【摘要】：采用搭建的350 m~3/h燃煤熱態(tài)實(shí)驗(yàn)平臺(tái),測(cè)量電除塵出口不同粒徑細(xì)顆物脫除效率,考察噴霧降溫對(duì)電除塵放電特性、煙氣酸露點(diǎn)、粉塵比電阻及除塵效率的影響.結(jié)果表明:當(dāng)煙氣溫度由130℃降低到90℃,相對(duì)濕度由6%提高到12%時(shí),電除塵擊穿電壓升高,粉塵比電阻降低;同時(shí)煙氣酸露點(diǎn)溫度隨著相對(duì)濕度增加而提高;電除塵質(zhì)量脫除效率變化不明顯,但在0.1~1.0μm區(qū)間的顆粒數(shù)量脫除效率可提高10%;根據(jù)低低溫電除塵運(yùn)行經(jīng)驗(yàn)可知,噴水降溫到煙氣酸露點(diǎn)以下,合理控制煙氣灰硫比可避免產(chǎn)生煙道腐蝕.
[Abstract]:The removal efficiency of fine particles with different particle sizes at the outlet of electrostatic precipitator was measured using a 350mm3 / h coal-fired thermal experimental platform. The effects of spray cooling on discharge characteristics, acid dew point of flue gas, specific resistance of dust and efficiency of dust removal were investigated. The results show that when the flue gas temperature decreases from 130 鈩，
