The characteristics of SNDR
desulfurization and denitrification
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.
