Abstract

The invention relates to a low-temperature liquefied natural gas semitrailer tank truck, wherein a low-temperature liquefied natural gas tank is arranged on a trailer frame; a traction seat is arranged below before the low-temperature liquefied natural gas tank; the low-temperature liquefied natural gas tank is provided with an inner tank body and an outer tank body which are sleeved into each other; a gap is formed between the inner tank body and the outer tank body; the inner tank body is covered with a flexible alumium-foil heat preservation quilt; and circular ring-shaped profile reinforcing ribs are evenly distributed on the outer circumference of the barrel of the outer tank body. The reinforcing ribs on the barrel of the outer tank body of the low-temperature liquefied natural gas tank are circular ring-shaped profile reinforcing ribs which are evenly distributed and welded on the outer circumference of the barrel of the outer tank body; the operation of welding the circular ring-shaped profile reinforcing ribs on the outer circumference of the barrel of the outer tank body is convenient, and after welding, removing of welding burr at the inner outer circumference of the barrel of the outer tank body is convenient; after the circular ring-shaped profile reinforcing ribs are welded on the outer circumference of the barrel of the outer tank body, no welded junction is formed in the gap between the inner tank body and the outer tank body without influence on the vacuum degree of the gap between the inner tank body and the outer tank body; and the circular ring-shaped profile reinforcing ribs are evenly distributed and welded on the outer circumference of the barrel of the outer tank body, so that the capacity of the inner tank body can be increased.

Description

Technical field

[0001] The invention relates to a low-temperature liquefied natural gas semi-trailer tanker, in particular to a reinforcing rib for the outer tank of the low-temperature liquefied natural gas semi-trailer tanker. Background technique

[0002] Natural gas is an energy with good comprehensive performance. The volume of natural gas of the same quality is 600 times the volume of LNG. In order to facilitate transportation and storage, natural gas should be made into liquefied natural gas. Liquefied natural gas (LNG) is a liquefied natural gas made from gas natural gas under a certain pressure using cryogenic technology.

[0003] In road transportation, low-temperature LNG semi-trailer trucks are used to transport LNG. The low-temperature LNG semi-trailer truck has a trailer frame, wheels under the trailer frame, a low-temperature LNG tank on the trailer frame, a tractor seat under the front and bottom of the low-temperature LNG tank, and a low-temperature LNG tank has...
