▎ 摘　　要

NOVELTY - The method involves passing magnetic induction line of a rotating magnetic pole through an adsorption chamber. A flue gas guide structure (4) guides the flue gas to form turbulent flow in a cavity (1). The flue gas enters the denitration device after being adsorbed by the adsorption chamber after forming the turbulent flow. The adsorption chamber is provided with multiple interlayer (1). The interlayer is provided with multiple compartments. The compartment is provided with an adsorption ball (6). The adsorption ball rolls in the compartment. The surface of the adsorption sphere is provided with a modified graphene oxide layer, and modified oxide graphene is loaded with magnetic iron oxide. The rotating magnetic pole controls the rolling of the adsorption ball to improve the adsorption efficiency. The selective catalytic reduction (SCR) system is provided with a transverse plate type catalyst (2). The surface of the transverse plate type catalyst is provided with a hole. USE - Processing method of waste incineration flue gas. ADVANTAGE - The method enables pre-treating the flue gas before the SCR denitration, thus reducing the content of arsenic-containing compound and calcium oxide in the gas, reducing the influence of arsenic compound in the gaseous gas to the catalyst in the system, and improving the efficiency of the system. The method allows controlling the rolling of the adsorption ball by rotating the magnetic pole, thus improving the adsorbent efficiency. The catalyst is provided with a trumpet-shaped hole, so that the surface area of the catalyst is improved, and the catalyst reaction utilization rate is improved. The air flow speed in the hole between the two sides of the loudspeaker is accelerated, thus accelerating the airflow to avoid the accumulation of the adhesive, and forming negative pressure in the small aperture of the periphery of the hole. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a denitration pre-processing device. 1Cavity 2Transverse plate catalyst 3Spray gun 4Flue gas guide structure 5Interlayer 6Adsorption ball
