The invention discloses a hydrate formation strengthening device suitable for pipeline flow conditions, the device comprises a sequentially connected gas source, a first one-way gas valve, a flow distributor, a Venturi jet unit, and a tubular hydrate reactor In addition, it also includes a liquid storage tank, a one-way liquid valve, a saturated liquid tank, a ball valve and a high-pressure nozzle; the Venturi jet unit of the present invention combines the Laval nozzle with the Venturi jet, which can increase the initial velocity of the airflow , making full use of the energy of the gas, which is conducive to improving the operating efficiency of the Venturi jet, and at the same time, the design of the variable diameter tube is used in synergy with the material inlet and material outlet of the tubular hydrate reactor, which promotes the hydrate. generate.
Description
Technical field: [0001] The invention relates to the technical field of hydrate formation enhancement, in particular to a hydrate formation enhancement device suitable for pipeline flow conditions. Background technique: [0002] The excellent physical and chemical properties exhibited during the formation of gas hydrate make it show great potential in the fields of gas separation, seawater desalination, natural gas solidification storage and transportation. However, the prerequisite for the industrial application of these technologies is that hydrates can be generated efficiently and continuously. Based on this, continuous hydrate generation devices under pipeline flow conditions have been developed successively. However, according to the current experiment and operation results, although the continuous generation of hydrate has been realized in the form of pipe flow, the rate and efficiency of hydrate generation are not high. In order to fully generate hydrate in the pipe...
