熱電偶系統運行翻譯-中英對照
一.啟動前的檢查:
裝置啟動前應先檢查各閥門閥位,螺桿泵及電氣控制工況是否符合要求。
二.裝置的運行準備,運行和停運:
1. 新裝置第一次啟動:將螺桿泵進水管轉接清水池(水槽及水箱),開啟排油閥,排氣閥后啟動螺桿泵,逐級進液,排氣,直至相應筒體滿流后關閉相應的排油、排氣閥,各級全部滿流后繼續運行半小時,一般采用循環方式,既運行水也可返回水池(槽或箱)。
2. 一般啟動:先將螺桿泵進出水管轉接清水池運行半小時,并逐級排氣至滿流。
3. 裝置的運行:處理裝置經清水運行半小時,并逐級排氣至滿流后,將進水管轉入廢水池進入處理運行,同時根據含油廢水的含油濃度確定排油周期,排油只需開啟排油閥,并通過排油觀察控制開啟時間,一般條件下,每班只需開啟一次(8小 時一次)。
4. 裝置的停運:結束運行前應將螺桿泵進水管轉入清水池(槽或箱)運行半小時,然后再停泵,停泵時就關閉所有閥門,保持筒體的滿流狀態。
第八節 裝置運行的注意事項
一.裝置應在清水滿流的前提下啟動,因此啟動和停運要清水運行半小時,并在此過程逐級排氣。
二.含油廢水應經過澄清、隔油設施預處理,泵前應設置機械過濾器。
三.裝置運行時應注意廢水池液位,以免抽空后磁體空轉發熱損壞,必要時應設置液位報警信號或液位聯動可自控系統。
第九章 化學監督與分析方法
第一節 停爐保護
一. 總則:
鍋爐停運腐蝕比運行腐蝕嚴重得多,所以在鍋爐大修,備用時,必須認真做好保護工作,以防腐蝕。
1. 停爐保護方法:
停爐保護方法很多,根據各種不同條件采用不同的方法,常采用的方法有以下四種。
(1)給水壓力溢流保護法。
(2)蒸汽壓力法。
(3)熱爐放水法。
(4)干燥劑或液氨法,聯胺法。
a. 給水壓力溢流保護法:
爐子停運一天以上至二個月,爐本體內沒有工作均可采用此法。當爐子停運降壓至0.5—1.0Mpa,開啟溢流保護水母管從過熱器出口聯箱充入除過氧的水至滿,從爐子最高點溢流管流出進行保護,溢流水回收到疏水箱。保護期間每班分析一次爐水溶解氧,不合格以換水方式至合格。
b. 蒸汽壓力法:
熱備用爐和經常開停的爐子采用此法,用壓火或經常升火的辦法,保持壓力0.5Mpa使空氣不能進入,保護爐子,并定期分析爐水中氧。
c. 熱爐放水
運行爐轉入檢修,爐子本體沒有工作采用此法。具體操作如下:
1、用熱電偶監視汽包壁上下溫差變化。
2、燒盡煤粉,關主汽門,并汽門,連排門向空排汽門,密閉煙氣系統,全開取樣門,過熱器疏水門,爐子從旁路補給水。
3、降壓至5.0Mpa時120—125爐關過熱器疏水水門。進行定排,每點一分至半分鐘,然后開事故放水降壓,并補水保持水位。
4、也可開向空排汽門,爐水放完后,開引風機擋板進行自然通風直至向空排門不冒汽,關閉之。
d. 干燥劑或液氨法、聯胺法。
● 對長期停用的鍋爐,采用此法。
干燥劑法:用無水氯化鈣或經120—140烘的硅膠或生石灰,其用量,前二種0.1—0.2Mpa爐容積,干燥劑放入小盤內或袋中分別放入汽包,各聯箱,并記錄準確部位,定期檢查,失效后定期更換。
● 氨液法:用含氨500mg/L的稀氨溶液充滿鍋爐。
● 聯胺法:用PH≥10,含聯胺150—200mg/L的氨—聯胺溶液充滿鍋爐。
