How to solve the scaling problem in plate heat exchangers?
Plate heat exchangers are widely used cooling exchange equipment in the vacuum distillation workshop of refineries. The factory incurs significant costs every year due to the fouling of heat exchangers, and when the problem is severe, it can also affect production. Based on the mechanism of fouling layer deposition, fouling can be classified into particulate fouling, crystalline fouling, chemical reaction fouling, corrosion fouling, and biological fouling.
A brief introduction to the application characteristics of fully welded plate heat exchangers
Due to the good welding process used in fully welded plate heat exchangers, there are no non-metallic sealing materials between the heat transfer elements, resulting in high temperature, pressure, and corrosion resistance. The working temperature can reach up to 500 ℃, and the working pressure can reach up to 2.5Mpa, providing a large heat transfer area in a compact space, which enhances the reliability of the heat exchanger.
The structural principle of a plate heat exchanger
The plate heat exchanger is a type of heat exchanger made of thin metal plates pressed into heat exchange plates, which are assembled by stacking. Thin rectangular channels are formed between various plates, allowing for heat exchange through half plates. The four corner holes of the plates and gaskets form the distribution and collection pipes for the fluid, while also separating the hot and cold fluids. The working fluid flows through the narrow and winding channels formed between two plates.
How to improve the efficiency of plate heat exchangers
How to improve the efficiency of plate heat exchangers: The following points explain that to improve the heat transfer coefficient of the heat exchanger, it is necessary to simultaneously increase the surface heat transfer coefficients on both the hot and cold sides of the plates, reduce the thermal resistance of the fouling layer, select plates with high thermal conductivity, and reduce the thickness of the plates to effectively improve the heat transfer coefficient of the heat exchanger.
Reasons for excessive pressure drop in plate heat exchangers
When selecting the area of the plate heat exchanger for the first time, if it is too small and the system piping has not been properly flushed, excessive pressure drop may occur during use.
Tips for Purchasing Food-Grade Plate Heat Exchangers
Heating, sterilization, and cooling are basic production processes in food processing, where food-grade plate heat exchangers are inevitably used. Although they are all food-grade plate heat exchanger manufacturers, the quality of the equipment produced varies significantly. Below are some tips on how to choose a food-grade plate heat exchanger, helping you purchase a higher quality food-grade plate heat exchanger.
