Abstract

The utility model discloses a device for measuring oxygen content in chlorine, comprising a single stopcock sampling pipe. The bottom part of the single stopcock sampling pipe is communicated with a leveling bottle through a soft pipe, the bottom part of the single stopcock sampling is provided with a cock, and the top part of the single stopcock sampling pipe is provided with a latex pipe on which a water stopping clamp is arranged. A certain amount of chlorine is taken through the single stopcock sampling pipe and then absorbed by lye in the leveling bottle, and the oxygen content is measured by injecting the remaining gas in the single stopcock into gas phase chromatography; and the device has high accuracy in oxygen content measuring, and is conveniently used.

Description

The determinator of oxygen level in chlorine
Technical field
The utility model relates to oxygen containing determinator in a kind of chlorine.
Background technology
In chlorine industry, in chlorine, oxygen level exceeds standard many adverse effects.As, in chlorine, oxygen level exceeds standard has increased energy consumption, reduces current efficiency; Simultaneously, reduced the purity of product, in liquefaction process, because the existence of oxygen can reduce the chlorine gas liquefaction temperature; In addition, in chlorine, oxygen level exceeds standard and will produce harm to ion-exchange membrane electrolyzer anode active coating, will shorten the serviceable life of anode coating.This makes to control and contains oxygen in chlorine and seem particularly important.Domestic chlor-alkali industry generally adopts the bulbs,double absorption process to oxygen containing analysis in chlorine, adopts the scale stopple coupon to measure oxygen level, uses more directly perceived.But the stopple coupon minimum scale is 0.2, after radix point is to estimate the numerical value of reading, and accuracy is relatively relatively poor.In addition, adopt absorption process to make sample, add the process of water air-discharging, two devices will tilt simultaneously, and this operating process needs two people's cooperations to complete, and operation is comparatively complicated, easily causes the increase of error.In practical operation, occasionally have accidentally, the phenomenon of the pyrogallic acid potassium ejection in the bulbs,double device also can appear, and the clothing of making dirty, scene etc. are unfavorable for personnel's operation very much.
Summary of the invention
The purpose of this utility model is to overcome the determinator that above-mentioned deficiency provides oxygen level in a kind of chlorine.
For achieving the above object, the utility model is by the following technical solutions:
The determinator of oxygen level in a kind of chlorine, comprise single plug stopple coupon, the bottom of single plug stopple coupon 4 is communicated with leveling bottle by flexible pipe, is provided with cock in the bottom of single plug stopple coupon, the napex of single plug stopple coupon is provided with emulsion tube, is provided with tongs on emulsion tube.
The determinator of oxygen level in above-mentioned chlorine, described emulsion tube top is provided with short glass tube.
Adopt technique scheme, the utility model has following advantage: measure a certain amount of chlorine by single plug stopple coupon of the present utility model, then chlorine is passed through the alkali liquor absorption in leveling bottle, the residual gas injection gas chromatography in single plug stopple coupon is measured oxygen level.The oxygen level accuracy that the utility model is measured is high, easy to use.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The determinator of oxygen level in a kind of chlorine as shown in Figure 1, comprise single plug stopple coupon 4, the bottom of single plug stopple coupon 4 is communicated with leveling bottle 6 by flexible pipe 7, bottom at single plug stopple coupon 4 is provided with cock 5, the napex of single plug stopple coupon 4 is provided with emulsion tube 3, be provided with tongs 2 on emulsion tube, emulsion tube 3 tops are provided with short glass tube 1.
The course of work of the present utility model is as follows: measure a certain amount of chlorine by single plug stopple coupon of the present utility model, then chlorine is passed through the alkali liquor absorption in leveling bottle, the residual gas injection gas chromatography in single plug stopple coupon is measured oxygen level.The utility model is to be used in conjunction with gas chromatography, measures oxygen level in chlorine.Gas chromatography adopts 5A molecular sieve chromatography post, thermal conductivity detector (TCD), and hydrogen is done carrier gas.
Concrete steps:
(1) calibration: adopt dry air as Standard Gases, use the micro syringe sample introduction, calibration.
(2) survey purity of chlorine gas feeding (reading after alkali liquor absorption) with single plug stopple coupon, the upper end adopts emulsion tube to connect, and tongs is set on emulsion tube; During operation, reverse the lower end cock, make the pipe internal and external pressure balance.
(3) squeeze the residual globule in the emulsion tube of upper end with finger, it is rushed in stopple coupon; Again leveling bottle is increased to tongs top (gas is as malleation in the bonding plug stopple coupon).
(4) with microsyringe from the upper end emulsion tube, extract residual gas, sample introduction.
(5) result is calculated:
In formula: Vs---tested component concentration (volume fraction) in Standard Gases;
Ai---the numerical value of tested component peaks area in sample gas;
As---the numerical value of tested component peaks area in Standard Gases.

Claims (2)
