          【脱硫脱硝】

           

              SNDR氨法脱销脱硝的亮点

              1、脱硫脱硝共用一台冷却塔;

              2、防止氨、气溶胶、亚微米粉粒子的潜流;

              3、适应烟气量和烟气含硫量的转变;

              4、适应烟气中粉尘含量的转变;

              5、不需要催化装置,入股、运作费用低;

              6、系统阻力低,设施占地面积小。

              SNDR脱硫脱硝的特色

             (1)脱硫效率高。
              在脱硫塔内,氨水与烟气充分接触,属于气-液反应,时而成功,相同反应条件下,是影响速率最快的。
             (2)同步多功能一体化。具有优秀的脱硫和除尘功能,同时NO产生瞬间反应成氮气和江完成脱硝功能。
             (3)液气比值小。
             (4)系统阻力小
              鉴于反应塔属于喷射塔,塔本体阻力比填料塔阻力小,仅为建材塔阻力的1/3。途经阻力计算以及多次具体利用,面试证明塔本体阻力小于1000Pa。
             (5)脱硫反应温度区间可变范围大
              在40℃~180℃钟塔内,脱硫效率依然能够达到95%上述。液体pH值控制在变化(NH4)2SO3规模之内,进而降低了设备的腐蚀(已有反应塔使用10年以上的老规矩)。循环液的温度越高,硫铵的力度越大,运作中常见控制在使循环液接近饱和结晶的浓度以下,使她在塔外结晶,使得避免堵塞现象。
             (6)适应烟气量和烟气含硫量的转变
              脱硫系统具有较高的可靠性及灵活性,顶烟气量发生变化时,控制系统自动及时进行脱硫剂浓度和量调节。顶脱硫剂浓度增加时,系统采取独特之组织设计有效防止气体氨的潜流。进而避免脱硫剂的浪费和可能性造成的环境污染问题。
             (7)适应烟气中粉尘含量的转变
              系统具有高效除尘功能,烟气中粉尘在脱硫塔内得到实惠捕集,同时,系统中设置了固液分离装置,使得贯彻粉尘的托收再采取,也避免了系统内粉尘杂质沉淀和堵塞。
             
             
                                 
           
           
                               Desulfurization and  denitration
                    SNDR ammonia denitration advantages out of stock
             one ,  desulfurization denitration share a reaction tower ;
             two, to prevent the escape of ammonia, aerosol, submicron particles Rice noodles;
            three, to adapt to the change of flue gas and flue gas sulfur;
            four, to adapt to the change of dust content in flue gas;
            five, do not need the catalytic device, investment, low running cost;
            six, the system of low resistance, small footprint devices.
              The characteristics of SNDR  desulfurization and denitrification
             ( one)  high desulfurization efficiency .
               In the desulfurization tower, full contact ammonia water and flue gas, belonging to the gas - liquidreaction, instantaneous, the same reaction conditions, the reaction rate is the fastest.
             (two) the synchronous multi functional integration. Has good desulfurization and dust removal function, and NO generates instant response to nitrogen and water complete denitrificationfunction.
            (three) the liquid to gas ratio is small.
            (four) small system resistance
            Because the reaction tower belongs to spray tower, tower body resistance than the packed towerresistance is small, only packed tower resistance in 1/3. After the calculation of resistance and several practical applications, tests prove that the tower body resistance of less than 1000Pa.
            (five) the desulfurization reaction temperature interval variable range
             At 40 to 180 DEG C reaction tower, the desulfurization efficiency can achieve above 95%. Liquid pHvalue control in the generation of (NH4) 2SO3 range, and reduce the corrosion of the equipment(existing reaction tower more than 10 years of use case). The circulating liquid temperature is higher, the greater the solubility of ammonium sulfate, in the operation of the general control in thecirculating fluid saturated concentration below close to crystallization, the crystallization in the tower effectively avoid clogging.
            (six) to adapt to the change of flue gas and flue gas sulfur
            The desulfurization system has high reliability and flexibility, when the flue gas volume changes, the automatic control system for timely desulfurization agent concentration and the amount ofadjustment. When increasing the desulfurization agent concentration, the system adopts the unique structure design effectively prevent the escape of gas ammonia. In order to avoid the problem of environmental pollution of the waste desulfurizer and possible.
            (seven) to adapt to the change of dust content in flue gas
           The system has the function of efficient dust, dust in the smoke in the desulfurizing tower effectivelytrap, at the same time, the system set up the solid-liquid separation device, the effective realization of the dust recycling, but also to avoid the dust precipitation of impurities and blockage in the system.
