Description

一种回收LNG槽车BOG的撬装式液化装置
技术领域
本发明属于液化天然气运输技术领域，特别涉及一种回收LNG槽车BOG的撬装式液化装置。
背景技术
目前，液化天然气是一种清洁能源，其排放远低于煤炭、石油。近年来，我国大力发展LNG应用。主要的应用领域有发电、运输、化工、能源。LNG的一个重要运输方式是通过LNG槽车进行运输。由于LNG产地往往距离应用市场比较远，LNG槽车需要长距离运输。
LNG槽车不能完全消除环境向LNG的传热，运输过程中不可避免产生BOG(Boil ofgas)。另外，在对加气站充装LNG过程中，需要对LNG槽车进行增压，也会产生大量的BOG。这些BOG往往采用放空措施，一方面造成能源浪费，另一方面造成环境污染。
因此，现在亟需一种回收LNG槽车BOG的撬装式液化装置，能够实现BOG的回收，同时避免造成能源浪费和环境污染。
发明内容
本发明提出一种回收LNG槽车BOG的撬装式液化装置，解决了现有技术中BOG放空处理时造成能源浪费和环境污染的问题。
本发明的技术方案是这样实现的：回收LNG槽车BOG的撬装式液化装置，包括LNG槽车，LNG槽车上设置有LNG储罐，LNG储罐通过管道连通有压缩机，进入压缩机的BOG与压缩机排出的BOG通过回热器进行换热，LNG储罐通过至少2根管道连通有绝热容器，绝热容器内安装设置有制冷机的蒸发器。
作为一种优选的实施方式，LNG储罐、LNG槽车、制冷机、压缩机、绝热容器、管道安装在可整体移动的撬装式基座上。
附图说明
图1为本发明回收LNG槽车BOG的撬装式液化装置的结构示意图。
