Embodiment Construction

[0028] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0029] As shown in Figures 1 and 2, the present invention mainly includes a water bath 1, a reaction cylinder 2, a temperature sensor data line 3, a pressure sensor data line 4, a camera 5, a computer 6, and a data acquisition instrument 7. Among them, the core component reaction cylinder is mainly composed of quartz glass cylinder 8, stirring motor 9, magnetic stirrer 10, upper flange end cover 11, lower flange end cover 12, fastening bolts 13, sealing gasket 14, temperature sensor 15, pressure sensor 16.

[0030]Four fastening bolt mounting threaded holes 17 (shown in FIGS. 3 and 4 ) are respectively provided around the outer edges of the upper flange end cover 11 and the lower flange end cover 12 . The two ends of the quartz glass cylinder 8 are respectively embedded in the grooves of the upper and lower flange end covers 11 and 12, a...

Abstract

The present invention relates to a visualized phase equilibrium experimental device of freezing medium hydrate for coldness accumulation and an application of the same, comprising a water bath, a reaction tank, a camera, a computer, a data collector, characterized in that the reaction tank is composed of a quartz glass tank, a mixing electric motor, a magnetic stirrer, an upper flange end cap, a lower flange end cap, a temperature sensor and a pressure sensor; the application steps are: 1. producing hydrate; 2. measuring the phase equilibrium parameter of the freezing medium hydrant. This invention is exceedingly convenient to observe the formation process of gas hydrate under a defined temperature condition by a static method or a magnetically stirring crystallizing method; the gas hydrate produced in the process is exceedingly compact and of good heat exchanging performance; the invention is a visualized research apparatus that is capable of measuring the phase equilibrium parameter of freezing medium hydrates (comprising polynary ingredient systems and nanometre liquids) with an observation method and constant-volume method.

Description

technical field [0001] The invention relates to a hydrate visualized phase equilibrium experimental device, in particular to a visual research experimental device for observing the complete hydrate formation of refrigerant hydrate in a static method or a magnetic stirring crystallization method. Background technique [0002] With the increasing popularity of refrigeration and air-conditioning devices, the "peak-valley difference" of electrical loads caused by refrigeration and air-conditioning is getting larger and larger, resulting in insufficient power at peak times and excess power at valleys. In order to shift peaks and fill valleys and improve the power generation efficiency of power plants, power departments in most regions of my country have formulated time-of-use electricity price policies to encourage users to adopt cold storage air-conditioning technology. At present, the cold storage working fluids used in cold storage air conditioners are mainly water, ice and eu...
