均流板

对加均流板的SDA逆向喷射，与无喷射气相场相比，由于初始浆滴速度与气相间的速度差较大，浆滴对塔内烟气流场有明显扰动作用。

Versus increasing flow equalization board in SDA under reverse injection comparied of the gas phase filed without injection . Since the initial speed difference is great between slurry and gas , the slurry play a obviously disturbed effect for flue gas flow on the tower .

结果表明：对于不同的过滤器模型，均流板的设计应有不同的方式，不能单独依照经验。

The results show that : to different filter model , we should design different flow rectifier rather than only according to empirical .

当浆液喷射压力过大时，浆液冲到均流板上部；过小时喷射的射程不够充分，与烟气接触的时间短，这些都会影响脱硫效率。

When too much injection pressure , the slurry will into the equalization board are the Department of the hour jet has a range insufficient , and the contact time is short , these will affect the desulfurization efficiency .

防磨改造的主要措施是在尾部烟道处安装均流孔板，以降低局部烟气流速，控制飞灰均匀分布，达到锅炉受热面防磨的效果。

In the anti-attrition transformation of the boiler low-temperature heating surface , uniform flow orifice was mounted on the rear flue to reduce local flue gas velocity and control the even distribution of fly ash .
