style="font-family:宋體">安裝粉塵檢測儀是否能有效防護粉塵爆炸，首先了解下為什么會發(fā)生粉塵爆炸。粉塵爆炸原理很簡單，和氣體爆炸原理差不多，但是畢竟一個是氣</span>-<span style="font-family:宋體">固混合爆炸，一個是純氣體爆炸，所以性質(zhì)上肯定有不同。</span></span></p><p><span style=";font-family:Calibri;font-size:14px"><span style="font-family:宋體">粉塵爆炸的威力有時候要比氣體爆炸威力大好多，道理也很簡單，比如煤粉遇到氧氣，產(chǎn)生化學(xué)反應(yīng)，產(chǎn)生二氧化碳，憑借高中化學(xué)知識也可以推出，這個過程會釋放大量氣體和熱量。從固體到氣體的這個過程，體積的膨脹往往要比從氣體到氣體的膨脹要大的多，所以威力一般都要比氣體爆炸強。</span></span></p><p><span style=";font-family:Calibri;font-size:14px"><span style="font-family:宋體">一般容易引起爆炸主要有</span>3<span style="font-family:宋體">個方面的原因。</span></span></p><p><span style=";font-family:Calibri;font-size:14px">　　1<span style="font-family:宋體">、靜電，尤其是一些粉塵在管道中運輸?shù)臅r候，與管道的摩擦也會產(chǎn)生靜電，甚至?xí)a(chǎn)生火花。</span></span></p><p><span style=";font-family:Calibri;font-size:14px">　　2<span style="font-family:宋體">、人為原因，比如在粉塵場所吸煙、粉塵場所不按照規(guī)定放置防爆燈、對粉塵監(jiān)控不到位使其達到了爆炸范圍、或者沒有按照規(guī)定安裝除塵裝置等。</span></span></p><p><span style=";font-family:Calibri;font-size:14px">　　3<span style="font-family:宋體">、泄壓。一旦出現(xiàn)粉塵爆炸，如果人暴露在粉塵中，這個一定會產(chǎn)生傷亡，措施只能是及時送醫(yī)院搶救。但是如果是運輸粉塵的管道出現(xiàn)爆炸，那為了避免連鎖反應(yīng)，可以在管道有關(guān)部位設(shè)置泄壓口。一旦出現(xiàn)爆炸，通過泄壓口，釋放能量減少損失。</span></span></p><p><span style=";font-family:Calibri;font-size:14px"><span style="font-family:宋體">其實在安裝完粉塵檢測儀之后它就會有一個報警裝置，只要粉塵的濃度超過警戒值就會發(fā)出警報，我們能做的就是進行人員的疏散和通風(fēng)。</span></span></p><p><br/></p> </div> <div id="ltrj1tr"
