摘要
Abstract
The industrial-grade supercritical water oxidation system from the perspectives of process scheme and wastewater feed pump were discussed respectively.After comparing the hydrogen peroxide scheme,it was highly likely that the method of producing O2 in the air separation unit would become the main-stream way for the system to obtain oxidants in the future.The overall quality of the organic wastewater was poor.The wastewater feeding process was preliminarily designed based on the idea of pre-neutralization,cold feeding,and ensuring the long-term operation of the feeding pump.A filter was set up to reduce the solid content,and differential pressure transmitter was equipped.Relevant instruments were interlocked to achieve online monitoring and continuous operation of the device.As an important piece of equipment in the entire section,the wastewater feed pump of the BB5 model clearly defined the design points and precautions from aspects such as the pump body structure,material selection,mechanical seal selection,and flushing plan,making contributions to future selection.关键词
