Problems solved by technology

The main problems are that the redundancy of preparation equipment is relatively complicated, the efficiency of hydrate formation is not high, and the output is small.
For example, the devices used in the experimental testing and research of hydrate slurry mostly use stirring and shaking, which consumes a lot of energy.

Embodiment Construction

[0018] The specific embodiments of the present invention will be described in detail below in conjunction with the technical solutions and accompanying drawings.

[0019] Such as figure 2 As shown, according to the device structure connection, using the device to carry out the continuous gas hydrate slurry synthesis method of gas throttling technology, the steps are as follows:

[0020] (1) Water injection-temperature control: the liquid inlet pump 2 is running, the one-way check valve 3 is automatically opened, the solution flows from the solution tank 1 into the π-type hydrate reactor, and the liquid on the left side of the π-type hydrate reactor reaches a certain height , that is, it will flow to the right side of the π-type hydrate reactor. Once the liquid level sensor 15 detects that the liquid height on the right side of the π-type hydrate reactor is greater than the set value, the liquid inlet pump 2 will stop working immediately, and the one-way check valve 3 automat...

Abstract

The invention provides a continuous type gas hydrate slurry synthesis method and device based on a gas throttling technology, and belongs to the field of hydrate technology application. The device comprises a water injection-temperature control part, a gas injection-hydrate continuous production part and a hydrate slurry recycling part. The gas injection-hydrate continuous production part comprises a gas intake system and a circulation system. After gas is throttled and expanded, the gas goes into a reactor, an instantaneous low temperature is obtained, and a hydrate is promoted to be rapidly produced. With use of a characteristic that the density of the gas hydrate is lower than that of water, after hydrate particles float upward, the hydrate particles automatically flow out of the reactor, so as to realize continuous production of the hydrate. A solution obtained after the hydrate slurry is filtered can flow back into the reactor through circulation, and thus the solution is reused. The pi-type hydrate reactor is novel and simple in design, and is conducive to collection of the hydrate; the preparation method is easy to operate, and the hydrate slurry producing efficiency and output capacity are further improved. The synthesis method and device are flexible in design, and a plurality of researches on synthesis of the gas hydrate also can be carried out.

Description

technical field [0001] The invention belongs to the application field of hydrate technology, and relates to a continuous gas hydrate slurry synthesis method and device based on gas throttling technology. Background technique [0002] Hydrate technology has developed rapidly in recent years. It has potential application value in the fields of energy storage, separation, and cold storage. It is urgent to develop continuous and efficient hydrate generation technology and devices. Take the natural gas hydrate storage and transportation technology as an example. This technology converts natural gas into hydrate slurry for storage and transportation. Compared with traditional storage and transportation methods such as natural gas compression, liquefaction, and pipeline transportation, hydrate slurry storage and transportation technology has more advantages. [0003] Compared with the storage and transportation cost of natural gas, the storage and transportation of hydrate slurry ...
