Marine heat exchangers have been under long-term heat exchange conditions and are very prone to fouling. At this time, it is easy to cause blockage of the heat exchanger, and there is no way to achieve the original heat exchange effect when the heat exchange efficiency is low. Long-term scale plugging causes deterioration of heat exchange conditions. The heat transfer surface of the heat exchanger exceeds the rated temperature or partially overheats, which may cause the heat exchanger to crack and burst and cause an accident. The increased energy consumption cannot achieve the effect of energy saving. The accumulation of dirt threatens the safe operation of the heat exchanger and shortens the service life of the heat exchanger.
The water treatment equipment does not operate properly during the use of the marine heat exchanger. The water quality control is not up to standard, and unqualified softened water is injected into the heating system, so that the calcium, magnesium, and carbonate in the water will be decomposed into calcium carbonate and magnesium hydroxide after being heated, and the precipitates will adhere to the heating surface of the heat exchanger. Due to the poor thermal conductivity of scale, the heat exchange efficiency of the heat exchanger is reduced and the heat energy is wasted seriously. As a result, the heating effect is affected and the heating unit has a serious negative impact.The marine heat exchanger was not cleaned in time, and the dirt in the water was not completely filtered. As a result, the water from the water outlet is not completely filtered and is directly supplied to the user. Generally, domestic hot water units are basically used for bathing. Long-term contact of unfiltered water with the skin will produce bad results for the human body and affect human health.
