Abstract

The invention discloses a transverse circulation type granary insect killing system, which comprises a granary, a first air return pipe, a first air inlet pipe, a second air return pipe and an annularflow fan, wherein the air return pipe and the second air return pipe are communicated through an air return pipeline; an air inlet pipeline is arranged on the first air inlet pipe; the first air return pipe, the circulation fan, the air inlet pipeline and the first air inlet pipe are sequentially communicated; a first on-off valve, a discharging pipe and a nitrogen preparation and conveying pipeare arranged on the air inlet pipeline; the nitrogen preparation and conveying pipe is in butt joint with an air outlet of the nitrogen preparation machine; a discharging on-off valve is arranged on the discharging pipe; a nitrogen conveying on-off valve is arranged on the nitrogen preparation and conveying pipe; the air inlet end of the discharging pipe communicates with the air inlet pipeline; the air outlet end of the nitrogen conveying pipe communicates with the air inlet pipeline. The transverse circulation type granary insect killing system has the beneficial effects that the structure is reasonable; the nitrogen inflation can be effectively performed on the inside of the granary, so that the sterilization and insect killing can be facilitated; the mildew inhibition and fresh keepingof the grain stack can be realized; the nitrogen inflation uniformity is high; the nitrogen inflation effect is good; the nitrogen gas waste is little; after the nitrogen inflation, the whole nitrogen gas distribution uniformity is good.

Description

technical field [0001] The invention belongs to the technical field of grain storage, and in particular relates to a horizontal circulation type granary insecticidal system. Background technique [0002] Controlled atmosphere grain storage technology is one of the internationally recognized green storage beam technologies. It is a green and safe storage beam technology that integrates insecticide, insect control, mildew suppression, and freshness preservation. Specifically, controlled atmosphere storage refers to artificially changing the gas composition of the normal atmosphere or adjusting the ratio of the original gas, so as to control a certain gas concentration within a certain range and maintain it for a certain time, so as to achieve insecticidal and mildew suppression. Grain storage technology that delays changes in grain quality. However, the current controlled atmosphere grain storage technology using nitrogen is deficient in terms of gas supply effect, nitrogen u...
