1, strictly control the effect of the separator liquid level, in the process requirements of the appropriate position.
2, easy in evaporation crystallization precipitation material, easy to have the pipe, plate evaporator, valves and other fouling blocking phenomenon.
Therefore need to rinse regularly unblocked, or use the measures such as vacuum pumping a remedy.
3, often calibration instrument, sensitive and reliable.
If it is found that instrument malfunction, to timely find the reasons and processing.
4, often to strict inspection, the inspection of equipment, piping, especially mirror glass to regularly check, timely replacement, in case of accidents caused by corrosion.
Before 5, maintenance equipment, pressure release blowdown, and rinse with water cooling, remove residual corrosive liquid equipment.
6, operating and maintenance personnel should wear protective clothing, avoid personal injury hydrothermal, hot steam.
7, remove flange screws should be diagonal remove or tighten, and according to the steps, especially when disassembling, confirmed no liquid to unload, lest the liquid jet, and pay attention to the nozzle can't someone below.
8, overhaul evaporator to material emission clean, with hot water cleaning processing, reoccupy cold water on roof caving to wash out.
Valve at the same time to check on whether it can shut up, or blind, in case the material through the hurt in the process of inspection.
After 9, evaporator water, open manhole let air exchange and cooling below 36 ℃, the maintenance staff to wear good clothes into the overhaul, the outside need someone care, facilitate the accident timely rescue.
