热电偶系统运行翻译-中英对照
一.启动前的检查:
装置启动前应先检查各阀门阀位,螺杆泵及电气控制工况是否符合要求。
二.装置的运行准备,运行和停运:
1.  新装置第一次启动:将螺杆泵进水管转接清水池(水槽及水箱),开启排油阀,排气阀后启动螺杆泵,逐级进液,排气,直至相应筒体满流后关闭相应的排油、排气阀,各级全部满流后继续运行半小时,一般采用循环方式,既运行水也可返回水池(槽或箱)。
2. 一般启动:先将螺杆泵进出水管转接清水池运行半小时,并逐级排气至满流。
3. 装置的运行:处理装置经清水运行半小时,并逐级排气至满流后,将进水管转入废水池进入处理运行,同时根据含油废水的含油浓度确定排油周期,排油只需开启排油阀,并通过排油观察控制开启时间,一般条件下,每班只需开启一次(8小 时一次)。
4. 装置的停运:结束运行前应将螺杆泵进水管转入清水池(槽或箱)运行半小时,然后再停泵,停泵时就关闭所有阀门,保持筒体的满流状态。
第八节  装置运行的注意事项
一.装置应在清水满流的前提下启动,因此启动和停运要清水运行半小时,并在此过程逐级排气。
二.含油废水应经过澄清、隔油设施预处理,泵前应设置机械过滤器。
三.装置运行时应注意废水池液位,以免抽空后磁体空转发热损坏,必要时应设置液位报警信号或液位联动可自控系统。
第九章  化学监督与分析方法
第一节   停炉保护
一.  总则:
锅炉停运腐蚀比运行腐蚀严重得多,所以在锅炉大修,备用时,必须认真做好保护工作,以防腐蚀。
1. 停炉保护方法:
停炉保护方法很多,根据各种不同条件采用不同的方法,常采用的方法有以下四种。
(1)给水压力溢流保护法。
(2)蒸汽压力法。
(3)热炉放水法。
(4)干燥剂或液氨法,联胺法。
a. 给水压力溢流保护法:
炉子停运一天以上至二个月,炉本体内没有工作均可采用此法。当炉子停运降压至0.5—1.0Mpa,开启溢流保护水母管从过热器出口联箱充入除过氧的水至满,从炉子最高点溢流管流出进行保护,溢流水回收到疏水箱。保护期间每班分析一次炉水溶解氧,不合格以换水方式至合格。
b.  蒸汽压力法:
热备用炉和经常开停的炉子采用此法,用压火或经常升火的办法,保持压力0.5Mpa使空气不能进入,保护炉子,并定期分析炉水中氧。
c. 热炉放水
运行炉转入检修,炉子本体没有工作采用此法。具体操作如下:
1、用热电偶监视汽包壁上下温差变化。
2、烧尽煤粉,关主汽门,并汽门,连排门向空排汽门,密闭烟气系统,全开取样门,过热器疏水门,炉子从旁路补给水。
3、降压至5.0Mpa时120—125炉关过热器疏水水门。进行定排,每点一分至半分钟,然后开事故放水降压,并补水保持水位。
4、也可开向空排汽门,炉水放完后,开引风机挡板进行自然通风直至向空排门不冒汽,关闭之。
d. 干燥剂或液氨法、联胺法。
● 对长期停用的锅炉,采用此法。
干燥剂法:用无水氯化钙或经120—140烘的硅胶或生石灰,其用量,前二种0.1—0.2Mpa炉容积,干燥剂放入小盘内或袋中分别放入汽包,各联箱,并记录准确部位,定期检查,失效后定期更换。
● 氨液法:用含氨500mg/L的稀氨溶液充满锅炉。
● 联胺法:用PH≥10,含联胺150—200mg/L的氨—联胺溶液充满锅炉。

II. Regeneration of high speed mixing:
1. Air flushing:
2. Resins separations:
3. Anion resins regeneration:
