The specific embodiment
Below in conjunction with accompanying drawing the utility model preferred embodiment is elaborated:
Deuterium nitrogen blending device as shown in Figure 1, it is suitable for scene that optical fiber makes and uses, and comprises optical fiber processing jar 5, the surge tank 4, the gas mixing device 3 that is connected with surge tank 4 phase pipelines and the liquid nitrogen storage tank 1 that is connected with gas mixing device 3 phase pipelines that connect of pipeline and deuterium air-capacitor receive bottles 2 mutually with optical fiber processing jar 5.Particularly, liquid nitrogen storage tank 1 is connected with gas mixing device 3 by pipeline 11, the deuterium air-capacitor is received bottle 2 and is connected with gas mixing device 3 by pipeline 21, on the gas mixing device 3 with pipeline 11 junctions with and be provided with control valve and flowmeter (not shown) with pipeline 21 junctions, to be used for controlling respectively the nitrogen that inputs to the gas mixing device and the amount of deuterium gas, make deuterium nitrogen mixed gas in the gas mixing device 3 reach the concentration of setting.
Gas mixing device 3 is connected with surge tank 4 by pipeline 31, the gaseous mixture of surge tank 4 storage setting pressures.Surge tank 4 is provided with deuterium gas concentration analyzer 6, by this analyzer 6, can measure the concentration of deuterium gas in the surge tank 4.
Optical fiber processing jar 5 has three pipeline connection ports, and first pipeline connection port is connected with liquid nitrogen storage tank 1 by pipeline 51, forms nitrogen and is blown into passage; Second pipeline connection port is connected with surge tank 4 by pipeline 52, forms gaseous mixture and is blown into passage; The 3rd pipeline connection port still is connected with surge tank 4 by pipeline 53, forms gaseous mixture recovery approach 7.Also be provided with vavuum pump and vacuum display list (not shown) in the optical fiber processing jar 5, before carrying out optical fiber processing, need optical fiber processing jar 5 is vacuumized.
The recyclable deuterium nitrogen of present embodiment blending device is mainly used in optical fiber and makes the scene, will describe gas mixing and recycling process below:
The optical fiber that at first will draw moulding is positioned over sealing locking in the optical fiber processing jar 5, the vavuum pump that starts optical fiber processing jar 5 earlier vacuumizes tank body, after the reading of vacuum display list reaches technological requirement, charge into nitrogen by pipeline 51 to the pure nitrogen gas of optical fiber processing jar 5 inlet and purge, so circulate and take out vacuum again one time after three times;
Then, open by-pass valve control and flowmeter that nitrogen and deuterium gas are supplied with simultaneously, nitrogen is transferred to variable proportioning gas mixer 3 from liquid storage tank 1 through pipeline 11; Deuterium gas is received bottle 2 through the variable proportioning gas mixer 3 of pipeline 21 feedings by the deuterium air-capacitor, directly carries out the deuterium nitrogen by adjusting control valve and flowmeter and is mixed, and arrives the pressure of setting, and stops inflation;
The deuterium nitrogen mixture gas that is mixed is entered surge tank 4 by pipeline 31, after deuterium gas and nitrogen are mixed certain hour, thereby utilize deuterium gas concentration analyzer 6 to detect gas concentrations and adjust deuterium gas and nitrogen amount is finely tuned mist by the accurate adjusting knob in the blender 3.
When the deuterium nitrogen mixed gas in the surge tank 4 need use, mist is filled into optical fiber processing jar 5 by pipeline 52.Keep optical fiber processing jar 5 environmental sealings, after keeping official hour under certain pressure, optical fiber processing finishes.Then, purge nitrogen to process tank 5, the deuterium/nitrogen mixed gas behind the processing optical fiber is recycled to surge tank 4 through pipeline 53 by pipeline 51.After the deuterium/nitrogen mixed gas that reclaims enters surge tank 4, thereby in processing range, will not charge into fresh deuterium/nitrogen mixed gas deuterium content is adjusted to suitable processing range by blender 3 if deuterium gas concentration analyzer 6 detects deuterium gas concentration, after treating that optical fiber processing jar 5 vacuumizes, gas in the surge tank after being mixed once more can be blown into utilization in the optical fiber processing jar 5, thereby realize the purpose of cycling and reutilization.
Because comprise hydrocarbon and other impurity in the deuterium/nitrogen that reclaims, thus the deuterium/nitrogen mixed gas that reclaims recycling can be discharged into after repeatedly outdoor.In the present embodiment, the purifier 8 that links to each other with surge tank 5, the deuterium/nitrogen mixed gas after repeatedly reclaiming is removed all gas beyond the deuterium gas by purifier 8, makes deuterium gas be collected, and has further reduced the optical fiber manufacturing cost.
