Background art:
through long-term exploration and development, hydrate technology gradually shifts to research on application and rapid production of hydrates from inhibiting hydrate generation. Currently, scientists are paying attention to the application of hydrate technology in gas separation and storage, solution concentration and separation, carbon dioxide replacement and exploitation, seawater desalination, refrigeration and cold storage, disposal of toxic and harmful substances and the like. The fundamental reasons for hindering the technical development of the hydrate are that the hydrate is harsh in forming conditions, slow in growth speed and difficult to realize continuous and large-scale rapid production. The hydrate is usually generated on a gas-liquid contact surface firstly, and then is gathered and extended, so that the mass transfer characteristic in the hydrate generation process is determined by the liquid film mass transfer coefficient; hydrate formation is an exothermic reaction and the efficient removal of the heat of hydration determines the heat transfer characteristics during hydrate formation.
At present, the hydrate formation strengthening means mainly comprises a physical method: stirring, bubbling and spraying; the chemical method comprises the following steps: adding thermodynamic promoter and surfactant. A preparation device in a traditional hydrate generation system generally adopts a high-pressure reaction kettle, and a cooling device adopts a low-temperature water bath tank. The high-pressure reaction kettle mixes the reactants by a single stirring device, the stirring is insufficient, and the reaction time is long; hydrates are gathered on the blades and the wall surface and are difficult to flow; the water bath box controls the temperature outside the reaction kettle, and the reaction heat cannot be effectively removed; and the reaction kettle has small volume, and has a considerable amplification effect from the preparation in a laboratory to the industrial production, so the method is not suitable for the high-efficiency continuous production of the hydrate. The US patent (US180843) uses a fluidized bed apparatus for the preparation of natural gas hydrates, the reaction heat is carried away by excess gas, the effective removal of heat cannot be achieved, and the industrial production is difficult. The japanese patent (JP2005263825A) uses a jet type process equipment to produce hydrate, the jet device improves the gas-liquid mixing effect, but increases the system complexity, and the stirred tank reactor is not favorable for continuous production of hydrate. The efficient continuous preparation device of the natural gas hydrate disclosed in the Chinese patent 200910263068.8 comprises a low-temperature water tank provided with a low-temperature water bath, a gas-liquid mixer, a plurality of folding tube reactors, a hydrate separator and a hydrate storage tank; the low-temperature water tank is provided with an air inlet pipe, the air inlet pipe is connected with a gas-liquid mixer through the interior of the low-temperature water tank, and the low-temperature water tank is provided with a water outlet connected with the gas-liquid mixer; the gas-liquid mixer, the folding tube reactor, the hydrate separator and the hydrate storage tank are sequentially connected; the folding pipe type reactor is of a box body structure or a cylinder body structure, and a folding pipeline or a spiral pipeline connected in parallel is arranged inside the folding pipe type reactor; baffle plates are arranged among the pipelines outside the pipeline, fins are arranged outside the pipeline for enhancing heat exchange, and autorotation spiral buttons or starters are arranged in the pipeline; two ends of the folding pipe type reactor are respectively provided with a water distribution chamber and a water collection chamber; two ends of the folding pipeline or the spiral pipeline are respectively communicated with the water distribution chamber and the water collection chamber; hydrate slurry is generated by adopting a folding tube type reactor, and then the hydrate is generated by further cooling, so that the concentration of the slurry is difficult to control, and hydrate blockage is easily caused by the folding tube type reactor.
