Problems solved by technology
[0002] Some of the existing well washing and wax removal vehicles use fuel oil as the combustion medium, but the current liquefied natural gas reserves cannot realize the automatic and constant adjustment of the temperature in the system to ensure the safe and automatic operation of the system, but the fuel needs to be vaporized and burned, but the engine water cannot Provide enough heat for vaporization, so LNG storage becomes an important problem to be solved, reducing labor intensity and reducing safety hazards

A novel intelligent control liquefied natural gas storage system is characterized by comprising a storage tank, an injector head, a controller, a converter, a liquid level pin, a pressure sensor, a safety valve, a fluid filling connector, a fluid outlet valve and a flow via valve; and the liquid filling connector is connected with a gas filler, the fluid outlet valve is used for controlling fuel supply, the flow via valve is used for preventing a great amount of fuel from being leaked out when a supply pipeline is broken, the storage tank is used for containing the liquefied natural gas fuel,the fluid injector head is used for cooling, the controller is used for controlling all the valves and connected with control valves and the liquid level pin, the liquid level pin is connected with the pressure sensor through the converter, a safety valve for pressure relief is opened when pressure in the storage tank exceeds the value, the storage tank is of a dual-layer vacuum structure with aninner container and an outer wall, and a plurality of layers of thermal insulating materials are arranged between the inner container and the outer wall. The novel intelligent control liquefied natural gas storage system has the advantages and characteristics of being simple in structure, reasonable in design, capable of achieving intelligent control over storage, safe, reliable and easy to operate, reducing the requirement for skills of personnel, increasing the safety coefficient and the like.
Description
technical field [0001] The invention relates to a natural gas storage device for a well-washing and wax-removing vehicle used in oil recovery operations in the petroleum industry, and in particular provides a novel intelligent control liquefied natural gas storage system. Background technique [0002] Some of the existing well washing and wax removal vehicles use fuel oil as the combustion medium, but the current liquefied natural gas reserves cannot realize the automatic and constant adjustment of the temperature in the system to ensure the safe and automatic operation of the system, but the fuel needs to be vaporized and burned, but the engine water cannot Provide enough heat for vaporization, so LNG storage has become an important problem to be solved, reducing labor intensity and reducing safety hazards. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned existing technical problems, and to provide a novel intelligent ...
