激光氧分析儀:解決危廢破碎工藝安全與效率難題

危廢破碎工藝的特點與氧氣監(jiān)測需求

危險廢物(危廢)破碎工藝是危廢處理的前端關鍵環(huán)節(jié),其核心目標是將大塊危廢物料破碎成適宜后續(xù)處理的粒度。然而,危廢成分復雜,可能包含易燃易爆物質(如有機溶劑、金屬粉末等),且在破碎過程中易產(chǎn)生粉塵、揮發(fā)性氣體及高溫環(huán)境。這些特性使得工藝環(huán)境存在以下風險:

爆炸風險:破碎過程中產(chǎn)生的可燃粉塵與氧氣混合可能達到爆炸Ji限,尤其在密閉管道或設備中,氧氣濃度過高會顯著增加燃爆風險。

工藝效率低下:若氧氣含量失控,可能導致物料氧化反應加劇,影響后續(xù)焚燒或化學處理的穩(wěn)定性。

設備腐蝕與堵塞:部分危廢在富氧環(huán)境下會加速腐蝕設備,或形成焦油、顆粒物沉積,降低設備壽命。

因此,實時、準確監(jiān)測工藝管道中的氧氣含量,是保障危廢破碎工藝安全、高效運行的關鍵。

激光氧分析儀

激光氧分析儀的技術優(yōu)勢

激光氧分析儀基于可調諧半導體激光吸收光譜技術(TDLAS),通過檢測激光穿過氣體時的吸收光譜來量化氧氣濃度,其核心優(yōu)勢包括:非接觸式測量、抗干擾能力強、響應速度快與高穩(wěn)定性、適應惡劣環(huán)境、使用壽命長。

激光氧分析儀在危廢破碎工藝中的具體應用

在危廢破碎工藝中,激光氧分析儀主要應用于以下場景:

惰化保護系統(tǒng),危廢破碎設備(如破碎機、輸送管道)需通過充氮維持惰性環(huán)境。激光氧分析儀實時監(jiān)測氧氣濃度,當檢測值超過安全閾值時,觸發(fā)氮氣注入系統(tǒng),迅速降低氧含量,防止燃爆風險。

案例:某危廢處理廠在破碎機出口管道安裝激光氧分析儀,結合自動充氮裝置,成功將氧含量控制在6%以下,避免粉塵爆炸事故。

工藝參數(shù)優(yōu)化,通過監(jiān)測不同工藝段的氧氣分布(如破碎區(qū)、輸送區(qū)),可動態(tài)調整通風量或破碎速度,減少物料氧化反應,提升后續(xù)焚燒效率。例如,在高溫破碎工藝中,實時氧含量數(shù)據(jù)可用于平衡熱解與氧化反應,降低殘渣含碳量。

設備保護與維護,高粉塵環(huán)境下,傳統(tǒng)傳感器需頻繁清理或更換,而激光氧分析儀的光學視窗通過吹掃單元(含過濾、穩(wěn)流裝置)保持清潔,無需停機維護,顯著降低運維成本。

激光氧分析儀憑借其非接觸、高精度、強抗干擾的特性,已成為危廢破碎工藝中不可或缺的安全保障工具。通過實時監(jiān)測與智能調控,它不僅顯著降低了燃爆風險,還提升了工藝效率,為危廢處理行業(yè)的可持續(xù)發(fā)展提供了技術支撐。
