Embodiment 1

[0034] Preferably, the first pipeline 5 is provided with a first control valve 9 .

[0035] Preferably, the second pipeline 6 is provided with a second control valve 10 .

[0036] Based on above-mentioned structural system, specific embodiment of the present invention is as follows:

According to the above technical scheme, after the construction of the above-mentioned single warehouse in the cavern, the daily regulation and maintenance of the tobacco leaves stored in the cavern are carried out. When pests appear in the stacks of tobacco leaves in the cavern, this embodiment uses the following method Prevention and treatment:

At this time, the cavern 1 needs to carry out continuous gas circulation deoxidation treatment of the environment in the cavern 1. The mechanical deoxygenation and nitrogen-enriching equipment 2 blows continuous deoxygenated air into the cavern 1 to continuously reduce the oxygen concentration of the environment in the cavern. The oxygen concentration ...

specific Embodiment

[0041] Preferably, the distance between two adjacent air outlets 7 is not less than 1 meter, and the distance between two adjacent air inlets 8 is not less than 1 meter.

[0042] Preferably, the air blowing pipeline 3 extends from the middle position of the inner top of the cavern 1 to the right side, and the exhaust pipeline 4 extends from the left side of the inner bottom of the cavern 1 to the middle position.

[0043] Preferably, the first pipeline 5 is provided with a first control valve 9 .

[0044] Preferably, the second pipeline 6 is provided with a second control valve 10 .

Embodiment 2

[0046] In this embodiment, the ambient air in the warehouse is circulated and deoxygenated, and the oxygen concentration in the warehouse is reduced to prevent and control insects. Turn on the nitrogen generator, input continuously deoxygenated air into cavern 1, and open the valve on the exhaust pipe at the same time. At this time, the stale air in cavern 1 is gradually replaced through the opened pipe until the tobacco leaf pests in cavern 1 Close the mechanical deoxygenation and nitrogen-enriching equipment 2 after suffocation and death in an oxygen-deficient environment, and then close the valves of the blast pipeline 3 and the exhaust pipeline 4.

[0047] Example 3

The cavern storage tobacco leaf mechanical controlled atmosphere insecticidal system used in this embodiment is as follows: as image 3 As shown, it includes a cavern 1 for sealing and storing tobacco leaves, and also includes a mechanical deoxygenation and nitrogen-enriching device 2 arranged outside the cav...

Abstract

The invention discloses a mechanical controlled atmosphere insecticidal system for storing tobacco leaves in a cave depot and a construction and use method of the mechanical controlled atmosphere insecticidal system, the system adopts the cave depot to replace a tent sealing system, not only can a good storage system be provided for the tobacco leaves, but also the tobacco leaves can be stored in the cave depot through the operations of pumping air and filling high-purity nitrogen (the concentration of the nitrogen is generally more than 99.5%). The purpose of effectively controlling insect conditions is achieved. Tobacco leaves are basically completely placed in a storage environment of a cave depot due to practical characteristics, the effective utilization rate of the storage environment is high, and meanwhile, in view of a gas replacement and nitrogen charging mode, the warehouse is inconvenient to carry out nitrogen charging and insect killing work in the gas replacement mode. Therefore, under the condition that the unique pest control environment situation that the cave depot is good in sealing performance and high in storage environment utilization rate is fully considered, cyclic nitrogen-enriched deoxidation and pest killing work is innovatively carried out through mechanical deoxidation and nitrogen enrichment equipment.

Description

technical field [0001] The invention relates to the technical field of controlling and killing insects by tobacco leaves, in particular to a mechanical controlled atmosphere insecticide system for storing tobacco leaves in a cavern and a construction and use method thereof. Background technique [0002] Cave warehouses (generally including mountain cave warehouses and soil-covered warehouses), using cave warehouses as a storage environment with good airtightness and generally stable ambient temperature maintained between 14°C and 18°C, and relative humidity of the environment is basically 65%, which can provide good conditions for the aging of tobacco leaves. storage environment. [0003] However, the stored tobacco leaves in caverns are vulnerable to the harm of tobacco storage pests mainly tobacco beetle and tobacco meal borer. In the prior art, the pest control mainly adopts the aluminum phosphide fumigation mode to fumigate the stored tobacco leaves. In recent years, w...
