在生产氧化沥青的过程中,向釜内沥青原料通入大量空气,发生一系列的化学反应,产生具有窒息性恶臭的气体和部分油气。这种气体混同过剩的空气和水蒸汽,从釜顶排出,严重污染空气,影响人民群众的身体健康。这种尾气经大气冷却,其中携带的沥青、可凝油气及水滴散落在装置内外,直接影响装置卫生。我厂沥青车间广大职工 In the process of producing the oxidized asphalt, a large amount of air is introduced into the raw material of the autoclave, and a series of chemical reactions take place, resulting in gas with asphyxia and some oil and gas. This gas mixed with excess air and water vapor, discharged from the top of the kettle, seriously polluted the air, affecting the health of the people. This exhaust through the air cooling, which carried the asphalt, condensable gas and water droplets scattered inside and outside the device, a direct impact on device hygiene.
