Problems solved by technology

However, in actual operation, after hydrogen enters the reaction tank, it needs to gradually diffuse and transfer to the interior of the hydrogen storage alloy, and the hydrogen storage alloy reaction bed of the device is wrapped around each heat exchange pipe of the heat exchanger, so the diffusion of hydrogen The mass transfer needs to be gradually carried out from the two sections of the reaction bed to the inside, which affects the diffusion rate of hydrogen and reduces the purification efficiency of hydrogen

Abstract

The invention discloses a hydrogen purifying device with a herringbone structure, which comprises a reaction vessel connected with the inlet and exhaust pipes, and the inner chamber of the reaction vessel is provided with a herringbone structure connected with the inlet and exhaust pipes. Hydrogen pipelines are arranged in a shape, and the inner cavity of the reaction vessel is also provided with heat sinks arranged in a herringbone shape, and the hydrogen pipelines and heat sinks are arranged alternately. The invention adopts the hydrogen diffusion pipeline of the fishbone structure and the corresponding heat exchange inner wall, which greatly improves the heat exchange effect during hydrogen absorption and desorption, and significantly improves the hydrogen absorption and desorption rate of the hydrogen storage alloy. The hydrogen of the fishbone structure The pipeline and the inner wall can disperse the stress generated when the hydrogen storage alloy absorbs and releases hydrogen, enhance the pressure bearing strength of the device, and also prevent the hydrogen storage alloy powder from accumulating at the bottom of the device after a long period of use. Therefore, the device can greatly improve the purification efficiency of hydrogen in actual use, and it is also more guaranteed in terms of service life and safety.

Description

technical field [0001] The invention relates to purification equipment, in particular to a hydrogen purification device. Background technique [0002] As a clean, efficient, and sustainable secondary energy, hydrogen energy is an important carrier for building a clean energy-based multi-energy supply system in the future. The development and utilization of hydrogen energy has become an important direction of a new round of world energy technology transformation, and it is also a strategic commanding height for the future development of the automobile industry. Driven by the policy of non-regression of government subsidies in my country, the proton exchange membrane fuel cell vehicle industry has developed rapidly and has become a pioneer in the commercial application of hydrogen energy. With the continuous breakthrough of fuel cell application technology, the application market is becoming more and more mature, and the demand for hydrogen is also increasing rapidly. Howeve...
