运行前的检验是非常重要的工作,否则投产后再发现上述先天性缺陷,补救维修工作难以进行。沼气工程建设除工艺设计和结构设计科学合理外,还应当检查施工、安装质量,确保发酵装置不漏水、不漏气,一切附属设备完好。新建的沼气发酵装置(消化器或反应器)在投料前向装置内注满清水,并增压至4.9~9.8千帕,经24小时观察压力下降小于3%,即可认为池体密封符合要求。否则应立即采取补救措施,再
Pre-operation inspection is a very important task, or put into operation and then found the above congenital defects remedial maintenance work difficult. In addition to process design and structural design of biogas project construction is scientific and reasonable, but also check the construction, installation quality, to ensure that the fermentation unit is not water leakage, airtight, all ancillary equipment intact. The newly constructed biogas fermentation unit (digester or reactor) is filled with clean water before charging and pressurized to 4.9-9.8 kPa, and the pressure drop of less than 3% after 24 hours of observation can be considered that the seal of the cell body meets the requirements . Otherwise, remedial measures should be taken immediately
