The invention relates to a visual dynamic simulating device for deposition in a gas
hydrate pipeline, which is used for simulating the generation, the transportation and the deposition of gas
hydrate in high-pressure high-speed air flow and can be used for summarizing the high-speed motion characteristic, the transportation mechanism and the deposition rule of a pipeline gas-
solid phase. The invention has the technical schemes that: the top end of a low-pressure gas
storage tank is provided with a temperature sensor and a
pressure sensor, the outlet end of the low-pressure gas
storage tank is connected with a high-pressure gas pump and then is connected with a high-pressure gas
storage tank, and the top end of the high-pressure gas storage tank is provided with a
pressure sensor; the outlet end of a
liquid storage tank is connected with a
metering pump, and the upper end of a gas-liquid separator is connected with a
vacuum pump and a
tail gas treating device; the top end of a high-pressure
reaction tube is connected with an outlet electrical heating insulation pipeline, and the bottom end of the high-pressure
reaction tube is provided with a
pressure sensor and an inlet electrical heating insulation pipeline; and a
data acquisition system is formed by a
data acquisition card, a computer, a cold
light source and a high-speed camera, and a pipeline temperature
attitude control system is additionally arranged. According to the visual dynamic simulating device disclosed by the invention, the
generation process, the transportation process and the
deposition process of the gas
hydrate in the high-pressure high-speed air flow can be really simulated, and the visual dynamic simulating device is used for evaluating a gas hydrate inhibitor.
