The mode adopted by the current plant tobacco generating device mainly comes from GJB6114-2007 evaluation method for preventing plant tobacco interference of chemical reconnaissance device materials, and the generating mode is a static generating mode. The working mode is that the ignited grass sample is directly placed in a generating cabinet for a fuming test. When the smoke concentration is too low, the grass samples are combusted to increase the smoke inlet amount, and when the smoke concentration is too high, the smoke exhaust amount is increased to dilute the smoke concentration in the box body. The balance of the grass sample is adjusted by constantly igniting the sample to smoke and exhausting excess smoke to produce smoke of the desired concentration. And when the smoke concentration meets the requirement, the smoke inlet and the smoke outlet are closed simultaneously, and the static balance of the smoke concentration is maintained.
The generating cabinet has a single-layer volume of not less than 1m 3 The inner core be cavity room stainless steel cabinet, the not enough of prior art is mainly:
(1) the generation process of the vegetation smoke needs to continuously adjust the generation amount and the discharge amount of the smoke, and static balance of smoke concentration is realized by adjusting the balance of the generation amount and the discharge amount. The process of adjusting balance needs to continuously adjust and test, so that the operation process of achieving static balance is complicated, and the control difficulty is high;
(2) after the vegetation smoke reaches static balance, the vegetation smoke cannot be kept stable for a long time under the action of natural sedimentation because no smoke quantity is continuously input, and the smoke concentration is gradually reduced after being kept stable for a short time, so that the test cannot be continuously carried out for a long time;
(3) the generating cabinet is large in size and cannot be placed in a fume hood, and smoke is exhausted in a smoke extraction mode of a top end fan. The process of being fuming is because of the artificial continuous adjustment that needs, will inevitably lead to the revealing of a certain amount of smog, because of containing multiple harmful gas composition in the vegetation smog, and ordinary protection is not enough to shield all compositions of smog completely, and smog is inhaled the back by experiment operating personnel, will cause the harm to personnel's health.
