)發(fā)生爆炸，即粉塵本身具有可燃性，粉塵必須懸浮在空氣中并與空氣混合到爆炸濃度，有足以引起粉塵爆炸的火源。當前兩個(gè)條件出現時(shí)，就會(huì )引起除塵系統發(fā)生爆炸、起火。因為一般除塵器都是吸入空氣后再排出，故除塵系統內氧氣供給充足。據調查，能引起除塵系統起火可能性的主要為靜電火花、自燃發(fā)火、沖擊摩擦和明火。而因靜電引爆粉塵爆炸所占事故比例較大。故在此討論布袋除塵器的靜電問(wèn)題及防爆措施。</p><p><br/></p><p>1.粉塵爆炸機理及特點(diǎn)</p><p><br/></p><p>　　粉塵的爆炸可視為由以下三步發(fā)展形成的：第一步是懸浮的粉塵在熱源作用下迅速地干餾或氣化而產(chǎn)生出可燃氣體；第二步是可燃氣體與空氣混合而燃燒；第三步是粉塵燃燒放出的熱量，以熱傳導和火焰輻射的方式傳給附近懸浮的或被吹揚起來(lái)的粉塵，這些粉塵受熱汽化后使燃燒循環(huán)地進(jìn)行下去。隨著(zhù)每個(gè)循環(huán)的逐次進(jìn)行，其反應速度逐漸加快，通過(guò)劇烈的燃燒，最后形成爆炸。</p><p><br/></p><p>　　這種爆炸反應以及爆炸火焰速度、爆炸波速度、爆炸壓力等將持續加快和升高，并呈跳躍式的發(fā)展。</p><p><br/></p><p>　　可燃粉塵一旦發(fā)生爆炸，會(huì )顯示出如下特點(diǎn)</p><p><br/></p><p>　　1.1發(fā)生頻率高，破壞性強。</p><p><br/></p><p>　　1.2容易產(chǎn)生二次爆炸。</p><p><br/></p><p>　　1.3爆炸產(chǎn)物容易是不完全燃燒產(chǎn)物，與一般氣體的爆炸相比，由于粉塵中可燃物的量相對較多，粉塵爆炸時(shí)燃燒的分解的氣體產(chǎn)物，灰分是來(lái)不及燃燒的。</p><p><br/></p><p>　　1.4爆炸會(huì )產(chǎn)生有毒氣體。一種是一氧化碳；另一種是爆炸物(如塑料)自身分解的毒性氣體。</p><p><br/></p><p>　　2.布袋除塵器中產(chǎn)生靜電問(wèn)題</p><p><br/></p><p>　　2.1除塵設備中的粉塵，通過(guò)管道時(shí)與管壁等相互磨擦和碰撞都會(huì )產(chǎn)生大量靜電。粉塵帶電后通過(guò)除塵器時(shí)附著(zhù)在過(guò)濾器上，由于布袋除塵器采用了間歇式清灰方式，也就導致帶電粉塵的堆積使電場(chǎng)強度逐漸增強。如果附著(zhù)在過(guò)濾器上的粉塵厚度達到某種程度時(shí)，會(huì )使得粉塵表面電場(chǎng)強度達到空氣的介質(zhì)擊穿場(chǎng)強，則在場(chǎng)強最大值區域將出現靜電放電現象，若此時(shí)使得粉塵揚起(如清灰)，且粉塵濃度達到爆炸極限，則很容易引起粉塵爆炸。</p><p><br/></p><p>　　2.2帶有大量靜電的粉塵從過(guò)濾器通過(guò)，進(jìn)入集塵斗后，帶電粉塵越堆積也使得粉堆表面電場(chǎng)強度逐漸增強。如果粉堆表面電場(chǎng)強度達到空氣的介質(zhì)擊穿場(chǎng)強，在場(chǎng)強最大值區域也將出現放電。</p><p></p><p>　　2.3如果過(guò)濾器和集塵斗是絕緣的，或者都是導電性材料制成的，如接地不良，則粉堆表面放電出現之后，放電產(chǎn)生的離子并不能轉移到地面，一種符號的離子被吸向粉堆，另一種符號的離子被排斥，在濾料上或集塵斗上出現很高的表面電荷，此時(shí)很可能引起刷形放電的傳播，如果此時(shí)偶然性出現導體靠近帶電體表面等情況，就能引起大范圍的表面空氣電離，放電能量可達數焦耳。</p><p><br/></p><p>　　此外，如果濾料及集塵斗是導電性材料制成的，但接地不良，則兩者成為帶電孤立導體，導體單次放電能量遠大于絕緣體單次放電能量，因此這時(shí)比兩者都用絕緣材料制成的更危險。</p><p><br/></p><p>2.4如果放置一孤立導體在粉堆表面，導致迅速增大放電能量，若除塵系統入口處未設置金屬分離器，則可能隨粉塵混入粉堆中鐵制品等金屬，此時(shí)有可能出現放電現象。</p>
