在工业生产中，大量尾气余压往往被白白浪费，成为能源利用的“隐形缺口”。中拓针对山东某生物发酵企业发酵罐尾气处理需求，量身打造余压发电解决方案，将余压转化为稳定绿电，既实现能源回收，又降低生产成本，成为生物发酵行业节能改造的标杆案例。

　　In industrial production, a large amount of exhaust pressure is often wasted, becoming a "hidden gap" in energy utilization. Zhongtuo has tailored a residual pressure power generation solution to meet the tail gas treatment needs of a biological fermentation enterprise in Shandong. The solution converts residual pressure into stable green electricity, achieving energy recovery and reducing production costs. It has become a benchmark case for energy-saving transformation in the biological fermentation industry.

　　01项目背景：尾气余压的“能源潜力”待释放

　　01 Project Background: The "energy potential" of exhaust residual pressure to be released

　　山东某生物发酵企业的发酵罐尾气中，蕴含着未被充分利用的压力能与热能。传统处理模式下，这些能源未经过回收便直接排放，不仅造成能源浪费，还增加了企业环保与能耗成本压力。

　　The exhaust gas from the fermentation tank of a biological fermentation enterprise in Shandong contains underutilized pressure energy and heat energy. Under the traditional processing mode, these energy sources are directly discharged without being recovered, which not only causes energy waste but also increases the pressure on environmental protection and energy consumption costs for enterprises.

　　为破解这一痛点，中拓提供“涡轮机组+永磁直驱发电机+驱控一体电机+直流微网”一体化解决方案，在保障原有生产工艺稳定的前提下，实现尾气余压的高效回收与发电，让“闲置能源”成为企业降本增效的新助力。

　　To solve this pain point, Zhongtuo provides an integrated solution of "turbine unit+permanent magnet direct drive generator+integrated drive control motor+DC microgrid", which achieves efficient recovery and power generation of exhaust gas residual pressure while ensuring the stability of the original production process, making "idle energy" a new help for enterprises to reduce costs and increase efficiency.
