【摘要】：在自主研制的電袋復合除塵器實驗臺上研究了工作電壓、氣流溫度和入口粉塵質(zhì)量濃度對除塵性能的影響,探討了除塵效率和被捕集粉塵粒徑范圍等的變化規(guī)律.結(jié)果表明:工作電壓增大時,總除塵效率提高;氣流溫度超過130℃時,總除塵效率明顯降低;入口粉塵質(zhì)量濃度增大到14.7g/m3以上時,靜電除塵區(qū)除塵效率大幅下降;靜電除塵區(qū)主要除去10μm以上粒徑粉塵,而布袋除塵區(qū)除塵范圍偏向10μm以下的細小顆粒;在實際運行過程中,適當提高工作電壓以及降低煙氣溫度和入口粉塵質(zhì)量濃度,將有助于提高除塵效率和PM2.5的捕集率.
[Abstract]:The effects of working voltage, air flow temperature and inlet dust mass concentration on the dust removal performance were studied on a self-developed electric bag composite precipitator test bench. The variation rules of dust removal efficiency and particle size range of the arrested dust were discussed. The results show that when the working voltage increases, the total dust removal efficiency decreases obviously when the air temperature exceeds 130 鈩，
