Problems solved by technology

In the existing technology, ordinary LNG storage tanks need to discharge a certain amount of BOG gas (a mixture of LNG gas and air) every day. The discharge of a large amount of BOG gas not only affects the operation efficiency and safety of the station, but also causes waste of resources and serious damage to the atmosphere. pollution, so it needs to be improved

Embodiment Construction

[0021] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0022] Such as Figure 1 to Figure 6 As shown, an integrated LNG skid-mounted refueling device includes a low-temperature storage tank body 1, a liquid outlet 2 is opened at one end of the low-temperature storage tank body 1, and a number of cooling fins are uniformly arranged in the low-temperature storage tank body 1 3.

[0023] The heat sink 3 is one of titanium alloy heat sink, nickel alloy heat sink, silver alloy heat sink, aluminum alloy heat sink, magnesium alloy heat sink, and copper alloy heat sink. The cooling fins 3 made of these materials have a better effect of heat transfer and heat dissipation.

[0024] A number of purge valves are arranged o...

Abstract

The invention relates to an integrated LNG skid-mounted gas filling device, comprising a low temperature storage tank body. One end of the low temperature storage tank body is provided with a liquid outlet; and a plurality of heat sinks are uniformly disposed in the low temperature storage tank body. The integrated LNG skid-mounted gas filling device is simple in structure and convenient for use. The lowest temperature in the storage tank can reach -196 DEG C. The integrated LNG skid-mounted gas filling device is safe and reliable, and can ensure that the gas is filled safely and reduce daily BOG gas emissions by 50-80%, thereby reducing pollution of the gas to the environment and greatly reducing cost.

Description

technical field [0001] The invention relates to the gas filling field of LNG gas filling stations, in particular to an integrated LNG skid-mounted gas filling device. Background technique [0002] LNG is the abbreviation of liquefied natural gas, which is the dehydration, dehydrocarbon, desulfurization and removal of CO 2 After purification treatment, it is liquefied at low temperature, and its main component is methane. The use of LNG can greatly reduce the transportation and storage costs of natural gas. Therefore, LNG fueled vehicles are one of the main directions of future vehicle development. [0003] As one of the main core components of the LNG filling station, the LNG storage tank, because the temperature of the gas in the storage tank is not the same in each part, the daily operation of the filling station system will inevitably increase the pressure of the storage tank. , must be vented when the safe limit of the storage tank pressure is reached. In the existin...
