Circulation fumigation in Zhengzhou Zhonggu

☆ NakataniCirculation fumigation, circulation fumigation--Working principle:
The circulation fumigation system is divided into fixed and mobile types according to the fixed method of the circulation pipeline. Fixed type refers to the pipeline being fixed to the warehouse wall (fixed to the outer wall of the warehouse for external circulation, fixed to the inner wall of the warehouse for internal circulation), mobile type refers to the air intake pipeline and air volume control valve being fixed to the warehouse wall, and the fan and air outlet air volume balance adjustment device being installed on the mobile trolley (mobile circulation machine). The air intake pipeline is connected to the circulation machine through a flexible hose. Zhengzhou ZhongguCirculation fumigation--Related knowledge:
The circulation fumigation system can be divided into whole warehouse circulation fumigation and subsurface circulation fumigation according to whether there are pipelines under the grain surface.? The whole warehouse circulation fumigation does not cover the grain surface with plastic film, and the fumigation gas circulates throughout the entire warehouse composed of the space above the grain surface and the grain pile. This method is used for warehouses with good air tightness. Under membrane circulation fumigation is a method of laying pipelines under the grain surface, covering the grain surface with plastic film, and circulating fumigation gas in the grain pile below the grain surface. It is suitable for various airtight conditions in warehouses.
For new and old warehouses that do not meet the required airtightness, circulation pipes can be installed under the grain surface, and the grain surface can be sealed with a thin film without removing the film during fumigation. It not only saves drugs but also achieves good results.
