What factors affect the scaling of stainless steel plate heat exchanger equipment?

Stainless steel plate heat exchanger in use, dirt deposits will inevitably appear in the heat transfer surface, the phenomenon of scaling, dirt deposits high thermal resistance, greatly reducing the rate of heat transfer; at the same time due to scaling reduces the flow area, media flow resistance increases, energy consumption increases. Stainless steel plate heat exchanger running quality and the length of time, and daily maintenance, cleaning and maintenance is timely, suitable for a very close relationship. For easy to scale the fluid, can be in the specified time using the appropriate way to descale. Qingdao Ruiputeplate heat exchanger manufacturer for everyone to introduce stainless steel plate heat exchanger equipment scaling by what factors?

Influence of plate heat exchanger scaling factors are many, such as fluid velocity, fluid flow state, composition and content of the fluid components and the structure of the heat exchanger have a certain impact on the formation of fouling, we only find out the main factors in order to make the scaling problem can be effectively solved.

1.Hot surface material and surface quality: for the commonly used carbon steel, stainless steel, corrosion products deposition will affect the fouling, and if the use of corrosion resistance of good graphite or ceramic and other non-metallic materials, it is not easy to occur fouling. The surface quality of the heat transfer surface material will affect the formation and deposition of fouling, the greater the surface roughness, the more conducive to the formation and deposition of fouling.

2.Heat transfer wall temperature: temperature for chemical reaction scale and salt crystallization scale has an important role, the increase in fluid temperature will generally lead to an increase in the rate of chemical reaction and crystallization rate, which has an impact on the amount of dirt deposition, resulting in increased dirt growth rate.

3.Fluid flow rate: in the heat exchanger, the impact of the flow rate of dirt should be considered at the same time its impact on dirt deposition and dirt corrosion, for all kinds of dirt, due to the increase in flow rate caused by the increase in the rate of corrosion than the rate of dirt deposition is more significant, so the rate of growth of dirt as the flow rate increases and decreases. But in the actual operation of the heat exchanger, the increase in the flow rate will increase energy consumption, so the flow rate is not as high as possible, should be from the energy consumption and fouling two aspects to consider.
