With the development of society and the acceleration of urbanization, the central heating system is becoming more and more mature.

As an efficient heat exchange equipment, plate heat exchangers are widely used in heating systems due to their high heat exchange efficiency, small footprint, light weight, easy disassembly and assembly, and low fouling coefficient.

At present, the plate heat exchanger has become the core component of the central heating indirect heat exchange unit.

However, in practical applications, chlorine corrosion can easily lead to fouling, blockage, corrosion or perforation of the heat exchanger plate, which in turn affects the normal operation of the heat exchanger and brings huge cost pressure or economic losses.

Therefore, it is necessary to do a good job in the selection of heat exchanger plates, scale inhibition, corrosion protection, and safe cleaning to ensure normal production.

In a central heating system, water is mainly composed of tap water and deep well water, which has high hardness.

Due to the small flow interface of the plate heat exchanger, the flow velocity between the plates is relatively low, which deposits on the surface of the heat exchanger, forming secondary fouling, affecting water quality and causing fouling and clogging of the heat exchanger.

Since the thermal conductivity of the dirt layer is very low, the heat transfer resistance is greatly increased, and the heat transfer efficiency of the heat exchanger is reduced to a certain extent.

When a fouling layer is formed on the surface of the plate heat exchanger, the flow area of the equipment will be reduced, the resistance of the fluid flowing through the equipment will increase, and unnecessary cost waste will be caused.

Although the plates of the plate heat exchanger are made of stainless steel and have strong corrosion resistance, they will be corroded if the chloride ion content in the water is high.

If the corrosion is uniformly carried out on the entire metal surface, the corrosion rate will not increase, and the harm caused by corrosion will not be too great.

If the corrosion is concentrated on a certain part of the metal surface, the corrosion rate will increase, and the phenomenon of rust penetration will be easy to occur, which is very harmful. It will not only reduce the working efficiency of the equipment, but also greatly shorten the service life of the equipment and increase the maintenance cost.

Large, will not only reduce the efficiency of the equipment, but also greatly shorten the service life of the equipment and increase maintenance costs.
