Problems solved by technology

However, the mixed transportation method has the following problems: ①Hydrogen mixed in natural gas is easy to cause hydrogen damage to natural gas pipelines, which reduces the service life of natural gas pipelines and increases pipeline maintenance costs; ②The terminal equipment has restrictions on the proportion of hydrogen doping , for example, the proportion of hydrogen mixed with CNG internal combustion engines shall not be higher than 3%, and the direct mixed use of natural gas and hydrogen has the problem of poor adaptability to terminal equipment; ③ the energy consumption and difficulty of purifying hydrogen from natural gas are relatively high, and the cost is relatively high

Embodiment Construction

[0021] An example of the present invention will be described in detail below, and an example of the embodiment is shown in the drawings. The embodiments described below are illustrative of the invention, and is intended to be construed as limiting the invention.

[0022] like figure 1 and figure 2 As shown, the hydrogen delivery system according to an embodiment of the present invention includes a first conduit 1 and a second conduit 2.

[0023] The second conduit 2 is disposed within the first conduit 1, and the second conduit 2 extends in the extended direction of the first conduit 1, and the second conduit 2 is used to deliver hydrogen, the first conduit 1 and the second conduit 2 formation. The delivery space is used to deliver fluid resources in the delivery space.

[0024] Specifically, the second conduit 2 is inserted inside the first conduit 1, and the first conduit 1 and the second conduit 2 are generally extended in the left-right direction, the second conduit 2 from the...

Abstract

The invention discloses a hydrogen conveying system and a hydrogen conveying method. The hydrogen conveying system comprises a first pipeline and a second pipeline, the second pipeline is arranged in the first pipeline and extends in the extending direction of the first pipeline, the interior of the second pipeline is used for conveying hydrogen. a conveying space is formed between the first pipeline and the second pipeline, and the interior of the conveying space is used for conveying fluid resources. The hydrogen conveying method comprises the following steps of conveying the hydrogen in the second pipeline; conveying a fluid resource within the conveying space between the first pipeline and the second pipeline; and the hydrogen pressure in the second pipeline is equivalent to the pressure of the fluid resource in the conveying space. According to the hydrogen conveying system and the hydrogen conveying method, hydrogen damage caused by hydrogen to the pipeline can be avoided, purification is not needed, and the cost is low.

Description

Technical field [0001] The present invention relates to the field of hydrogen delivery techniques, and in particular, to a hydrogen delivery system and a hydrogen delivery method. Background technique [0002] Hydrogen is a clean energy, and has a wide source, renewable, etc. In recent years, the development of hydrogen has been emphasized. Due to the characteristics and demand of energy distribution in my country's East and Western parts, hydrogen's West-to-Air loss has a large demand. [0003] In the relevant technique, since the cost of the construction of special hydrogenation pipes is high, the conveying of hydrogen is mainly blended in natural gas and transported by natural gas pipelines. However, the blended delivery method has the following problems: 1 Mixed hydrogen in natural gas is easily caused by hydrogen damage of the natural gas pipeline, reducing the service life of the natural gas pipeline, increasing the maintenance cost of pipeline; 2 Terminal equipment is limi...
