Embodiment Construction

[0021] The specific embodiments of the present invention will be described in detail below in conjunction with the technical solutions and accompanying drawings.

[0022] figure 1 Shown is the block diagram of the working principle of the low-energy gas hydrate synthesis device based on the thermoelectric effect. The working process is as follows: open the check valve b10, the high-pressure gas enters the hydrate synthesis tank 1 and the low-temperature liquid to form hydrate, and the thermoelectric module group in the process 2 absorbs heat and converts it into electrical energy, and drives the refrigeration device through the voltage stabilizer 4. After the hydrate is generated, it is suspended on the liquid surface, discharged from the hydrate output outlet, and enters the hydrate collection tank 16 through the transmission track 15 . When the liquid level is lower than the set value, the one-way valve a6 is opened, the water pump 5 is running, and liquid is supplied to th...

Abstract

The invention belongs to the technical field of hydrate application and provides a thermoelectric effect based low energy consumption gas hydrate synthesizer which comprises a thermoelectric conversion system, a hydrate synthesis kettle, a hydrate collection system, a liquid circulation system, a gas circulation system and a control system; high-pressure gas and low-temperature liquid produce hydrates in the hydrate synthesis kettle; and by utilizing the characteristic of the hydrate with the density smaller than that of water, the hydrates gather at the liquid level and automatically flow outto realize automatic collection. In the process, the thermoelectric conversion system timely absorbs the hydrates to produce released heat, so that on one hand, heat accumulation is avoided, the supercooling degree required for production of the hydrates is ensured, the hydrate production efficiency is further improved, the demand on cold energy input in the synthesis kettle is reduced at the same time, and the energy consumption is lowered; and on the other hand, according to the Seebeck effect, the thermoelectric conversion system converts the heat in the hydrate production process to the electric energy, and a refrigeration device can be driven, so that the refrigeration cost of the system is reduced, and the economy of the device is increased.

Description

technical field [0001] The invention belongs to the technical field of hydrate technology application and relates to a thermoelectric effect-based low-energy gas hydrate synthesis device. Background technique [0002] Gas hydrate is an enveloping crystal formed by the interaction between gas molecules and water molecules under certain high pressure and low temperature conditions. It is a non-stoichiometric clathrate solid compound. With the maturity of hydrate technology, gas hydrate has been widely used in many fields such as gas storage and transportation, gas mixture separation, and air-conditioning cold storage. In order to meet the needs of production and research, efficient and economical hydrate generation devices are urgently needed. The formation of hydrates is usually accompanied by the release of heat, which accumulates on the surface of hydrates, resulting in a decrease in the degree of subcooling and a reduction in the efficiency of hydrate formation.
