Abstract

The invention discloses a methane fermentation intelligent management system, belonging to a methane generating automation device and aiming at providing the system which can automatically manage intensification large-scale methane generation. The system comprises a computer, a field data acquisition device and a sensor; a sensor (3) arranged on all major devices of a fermentation system is connected with the field data acquisition device (2) by a communication cable; the field data acquisition device is connected with the computer (1) by the communication cable. The system not only realizes the conversion of the methane fermentation from the miniaturization production mode to the large-scale concentration efficient mode, but also intuitively displays all major processing equipment and all technological parameters by a configuration device through the sensor in a pattern or digital mode, conveniently realizes the monitoring of the whole production system, increases the working efficiency, has the advantages of low cost, high waste water processing efficiency, high gas generation rate and the like, and is the ideal management system matched with large-scale poultry and livestock farms.

Description

Technical field: [0001] The invention relates to an intelligent management system, in particular to an intelligent management system for large-scale biogas production. Background technique: [0002] As we all know, most of the traditional biogas production equipment are household biogas digesters, which have the disadvantages of wide distribution, small scale, and low gas production rate, which cannot meet the requirements of intensive large-scale production. With the rapid development of animal husbandry, the scale of livestock and poultry breeding continues to expand, and the daily excrement and other wastes discharged by livestock and poultry farms are increasing, which will not only cause serious environmental pollution, but also easily cause diseases of livestock and poultry, which restricts the livestock and poultry farm itself. If a large-scale biogas project can be built near the farm, it can not only effectively solve the problems of fuel and fertilizer, but also pr...
