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 low final gas storage rate; The spray method improves the gas-liquid mass transfer capacity by spraying and dispersing tiny droplets, which can greatly enhance the gas-liquid mixing effect and increase the conversion rate, but the accumulation of incompletely converted natural gas hydrate at the bottom of the reactor will hinder further conversion

Abstract

The invention belongs to the technical field of natural gas hydrate production and application, and specifically relates to a hydrate production-transportation integrated continuous reaction device. The main structure includes an inner spiral reactor, an outer spiral reactor, a motor, a clasp and a magnetic drive rod The inner spiral reactor and the outer spiral reactor are assembled in a nested form. The spray method is introduced into the outer spiral reactor, and the spray method is used to generate micro-droplets. Through the buffering effect of the outer spiral blades, the gas-liquid contact area is increased to slow down The falling speed of micro-droplets increases the degree of dispersion of micro-droplets, prolongs the conversion time of micro-droplets, increases the conversion time of hydrates, improves the conversion rate and gas storage rate, and uses the transportation of stirring rods and internal spiral blades The function is to output the generated hydrate, and carry out secondary intensified conversion in this process, which further increases the conversion rate, improves the gas storage rate, and realizes the continuous, rapid and efficient continuous production and transportation of natural gas hydrate.

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 ...
