An intelligent control device for liquefied natural gas fishing vessel

Abstract

The invention belongs to the liquefied natural gas utilization control technical field, and concretely relates to an intelligent control device for a liquefied natural gas fishing vessel. An LNG pressure / temperature control module, an engine fuel supply monitoring module, an engine detection and safety protection module and a fishing vessel navigation module electrically connect and communicate with each other through information, and together form a detection control navigation system. An LNG storage tank, a -100 DEG C freezer, a -60 DEG C freezer, a -18 DEG C freezer and a cold seawater preparation bank electrically connect and communicate with each other through information, and are cooperated with each other to form a liquefied natural gas cold energy utilization system. All parts electrically connect with each other through information. Liquefied natural gas cold energy is utilized in an intelligent and highly efficient manner by taking economic aspects into consideration since use conditions of a liquefied natural gas fishing vessel are special. Intelligent and gradient utilization of liquefied natural gas cold energy can be effectively controlled, and economical and social effects of the liquefied natural gas fishing vessel are guaranteed. The intelligent control device has a simple structure and a user-friendly operation interface, functions safely and steadily, and is easy to popularize and apply.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of liquefied natural gas utilization control, and in particular relates to an intelligent control device for a liquefied natural gas fishing boat, which is aimed at a liquefied natural gas fishing boat and efficiently utilizes the cold energy of liquefied natural gas from an economic point of view. [0003] Background technique: [0004] In September 2011, my country's first fishing boat using diesel and LNG (liquefied natural gas) fuel was successfully tested. The Fishing Vessel Inspection Bureau signed a comprehensive cooperation agreement with CNOOC Gas and Power Group Co., Ltd. to promote the use of LNG fuel for fishing boats. Guangxi, a major fishery province, launched a fishing boat " The "Oil to Gas" project opened the curtain for my country's fishing boats to use LNG clean energy; in 2012, the Fishing Vessel Inspection Bureau put forward the exact "Fishing Vessel LNG Power Transformation Plan", ...
