Hydrate generation and sample preparation reaction kettle component

Abstract

The invention discloses a reaction kettle component for hydrate generation and sample preparation. The reaction kettle component comprises a reaction kettle, a kettle cover, a pressure and temperaturemonitoring device and a frequency-adjustable rotating motor, wherein one side of the reaction kettle is provided with a gas inlet pipeline and a gas inlet valve, the other side of the reaction kettleis provided with a liquid inlet pipeline and a liquid inlet valve, small holes are densely distributed in the pipe wall of the gas inlet pipeline in the reaction kettle, nano titanium composite plating layers are plated on the inner and outer side surfaces of the reaction kettle, the pressure and temperature monitoring device comprises a pressure monitoring instrument and a temperature monitoringinstrument, the frequency-adjustable rotating motor comprises a positive and negative rotating motor capable of rotating positively and negatively and a motor frequency modulator connected with the positive and negative rotating motor, the reaction kettle is placed on a stainless steel bracket, the whole reaction kettle component is placed in a constant-temperature air bath with a programmable temperature control function, and a vacuum instrument is arranged on the reaction kettle. The reaction kettle component can effectively improve the reaction rate of the hydrate, and ensures the uniformity and compactness of the generated hydrate sample at the same time; and the reaction rate is high, the sample surface is smooth and the sample distribution is uniform.

Description

technical field [0001] The invention relates to the technical field of hydrate production and preparation, in particular to a reactor component for hydrate formation and sample preparation. Background technique [0002] Gas hydrate is a cage crystalline compound, different guest molecules such as CH 4 , CO 2 , N 2 , H 2 Gas and water can form different types of gas hydrates under the conditions of low temperature and high pressure. Using the cage structure of hydrates and the different conditions for the formation of hydrates by various guest molecules, hydrates can be applied in different industrial and technical fields. However, basic research on hydrates requires test analysis and characterization of hydrate samples, and the characterization of hydrate samples requires the use of relevant equipment to conduct comprehensive multi-scale test analysis on different samples. The sample requirements are relatively high, and the hydrate samples generated need to be dense an...

Problems solved by technology

[0003] At present, the common hydrate sample reaction devices are concentrated in the way of stirring in the tank, such as mechanical stirring, magnetic stirring, and top spraying, etc. These methods can effectively increase the contact surface between liquid and gas, and to a certain extent can promote the hydrate. generated, but there are certain disadvantages

For example, for the stirring method, when the hydrate formation rate is fast, the stirring will be stuck and stopped, and the existence of rotating blades and stirring bars will affect the compactness and uniformity of the hydrate sample; , in the initial stage, the spraying of liquid can promote the formation of hydrate, but the amount of spraying liquid is fixed, and when the liquid required for the reaction is sprayed, the promotion effect of top spraying basically disappears
