A detection system for the total solid content of the fermented liquid during the continuous anaerobic fermentation of water hyacinth and rice straw

Abstract

The invention discloses a detection system for the total solid content of the fermented liquid in the continuous anaerobic fermentation process of mixing water hyacinth and rice straw, comprising: a sample tank containing the fermented liquid to be tested, a cover fastened on the sample tank, There are 7 windows in the cover body, which are respectively equipped with filters with different transmission wavelengths, a light source located above the sample tank, a detector with adjustable position, which is used to detect the diffuse reflectance at the corresponding position on the cover body, a control unit, It is used to control the position of the detector so that it detects the diffuse reflectance at the 7 windows, and calculates the total solid content in the fermentation broth to be tested according to the diffuse reflectance at the 7 windows. The method of the invention can quickly and effectively realize the rapid, non-destructive, low-cost and environmentally friendly detection of the total solid content in the fermentation broth, and plays a huge role in quickly obtaining information on the components of the fermentation broth and guiding the utilization and processing of the fermentation broth in the later stage.

Description

technical field [0001] The invention relates to the technical field of total solid content detection, in particular to a detection system for the total solid content of fermented liquid in the process of water hyacinth and rice straw mixed continuous anaerobic fermentation. Background technique [0002] The research and development of green renewable energy has become the focus of scientific research work in all countries in the world. Bioenergy will be an important part of future sustainable energy systems. Rice straw and water hyacinth are rich in sources and are one of the first choices as energy raw materials. After a certain amount of mixed silage pretreatment, the two can be used for continuous anaerobic fermentation to produce useful renewable and clean energy methane. In the continuous anaerobic fermentation process, the optimal addition of raw materials, that is, the organic loading rate of the anaerobic fermentation system has always been the focus of researchers ...

AI Technical Summary

Problems solved by technology

[0008] The steps of this method are cumbersome, and repeated weighing and drying are required many times before drying to constant weight, and each stage consumes a lot of time

When heating with a muffle furnace, it is necessary to control multiple temperatures and multiple times in stages, which requires a lot of manpower and time.

Commonly used methods cannot achieve fast and real-time detection, that is, they cannot quickly obtain useful information and accurately and quickly guide the feeding situation
