Embodiment Construction

[0032] The present invention will be further described below in conjunction with drawings and embodiments.

[0033] figure 1 Shown is the block diagram of the working principle of the semi-continuous piston hydrate cake generating device. The working process is as follows: at the beginning of the experiment, connect the pipeline and check the air tightness

[0034] 1. The working process of the temperature control system is as follows: set the temperature of the air bath console to the experimental set value, and reduce the temperature of the reactor to the experimental temperature.

[0035] 2 The working process of the numerical control system is: after vacuuming, control the liquid source to inject quantitative liquid from the side of the reactor, and then control the high-pressure gas source to inject gas into the reactor, so that the pressure in the reactor reaches the experimental set value, that is, the quantitative gas. Set the rotation speed and rotation time of the r...

Abstract

The invention relates to a semi-continuous piston type hydrate cake generating device, and belongs to the field of hydrate technology applications. The semi-continuous piston type hydrate cake generating device comprises a reaction kettle, a temperature control system, a numerical control system and a data collection system. A piston is installed in the reaction kettle, and the piston which does reciprocating motion can compress generated hydrates to be in the shape of a round cake; the temperature control system can precisely control the temperature of an air-bath operation desk and then control the temperature in the reaction kettle; the data collection system can collect temperature and pressure signals in real time and perform real-time analysis; the numerical control system controls a liquid source and a high-pressure gas source to inject quantificational liquid and gas into the reaction kettle and enables the pressure of the reaction kettle to reach a set value; in addition, the numerical control system controls a rotation-shaft motor to enable the reaction kettle to clockwise and anticlockwise rotate for 180 degrees at a certain rate, and therefore a gas phase and a liquid phase are fully mixed to promote generation of the hydrates; furthermore, the numerical control system can control a telescopic rod and a rotary telescopic type disassembly head to be conveniently disassembled.

Description

technical field [0001] The invention relates to a semi-continuous piston type hydrate cake generating device, which belongs to the application field of hydrate technology. Background technique [0002] As natural gas resources play an increasingly important role in national production and life, accelerating the development of natural gas storage and transportation technologies has become the key to effectively utilizing natural gas resources. At present, the practical storage and transportation methods include: gaseous transportation (PNG) under pressure through pipelines and liquefaction of natural gas (LNG) using cryogenic technology. About 75% of the world's natural gas is currently transported by pipeline. Natural gas pipeline transportation technology is relatively mature, but the investment in pipeline construction is huge, accounting for about one-third of the investment in the entire natural gas industry. Natural gas liquefaction is currently the main means of ocea...
