电除尘器高压脉冲供电收尘技术研究

Removing Dust Technique Study on High Pressure Impulse Electro Precipitator

介绍了脉冲供电研究概况 ,脉冲供电原理及收尘试验等 ,这种脉冲供电是在低压端产生脉冲 ,升压整流后形成脉冲供电 ,脉冲幅值是基础直流的 1～ 4倍 ,且可调。它具有构思独特、造价低 ,简单实用等特点。实验结果表明 ,在基本上保持同工况条件下 ,脉冲供电比直流供电降低出口烟气含尘浓度 3 0 .5 %～ 74.4%。

The research situation on impulse power supply,the principle of power supply,and the removing dust experiments are introduced.It produced impulse at the low pressure,and formed impulse power supply through boost commutation.The impulse range is 4 times of the base direct current value and can adjusted.The technique has the characteristic of design particularly,low cost,simpleness and practicality.The experiment indicate:In the same circumstance,the smoking density in the impulse more reduced 30.5～74.4 percent than the direct current.
