Description
Technical field
The invention belongs to gas hydrate generation technique field, specifically a kind of reciprocal convertible generation uniform gas hydration
The experimental provision of thing.
Background technology
Gas hydrate be by gas molecule (such as methane, carbon dioxide, nitrogen, hydrogen sulfide) and water in uniform temperature and
The non-stoichiometric solid crystalline material generated under pressure (generally cryogenic high pressure).Gas hydrate is a kind of high density energy
Quantity of material, with technology of preparing condition is simple, stable performance, the features such as store safe.In recent years, as gas hydrate is studied
Go deep into, discovery carries out gas separation and accumulating and can become a kind of new and effective industrial technology using gas hydrate.
Routine prepares hydrate sample using simple water filling gas injection generating mode, and is usually taken from one or few
Number it is several point injection gas-liquids modes, gas-liquid in deposit distribution have very big randomness, cause hydrate generate with
It is in afterwards non-uniform Distribution state in deposit.
Under study for action, generation theorem property of the stirring to hydrate, the particularly shadow of induction time and gas-storing capacity are found
Sound is very big.At present existing stirring technique is internal mechanical stirring or magnetic agitation.During stirring, reaction vessel interior is placed with
Mechanical agitation is starched or magneton.All there is shortcoming in both modes：One is that the generation caking of gas-water interface hydrate can hinder bottom
The continuation of hydrate is generated, the hydrate block consolidation that mechanical agitation slurry or magneton also can be generated, it is impossible to is completed stirring mixing and is appointed
Business；Two is that in the transportation after hydrate is generated, mechanical agitation slurry or magneton are connected with hydrate, it is impossible to take out.
The content of the invention
It is an object of the invention to provide a kind of reciprocal convertible experimental provision for generating uniform gas hydrate, to generate
The gas hydrate of substantially uniformity.
The present invention is achieved through the following technical solutions：
A kind of reciprocal convertible experimental provision for generating uniform gas hydrate, including air supply unit, temperature control unit,
Reactor, reciprocal convertible agitating unit, exhaust unit and data acquisition process unit, the air supply unit include gas cylinder tank and
Intake valve, for injecting gas in reactor；The temperature control unit includes water bath with thermostatic control, and it is equipped with anti-for placing
The water leg of kettle is answered, for controlling the temperature of reactor；The exhaust unit includes vacuum pump and air bleeding valve, for discharging reaction
The gas of kettle；The data acquisition process unit includes temperature sensor, pressure transducer, data acquisition controller and calculating
Machine, the data acquisition controller passes through the temperature and pressure in temperature sensor and pressure transducer automatic measurement reactor,
And be sent to computer and processed；The reciprocal convertible agitating unit includes reciprocal convertible agitating device, described past
Multiple convertible agitating device can make reactor carry out the reciprocating of 180 degree to spin upside down.
Further, the reciprocal convertible agitating unit also includes mixing control platform, and it is right that the mixing control platform is used for
The speed of reciprocal convertible agitating device is adjusted.
Gas hydrate is generated experiment and is carried out using constant volume method.The reactor and gas supply line that will be equipped with question response water is taken out very
After sky, open air intake valve and be filled with question response gas；All valve ports are closed, start-up temperature control unit is stirred with back and forth convertible
Unit is mixed, hydrate formation is carried out.By data acquisition process may determine that the hydrate of system in reactor generate into
Exhibition.Question response is fully completed, and can take out reactor, carries out hydrate gas storage and transportation application.
Compared with prior art, experimental provision of the invention has the advantage that：
1. by reciprocal convertible agitating unit, make reactor carry out the reciprocating of 180 degree and spin upside down, use gravity to
Gas-liquid is sufficiently mixed, so as to realize generating complete and uniform gas hydrate, the efficiency of gas storage and transportation is improved；
2. the residual without mechanical agitation slurry or magneton in reaction vessel, reaction vessel can directly take out, carry out next
Step transport operation.
