Background technology
Existing gasoloid detecting instrument is commonly used to measure the quality situation of the size-grade distribution in the gasoloid and each granularity in the air.
The test sample entraining air stream amount of cigarette industry iso standard defined requires 17.5 ± 0.15mL/s.If adopt this sample gas directly to utilize existing gasoloid detector gas to carry out the detection of flue gas aerosol size-grade distribution situation, do not satisfy of the requirement of gasoloid detecting instrument to sample flow; Aerosol concentration is higher than airborne situation far away in the flue gas, will cause detecting device seriously to transship, and can't carry out check and analysis.
The applicant finds to utilize existing gasoloid detecting instrument to detect gasoloid in the flue gas through to a large amount of experimental studies of cigarette both at home and abroad, and requiring flue gas flow usually is less than 1.75mL/s or littler.In other words, flue gas flow is during less than 1.75mL/s, and existing gasoloid detecting instrument can be measured the flue gas aerosol result more accurately.According to this point, the applicant wishes to design a cover system, can obtain the sample gas that can satisfy tobacco business iso standard defined requires also can increase suction capacity, the sample gas that can utilize existing gasoloid detector to detect again for the needs of experimental study.
The utility model content
The purpose of this utility model is to fill up the blank of prior art, provides a kind of cigarette flue gas aerosol to detect the preparation system of using sample gas.
The technical solution of the utility model is:
A kind of preparation system of cigarette flue gas aerosol test sample gas is provided, comprise smoking machine, solenoid valve, metering hole, T-valve and waste discharge device, smoking machine is connected with metering hole with solenoid valve successively by gas pipeline, metering hole is connected by gas pipeline with T-valve, outlet of T-valve is connected with the waste discharge device with flowmeter successively by gas pipeline, and another outlet is connected with solenoid valve, flowmeter and gasoloid detecting instrument successively by gas pipeline.Described valve opening solenoid 2s closes 58s.
Described waste discharge device comprises compressed air inlet pipe road, solenoid valve, pressure regulator valve and negative pressure generator, and negative pressure generator is provided with gas outlet, and described valve opening solenoid 5s closes 55s.
Smoking machine is connected with solenoid valve, the process of simulation suction cigarette, and solenoid valve detects according to cigarette and requires to be provided with, and is generally out 2s, closes 58s, carries out repeatedly finishing up to cigarette smoking.The flue gas solenoid valve of flowing through flows out, and flows into metering hole.
According to prior art, by the setting of metering hole, the cigarette smoke gas velocity that is flowed out by smoking machine is adjusted to 17.5mL/s～25mL/s.The flue gas sample is by the gas pipeline T-valve of flowing through, and through the T-valve shunting, part of smoke is sucked by the negative pressure generator of waste discharge device through flowmeter, and another part enters the gasoloid detecting instrument through solenoid valve and flowmeter successively.
Pressurized air enters negative pressure generator from draft tube through solenoid valve and pressure regulator valve, and valve opening solenoid 5s closes 55s, and effect is to make sample gas can enter analytical instrument fully.Regulate compressed-air actuated flow by pressure regulator valve, thereby regulate the flue gas flow that enters in the negative pressure generator.The flue gas flow that enters negative pressure generator usually be set be 10～20 times that enter gasoloid detecting instrument flue gas flow.The flue gas flow that enters negative pressure generator by adjusting realizes entering gasoloid detecting instrument flue gas flow less than 1.75mL/s.Flowmeter helps more intuitive Control Flow.
The beneficial effects of the utility model are:
The utility model provides a kind of sample gas requirement that can satisfy tobacco business iso standard defined, can utilize the preparation system of the sample gas that existing gasoloid detector detects again, for tobacco manufacturing enterprise effectively detect and the control flue gas in aerosol load technical foundation is provided.
Simultaneously, the utility model simple structure, easy to use, low cost of manufacture has very high promotional value and standardization prospect.
