Abstract

The invention relates to a method for synthesizing gas hydrates and a device thereof. The device mainly comprises a snake-shaped heat exchanger with vertical metal fins, a crystal growth pump and a steel gas hydrate reaction tank with heat-insulating coating. After the snake-shaped heat exchanger reduces the temperature inside the tank below a critical decomposition temperature, the crystal growth pump is started to allow the liquid water to pass through the bottom of a liquid refrigerant and enter the refrigerant phase and thereby enhancing the mixture of water and the refrigerant and simultaneously enhancing the heat exchange between the heat exchanger and reactants. At the beginning of gas hydrate synthesis, the crystal growth pump is shut down, so that the gas hydrate grows upward along the vertical metal fins in the refrigerant phase until the whole reactants are used up. The inventive device has the advantages of short induction time for hydrate synthesis, high density of synthetic gas hydrate, high energy-storage density, and good heat exchange performance.

Description

technical field [0001] The present invention relates to a method and device for generating gas hydrate, in particular to a method and device for generating gas hydrate by static rapid compaction which can be used for gas hydrate energy storage or gas storage. Background technique [0002] With the increasing popularity of refrigeration and air-conditioning devices, the "peak-to-valley difference" of electrical load caused by refrigeration and air-conditioning has become larger and larger, resulting in insufficient peak power and excessive valley power. 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 tariff 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 eutectic salt, but they all have unsatisfactory shortcomin...
