Visual system and method for gas hydrate cold storage/gas storage

Abstract

The invention relates to a visual device system of cool storage / gas storage for gas hydrate, which comprises a high pressure reaction kettle, a low temperature and constant temperature bath, a steady pressure and air intake system, a video monitoring system, a liquid inlet, a gas inlet, and an electronic endoscope, wherein, the end cover of the high pressure reaction kettle is provided with a temperature sensor and a pressure sensor, a permanent magnet stirring motor is fixedly arranged on the end cover of the reaction kettle in the middle of the reaction kettle and with the lower end is connected with a mixing blade. The air inlet is externally connected with the steady pressure and air intake system, signal data is input into the video monitoring system and the whole high pressure reaction kettle is positioned into the low temperature and constant temperature bath in order to realize working temperature. The design of the visual structure of the system can observe and collect reaction process images in real time; a magnetic coupling and stirring system is adopted to solve the problem of high pressure rotation sealing, and the operation is reliable without noise; the mode of adding a surfactant combined with mechanical stirring can greatly improve the generation rate of hydrate and cool storage / gas storage density.

Description

technical field [0001] The invention relates to a preparation technology of gas hydrate, in particular to a device and method for rapid generation of carbon dioxide gas hydrate. Background technique [0002] Energy and environmental issues are one of the focuses of international attention today. On February 16, 2005, the "Kyoto Protocol" came into force, marking the beginning of a new stage for the global response to greenhouse gas emissions to be implemented. my country CO 2 The emission situation is extremely severe. From 1990 to 2001, the net increase of carbon dioxide emissions was 823 million tons, ranking second in the world. According to the forecast of the International Energy Agency: China may surpass the United States in 2009 and become the world's CO2 2 The largest emitter of greenhouse gases, reaching 5.2 billion tons of carbon dioxide equivalent. Therefore, effective measures should be taken to control CO in thermal power plants 2 Emissions are of great sig...
