Description
Technical Field
The utility model relates to the technical field of tobacco insect disinfestation, in particular to a tobacco storage insect disinfestation system and a tobacco storage system.
Background
In the process of storing tobacco leaves, the tobacco leaf is often damaged by tobacco storing pests, and the tobacco beetles and the tobacco stem borers are the most main tobacco storing pests. The existing insecticidal methods comprise an aluminum phosphide fumigation method for controlling tobacco storage pests and an air-conditioning insecticidal method for reducing the oxygen amount in a closed cavity for containing materials.
The aluminum phosphide fumigating process has extremely toxicity and water-encountering explosion, and the tail gas and residues of aluminum phosphide fumigating have adverse effects on the environment, so that the aluminum phosphide serving as a high-efficiency fumigating pesticide has great ecological and safety defects, namely limited use, and therefore, the development of gas-regulating disinsection becomes a new choice.
The air-regulating disinsection technology also comprises a mechanical nitrogen charging regulation technology of a nitrogen making machine and an oxygen reducing regulation technology of an air regulator.
The existing nitrogen-making machine mechanical nitrogen filling and regulating technology generally only can generate 99% of nitrogen, and after the tobacco leaves of the sealing stack are filled with the 99% of nitrogen, the oxygen of the sealing stack is finally reduced from 21% to 1% -2%, and the nitrogen is always filled with nitrogen to keep low oxygen by 2%, so that the tobacco leaf pests of the sealing stack can be killed. The oxygen in the sealing stack can be reduced from 21% to 1% -2% after nitrogen is filled for 3-4 days, but the oxygen is maintained to be low (1% -2%) for more than 20 days under the concentration, so that the insect killing is performed, and the air-conditioned insect killing time is also influenced by the environmental temperature of the tobacco stack.
The existing oxygen reduction and adjustment technology adopting the air regulator is used for preparing the insecticidal environment with the oxygen concentration lower than 2%, the air regulator is required to react with oxygen in the air in the sealed tobacco stacks, the ambient temperature is higher than 25 ℃, and the insecticidal environment preparation with the oxygen concentration lower than 2% is generally realized through 10-day absorption reaction. And after the insecticidal environment is kept below 2% for about 15 days, the insect pests in the sealed tobacco stacks are killed. By adopting the air-conditioning technology for disinsection, the oxygen absorption chemical reaction of the air-conditioning agent and the air-conditioning disinsection time are also influenced by the environmental temperature of the smoke stack.
Compared with aluminum phosphide fumigation insecticidal, the two gas-regulating insecticidal technologies adopted at present have the advantages of long insecticidal time, large environmental influence and limited practical popularization and use. The two kinds of air-conditioned insecticidal time are also influenced by the environmental temperature of the tobacco stacks.
The disadvantages of the prior art are as follows:
(1) compared with aluminum phosphide fumigation insecticidal, the two gas-regulating insecticidal technologies adopted at present have the advantages that the insecticidal time is prolonged, the tobacco leaf production arrangement is affected, and the practical popularization and use are limited.
(2) The two kinds of gas-regulating insecticidal techniques that adopt at present are influenced greatly by ambient temperature, and gas-regulating insecticidal time still receives the influence of cigarette buttress ambient temperature, and the direct extension insecticidal time of temperature reduction influences the tobacco leaf production arrangement, and simultaneously, insecticidal time extension changes, can't confirm the effective time that kills the tobacco worm, is unfavorable for judging insecticidal quality.
(3) The existing nitrogen making machine mechanical nitrogen filling adjustment technology is difficult to control the oxygen concentration below 0.5 percent due to the technical characteristics, and the insecticidal effect is greatly reduced.
(4) The existing two air-conditioning insecticidal technologies are adopted, and measures are not taken to control the air-conditioning insecticidal temperature, so that a certain air-conditioning insecticidal time cannot be provided, and the air-conditioning insecticidal quality cannot be ensured.
(5) Compared with aluminum phosphide fumigation, the two gas-regulating insecticidal technologies adopted at present have long insecticidal time, and mainly have higher oxygen insecticidal concentration (below 2%) in a control stack, so that quick insecticidal cannot be realized. Meanwhile, the existing two air-conditioning insecticidal technologies cannot quickly realize the technology for controlling the concentration (below 0.5%) of oxygen insecticidal in a stack.
