The importance of plate heat exchangers in the chemical industry
In the early days, plate heat exchangers were mostly used in milk sterilization or beer processing. It has been widely used in the industry as a compact heat exchange device. Through application practice, people gradually have a deeper understanding of its superiority. With the expansion of application fields and the advancement of weaving technology, plate heat exchangers have become an important heat exchange device. Heat exchangers for heating in daily life, condensers on steam turbines, and oil coolers on space rockets all have heat exchangers. It is also widely used in chemical, chemical, and nuclear industries.

Plate heat exchanger scale formation and measures
Since the refrigerant fluid (refrigerated water) receives the heat of the mission fluid (cooling water), the cooling water of the plate heat exchanger is in the process of heat exchange. The temperature rises. At this time, the CaHCO32 and MgHCO32, which are dissolved in water, precipitate CO2 to form CaCO3 and MgCO3 which are slightly soluble in water. Since the degree of melting of CaCO3 and MgCO3 decreases with temperature, it crystallizes from water. The crystals are continuously deposited on the surface of the heat exchanger, forming a very hard scale.

Judge the cause and solution of leakage of plate heat exchanger
The plate heat exchanger is prone to leakage during operation, and there are many reasons for the leakage. According to different reasons, the method of treating the leakage of the plate heat exchanger is also different. Below we will leak the plate heat exchanger. The reasons are briefly analyzed and summarized, and the corresponding solutions are proposed.

HVAC system operation common faults and treatment methods
Plate heat exchanger has the characteristics of high heat transfer coefficient, small pressure drop.compact structure, light weight, small occupied space, convenient area and process combination.strong versatility of parts, wide selection of materials and easy realization of large-scale production.It has been widely used in the fields of food, machinery, metallurgy, petrochemical industry andships, and has become the leading heat exchange equipment in urban central heating engineering.Inorder to ensure the normal operation of the plate heat exchanger and prolong the service life of keycomponents (such as plates and rubber pads), it is particularly important to know the faults of theplate heat exchanger, their causes and treatment methods.
