Abstract

The invention discloses a loop type gas hydrate reaction device. The device comprises a loop, and a microbubble type gas injection unit, a visible window, a static mixer, a buffer tank and a circulating pump which are communicated through the loop, the microbubble type gas injection unit comprises a gas injection chamber, a gas column and a bubble generation chamber; the buffer tank comprises a feed port, a hydrate sampling port, a gas-liquid outlet and a water inlet; a stirring device is arranged in the buffer tank; the circulating pump is located at the downstream of the buffer tank, an inlet of the circulating pump is communicated with a water outlet of the buffer tank, and an outlet of the circulating pump is communicated with the loop. According to the device disclosed by the invention, intermittent gas injection and a continuous mixing enhancing effect of the static mixer can be realized by utilizing the microbubble type gas injection unit and the static mixer, so that gas and liquid phases continuously circulate, disperse and react in a loop, and hydrates are dynamically generated in the loop. Compared with a kettle type reaction device, the device disclosed by the invention is more beneficial to the generation of the gas hydrate in a loop, and the reaction rate is improved.

Description

technical field [0001] The invention belongs to the technical field of gas hydrate application, storage and transportation, and in particular relates to a loop-type gas hydrate reaction device and a reaction method. Background technique [0002] Hydrate is a clathrate crystal inclusion. Water molecules form cage crystals through hydrogen bonding, and gas molecules are surrounded in the crystal lattice. Hindered by factors such as low gas storage density, slow formation rate, and long induction time, the biggest technical obstacle facing the current hydrate application technology is how to increase the rate and efficiency of hydrate formation. In order to solve these problems, many studies have focused on promoting the formation of hydrates, such as increasing the growth rate of hydrates by stirring at a certain rate, but stirring may destroy the structure of hydrates, and the energy consumption is large, and the gas storage density of hydrates is low; Ultrasonic atomization...
