Description
(一)技术领域 (1) Technical field
本实用新型涉及一种压缩天然气调压供气装置，特别是一种压缩天然气多热源式调压供气装置。The utility model relates to a compressed natural gas pressure regulating gas supply device, in particular to a compressed natural gas multi-heat source type pressure regulating gas supply device.
(二)背景技术 (2) Background technology
天然气供应一般有两种方式：一种是管道供应，适用于大中城市中的固定场所；另一种是通过高压储气瓶将压缩天然气运输到气站，经加热、减压后供应到用户，适用于小城镇或分散的工业用户。在后一种方式中，压缩天然气是一种新的天然气存储方式，它的主要成分为甲烷(CH4)，经过脱硫、脱水、净化压缩到20MPa，使天然气体积减小，再将压缩天然气充装到特殊高压储气瓶中进行储存。用户使用压缩天然气时，一般是用特殊槽车将高压储气瓶运输到气站，进行加热、减压、调压、加臭，然后供给用户。该情况适合于没有管道燃气供应的较大的工矿企业和居民区。在该方式实施的加热环节中，目前提供热源的方法是循环热水，这就需用燃气热水炉、循环泵以及铺设管道等，不仅投资大、周期长，而且设备的适用性和灵活性差，特别是对于提供热源困难的用户，很难满足他们的供气要求。There are generally two ways to supply natural gas: one is pipeline supply, which is suitable for fixed places in large and medium-sized cities; the other is to transport compressed natural gas to gas stations through high-pressure gas storage cylinders, and supply them to users after heating and decompression , suitable for small towns or scattered industrial users. In the latter method, compressed natural gas is a new natural gas storage method. Its main component is methane (CH 4 ). Packed into special high-pressure cylinders for storage. When users use compressed natural gas, they generally use special tank trucks to transport high-pressure gas storage cylinders to gas stations for heating, decompression, pressure regulation, and odorization, and then supply them to users. This situation is suitable for larger industrial and mining enterprises and residential areas without pipeline gas supply. In the heating link implemented by this method, the current method of providing heat source is circulating hot water, which requires gas water heaters, circulating pumps and laying pipelines, etc., which not only requires large investment and long cycle, but also has poor applicability and flexibility of equipment. , especially for users who have difficulty in providing heat sources, it is difficult to meet their gas supply requirements.
(三)实用新型内容(3) Contents of utility model
