Abstract

The invention relates to monitoring techniques of biogas fermentation process states, in particular to a biogas fermentation process state control system and a biogas fermentation process state control method thereof. Sensors of a detection unit are disposed at corresponding positions in a biogas fermentation tank and used for various state parameters of the biogas fermentation tank; a field failure detection unit judges whether or not the state parameters, such as temperature, pressure and PH value, of the biogas fermentation tank are normal according to detection result of the detection unit, sends out an alarm signal if the state parameters are abnormal for a long time, compares the data to corresponding target values if the state parameters are normal, calculates corresponding corrected values and transmits the corrected values to a heating and insulation unit, a feeding and discharging unit and a stirring unit, thus correcting their running states. The process above is in a continuous cycle, the biogas fermentation process state is monitored and controlled, and fermentation process repeatability and product quality uniformity are improved. The biogas fermentation process state control system and the biogas fermentation process state control method thereof are applicable to monitoring of the biogas fermentation process.

Description

technical field [0001] The invention relates to the monitoring technology of various states in the biogas fermentation process. Background technique [0002] With the progress of society and the improvement of human living standards, the role of fermentation engineering in human life is becoming more and more important. Among them, biogas fermentation engineering is relatively mature in the entire bioengineering. It converts the energy fixed in biomass into Methane gas energy is especially suitable for the treatment of cow manure, sewage, and organic waste. Therefore, biogas fermentation engineering is a technical means that not only has an environmental protection effect, but also can develop biomass energy. Foundation. [0003] The main characteristics of fermentation process production are "finite production" and "no realistic steady state". The fermentation production process is different from the continuous production process. It is an unsteady production operation, t...
