    雙堿法煙氣脫硫原理及工藝流程

    雙堿法煙氣脫硫工藝流程

    Double alkali flue gas desulfurization process flow
    脫硫工藝主要包括5個部分：吸收劑製備與補充；吸收劑漿液噴淋；塔內霧滴與煙氣接觸混合；再生池漿液還原鈉基堿；石膏脫水處理。
    The desulfurization process mainly includes five parts: preparation and supplement of absorbent; Absorbent slurry spray; The droplets in the tower contact and mix with the flue gas; The slurry of regeneration tank reduces sodium base alkali; Gypsum dehydration treatment.
    采用鍛鋼爐的煙氣經換熱降溫到≤200℃，經煙道從塔底進入脫硫塔。在脫硫塔內布置若幹層數十支噴嘴，噴出細微液滴霧化均布於脫硫塔溶積內，煙氣與噴淋脫硫液進行充分汽液混合接觸，使煙氣中SO2和灰塵被脫硫液充分吸收、反應，達到脫塵除SO2的目的。經脫硫洗滌後的淨煙氣經塔頂除霧器脫水，經脫硫塔上部進入煙囪排入大氣。
    The flue gas from the forged steel furnace is cooled to ≤ 200 ℃ by heat exchange and enters the desulfurization tower from the bottom of the tower through the flue. Several layers of ten nozzles are arranged in the desulfurization tower, and the atomization of fine droplets is uniformly distributed in the dissolution of the desulfurization tower. The flue gas is fully mixed with the spray desulfurization liquid, so that SO2 and dust in the flue gas are fully absorbed and reacted by the desulfurization liquid, so as to achieve the purpose of dust removal and SO2 removal. The net flue gas after desulfurization and washing is dehydrated by the tower top demister, and then enters the chimney through the upper part of the desulfurization tower and is discharged into the atmosphere.
    脫硫循環液經塔內氣液接觸除SO2後，經塔底管道流入沉澱池在此將灰塵沉澱下來，清液經上部溢進入反應再生池，在池內與石灰乳液製備槽引來的石灰乳進行再生反應，再生液流入泵前循環槽補入Na2CO3，由泵打入脫硫塔頂脫除SO2循環使用。其中再生產出的CaSO3及煙氣中過剩氧生成的CaSO4於沉澱池中沉澱分離。
    After SO2 is removed by gas-liquid contact in the tower, the desulfurization circulating liquid flows into the sedimentation tank through the pipeline at the bottom of the tower to precipitate the dust here. The clear liquid overflows into the reaction regeneration tank through the upper part, and regenerates with the lime milk introduced from the lime lotion preparation tank in the tank. The regenerated liquid flows into the circulating tank in front of the pump to supplement Na2CO3, and is pumped into the desulfurization tower top to remove SO2 for recycling. CaSO3 produced by regeneration and CaSO4 produced by excess oxygen in flue gas are precipitated and separated in the sedimentation tank.
