Description
Technical field
The detection of combustion product gases is the utility model is related to, is specifically oxygen consumption amount detecting device during a kind of cigarette is burnt and sucked.
Background technology
In aspiration procedure, a series of physical and chemical reaction occurs cigarette for pipe tobacco, forms substantial amounts of product, there is 5000
It is a variety of.Wherein harmful components have 149 kinds, including tar, and CO, nitrosamine, aldehyde and nitro hydrocarbon etc., they there is harm to make human body
With.Smoking is harmful to your health, although the theory of tobacco control is constantly being promoted, but still has many people smoking.In order to reduce cigarette smoking
During harmful substance yield, study during cigarette smoking influence harmful substance produce factor become to close weight
Will.The harmful substance major part that cigarette smoking produces by the macromolecular compound imperfect combustion in tobacco and is cracked to form, cigarette
Careless unique nitrosamine is by being that tobacco physical action produces, and such reaction and the heat that is produced in aspiration procedure are closely related, again
Due to the oxygen positive correlation consumed in reaction quantity of heat production and aspiration procedure.And oxygen consumption is more, quantity of heat production is bigger, reaction

Obtain the concentration of under test gas.Detection cigarette is unignited respectively and lights the concentration of under test gas after suction, and two concentration are subtracted each other
Can obtain the oxygen demand that cigarette burns and sucks a bite, carry out continuous sucking, you can obtain that cigarette burns and sucks by mouth oxygen demand.
Comprise the following steps that：
1. triple valve a, triple valve b, two-way valve a, two-way valve b, triple valve c at the same time it is electric interconnect, nitrogen cylinder afterwards
In nitrogen 10s cleanings are carried out to whole conducting pipeline, make to be full of nitrogen in pipeline；
2. triple valve a cuts out system pipeline, it is set to connect air；Two-way valve a is closed；Two-way valve b is stayed open；
3. triple valve c switching states make it connect vacuum pump after 1s, vacuum pumping 9s, is pumped into gas absorption cell
Vacuum state；
4. two-way valve b is closed；Triple valve c cuts out system pipeline after 1s, it is connected air, and triple valve b connections suction is single
First pump unit aspirates 2s, completes the suction of 35ml；
5. switching three-way valve b, makes it connect triple valve a, the 35mL flue gases of suction enter subsequent pipeline, are saved in three
Between port valve a and pump unit.Two-way valve a is opened after 3s, and the under test gas in pipeline is inhaled into the integrated form being evacuated

The foundation of the detection method is dexterously to be pressed by the rule that oxygen content under the conditions of constant temperature and pressure constant humidity is constant
Aspirated according to international standard suction mode, detect first cigarette it is unignited before suction a bite when oxygen concentration, then detect volume
The remaining concentration of oxygen after every mouth when cigarette is burnt and sucked, the difference of two concentration are the oxygen demand during every mouthful of cigarette is burnt and sucked.
More specifically, the photodetector system is provided the saw of low frequency by laser controller and temperature controller respectively
The sinewave modulation signal of tooth ripple modulated signal and high frequency, laser are modulated.Modulated laser beam is through integrated gases
In absorption cell gas absorb and opto-electronic conversion after, through two frequency multiplication of data collector demodulation after be sent into computer upper computer software into
Row processing, obtains the absorbed second harmonic strength signal of under test gas.The peak signal of second harmonic is demarcated through calibrating gas
Afterwards, the concentration of under test gas is obtained.
The specification of pipeline in the flue gas suction trapping system between triple valve a and triple valve b needs to meet certain
Requirement, the volume of pipeline is 50-500mL.Because cigarette is after the pump unit suction driven by servomotor, flue gas quilt
Discharge into gas pipeline.Since flue gas cannot need to be full of nitrogen, be made the flue gas of suction in nitrogen atmosphere by air pollution, pipeline
In.Flue gas cannot introduce foreign gas during being sucked into the integrated gases absorption cell of vacuum pumping at the same time.To sum up, pipeline
The volume of middle nitrogen should be more than the volume and cigarette holder to integrated gases absorption cell front end of integrated gases absorption cell
Between the sum of conduit volume.
