Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen production and hydrogenation protection, in particular to a lightning protection and antistatic system for a dock-type hydrogen production and hydrogenation integrated station. Background Art

[0002] my country attaches great importance to and supports the development of hydrogen energy. Since 2006, the State Council, the Ministry of Science and Technology, the National Development and Reform Commission, the Ministry of Industry and Information Technology, the Ministry of Commerce, the Intellectual Property Office, the National Energy Administration, the Ministry of Transport and other departments have successively issued a number of policies to support the development of hydrogen energy. By the end of August 2019, there were nearly 50 policies involving hydrogen energy and fuel cells. my country is the world's largest hydrogen producer, with an annual hydrogen production of about 33 million tons, of which about 12 million tons meet the industrial hydrogen quality standards. The domestic hydrogen energy industry is showing a positive development trend. It has initially mastered the main technologies and production processes such as hydrogen energy preparation, storage and transportation, hydrogenation, fuel cells and system integration, and has achieved small-scale demonstration applications of fuel cell vehicles in some regions. However, overall, my country's hydrogen energy industry is still in its early stages of development. Compared with the international advanced level, there are still problems and challenges such as weak industrial innovation capabilities, low technical equipment levels, lagging basic systems to support industrial development, and further exploration of industrial development patterns and development paths.

[0003] This project seizes the opportunity of my country's hydrogen energy development, gives full play to the advantages of the rich hydropower resources of the Gezhouba Power Station and the Three Gorges Power Station, builds hydrogen fuel-powered ships, uses them as the main application of hydrogen production and hydrogenation stations, and conducts water electrolysis hydrogenation demonstration project research in the Three Gorges Dam area. There are no relevant technical reports at home and abroad for reference. This project uses domestic water electrolysis technology to build hydrogen production and hydrogenation stations to produce green hydrogen, uses hydrogen fuel-powered ships as a consumption channel, opens up the entire hydrogen energy "hydrogen production, hydrogenation, hydrogen storage, and hydrogen use" industry chain, studies and masters the core technologies of the hydrogen energy industry chain, and also provides technical support for the "Hydrogenation of the Yangtze River" pilot.

[0004] The hydrogen involved in this project is a flammable gas. If it leaks into the environment and encounters an ignition source, it may cause a fire or explosion. The oxygen involved is an oxidizing gas that can support combustion. It can react violently or form an explosive mixture when in contact with reducing agents, organic matter, and metal powders. During its production, storage, and filling, careful measures and strict operating specifications must be formulated to reduce the generation of static electricity. However, the air is full of charged particles, and equipment will also accumulate static electricity during operation. Coupled with the influence of thunder and lightning weather, if lightning protection and static electricity elimination are not carried out in time, serious safety accidents will occur, affecting the safety of personnel and enterprises, and the accidents will also pollute the air.

[0005] For example, CN205777712U discloses a lightning protection and antistatic system for a chemical plant, including a plant gate (1) and a wall (11), wherein the plant gate (1) and the wall (11) surround a first workshop (21), a second workshop (22) and a third workshop (23), a matching workshop (31), a matching warehouse (32), a fourth workshop (33) and an unloading area (6) provided with an antistatic device and a lightning protection device. The utility model utilizes an antistatic device and a zero-potential grounding network for lightning protection provided in each plant, simplifies the laying and installation structure, makes monitoring more convenient, and improves the safety effect of production and transportation; the utility model only involves the production and transportation of gas in the chemical production area, does not involve the filling of gas, and the gas produced is not hydrogen and oxygen, so it has no reference and comparability compared with this project.
