Biological drying process digital monitoring system for reactor

Abstract

The invention relates to a biological drying process digital monitoring system for a reactor. A data collection module is installed at the top of the reactor, is connected with various sensors, and is used for sorting and packaging environment and material text data sensed by the sensors and material spectral information collected by a hyperspectral camera, and transmitting the environment and material text data and the material spectral information to a cloud platform; the hyperspectral camera and a dome light source are mounted on the data collection module, the hyperspectral camera is used for shooting spectral information of materials in the reactor, and the dome light source is used for providing a stable and uniform light source for the hyperspectral camera; the cloud platform receives the data of the data collection module and processes the text data to obtain environmental parameters in the reactor; the cloud platform further comprises a neural network model for judging the decomposition degree of the materials according to the spectral information of the materials, and whether the materials are decomposed or not is predicted through the neural network model by receiving the spectral information. The system can continuously, dynamically and accurately monitor the internal environment and material parameters of the reactor in an unattended manner.

Description

technical field [0001] The invention relates to the field of biological drying, in particular to a digital monitoring system for a biological drying process of a reactor. Background technique [0002] Biological drying treatment is an important means of dealing with urban organic waste, also known as biological drying and biological stabilization. Traditional biological drying was first proposed by Jewell et al. of Cornell University in the United States in 1984 when they studied the operating parameters of cow dung biological drying, and defined it as the use of biothermal energy generated by the degradation of organic matter during microbial high-temperature aerobic fermentation. A drying treatment process that promotes water evaporation through process control means to achieve rapid water removal. Its main purpose is to reduce the moisture content, preserve the organic matter of the material while drying, instead of degrading the organic matter; in the shortest possible ...

AI Technical Summary

Problems solved by technology

[0003] The current monitoring devices and methods for the biological drying process are relatively traditional, and cannot continuously and dynamically obtain the change values ​​of the internal environment of the reactor and the parameters of the material itself during the biological drying process. If you want to measure the value of any position inside the stack, you need to change the physical structure design of the equipment, which causes inconvenience in the use of the equipment

At the same time, the existing technology cannot form the temperature, water content, electrical conductivity and other data on the three-dimensional structure of the pile, and it is difficult to study the change law of the entire pile environment

Secondly, for the problem of inaccurate measurement of material moisture changes

Moisture content is the most important indicator of the biological drying process. However, most of the sensors used in this field are soil sensors. The data are inaccurate, unstable, and unscientific, because the research and development of soil sensors are calibrated through a large number of different types of soils. However, it is very unscientific to directly measure the moisture content of organic waste

Finally, the measurement range is incomplete

At present, most of the existing technologies monitor indicators such as temperature, water content, oxygen concentration, and ammonia concentration, but some important indicators cannot be monitored in real time, such as degree of decay, heavy metal content, hydrogen sulfide concentration, etc. Inconvenience caused during production
