1、建筑环境与设备工程专业毕业实习报告一、实习目的:建筑环境与设备工程专业燃气工程生产实习,是重要的实践教学环节,通过生产实习可以使学生对燃气专业从事的领域和业务,以及燃气工程情况建立一定的感性认识,使同学们明确自己的专业范围,了解专业一些简单的设计、施工、维护管理、调试等方面的知识。为以后的就业打下必要的理论和实践基础。二、实习内容:1、对LPG的认识实习液化石油气(LiquefiedPetroleumGas,简称LPG)经常容易与LNG混淆,其实它们有明显区别。LPG的主要组分是丙烷(超过95%),还有少量的丁烷。LPG
2、在适当的压力下以液态储存在储罐容器中,常被用作炊事燃料。在国外,LPG被用作轻型车辆燃料已有许多年。LPG气化站的作用式将站区内储存的液态LPG通过气化、调压等工艺过程形成气态LPG输送到城市管网中,其主要核心工艺设备之一就是LPG气化器,液态LPG的气化器中吸收热量变成气态LPG。LPG气化器类型主要有热水循环式气化器、电热式气化器、空温式气化器等。1.1、各类气化器运行原理:air,keephouseairfresh,cooling,moisture,reducethebodytemperatureofthechic
