從數據到價值:煙氣監測賦能玻璃生產

《中共中央國務院關于深入打好污染防治攻堅戰的意見》中明確指出,“十四五”期間,要大力加強細顆粒物(PM2.5)和臭氧污染協同控制,推進氮氧化物(NOx)和揮發性有機物(VOCs)協同減排。玻璃工業是NOx、顆粒物等污染物重要排放行業。2023年1月實施的《玻璃工業大氣污染物排放標準》(GB 26453—2022)大幅提升環保要求:新增 N?O、CH?等溫室氣體控制指標,將 SO?排放限值收緊至 30mg/m³ 以下,NO?限值降至 100mg/m³(特殊地區執行 50mg/m³),顆粒物排放需≤10mg/m³。從根本上引導玻璃行業采用無毒無害原輔材料,推進實施燃料結構、燃燒技術以及窯爐結構優化,降低能源消耗,推動玻璃工業綠色化、低碳化發展。

在 “雙碳” 目標驅動下,玻璃行業被納入高耗能行業節能降碳改造清單,要求 2025 年前單位產品能耗較 2020 年下降 13.5%。地方政策進一步加碼,如長三角、珠三角地區對光伏玻璃、浮法玻璃企業實施差異化減排要求,未達標的企業面臨限產、停產風險。

 

煙氣分析是玻璃熔窯管理的“眼睛” ,實時洞察窯爐氣氛和脫硫脫硝工藝狀況,為實現精準調控、降本增效和節能減排提供不可或缺的數據依據

應用點:

1.窯內狀況分析

2.凈化裝置狀況分析

3.排放監測

影響窯內狀況分析

  • 基于檢測窯況氣氛,調整工況,在保證生產正常運行的前提下節省燃料,間接減少碳排放。

  • 基于監測 O?、CO 數據調整工況,從根本上避免碳粉與 O? 過度反應,防止低溫分解的硫酸鹽減少、高溫澄清分解的硫酸鹽增多而導致的因大量澄清氣體(O?和 SO?)在過程中排出不徹底而產生氣泡的問題。
