石灰窯爐定期排污的主要任務(wù)是排出沉積在窯爐內(nèi)的水渣，所以定期排污點(diǎn)應(yīng)選在水渣濃度比較大的部位，即窯爐的比較低部位，如下聯(lián)箱或舊式窯爐的泥鼓處。定期排污量的多少主要取決于給水質(zhì)量，一般每隔24h進(jìn)行1次，但如窯爐給水是清潔的凝結(jié)水，補(bǔ)充水用化學(xué)除鹽水或用少量軟化水時(shí)，定期排污的間隔可以很大延長(zhǎng)。定期排污的具體間隔時(shí)間和操作延續(xù)時(shí)間是由化學(xué)車(chē)間根據(jù)爐水的質(zhì)量而定的。自動(dòng)化操控是新技術(shù)石灰窯的重要特色，它的上料，配料、供風(fēng)、供氣、卸灰都是經(jīng)過(guò)電腦自動(dòng)化操控完結(jié)。但也要思考國(guó)情,廠情和價(jià)值本錢(qián),也不是自動(dòng)化程度越高越好.應(yīng)以結(jié)尾作用為準(zhǔn)則.在實(shí)際生產(chǎn)中，石灰在窯爐內(nèi)煅燒并不是理想狀態(tài)下，石灰石表層在810～850℃開(kāi)始分解，而內(nèi)層由于分解表層CaO的氣孔中充滿(mǎn)分解析出的CO2，石灰石內(nèi)層的CO2分壓比窯氣中解溫度也相應(yīng)要高。因此可通過(guò)引風(fēng)機(jī)不斷抽出窯氣，采取負(fù)壓操作，加快CaCO3的分解速度，可縮短石灰石在窯內(nèi)燒成帶的停留時(shí)間。新型環(huán)保石灰窯優(yōu)勢(shì)特點(diǎn)，設(shè)備的特點(diǎn)越多，則它在實(shí)際生產(chǎn)過(guò)程中所發(fā)揮出的優(yōu)勢(shì)也就更多。海南全窯型有效鈣誠(chéng)信合作</p><p
