粗苯在常溫下有較強(qiáng)的揮發(fā)性，因此安全規(guī)范要求在氣溫高于30℃時必須及時開啟噴淋裝置，以降低槽體溫度，防止發(fā)生粗苯蒸汽大量揮發(fā)引起的安全事故及產(chǎn)品損失。該噴淋裝置是架設(shè)在粗苯槽頂?shù)囊蝗Σ紳M小孔的封閉管道，使用中經(jīng)常出現(xiàn)噴淋孔堵塞，需要當(dāng)班操作工每天爬上槽頂進(jìn)行疏通，且苯蒸汽對人體也存在不同程度的傷害。為此，該作業(yè)區(qū)積極查找結(jié)垢堵塞原因，開展小改小革，拆下噴淋管的末端，加裝一個小閥門，改變了管道的封閉性，只要開啟閥門，就能隨時排出雜物，不再堵塞，效果理想。
