Helium is inert gas, usually colourless under pressure temperature, tasteless, nontoxic, non-combustible.It is that the mankind have found that critical-temperature is minimum
Substance, aobvious buff, is to be most difficult to liquefied gas when low pressure discharge, extremely inactive, cannot be burnt, also not fire-retardant, under normal pressure
Helium will not solidify when absolute zero.Derived from this class feature of helium, helium is very widely used on modern industry.Helium is in light
In fine manufacturing process, the protective gas that wire drawing stages use helium to heat and soften as optical wand utilizes the superconduction row and inertia of helium
The characteristic of gas, prevents optical wand from aoxidizing, and plays thermal conduction characteristic and saves energy consumption.In previous drawing optical fibers technique, this part helium
Gas largely all puts idle discharge, causes not can be recycled for helium, there is very big waste.The present invention returns such helium
It receives, is passing through subsequent purification, realizing and economize on resources, helium has obtained utilizing again.In existing process of industrialization, generally use
Be to be recycled with low pressure, and directly extracted using vacuum pump, not only influenced the production technology of producer in this way, but also cannot be guaranteed recycling helium
The purity of gas, recovering effect is undesirable, and helium recovery rate is low, and helium utilization rate is low, causes a large amount of wastes of helium.
Summary of the invention
The invention mainly solves the technical problem of providing a kind of fiber drawing furnace cooling tube helium recovery unit, using independently setting
The helium recovery device of meter and subsequent recovery process, it is low to improve prior art helium recovery rate, recovering effect it is undesirable and
