Description
Technical field
The invention belongs to a kind of cryogenic liquid storage device, and in particular to a kind of stifled liquid nitrogen container of deicing.
Background technology
The packing of liquid nitrogen is realized using by 100L from liquid nitrogen container is pressurized.Liquid nitrogen container is used as liquid nitrogen separation container
Frequency is very high, and the normal of it uses the essential condition for being Cryo Equipment day-to-day operation.
After the above-mentioned liquid nitrogen container packing liquid nitrogen from supercharging, the situation that liquid valve does not go out liquid nitrogen happens occasionally, and by observation, divides
Analysis, it is determined that moisture when being due to filling liquid nitrogen in air enters container, excessive velocities during topping up, the air in container is not complete
Full discharge, has condensed into ice, has plugged pipeline, caused ice to block up phenomenon, liquid nitrogen can not arranged at low temperature.
Ice is blocked up after the appearance of situation, and general solution is that liquid nitrogen container is left unused, and the liquid nitrogen allowed in container volatilizees naturally.And
This processing mode one is to waste liquid nitrogen；Two be that liquid nitrogen cycle of volatilizing completely is long, and influence liquid nitrogen container is normally used in turn.
The content of the invention
The present invention proposes that the purpose is to provide the liquid nitrogen appearance that a kind of deicing is stifled to solve the problem of prior art is present
Device.
The technical scheme is that：Receiving is provided with a kind of stifled liquid nitrogen container of deicing, including outer tank, the outer tank
