The Study Of One-dimensional Simulating Experimental Device Of Natural Gas Hydrates

The gas hydrate is a new type of energy which has brought widespread concerns around the world in recent years. The gas hydrate has been recognized as the optimal and the most promising new energy in the 21st century, which is because that the gas hydrates resources distribute widely in the global and have a huge quantity. Therefore, developping a new type of simulation experiment has a far-reaching significance for gas hydrate development and use.The basic properties, the basic structure, research history, as well as domestic and international simulation research methods of the gas hydrate are introdurced, meanwhile, the main contents of the subject, technical route and the organizational structure of thesis are interpretted .Secondly, the contents of one-dimensional gas hydrate simulating device, which has owned intellectual property rights, which is easy to use and testing data of which is accurate and reliable, is recommended in detail. The contents are those the design of temperature controlling method, and the haedware design, installation, software development and debugging of the gas hydrates simulating experimental device. In the design of the temperature controlling method, firstly the design target is analyzed. Meanwhile, in accordance with the characteristics of gas hydrates simulating experiment, the fuzzy control algorithm suiting for this device is designed. After the introduction of the fuzzy control theory, the design of the fuzzy controller on one-dimensional simulating device of gas hydrates is mainly researched. During the hardware design of the experimental devices, simulating principle and data acquisition principle on one-dimensional simulating device of gas hydrates are mainly introduced .Then the overall program of installation and the key to technology is given. The characteristics of data acquisition module and the data acquisition unit are interpreted detailly. The work flow of system is analized, and finally the hardware circuit design is proposed.The software design of one-dimensional gas hydrate simulating device is introduce in detailed, which include the overall design of software and the introduction of the main functional modules the Collection procedures and the communication procedures of the Balance are included.Finally, this device is tested through the experiment of the gas hydrate formation and decomposition. The collecting data certificates the stability and practicality of the one-dimensional gas hydrate simulating device.
