沼氣發(fā)電是一種較好的糞污沼氣處理方法，它可以將糞污轉化為新型能源并減少對環(huán)境的污染。但是對沼氣發(fā)電機組尾氣排放也需要達標處理。針對該糞肥沼氣發(fā)電機組實際工況和特點，中拓結合多年內燃機尾氣治理的經驗，并從投資成本、運行安全性等方面考慮，采用一臺機組對應一臺脫硝設備的設計方案。包括主體脫硝設備及其輔助裝置生產、工廠檢驗、包裝、運輸、調試、培訓和售后服務等一系列內容。最終糞肥沼氣發(fā)電機組尾氣凈化脫硝項目交付使用并達標運行，在機組滿足NOx原始排放值≤500mg/Nm’(5%02)，溫度范圍在484°-512°的排放條件下，實現(xiàn)NOx≤50mg/Nm3(5%含氧量）的目標排放要求。

　　Biogas power generation is a preferred method for treating fecal biogas, as it converts feces into a new form of energy while reducing environmental pollution. However, the exhaust emissions from biogas generator sets also need to meet emission standards. Based on the actual operating conditions and characteristics of this manure biogas generator set, Zhongtuo, leveraging its years of experience in internal combustion engine exhaust gas treatment, and considering investment costs and operational safety, has adopted a design scheme where one denitration device is paired with one generator set. This includes a series of processes such as the production, factory inspection, packaging, transportation, commissioning, training, and after-sales service of the main denitration equipment and its auxiliary devices. Ultimately, the manure biogas generator set exhaust gas purification and denitration project was successfully commissioned and operated in compliance with standards. Under emission conditions where the original NOx emission value of the generator set is ≤500mg/Nm? (5% O2) and the temperature range is between 484°C and 512°C, the target emission requirement of NOx≤50mg/Nm? (5% oxygen content) was achieved.

　　中拓的萬純SCR脫硝系統(tǒng)可滿足不同溫度使用環(huán)境，選用燃氣機組專用脫硝催化劑以滿足發(fā)電機各種工況使用要求；煙氣混合系統(tǒng)配合精密的尿素量計算控制系統(tǒng)，使整套脫硝系統(tǒng)達到有效的尿素溶液噴射狀態(tài)，可以更好地與尾氣充分混合，大幅度提高反應效率。整套脫硝系統(tǒng)具有安全可靠、背壓小，非常大限度地減少了脫硝設備對內燃發(fā)電機組的影響；同時安裝位置合理，占地面積小，且保養(yǎng)、維修方便。

　　Zhongtuo's Wanchun SCR denitration system can meet different temperature operating environments. It utilizes denitration catalysts specifically designed for gas turbine units to meet the various operating requirements of generators. The flue gas mixing system, coupled with a precise urea quantity calculation and control system, enables the entire denitration system to achieve effective urea solution injection, allowing for better mixing with the exhaust gas and significantly improving reaction efficiency. The entire denitration system is safe and reliable, with low back pressure, greatly reducing the impact of denitration equipment on internal combustion engine generator sets. Additionally, the installation location is reasonable, the footprint is small, and maintenance and repair are convenient.

　　此外，沼氣發(fā)電機組尾氣凈化系統(tǒng)選取可編程控制器PLC作為脫硝系統(tǒng)的自動控制裝置并將各種輔助控制集成編譯，具有體積小、組裝維護方便、可靠性高和抗干擾能力強等特點，使運行維護人員數(shù)量大幅減少；控制系統(tǒng)還可與上位機通訊，便于遠程集中監(jiān)測污染物排放數(shù)據(jù)；其中的人機界面系統(tǒng)，可實時顯示脫硝狀態(tài)數(shù)據(jù)，煙溫狀態(tài)，尿素用量等情況，還可對脫硝系統(tǒng)進行遠程控制并對之前的數(shù)據(jù)進行統(tǒng)計記錄，且控制柜配有觸摸屏，便于運行人員平視操作，進行觀察和監(jiān)視，維護便捷簡單，同時支持遠程通信和集成管理。

　　In addition, the biogas generator set exhaust gas purification system selects a Programmable Logic Controller (PLC) as the automatic control device for the denitration system and integrates various auxiliary controls, featuring small size, convenient assembly and maintenance, high reliability, and strong anti-interference capability, significantly reducing the number of operation and maintenance personnel. The control system can also communicate with the host computer, facilitating remote centralized monitoring of pollutant emission data. The human-machine interface system can display denitration status data, flue gas temperature status, urea consumption, etc. in real time, and can remotely control the denitration system and statistically record previous data. The control cabinet is equipped with a touch screen, facilitating eye-level operation for operators, observation, and monitoring, making maintenance convenient and simple. It also supports remote communication and integrated management.
