Desulfurization equipment is a key facility in industrial production to reduce sulfur dioxide emissions, do a good job of maintenance, can ensure its efficient and stable operation and extend the service life.
Daily inspection is the basis of maintenance.Need to check the operating parameters of the equipment every day, such as pH value, liquid level, flue gas temperature and flow in the absorption tower, etc., to ensure that the indicators are in the normal range; at the same time, observe the appearance of the equipment, check whether there is leakage of pipelines and valves, and deal with the problem of dripping in a timely manner, so as to avoid the damage of corrosive media on the equipment.
Regular maintenance to focus on key components.Desulfurization equipment in the spray system, agitator, mist eliminator and other components need to focus on.Spraying system nozzles are prone to clogging or abrasion, should be regularly cleaned, replaced, to ensure that the slurry is evenly sprayed; agitator bearings and seals need to add lubricant in a timely manner, to prevent friction loss leading to equipment failures; demisting the surface of the easy to adhere to the slurry crystals need to be flushed regularly, to avoid clogging to avoid affecting the efficiency of the demisting.
Preventive maintenance is indispensable.According to the operating condition and service life of the equipment, make a reasonable overhaul and mid-repair plan, and replace the parts with serious wear and tear in advance; regularly carry out anticorrosion treatment on the equipment to prevent the metal parts from being corroded by the desulfurization agent; at the same time, do a good job in the maintenance of the electrical system, and check whether the lines are connected firmly to prevent the occurrence of short-circuits, leakage and other problems.
In addition, the establishment of perfect equipment maintenance files, detailed records of each maintenance time, content and problems, for subsequent maintenance to provide reference basis .
