However, in the actual use process, because the pipeline between the crane pipe and the spherical tank is closed by a manually operated valve, in the early stage of leakage, more liquid hydrocarbons will still leak due to the untimely closing of the valve, which is safe and reliable in use. lower

The invention discloses a liquid hydrocarbon loading and unloading system, and belongs to the technical field of liquid hydrocarbon storage or distribution in the petrochemical industry. The liquid hydrocarbon loading and unloading system comprises a spherical tank, a loading arm and a liquid path cut-off mechanism, the liquid path cut-off mechanism is provided with a liquid inlet and a liquid outlet, the liquid path cut-off mechanism is provided with an external pipe orifice, the external pipe orifice is used for introducing steam, and a slidable piston body is further arranged in the liquid path cut-off mechanism. The piston body is configured to close a flow path between the liquid inlet and the liquid outlet by means of air inlet pressure of the external pipe orifice; a liquid inlet of the liquid path cut-off mechanism is connected with the spherical tank through a pipeline, and a liquid outlet of the liquid path cut-off mechanism is connected with the crane pipe through a pipeline. The pipeline between the loading arm and the spherical tank is automatically cut off through the liquid path cut-off mechanism at the initial stage of leakage, so that the use safety of the liquid hydrocarbon loading and unloading system is improved.
Description
technical field [0001] The present invention relates to the technical field of storage or distribution of liquid hydrocarbons, in particular to a liquid hydrocarbon handling system. Background technique [0002] Liquid hydrocarbons refer to liquefied petroleum gas in the oil refining industry. It is gaseous at normal temperature and pressure and can only become liquid under pressure and cooling conditions. It is often called liquid hydrocarbons in the production process. Liquid hydrocarbons usually need to be transported by a tanker. After the tanker drives into a fixed parking space, the operator connects the crane pipe to the tanker to load and unload liquid hydrocarbons. In the actual operation process, due to the failure of the connection between the tanker and the crane pipe, it is easy to cause leakage of liquid hydrocarbons. After the leakage of liquid hydrocarbons, it will change from liquid to gaseous state and diffuse rapidly, and mix with air to form an explosive ...
