某冷冻厂氨油分离器出口管道爆炸辽宁某冷冻厂在机房中新装4台 LN—150冷凝器。在对冷凝器和高压排气管道进行空气试压前,曾列油分离器等日设备及管路进行了抽真空操作,认为已经“无氨”后,开始空气试压检漏。本来有一根不通过旧系统的专用管路用于试压,但因管径较小升压缓慢未采用。而直接通过油分离器、旧菅路向冷凝器试压。经过半天的连续运 A refrigeration plant ammonia oil separator outlet pipe explosion Liaoning refrigeration plant in the engine room to install 4 LN-150 condenser. In the condenser and high-pressure exhaust pipe before the air pressure test, was oil separator and other daily equipment and piping were vacuum operation, that has been “no ammonia”, began air pressure test leak. Originally, there was a special pipeline that did not pass through the old system for pressure test but was not adopted due to the slow increase of diameter. Directly through the oil separator, the old Sugang Road to the condenser pressure test. After half a day of continuous transport
