Problems solved by technology

However, most of the current observation methods for interfacial nanobubbles under natural gas hydrate decomposition conditions are based on the adsorption of bulk nanobubbles in the decomposition liquid on the observation substrate to form interfacial nanobubbles. The properties of the substrate have a relatively large impact on the observation results. big impact

Abstract

The invention discloses a generation device and an observation method for interface nanobubbles.The device comprises a reaction kettle composed of a kettle body and a kettle cover, a base is arranged in the reaction kettle, a liquid tank is arranged on the base, a placement bottom sheet is arranged in the liquid tank, and a bubble forming substrate is arranged on the placement bottom sheet. By adopting the device, the detachable liquid tank is arranged in the reaction kettle, and then the bubble forming substrate is arranged in the liquid tank, so that in-situ generation of the interface nanobubbles is realized, and compared with a generation mode of transferring decomposition liquid to a hydrophobic substrate, a bubble nucleation mode is consistent with a process of actually decomposing natural gas hydrate to form the interface nanobubbles, the mode is close to objective conditions of natural gas hydrate depressurization decomposition and interface nanobubble formation in an actual reservoir, meanwhile, the influence of substrate properties on experimental results is reduced, and the reliability of observation results is ensured.

Description

technical field [0001] The invention relates to the technical field of generation of interface nano-bubbles associated with the decomposition of natural gas hydrate, in particular to a device and an observation method for generating interface nano-bubbles. Background technique [0002] Natural gas hydrate has the advantages of cleanness, high combustion calorific value, and large resource reserves, and is considered to be an alternative clean energy with great potential. The decomposition of gas hydrate will produce a large number of nanobubbles. Due to its special physical and chemical properties, the impact of the accumulation of nanobubbles in reservoirs on the development of gas hydrate resources and safe production has aroused academic concern. [0003] Studying the morphology, distribution and evolution of interfacial nanobubbles based on indoor experimental observation methods is of great significance for revealing the potential impact of nanobubbles and guiding the c...
