Description
Technical field
The present invention relates in a kind of Exclusion analysis device the gas and liquid of impact analysis result method.
Background technology
In the Water Test Kits being such as measured to the COD (COD) of sewage using AAS, sewage with
Reagent is mixed in reaction tank, and the inwall in reaction tank after the sample to mixing is heated can condense and have liquid, together
When, if the mercuric sulfate as screening agent described in being added without GB GB11914-89, only using addition sulfuric acid and ventilation
The method of heating to remove the chlorion in sewage, can be discharged in the form of hydrogen chloride gas by chlorion, and the chlorine discharged
Change hydrogen can be dissolved in the liquid of condensation again and and reagent reacting generation sediment, so as to affect the precision of measure, thus
Before being measured to sample, it usually needs discharge to improve measurement accuracy by the liquid that the gas in reaction tank and inwall condense.
To reaction tank into injection air method to take away gas and liquid is adopted in prior art generally.As shown in Fig. 2 anti-
Answer pond 6 to seal by briquetting 2, the flexible pipe 1 of air inlet and outlet is respectively arranged at the two ends of reaction tank, the one of air inlet
End is also associated with for injecting the air pump 7 of air 5, when needing to discharge the liquid 3 of gas 4 and condensation in reaction tank,
Open air pump and air is injected into reaction tank, on the one hand the air of injection can play a part of to mix sample, the opposing party
Gas 4 in reaction tank can be discharged by face by the air-out hose of upper end, while can also carry out the liquid of condensation.But it is existing
With the presence of the following problem of method：
1st, it is not easy the gas for needing to discharge all to emit when air is injected；
2nd, it is not easy the liquid condensed at the top of reaction tank all to emit when air is injected；
If the dynamics for the 3, injecting air is too big easily so that sample sputters in reaction tank.
The content of the invention
According to the present invention, there is provided a kind of method for discharging the gas and liquid of impact analysis in analytical equipment, described point
Analysis apparatus include reaction tank, and the sample that the reaction tank is mixed built with the plurality of reagents as analysis object is described anti-
Ying Chi is sealed and is respectively arranged with air inlet and gas outlet at the two ends of the reaction tank, and the gas outlet is connected with
High pressure valve, the method comprising the steps of:Close the high pressure valve；Injected into the reaction tank by the air inlet
Air；The high pressure valve is opened after the pressure in the reaction tank reaches predetermined value.
It is according to another embodiment of the present invention square described in the method for the gas and liquid of impact analysis in analytical equipment for discharging
Method is comprised the following steps:Close the high pressure valve；The plurality of reagents is injected by several times into the reaction tank；When the reaction
Pressure in pond opens the high pressure valve after reaching predetermined value.
According to further embodiment of this invention for the method for discharging the gas and liquid of impact analysis in analytical equipment, the side
Method is comprised the following steps:Close the high pressure valve；The reaction tank is heated so that the temperature in the reaction tank surpasses
Cross the boiling point of the sample；The high pressure valve is opened after the pressure in the reaction tank reaches predetermined value.
Invention effect
Method according to the invention it is possible to greatest extent by the liquid of condensation while the gas for needing to discharge is emitted
Body is also together taken out of, and is prevented from sample splashing.

Specific embodiment
Referring to the drawings the method according to the invention is illustrated.
Fig. 1 is the schematic diagram of method according to an embodiment of the invention.As shown in figure 1, on the basis of existing technology,
The method of the present invention increased the high pressure valve of gas outlet one end.When needing to discharge in reaction tank unwanted gas and during liquid,
Firstly the need of high pressure valve is closed, then air is injected into reaction tank so that the air pressure in closed reaction tank is raised, when
After reaching certain pressure, high pressure valve release gas is opened.Due to the effect of high pressure, need in reaction tank the gas discharged and
The liquid of condensation together can be taken out of, and also while can be discharged if having residual liquid in the flexible pipe of outlet side.
Unwanted gas and liquid can be discharged from reaction tank by the method according to the invention to greatest extent, and
During injection air, high pressure valve is closed, and is also not in as the dynamics for injecting air is easily made greatly very much in prior art
In obtaining reaction tank, sample sputters the problem come.
Method as above causes the air pressure in reaction tank to raise by injecting air, but the present invention is not limited to this.Under
Face will describe method in accordance with another embodiment of the present invention.
Due to the volume of reaction tank be it is certain, therefore can be reached by way of compressed gas volume rising reaction tank in
The purpose of air pressure.High pressure valve still first will be closed by method according to another embodiment of the invention first, then will measurement
It is injected in reaction tank with reagent by several times, the gas volume in original reaction tank is certain, after injection reagent, gas
Volume is compressed, and so as to the air pressure in reaction tank is raised, after certain pressure is reached, opens high pressure valve release gas.Together
Sample, using such method, needs the gas discharged and the liquid of condensation be discharged in reaction tank.
According to the method for further embodiment of this invention, it is not necessary to the effect for discharging gas and liquid can also be reached by injecting air
Really.Concrete grammar is as follows, is first shut off high pressure valve, then reaction tank is heated so that the temperature of reaction tank is higher than examination
The boiling temperature of sample, as reaction vessel is sealing, therefore the rising of temperature can cause the air pressure rising in reaction tank, when
After reaching certain pressure, high pressure valve release gas is opened.Due to the effect of high pressure, gas and the knot discharged in reaction tank, is needed
The liquid of dew can be discharged.In the case of in this way, the flexible pipe and air pump of air inlet as shown in Figure 1 are not must
Must.
By the method for the present invention so that the pressure rise in reaction tank, beat after the pressure rise in reaction tank is to predetermined value
High pressure valve is opened, can be to greatest extent while the gas for needing to discharge is emitted by the liquid of condensation using high pressure
Together take out of, and be prevented from sample splashing.
More than, by concrete by taking the Water Test Kits that AAS is measured to the COD (COD) of sewage as an example
The method according to the invention is described, but, the use of the method for the present invention is not limited in Water Test Kits, this area skill
Art personnel are appreciated that in the device or equipment that all multipair samples are analyzed, there are exclusion and tie to measuring or analyzing
The requirement of really influential gas and liquid, therefore, the method for the present invention is generally applicable in these analytical equipments or equipment.
Although the present invention is disclosed above with preferred embodiment, it is not for limiting the present invention, any art
Technical staff, without departing from the spirit and scope of the present invention, fraction of change and retouching, therefore the present invention can be made
Protection domain is by being defined that claim is defined.
