Embodiment 1

[0063] Seal the storage of grain, medicinal materials, tobacco and other agricultural products warehouses or various spaces and cabins that may breed harmful organisms to form a closed warehouse A1. In practice, the following methods are adopted for sealing:

[0064] Stacking tent: first lay a layer of plastic low film on the bottom of the stack, stack various agricultural products on the bottom film, then cover the stack with plastic tents and seal it strictly after docking with the bottom film to form a stacking tent. Six-side sealed airtight warehouse; suitable for sealing food, tobacco, and Chinese medicinal materials with outer packaging.

[0065] Whole warehouse sealing: use plastic film combined with sealant grooves or caulking glue on the doors and windows, floors, wall gaps, and pipeline wall holes of the warehouse to seal the ground plane, walls, and ceilings of the entire warehouse, or on the surface of bulk agricultural products After the plastic film is covered, t...

Embodiment 2

[0086] It is basically the same as Example 1, except that the nitrogen-enriched gas source B1 configured in the system air pressure equalization device B uses a high-pressure membrane nitrogen generator, the target gas produced by the equipment is nitrogen-enriched gas, and the oxygen produced is discharged as equipment tail gas Go to the external environment; you can use the membrane separation oxygen production equipment produced by Shanghai Ruiqi Gas Technology Co., Ltd.

Embodiment 3

[0088] It is basically the same as Embodiments 1 and 2, except that: the nitrogen-enriched gas source B1 configured in the system air pressure equalization device B uses compressed just bottled nitrogen or a nitrogen station.

Abstract

The invention belongs to the technical field of agricultural product storage and closed space harmful organism mechanical deoxidation nitrogen-rich gas conditioning prevention and control, and discloses a method for quickly and mechanically deoxidizing and enriching nitrogen in a closed bin. A system air pressure balancing device is connected into a closed circulating deoxidation and nitrogen charging system formed by mutual butt joint and communication of a closed bin, an exhaust pipeline of the closed bin, deoxidation and nitrogen enrichment equipment and an input gas pipeline of the closedbin, and comprises a nitrogen-enriched gas source, a nitrogen-enriched gas source control valve and a nitrogen-enriched gas source output pipeline; the system air pressure balancing device is connected into the circulating deoxidation and nitrogen charging system through a nitrogen-rich gas source output pipeline, the system air pressure balancing device and the circulating deoxidation and nitrogen charging system jointly construct a rapid mechanical deoxidation and nitrogen-rich system, and deoxidation and nitrogen-rich equipment in the circulating deoxidation and nitrogen charging system isstarted to extract air from the closed bin. And the separated and enriched high-concentration nitrogen is fed into the closed bin. The method has the characteristics of improving the operation efficiency of the deoxidation nitrogen-rich gas conditioning equipment and reducing the energy consumption.

Description

technical field [0001] The invention belongs to the technical field of agricultural product storage and closed space mechanical deoxygenation and nitrogen-enrichment controlled atmosphere control, and in particular relates to a method for fast mechanical deoxygenation and nitrogen-enrichment in a closed warehouse. Background technique [0002] Agricultural products are extremely vulnerable to infestation and hazards of harmful organisms in the process of storage and processing; high-speed railways, ships, and airplanes carry frequent flow of people every day, and they are also vulnerable to infestation and reproduction of harmful organisms in the process of logistics. Due to food safety and environmental safety considerations and control requirements, the safe and environmentally friendly mechanical deoxygenation and nitrogen-enriched controlled atmosphere pest control technology has become the first choice for pest control in agricultural product storage warehouses and confi...
