Abstract
The utility model discloses a system for preparing detecting sample gas of cigarette smoke gas aerosol, comprising a cigarette smoke gas generator, a three-way valve and a waste discharge device, wherein, the cigarette smoke gas generator comprises a negative pressure generator and a solenoid valve which is connected with the three-way valve through a gas pipe; and one outlet of the three-way valve is connected with the waste discharge device through a gas pipe and the other outlet of the three-way valve is connected with the solenoid valve and an aerosol detecting instrument in turn through a gas pipe. The system adopts proper gas path design and realizes monitoring of the particle size distribution condition of the aerosol in cigarette smoke gas by utilization of the prior aerosol detecting instrument.
Description
Technical field
The utility model belongs to the detection technique field, is specifically related to a kind of cigarette flue gas aerosol and detects the preparation system of using sample gas.
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.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, this China invites the person wishes to design a cover system, the sample gas that can utilize existing gasoloid detector to detect.
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 cigarette smoke generating means, T-valve and waste discharge device, described cigarette smoke generating means comprises smoking machine and solenoid valve, solenoid valve is connected with T-valve by gas pipeline, outlet of T-valve is connected with the waste discharge device by gas pipeline, and another outlet is connected with the gasoloid detecting instrument with solenoid valve successively by gas pipeline.
Described waste discharge device comprises metering hole, negative pressure generator or vacuum peristaltic pump, compressed air inlet pipe road and solenoid valve, and described valve opening solenoid 5s closes 55s.
Described cigarette smoke generating means comprises smoking machine and solenoid valve, the cigarette of burning is by the process of negative pressure generator and solenoid valve simulation suction cigarette, 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.Flue gas flows out through solenoid valve, flows into T-valve.Smoking machine also can adopt cigarette to prop up clamper and substitute.
The beneficial effects of the utility model are:
The utility model provides a kind of preparation system that can utilize the sample gas that existing gasoloid detector detects, 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.

Embodiment
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Embodiment 1
Structure as shown in Figure 1, a kind of preparation system of cigarette flue gas aerosol test sample gas comprises cigarette smoke generating means, T-valve and waste discharge device.
The cigarette smoke generating means comprises smoking machine and solenoid valve 1, the cigarette of burning is by the process of smoking machine and solenoid valve 1 simulation suction cigarette, solenoid valve 1 detects according to cigarette and requires to be provided with, and is generally out 2s (being communicated with 2s with smoking machine), closes 58s, carries out repeatedly finishing up to cigarette smoking.Flue gas flows out through solenoid valve 1, flows into T-valve.
Outlet of T-valve is connected with the waste discharge device by gas pipeline, the waste discharge device comprises with individual metering hole, negative pressure generator or vacuum peristaltic pump, compressed air inlet pipe road and solenoid valve 3, the flue gas that the flows out T-valve metering hole of at first flowing through, flow into negative pressure generator or vacuum peristaltic pump then, pressurized air flows into negative pressure generator by a solenoid valve 3, open 5s by solenoid valve 3, close the setting of 55s, adjusting enters the compressed air require of negative pressure generator, thereby regulate the flow (flow velocity) of the flue gas F2 that enters negative pressure generator, final flow rate regulation to the 1～1.75mL/s that is flowed into the flue gas stream F1 of aerosoloscope by solenoid valve 2 that regulates, negative pressure generator is provided with gas outlet.
By the utility model system, can successfully prepare and to utilize existing aerosoloscope to carry out the cigarette sample air-flow that flue gas aerosol size-grade distribution situation detects.
