Object reduces dissolved oxygen content under the premise of not reducing polymer solution viscosity, to reach the experiment condition of evaluation.This is practical new
Type by rationally designing deaerating plant and process, it is without mixing, under room temperature deoxygenation, oxygen removal efficiency are carried out to polymer solution
It is high, at low cost, it is not related to chemical deoxidization, on polymer solution viscosity without influence, non-degradable polymer, deoxygenation is thorough, oxygen content
It can be minimum to can control within 5ppb down within 20ppb.
Summary of the invention
The purpose of this utility model overcomes the shortcomings of the prior art, and provides that a kind of oxygen removal efficiency is high, low energy consumption, in nothing
Stirring can carry out under room temperature, and the deoxygenation of polymer solution of the oxygen removal process on Properties of Copolymer Solution without influence
Device.
The purpose of this utility model can be achieved through the following technical solutions:
The deaerating plant of the polymer solution include gas source steel cylinder, surge flask, globe valve, gas flowmeter, grass tube,

That is the first nozzle and the second nozzle；
First nozzle connects one end of grass tube by silicone tube；The other end of the grass tube is inserted into
In reagent bottle, second nozzle connects gas distributor by silicone tube.
The purpose of this utility model can also be achieved through the following technical solutions:
The bottleneck of the reagent bottle is sealed with plastic packaging film, and gas vent is only stayed at grass tube；
The globe valve and gas flowmeter is sequentially arranged on the silicone tube before grass tube；
Each valve lower interface of the gas distributor is inserted into thin mouth glass by sebific duct connecting puncture needle head, piercing needle
In bottle；
For each valve lower interface of the gas distributor by sebific duct connecting puncture needle head, junction epoxide-resin glue is close
Envelope.
Compared with prior art, the utility model has the advantage that
The utility model can be used for the deoxygenation of viscosity 300cp polymer solution below.Entire oxygen removal process is in room temperature
Lower progress, it is whole without mixing, the device of the meeting degradation polymer such as metal, the expensive devices such as no glove box are not contacted, and no chemistry removes
Oxygen medicament, low cost, it is convenient to operate, on Properties of Copolymer Solution without influence, non-degradable polymer, oxygen removal efficiency height (99.9%
More than), deoxygenation is thorough, the oxygen content in the polymer solution of 3-8ppm can be reduced to 0-20ppb.
