Description
Technical field
The present invention relates to Thermal Equipment fields, more particularly to a kind of anti-icing stifled multistage drain formula liquefier.
Background technique
Cold header heat exchanger is the key equipment for low-temperature gas liquefaction, and increasing heat exchange area is the routine for improving liquefied fraction
Means.But for the gas such as nitrogen that fusing point and boiling point are closer to, increase heat exchange area makes it possible to gas and is too cold
Solid blocking heat exchanger channel is formed below to freezing point, to cause the sharply decline of heat exchange efficiency.If but not increasing
Heat exchange area, liquefied fraction are then difficult to improve again.
Summary of the invention
The purpose of the present invention is overcoming the shortcomings of prior art process, a kind of anti-icing stifled multistage drain formula liquefaction is provided
Device.
To achieve the above object, technical solution provided by the invention is as follows:
A kind of anti-icing stifled multistage drain formula liquefier, including heat exchanger and fluid reservoir, several ranks of the heat exchanger point
Section setting;It is equipped with small-sized fluid reservoir between two two heat exchangers and is used as hydrops;The bottom of the small-sized fluid reservoir is additionally provided with liquid trap
Lead to main fluid reservoir.
As a further improvement of the present invention, the main fluid reservoir is one, and each liquid trap is accessed in parallel way
Same main fluid reservoir.
As a further improvement of the present invention, the solenoid valve of control liquid outflow is respectively equipped on each liquid trap.
As a further improvement of the present invention, the small-sized fluid reservoir is hermetically sealed can, and gas in tank can be pushed back to described change
Hot device.
Further improvement of the present invention, the liquefier are suitable for liquefaction of nitrogen.
Compared with prior art, it takes out the advantage of the invention is that can in time separate condensed fluid and retains gas and continue liquid
Change, the stifled phenomenon of ice often occurs in when gas liquefaction that boiling point and fusing point can be effectively prevent to be closer to, substantially increases liquefaction
Efficiency.The present invention has the advantages that structure is simple, liquefaction efficiency is high, manufacture is easy to repair, economic cost is low, in low-temperature liquefaction and
It plays a significant role in field of heat exchange.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
In figure, 1 heat exchanger, 2 small-sized fluid reservoirs, 3 main fluid reservoirs, 4 solenoid valves, 5 liquid traps.
Specific embodiment
As shown in Figure 1, anti-icing stifled multistage drain formula liquefier of the invention, including multiple-stage heat exchanger 1, multiple small-sized storages
Flow container 2, main fluid reservoir 3, solenoid valve 4 and liquid trap 5.The heat exchanger 1 in each stage and multiple small-sized fluid reservoirs 2 are replaced by pipeline
It is sequentially connected, and outlet is arranged at the bottom of multiple small-sized fluid reservoirs 2, is linked into the same main storage by 5 pipeline of liquid trap in parallel
Flow container 3 makees last hydrops storage.Solenoid valve 4 is respectively arranged on being exported between the import of main fluid reservoir 3 of small-sized fluid reservoir 2
On liquid trap 5, the process of main fluid reservoir 3 is flowed into for controlling liquid from multiple small-sized fluid reservoirs 2;Small-sized fluid reservoir 2 is sealing
Structure can push back gas in tank to next heat exchanger 1.
Work implementation process of the invention is as follows:
Extraneous refrigeration machine is opened, gas (usually nitrogen) enters multiple-stage heat exchanger, gas to be liquefied from left end entrance
It is cooled to gas-liquid two-phase state after into first segment heat exchanger, is then pressed into the small-sized fluid reservoir bottom for having certain liq
Portion, liquid phase stay in tank body, and gas phase is picked out from tank body top, enter back into second segment heat exchanger and second small-sized holding vessel.Such as
This is repeatedly.After multiple small-sized fluid reservoirs run up to certain amount of liquid, the solenoid valve of bottom is opened, liquid flow is become owner of into liquid storage
In tank.
Finally, it is also noted that listed above is only a specific embodiment of the invention.Obviously, the present invention is gone back
Directly it can export or associate from present disclosure there are many deformation, those skilled in the art and is all
Deformation, is considered as protection scope of the present invention.
