Description

Technical Field

[0001] The invention relates to the technical field of organic liquid hydrogen storage, in particular to an intelligent control system for organic liquid hydrogen storage. Background Art

[0002] Organic liquid hydrogen storage technology refers to the storage of hydrogen through the reversible reaction and hydrogenation reaction of unsaturated liquid organic matter such as certain olefins, alkynes or aromatic hydrocarbons and hydrogen, and the release of hydrogen through the dehydrogenation reaction. The mass hydrogen storage density is 5%-10%, and the hydrogen storage capacity is large. The hydrogen storage material is liquid organic matter, which can be transported at room temperature and pressure, which is convenient and safe. In the process of organic liquid hydrogen storage, multiple control modules such as hydrogenation, transportation, and dehydrogenation need to work in coordination. Therefore, the organic liquid hydrogen storage intelligent control system is required to carry out comprehensive control and coordination to improve efficiency.

[0003] An organic liquid in-station hydrogenation station and its control method disclosed in Chinese patent CN116697272A stores hydrogen in a first hydrogen storage tank group and a second hydrogen storage tank group, so that when a car is refueled with hydrogen, the vehicle can be refueled in stages and in sequence, thereby avoiding excessive hydrogen refueling at one time and improving safety during refueling. However, the organic liquid in-station hydrogenation station and its control method mainly control the hydrogenation process, and cannot perform overall control and coordination for the organic liquid hydrogen storage process of hydrogenation, transportation and dehydrogenation, which is likely to affect the hydrogen storage efficiency and cause losses and increased manpower investment. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide an intelligent control system for organic liquid hydrogen storage, which effectively solves the deficiencies of the prior art.

[0005] The purpose of the present invention is achieved through the following technical solutions: an intelligent control system for organic liquid hydrogen storage, comprising the following modules and steps:

[0006] 1) The hydrogen delivery control module controls the hydrogen delivery and hydrogenation process of the organic liquid hydrogen storage equipment;

[0007] 2) During the hydrogenation process, the pressure detection control module and the temperature detection control module perform real-time detection and monitoring of the pressure and temperature of the organic liquid hydrogen storage equipment;

[0008] 3) During the hydrogenation process, the safety detection module detects and monitors the operating environment of the organic liquid hydrogen storage equipment and controls the inlet and outlet valves;

[0009] 4) During the hydrogenation process, the organic liquid saturation detection module determines the saturation of the hydrogenated organic liquid based on the quality and color of the organic liquid, and controls the progress of hydrogenation;

[0010] 5) When the hydrogen storage organic liquid is transported and dehydrogenated, the temperature and pressure are controlled, and the dehydrogenation catalyst is automatically replaced and regenerated and recycled.

[0011] Optionally, the hydrogen delivery control module in step 1) controls the internal temperature and pressure of the organic liquid hydrogen storage equipment to reach rated values, and a hydrogen sensing device is set in the delivery pipeline, and a liquid level sensor is set in the organic liquid hydrogenation equipment.

[0012] The above technical solution is adopted: by respectively arranging a hydrogen sensing device and a liquid level sensor on the transmission pipeline and the organic liquid hydrogenation equipment, the organic liquid addition situation and the hydrogen transmission situation are monitored, so that the hydrogen transmission control module can detect and control the hydrogenation process of the organic liquid hydrogenation equipment.

[0013] Optionally, the hydrogen delivery control module in step 1) controls the filling of unsaturated organic liquid into the organic liquid hydrogenation equipment, and the liquid level height is sensed and controlled by a liquid level sensor.
