Embodiment 1

[0039] Example 1: Such as Figure 1 to Figure 6 As shown in the figure, a grain storage lateral nitrogen charging system includes a grain storage storage body 1 and a membrane separation nitrogen generator 2, and also includes two air-conditioning air duct structures. The grain storage body includes two parallelly arranged long sides. Side wall 11, short side walls and roof 12 arranged in parallel on both sides, the lower end of the long side wall is connected to the ground, the lower end of the short side wall is connected to the ground, and the air-conditioning air duct structure corresponds to the long side wall one by one;

[0040] In the corresponding air channel structure and long side wall: the air channel structure includes a wall air channel 31 arranged on the long side wall, an opening and closing door 32 that can be used to close one end of the wall air channel, and another wall air channel. A main air pipe 33 connected at one end and a plurality of vertical branch air ...

Embodiment 2

[0048] Embodiment 2: The basic structure and implementation of this embodiment are the same as those of Embodiment 1, the difference lies in that Figure 7 to Figure 12 As shown in the corresponding air-conditioning air duct structure and long side wall: the air-conditioning air duct structure also includes a rear glue cylinder 36 arranged on the long side wall, and the long side wall is provided with several embedded long side walls. The first rubber storage tube 41 in the side wall, a number of second rubber storage tubes 42 embedded in the long side wall, and a number of third rubber storage tubes 43 embedded in the long side wall, the wall airway is cylindrical, and the wall airway diameter Upward, the first rubber storage tube is between the inner sealing ring and the wall air passage, the second rubber storage tube is between the inner sealing ring and the outer sealing ring, and the third rubber storage tube is between the outer sealing ring and the outer edge of the bott...

Abstract

The invention discloses a grain bin transverse nitrogen-charging adjustment system. The system comprises a grain storage bin and a membrane separation nitrogen generator, and further comprises two air-adjusted air duct structures; the air-adjusted air duct structures comprise wall air ducts, open-close doors, main air ducts and a plurality of vertical support air pipes, a plurality of air holes are formed in the vertical support air pipes, and nitrogen supplying air holes are connected to one end of the nitrogen supplying pipe in a butt joint mode; connectors which are connected with the wall air duct of one air-adjusted air duct structure in a butt joint mode are arranged at the other end of the nitrogen supplying pipe, air inlets of a nitrogen preparation main engine are connected to one end of an air return pipe in a butt joint mode, and the connectors which are connected with the wall air duct of another air-adjusted air duct structure in a butt joint mode are arranged at the other end of the air return pipe; a nitrogen supplying on-off valve is arranged on the nitrogen supplying pipe, and a nitrogen concentration detection instrument and a pressure determinator are all arranged on the air return pipe. The grain bin transverse nitrogen charge air-adjusted system has the advantages that a grain bin can be effectively filled with nitrogen, accordingly, grain piles in the grain bin can be effectively subjected to disinfestation, mould inhibition and preservation, and the system is good in gas distribution uniformity, high in nitrogen efficiency and less in nitrogen waste.

Description

Technical field [0001] The invention relates to the technical field of controlled-atmosphere grain storage, in particular to a horizontal nitrogen-filling regulation system for a grain warehouse and a controlled-atmosphere grain storage method. Background technique [0002] The controlled atmosphere grain storage technology is one of the internationally recognized green beam storage technologies. It is a green and safe beam storage technology that integrates insecticide, insect control, mildew suppression, and freshness preservation. Specifically, controlled-atmosphere grain storage refers to artificially changing the gas composition of the normal atmosphere or adjusting the original gas ratio to control the concentration of a certain gas within a certain range and maintain it for a certain period of time, so as to achieve insecticide and mildew Grain storage technology that delays changes in grain quality. At present, it is relatively common to pass nitrogen into the grain depo...
