圖2.97 可燃氣(qi)體排(pai)氣(qi)筒或放空(kong)管(guan)高度(du)示意(yi)圖注：陰影部分(fen)為平臺(tai)或建筑物的設置范圍(wei)

 對有毒、可燃(ran)介質應(ying)按項目(mu)規定(ding)(ding)引至指(zhi)定(ding)(ding)的收集(ji)系(xi)(xi)統(tong)(tong)、火炬系(xi)(xi)統(tong)(tong)或放(fang)空場所。當幾根支管(guan)合并成一(yi)根集(ji)合管(guan)向總管(guan)排放(fang)時，集(ji)合管(guan)的截(jie)面(mian)積應(ying)不小于(yu)(yu)幾根支管(guan)截(jie)面(mian)積之和。排放(fang)閥(fa)出口(kou)管(guan)道不得小于(yu)(yu)閥(fa)門出口(kou)的直徑，并由工藝系(xi)(xi)統(tong)(tong)專業根據實際配管(guan)核算放(fang)空、放(fang)凈的壓(ya)力降，使之適應(ying)泄放(fang)系(xi)(xi)統(tong)(tong)的要(yao)求。
