Injection-type reactor for preparing gas hydrates

Abstract

The invention relates to an injection-type reactor, in particular an injection-type reactor for preparing gas hydrates, which comprises a nozzle, an entrainment chamber, a throat tube, a diffusion tube, a pin valve mounted at the nozzle and a flow controller mounted at the tail end of the throat tube. A visualized window is arranged at the diffusion tube, the reactor is provided with a reaction water inlet, a gas inlet, a gas valve, a valve, a gas-liquid outlet, a temperature sensor and a pressure sensor; the pin valve adjusts the area of the nozzle and further controls the intake amount of reaction water, and the flow controller can be replaced by another one with different apertures to change the drop size after injection. The injection-type reactor for preparing the gas hydrates enables the gas to contact and mix with the reaction water and then be injected and atomized at a high speed so as to increase the contact area between the gas and fogdrops, shorten the induction time of a hydration reaction, greatly improve the generation rate of the gas hydrates and realize the high-efficiency rapid generation of the gas hydrates, thereby being a novel high-efficiency reactor for preparing the gas hydrates.

Description

technical field [0001] The invention relates to a gas-liquid dispersion device for synthesizing gas hydrate, in particular to a spray reactor for preparing gas hydrate. Background technique [0002] Gas hydrate is a kind of cage-type enveloping crystal formed by certain gases (or volatile liquids) and water under low temperature and high pressure conditions. Different gases require different temperature and pressure conditions to form gas hydrates, and the types of gas hydrates formed are also different. Gas hydrates have the characteristics of large gas storage capacity, convenient transportation, and safe use. However, the technology for synthesizing gas hydrates is not yet mature, especially for gases that are difficult to form hydrates. The temperature and pressure conditions are not easy to control, and the hydration rate is also very slow. It is difficult to improve, so the application of this technology urgently needs a device for efficiently producing gas hydrate. ...

AI Technical Summary

Problems solved by technology

[0004] However, the above methods have disadvantages: ①The contact area between gas and water is very limited, which greatly affects the formation rate of gas hydrate; ②The synthesis of gas hydrate is not continuous, and the continuous generation of hydrate prevents the gas from hydrate The diffusion increases the blowing power and stirring power, which is not recommended economically; ③The thermal effect produced during mechanical stirring will inevitably affect the hydration conditions
