Small Energy Bio-gas Ferment Design Manufacture And Analysis

The aim of this paper is to resolve the problems of North biogas project, according to the geographical conditions of North, especially Hohhot and Baotou vicinity. This thesis deals with the design, simulation analysis and manufacture of small-scale energy biogas fermenter. To promote the study of methane fermentation in this region, experimental equipment were designed. This study includes the following Contents:1、Extensive researchs were conducted and a large of biogas projects and biogas fermentation equipment information were collected. The factors of methane fermentation efficiency, such as temperature, ingredients C/N ratio and stir, were comprehensiveiy compared and Analysed.2、The overall scheme of small-scale energy biogas fermenter wre established and the·principle structure,stiffness structure, precision structure and control structure of biogas fermenter were designed.3、For the main force parts of gas tank, we analysed the stress and strain.4、The overall performance biogas fermentor combined with biogas and solar fermenter were manufactured.Useing computer-aided software (Solidworks and Autocad), we established the overall modeling of small-scale energy biogas fermenter and designed the small-scale energy biogas fermenter. We utilize AN SYS Workbench to analyse stress and strain of the main force parts of gas tank.The main innovation points of this study:(1)This design has completed the biogas and the solar energy that are the kinds of c lean energy supplement each other.(2)This Design changes the biogas pool or fixed type methane tank that can not mo ve and solves the difficult problem of cleaning and loading in the clean-up of biogas wast e.The biogas fermentation tank of small energy that was designed and produced provi des the debugging experiment equipment for in-depth study of Biogas Engineering.The cl ean and renewable energy that is produced the equipment is able to solve the demand of e gas and anaerobic fermentation.
