A kind of anti-icing stifled multistage drain formula liquefier
Technical field
The utility model 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 utility model is to overcome the deficiencies of prior art process, provide a kind of anti-icing stifled multistage drain formula liquid
Change device.
To achieve the above object, the technical scheme that the utility model is provided 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.
The main fluid reservoir is one as a further improvement of the utility model, and each liquid trap is in parallel way
Access same main fluid reservoir.
The electromagnetism of control liquid outflow is respectively equipped on each liquid trap as a further improvement of the utility model,
Valve.
The small-sized fluid reservoir is hermetically sealed can as a further improvement of the utility model, gas in tank can be pushed back institute
State heat exchanger.
Further improvement of the utility model, the liquefier are suitable for liquefaction of nitrogen.
Compared with prior art, the utility model has the advantage of can in time by condensed fluid separate take out and retain gas after
, often there is the stifled phenomenon of ice in continuous liquefaction, when gas liquefaction that boiling point and fusing point can be effectively prevent to be closer to, substantially increase
Liquefaction efficiency.The utility model has the advantages that structure is simple, liquefaction efficiency is high, manufacture is easy to repair, economic cost is low, low
It plays a significant role in temperature liquefaction and field of heat exchange.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
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, the anti-icing stifled multistage drain formula liquefier of the utility model, including multiple-stage heat exchanger 1, Duo Ge little
Type fluid reservoir 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 pass through pipeline
Alternating is sequentially connected, and outlet is arranged at the bottom of multiple small-sized fluid reservoirs 2, is linked by 5 pipeline of liquid trap in parallel same
Main fluid reservoir 3 makees last hydrops storage.Solenoid valve 4 be respectively arranged on small-sized fluid reservoir 2 the import for being exported to main fluid reservoir 3 it
Between liquid trap 5 on, 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.
The work implementation process of the utility model 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 utility model.Obviously, this reality
With it is novel can also there are many deformation, those skilled in the art can directly be exported from content disclosed by the utility model or
All deformations associated, are considered as the protection scope of the utility model.
