The invention discloses a granary compound gas monitoring system. The compound gas monitoring system comprises a gas impurity filter, a flow quantitative control device and a compound gas detector which are sequentially connected through a connection pipe, wherein a negative pressure source is connected with the tail end of the connection pipe and the front end of the connection pipe is arranged in a granary; the flow quantitative control device and the compound gas detector are respectively connected with a control module. The compound gas monitoring system disclosed by the invention utilizes negative pressure to pump gas in the granary and utilizes the compound gas monitoring system to carry out real-time monitoring and analysis on various indexes including gas types, concentrations and the like, so that the quality and the safety of grains stored in the granary can be guaranteed, and technical supports and scientific evidences are provided for scientifically storing the grains.
Description
technical field [0001] The invention relates to a gas monitoring device, in particular to a granary composite gas monitoring system. Background technique [0002] During the storage of grain in the granary, the gas in the granary will have a greater impact on the storage of grain. Therefore, real-time monitoring of multiple indicators such as oxygen, carbon dioxide, and phosphine gas concentrations in the granary is of great significance for ensuring the quality and safety of grain stored in the granary. The existing granary composite gas monitoring system has single function and poor effect, and cannot provide technical support and scientific basis for scientific grain storage. Contents of the invention [0003] The purpose of the present invention is to provide a granary composite gas monitoring system, which can monitor multiple indicators such as the gas type and concentration of the grain stored in the granary in real time, so as to ensure the quality and safety of t...
