the adsorbent adding equipment. The method is high in removal efficiency of amorphous carbon and organic pollutants in the boiler flue gas, low in operation cost, convenient to overhaul, operate and maintain and suitable for purification of amorphous carbon and organic pollutants in the boiler flue gas.

Description

technical field [0001] The invention relates to a method for ultra-low emission of amorphous carbon and organic pollutants in boiler flue gas, in particular to a method comprising a lower burner, an upper burner, burner chain control equipment, a return pipeline, catalytic oxidant adding equipment, catalytic Oxidant adding equipment controller, adsorbent adding equipment, adsorbent adding equipment controller, catalytic oxidant adding and adsorbent adding chain control equipment, and capture and purification equipment are composed of a method for ultra-clean emission of amorphous carbon and organic pollutants in boiler flue gas . Background technique [0002] For oil-fired boilers, gas-fired boilers, and biomass-fired boilers, based on the complexity of fuel properties and the variability of combustion conditions, the combustion products are extremely unstable and diverse in composition, and the composition of the flue gas is difficult to control, and the flue gas is harmles...
