Embodiment Construction

[0034] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0035] A liquid hydrogen vaporization and self-pressurization device, including a liquid hydrogen vaporizer, the liquid hydrogen vaporizer is provided with a hydrogen output pipeline 3 and a hydrogen output control valve 4 connected thereto, a hydrogen safety control valve 5, and a hydrogen pressure detector 7 and a liquid hydrogen filling pipeline 8; the liquid hydrogen vaporizer is set as a high-pressure liquid hydrogen vaporization device 1, and its working pressure is 10MPa to 200MPa.

[0036] Vaporizer is a kind of equipment often used in industrial production. Cryogenic liquid vaporizers, including liquid nitrogen, liquid hydrogen, liquid helium, and liquid oxygen vaporizers, have long been a mature technology and have been applied in many fields, especially LNG vaporizers, which have been widely used. The use of pressure vessels is extre...

Abstract

The invention relates to a liquid hydrogen vaporization device, and specifically relates to a liquid hydrogen vaporization and self-pressurizing device. The liquid hydrogen vaporization and self-pressurizing device is used in the process of vaporizing liquid hydrogen into gasified hydrogen through an evapourizer and increasing the pressure of the hydrogen to form high-pressure hydrogen. When applied to the hydrogen energy field, the liquid hydrogen vaporization and self-pressurizing device can be specifically applied in hydrogen refueling stations adopting vaporization and pressure increasingof transported liquid hydrogen. When the high-pressure liquid hydrogen vaporization device is used for vaporizing the liquid hydrogen and achieving self-pressurizing, the pressure ranges from 10MPa to200MPa, a hydrogen compressor is not needed, and energy consumption is reduced. The invention further relates to three ways of filling the liquid hydrogen into the high-pressure liquid hydrogen vaporization device. In the two ways, pressure difference squeezing is adopted, and the liquid hydrogen in a high-pressure liquid hydrogen storage tank is conveyed into the high-pressure liquid hydrogen vaporization device; in the other way, the liquid hydrogen is conveyed to the high-pressure liquid hydrogen vaporization device through a liquid hydrogen high pressure pump. Cold energy of the liquid hydrogen is fully utilized by the liquid hydrogen vaporization and self-pressurizing device. Compared with prior equipment, the liquid hydrogen vaporization and self-pressurizing device can work withoutthe hydrogen compressor in the liquid hydrogen vaporizing and self-pressurizing process, and energy consumption is reduced obviously.

Description

technical field [0001] The invention relates to a liquid hydrogen vaporization device, in particular to a liquid hydrogen vaporization and self-pressurization device, which is used in the process of vaporizing liquid hydrogen into gas hydrogen through a vaporizer and requiring pressurization of hydrogen gas into high-pressure hydrogen gas. In the field of hydrogen energy, it can be specifically used in hydrogen refueling stations that use liquid hydrogen as a transportation method for vaporization and pressurization at hydrogen refueling stations. Background technique [0002] In the field of hydrogen application, because the density of liquid hydrogen is higher than that of high-pressure gas hydrogen, the transportation cost of liquid hydrogen is only one-fifth of that of gas hydrogen. Therefore, there is a situation of storage and transportation of hydrogen through liquid hydrogen storage, and this is the future development trend. Fuel cell vehicles are one of the main di...
