Problems solved by technology

Among them, the stirring method is the most direct and simple method, which can break the mass transfer limitation of the gas-liquid interface and effectively shorten the induction period by continuously updating the interface. However, the stirring efficiency gradually decreases with the continuous formation of natural gas hydrate, resulting in a

Abstract

The invention belongs to the technical field of production and application of natural gas hydrate, and particularly relates to a production-transportation integrated continuous reaction device for hydrate. The device structurally comprises an inner spiral reaction kettle, an outer spiral reaction kettle, a motor, a clamping ring and a magnetic transmission rod, wherein the inner spiral reaction kettle and the outer spiral reaction kettle are assembled in a nesting mode. A spraying method is introduced into the outer spiral reaction kettle, and micro-droplets are generated by utilizing the spraying method; through the buffering effect of external spiral blades, a gas-liquid contact area is increased, so the falling speed of the micro-droplets is reduced, the dispersion degree of the micro-droplets is increased, the conversion time of the micro-droplets is prolonged, the conversion time of hydrate is prolonged, and a conversion rate and a gas storage rate are increased; and the generatedhydrate is output through the conveying function of stirring rods and inner spiral blades, and secondary reinforced conversion is conducted in the process, so the conversion rate is further increased, the gas storage rate is increased, and continuous, rapid, efficient and continuous production and conveying of the natural gas hydrate are achieved.

Description

Technical field: [0001] The invention belongs to the technical field of natural gas hydrate production and application, and in particular relates to a hydrate production-transport integrated continuous reaction device. Background technique: [0002] After entering the modern society, the manufacturing industry has ushered in a golden stage of development, the economy is developing rapidly, and the energy consumption is increasing day by day, especially the high consumption of coal. In the long run, economic development will be limited by energy shortages. In order to avoid excessive dependence on energy imports and reduce environmental pollution, it is imperative to use abundant, clean and efficient energy to replace coal and oil in production on a large scale. [0003] Due to its excellent characteristics, natural gas has taken an increasing proportion in energy supply in recent years. Natural gas has problems such as huge regional differences in distribution and seasonal ...
