Precautions for desulfurization operation after maintenance?
1、嚴格執(zhí)行《脫硫系統(tǒng)操作規(guī)程》。
1. Strictly implement the operation regulations of desulfurization system.
2、加強除霧器沖洗
2. Strengthen the flushing of demister
暫定90分鐘沖洗一次，注意脫硫塔液位，不要溢水，可適當排空。
It is tentatively scheduled to flush once every 90 minutes, pay attention to the liquid level of desulfurization tower, do not overflow, and drain properly.
The pH value is normally controlled between 5.5 and 6.3. Strictly prevent the pH value from exceeding 68. Strictly control the operation when the pH value is lower than 5.5. Manually measure the pH value in each shift and compare the accuracy of pH meter display.
4、加強壓濾
4. Strengthen pressure filtration
每班必須壓濾，壓濾時間不低于15小時或石膏厚度不超過1厘米。
Each shift must be pressure filtration, pressure filtration time is not less than 15 hours or gypsum thickness is not more than 1 cm.
5、控制脫硫塔液位
5. Control the liquid level of desulfurization tower
正常控制在3.5至4.2米，嚴謹?shù)陀?.5米或高于4.3米運行。
The normal control is 3.5 to 4.2 meters, and the operation is strictly lower than 3.5 meters or higher than 4.3 meters.
Keep the liquid level of slurry supply tank, process water tank and flushing water tank between 1.5m and 2.5m, and make up water for flushing water tank in time, so as to ensure the flushing water for mist eliminator;
In case of any abnormal situation, report to the workshop director and environmental protection engineer in time, such as abnormal current change of each pump, flue gas pressure at the inlet of desulfurization tower, water level of each pool, etc; When the following parameters reach the corresponding data values, the desulfurization tower shall be overhauled.
8、加強設備巡檢
8. Strengthen equipment inspection
保證供水壓力，確保設備冷卻水正常；查看運行設備油位是否正常；查看
Ensure water supply pressure and normal cooling water of equipment; Check whether the oil level of running equipment is normal; see
運行設備有無異因等。如有問題及時解決，解決不了及時匯報車間主任及環(huán)保專工；
Whether there are any abnormal reasons for the operation of the equipment. If the problem is solved in time, report to the workshop director and environmental protection engineer in time;
9、加強除灰運行，嚴謹布袋旁路運行。
9. Strengthen the operation of ash removal and strictly control the operation of bag by-pass.
10. Equipment maintenance: standby pumps for mist eliminator flushing water pump, process water pump and sump pump shall be prepared. When the pump fails during operation, it shall be replaced and put into operation within 3 hours. The maintenance workshop shall deal with the equipment defect immediately after receiving the notice of equipment defect.
