Tube bundle type container for transporting high-pressure gas

Abstract

The invention discloses a tube bundle type container for transporting high-pressure gas. The technical problem that a traditional transportation trailer is small in transportation amount and low in transportation efficiency, and a composite material layer easily cracks in a loop mode in the long-term use process of a composite long tube. The tube bundle type container comprises a container body and a tube bundle type gas bottle set installed in the container body, wherein a plurality of tube bundle type gas cylinders which communicate with each other and are used for storing the high-pressuregas are integrated in the tube bundle type gas bottle set; and the container body is internally provided with a safety cabin and an operation cabin, the safety cabin is used for safely fixing the front end of the tube bundle type gas bottle set and installing a safety relief device, the operation cabin is used for safely fixing the rear end of the tube bundle type gas bottle set and communicatingand inflating and deflating the tube bundle type gas bottle in the tube bundle type gas bottle set, and the operation cabin is internally provided with a charging and deflation device connected with the tube bundle type gas bottle. According to the container, the 15 composite long tubes with the working pressure of 30 MPa and the outer diameter phi of 529 mm can be arranged in the container, the hydrogen transport amount is about 610 kg, and the gas transportation volume is increased by 80% or more.

Description

technical field [0001] The invention relates to a tube-bundle container for transporting high-pressure gas. Background technique [0002] With the popularization and development of hydrogen fuel cell vehicles, long-tube trailers play an increasingly important role in the transportation of high-pressure hydrogen. The long-tube trailer can not only transport high-pressure hydrogen, but also transport CNG, compressed oxygen, helium, nitrogen, and other special gases. The long-tube trailers usually referred to are divided into tube-bundle-type long-tube trailers and bundled-type long-tube trailers according to their structures, and tube-bundle long-tube trailers are the most widely used. [0003] The tube-bundle container on the existing tube-bundle long-tube trailer, due to the requirements of the road weight limit and vehicle design weight limit (domestic height limit of 4 meters, weight limit of 40 tons), the container with a nominal working pressure of 20MPa is fully loaded...
