Abstract

The invention provides a liquefied petroleum gas loading and unloading pry which comprises a gas path unit and a liquid path unit. A gas inlet of a booster device in the gas path unit communicates with an inlet end of the gas path unit, and a gas outlet of the booster device communicates with an outlet end of the gas path unit; the liquid path unit comprises a loading branch and an unloading branch which are connected in parallel; a first liquid loading valve, a loading gas-liquid separator, a loading mass flow meter and a second liquid loading valve are sequentially arranged on the loading branch; an inlet of the loading branch communicates with a second end opening of the liquid path unit and an outlet of the loading branch communicates with a first end opening of the liquid path unit; a first liquid unloading valve, an unloading gas-liquid separator, an unloading mass flow meter and a second liquid unloading valve are sequentially arranged on the unloading branch; and an inlet of the unloading branch communicates with the first end opening of the liquid path unit, and an outlet of the unloading branch communicates with the second end opening of the liquid path unit. When the liquefied petroleum gas loading and unloading pry is used for loading and unloading LPG, a great number of pipelines do not needed to be mounted on the site, work can be started by connecting corresponding inlet and outlet, and inner line connection is simple, so that mounting workload is reduced, working progress is quickened, and loading and unloading efficiency of LPG is greatly improved.

Description

Technical field [0001] The invention relates to a liquefied petroleum gas loading and unloading device, in particular to a liquefied petroleum gas loading and unloading skid. Background technique [0002] In recent years, with the strengthening of awareness of energy conservation and environmental protection, rising fuel prices, and the gradual maturity of LPG technology, LPG related industries have developed rapidly. At present, LPG gas supply projects and storage and distribution projects will involve the problem of LPG loading and unloading. Since multiple pipelines are required to be connected to achieve LPG loading and unloading respectively, a large number of pipelines need to be installed on site during LPG loading and unloading. Various pipelines are not only complicated in connection, but also occupy a large area, resulting in a large amount of installation during on-site operation, a long installation period, troublesome loading and unloading operations, delaying the wo...
