Abstract

The invention relates to a stepped rotary shearing device for gas hydration separation. A rotating shaft is arranged at the center of a kettle bottom in a reaction kettle; a motor drives a motor shaftto rotate through a magnetic stirrer, and the motor shaft penetrates through the kettle bottom and is connected with the rotating shaft; the center of an upper cover of the reaction kettle is connected with a liquid injection pipe, and the liquid injection pipe at least extends into the middle of the reaction kettle in the axial direction; a rotor is connected with the rotating shaft, and a liquid distributor is arranged at the center of the rotor; an opening of a secondary dispersing cylinder faces upward, and the bottom of the secondary dispersing cylinder is connected with the rotor; the opening of a secondary fixing cylinder faces downward, and the bottom of the secondary fixing cylinder is connected with the liquid injection pipe; the double-layer fixing cylinder wall of the secondary fixing cylinder and the double-layer dispersing cylinder wall of the secondary dispersing cylinder are arranged at an interval in the radial direction. According to the device, liquid is driven to splash outwards through the rotation of the rotor, the contact area with introduced gas is effectively increased, the substance transmission efficiency between the two phases of a mixed gas-water solution in a hydration reaction process can be improved, and the gas content in a hydrate is greatly increased, so that a high-density solid gas hydrate is generated.

Description

technical field [0001] The invention relates to the technical field of gas hydration separation, in particular to a stepped rotary shearing device for gas hydration separation. Background technique [0002] Coal mine gas, as a kind of coal companion, is very rich in resources. If it is discharged into the atmosphere, it will waste resources and pollute the environment. However, the use of pipelines to store and transport coal mine gas is not only costly but also easy to cause pipeline blockage. [0003] The hydration separation method of coal mine gas can realize long-distance transportation and storage under normal pressure conditions, and has the advantages of economy, safety and effectiveness. The synthesis process of gas hydrate includes the dissolution of gas in water, the formation of crystal nuclei and the growth of hydrate. Under the existing conditions, there are problems in the process of gas hydrate synthesis, such as long hydrate induction time, reduced effecti...
