Food-grade plate heat exchanger_ In industrial systems, fluids containing particles and fibers enter the fully welded plate heat exchanger. When the flow rate design of the fully welded plate heat exchanger is unreasonable or the channel width is less than the allowable width, particles and fibers will gradually settle at the bottom of the heat exchanger channels, causing increased resistance and poor circulation in the fully welded plate heat exchanger. In severe cases, the heat exchanger will no longer transfer heat, seriously affecting the operation of the system process.
Fully welded plate heat exchangerIt is a common equipment in many industrial sectors such as chemical, petroleum, power, food, and others, playing an important role in production. However, in the heating field, due to improper operation of water treatment equipment, softened water that does not meet the softening requirements is directly fed into the system, causing soluble calcium and magnesium salts in the water to decompose into calcium carbonate and magnesium hydroxide precipitates upon heating, which adhere toFully welded plate heat exchangerthe heated surface, forming hard scale. Due to the poor thermal conductivity of the scale, it results inFully welded plate heat exchangera decrease in heat exchange efficiency and an increase in system resistance, thereby affecting the heating effect and causing serious energy waste for the heating units.
In industrial systems, fluids containing particles and fibers EnterFully welded plate heat exchanger, whenFully welded plate heat exchangerthe flow rate is designed unreasonably or the channel width is less than the allowable width, particles and fibers will slowly deposit at the bottom of the heat exchanger channel, causingFully welded plate heat exchangerincreased resistance to flow, and in severe cases, the heat exchanger will no longer exchange heat, seriously affecting the operation of the system process.
PreventingFully welded plate heat exchangerscaling measures:
1)Fully welded plate heat exchangerDuring operation, strict control of water quality is essential. The water in the system and the softened water in the softening tank must undergo strict quality testing, and only after passing can it be injected into the pipeline.
2) In the heating system, in addition to periodic cleaning of the decontaminator and filter, the cleanliness of the pipeline should also be maintained to preventFully welded plate heat exchangerblockage.
3) Use reasonable filtering devices to ensure that the particle content of the water entering the heat exchanger is belowFully welded plate heat exchangerthe requirements for particle diameter.
In summary, choosing a reasonable method to preventFully welded plate heat exchangerblockage isFully welded plate heat exchangeran important guarantee for the normal operation of production.
