液化石油气钢瓶定期检验站,需要用水蒸汽吹扫瓶内的可燃性气体和残留在瓶壁上的石油重组份,以保证检验安全。由于吹扫每只钢瓶用汽量不大,对于每批检验数量不多,不宜使用蒸发量大于实际需要量的工业锅炉,浪费能源,检验成本高。为解决这一难题,我们于1994年10月成功地设计制造了以回收液化石油 Liquefied petroleum gas cylinders at regular inspection stations, the need to use steam to purge the flammable gas bottle and residual oil in the bottle wall heavy components, in order to ensure the safety inspection. Due to the small quantity of gas used for purging each cylinder, for small quantities of each batch of tests, it is not appropriate to use industrial boilers whose evaporation is greater than the actual requirement, thereby wasting energy and testing costs. To solve this problem, we successfully designed and manufactured in October 1994 to recover liquefied petroleum
