Novel LNG gas-feeding integrated module device

Abstract

The invention discloses a novel LNG gas-feeding integrated module device, and belongs to the field of ship transportation. The device is designed according to the standards of ISO shipping containers, and comprises a liquefied natural gas gas-feeding device case and a case frame; wherein the liquefied natural gas gas-feeding device case comprises a liquefied natural gas storage tank, an operation valve case, a liquid transportation pipeline, a gasifying device, an emergency cut-off device, a gas flowmeter, a gas transportation pipeline, a pressure releasing pipe, and a vertical ladder; the case frame comprises a front end frame, a rear end frame, a upper side beam, a lower side bean, a diagonal brace, an upper diagonal member, a lower diagonal member, a bottom plate, and a bearer; the operation valve case comprises a liquid-phase operation pipeline, a gas-phase operation pipeline, a backup pipeline, and a control system, and the liquid-phase operation pipeline, gas-phase operation pipeline, backup pipeline, and control system are concentratedly arranged through low-temperature stainless steel pipes. The device solves the problems of difficult gas feeding for a diesel oil-LNG bi-fuel source ship. A gas-feeding station can utilize the integrated module device to safely butt-join a diesel oil-LNG bi-fuel source diesel engine, provide gas for the ship to be fueled, and control the gas volume. The transportation cost is reduced, and the transportation efficiency is improved.

Description

technical field [0001] The invention relates to a loading container for transporting liquefied natural gas, in particular to a novel LNG gas supply integrated module device, which belongs to the field of ship transportation. Background technique [0002] Existing inland ships are mainly diesel-powered, with high fuel consumption and large exhaust emissions, which not only increase transportation costs but also pollute the environment. Marine diesel-LNG hybrid power is to convert the existing diesel power into a hybrid power of diesel and natural gas, and the rate of natural gas replacing diesel can be as high as 60%-80%. Therefore, liquefied natural gas (LNG), as an economical, green, and safe new energy source, is gradually becoming well-known, and has become the first choice for future green energy recognized by the shipping industry. [0003] However, due to the limitation of refueling infrastructure, the problem of refueling ships has brought great troubles to shipping ...

AI Technical Summary

Problems solved by technology

[0003] However, due to the limitation of refueling infrastructure, the problem of refueling ships has brought great troubles to shipping companies, making ships using LNG fuel in reality still a minority

[0004] Based on the above reasons, the present invention provides an integrated modular device for supplying and refueling the engine of a transport ship, which solves the problem of "difficult refueling" for diesel-LNG dual-fuel powered ships, reduces transportation costs, and improves transportation efficiency
