一、引言 1982年冬季,由于液化石油气的气质较差,多数用户室内又不采暖,因此残液量比较大,10公斤钢瓶内的残液量常达2～3公斤。公司所属的第一储灌场,冬季日供气量约为8000瓶,而残液倒空能力约为6000瓶/日。而82年以前,由于未能实现瓶瓶倒残,致使残液愈积愈多,不仅增加了换瓶次数,而且影响了钢瓶的周转,导致灌装瓶数和运输量的增加。如能提高倒残速度、增加倒残率,就能在一定程度上减缓上述矛盾,对正压倒残方法的改进,就是为此目的开展工作的。
I. INTRODUCTION In the winter of 1982, due to the poor temperament of LPG, most users did not heat the room, so the amount of residual liquid was relatively large. The amount of residual liquid in a 10 kg cylinder often reached 2 to 3 kg. The company’s first storage and irrigation field has a daily supply of about 8,000 bottles in the winter and a residual liquid emptying capacity of about 6,000 bottles per day. And 82 years ago, due to the failure to achieve the bottle residue, resulting in more and more residual liquid, not only increased the number of bottle changes, but also affected the turnover of the cylinder, resulting in increased the number of bottles and transport volume. If we can improve the speed of culling and increase the rate of culling, we can alleviate the above-mentioned contradiction to a certain extent. The improvement of the method of defusing positive pressure is to work for this purpose.
