Safe use and maintenance measures of Industrial Boiler Steam Boiler in Chemical Plant
How to prevent the corrosion of industrial boiler steam boiler in chemical plant: it is necessary to analyze the root of the problem from the root of the problem, so the corrosion of steam boiler should be solved from the elements that lead to corrosion. In principle, the corrosion of steam boiler is a kind of electrochemical corrosion. A layer of electrolyte solution film formed by absorbing water from air and CO2 on the surface of boiler, or forming many, many small primary batteries on the surface of metal in weak acid and neutral dissolution. Iron is used as negative electrode, and the lost electrons are oxidized to Fe2. On the positive pole, the oxygen in the dissolved water is recovered to obtain electrons. The structure of corrosive hair organisms is relatively loose. In 2005, the diffusion of metal ions can not be prevented, and the corrosion process will be carried out one after another.
Second, how to deal with the sewage of industrial boiler steam boiler in chemical plant: the sewage discharge of boiler is also an index to consider steam boiler. Now it is said that environmental protection should be carried out, and sewage discharge should be called environmental protection within a certain range. The sewage discharge of steam boiler should be discharged frequently and less, that is to say, the frequency of discharge should be more, but the amount of each drainage should be controlled within a small range, which can not only ensure that the supply of steam will not be affected, but also keep the quality of pot water within the scope of the specification all the time. There will be no big wavering, which is very beneficial to boiler maintenance.
3. Protection and maintenance of industrial boilers and steam boilers in chemical plants:
1. Burners should be removed from boiler body every two months and foreign bodies such as carbon accumulation and dust should be carefully removed. The photoelectric tube is scrubbed once a month on the smooth surface, the fuel filter should always keep clean and filtering function; carefully clean the filter net in the oil pump, do not damage the gasket. The burners shall not be idled without oil to avoid damage to the oil pump.
2. When the boiler is protected and maintained, it is necessary to block the power supply and relieve the pressure.
3. The safety valve is pulled once a day to prevent rust failure.
4, the water level meter should be kept clean at all times, open the cleaning valve once a day to ensure that the water level is clear.
5. When the boiler stops running for a long time, the power supply should be blocked and the maintenance operation should be done well: (1) dry maintenance, release furnace water after shutdown, scour the dirt in the furnace, dry the pot with burners and dry the pot for too long. Avoid damage to the boiler), then drain all the boiler gas and close all the pipe valves and check them every three months. (2) Wet maintenance is suitable for boilers whose shutdown period is not more than one month. After shutdown, the furnace water is released, the discharge is clean and filled with clean water, the power supply is blocked and the valve is closed.
