What happens if the plate heat exchanger is not cleaned for a long time?


The scale plug for a long time causes the deterioration of the heat exchange conditions . The heat transfer surface of the plate heat exchanger exceeds the rated temperature or local overheating, which may cause the heat exchanger to crack and burst, causing an accident. The energy consumption used increases, which 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. As a result, the heat exchanger faces equipment shutdown and maintenance. In serious cases, the original heat exchanger must be scrapped and replaced with new equipment.
The plate heat exchanger is in use. Due to improper operation of water treatment equipment. The water quality control is not up to standard, and the unqualified demineralized 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 precipitates when they are heated and stick to the heating surface of the heat exchanger. Hard scales formed. Due to the poor thermal conductivity of scale, the heat exchange efficiency of the heat exchanger is reduced and the thermal energy is seriously wasted. As a result, the heating effect is affected, and the heating unit has a serious negative impact.
The plate heat exchanger was not cleaned in time, and the scale in the water was not completely filtered, which resulted in the water from the water outlet not being completely filtered and directly supplied to the user. Generally, the domestic hot water unit is basically used for bathing. The long-term contact of the unfiltered water with the skin will have bad results on the human body and affect people's health.
Measures to prevent scaling of plate heat exchangers are to strictly control the water quality during operation. Strict water quality tests must be performed on the water in the system and the softened water in the softened tank, and they can be injected into the pipe network only after passing the test. When the new system is put into operation, the heat exchanger should be separated from the heating system, and after a period of circulation, the heat exchanger should be integrated into the system of the Shandong plate heat exchange unit manufacturer. To avoid impurities in the pipe network from entering the heat exchanger. In the heating system, the dirt collector and filter should be cleaned irregularly, and the pipe network should be kept clean to prevent the heat exchanger from being blocked.
