移动式气化装置的开发及应用的讨论

1、 /移动式气化装置的开发及应用的讨论1问题的提出Of the 1佛山市燃气总公司自1992年底成立以来，致力于发展佛山市区的管道供气业务，现已建成总气化能力为11吨小时的三座小区气化站并实行联网供气，铺设埋地管网180多公里，现有管道气居民用户4万多户，管道气工商业用户200多户。近两年来，随着工商业用户的不断增加，特别是一些陶瓷企业、制罐企业的生产不可间断性对作为供气企业的燃气总公司提出了更高的标准和要求确保连续稳定的供气;但现实的情况是由于新旧管网的驳接、原有管网设施的维护、管网紧急事故的处理等多方面的客观原因，必须对已通气的部分管网实施停气

2、，这就必然会严重影响工商业用户的生产。为了解决这一矛盾，必须寻找一种可移动的气源来对工商业用户或成片小区在特殊情况下实施临时供气，也即开发一种移动式的气化装置。Gas corporation since its inception at the end of 1992, foshan city, foshan city, committed to the development of the pipeline gas supply business, has established the total gasification capacity of 11 tons/hour of three

3、 plot gasification and gas station and implement networking supply, the laying of buried pipe network more than 180 kilometers, the existing pipeline gas residents more than 40000 subscribers, pipeline gas industrial and commercial users of more than 200 households. Increased in the past two years,

4、as the industrial and commercial users, especially some ceramics enterprises, guangdong enterprises producing not for intermittent supply of gas corporation put forward higher standards and requirements - to ensure the continuous and stable gas supply; But the reality is due to the new and old pipe

5、network to link, the original pipe network facilities maintenance, pipeline emergency handling of various objective reasons, must carry out stopping air part of gas pipe network, it will seriously affect the production of industrial and commercial users. In order to solve this contradiction, we must

23、进入过热段气化。为了满足排尽移动气化装置中的空气和使用结束排空移动气化器装置内残留的石油气，我们在气相出口处设置了排空阀。Mobile gasification device process as shown in figure 3, the liquid cylinder through A hose connected to the liquid inlet and liquid after a1 a2 or a3 into automatic switching valve, valve after the a4, a5 into the voltage regulator for a5

31、和紧急情况下的供气任务，每次都能保证乎稳、快捷、安全的供气。移动式气化装置在管网维修、有计划的停气时可以使用，在管网抢险、紧急停气时亦可以使用，另外，对于那些未连通通气管网、暂不能实行管道供气的用户可通过移动式气化装置进行临时供应，避免因施工临时期组站而造成的投资浪费。我们在使用移动式气化装置时，综合考虑气化能力及需求量，根据当时气温及液化气组分确定气化能力，根据用户情况及使用时间确定需求量。从使用过程中的实测数据表明，通过强制通风后，其供气能力达到设计能力的12倍，在空气温度为25、丙烷组分占50%时，每小时的气化能力已达到210Kgh，能够满足我市现有工业及商业用户用气的需要，如今后需求量
