The flow dividing device comprises a triple valve and an auxiliary attractive force source; the dilution device comprises a compressed air inlet pipe and a pressure regulation device thereof, as well as a Dekati Diluter. The system is simple in the gas path connection between the cigarette smoke generating device and aerosol detection equipment; through the modes of diluting, dividing flow, setting appropriate gas flow speed, etc., the system successfully ensures that cigarette smoking meets requirements when smoke aerosol samples are collected, and the concentration of the samples entering a detector is in an effective detection range of the equipment.
Description
Technical field
The utility model belongs to technical field of analysis and detection, is specifically related to a kind of system that cigarette flue gas aerosol detects that is used for.
Background technology
In the prior art, the process that aerosoloscope is used for measuring the air aerosol particle is: by the suction source device of detecting device itself, stablizing flow velocity usually is 10L/min～40L/min, outwards the intake-gas sample; When sample concentration is higher, also can connects an axial diluter sample is diluted.
When adopting aerosoloscope to measure cigarette smoke,, cause detecting device seriously to transship because aerosol concentration is higher than airborne situation far away in the flue gas.Testing result occurs and exceed the instrument detecting upper limit (4.0 * 10
5FA), indifference between each detected value has all reached situations such as maximal value, can't carry out check and analysis.Even the diluted sample device that adopts producer to provide for the high sample of tar content, does not still satisfy requirement; To the detection of low tar amount cigarette sample, line clogging also usually appears, and pressure-drop in pipeline is increasing in the testing process, gas velocity acute variation in the cigarette smoking process, the sample situation that traps before and after causing is inconsistent.
In the detection technique of cigarette flue gas aerosol, lack a kind of adjustable gas flow velocity of simple and stable and the system of concentration, to such an extent as to can not utilize existing aerosoloscope to detect aerosol load in the cigarette smoke.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of detection system that is used for cigarette flue gas aerosol is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of system that cigarette flue gas aerosol detects that is used for is provided, comprise the cigarette smoke generating means, part flow arrangement, air mix facilities and the gasoloid detector that connect successively by gas pipeline, described part flow arrangement comprises T-valve and auxiliary suction source, and described air mix facilities comprises compressed air inlet pipe and regulator and Dekati Diluter diluter.
Described auxiliary suction source comprises suction source and regulator.
Described auxiliary suction source comprises the adjustable speed suction source.
Described auxiliary suction source task performance requires to be 1mL/min～2mL/min
Described Dekati Diluter diluter dilution ratio is 200: 1～500: 1.
Described regulator is pressure regulator valve or pressure regulator valve and flowmeter.
Flow into the sample gas of aerosoloscope, be called for short sample flow 3, gas velocity is limited by existing conventional aerosoloscope, normally a fixed value, can't regulate, its value is generally 10L/min～40L/min.
Dekati Diluter diluter dilution ratio is 200: 1～500: 1.The flow velocity of diluter air intake opening and gas outlet, i.e. dilution ratio is limited by the model of diluter.It is 200: 1～500: 1 that the utility model is selected the dilution ratio of Dekati Diluter diluter for use according to the adjusting situation of air-flow, can ensure that sample flow 3 flow velocitys meet the requirement of aerosoloscope.
The flue gas generating means can be set to smoking machine and solenoid valve.Air-flow from the flue gas generating means flows out is called sample flow 1, and the requirement that its flow velocity must meet the cigarette examination criteria is provided with, and can not arbitrarily adjust, and detects according to difference to require its value at 1mL/min～1.8mL/min.Solenoid valve can communicate with surrounding air, detects according to cigarette to require to be provided with, and 2s is communicated with the smoking machine smoking cigarette usually, and 58s switches to draws ambient air, carries out repeatedly finishing up to cigarette smoking.
Auxiliary suction source task performance requires to be 1mL/min～2mL/min, pressure regulator valve or pressure regulator valve and flowmeter are set simultaneously to be regulated, the gas velocity that ensures sample flow 1 meets 1mL/min～1.8mL/min area requirement, and sample flow 2 is 1/8～1/3 of sample flow 1 gas velocity.By air mix facilities, aerosol sample concentration is carried out 200: 1～500: 1 dilution, acquisition meets the flue gas stream of the requirement of aerosoloscope.
The beneficial effects of the utility model are: the utility model flue gas generating means is connected simply with gas circuit between the gasoloid checkout equipment, the task performance of suction source requires lower, but set modes such as appropriate gas flow speed by dilution and shunting, cigarette burnt and sucked and meets the requirements when the flue gas aerosol sample guarantee was gathered in success, and entered sample concentration in the detecting device in the valid analysing range of equipment.
The utility model has been realized the detection to cigarette flue gas aerosol, does not need to detect the special-purpose gasoloid checkout equipment of exploitation for cigarette smoke.Detect effect and obviously improve, realize the flue gas aerosol situation is analyzed more accurately.
