Carbon dioxide gas detector in the grain storage project application
This paper introduces the application of automatic monitoring system of CO2 concentration of grain silo in grain storage engineering, with infrared gas analyser to monitor the CO2 concentration of grain silo with high precision and reliable performance, can be long-term continuous online measurement, for the control of CO2 concentration of air-conditioned grain storage provides an effective way. And among them, CO2 automatic monitoring system is a system that adopts advanced detection and self-control technology to realise fully automatic measurement and data processing of CO2 concentration in grain silo.
The system is the key to realise the air-conditioning process and ensure the process concentration, and its main functions are as follows: real-time automatic acquisition, conversion and transmission of CO2 data of grain storage, data display, printing, data management (including data recording, data analysis and processing, alarm prompting, reserved data communication, etc.), and it has the switching function of manual and automatic operation, and it can realise the open-type setup and adjustment of the system parameters, and it is convenient for upgrading, updating and optimizing the settings. It can realise open setting and adjustment of system parameters, which is convenient for upgrading, updating and optimizing settings.
The system schematic diagram is as follows: Keywords: grain storage, CO2 gas-conditioned grain storage, infrared gas analyser 1. Overview of the grain storage project is a multidisciplinary set of agriculture, biology, construction, environmental protection, chemical engineering, instrumentation, computer technology and other multidisciplinary systematic project, with the rapid development of China's modernisation, the construction of the "green granary" is the current grain storage industry, the construction of the "green granary" is the current grain storage industry. With the rapid development of China's modernisation, the construction of "Green Grain Warehouse" is an important issue in the current grain storage industry. In the process of grain storage, in order to ensure the quality of grain storage, must prevent grain storage pests, mould damage.
For a long time, China usually adopts phosphine, ethylene oxide and other chemicals to fumigate the grain to achieve the purpose of killing pests. Carbon dioxide (CO2) air-conditioned grain storage technology research as early as 1917 on the insecticide test, after 40 years due to the use of cheap insecticides to limit its development, after the insecticide residues, pollution of the environment, the destruction of the ecological environment and pest resistance to increase the problem of increasingly attracted people's attention to the demand for natural and green food, so that CO2 air-conditioned grain storage method has re-caught the attention of people. People's attention, the United States, Japan, Russia, Australia and other economically developed countries have gradually reduced the use of chemicals in grain storage, to the low temperature, air-conditioning, physical and biological integrated prevention and control of ecological grain storage direction, and in the CO2 air-conditioning grain storage technology on a large number of studies and experiments, and the successful application of the establishment of commercial use of norms.
