1、脱硫效率高。
1. The efficiency of desulphurization is high.
在脱硫塔内,氨水与烟气充分接触,属于气-液反应,瞬时完成,相同反应条件下,是反应速率最快的。
In the desulphurization tower, the ammonia is in full contact with the flue gas, which belongs to the gas-liquid reaction, is completed instantaneously, and the reaction rate is the fastest under the same reaction conditions.
2、同步多功能一体化。具有良好的脱硫和除尘功能,同时NO产生瞬间反应成氮气和水完成脱硝功能。
2. Synchronous multi-function integration. It has good desulfurization and dedusting functions, and NO produces instant reaction of nitrogen and water to complete denitrification.
3、液气比值小。
3. The ratio of liquid and gas is small.
4、系统阻力小。
4. The resistance of the system is small.
由于反应塔属于喷射塔,塔本体阻力比填料塔阻力小,仅为填料塔阻力的1/3。经过阻力计算以及多次实际应用,测试证明塔本体阻力小于1000Pa。
As the reaction tower belongs to the jet tower, the resistance of the tower is less than the resistance of the packed tower, which is only 1/3 of the resistance of the packing tower. Through the calculation of resistance and many practical applications, the test proved that the resistance of the tower is less than 1000Pa.
5、脱硫反应温度区间可变范围大。
5. The temperature range of the desulfurization reaction is variable.
在40℃~180℃反应塔内,脱硫效率依然能够达到95%以上。液体pH值控制在生成(NH4)2SO3范围之内,进而降低了设备的腐蚀(已有反应塔使用10年以上的范例)。循环液的温度越高,硫铵的溶解度越大,运行中一般控制在使循环液接近饱和结晶的浓度以下,使其在塔外结晶,有效避免堵塞现象。
In the reaction tower of 40 to 180, the desulfurization efficiency can still reach more than 95%. The pH value of the liquid is controlled within the range of (NH4) 2SO3, thereby reducing the corrosion of the equipment (an example of the existing reactor used for more than 10 years). The temperature of circulating fluid is higher, the greater the solubility of ammonium sulfate, in the operation of the general control in the circulating liquid concentration close to the saturated crystallization, the crystallization in the tower, effectively avoid clogging.
6、适应烟气量和烟气含硫量的变化。
6, adapt to the change in the amount of flue gas and the sulfur content in the flue gas.
脱硫系统具有较高的可靠性及灵活性,当烟气量发生变化时,控制系统自动及时进行脱硫剂浓度和量调节。当脱硫剂浓度增加时,系统采用独特的结构设计有效防止气体氨的逃逸。进而避免脱硫剂的浪费和可能造成的环境污染问题。
The desulfurization system has high reliability and flexibility. When the amount of flue gas changes, the control system can automatically adjust the concentration and quantity of the desulfurizer in time. When the concentration of the desulfurizer is increased, the system adopts unique structural design to effectively prevent the escape of gas ammonia. To avoid the waste of desulfurizer and the possible environmental pollution problems.
